Los Angeles City was the first large settlement due to its location, natural harbor, and water availability. Expansion followed land availability and demand for affordable housing.

Los Angeles City was the principal huge settlement nearby because of a few elements, including its area close to the coast, its regular harbor, and the accessibility of water from the Los Angeles Stream. These variables made the region appealing for settlement and worked with the development of exchange and business. As the city developed, so did the encompassing regions, prompting the arrangement of Los Angeles Area.

The development of Los Angeles and its encompassing regions can be credited to a few elements, including the accessibility of land, the development of the transportation organization, and the rising interest for reasonable lodging. As the populace developed and metropolitan regions turned out to be more packed and costly, individuals started to move endlessly farther to track down more reasonable lodging and bigger parts. This pattern has proceeded right up 'til now, with suburbanization and endless suburbia prompting the development of urban areas and towns past the conventional limits of Los Angeles Province.

Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.

Secretions that are added as food moves through the GI tract assist in digestion and absorption.

The GI tract, which includes organs such as the stomach, small intestine, and large intestine, is responsible for the digestion and absorption of nutrients from the ingested food. Various secretions are released along the GI tract to aid in the digestive process.

These secretions include enzymes, such as amylase, proteases, and lipases, which break down carbohydrates, proteins, and lipids respectively into smaller molecules that can be easily absorbed. Other secretions, such as bile from the liver and pancreatic juices from the pancreas, help in the emulsification and digestion of fats.

In addition to enzymes, the GI tract secretes mucus, which lubricates and protects the lining of the digestive organs. It also releases hormones that regulate digestive processes, such as gastrin, secretin, and cholecystokinin, which help control the secretion of digestive enzymes and the movement of food through the GI tract.

Photosynthesis in chloroplasts involves major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation. It begins with light-dependent reactions in photosystems I and II, followed by electron transport and ATP synthesis.

Step 1: Photosynthesis is a complex process that occurs in the chloroplasts of plants, involving several major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation.

Step 2:Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. It occurs in the chloroplasts, specifically in three main stages: light-dependent reactions, electron transport chain, and the Calvin cycle.

During the light-dependent reactions, light energy is absorbed by chlorophyll molecules in photosystem II (PSII) and photosystem I (PSI). In PSII, water molecules are split, releasing electrons, protons (H+ ions), and oxygen. The electrons move through an electron transport chain, creating a proton gradient across the thylakoid membrane. This gradient is essential for ATP synthesis by ATP synthase, using the energy from the electron flow.

In PSI, electrons are re-energized by absorbing more light energy and are ultimately used to produce NADPH, another energy carrier. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle.

The Calvin cycle, also known as the light-independent reactions or carbon fixation, occurs in the stroma of the chloroplast. It uses ATP, NADPH, and carbon dioxide (CO2) to produce glucose (G3P), which serves as a building block for sugars and other organic compounds. The cycle regenerates the starting molecule, ribulose bisphosphate (RuBP), allowing the process to continue.

Answer:

Protecting an entire ecosystem is preferable over protecting a single species because ecosystems are complex networks of interactions between living and non-living things, where each species plays a vital role in maintaining the balance and function of the ecosystem. A single species alone cannot be viewed in isolation from its environment and the other species that it interacts with.

If one species is lost or endangered, it can have a cascading effect on the rest of the ecosystem. For example, if a predator species disappears, the prey population may explode and cause environmental imbalances. Similarly, human activities such as deforestation and pollution can harm multiple species and alter the ecosystem's dynamics, causing long-term damage.

In contrast, protecting an entire ecosystem ensures the conservation of all its components, preserving the natural balance and the services it provides to humans, such as clean air, water, and soil. It also ensures the long-term survival of all the species within the ecosystem, including those that may not be currently at risk but may become endangered in the future.

Therefore, while conservation efforts can focus on protecting specific threatened species, a more comprehensive approach that protects entire ecosystems is necessary for maintaining healthy and sustainable environments for all species, including humans.

Answer:

Protecting an entire ecosystem is preferable over protecting a single species because ecosystems are interconnected, dynamic, and interdependent systems.

Protecting an entire ecosystem helps to preserve its biodiversity, which is crucial for maintaining ecosystem resilience and adaptability to environmental changes. Biodiversity provides the foundation for ecosystem services such as pollination, nutrient cycling, and climate regulation, which are essential for human well-being. Protecting a single species without considering its role in the broader ecosystem may not address the underlying causes of its decline, and other species within the ecosystem may still be at risk.

Furthermore, ecosystems provide habitat for multiple species, and protecting the entire ecosystem ensures that all species within it are safeguarded. This approach avoids a narrow focus on a single species and considers the broader ecological context. It also helps to prevent unintended consequences, such as overpopulation of one species leading to imbalances in the ecosystem, which can have negative consequences for other species and the ecosystem as a whole.

Lastly, protecting an entire ecosystem promotes a holistic approach to conservation that considers the interconnectedness of all living and non-living components of the ecosystem. It recognizes that ecosystems are dynamic and constantly changing, and that conservation efforts need to be adaptive and comprehensive to effectively address complex ecological issues. By protecting the entire ecosystem, we can better conserve the natural processes, functions, and interactions that sustain all species within it, including humans.

In conclusion, protecting an entire ecosystem is preferable over protecting a single species because it considers the interconnectedness of species, promotes biodiversity conservation, ensures habitat protection for multiple species, and adopts a holistic approach to conservation. By safeguarding the entire ecosystem, we can better preserve the ecological integrity, resilience, and sustainability of natural systems, which are essential for the well-being of all species, including humans.

A. Water flows into cracks in a rock, freezes, and expands, pushing against the crack making it wider.

B. Wind gusts carry large amounts of sand across the landscape creating a sandstorm.

C. Plant roots expand cracks in rocks as the plant grows.

D. Sand particles in the blowing wind may act like sandpaper to rub against the rocks and wear off small particles.

E. Oxygen in the air reacts with iron ore in a rock creating streaks of rust

The correct options in the question above are:

Options A, C, D, and E.

Explanation:

First, Weathering is the actions that lead to the gradual but continuous breakdown of rocks and minerals into soils. There are two main kinds of weathering: mechanical  weathering and chemical weathering.

From the question above, options A, C, and D are all examples of mechanical weathering where rocks are broken down physically into smaller pieces.

Option B would have also been correct but didn't mention that the sandstorm brushed against the rock or collided with it.

While option E is an example of chemical weathering because of the chemical reaction between the oxygen in the air and the iron ore in rock. This results in the breakdown of minerals that are rich in iron forming new compounds creating rust.

Answer:

Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.

Everyday life examples:

(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.

(2) Tubes of bicycles are filled by the pumps that compress the air.

(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.

4) oxygen bottles in medical institutes for helping the patient to breathe.

The genetic code allows each amino acid to be coded for by multiple codons. Thus, option B is correct.

The genetic code is the set of rules that determines how the information contained within DNA or RNA sequences is translated into proteins, specifically into amino acids. Each amino acid is represented by a combination of three nucleotides called a codon. Since there are 4 different nucleotides (adenine, cytosine, guanine, and uracil in RNA; or adenine, cytosine, guanine, and thymine in DNA) and each codon consists of 3 nucleotides, there are 4³ = 64 possible codon combinations.

However, there are only 20 standard amino acids used in protein synthesis. This means that the genetic code is degenerate, meaning that most amino acids are encoded by more than one codon, providing redundancy in the code. This feature allows for some level of error tolerance during the translation process, as some mutations may not lead to changes in the final protein structure.

In summary, the genetic code allows each amino acid to be coded for by multiple codons, enhancing the versatility and robustness of the system.

Therefore, option B is correct.

The given statement is False. Incomplete dominance is a genetic phenomenon where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.

Incomplete dominance is a concept in genetics where neither allele in a heterozygous individual completely dominates or masks the expression of the other. Instead, the heterozygous phenotype exhibits a blend or combination of the traits associated with each allele.

This means that the traits expressed by each allele do not modify each other, but rather coexist in an intermediate form. For example, in the case of flower color, where one allele results in red flowers and the other allele in white flowers, the heterozygous genotype would result in pink flowers, representing an intermediate phenotype between red and white.

Answer:

The yeast die at 140° F

Explanation:

The fermentation process is caused by the living organisms called yeast feeding on the sugar in the dough. As the yeast feed on the sugar they release CO² which causes the bread to rise but once the bread in the oven reaches 140° all the yeast are killed off and the fermentation process stops.

The process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

Fermentation may be defined as a process a chemical process by which molecules such as glucose are broken down anaerobically in the presence of yeast.

During fermentation, the yeast produces excess carbon dioxide due to which the dough of bread swells. But after the completion of fermentation when bread places in the oven or any other warmer temperature, it killed the yeast, and hence fermentation stops.

Therefore, the process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

Answer:

B

Explanation:

The more the soil absorbs water the less space there is for the soil to absorb more therefore it runs off.

The thing that usually causes surface runoff is soil infiltration reaches capacity. The correct option is B.

The conveyance of water across the soil surface toward the stream channel is referred to as surface runoff.

Interflow is the relatively rapid movement of water beneath the soil surface toward the stream channel, usually within 72 hours of water infiltration.

Surface runoff occurs when the rate of precipitation exceeds the rate of infiltration. Because the air is saturated with water, evaporation returns water to the atmosphere but is negligible during rain events (when most of the surface runoff occurs).

When there is more water than the land can absorb, surface runoff occurs.

The excess liquid runs across the land's surface and into nearby creeks, streams, or ponds.

Surface runoff can be caused by both natural and human processes. Snowmelt is the most well-known type of natural surface runoff.

Thus, the correct option is B.

This phenomenon is known as independent assortment and it occurs during meiosis, the process of cell division that results in the formation of gametes in sexually reproducing organisms.

During meiosis, homologous chromosomes, which are pairs of chromosomes that contain the same genes, separate from each other and randomly sort into different gametes. This means that the chromosome inherited from either the father or the mother can sort into any gamete.

As a result, each gamete will contain a unique combination of chromosomes, leading to the potential for tremendous genetic variation in offspring.

This variation is essential for the process of evolution, as it provides the genetic diversity necessary for populations to adapt to changing environments and improve their chances of survival.
