Answer:

C is the correct option.

Explanation:

In the graph, we can see that the more lignin, the higher the height that the plant can reach, that is because lignin makes the plants more rigid and provides support.

This is related to the need for more support, which is also a difference among aquatic and terrestrial environments, because, outside the water, plants needed more support than inside of it. For example, algae outside the water would lie flat, in contrast to the vertical position they hold inside the water.

So, the presence of lignin was crucial for the evolution of land plants.

The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.

2 structures present in root hair cells are Cytoplasm and Cell membrane.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reactions. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth, and replication are carried out in the cytoplasm of a cell.

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Question;

Solution:

a) Remember that Diffusion is the process of random movement toward a

state of equilibrium. Now, In a solution without barriers, all the solutes diffuse at rates determined by temperature, their physical properties, and the concentration gradient of each solute. If a biological membrane divides the

solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The membrane is said to be permeable to solutes that can cross it more or less easily. In this case, we can see a process called simple diffusion, where small molecules pass through the lipid bilayer of the membrane. The more lipid-soluble the molecule, the more rapidly it diffuses through the bilayer. This statement holds true over a wide range of molecular weights.

Then, the correct answer to this item would be: diffusion.

b) One example of the process called difusion is when water molecules are abundant enough and small enough that they move through membranes by a diffusion process called osmosis. Now, we know that the difference in solute concentration between a cell and its surrounding environment determines whether water will move from the environment into the cell or out of the cell into the environment. For example, consider an animal cell. In a Hypotonic solution such as a dilute salt solution, water enters the cell, and cells swell and burst. On the other hand, if a Hypertonic solution such as concentrated salt solution, cells lose water and shrivel.

Then, the correct answer to this item would be:

The diffusion process can affect cells depending on the concentration of the extracellular fluid, for example, considering an animal cell, we get that :

1. In a Hypotonic extracellular fluid such as a dilute salt solution, water enters the cell, and cells swell and burst.

2. In a Hypertonic extracellular fluid such as concentrated salt solution, Cells lose water and shrivel.

Answer:

Climate and Weather: Some animals migrate to avoid extreme weather conditions, such as cold winters or dry seasons. By moving to more favorable climates, they can find suitable temperatures, avoid resource scarcity, or escape harsh environmental conditions.

Answer:

There are several reasons why some animals migrate while others are able to live in the same place year-round. One of the main reasons is related to the availability of resources such as food, water, and shelter. Animals that live in areas with a stable and predictable supply of resources may not need to migrate, while those that live in areas with seasonal changes in resource availability may need to move to find food and water.

Another factor that can influence migration is climate. Animals that are adapted to cold temperatures may migrate to warmer areas during the winter months, while those that are adapted to warmer temperatures may migrate to cooler areas during the summer months.

Genetics and evolution can also play a role in migration patterns. Some species have evolved to migrate as a way to avoid predators or to take advantage of seasonal changes in resource availability. Other species have evolved to stay in one place year-round and have developed adaptations that allow them to survive in their environment without the need to migrate.

Overall, the decision to migrate or stay in one place year-round is influenced by a complex interplay of environmental, genetic, and evolutionary factors.

Grafting is the process of attaching a piece of one plant (bud or scion) to or on top of a stem, root, or branch of another (stock) so that a union forms and the partners continue to develop. The component of the combo that supplies the root is known as the stock, and the additional component is known as the scion.

What about stock

In grafting, the stock refers to the lower portion of the plant that serves as the root system for the grafted plant. The stock is also known as the rootstock or the understock. It is usually chosen for its strong and vigorous root system and disease resistance

tRNA (transfer RNA) is a type of RNA molecule that plays a crucial role in protein synthesis. It carries amino acids to the ribosome, which is the site of protein synthesis, where the amino acids are joined together to form a protein chain.

If poison were to block our cell's ability to make tRNA, it would disrupt protein synthesis and affect the production of essential proteins in the body. This could lead to a range of symptoms, depending on the proteins that are affected.

For example, if the poison blocked the production of tRNA molecules that carry amino acids required for the formation of enzymes involved in digestion, it could lead to problems with digestion and absorption of nutrients. If the poison blocked the production of tRNA molecules that carry amino acids required for the formation of muscle proteins, it could lead to muscle weakness and atrophy.

In severe cases, such as if the poison blocked the production of tRNA molecules that carry amino acids required for the formation of essential proteins involved in the functioning of vital organs such as the heart or lungs, it could be fatal.

Rotate crops in the field the season before planting is the best IPM method to reduce bacteria count in the scenario given.

Integrated pest management (IPM) is a method of pest control that uses a combination of preventive, cultural, physical, biological, and chemical practices to reduce pest populations to an acceptable level. It is based on the idea that pests should be managed in a way that is less toxic to the environment and the people and animals living in it. IPM emphasizes the prevention of pests, rather than the use of chemical pesticides as the sole form of pest control. It also requires regular monitoring to assess the extent of the pest problem and to ensure that any control measures taken are effective.

Crop rotation is a type of agricultural technique where different types of crops are planted in the same area in a succession of growing seasons to optimize the soil quality and health over time. This means that different types of enriching crops can be planted in the same spot consecutively, resulting in healthier soil that is less prone to disease and nutrient depletion. Crop rotation also helps alleviate pest or weed problems, can improve water and air quality, and can promote biodiversity.

Explanation:

Archaea and eubacteria are primarily different in their genetic and biochemical characteristics.

While both archaea and eubacteria are single-celled microorganisms, they exhibit distinct differences in their genetic makeup, cell membrane structure, and metabolic processes. Here are some primary differences between the two:

1. Genetic Makeup: Archaea have unique genetic sequences that differ from both eubacteria and eukaryotes. They possess genes and genetic machinery that are distinct from other organisms, making them a separate domain of life.

2. Cell Membrane Composition: Archaea have cell membranes composed of unique lipids called isoprenoids, which are different from the fatty acid-based lipids found in eubacteria and eukaryotes. This structural difference allows archaea to thrive in extreme environments, such as hot springs and acidic environments.

3. Metabolic Processes: Archaea exhibit diverse metabolic pathways and can utilize a wide range of energy sources, including methane, sulfur, and even sunlight. Eubacteria, on the other hand, encompasses a broader range of metabolic diversity and can be found in various environments, including soil, water, and living organisms.

Regarding the second part of your statement, archaea and eubacteria are not considered ancestors of protists and first eukaryotes. The origin of eukaryotes is still an area of scientific inquiry and debate. However, current scientific understanding suggests that eukaryotes likely evolved from a symbiotic relationship between prokaryotic cells, including both archaea and eubacteria, giving rise to complex cellular structures and internal compartments. This process is known as endosymbiotic theory. Protists, which are a diverse group of eukaryotic microorganisms, likely evolved later in the course of evolution.

Answer: The organism will not produce the protein coded by the gene.

Explanation:

The effect that will the mutation have on the organism is the organism will not produce the protein coded by the gene. Thus, the correct option for this question is B.

A Mutation may be defined as the sudden, stable, and inheritable changes in the genetic material of organisms. The organism which undergoes mutation is known as a mutant. The agents of mutation are known as mutagens.

The Mutation leads to alterations in the genomic sequences of an organism. Due to this, the proteins formed are different compared to normal. The function of the previous protein is blocked and a new function is visualized.

So, if an organism has a mutation in a gene that blocks its function, the organism will definitely not be able to the protein coded by that gene.

Therefore, the organism will not produce the protein coded by the gene is the effect that will the mutation have on the organism. Thus, the correct option for this question is B.

Q1)When a substance is said to “dissolve” in water, it means that it is able to mix with the water molecules and form a homogeneous solution. This means that the substance is evenly distributed throughout the water and is no longer visible as a separate entity. Hydrophilic substances are able to dissolve in water because they have a strong affinity for water molecules, allowing them to form strong hydrogen bonds with them.

Q3)The hydrophilic head of the phospholipid is held in place by a combination of electrostatic and hydrogen bonding interactions with the hydrophobic tails. These interactions are strong enough to keep the head and tail together, even when the bilayer is subjected to mechanical forces.

The population is not in hardy weinberg equilibrium, because it does not match the previous generation.

The frequency of individuals = individuals/total population

The frequency of Green individuals = 1092/1200

The frequency of Green individuals = 0.91

                                                       q² = 0.91

                                                    √ q² = √0.91

                                                         q = 0.953

By using the first Hardy-Weinberg equation:

                                                                p + q   = 1

                                                                p + 0.953 = 1

                                                                p   = 1 - 0.953

                                                                p    = 0.046

No, "Crick and Watson" is not a type of genetic test. Crick and Watson refer to James D. Watson and Francis Crick, who were scientists involved in the discovery of the structure of DNA. They proposed the double-helix structure of DNA in 1953, which provided the foundation for understanding genetic information and its role in heredity.

Genetic tests, on the other hand, are laboratory tests that analyze an individual's DNA or genes to provide information about their genetic makeup, potential genetic disorders, or predispositions to certain conditions.

These tests can be used for various purposes, such as diagnosing genetic disorders, predicting the risk of developing certain diseases, determining carrier status for genetic conditions, or providing ancestry and genealogical information.
