Answer:

Photosynthesis is defined as the process in which the chlorophyll-containing plant

cells synthesise food in the form of carbohydrates, using carbon dioxide and water

in the presence of solar energy.

Sources of raw materials required for photosynthesis:

(a) Water is taken in from the roots of the plant and is transported to the leaves.

(b) Carbon dioxide from the air enters the leaves through the tiny pores called

stomata .

(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is

used to synthesise (prepare) food from carbon dioxide and water.

Thus, photosynthesis can be represented by the following equation.

Different heights of grass are grazed by bison, creating areas for birds to build their nests. Moreover, they create wallows—ground depressions—where they roll around and compact the dirt.

Native Americans learned to rely on bison for a variety of needs, including food, clothing, housing, and religious observance. They used practically all of the creature, including the horns, flesh, and hair from the tail. Native Indians acquired the ability to ride horses by the 1800s, greatly increasing their hunting territory.

Both large and small spatial scales are affected by bison's effects, which include: enhanced grassland heterogeneity, nutrient redistribution, modifications to the diversity of plant species, creation and maintenance of grasses, productivity improvements in grasslands, competitive pressure with the other herbivores, modification of forest fires,

Explanation:

During prophase, the parent cell will have 48 chromatids. This is because during interphase, the DNA replicates, resulting in each chromosome consisting of two sister chromatids.

Therefore, if the parent cell has 24 chromosomes, it will have a total of 48 chromatids during prophase.

Regarding the major difference between plant cells and animal cells, the most accurate statement is: "Only plant cells have a cell wall." Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection to the cell. Animal cells, on the other hand, do not have a cell wall.

Chromosomes are coiled structures of DNA and proteins found in the nucleus of cells.

They carry genetic information and consist of genes that determine specific traits.

Bands on chromosomes are visible when stained and viewed under a microscope. These bands appear as alternating light and dark regions.

Each band contains multiple genes, and their unique locations help distinguish between different chromosomes.

Differences in banding patterns reflect genetic variations between chromosomes. These variations indicate the presence or absence of specific genes on a particular chromosome.

Chromosome banding is a laboratory technique that involves staining chromosomes with dyes.

This technique allows for the visualization of unique banding patterns on each chromosome. It is useful in detecting chromosomal abnormalities associated with genetic disorders.

By analyzing banding patterns, scientists can gain insights into genetic diversity, inherited traits, and the identification of genetic diseases such as Down syndrome, Turner syndrome, and Klinefelter syndrome.

Chromosome banding provides a valuable tool for studying the genetics of organisms and understanding the role of genes in various biological processes.

Precipitation involves the formation of a new solid substance from a solution, while agglutination involves the clumping together of particles without the formation of a new substance.

Precipitation and agglutination are two different processes in biochemistry.

Precipitation is the process in which a solid substance is formed from a solution due to a chemical reaction.

The solid substance (precipitate) forms as a result of the formation of an insoluble compound from two or more soluble components.

Agglutination, on the other hand, is a process in which particles (such as red blood cells, bacteria, or viruses) clump together.

This can occur as a result of a reaction with a specific antibody or other substance. In agglutination, particles are brought together and joined without the formation of a new substance.

Green Algae are placed in the Protista while plants are placed in a separate kingdom because Plants enclose and protect the embryo within the seed, while green algae do not.

Algae are difficult to define. Difficulty in classifying algae is determining whether they are Protista, plants, or whether they merit their own kingdom. Different classification systems answer this question in different ways, with some even splitting the group between the kingdoms Protista and Plantae.

Green algae can be either unicellular or multicellular. They live mostly in fresh water, but some can live on land in moist soils. A few green algae are found in marine environments. These organisms often live symbiotically with aquatic and marine animals. They are of particular interest because the group from which land plants evolved, the charophyta, are green algae.

The green algae are often classified in the Kingdom Plantae, based on two characteristics shared with higher plants:

This second characteristic indicates that the chloroplasts evolved from endosymbiosis of a prokaryote, as is the case with higher plants. Also, analysis of genetic material indicates a high degree of relatedness between green algae and terrestrial plants.

Haploid spores give rise to a multicellular haploid leaf-like structure called a thallus. The thallus produces gametes. Green algae are isogamus, meaning they have only one type of gamete, rather than having separate male and female gametes. When two gametes meet, fertilization takes place and a diploid zygote is formed. The zygote then germinates, undergoes meiosis and forms haploid spores. The diploid phase of the life cycle is brief and unicellular. There are a few exceptions this general life cycle, such as the Ulva (sea lettuce), which has a multicellular diploid phase similar to that found in brown algae.

8.multiple alleles

9.incomplete dominance

Explanation:

because i did it in savvas and i got it right.

The phenotype of an organism is influenced by the interactions of several genes. This implies that the organism's physical traits are governed by the interplay of several genes that it received from its parents.

When two alleles, or gene forms, are dominant, the dominant allele determines the phenotype of the progeny. This means that even if the other gene is recessive, the progeny will exhibit both traits if one of the alleles is dominant.

Sometimes a gene can take on several forms, producing more than two phenotypes. It is referred to as polygenic inheritance when more than one allele of a single gene affects the phenotype. Other times, two alleles are neither fully dominant nor fully recessive.

Students take part in this "alcohol gun" experiment to see what happens when an electric spark ignites ethanol vapor and air in a corked plastic bottle. The subsequent minor blast fires the plug across the room.

Liquor dissipates in light of the fact that, at a superficial, the particles of liquor interact with air. Vapor pressure, causes the liquid molecules at the surface to react and break their bond with hydrogen, causing it to begin evaporating. Alcohol has a rate of evaporation that is even faster than that of water.

When you start blowing on your hand, the alcohol and water will start to evaporate. Alcohol evaporates at a lower temperature than water does. That truly intends that for a similar measure of fluid, a more intense move happens during the dissipation of water contrasted and the liquor.

Q- What experiment did the student conduct that involved the evaporation of alcohol?

If the extracellular K+ concentration is increased, the resting membrane potential of the cell will become more positive.

This is because K+ is a positively charged ion and is involved in maintaining the negative charge inside the cell. An increase in extracellular K+ concentration would result in a higher concentration gradient for K+ to move out of the cell, which would cause the membrane potential to become less negative.

Therefore, an increase in extracellular K+ concentration would depolarize the cell and make it more likely to fire an action potential.

Most phenotypic traits are complex due to polygenic inheritance and environmental influences.

Phenotypic traits often result from the combined effects of multiple genes (polygenic inheritance) and can be influenced by environmental factors. Punnett Squares, which illustrate single gene pair inheritance, are not suitable for capturing the complexity of such traits. Additionally, environmental factors can interact with genetic factors, leading to variations in trait expression.

To measure complex phenotypic traits, alternative approaches are used. Quantitative measurements, such as height or weight, provide precise numerical values. Statistical analysis helps identify patterns, correlations, and heritability estimates in populations. It involves studying large sample sizes and employing statistical models to understand the contributions of genetic and environmental factors.
