The polysaccharide that is responsible for the strong structural nature of plant cell walls is

Answers

Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant's life style. The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited. A cortical array of microtubules can determine the orientation of newly deposited cellulose microfibrils, which in turn determines directional cell expansion and therefore the final shape of the cell and, ultimately, of the plant as a whole.

The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.

The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.

The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.

Which of the following questions about genetic diversity could most appropriately be answered by an analysis of the model in Figure 1?
A) Does crossing-over generate more genetic diversity than the fusion of gametes does?

B) Does DNA methylation prevent independent assortment during metaphase II?

C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?

Answers

The answer is C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?

What is independent assortment?

Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.

This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.

What’s the correct mRNA sequence from the DNA strand: TAC GCC CGA ATC

B. AUG GCC GCU UAG

C. AUG CGG GCU UAG

D. AUG CCG GCT UAG

E. ATG CCG CGT TAG

Answers

Answer:

C. AUG CGG GCU UAG

Explanation:

This works the same as a normal DNA strand, A=T, C=G, except for one difference. Thymine is not an mRNA base, instead it is Uracil. Therefore, if there is an A, you would typically replace it with a T, but for mRNA you will replace it with a U. Keep in mind you will still replace the T in the DNA strand with an A in the mRNA strand :)

Over time, what will to happen to the populations of light and dark moths on light trees?

Answers

Answer:

Explanation:white moths will be spotted easier and killed and the population would drop while the dark moths population will rise

The population of white moths at the light tress will increase over time with the process of natural selection.

The trees are a light color population. Dark moths are unable to camouflage with the tress, while white moths camouflage with the trees.

What happens to white moths?

The white and black moths at the tree are an example of a tree ecosystem. The moths are the target for the predators.

The process of natural selection is the evolutionary process with the survival of the fittest. The species that are able to survive in the inappropriate conditions are able to evolve.

In the tree ecosystem, the white moths are camouflaged with the trees. They will not be an easy target for predators. They will survive with the theory of natural selection.

The black moths are not camouflaged with the tree ecosystem. They are easily identified by the predators and are killed.

Thus, white moths are the fittest and with natural selection, they evolve.

Therefore, the population of white moths at the light tress will increase with natural selection.

Answers

Answer:

phenotype or trait

Explanation: if it is really cold a mouse with thicker fur (phenotype) will do better

Environmental conditions often favor one selection over another.

In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.

For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.

Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.

Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.
