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.

name the four major groups in the plant kingdom and discuss the major evolutionary trends across the groups

Answers

Answer:

The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular. A vascular plant has tissues for transporting water or sap. Nonvascular plants do not.

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.

How can an organism's environment affect its traits?

Answers

First, I read that so incorrectly. Awkward.

An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

A forensics expert has obtained a sample of human blood from a crime scene. How can DNA fingerprinting be useful for identifying the person who left
the blood at the crime scene?

A by identifying the sequence of nucleotides in the DNA of blood cells
B. by comparing DNA from the blood cells with DNA from suspects
C. by identifying certain genetically controlled traits of suspects, such as eye shape and blood type
D. by comparing karyotypes made from blood cells at the crime scene and blood cells from suspects

Answers

Answer:

B - by comparing DNA from the blood cells with DNA from suspects!

Explanation:

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.

A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.

If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )

Hope this helps! :]

A forensics expert has obtained a sample of human blood from a crime scene, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

What is DNA fingerprinting?

DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles, and by analyzing the sequence of nucleotides in an individual's DNA, forensic scientists can create a DNA profile that is unique to that individual. So to identify the person who left the blood at the crime scene, forensic scientists would analyze the DNA in the blood sample and create a DNA profile, and then find out the criminal based on the DNA fingerprinting.

Hence, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

I think thats because small animals have small body that can hide in a safe place. Like example if small animals hide go down to the earth, and the meteorite hit the earth, they will safe down to the ground.

Not like larger animals, they can only hide up he surface and when the meteorites came, they died.

Also some small animals such as cockroaches have ability to adapt to changes.
