what is the probability that a mother with type O blood and a father with type AB blood will have a child with type B blood
Answer:
So, without being given any more information (like that another child is already A, B, or O) then there are 16 possible combinations that can be had, but only one of them is type O, so there’s a 6.25% chance the child could be O.

A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Why are niches important to
ecosystems?
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

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

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