Compare biomes of North Africa and iceland

Travka [436]

Answer with Explanation:

"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.

The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.

Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."

Genetics Problems (ABO Blood System) The chart below lists the blood phenotypes of 8 individuals. Use the information in the cha

Setler79 [48]

Answer:

Explanation:

Female blood type Male blood type

Anne Type O Charlie Type A

Wendy Type B Scott Type AB

Susan Type AB Larry Type O

Patricia Type A Keith Type B

1. Larry has a son with type B blood. Which of the females listed above could be this child's biological mother?

For Larry that is of type O to produce a son with type B blood, his mother has to be either of type B or AB. Which is either Wendy or Susan

2. Anne is pregnant with Scott's child. What is the chance that the baby will have type A blood?

Since Scott possess the AB codominant type and Anne's type has to be inherited in the recessive form, the chances of producing type A is 50% and B is 50%. Thus, the chance that the baby will be of type A blood is 50%.

3. Because her daughter has type B blood, Patricia insists that Keith is the father. Keith claims that Scott is the father of Patricia's baby girl. Is it possible that Scott is the baby's father?

Since Scott that is of type AB is the father of a type B child, the mother Patricia that is of A type has to have a genotype that is AO for it to be possible that Scott is the father.

4. Keith and Wendy have a 4-year old with type O blood. How is this possible?

Keith is of type B blood and Wendy is also of type B blood. It is possible to have a 4-year old with type O blood if if both parents are of the BO genotype.

5. Susan is the mother of Charlie's first two children. The oldest, Dawn, has type AB blood while her sister, Kate, has type B blood. Charlie is now expecting a baby with Anne. What is the chance that this child will have type O blood?

Charlie and Susan can only produce Kate of type B blood if they are AO and AB respectively. Thus, since Charlie's genotype is AO, there is a 50% chance that he can produce a child of type O blood with Anne who is of type O blood.

6. Erin, Patricia and Larry's daughter, is married to Jeff. Jeff was in a serious car accident and needs a transfusion but Erin is told that Jeff cannot be given her blood. Based on this information, provide Erin's blood genotype and blood phenotype.

For Erin to be unable to give her blood to Jeff, it means Jeff is of O blood type and Erin is not, meaning she can either be A+, B+ or AB. But since her mother is of type A and father is of O, this rules out AB and also B. Her genotype can't be AA since her dad is of type O blood. Thus, it can be claimed that she is of genotype AO of type A blood type.

7. Scott and Susan's son, Paul, is willing to donate blood to a young girl with leukemia. If the recipient has type O blood, will Paul be able to donate to her?

Since the recipient has type O blood, she can only receive from a type O patient. Paul cannot be a donor because both parents are of AB blood type meaning Scott is either of type A, B or AB. Thus, he will not be able to donate as he is not of O type.

____ is an Inheritance pattern in which a tralt is controlled by many genes.

Ne4ueva [31]

Answer:

Eye colour

Explanation:

Eye colour is passed by your parents, what ever colour they have will determine what the child would have

If it was like two brown eyes the child would have brown eyes

If it was two different colours whatever colour which is more dominent will detirmen the colour of the child's eye

If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?

NNADVOKAT [17]

Answer:

<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.

Write a brief summary of the process of mitosis below.

fomenos

FULL ANSWER<span>The five main phases of mitosis are prophase, prometaphase, metaphase, anaphase and telophase. Some mitosis timelines include interphase, where the cell begins preparing to undergo mitosis. Prophase is the official start of mitosis, and during this step duplicated DNA strands condense into a more compact form and take on the traditional X shape of chromosomes.During prometaphase, the membrane around the cell's nucleus dissolves so that the chromosomes can move into place at the center of the cell. Spindle fibers align the chromosomes in the center of the nucleus during metaphase. This phase is essential to the health of the daughter cells, since it lines the chromosomes up evenly so they can be easily split in the next phase.Anaphase is the phase where two different cells start truly forming. The chromosomes are pulled apart, and half of each chromosome is pulled to separate ends of the cell, creating two bundles of chromosomes.In telophase, these bundles of chromosomes are enclosed in a new nuclear membrane. Once safely enclosed, the chromosomes break up again and lose their compact look. Finally, in cytokinesis the two sides break apart to create two new identical daughter cells.</span>
