The brain is divided into lobes that carry out different kinds of functions. There are 5 lobes in the brain:

1. Frontal lobe: Concentration, planning, problem solving, etc are the function performed by this region of the human brain.

2. Parietal lobe: Touch, pressure, taste and body awareness is processed by this lobe.

3. Temporal lobe: Long-term memory, hearing, emotions are processed in this lobe.

4. Occipital lobe: Sight is processed in this lobe.

5. Cerebellum: Coordination and balance, fine motor control are performed by this part of the brain.

The modern neuroscience has also confirmed the presence of brain waves like the alpha, beta, theta and gamma rhythm that sweep across the different lobes and regions of the brain. These waves are known to result from the collective activity of neurons in each of the regions. The brain waves are studied to check the activity of the regions that are coordinating together to carry out a particular type of task.

Use the picture to summarize the difference between the daughter cells that result from mitosis and meiosis.

Ugo [173]

Answer: Mitosis results in two diploid cells that have the same genetic makeup. Meiosis results in four haploid cells that are all genetically different from each other.

Which of the following is not a characteristic of Arthropods that has attributed to their diversity and success?

stiv31 [10]

<span>A. endoskeleton

</span>Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.

Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.

***HELP*** What is the role of a keystone species?

kumpel [21]

Answer:

<h2>D. Competitively dominant to other organisms in the ecosystem</h2>

A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether.

The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucose transport. E

Gekata [30.6K]

Answer:

Prediction is correct.

Explanation:

In the body, transportation of molecules can occur in different ways or mechanism.

An example is by facilitated diffusion.

It is a passive form of transport where carrier proteins shuttle the molecule such as glucose into the cell without using energy.

Glucose being a large molecule is shuttled by glucose carriers across the cell membrane into the cell by facilitated diffusion.

Therefore an increase in the number of glucose carrier means an increase in the rate of glucose transport.

The results will show our prediction was correct.

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.
