Which region of the brain exhibits somatotopy?

A) primary somatosensory cortex

B) limbic system

C) hypothalamus

D) Broca's area

Answers

Answer 1

Answer:

A) primary somatosensory cortex exhibits somatotopy.

Somatotopy refers to the organization of the primary somatosensory cortex (located in the parietal lobe of the brain) in which it is mapped out according to the different areas of the body. Every part of the somatosensory cortex corresponds to a specific part of the body. This means that when a particular region of the body is stimulated (e.g. through touch), the corresponding region of the brain is also stimulated, which allows the brain to perceive the location and nature of the stimulus. This topographical organization of the brain is important in processing and integrating sensory information, and it is essential for motor planning, movement, and sensory perception.

Answers

The dissolution of copper sulfate in water is a physical change where as that of granulated zinc in dilute hydrochloric acid is a Chemical Change.

when CuSO4dissolved in water, no chemical reaction takes place since no new substance is getting formed.Thus it is a physical change. The dissolution of Zinc granules in dil. HCl is a chemical change because zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas is liberated.

Pseudoscience is based on empirical evidence, while science is based on observation and experimentation. C. Scientific claims are biased, while pseudoscientific claims are unbiased. O D. Scientific claims can be verified through observation and experimentation, while pseudoscientific claims cannot SUBMIT

Answers

Explanation:

The difference between science and pseudoscience is that science relies on experimentation and data gathered.

Pseudoscience is based solely on one's opinion rather than fact. in the early 1800's, scientists used to speculate what type of a person you are or intelligence by the shape of your head.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).

5. Which fur color seems to have the greatest overall selective advantage?
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.

Answers

Answer:

1)

frequencies of light-colored mice  ≅ 0.74frequencies of dark-colored mice ≅ 0.26

2)

frequencies of light-colored mice ≅ 0.13frequencies of dark-colored mice ≅ 0.87

3)

q² = 0.74p² = 0.02 2pq = 0.24      

4)

q² = 0.13p² = 0.42pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Answers

I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.

Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.

In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

binomial nomenclature

Explanation:

Binomial nomenclature as the name implies (binomial = two, nomenclature = naming) is a system of naming organisms that comprises of two unique Latin word names. The binomial nomenclature is a system of naming that was proposed by the man referred to as the FATHER OF TAXONOMY, CAROLUS LINNAEUS.

According to this system of naming organisms, the two names are the generic and specific epithet of the organism respectively. For example, in dog, which is Canis familiaris, Canis is the generic name while familiaris is the specific name.

b. Blood glucose increases to normal.
c. Liver breaks down glycogen and releases glucose to the blood.
d. Liver takes up glucose and stores it as glycogen.
e. Pancreas releases glucagon.
f. Body cells take up more glucose.

Answers

Answer:

c. Liver breaks down glycogen and releases glucose to the blood.

Explanation:

Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.

A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.

Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.

Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.
