Which of the following statements is true? (a) Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor so as to signal a target cell to change its behavior. (b) To function, all extracellular signal molecules must be transported by their receptor across the plasma membrane into the cytosol. (c) A cell-surface receptor capable of binding only one type of signal molecule can mediate only one kind of cell response. (d) Any foreign substance that binds to a receptor for a normal signal molecule will always induce the same response that is produced by that signal molecule on the same cell type.

Answers

Answer 1

Answer:

Its option 'A'.

Explanation:

extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor so as to signal a target cell to change its behavior.

For Example:

Acetylcholine acts at a GPCR on heart muscle to make the heart beat more slowly.

Answer 2

The following statements is true - (a) Extracellular signal molecules that are hydrophilic must bind to a cell-surface receptor so as to signal a target cell to change its behavior

Extracellular signals:

Signals that originate from outside a cell

physical agents like mechanical pressure, voltage, temperature, light, or chemical

These are hydrophobic signals that can not cross the cell membraneBind to the specific signal receptor to target cell in order to initiate changes in cell function.For instance, neurotransmitters are hydrophilic molecules that bind to cell surface receptors.As neurotransmitters are hydrophilic molecules, they are unable to cross the plasma membrane of their target cells.

Plants from the genus Solanum include such common vegetables as potatoes and eggplants. The many species include some plants native to tropical West Africa as well as closely related species native to tropical South America. What might you reasonably conclude?

Answers

Answer:

The plants from West Africa and South America were once together as one population.

Explanation:

This could be used as a source of proof for continental drift. When West Africa and South America were connected as one continent, known as Pangea, these two now existing plants were one species of plant in the genus Solanum. As the continents drifted apart the plants evolved separately on each continent according to their different environments. Now they are just closely related species as they have evolved more differences.

The application of evolutionary principles to the study of human variation: a. ​helped replace earlier views based solely on observed phenotypes. b. ​allowed scientists to divide the human species precisely into well-defined races. c. ​reinforced traditional views of races as fixed biological entities that do not change. d. ​has been of little value for understanding human variation. e. ​allowed scientists to ignore the adaptive significance of most traits.

Answers

Answer: Helped replace earlier views based solely on observed phenotypes.

Explanation:  Historically, physical differences such as skin color were used as the basis of racial classification due to differences in skin pigment being so noticeable.

This thinking can be traced back to before World War II, where most studies of human variation were solely based on the visual phenotypic variations. It was only in the second half of the twentieth century that we started looking at genetics and realized that we could not trace human evolution based on visual phenotypes observed,  but rather genetic heritages.

Final answer:

Applying evolutionary principles to the study of human variation has replaced views based solely on observed phenotypes and advanced our understanding of genetic diversity. The concept of 'race' as a fixed biological entity has been debunked, with more genetic variation existing within 'racial' categories than between them. Therefore, this application has not prompted a precise division of the human species into races or ignored the adaptive significance of traits.

Explanation:

The application of evolutionary principles to the study of human variation has indeed helped replace earlier views based solely on observed phenotypes (option a is correct). This is because contemporary biological anthropologists use an evolutionary perspective to understand how living organisms, including humans, thrive in different environments. Central to this is the idea of natural selection, which suggests that those organisms with characteristics better suited to their environment are more likely to survive and proliferate. This approach has facilitated a greater understanding of human genetic diversity.

However, the concept of 'race', traditionally seen as a fixed biological entity, has been largely debunked by this approach. Most scientists now agree that there is actually more genetic variation within a given 'racial' category than there is between different 'racial' categories (options b and c are incorrect). Therefore, the application of evolution to the study of human variation has not allowed scientists to divide the human species precisely into well-defined races, nor has it reinforced traditional views of races as unchanging.

Far from being of little value or allowing scientists to ignore the adaptive significance of traits (options d and e are incorrect), the evolutionary perspective has been crucial in advancing our understanding of human variation, adaptation and evolution.

One of the reasons why statins are effective in reducing the risk of cardiovascular disease is ______.
a. they increase the transport of cholesterol away from the liver
b. they reduce the protein content of LDLs
c. they decrease the incidence of cholesterol deposition in arterial walls
d. All of the listed responses are correct.

Answers

Answer: c. they decrease the incidence of cholesterol deposition in arterial walls.  

Explanation:

The statin is a drug which block the action of the liver enzyme which controls the production of the cholesterol. The cholesterol is a biomolecule which aggregate inside the blood vessels such as arteries may lead to arteriosclerosis. This condition will lead to increase in blood pressure which may lead to the condition of hypertension or heart attack.

By lowering the levels of the cholesterol in the arteries the statins can reduce the risk of cardiovascular disease.  

Answer:

The correct answer will be option D.

Explanation:

Statins are a class of drug provided in the medication to treat cardiovascular disease.

Statins act by reducing the amount of bad cholesterol called low-density lipoprotein (LDL) from blood, preventing the formation of cholesterol from the liver by blocking the enzyme and pathway of cholestrol synthesis and the degradation of the deposited cholestrol form the arterial walls which make the arteries narrow.

Thus, option D is the correct answer.

You have an F2 generation derived from two true-breeding parents with different characteristics for the same trait (determined by two alleles of a single gene). What percentage of the F2 generation with a dominant phenotype would you expect to be homozygous for the allele of interest? (Hint: the parental cross results in the F1 generation. Two F1s are crossed to get the F2 generation.)

Answers

Answer:

The percentage for the homozygous dominant trait would be 25%. in the F2 generation.

Explanation:

Suppose true-breeding parents with the different alleles for the same trait are TT (dominant) and tt (recessive) than the cross of these parents will produce gametes T, T and t, t respectively.

These gametes will form offspring ultimately. Produced offspring will be TT (homozygous dominant), Tt (heterozygous dominant), Tt (heterozygous dominant) and tt (homozygous recessive).

Thus, the percentage of dominant homozygous phenotype in F2 would be 25% in respect of the dominant allele which is TT.

The percentage of the F2 generation with a dominant phenotype that would be expected to be homzygous for the allele of interest would be 33.33%

Let us assume that the allele of interest is A, the alternate form would be a.

Starting with true-breeding parents of different characteristics of the same trait:

                          AA   x    aa

                      Aa   Aa   Aa   Aa

All the F1 offspring would be Aa.

Advancing the cross to F2:

                     Aa    x   Aa

                  AA   Aa   Aa   aa

3/4 (AA and 2Aa) of the F2 offspring are with the dominant phenotype. However, only 1 out of the offspring is homzygous.

Thus, if the total of the F2 offspring with the dominant phenotype is 100%, the percentage with homzygous alleles can be calculated as:

                1/3 x 100% = 33.33%

(A) Yellow seed color is dominant over green.
(B) only yellow-green seeds
(C) green seeds:yellow seeds 1:3
(D) yellow seeds:green 1 : 1
(E) only yellow seeds

Answers

Answer:

Option E, only yellow seeds

Explanation:

True breeding means when the genotype of one parent consists of two identical alleles.

Let allele for green color seed be represented by "g" and yellow color seed be represented by "G"

In this scenario,

Genotype of true-breeding parents with green seeds is "gg"

Genotype of true-breeding parents with yellow seeds is "GG"

It is given that Yellow seed color is dominant over green

The punnet square representing this cross would be

G G

g Gg Gg

g Gg Gg

All the offspring are heterogyzous yellow seeded plants

How does the egg of a flower become fertilized? 1 answer, not multiple choice.

as soon as the pollen reaches the stigma
after the pollen grain descends down the style
when the pollen tube grows into the ovule
when the seed germinates

Answers

Answer:

as soon as the pollen reaches the stigma

Explanation:

When pollen lands on stigma, it germinates and gives rise to a pollen tube that passes through the style and reaches the ovary of a pistil

Answer:

when the pollen tube grows into the ovule

Explanation:

Fertilization in plants occurs after pollination.  Pollination does not always guarantee fertilization. Whether fertilization will occur or not totally depends upon the later stages which occur after pollination.

The following stages give a better idea of how egg of flower is fertilized:

1) Pollination: A soon as a pollen reaches the stigma pollination is said to occur.

2) Germination: When pollen comes in contact with stigma, it absorbs some chemicals like inositol, Ca²⁺, boran, brassinosteroids  and water from the stigma as a result of which pollen starts to increase in size to form pollen tube. The pollen tube begins to grow which is also known as germination.

3) Penetration of ovule & 4) Fertilization: The growing pollen tube travels through style to reach ovary which has ovule inside it. The pollen contains 2 haploid nuclei while ovule contains 3 haploid nuclei. One of the nuclei in ovule is in the egg cell so it is haploid while 2 nuclei are inside central cell. When the pollen tube keeps on increasing in size, it ultimately penetrates the ovule and one of the nuclei of pollen tube fuses with egg cell and the process is known as fertilization.The other nuclei of pollen tube fuses with central cell which ultimately has 3 nuclei and the process is known as triple fusion. These two processes i.e. fertilization & triple fusion are collectively known as double fertilization.

Dr. Tylka is conducting research about the risk of developing eating disorders in adolescent boys. She concludes that her findings apply not only to the sample of high school boys she studied, but to other males in other settings and contexts. In this regard, Dr. Tylka is stating that her findings have high __________ validity.

Answers

Answer: External validity.

Explanation:

When any research is done, then there are two possibility of its validation. One is internal validation and other is external validation.

The internal validation refers to the condition in which the conclusion of the study is within context of the particular study.

The external validation refers to the condition in which the conclusion of the study is out of the  context.

Here, The study was performed only on the eating disorders in the adolescent boys but the conclusion included other males of different age groups.

Final answer:

Dr. Tylka's conclusion that her research findings on the risk of developing eating disorders in adolescent boys can be generalized to other contexts indicates she believes her findings have high external validity.

Explanation:

Dr. Tylka is stating that her findings have high external validity. This term refers to the extent to which the conclusions drawn from a particular study can be generalized, or extended, to other settings, populations, or times. The generalizability of a study's results is an important aspect of its external validity. It relies on the use of valid survey questions which accurately measure what they are intended to measure, and reliable survey questions that consistently produce similar results across different instances to ensure a lack of bias.

Dr. Tylka's confidence in her research suggests that she believes her study's constructs and their measurement methods, including the survey questions, have been well designed to accurately represent and assess the risk of developing eating disorders among adolescent boys. This assurance further implies that these methodological tools are likely to yield similar findings if used in different contexts, which strengthens the claim of high external validity.

The neuromuscular junction is a well-studied example of a chemical synapse. Which of the following statements describes a critical event that occurs at the neuromuscular junction?

a) Acetylcholine is released by axon terminals of the motor neuron.
b) When the action potential reaches the end of the axon terminal, voltage-gated sodium channels open and sodium ions diffuse into the terminal.
c) Acetylcholine binds to its receptor in the junctional folds of the sarcolemma. Its receptor is linked to a G protein.
d) Acetylcholine is released and moves across the synaptic cleft bound to a transport protein.

Answers

Answer:

A- Acetylcholine is released by axon terminals of the motor neuron.

Explanation:

The general mechanism of muscle contraction can be explained as follows:

a) The action potential which is generated, travels along the motor nerve to its ends on muscle fiber (or motor end plate) at the neuro-muscular junction.

b) The nerve endings then secrete small amounts of neurotransmitter called acetylcholine.

c) The actylecholine binds to the receptors on the membrane of muscle fiber and opens the voltage gated sodium channels.

d) Opening of these channels leads to flow of large quantities of sodium ions into the muscle fiber which ultimately results in initiation of action potential in muscle fiber.  

e) This action potential depolarizes the fiber including the T-tubules, triggering the release of calcium ions from sarcoplasmic reticulum.

f) The calcium ions thus released initiated the process of muscle contraction.

Which of the following is the correct sequence of development from zygote to embryo?

cleavage, gastrula, morula, blastocyst
blastocyst, cleavage, gastrula, morula
cleavage, blastocyst, morula, gastrula
cleavage, morula, blastocyst, gastrula

Answers

Answer:

Cleavage, morula, blastocyst, gastrula

Explanation:

The zygote is formed after fertilization of sperm and ovum. Then the zygote undergoes a repeated cell division to form a number of cells. These tiny cells formed by mitotic cell division but present inside the zygote. It forms 2 cells then 2 cells, then 8 cells and so on. After forming the number of cells the zygote has a number of tiny cells. This stage is called morula and the tiny cells are called morulae. Then these cells migrate towards the periphery of the morula and creating a central space called blastocoel. This hollow ball structure is known as the blastocyst. After this blastocyst stage, the cells migrate to form 3 layers such as endoderm, mesoderm, ectoderm. From this layer different organs are formed. This 3 layered stage is known as gastrula. Thus the zygote development starts from cleavage, morula, blastula, and gastrula.

Final answer:

The correct developmental order from a zygote to an embryo is cleavage, morula, blastocyst, and gastrula, which involves cell division and restructuring into layers.

Explanation:

The correct sequence of development from a zygote to an embryo is as follows: cleavage, morula, blastocyst, gastrula. Initially, the zygote undergoes rapid cell division known as cleavage, forming smaller cells called blastomeres. This process leads to the formation of a morula, which is a solid ball of cells.

Following this, the structure develops into a blastocyst, which has a distinct inner cell mass and is surrounded by an outer layer of cells.

Finally, gastrulation occurs, where the blastocyst reorganizes into a gastrula with different layers that will develop into various tissues and organs of the embryo.
