A student presents an argument as to the importance of lysosomes. Which of the
following statements would be a valid justification to support the student's argument?
A. Lysosomes are needed to digest biomolecules
B. Lysosomes are needed to store energy
C. Lysosomes are needed to package proteins
D. Lysosomes are needed to synthesize proteins

Answers

Answer 1

Answer:

A

Explanation:

Lysosomes break down cell parts when needed, and can self-destruct the cell. Organelles are made of biomolecules, the building blocks of life. Therefore, A is the answer. Hope it helps :)

g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome

Answers

Answer:

TEs are repetitive and mobile elements, thereby it is hard to trace their origins  

Explanation:

Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

The gram-negative bacterium Vibrio cholerae produces a protein, cholera toxin (Mr 90,000), that is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea. If body fluids and NaCl are not replaced, severe dehydration results; untreated, the disease is often fatal. When the cholera toxin gains access to the human intestinal tract it binds tightly to specific sites in the plasma membrane of the epithelial cells lining the small intestine, causing adenylyl cyclase to undergo prolonged activation (hours or days).

a. What is the effect of cholera toxin on [cAMP] in the intestinal cells? Why?
b. Based on the information above, suggest how cAMP normally functions in intestinal epithelial cells. Briefly justify.
c. Suggest a possible treatment for cholera

Answers

Answer:

a.) It causes prolonged activation of adenylyl cyclase which leads to increased levels of Cyclic adenosine monophosphate(cAMP).

b.) In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.

C.) Cholera can effectively be treated through the use of antibiotics and intravenous fluid replacement therapy.

Explanation:

Vibrio cholerae is a gram negative rigid curved bacillus that are actively ( vigorously) motion by a polar flagellation. The name vibrio is derived from the characteristic vibration movement of the organism when viewed under a microscope. This bacteria is capable of producing toxins called cholera toxin, which it uses as a virulent factor. It is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea.

Cyclic adenosine monophosphate(cAMP) which is called a second messenger because it is not a hormone that can directly institute an intracellular change, instead, it serves as a second messenger to cause an effect.In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.

In the effect of cholera toxin on the cAMP in the intestinal cells, Cholera toxin increases the fluid loss. The binding of the toxin to the intestinal cells causes a large increase in the level of cAMP in the cells by inhibiting the conversion of GTP bound to Ga to GDP. So adenyl cyclase is not turned off and diarrhea results.

The possible treatment is through the use of antibiotics and intravenous fluid replacement therapy. Prompt and adequate replacement of lost fluid and electrolyte through oral administration and supplemented with intravenous administration of fluids highly suggested for treatment of cholera. Antibiotics is equally used for treatment only when the cholera strain has been confirmed sensitive to it through culture.

Identify three immune system organs and their functions.

Answers

Answer:

Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes.

Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils, and certain tissue in various mucous membrane layers in the body (for instance in the bowel). It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.

Also...

Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone, and pelvis.

The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38

Answers

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

Ecological Succession: Transformation of Communities over Time

Why does secondary succession occur faster than primary succession?

Answers

Answer:

Because there is already presence of soil and nutrients in secondary succession

Explanation:

Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.

- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.

This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.

Answer:

Soil with nutrients is already present.  Seeds are present from earlier occupants, brought in by wind, and/or germinate after fire.
