A chemist wants to show how the molecular structures of the major greenhouse-effect contributors allow them to
absorb heat.
Which of the following would the chemist not be modeling?
A) carbon dioxide
B) carbon monoxide
C) chlorofluorocarbons
D) nitrous oxide
E) methane gas

Answers

Answer:

Option C is the correct choice

Explanation:

The major contributor of green house effect are

a) Carbon dioxide (CO2)

b) Carbon Mono-oxide (CO)

c) Nitrous oxide

d) Methane

e) Ozone

The chlorofluorocarbons (CFCs) is a man made green house gas and hence the chemist will not model it as it does not allow to absorb heat. Instead it leads to non ending chain reactions with the ozone layer thereby degrading it and hence allow entry of harmful UV rays.

Option C is the correct choice

In addition to mutations, genetic variation can also arise during the formation of gametes during meiosis. During meiosis I, homologous chromosomes can randomly exchange segments, in a process called crossing-over. This trading changes the order of the genes in the DNA and on the chromosomes. Exchange material is integrated into the rest of the chromosomes DNA. Each chromosome loses some DNA and gains some DNA. As a result, there are more genotypes in the offspring. 2. What function does recombination by crossing-over have in genetic variation

Answers

Answer:

Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.

Explanation:

This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).

Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.

Bloodworms, which are the mature larvae of non-biting midge flies, are commonly found in and around bodies of water. Most types of bloodworms can live only in pollution-free, oxygen-rich environments. However, a few species thrive in environments with low concentrations of oxygen and high concentrations of nutrients and pollutants. From the changes in the bloodworm populations shown in the table above, what can be determined about how water in the stream has changed?
A. The water has become less polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.
B. The water has become more polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.
C. The water in the stream has become less nutrient-rich, as evidenced by the increase in bloodworm population density.
D. The water in the stream has become more oxygenated, as evidenced by the increase in bloodworm population density.

Which of the following is NOT a function of an antibiotic?
A. targeting the ribosome that inhibits protein synthesis, causing the cell to not function correctly
B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy
C. inhibiting the production of the cell wall and breaking down what is present

Answers

Answer:

B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy

Explanation:

Antibiotics can't attack on the mitochondria of the cell because mitochondria provides energy to the cell. Mitochondria is also known as power house of the cell means that it provides energy to the cell in order to continue its activities. If antibiotic attack on mitochondria of the cell, the cell has no energy for performing its activities that leads to cell death so that's why we can say that antibiotic can't attack on the mitochondria of the cell.

Answers

Answer:

B cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies).

Explanation:

T cells are a part of the immune system that focuses on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.

Answer:

T cells are responsible for cell-mediated immunity.

B cells are responsible for humoral immunity or antibody production

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

Answer:

The products of one process are the reactants of the other. Together, the two processes store and release energy in living organisms. The two processes also work together to recycle oxygen in Earth's atmosphere.
