Describe two effects that ingesting microbeads has on aquatic organisms.

Answers

Answer 1

Answer:

micro-beads can cause blockages in the digestive tracts of aquatic organisms.

  This can prevent digestion of food hence the organism will eventually die of starvation.

micro-beads can increase organic matter in a pond hence killing the aquatic organisms present.

  This increases the number of decomposers which grow rapidly and use a great deal of oxygen during their growth and lead to depletion of oxygen as the decomposition process occurs. A lack of oxygen can kill aquatic organisms.

Geneticists have been working for years to develop higher quality cotton fibers by selectively breeding plants with better fibers. What is a drawback of this selective breeding process?

Answers

We can confirm that the drawbacks of selective breeding include increased risk of genetic defects and reduced resistance to immunological threats.

What is selective breeding?

This is a breeding method in which specific organisms are bred that contain the desired trait, in order to produce offspring with that specific trait. This brings many downsides in that it reduces genetic variation in the organism, making it more prone to infections and disease, as well as increasing the risk of transmitting a genetic anomaly between breeding cycles.

Therefore, we can confirm that the drawbacks of selective breeding include increased risk of genetic defects and reduced resistance to immunological threats.

In scenarios 2 and 3, the simulation settings are such that it takes 30 days to run the vaccination campaign and 14 days to develop immunity. Explain the logic behind these setting choices. Hint: there are two reasons, one is biological and one is logistical.

Answers

The two possible reasons for these setting choices are that it takes to the body around 14 days to develop immunity and that vaccinating a lot of people is logistically demanding.

What are vaccines?

Vaccines are biological substances that help the body develop immunity against a virus, bacteria, etc. This is possible because vaccines contained a weakened or modified version of the pathogen that would help the body secrete specific antibodies for the real pathogen.

What is the possible reason for the 14-day setting?

Immunity does not occur immediately, indeed, it takes the body up to 14 days to build up immunity. This includes the modern vaccines.

What is the possible reason for the 30-day setting?

On the other hand, giving vaccines to large populations is quite demanding and challenging. Due to this programs with multiple weeks including four-week programs are ideal.

Water first-rate has significantly laid low with the presence of acid and base within the water. So answer is lake a: ph = 6.6; lake b: ph = 6.8.

The water isn't always precise for fitness whilst its exceptionally acidic or exceptionally basic. If the pH of water is almost impartial, this water is nice for consuming purpose. In the choice 3, each lake A and lake B has pH almost impartial so this water reasons no awful impact at the fitness of the human body. Highly acid water has low water first-rate because of the presence of metals which adversely have an effect on our body.

How does the mutation rate affect the speed at which a population adapts to its environment?

Answers

Answer:

Under these conditions an increase in the mutation rate evolves, which allows faster adaptation to the spatial variation in local temperature, causing a faster range expansion across the spatial gradient.

Answer:

The mutation rate is the speed (or mutations per unit time) at which a sequence of DNA changes, either through natural means or artificially induced means. Natural selection is the way that a population of organisms evolve over time to adapt to their environment.

If a strand of DNA has 48% cytosine what will the percent be for the other nitrogenous bases?

Answers

Answer:

There are 4 possible nucleotides that occur in two complementary sets. If 24% of the DNA is cytosin, the equal share has to be the complementary guanin. That makes 48% GC that leaves 52% AT, thus 26% are adenine and 26% thymine.

Why would it be incorrect to say that the DNA sequence A-C-G codes for the amino acid threonine?

Answers

It would be incorrect to say that the DNA sequence A-C-G codes for the amino acid threonine because mRNA codons code for amino acids not DNA.

What is a codon?

A codon is a triplet nucleotide sequence that encodes a particular amino acid.

A DNA sequence is transcribed into mRNA sequence, which is read in a group of three nucleotides called codon.

Each mRNA codon (three letter) encodes an amino acid.
