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.

1) Water is one of the required reactants for photosynthesis. It provides electrons that are energized by sunlight and used to make energy carriers like ATP. Where do plants get the water they need for
photosynthesis?
Answers
Answer: Plants get water from the soil their roots are embedded in.
Explanation: Photosynthesis can be defined as the process by which the the autotrophs make food with the help of carbon dioxide and water.Water provides electrons,these electrons are energized by sunlight and used to make ATP.The plants get water from the soil. The water in the soil is absorbed by the roots of the plant that is transported to the leaves for photosynthesis.hence, the answer is soil.

Answers
Answer:
7.5
Explanation:
Its neutral and testless
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.

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.

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.
This calculation of course wouldn’t work if you were to look at only one DNA strand, where you’d end up with a vastly underdetermined mathematical system.

What is meant by the term "osmosis"?
Answers
Answer:
Explanation:
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane. Any solvent can undergo the process of osmosis including gases and supercritical liquids.
Answer: in biology Osmosis is the carriage of a solvent through a semipermeable membrane that separates two solutions of differing solute concentration. During osmosis, the solvent moves from the solution so that lower in solute concentration to the solution that was highest in solute concentration.

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.
