Complete question:
Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (TT = 0.56; Tt = 0.28; tt = 0.16) and used to determine the actual allele frequencies in the population. Is this population in Hardy-Weinberg equilibrium? Calculate the T and t.
Answer:
No, the population is not in H-W equilibrium

O Pressure is higher than crust.
Answer:
D
Explanation:
I am taking the test
The statement describes the property of the asthenosphere, which is that the pressure is higher than the earth's crust.
What are the properties of the asthenosphere?The asthenosphere is the denser and weaker layer below the mantle of the lithosphere. It is approximately 100 kilometers (62 mi) and 10 kilometers (255 mi) below the Earth's surface.
The asthenosphere is the part of the upper mantle below the lithosphere that participates in plate tectonic movement and isostatic regulation. It consists of peridotite, a rock that mainly contains the minerals olivine and pyroxene.
The asthenosphere is the mechanically weak and flexible region of the Earth's upper mantle. It is located under the lithosphere, approximately 80-200 kilometers below the earth's surface and extends to a depth of 700 kilometers.

what are the sections on chromosomes? genes or DNA?
Answer:
genes
Explanation:dna whatttt
Answer:
Each section of a chromosome that contains the code for the production of a particular protein is called a gene . Each chromosome is made from a single molecule of DNA, but when a cell is ready to divide, the DNA copies itself, then coils and condenses to form the chromosomes that we see in micrographs .

Which of these transport processes is the major means by which Na+ is transported across the membrane of neurons? Why?
A) both II and III because the activity of the neuron varies
B) I because Na+ is so small it can freely diffuse into the cell
C) III because Na+ is actively transported out of a neuron to maintain extracellular concentration
D) II because Na+ is charged and cannot cross the hydrophobic interior space of the cell membrane
Answer:
i think it’s C
Explanation:
I. is diffusion
II. is facilitated diffusion
III. is active transport
the third diagram makes most sense to me
Transport processes is the major means by which Na+ is transported across the membrane of neurons,I because Na+ is so small it can freely diffuse into the cell.

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?
The trend in the corn productivity shows an increase from the year 1988 to 2008.
This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

How do heterotrophs make energy? How do autotrophs make energy?
Answer:
Heterotrophs obtain energy by eating plants and animals. Plants are autotrophs, absorbing the sun's energy through photosynthesis and making glucose. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

Reliability and probability in forensic tests are important. When you look at matching a paint chip to a specific car, you are working to increase the probability that the right car matching your paint chip evidence will be found. Reliability means you have practiced and applied the correct procedures and processes for all your evidence testing, and you know you can trust the results. Some forensic tests are more reliable than others, and the best type of test or tests to use will usually depend on the kind of evidence that is present. If all types of evidence were present at a crime scene, which type of test would you choose based on its reliability and probability of accuracy? Identify which test you would choose and provide a detailed argument as to why you feel it has a high level of reliability in comparison to other types of evidence. Your answer should be at least two paragraphs in length and should include solid arguments for your choice. There is no wrong choice, just be sure to provide a convincing argument.
