Complete question:
In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

Your skin is an example of a nonspecific defense mechanism. Why is it called a nonspecific defense mechanism?
A. becuase it protects against any invader regardless of type
B. because it has to be 'alerted' that a foreign invader has been spotted
C. because it alerts the immune system when a foreign invader is spotted
D. because it protects against a specific type of pathogen
Answer:

Explanation:
what happens to a animal cell placed in a hypotonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
Explanation:
Hypotonic solution is a solution which, contains lesser solute concentration. If animal and plant cells are kept in a hypotonic solution then endosmosis will occur. Endosmosis is a process in which the water molecules move from outside of the cell of lower solute concentration to the inside of the cell of higher solute concentration through the cell membrane or cell wall. Due to endosmosis, both animal and plant cells will swell.

14. Kidneys are filters. As blood passes through the kidney, waste in the form of urine is
left behind. Tubes take the urine from the kidney to a storage bag called the bladder.
What can you conclude about blood leaving the kidney?
A. It moves to the bladder.
B. It has no water left in it.
C. It is ready to be used by the body.
D. It needs to have urine added to it
Answer:
D. It needs to have urine in it
Explanation:
They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule. The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.

If the amino acids glycine, alanine and valine were combined in one molecule, what would the molecule be called?
Answer:
A tripeptide
Explanation:
Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).

How does stimulus become a memory? stay safe god bless.
Memories will occur when specific groups of neurons have been reactivated. The stimulus results in any brain in a particular pattern of neuronal activity. Some neurons start to become active in either more or less a particular sequence. Retrieval Cue; a stimulus for remembering information.
Consider the following scenario:
A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations.
What is the main selective pressure in this scenario?
(1 point)
drought
leg length

There are two varieties in a population of squirrels: short tails and long tails. Long-tailed squirrels are better at jumping and balancing in trees. Scientists observe that over the span of 100 years, the proportion of the population with long tails increases from 10% to 60%. Which statement is most likely? (1 point)
The proportion of long-tailed squirrels may have increased due to increased food availability.
The proportion of short-tailed squirrels may have decreased due to decreased food availability.
The proportion of short-tailed squirrels may have decreased due to an increase in trees.
The proportion of long-tailed squirrels may have increased due to a decrease in trees.
1. What is the main selective pressure in this scenario?
fish population.
2. According to the question, option "A" is correct The proportion of long-tailed squirrels may have increased due to increased food availability.
What is selective pressure?In evolutionary theory, the effect on survival of a species of the sum of all elements, physical and behavioural, inherent and environmental especially as an inherited characteristic may marginally affect survival under the influence of these elements.
Thus, the option "D" and "A" is correct.

What enzyme deficiency in RBC leads to hemolytic anemia due to oxidative stress?
In some cases, massive destruction of red blood cells caused death. This drug-induced hemolytic anemia was shown 30 years later to be caused by a deficiency of glucose 6-phosphate dehydrogenase, the enzyme catalyzing the first step in the oxidative branch of the pentose phosphate pathway.
in short terms, glucose 6-phosphate dehydrogenase

What might happen to the Earth if human increase the amount of greenhouse gasses?
Explain your answer.''
Answer:
Greenhouse gas refers to any gaseous compound in the atmosphere that can absorb infrared radiation, thereby trapping heat and keeping it in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
Examples why greenhouse gases in the atmosphere:

plz can i get brainliest:)
Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

Provide one example of Mutualism.
You must explain: The two organisms, how they both benefit, and any other necessary information to explain their interaction.Immersive Reader
Answer:
Cattle and egret
Explanation:
Mutualism is a type of symbiotic relationship involving two organisms whose actions cause them to benefit from one another. In other words, both organisms do one another a favour, hence, the relationship is said to be MUTUAL.
- An example of a mutualistic relationship is that of CATTLE AND EGRET. Cattle gets infested by certain parasites like ticks and fleas, which feeds on their blood. Egrets are bird species that flock around cattle to feed on these insect parasites. This relationship is mutual because, egrets help the cattle get rid of their parasite problem (cattle benefits) while the cattle provides food for the egrets when they harbor these parasites on their body (egret benefits).

What process is occurring in this picture at B?
Answer:
Translation
Explanation:
Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.
The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.
Hence, according to this question, the process occuring at B according to this image is TRANSLATION.
