Answer:
none, worms dont have eyes
Explanation:
Below are the questions:
A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?
<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g.

Below are the answers:
a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>
Answer:
Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants
Explanation:
Axon guidance is a neural development subfield relating to the mechanism by which neurons send out axons to meet their right targets.
ABL gene is a protooncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes. PTPs are known to signal a number of cellular processes, including cell development, differentiation, mitotic cycle, and oncogenic transformation.
Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants.
Answer:
A. BY, or YB
Explanation:
This question is depicting a phenomenon in inheritance called CODOMINANCE, which is a type of non-mendelian inheritance in which two alleles of a gene both express themselves in that gene. In this question, the allele for blue color (B) is codominant with the allele for yellow color (Y).
This means that an individual that has a blue phenotype will possess the genotype BB while an individual that has a yellow phenotype will possess the genotype YY. Hence, in an heterozygous state in which both alleles combine to produce a simultaneous blue and yellow phenotype, the genotype will be BY or YB.
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
