Answer:
The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that (Primer Section Key Terms O)
A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.
Explanation:
Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle´s contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase , increasing muscle´s force as well.
No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.
A major problem to understand and correct the problems with the San Joaquin Valley lack of tools and scientific data on valley fever.
- A. lack of scientific tools and data
<h3>What is valley fever?</h3>
The small town of Avenal, in the San Joaquin Valley, is most affected by an incurable disease known as 'valley fever'. Cases of an incurable disease called "valley fever", are multiplying at an alarming and surprising rate in the southwestern United States.
With this information, we can conclude that San Joaquin Valley, is best known for an incurable disease known as 'valley fever', where there is no scientific data that can explain.

The question is incomplete. The complete question is:
Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?
a) Incomplete dominance
b) Genetic recombination
c) Chimerism
d) Codominance
Answer:
d) codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
