Mountain range; when plates are pushed together, they cause rock to push up. After thousands of years, a mountain will be formed after the molten rock cools.
Answer:
The genotype of the F1 was wy+/w+y.
Explanation:
One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.
<u>We have two genes with two alleles each:</u>
Red eyes (w+) is dominant over white eyes (w).
Brown body (y+) is dominant over yellow body (y).
The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:
- wy+/ey (white-eye, brown body): 670
- w+y/wy (red-eye, yellow body): 650
- wy/wy (white-eye, yellow body): 38
- w+y+/wy (red-eye, brown body 56
If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).
Every individual in the offpsring has a <em>wy</em> chromosome, as this was the gamete inherited from the test cross individual.
In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.
Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.
One organic waste that is not found in urine is called Bicarbonate Ions
Answer:
The main function of the circulatory system is a To transport material throughout the body.
Explanation:
Blood in an important component of circulatory system.Blood contain Red blood cell that in turn contain hemoglobin which helps in the transport of oxygen and carbon dioxide to and from various body tissue.
The circulatory system also helps in the transport of nutrients such as glucose to various parts of our body such as heart,muscle,brain etc.The glucose molecules are utilized by those organs to perform their physiological functions.
The circulatory system also transport various hormone from the region of secretion to the target cell .
