MaRussiya [10]

Answer:

C) Platelets

Explanation:

Hemophilia is caused by a lack of clotting factors. Because platelets (or lack thereof) are what is responsible for how the blood clots, it can be reasonably inferred that the answer is C.

(Platelets secrete procoagualants, which are clotting factors. If there is a genetic issue with how these clotting factors work, then the platelets will not be useful.)

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

Electron microscopes use

Pavel [41]

Electron microscopes use _beam of electrons___ in order to allow for higher magnification and more detail when viewing specimens.

Explanation:

A beam of electrons has a shorter wavelength than normal light used in light microscopes, by approximately a factor of X 100000. Therefore, electrons microscope have the inherent attribute of having a very high resolution. They have been used to discover very small organelles in cells such as the ribosomes and mitochondria that cannot be clearly viewed even with the highest resolution in light microscopes.
