Answer:
Genotypic and Phenotypic ratios → 1:1:1:1
- 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
- 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
- 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
- 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww
Explanation:
<u>Available data</u>:
- spotted skin (S) is dominant over non-spotted skin (s)
- wooly hair (W) is dominant over non-wooly hair (w)
- Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.
Parentals) Ssww x ssWw
Gametes) Sw, Sw, sw, sw
sW, sW, sw, sw
Punnett square) Sw Sw sw sw
sW SsWw SsWw ssWw ssWw
sW SsWw SsWw ssWw ssWw
sw Ssww Ssww ssww ssww
sw Ssww Ssww ssww ssww
F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.
Genotypic and Phenotypic ratios → 1:1:1:1
The role of a Detrivore is to help recycle the nutrients in the soil. They break down complex proteins, and other materials so the answer is A. to decompose dead animals.
The correct answer is c. 3 ' hydroxyl of deoxyribose.

During the DNA synthesis via PCR, polymerization occurs in 5’-3’ direction. This means that enzyme DNA polymerase which synthesizes a new DNA strand is complementary to the DNA template strand (3’-<span>5’ direction). 5’ phosphate group of the free nucleotides which are added is attached to the 3'-hydroxyl group at the end of the elongating DNA strand.</span></span>
The answer is A, water enters threw the roots not the leaves
The source of energy for Earth is our sun. Sir Issac Newton thought of
light as a steady stream of particles. His contemporary, Christian
Huygens, thought that light had a wave motion. They were both correct.
Light energy consists of moving quanta of photons. In 1802 the English
physicist Thomas Young confirmed hypothesis by proving that light
traveled in waves.

Photosynthesis is the major process by which wavelengths are converted
from light energy into a form of chemical energy which can be used by
living organisms. This conversion process will be studied later in the
semester. The energy from the sun is stored in the bonds that hold
molecules together.

One major storage source of this energy is the glucose which can be
produced as a by-product of photosynthesis. When glucose is broken apart
in the process of cellular respiration, it can be made available for
use by organisms in all metabolic activities. The level would be about
5,000.
