Answer:
A. 0
Explanation:
Both red-green color blindness and and shape of hairline are independently assorting genes.
Red-green color blindness is X-linked recessive while hairline shape is autosomal dominant.
The man who has widow's peak had a father with straight hairline. This means that the man is heterozygous for the trait.
Assuming hairline shape is represented by S. A heterozygous widow's peak man will have a genotype of Ss. A straight hairline woman will have a genotype of ss.
Assuming the allele for colour blindness is c. A normal vision man will have the genotype 
while a color blind woman will have the genotype 
.
x 
<em>The man does not have the color blind allele and a daughter will need two color blind alleles (one from the father and the other from the mother) in order to show the trait.</em>
<em>This means that the probability of the couple producing a color blind daughter is 0. Hence, the chance that any daughter the couple has will be color blind with a straight hairline is also 0.</em>
The correct option is A.
Answer:
The correct answer will be-
1. Mobile elemests- LINEs and SINEs
2. Exons
3. Non-coding RNA genes
4. Introns
5. Repetitive DNA sequence
Explanation:
The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.
The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.
The non-coding sequence includes the Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.
Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.
Answer:
D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.
Explanation:
Glucose is a polar, large, and hydrophilic molecule that cannot easily diffuse the cell membrane. It moves across the membrane through a mechanism known as <u>facilitated diffusion</u>. In this process, a carrier protein attaches itself to glucose molecule and transport it without any use of ATP. Instead, the movement is driven by concentration gradient. An example is the diffusion of glucose in red blood cells.
B or C. Hypothesis being an estimated gas before starting and experiment . I’m sorry
Answer:
they have to remain small because nutrients go around faster around the cell then bigger cells
Explanation:
hopefully i explained it well
