<span>Women often cite alcohol abuse as a key cause or precipitating context of spousal abuse.
Huge intake of alcohol leads to intoxication. This clouds a person's judgment and inhibits proper mental functioning. Men would lose control and would violently abuse their spouses. </span>
Answer:
a. Rr, Rr
b. rr
c. 0% because its the women who transmits the disorder.
Explanation:
PKU allele is an autosomal recessive disorder which is caused by mutations in both alleles of gene for phenylalanine hydroxylase. Alleles are either dominant or recessive. When two alleles are identical means that mother and father cells are homoozygous recessive. They both are combining the same alleles causing it to have a higher chance of genetic disorder.
Answer:
a. Cell wall and chloroplasts
Explanation:
The cell wall in plants facilitates the retention of the cell shape during over-hydration. The chloroplasts are organelles in plants that carry-out photosynthesis and produce glucose.
Answer:
Mutations and Genetic Drift
Explanation:
A mutation refers to the random changes in the genome of the organisms. Being a random event, it is not possible to calculate the effect of mutations on the allele frequency of a population.
Genetic drift refers to changes in the allele frequency by chance event alone. Since the occurrence of chance events can not be predicted, the resultant changes in the allele frequency of the population can not be calculated.
The following are key characteristics of ape skulls that human skulls do not have:
(1) Prognathic Jaws: A chimpanzee’s maxilla (upper jaw) and mandible (lower jaw) protrude significantly. Typically, the bone from the nose to the tip of upper teeth extrudes out at about a 45 degree angle, whereas a line drawn from the nose to the chin of a typical human is vertical or concave.
(2) Large Brow Ridges above the eye sockets. Humans have negligible brow ridges.
(3) Absent or small laid back forehead: Apes lack significant vertical foreheads. Humans have large vertical foreheads, which provide room for the much larger frontal lobeof our brains. This is an important difference, as the large frontal lobe of the human brain allows us the ability to make decisions and solve problems. It also controls our behaviors, voluntary movements, emotions, and consciousness. Without a forehead, an animal would not have room for a large frontal lobe, and could not perform functions that differentiate animals from humans. The ability to make tools, improve on them, and the ability to remember how to make them, wouldn’t be possible without a forehead and large frontal lobe.
(4) Small Ovoid or Flat Cranium that houses their much smaller brains. Human adult craniums are about two to three times the volume of ape craniums. Ape craniums are narrower than the lateral extents of the eye sockets, whilst human craniums are far wider then the outer extend of their eye sockets.
