Before answering the question, you should know that exons/intron systemin the gene exists only in eukaryotes. A gene can have many exons with introns between them, but in RNA maturation, these exons will be joined together to form one RNA to code for one protein (There's no relation between exons number and how many proteins are formed).
In prokaryotes it is different there's no exons/introns, but their gene can be transcripted to a polycistronic RNA which can give after translation more than one proteins.
Answer:
recessive
Explanation:
A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.
Answer:
The options:
1. "We need to discourage him from wearing eyeglasses."
2. "We need to place objects in his impaired field of vision."
3. "We need to approach him from the impaired field of vision."
4. "We need to remind him to turn his head to scan the lost visual field."
The CORRECT ANSWER IS 4.
"We need to remind him to turn his head to scan the lost visual field."
Explanation:
Homonymous hemianopsia is defined as a depletion of half of an individual visual area.
The patient with homonymous hemianopsia needs to position objects in the unimpaired area of vision, with the need for the nurse to come closer to the patient from the unimpaired area.
The nurse gives an order to the patient to make a quick view of the environment to repress the visual depletion and involving patient enlightenment from the inner region of the unimpaired area of vision.
The nurse could recommend the aid of personal eyeglasses, if the need eyeglasses are present at that time.
Answer:
Yes.
Explanation:
Yes, plant is the organism that is capable of both photosynthesis and respiration at the same time because prepare food as well as generate energy from respiration process at the same time. Plants make their own food through the process of photosynthesis by using water and Carbondioxide gas while on the other hand, energy produces in the process of respiration by using of glucose and oxygen.
Answer: To help retain warmth throughout the winter, they also grow thicker, shaggier coats, which they shed in the spring when the weather becomes warm again.
Explanation: They want to stay warm.
