Answer:D
Explanation:
Multiple Sclerosis is an autoimmune disorder. Therefore, option (D) is correct.
What is multiple sclerosis?Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system. It occurs when the immune system mistakenly attacks and damages the myelin sheath, the protective covering of nerve fibers in the brain and spinal cord.
This leads to a range of symptoms that can vary greatly from person to person, including fatigue, vision problems, numbness, muscle weakness, and difficulty with coordination and balance.
The cause of MS is not yet fully understood, but it is believed to involve a combination of genetic and environmental factors. There is currently no cure for MS, but treatments are available to manage symptoms, slow the progression of the disease, and improve quality of life for those affected.

Muscle twitching can be explained by the temporal summation action of synapse. Thus, the correct option is B.
What is Muscle twitching?Muscle twitching is also called as muscle fasciculation. Muscle twitching involves a small muscle contraction in the body muscles. Muscle twitches are caused by the muscles tightening up or contracting involuntarily. In other words, it occurs when we are not actually controlling their actions. Muscle twitches can happen for a lot of reasons, such as stress, too much caffeine, a poor diet, exercise, or as a side effect of medicines.
Temporal summation is a physiological effect when the second muscle twitch becomes much higher than the first twitch, forming a tension in the muscle fiber. This happens because, after the first twitch of the muscle, the second stimulation is applied before the muscle even relaxes however both the stimuli are of equal strength.
Therefore, the correct option is B.

In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between two heterozygous shorthaired rabbits? I need you to fill out this chart I got the answer to the ratios
Answer:
Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
Both are heterozygous for the trait so we can expect that the cross would be:
Ss x Ss
S s
S SS Ss
s Ss ss
So the resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
So in summary:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair
ss 1/4 Long hair 1/4

Why are there less secondary consumers in an ecosystem than producers? (1 point)
There isn't enough energy available to support more secondary consumers.
Around 90% of energy from one trophic level to the next is available.
More tertiary consumers will eat secondary consumers over producers.
There is less land to use for habitat after the producers grow.
Answer: There isn’t enough energy available to support more secondary consumers.
Explanation:
There isn’t enough energy available to support more secondary consumers.
What are secondary consumers?Organisms that consume primary consumers for energy are known as secondary consumers. Herbivores, or species that only consume autotrophic plants, are always the main consumers.
Secondary consumers, however, might either be omnivores or carnivores. Omnivores consume both plant and animal stuff, while carnivores solely consume other creatures.
Secondary consumers can be found in almost every environment on earth and occur in a wide variety of sizes and shapes. The severe habitats that secondary consumers reside in include icy tundras, parched savannahs, and arctic lakes.
Therefore, There isn’t enough energy available to support more secondary consumers.

Maple trees and Saguaro cactuses both the plants grow in different climates. Thus, the correct option is b.
What are Maple trees and Saguaro cactuses?Most of the maple trees prefer to live in the cool temperature regions such as in the USDA plant hardiness zones 5 through 9, but a few of the cold-hardy maples can also tolerate sub-zero winters in the zone 3. In the regions of United States, zone 3 includes all the parts of South and North Dakota, Alaska, Minnesota, and Montana as well.
Saguaro cacti has the scientific name, Carnegiea gigantea. This plant only grows in the Sonoran Desert. However, they do not grow in all the parts of the Sonoran Desert. These plants are found in warmer climates generally.

After disrupting the CCR5 gene in the two macrophages cell lines 4 and 7 (now called edit 4 and edit 7), what will be your next experimental step to verify that these cell lines are now HIV-resistant macrophages?
Answer:
cell lines should be resistant to HIV infection, thereby preventing its integration into the host genome. In consequence, verification can be done by measuring intracellular HIV DNA declines (for example, by real-time quantitative PCR).
Explanation:
HIV (human immunodeficiency virus) is an RNA retrovirus that infects components of the human immune system including, among others, macrophage cells. After infection, the HIV genome is reverse transcribed into DNA and integrated into the genome of the host cells, thereby enabling virus to replicate its genetic material and synthesize protein viral components. Monocyte-like cell lines are able to differentiate into macrophages. When immune cell lines (both monocyte and macrophage cell lines) become resistant to this virus, HIV genome integration is inhibited, affecting the replication cycle of HIV. Thus, it is possible to verify that viral integration did not occur by measuring intracellular HIV DNA declines.
What happens if human cells contribute to the growth of a chimera brain? Should the chimera be considered a person
Answer:
No. it should be considered its kin (Kind) as a chimera
Explanation:
The reason why is because lets say we have a human. Totally normal and fine, but then there cell's get all jittery and there mind gets transformed. So then they start acting like a wolf, because the cells contributed to the growth of a wolf brain. They'd be considered a Were-Wolf then would be put in asylum to be studided and to keep humanity safe. So yes by law they are still a person. But in consideration, No they are not to be considered a person.
