The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of tectospinal, reticulospinal and vestibulospinal tracts.
The tectospinal tract in humans, also known as colliculospinal tract, is a nerve tract that coordinates head and eye movements. This tract is a part of the extrapyrimidal system in which it particularly connects the midbrain tectim and cervical regions of the spinal cord.
The vestibulospinal tract is a neural tract found in the central nervous system. It is specifically also a component of the extrapyramidal system and is a classified component of the medial pathway. The vestibulospinal fibers of the tract relay information from the nuclei to the motor neurons which is the same with the other descending motor pathways.
Lastly, the reticulospinal tracts or the descending or anterior reticulospinal tracts are extrapyrimidal motor tracts that goes down from the reticular formation in two tracts to act on the motor neurons supplying the trunk and the flexors and extensors of the proximal limb.
In order to find the percentage of the litters that will consist of two wavy- haired and three straight-haired offspring, you need to use the binomial distribution formula: P(x) = ⁿCₓ × pₓ × qⁿ⁻ˣ
P is the probability that the litters will consist of two wavy-haired and three straight-haired offspring.
X is considered to be the number of times the offspring will have wavy-air in a litter of 5 offspring, which is 2.
n is the number of offspring per litter.
p is the probability of happening wavy hair.
q is the probability of having straight hair.
It comes like this:
P(X=2)=⁵C₂×0.5²×0.5⁵⁻² ⇔ P(X=2)=10×0.25×0.125 ⇔ P(X=2)=0.3125
So, the percentage of the litters that will consist of two wavy-haired and three straight-haired offspring is 31.25%.
Answer:
Plants can be used to make materials.
Explanation:
Plants are important living organisms and they can be used in many ways. Some plants can be used as foods, some plants are used as raw materials for making medicines and other herbal products. Plants, such as cotton are used to make clothing materials and dead and decaying plants serves as fertilizer that add nutrients to the soil. Some other examples of a beneficial application of plants in human society would be that plants can be used for food. With that, they provide a very important source of nutrients for humans.
<span>B)The immunity they receive in the womb from their mother is temporary.
I believe this as the mother passes antibodies to the child through the last three months of pregnancy, and this is a passive immunity </span>
Answer:
"<em>Methane is a greenhouse gas, so its release would likely increase global warming."</em>
Explanation:
Methane is a greenhouse gas, so its release would likely increase global warming.
This is the only one that is both "true," and that applies to climate scientists.
Methane is toxic to marine organisms and would damage the ecosystem if released by killing species.
We are asking about <u><em>climate scientists.</em></u>
This would lead to massive pollution of drinking water.
We do not get drinking water from the ocean (except in some desert countries).
We want to extract and use this gas as a fuel source, but it would be lost to the environment through this process.
Again, climate scientists.
