Answer:
The appropriate answer is D. Alfalfa. Alfalfa is a legume and these plants play a key role in the nitrogen cycle. These plants house nitrogen fixing bacteria on their roots. The bacteria are housed in tiny round structures of leguminous plant roots. Once the nitrogen is fixed in the soil it can now be used by other plants to make food. These plants include beans peas and peanuts

Explain how differentiation led to the development of a nerve cell from a fertilized egg. Then, explain how a nerve cell is specialized for cell communication.
Answer:
Explanation:
Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. ... Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals.
Which of the following is NOT a function of the muscular system?
A. movement B. stability C. temperature regulation D. calcium storage
Temperature regulation is not a function of the muscular system. Therefore, option (C) is correct.
What are the functions of muscular system?The strong framework is an organ framework, involved significantly in the development of the body. There are almost 700 muscles that are associated with the bones of the skeletal framework, which generally half make up the human's body weight.
It regulates posture, allows for body movement, and circulates blood throughout the body. In vertebrates, the nervous system is responsible for controlling the muscular systems, though some muscles.
Contractility is one of the most common features of skeletal muscle tissue, and muscle contraction is responsible for nearly all body movement.

The
contains granular cells composed of shrunken keratin fibers.
Stratum spinosum
Stratum basale
Stratum granulosum
Stratum corneum
The contains granular cells composed of shrunken keratin fibers is Stratum granulosum .
The stratum granulosum, which has three to five cell layers, has diamond-shaped cells with lamellar and keratohyalin granules. Keratin precursors are found in keratohyalin granules, where they eventually gather, crosslink, and form bundles.
Dense basophilic keratohyalin granules are accumulated by the cells of the stratum granulosum (SGR) (seen on the close-up view). Lipids found in these granules work with desmosomal connections to create a waterproof barrier that serves to stop fluid loss from the body.
The stratum granulosum normally has a thickness between one and 10 cells, similar to the stratum corneum. Compared to those in the stratum spinosum, keratinocytes in the stratum granulosum are flatter and have more erratic shapes. They also have deeply basophilic keratohyalin granules. Odland bodies, lamellar granules, and keratinosomes are also released by keratinocytes in the granular layer, and these substances help the stratum corneum's cells adhere to one another and form a permeability barrier to water. Keratinocytes prepare for the disintegration of their nucleus and other organelles as they develop and go higher to the stratum corneum.

Answer:
A healthy body functions best at an internal temperature of about 37°C (98.6°F). But everyone has their own individual "normal" body temperature, which may be slightly higher or lower. Our bodies also constantly adapt their temperature to environmental conditions. It goes up when we exercise, for instance.

their good sonar
their good eyesight
their large wingspans
The characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.
The characteristics of a golden eagle:The golden eagle is one of the most widespread eagle in the world.
That is because they are able to adapt in almost every type of climate, especially open areas with vegetation.
Some of the characteristics that makes them successful hunters is the good eyesight and large wingspans they possess.
Taking the vision of human beings for example, what looks sharp and clear to us at 5 feet is just as clear to a golden eagle from 20 feet away.
Also, their large wingspans helps then fly long distance in search of preys.
Therefore, the characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.

Which is true about the waste produced from mining? (1 point)
1. Toxic waste occasionally leaks to nearby ponds.
2. Toxic waste is typically dumped in nearby ponds.
3. Toxic waste is typically dumped in ponds, but only in ponds that cannot influence the environment.
4. Toxic waste used to be dumped into nearby ponds, but not anymore.
Toxic waste occasionally leaks to nearby ponds. That is option 1.
Wastes from miningMining is a process used by geologist to extract valuable minerals that are naturally deposited within the earth.
Example of such minerals are:
metals and coal, oil shale and gemstones, limestone and chalk, rock salt, potash, gravel, and clay.While mining processes are carried out, it leads to the generation of waste products such as:
ferrous and nonferrous metal ores, sulfur ores, apatite-nepheline concentrates, coal wastes and halite flotation wastes.These mining wastes can leak into the nearby ponds after a heavy down pour leading to the contamination of the ponds.

A large population of moths contains 35% white moths caused by the double recessive genotype, bb. What are all the allelic and genotypic frequencies for this population? (info on the equation also included)
Answer:
So after searching, I found the answer on a school tutor website :)
p = 0.41
q = 0.59
p^2 = 17%
q^2 = 35%
2pq = 48%
to check:
.41+.59=1 so thats correct
.17+.35+.48=1 this is correct too
i hope that helped :)
The answer is :
p = 0.41
q = zero.59
p^2 = 17%
q^2 = 35%
2pq = forty eight%
solution: 41+59=1
17+35+48=1
What are the frequencies of the alleles?Allele frequency refers to how not unusual an allele is in a populace. it is determined by counting how frequently the allele seems in the population then dividing by the whole quantity of copies of the gene. The gene pool of a population consists of all of the copies of all of the genes in that population.
What is the difference between allele and genotype frequency?Genotype frequency refers back to the variety of individuals with a given genotype divided with the aid of the whole quantity of people within the population while allele frequency refers back to the frequency of incidence or proportions of different alleles of a selected gene in a given population.
