Answer:
Removing the legumes also removes the bacteria, which contain ammonia. This removes nitrogen from the soil. The nitrogen is relocated to the bodies of the organisms that consume the legumes. The nitrogen in organisms will be returned to the environment in waste products and when the organism dies and decomposes. All of these processes are part of the nitrogen cycle.
Plants containing only chlorophyll b are exposed to radiation with the following wavelengths: 10nm (X-rays), 450nm (blue light), 670nm (red light), and 800nm (infrared light). Which plants harness the most energy for photosynthesis?
The plant with blue light is absorbed by chlorophyll B and the plant gets a lot of photons for its photosynthesis. Because the blue lights, comes first in this peak of absorption.
Chlorophyll, is the primary pigment used in the process of photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
In plants the color of the pigment comes from the wavelengths of light that are reflected, or the one those are not absorbed. For Chlorophyll, the green pigment is most common as it absorbs all wavelengths of visible light except green, which it reflects.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

What's the difference between primary succession and secondary succession?
Primary succession and secondary succession are two different processes of ecological succession that occur after a disturbance in an ecosystem.
Primary succession is the process by which a new ecosystem is formed on barren land where no soil or organisms exist, such as after a volcanic eruption or glacial retreat.
The process begins with the colonization of bare rock or sand by pioneer species like lichens and mosses. Over time, these organisms break down the rock or sand, creating soil that can support the growth of larger plants like grasses and shrubs. Eventually, trees and other complex organisms take root, creating a mature ecosystem.
Secondary succession, on the other hand, occurs when a disturbance, such as a wildfire or human activity, destroys an existing ecosystem but leaves behind soil and some organisms.
The process begins with the growth of pioneer species that can quickly colonize the area, such as weeds and grasses. As the ecosystem recovers, more complex organisms move in, and the ecosystem slowly returns to its previous state.
In summary, primary succession occurs on bare land without soil or organisms, while secondary succession occurs on land that has been disturbed but still contains some soil and organisms. The processes of succession are essential for the renewal and recovery of ecosystems after a disturbance.

Which of the following best describes high G+C bacteria
a.) Gram-negative bacteria that include spirochetes, planctomycetes, and the CFB group
b.) A gram-positive group that includes Bacilli
c.) Gram-negative bacteria that include a large group composed of five classes of bacteria
d.) A gram-positive group that includes the Actinobacteria
Answer:
d.) A gram-positive group that includes the Actinobacteria
Explanation:
The best description of high G+C bacteria is option d) A gram-positive group that includes the Actinobacteria.
High G+C bacteria, also known as high guanine-cytosine bacteria, refer to a group of bacteria characterized by a high proportion of guanine (G) and cytosine (C) nucleotide bases in their DNA. This characteristic can be determined by analyzing the DNA composition of bacteria.
Option d) states that high G+C bacteria belong to a gram-positive group that includes the Actinobacteria. This is the most accurate description of high G+C bacteria. Actinobacteria are a phylum of gram-positive bacteria, known for their high G+C content. They are characterized by their filamentous growth and the formation of branching networks of hyphae, similar to fungi. Actinobacteria include a diverse range of organisms, such as the genus Streptomyces, which produce many antibiotics, and Mycobacterium, which includes the species responsible for tuberculosis and leprosy.
Options a), b), and c) are not accurate descriptions of high G+C bacteria. Option a) mentions gram-negative bacteria and includes spirochetes, planctomycetes, and the CFB (Cytophaga-Flavobacterium-Bacteroides) group, which are not specifically associated with high G+C content. Option b) refers to a gram-positive group that includes the Bacilli, which generally do not have a high G+C content. Option c) mentions gram-negative bacteria composed of five classes, but it does not specifically address high G+C content.
Therefore, option d) is the most accurate description of high G+C bacteria, as it correctly identifies them as a gram-positive group that includes the Actinobacteria.

E. In 7 years, 1000 children suffered from anemia.
A study showed that morbidity of children with anemia was 7:1000. This means that (B) 7 children out of 1000 had anemia or suffered from anemia.
The study showed that morbidity of children with anemia was 7:1000. The term "morbidity" refers to the incidence of a disease or the prevalence of a condition. The ratio 7:1000 indicates that for every 1000 children, 7 of them had anemia or suffered from anemia. This means that 0.7% of the children in the study had anemia.
However, it does not mean that 7 children out of 1000 died of anemia or that they recovered from blood-borne pathogens. It simply means that 7 out of 1000 children had anemia. Morbidity is often used in public health to determine the incidence of a disease and to track its prevalence over time. It is a useful indicator of the health of a population, as it can help public health officials to identify trends and develop strategies to prevent and treat diseases.
In conclusion, the study showed that 7 children out of 1000 had anemia or suffered from anemia. The correct answer is B.

how are the inheritance of yellow pod color in peas and cytic fibrosis in humans similar to each oter
Recessive traits are coded by two copies of recessive alleles. The inheritance pattern is autosomal recessive. Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.
What are recessive traits?Recessive traits are those coded by recessive alleles and can only be expressed in individuals whose genotyope is homozygous recessive. This is, individuals who only carry recessive alleles for that trait.
Alleles (dominant and recessive) are variants of the same gene.
The gene codes for a characteristic, and the allele codes for one variant of the characteristic, which is the trait.
So recessive traits are coded by the recessive variant of a gene.
Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
For instance,
The characteristis pod color is coded by a diallelic gene. The dominant allele codes for green and the recessive allele codes for yellow. Yellow is the recessive trait.The characteristic cystic fibrosis is coded by a diallelic gene. The dominant allele codes for normal individuals, while the recessive allele codes for affected individuals. Cystic fibrosis is the recessive trait.Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.
