Multiple soil horizons make up a soil profile. Soil horizons are distinguishable regions of soil. They run parallel to the surface and have different characteristics. The soil horizons include the A horizon, E horizon, B horizon and C horizons.
The soil profile is a vertical cross section showing these horizons.
Answer:
<em>Look below.</em>
Explanation:
This question may have made it seem like natural selection is a harmful process -- be wary of this. To understand this, you have to note something known as heterozygote advantage. All this means is that the heterozygotes, the organism that expresses both the dominant and recessive alleles, rather than the homozygotes, organisms that express both dominant or both recessive alleles, have an advantage. An example is with sickle cell disease. People heterozygous for the sickle cell trait are more resistant to malaria for some reason, whereas the homozygotes are not. Because heterozygotes (which have a harmful allele and normal allele) have the advantage, natural selection selects for this trait and favors it. This leads to the "persistence of harmful or even lethal allele[s]." Again, just because the organism has a lethal allele isn't necessary always a bad thing. :)
Answer:
See the answer below
Explanation:
The amount of light available to Chlorella culture might affect the growth dynamics of the alga <u>because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.</u>
The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:
<em>The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.</em>
Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.
Eukaryotic.
In prokaryotic cells, the dna is inside the cytoplasm
Answer: buccinator
Explanation:
The buccinator is a muscle that looks quadrilateral in shape. It is present between the internal of mandible and maxilla. It basically forms the anterior portion of the cheek and also forms the part of the oral cavity. The buccinator muscles compresses the cheeks against the teeth. These muscles are used to perform the acts like blowing. The buccinator muscles are the assistant muscles which helps in the process of mastication or chewing and in case of neonates it is used to suckle.
