Answer:
Basal Layer
Explanation:
The epidermis contains a variety of cells. Most of the cells are keratinocytes, which are formed by division of stem cells in the basal layer.
Answer:
Number of cells killed at the end of the experiment
Explanation:
<em>In research, the dependent variable is one whose value is dependent on another variable - a variable that is supplied by the researcher during the course of the experiment which is also known as the independent variable</em>.
In this case, since the main objective of the research was to determine the most effective antibiotic against the E. coli, the variable that is supplied by the researcher (the independent variable) is, therefore, the different antibiotics while the variable whose value varies based on which of the antibiotics is introduced is the number of dead bacterial cells.
Therefore, the dependent variable is the<u> number of cells killed by each antibiotic.</u>
Answer:
When we look at a population, we see that an individual trait may have multiple phenotypes due to <u>genetic</u> variation in the type of protein produced.
Explanation:
The phenotype constitutes the observable traits of an individual, such as height, eye color, and blood group. The genetic contribution to the phenotype is called genotype. Some traits are largely determined by genotype, while other traits are largely determined by environmental factors. Genetic variation is the raw material from which the diverse populations of a species adapt to changes in their environment. New genetic variations arise within populations from spontaneous mutations of a gene or by immigration of individuals from genetically distinct populations. Each chromosome contains many genes, the basic functional and physical units of genetic inheritance. Genes are specific sequences of the bases that encode instructions to form proteins. The DNA sequence is the specific longitudinal arrangement of the bases in the DNA chain. Each gene has a specific DNA sequence. From a common heritage that is the gene endowment of each cell, identical in all of them, the endowment has diverse mechanisms that make it possible to express it differently in each cell and in each individual. That is, although the genetic code and the systems for decoding are basically universal, there are complex differential regulation phenomena that constitute the basis by which each individual responds differently to the environment, and by which each living cell is identified, that is , that the action of a gene, then, is subject to multiple influences external to it, capable of modifying its expressive capacity from the first step, the transcription, to the last, the post-translational transformation of the protein.
Answer:
The answer is given below.
Explanation:
Such a mutation would have an effect upon that Four design. It has been said, such substitution is a component of the linking of the alpha 1 as well as beta 1 groups, and those of the unit linking of each si 4 design, quite assured.
The design will be affected to a large extent since Y seems to be a polar amino acid, and it should not be substituted by an enlarged hydrophobic side chain.e Those units mentioned in such statement would not be able to bind or bind to one another properly, due to which lack in protein.
The correct option is B.
The process of meiosis give rise to four daughter cells that are haploid, that is, they contain half the number of chromosomes of the diploid parent cells. In the process of mitosis, two daughter cells are usually produced.<span />
