How is the epithelium suited for the substances ?
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answer.
Answer:
[tex]BMR_{women} = 1401.75[/tex]
Explanation:
According to Harris-Benedict equation the Basal metabolic rate of an organism can be calculated by using the following formula for both men and women -
[tex]BMR_{men} = 10 * W + 6.25 * H - ( 5 * A) + 5[/tex]
[tex]BMR_{women} = 10 * W + 6.25 * H - ( 5 * A) - 161[/tex]
Here, W is the weight in Kgs
H is the height in Cms
and A is the age in years
My weight is equal to [tex]65[/tex] Kgs
My height is equal to [tex]167.64[/tex] cms or [tex]5.5[/tex] feet
Gender - female and
Age is [tex]27[/tex] years
Substituting the given values in above equation, we get
[tex]BMR_{women} = 10 * 65 + 6.25 * 167.64 - ( 5 * 27) - 161\\[/tex]
[tex]BMR_{women} = 1401.75[/tex]
Sample Answer:
Brian is a 15-year-old boy who weighs 130 pounds and is 68 inches tall. He engages in moderate exercise.
Convert weight and height to the metric system.
Weight: 130 lbs. = 130 × 0.45 = 58.5 kg
Height: 68 in. = 68 × 2.54 = 172.72 cm
Calculate BMR.
For men, BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5 BMR = (10 × 58.5) + (6.25 × 172.72) − (5 × 15) + 5 = 1594.5 calories
Calculate daily calorie needs.
For moderate exercise, daily calories needed = BMR × 1.55 = 1594.5 × 1.55 = 2,471.475 calories

WORD BANK: body cell gamete-producing cell diploid cell one cell division two cell divisions four haploid cells two diploid cells the same half chromosomes parent cell
Answer:
id understand it
Explanation:
Mitosis is the process of cell division that occurs in the body cells which produces two diploid cells that contain the same number of chromosomes as compared to the parental cell.
What is Cell division?Cell division may be defined as a type of biological process through which a parent cell divides into two daughter cells or more that are either genetically identical or genetically unique to the parental cells. There are two types of cell divisions that exist, i.e. mitosis and meiosis.
While meiosis is the process of cell division that occurs in the gamete-producing cells which produce four haploid cells that contain half the number of chromosomes as compared to the parental cell.
Therefore, both types of cell division are well described above in the same frame.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
Answer:
E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.
Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.
Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.
When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.
Hence, the culture of bacteria carrying plasmid will be able to survive only.
Maximum transformation to tetracycline achieved when cells were harvested from L broth at 5.0-6.0 cfu/ml , followed by washing twice in cold.
The susceptibility of E.coli strain to culturing transformation by plasmid DNA was examined and optimized.
TransformationCells grown within the presence of D - cycloserine ( Cyc ) rather than Neg Gram (N x) transformed better. The presence of 5 mm Mg2+ ions in washing and CaCl2 solutions stimulated transformation about 2-fold.
Optimal conditions for transformation included a pH range of seven. 25-7.75 and a cell-to-DNA ratio of about 1.6 . 10(8) cfu/ng plasmid DNA.
The frequency of transformation was highest when cells were exposed to 100 mM CaCl2 in 250 mm.
Composition[tex]\rm KCl + 5 mM \;MgCl2 + 5 mM \;Tris[/tex]
pH 7.6, before mixing with DNA
Therefore, the results of culturing transformed E.coli within the presence of tetracycline is justified.

Which is the result of genetic drift?
A) increase in the size of the gene pool
B) a decrease in genetic diversity
C) an increase in total allelic frequency
D) decrease in the size of the population
Answer:
B.)
Explanation:
Although genetic drifts can change allelic frequencies, it doesn't specifically increase it. It does not increase in the size of the gene pool nor does it cause a decrease in the size of the population. B is correct.
The result of genetic drift is a decrease in genetic diversity.
What is genetic diversity and its example?Genetic diversity is defined as genetic variability present within species. E.g. Different breeds of dogs, different varieties of rose flower, wheat, rice, mangoes, etc.

How does a DNA sequence determine a trait
Answer:The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. This is the direct connection between your genes and your traits. ... Then cellular structures, the ribosomes, translate the RNA into proteins.
Explanation:
The instructions for making all the proteins are carried by the DNA, these proteins determine one's traits.
What is the importance of DNA sequence?The genetic code determines the proteins manufactured by the cell. The proteins refers to the strands of amino acids. The DNA sequence of the genes determines the order of amino acids in a protein. This is the direct association between the traits and the genes.
It is the DNA, which carries all the instructions for the manufacturing of the proteins, these proteins determine the traits. DNA does not possess the tendency to leave the nucleus, thus mRNA copies the message of DNA and carries it to a ribosome. The mRNA is read by the tRNA that brings in the appropriate amino acid to produce the protein. This protein determine a trait.
Thus, DNA sequence determine a trait, as they provide instructions for the manufacturing of the proteins, these proteins further determine a trait.
