Answer;

-A surface area/volume ratio of 6:1 means the cell's ability to get materials it needs that move across its surface is very efficient.

-Increased surface area to volume ratio makes diffusion and osmosis much more effective. Cellular concentrations of ions, nutrients, salts, etc can occur much more quickly and efficiently.

Explanation;

-The surface area to volume ratio of a cell is the relationship between two measurements.That is; the ratio of Surface area to volume. It shows the comparison between the size of the outside of a cell and the amount inside. Small or thin cells have a large surface area compared to the volume.

It depends on the unit of the ratio 6:1. If it is in <span>c<span>m<span>−1</span></span></span><span>, then it means that it is similar to a cell of size 1 cm^3,
 which is normally too big to get materials from the surface
hope it helps</span>

What are the Amino acids of the mutated DNA sequence: TAC ATC TTG GCG ACG ACT
Natali5045456 [20]

Answer:

Tyr Ile Leu Ala Thr Thr

Explanation:

In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of  20 amino acids and these amino acids are coded by a pair of three bases.  

There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).

The given mutated DNA sequence will also code for some amino acid, that is as follows:

TAC - Tyr (Tyrosine)

ATC - Ile (Isoleucine)

TTG -  Leu (Leucine)

GCG - Ala (Alanine)

ACG - Thr (Threonine)

ACT - Thr (Threonine)

Thus, The mutated DNA sequence  TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.

What would happen to a cell if, during the splitting of chromosomes, two did not separate- and one cell got a double set and the
cestrela7 [59]

Answer:

Explanation:

The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others. The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.

Rachael wants to test how sunlight impacts plant growth over time. She will add varying amounts of light to different sets of pl
Mrrafil [7]

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
