When growing, as a cell gets bigger, what happens to its surface area to volume ratio?
marysya [2.9K]

<u>Answer</u>:

Surface area to volume ratio decreases.

<u>Explanation</u>:

When the cell enlarges beyond its capacity, it fails to supply enough material that can cross the membrane sooner so as to occupy the cellular volume. Hence the diffusion rate also decreases so as the ratio. The cell carry out its various functions to sustain through diffusion when diffusion rate is low it will ultimately affect the ratio. Bigger size affects the diffusion of the material to the out of the cell. as we know the diffusion occurs across the surface of the cell.

Answer: Las plantas también proporcionan agua a través de los estomas y los animales proporcionan o liberan agua a través de la respiración, la transpiración y la micción.

Explanation: Las plantas también proporcionan agua a través de los estomas y los animales proporcionan o liberan agua a través de la respiración, la transpiración y la micción. Las plantas tienen una pequeña abertura llamada estoma por la cual la planta toma aire dentro de su cuerpo y libera agua para regular su temperatura mientras que por otro lado, los animales liberan agua de su cuerpo a través de la respiración en forma de vapores y de la micción en forma de líquido.

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp
lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)-  123

Total number of offsprings= 77+  65+ 123

                                            = 265

Now to calculate allele frequency of A1=

\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})

= 77/265 + 1/2( 65//265)

=  0.290+ 0.122

= 0.413

Thus, 0.41 is correct.

The mitochondrial matrix has what charge compared with the intermembrane space?
Solnce55 [7]
The matrix (inside mito) has a negative charge compared to the intermembrane space (outside of mito but still inside) because positively charged protons are constantly pumped from the matrix to the intermembrane space. A cell oxidizes an organic molecule producing 3 NADH molecules and 3 FADH2 molecules..
