Answer:

The main difference is in its structure and form of nutrient and water collection.

Explanation:

Vascular plants are those that contains roots, stem and leaves, in these the roots are responsible for absorbing nutrients from the ground and serves as a food reserves for the entire plant.

Non-vascular plants lack internal tubes that carry water and nutrients throughout the plant, for this reason this kind of plant are usually found in humid or sumerged places, since in this type of environment they can absorb water and nutrients to through its tissues.

vascular transports water, distributtes food, and found in the roots, stems, and leaves. vascular plants grow faster and taller.

nonvascular plants do not grow taller like the mosses.

A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals.
FF genotype frequency:
98÷200=0,49. There are approximately 5 homozygous dominant mice in 10.
Ff genotype frequency:
84÷200=0,42. There are approximately 4 heterozygous mice in 10.
ff genotype frequency:
18÷200=0,09. There are approximately 1 homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
 $\frac{(98*2)+84}{400}$ =0.7
There are 7 F alleles in 10 random alleles.
f allele frequency:
$\frac{84+(18*2)}{400}$ =0.3
There are 3 f alleles in 10 random alleles.

Glycolysis

dolphi86 [110]

Answer:

E) can usually make enough ATP for skeletal muscle function

Explanation:

Glycolysis is the main process by which cells obtain energy. During glycolysis, glucose is fully oxidized to obtain ATP, this is the 'fuel' for cellular function. Glycolysis is oxygen dependant, meaning that in order to successfully complete the process, enough oxygen must be available.

There are a few exceptions in which glycolysis is unable to provide enough ATP, an example is strenuous exercise. In this case the speed of oxygen consumption is very high, therefore at some point the oxygen intake is not enough. There are several mechanisms that regulate the production of ATP. In case of strenuous exercise, different process are activated to supply the cell with the necessary energy to keep on functioning.

Among the latter mentioned processes, there is anaerobic production of the oxidation of lactate, that does not require oxygen. Other example is the usage of creatine phosphate to obtain energy. Therefore, muscular cells have many ways of obtaining energy, but this secondary mechanisms are only activated in specific situations.

Why is it important that human chromosomes have many origins of replication

8_murik_8 [283]

Answer:

Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.

Explanation:

Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
