The cell spends most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.

What is the time spent in the cell cycle?

The cell enters the cell cycle, and the first stage is the G1 phase, where the cell grows and spends a lot of time nearly 11 hours and then the cell enters the S phase. In the S phase, the DNA replicates and spends nearly 7 hours, and then in the G2 phase, 3 to 4 hours are spent by the cell, with the remaining 1 to 2 hours spent in the M phase, also called the mitosis or division phase.

Hence, cells spend most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.

Crime-scene work often involves obtaining a DNA sample from a drop of blood to help identify persons who may have been involved. Frequently, the size of the DNA sample is extremely small, too small for easy analysis. Which of the following laboratory procedures could criminologists use to amplify the amount of DNA present?

A: Cloning and gel electrophoresis
B: Cloning and polymerase chain reaction (PCR)
C: DNA splicing and polymerase chain reaction (PCR)
D: Vector amplification and DNA splicing

Answers

Amplification of DNA is a very useful tool in the study of the human genome. DNA amplification ensures the production of multiple copies of the needed segment.

Criminologists can use Cloning and PCR to amplify the amount of DNA present...

Cloning involves creating identical copies of a particular DNA segment in study. Then amplification of the DNA using polymerase chain reaction will aid in amplifying and producing thousands of these copies of short targeted segments in minutes. This tool is very useful in ensuring the multiplication of that particular targeted sequence for analysis.

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans

Answers

From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.

---------------------------------------

Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.  

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule".

This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels (4 or 5).  

If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.

5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.

 

1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.

164.5 MJ of this energy is tranferred to the following trophic level.

Trophic Levels in Food Chain

Each of them represents a trophic level of energy flow transmitted through food. The first trophic level is formed by the producers and the last one is the decomposers.

Primary Consumers

Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.

Explanation:

Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.

are environmental factors more likely to affect genotype or phenotype?

Answers

Environmental factors are more likely to affect phenotype than genotype.

Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.

The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.

Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.

Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.
