A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. The complete cell cycle requires 24 hours. Match the average duration to the appropriate cell cycle stage in these cells. M phase prophase metaphase telophase 4.8 hours 14.4 minutes 2.4 hours 36 minutes

Answers

Answer 1

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

Which element has the least neutrons in the nucleus?
Aluminum
Nitrogen
Helium
Fluorine

Answers

Answer:heh

Explanation:

Aluminium , mass no = no of proton + neutron = 27

atomic no = no of proton = 13

no of neutron = 27 - 13 = 14

Nitrogen  , mass no = no of proton + neutron = 14

atomic no = no of proton = 7

no of neutron = 14 - 7 = 7

Helium   , mass no = no of proton + neutron = 4

atomic no = no of proton = 2

no of neutron = 4 - 2= 2

fluorine    , mass no = no of proton + neutron = 19

atomic no = no of proton = 9

no of neutron = 19-9 = 10

To help meet the world's demand for food, which biotechnological
process is most likely to be used by agricultural industries?
O use of transgenic crops
O crop diversification
O spraying of organic herbicide
crop rotation

Answers

Answer:

use of transgenic crops

Explanation:

Since transgenic crops are genetically modified, the pros are that: there is more crop yield, increased nutrients, etc.

The use of transgenic crops is most likely to be used by agricultural industries. Hence, option  A is correct.

What are transgenic crops?

Crops that have undergone genetic engineering techniques to alter their DNA are referred to as genetically modified crops. Plant genomes can be modified physically or by transferring sequences contained in T-DNA binary vectors using Agrobacterium.

The goal of introducing a gene combination into a plant is to increase its productivity and usefulness. This technique offers benefits like extended shelf life, increased yield, improved quality, pest resistance, heat, cold, and drought tolerance, as well as resistance to a range of biotic and abiotic challenges.

The use of transgenic crops is most likely to be used by agricultural industries. Hence, option  A is correct.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis

Answers

Answer:

The color of light determines how effective chlorophyll pigment will be at absorbing light.

Explanation:

Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.

Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

in what ways can overpopulation be beneficial to differential reproductive success?

Answers

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

A study is being done to test the effects of temperature on the number of microbial colonies. Four different incubators are set up, each at a different temperature with one culture plate in each. Each plate has the same nutrient content, pH, and are inoculated with microorganism samples from the same source. At the end of the experiment, the number of colonies on each plate is counted. What is the independent variable

Answers

Answer:

The correct answer is - the different temperatures of incubators.

Explanation:

An independent variable is a variable in a study or research which is manipulated or changed to check or find the effect on the dependent variable. The independent variable is the only factor that changes in research while other factors remain constant that can affect the result in the study.

In this case or study, there is the only factor that is manipulated is the temperature of incubators is manipulated to see the effect of temperature on the number of microbial colonies. Thus, the different temperatures of incubators is the independent variable here.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.

Answers

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?

Answers

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2

                                                 (Reactants)            (Products)
