An ecosystem is an open system in terms of energy, and an open system in terms of matter

Answer:

c) Convection zone.

Explanation:

The electro-magnetic radiations form in the convection zone, which is the outermost layer of the solar interior. Temperatures in this region are cool enough that the atoms have enough energy to hold their electrons. This makes the convection zone darker or more opaque, trapping heat and causing the plasma appear to boil from convection.

Answer:

Radiative Zone

Explanation:

When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.

When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

The progeny includes recombinant phenotypes indicating that the genes are linked. Specifically, the occurrence of the phenotypes "ebony, scarlet," "ebony, spineless," and "scarlet, spineless" indicates that the genes e, st, and ss are on the same chromosome.

These are the recombinant phenotypes: ebony, scarlet (136), ebony, spineless (694), and scarlet, spineless (20).

From the given data, we can observe that the progeny with the recombinant phenotypes account for a total of 136 + 694 + 20 = 850 individuals.

For the map distance between e and st, we need to determine the total number of progeny and the number of recombinant progeny (ebony, scarlet).

Total progeny = 134 + 16 + 136 + 694 + 156 + 736 + 20 + 108 = 2000

Number of recombinant progeny (ebony, scarlet) = 136

Map distance between e and st = (Number of recombinant progeny / Total progeny) * 100

                              = (136 / 2000) * 100

Map distance between e and st = 6.8 units

Cloning an extinct species is a possible answer for a suffering ecosystem. The only drawback is that scientists have not yet mastered cloning. When attempting to clone animals often they are deformed and therefore not able to reproduce let alone survive. Even when scientists do manage to clone animals without killing them, it takes many generations of selective breeding to get the species you are trying to revive which takes time, making the ecosystem even more damaged.

The study of a living being is called biology.

The correct answer is not reliable.

The duplication of the genes in the laboratory is called cloning.

The first clone species was the sheep whose name was a dolly.

Those species which are on the verge of extinction is called endangered species and they need extra protection to carry their gene to the next generation.

The cloning will be able to multiply the gene in the in-vitro culture but they will have a direct impact on the natural genes and the combination of the gene present in nature.

The natural species have all the desired genes which help them to survive in nature, whereas the clone species will not have the desired gene which is required to adapt to nature and they will extinct eventually. If these genes pass on to the next generation then the endangered species will also have less chance to survive in nature.

Hence, in my opinion, they cloning is not a suitable way to save endangered species.

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.

The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.

Hope you could get an idea from here.

Doubt clarification - use comment section.

Carbon cycle is a biogeochemical cycle in which the carbon atom continously moves in the atmosphere through different forms and processes.

The carbon cycle is the biogeochemical cycle which describes the process through which carbon atoms continually travel from the atmosphere to back to the Earth and then back into the atmosphere. This cycle goes on repeatedly. Since our planet and its atmosphere forms a closed environment, the amount of carbon in this system does not change, it only transforms from one form to another.

The processes which takes place in carbon cycle include photosynthesis, decomposition, respiration, and combustion. Carbon cycles from the atmosphere into the plants and living things. For example, carbon is a pollutant in the atmosphere which is present as carbon dioxide gas.

Carbon moves from the plants and animals to soil. When the plants and animals die, their bodies, wood, and leaves decays which being carbon into the ground. Some of this carbon is buried and become fossil fuels in millions of years. Carbon moves from living things to the atmosphere through respiration in which they inhale oxygen gas and exhale carbon dioxide gas.

Answer: CFU/mL = 14200 CFU/mL

Explanation:

Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.

To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.

So, the equation is:

CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)

100 microliters = 0.1 mililiter

1/10 = 0.1 (dilution factor)

Replacing the information from the question:

CFU/mL = 142 / (0.1 mL x 0.1)

CFU/mL = 14200 CFU/mL

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Answer:

same

Explanation:

Asexual reproduction gives rise to two physically and genetically identical daughter cells. Thus, the genetic information remains the same.

In asexual reproduction, the daughter cells divide through the process of mitosis, which results in two daughter cells from one parent cell.

In mitosis, the chromosomes which are duplicated segregate into the two emerging cells around which then a nuclear membrane forms. In this case, there is no recombination by crossing-over or chiasmata formation that happens in the case of meiosis.

It is the recombination by crossing-over or chiasmata formation that results in varying genetic information.
