What is Meiosis?

Meiosis refer to the special type of the cell division with respect to the germ cells with respect to the organism that should be se-xually reproduction.

Also, it generated the gametes, like the sperm or egg cells. Also, it includes the 2 rounds of division that leads in four cells with only one copy for every chromosome.

Why are seals able to live the coast of Antarctica while frogs snakes, and panthers not?


A. Seals can swim

B.seals are predators

C.seals have fur and blubber

D.seals are warm-blooded animals

Answers

Tbh it’s either c or d because c and d are both correct
The answer is C. My answer is because A and B are irrelevant to the question, so for that it can be eliminated. But between C and D, C makes much sense. Although D, says that seals are warm blooded and is true, however frogs (amphibians) and snakes (reptiles) they are cold blooded. They need sun in order to feel warm or the heat to adjust or accommodate their bodies temperatures, unlike panthers and seals they’re warm blooded they naturally have fur and are able to regulate their bodies temperature. Therefore D is eliminated. The correct answer is C, because seals have fur and blubber it’s much more durable, and are almost as if impenetrable for the freezing water and colder weather to pass through their fur. That is why they are able to live the coast of Antarctica.

The correct answer is C.

During the bacterial transformation lab, what was the primary purpose of including Ampicillin in the agar

Answers

Answer:

allows for selection of E. coli mutants that successfully picked up the plasmid

Explanation:

Ampicillin is a penicilin type medicine or antibiotic that can treat the infections caused by bacteria.

In bacterial transformation lab, the ampicillin is added in the agar in order to select the E.coli mutants which picked the plasmid and have gained ampicillin resistance gene. Bu doing so, it causes the production of the enzymes that prevents the activity of the ampicillin as well as the bacteria survive. The ampicillin antibiotics present in the agar kills the bacteria without having the ampicillin resistance gene.

Explanation:

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.

Answers

Answer:

The flow of energy in ecosystems is unidirectional or one-way.

Explanation:

Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.

Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to  organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.

Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.

Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.

B
These organelles are both important in the regulated transport of molecules within cells.
с
These organelles are both important for the conversion of energy to a usable form for cells.
D These organelles are both important for the use of cellular genetic information to make proteins.

Answers

Answer:

The correct answer is - с. These organelles are both important for the conversion of energy to a usable form for cells.

Explanation:

Chloroplast and mitochondria are the two organelles that are essential for the biosphere specially autotrophs like plants and heterotrophs as chloroplast is the organelle that converts light energy into chemical energy by forming sugars by the process called photosynthesis by trapping the sunlight.

This chemical energy that is stored in glucose molecule moves to the mitochondria where by the procee of the cellular respiration the chemical energy converted to the ATP, the energy form that is used by the cell for the performing its function.

Under what conditions is it ethical for conservationists who live in the United States to lobby government officials in Brazil, Indonesia, and other tropical countries to slow the rate of loss of old-growth forest

Answers

The correct answer to this open question is the following.

I can say that under the following conditions it is ethical for conservationists who live in the United States to lobby government officials in Brazil, Indonesia, and other tropical countries to slow the rate of loss of old-growth forests.

First, American conservationists have to use diplomatic approaches to use the correct language to ag¿ddress the issue and the political leaders of those countries.

Then, they have to fully understand what the situation is, knowing all sides of the story so they can avoid any mistakes.  They have to include the official version of the governments to try to not bias their opinions.

Once they have done that, then they will have all the elements to make an official statement about the critical situation in those above-mentioned places.

And one very important thing, they have to be careful in using polite words such as "invite" or "exhort" when addressing the federal institutions of those countries.
