Which statement provides evidence that mitochondria most likely evolved when a primitive eukaryotic cell engulfed a prokaryotic bacteria?

Answer:

Pour the water first, freeze it, and then pour the milk. The freezing point of raw unprocessed milk is ∼−0.5 degrees Celsius, so by keeping the barrel under 0 degrees, but above −0.5 degrees, you can keep the water frozen and the milk liquid, and be able to separate them.

You can freeze the whole thing below −0.5 degrees. Just don’t warm it suddenly above 0 degrees without separating the milk first.

In fact, the freezing point of milk can be and is used as a test to check whether water was added to milk by producers.

Explanation:

So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.

Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago

Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers

Answer:

Yes.

Explanation:

Yes, the adaption that allows some of these animals to run fast will be cause of natural selection because this fast running helps them to survive and save itself from predators. The organisms adapt certain features and characteristics in order to survive in that harsh environment that leads to natural selection. Natural selection occurs by selecting the best suited organism that can survive in that specific environment so this fast speed allows the organism to survive in their environment.

excerpt from History, by Ralph Waldo Emerson

There is one mind common to all individual men. Every man is an inlet to the same and to all of the same. He that is once

admitted to the right of reason is made a freeman of the whole estate. What Plato has thought, he may think, what a saint has

felt, he may feel: what at any time has befallen any man, he can understand. Who hath access to this universal mind is a party to

all that is or can be done for this is the only and sovereign agent.

Answer:

In all of these the carrying capacity would go down substantially

Explanation:

This is because these natural disasters are very detrimental to the environments and would decrease life.

In all the below conditions the carrying capacity would go down substantially.

An ecosystem have each and every organism and the relation between physical environment by which they interact. The function of ecosystem is to satisfy the need of humans by supplying them services and goods from nature.Ecosystem is the system in which both living as well as nonliving organisms are present in a particular location.

There are various types of ecosystem such as Grassland ecosystem, Tundra ecosystem, Desert ecosystem, Forest ecosystem. Biodiversity is all the different kinds of life living in a particular area like the variety of animals, plants, fungi and microorganisms like bacteria and virus that plays a major role in framing of natural world usually three levels of biodiversity are observed and these are genetic species, and ecosystem diversity.

Therefore, In all the below conditions the carrying capacity would go down substantially.

Answer:

The answer is A good luck!

Explanation:

Answer:

A. Bacteria

Explanation:

Displayed by how rapidly antibiotic resistance can develop, bacteria are the organisms that can make the quickest, significant adaptations.

Bacteria also reproduce by binary fission, where one bacteria becomes two.

This method of reproduction occurs rapidly, meaning that bacteria grow exponentially, as each bacteria will double. Over time, this will create a huge population.

This ability to reproduce quickly into a large population means that there is a greater chance for diverse mutations to appear. Some of these mutations will be helpful, and allow the bacteria to survive and reproduce when there are changes to their environments.

These mutations will lead to quick adaptations to the environment.

So, the correct answer is A. Bacteria

Bacteria can display the most significant adaptations to their environment in the shortest period of time.

Bacteria are the species that can make the quickest, most substantial modifications, as demonstrated by how quickly antibiotic resistance can emerge.

Bacteria can also divide in two through a process known as binary fission.

As a result of this quick process of reproduction, bacteria multiply exponentially since each bacterium doubles in size. This will eventually result in a vast population. With such rapid population growth, there is a higher likelihood that different mutations will manifest themselves.

Therefore,  Bacteria can display the most significant adaptations to their environment in the shortest period of time.

Explanation:

mitosis creates exact copies of the starting cell

In mitosis the two resulting cells are identical to the starting cell and identical to each other. Therefore, option (D) is correct.

In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Thus, equational division is another name for mitosis.

Making additional diploid cells is the goal of mitosis. Each chromosome is copied, and the copies are then distributed to the various sides of the cell. In this method, each new cell receives a copy of each chromosome when the cell splits in half.

blood comes into the right atruim from the body

Answer:

The circulation of blood is where basically the blood comes or goes into the right atrium from the body, this then moves into the right ventricle and is then pushed into what is called the pulmonary arteries in the lungs of a human. Once it has picked up oxygen, the blood will then travel back to the heart through the pulmonary veins, but this time it will go into the left atrium, so to the left ventricle and including out to the human body's tissues through the aorta.

Remove waste material, maintaining salt, pH and water balance in the body.

Explanation:

The main function of execratory system is to remove waste material, maintaining salt, pH and water balance in the body. Kidney filters the blood and removes waste material such as urea and nitrogenous waste etc, excess amount of salts and water from the body. It also maintains pH of the body by excretion of hydrogen ions as dihydrogen phosphate or ammonia from the blood and production or reabsorption of bicarbonate ions. So we can conclude that execratory system eliminates waste material, maintaining salt, pH and water balance in the body.

Answer:

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
