The correct answer is D. Life cycles.

Explanation

The life cycle is a term used to refer to the set of processes or stages in the life of living organisms on Earth that preserve the balance of ecosystems. In this, four fundamental processes are to be born, to grow, to reproduce and to die, at the same time all of these stages allow the renewal of organisms such as plants or animals, this can be explained as stages such as reproduction lead to new organisms being born, similarly as organisms die these are replaced by organism that have just started the life cycle. So, the correct answer is D. Life cycles.

Xelga [282]

Answer: The statement is true

Explanation:

Persons with type O- blood are often referred to as the "universaldonors" based on the presence of neither type A or B antigen on the red blood cell, coupled with anti-A and anti-B antibodies. Hence, since

the type O blood lacks antigens, it does not clump when mixed with any of the other blood types in the recipient plasma

Thus, the type O blood is a universal donor

Describe the factors that influence the declining of Amphibians population

Alex73 [517]

Answer:

Hypothesized causes for the declines include habitat destruction (the most obvious cause), climate change, pathogens, introduced exotic species, pollution, and increased UV radiation. These agents may act alone or in combination to contribute to the decline of amphibian populations.

What did Hershey and Chase's research discover

Travka [436]

Through a series of experiments the duo conducted in 1952, Alfred Hershey and Martha Chase discovered that genetic material is found in DNA. Prior to their discovery, most scientists believed that genetic material was found in proteins due to their diversity and prevalence in cells.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or r

sdas [7]

Answer:

um...

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

What causes blood pH to drop in actively metabolizing/respiring tissues?

Novosadov [1.4K]

When a tissue's metabolic rate increases, so does its carbon dioxide waste production. When released into the bloodstream, carbon dioxide forms bicarbonate and protons through the following reaction: ... These waste products lower the pH of the blood, which increases oxygen delivery to the active muscles.
