Which of these terms refers to materials leaving the cell? A endocytosis B exocytosis

Answers

B - exocytosis.

Think of like materials EXitig the cell via EXocytosis

Final answer:

Exocytosis is the process that refers to materials leaving the cell. It involves the enveloping of waste material in a membrane which fuses with the plasma membrane's interior, allowing for expulsion of waste into the extracellular space.

Explanation:

The term that refers to materials leaving the cell is B. Exocytosis. Exocytosis is essentially the process of moving materials from within the cell to the extracellular fluid. This is achieved through the enveloping of waste material in a membrane which then fuses with the plasma membrane's interior. This fusion causes the membranous envelope to open, allowing the expulsion of waste materials into the extracellular space. Examples of this process include cells like those of the stomach or pancreas, which manufacture and secrete enzymes via exocytosis, or endocrine cells releasing hormones throughout the body.

The food for dicot embryos is stored in the while food for monocot embryos is stored in the .

Answers

A monocot or monocotyledon (mono- means one)has only one seed leaf while the dicot or dicotyledon (di- means two) has twoseed leafs. Note that a cotyledon is a seed leaf. The seed inside the monocotand dicot needs a source of energy to support the embryo until it can collectits own food. In monocots, endosperm is the source of food located inside theseed coat but is separated from the seed leaf. In dicots, the seed leaf containsthe endosperm. 

The food for dicot embryos is stored in the endosperm while food for monocot embryos is stored in the cotyledons.

there are distinct differences and similarities between prokaryotes and eukaryotes; the similarities are

Answers

The similarities are...
- they both have DNA chromosomes (although prokaryotes have DNA chromosomes in the form of a single stranded loop and eukaryotes have DNA chromosomes that are linear and thread like)
- they both have ribosomes (although ribosomes in prokaryotes are scattered in the cytoplasm and ribosomes in eukaryotes are either attached to the rough ER or free in the cytoplasm)
- they both have cell membranes 
- some prokaryotes (bacteria) and some eukaryotes (fungi, plants and some protists) have cell walls

What happens during anaerobic cellular respiration?

Answers

During aerobic respiration, the cells still need to release energy without oxygen. therefore, they directly split glucose to form lactic acid. this releases a lot less energy than aerobic respiration and the lactic acid accumulates in your muscles, causing aching. 

Answer:

In anaerobic respiration, one molecule of glucose is broken down into two molecules of ethanol (in yeast) or lactic acid (in muscle cells) with a net gain of two molecules of ATP (adenosine triphosphate).

Two molecules of carbon dioxide are released as the byproduct.

It helps in regenerating the NAD⁺ lost in the process of glycolysis.

The overall process is termed as fermentation.

Lactic acid fermentation is catalyzed by the enzyme lactate dehydrogenase and alcohol (ethanol) fermentation is a two-step process which is catalyzed by pyruvate decarboxylase and alcohol dehydrogenase.

Answers

neurons because they make up most of the system. and they transmit the impulses and connect different parts of the system.
Neurons because the actually control many of the different receptor cells that make up the cns, like motor neurones and sensory neurones

Which is a biotic factor

Answers

Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.

Explanation:

Hello! Let's solve this!

An ecosystem is made up of parts with life and parts without life. Within the lifeless parts, there are rocks for example. These lifeless factors are called abiotic factors.

The factors that are alive are called biotic factors.

For example, we find plants and animals.
