Complete question:

Although most solutes that enter or exit the cell are relatively small (inorganic ions, sugars, or amino acids), occasionally the movement of larger molecules into or out of the cell is required. For example, certain cells secrete proteins, such as pancreatic cells that secrete insulin. Other cells take up food particles or even entire cells, such as lymphocytes in your immune system. Transport of such large materials into and out of the cytosol cannot be accomplished by transport proteins in the plasma membrane. The transport of large molecules is accomplished by bulk transport via exocytosis and endocytosis. Like other forms of active transport, bulk transport requires an input of energy. Before beginning this tutorial, watch the segment of the Membrane Transport animation on exocytosis and endocytosis. Observe the role that vesicles play in the transport of materials into and out of the cell.

Part A

Sort the phrases into the appropriate bins depending on whether they describe exocytosis, endocytosis, or both.

a. decreases the surface area of the plasma membrane

b. requires fusion of vesicles with the plasma membrane

c. forms vesicles from inward folding of the plasma membrane

d. transported substances never physically cross the plasma membrane

e. increases the surface area of the plasma membrane

f. requires cellular energy

g. secretes large molecules out of the cell

Answer:

a. -->  ENDOCYTOSIS

b. -->EXOCYTOSIS

c.--> ENDOCYTOSIS.

d. --> BOTH

e. --> EXOCYTOSIS

f. --> BOTH

g. --> EXOCYTOSIS

Explanation:

To answer the question, first, we need to know the meaning of endocytosis and exocytosis.

Endocytosis and exocytosis process refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

Cells can export many substances in vesicles or vacuoles that originate in specific organelles like, for instance, the Golgi complex. Organelles form new vesicles or vacuoles with substances destined for exportation and send them forward to the membrane. When they get there, they fuse to the cell membrane, releasing all their content to the extracellular space. When fussing, the vesicle membrane increases the size of the cellular membrane. This process is exocytosis, and its direction is always from the inside of the cell to the outside. But there is also another vesicle-mediated transport that occurs from the exterior to the cell interior, the endocytosis process. It happens when the cell imports material from the extracellular space through the invagination of the membrane, producing a new vesicle that surrounds the incoming material. The invagination ends in strangulation of the membrane, releasing the new vesicle in the cytoplasm. This process decreases the size of the cellular membrane because it uses part of it to engulf the material.

Now that we know these concepts, we can sort the phrases into the appropriate bins.

a. decreases the surface area of the plasma membrane. ENDOCYTOSIS, because the new vesicles are formed using the cell membrane

b. requires fusion of vesicles with the plasma membrane. EXOCYTOSIS, because vesicle needs to fuse to the cell membrane to release the carrying material

c. forms vesicles from inward folding of the plasma membrane. ENDOCYTOSIS. Refers to the invagination process of the cell membrane. It only occurs during endocytosis

d. transported substances never physically cross the plasma membrane. BOTH. Substances are too big or too many to be physically transported through the cell membrane

e. increases the surface area of the plasma membrane. EXOCYTOSIS. Occurs when the vesicle fuses the cell membrane to release the content to the exterior.  

f. requires cellular energy. BOTH of them, because they are active transport.

g. secretes large molecules out of the cell. EXOCYTOSIS. The direction is from the interior of the cell to the exterior. These are exportation molecules.

A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?

Answers

Answer:

The correct answer is - blue and red both.

Explanation:

Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.

Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.

Some cells can die as a result of external agents suck as poison or trauma. However, most cells die through a process known as apoptosis, or programmed cell death. What is a likely consequence of a mutation that prevents apoptosis

Answers

Answer: A tumor

Explanation:

A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.

What is apoptosis?

A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.

When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.

Answers

Answer:

A.) a mold... ur welcome

The shape of an organism preserved in rock is called an imprint, which is present in Option C, when an organism dies and is preserved in rock, it may leave behind an impression or imprint of its shape .

What exactly are imprints?

Imprints are formed when an organism's body leaves an indentation in soft sediment, such as mud or sand, before it is buried by additional sediment, as the sediment compacts and hardens into rock over time, the imprint of the organism's shape is preserved, and this type of fossilization is called "external mold," which can provide valuable information about the shape, size, and structure of ancient organisms such as footprints, trackways, and burrows.

Hence, the shape of an organism preserved in rock is called an imprint, which is present in Option C.

Answers

The blue glass filter absorbed most of the red light waves and allowed only the blue light waves to pass through, resulting in the appearance of the rose and the background being different in the two pictures.

What is Light?

Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in straight lines and has both wave-like and particle-like properties. Light is a fundamental part of our world and plays a crucial role in our lives.

Light is produced by the motion of charged particles, such as electrons, and can be emitted by sources such as the sun, light bulbs, and fires. Light travels at a constant speed of approximately 299,792,458 meters per second in a vacuum, which is known as the speed of light.

When Matt took the first picture of the rose on a piece of paper without any filter, the camera captured the visible light waves that were reflected by the rose and the background. The rose appeared bright red because it reflects mostly red light waves and absorbs other colors, and the background appeared white because it reflects all the visible light waves equally.

What are resources a living thing needs to survive? Are these resources limited or unlimited?

Answers

Answer:

The basic resources a living organism needs to survive are sustinence, shelter, and heat. Sustinence is not an unlimited source and wild animals have to hunt to get their food, and if they hunt too much, the food chain will fall out of balnce to where there is no more of that species.

Shelter or safe homes can also be limited, from animals that find natural spots, or make their own homes out of resources, it can be difficult to not be constantly exposed to the natural environment.

Heat is dependant on climate, and is provided by the sun. Nonetheless, in the winter, it isn't reliable, and in the summer, animals may overheat. In conclusion overall, all of these resources are limited or depending on such circumstances.
