Answer:
I believe D!!
Explanation:
hope this helps :)
The feedback that controls the blood pressure has ben the dropping of blood pressures has been mediated to the slowly decrease the volume of blood flowing. Thus, option C is correct.
What is blood pressure?The pressure of the blood in the circulatory system is often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
Heart failure is common in patients with high pressure. The body’s blood pressure is a measure of the pressures within the cardiovascular system during the pumping cycle of the heart.
In this case, the higher the cardiac output, the higher the volume of the blood in the vessels. Therefore, this increases the pressure in the vessels.
So, that when blood pressure drops, receptors in blood vessel walls tell the heart to beat more slowly to decrease the volume of the blood flowing. Thus, option C is correct.

Biome Description Biome Name
This biome is characterized by long, cold winters. Plants living in this biome are adapted to the short summer growing season. Decomposition in this biome is slow, because of these low temperatures, high soil acidity, and a deep layer of needles from evergreen trees. ________________
In this biome, very little plant litter builds up on the ground because of the hordes of decomposers living here. Under these uniformly warm and humid conditions, the nutrients that are released by decomposers allow for quick uptake by producers, resulting in lush vegetation. ___________________
Although the average annual precipitation in this biome is quite high, rain falls only during certain times of the year. Grasses and widely scattered clumps of trees are the predominant vegetation, and they are well adapted to surviving alternating cycles of dry heat and heavy rains. _________________
Drought-resistant perennial grasses are the dominant vegetation in this biome, as there is sparse annual precipitation. Periodic natural fires, grazing, and drought typically eliminate most seedlings (which adds to the rich organic composition of the soil). Today, much of this land is devoted to farming, with annual crops such as corn and wheat replacing the natural perennial grasses. __________
The characterization of each biome is as follows:
Biomes that are characterized by long, cold winters and are adapted to the short summer growing season: Temperate deciduous forests. Biome that has uniformly warm and humid conditions, the nutrients that are released by decomposers allow for quick uptake by producers: tropical forests. Biome that has the annual precipitation is quite high rain falls only during certain times of the year. Grasses and widely scattered clumps of trees are the predominant vegetation: Savannah.Biome that has a drought-resistant perennial and much of this land is devoted to farming, with annual crops such as corn and wheat replacing the natural perennial grasses: Temperate grasslands. What is Biome?A biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, a biome is characterized as a very large area that is significantly characterized by a particular type of vegetation. Some examples of biomes are tropical rainforests, coral reefs, grasslands, etc.
Temperate deciduous forests have an average rainfall of 75 to 200 cm/year and a temperature of 12 degrees Celcius. Tropical rainforests feel higher rainfall and temperature ranging from 25 to 29 degrees Celcius.
Therefore, the characterization of each rainfall is well described above.

Answer:
The answers are:
carrier proteins → charged amino acid
Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.
osmosis → water molecule
A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.
active transport → calcium moves from low concentration to high concentration
This is the movement of substances across membranes against concentration gradient.
simple diffusion → oxygen
Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.
exocytosis → proteins from the Golgi apparatus
This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.
Explanation: Boom
Carrier Proteins is Charged Amino Acid, Osmosis implies to Water Molecule, Active Transport - Calcium moves from low concentration to high concentration, Simple Diffusion - Oxygen, and Exocytosis - Protein from the Golgi Apparatus.
In assisted diffusion, a type of transport in which charged amino acids or other molecules bind to particular carrier proteins in order to traverse the cell membrane, carrier proteins are involved.
The passage of charged amino acids through the membrane is aided by this mechanism.
Osmosis is the flow of water molecules over a membrane that is selectively permeable, caused by variations in solute concentrations.
The movement of substances against a gradient of concentration, usually from a region of lower concentration to one of greater concentration, is referred to as active transport.
In this instance, calcium ions are actively moved utilising ATP energy from low concentration to high concentration areas.
Simple diffusion is the gradient-driven passive migration of molecules from a region of higher concentration to a region of lower concentration.
Due to their small size and nonpolarity, oxygen molecules can freely diffuse through the cell membrane through simple diffusion.
Exocytosis is the process through which cells discharge big molecules, such proteins, to the exterior of the cell from the Golgi apparatus.
The proteins are contained in vesicles that join the cell membrane and discharge their contents outside of the body.
Thus, charged amino acid transport is facilitated by carrier proteins, water molecules are moved by osmosis, calcium is moved against its concentration gradient by active transport, oxygen is moved along its concentration gradient by simple diffusion, and proteins are released from the Golgi apparatus through exocytosis.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.

Hi, guys so I'm doing an experiment and need help finding out the types of variables. In my experiment, I am using a narrow straw, a wide straw, and some colored water to find out how different variables affect capillary action. I'm trying to find out what is the controlled variable, independent variable, and dependent variable.
Answer:
Controlled variable=coloured water
Dependant variable=amount of water
Independant variable=narrow and wide straw
Explanation:
Have a nice day
Answer:
The controlled variable is straws. Independent it the water and dependent is the capillary action.
Explanation:
The Independent variable is the water because its not chaninging thorughout the experiment and has no conqueunces on the other varibales. The controlled is the straws because you are controlling the different diameters in which the straws are (narrow/wide). Then as you change your controlled variable your dependent varible will change- which is the affect on capillary action.
Hope this helps.
