Which is endocrine function?
A. Pyloric glands release mucus to the stomach
B. Adrenal glands release adrenaline into the blood.
C. Esophageal glands release mucus into the esophagus
D. Salivary glands release saliva into the mouth
Answer:B. Adrenal glands release adrenaline into the blood.
Explanation:
The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones
Adrenal glands are a type of endocrine glands that release hormones that include adrenaline into the blood. Thus, the correct option is B
Endocrine glands secrete their products directly in the surrounding interstitial fluid or blood, and not through ducts.
Adrenal glands are a pair of endocrine glands that are present superior to each kidney. It comprises of two distinct regions - adrenal cortex and adrenal medulla.
Adrenal cortex is the outer region of the adrenal gland that produces and secretes hormones like mineralocorticoids, glucocorticoids and androgens.
Adrenal medulla is the inner region of the adrenal gland and produces and secretes the hormones adrenaline and noradrenaline.

what organisms are prokaryotic
Describe the term "semi-permeable" (or "selectively-permeable) membrane. Why is it important?
Answer:
A semi-permeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. Depending on the membrane and the solute, permeability may depend on solute size, solubility, properties, or chemistry. How the membrane is constructed to be selective in its permeability will determine the rate and the permeability. Many natural and synthetic materials which are rather thick are also semipermeable. One example of this is the thin film on the inside of the egg.
Explanation:
An example of a biological semi-permeable membrane is the lipid bilayer, on which is based on the plasma membrane that surrounds all biological cells. A group of phospholipids (consisting of a phosphate head and two fatty acid tails) arranged into a double layer, the phospholipid bilayer is a semipermeable membrane that is very specific in its permeability. The hydrophilic phosphate heads are in the outside layer and exposed to the water content outside and within the cell. The hydrophobic tails are the layer hidden in the inside of the membrane. The phospholipid bilayer is most permeable to small, uncharged solutes. Protein channels are embedded in or through phospholipids, and, collectively, this model is known as the fluid mosaic model. Aquaporins are protein channel pores permeable to water. Information can also pass through the plasma membrane when signaling molecules bind to receptors in the cell membrane. The signaling molecules bind to the receptors, which alters the structure of these proteins. A change in the protein structure initiates a signaling cascade. The G protein-coupled receptor signaling provides is an important subset of such signaling processes.
Nitrogen fixation is done mostly by....
Answer:
Nitrogen fixation occurs between some termites and fungi. It occurs naturally in the air by means of NO x production by lightning. All biological nitrogen fixation is effected by enzymes called nitrogenases. These enzymes contain iron, often with a second metal, usually molybdenum but sometimes vanadium.

how does atp provide the energy cells need
Answer:
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
ATP provides the energy required by cells by releasing a phosphate group.
ADENOSINE TRIPHOSPHATE (ATP):
Adenosine triphosphate (ATP) is a biological molecule that stores and releases energy for living cells. Structurally, ATP is made up of three components namely: phosphate group, adenine base and ribose sugar. ATP stores energy when a phosphate group is added to an ADP molecule while it releases energy when a phosphate group is released from the ATP molecule to form ADP and inorganic phosphorus (Pi). Therefore, ATP provides the energy required by cells by releasing a phosphate group.Learn more at: https://brainly.com/question/20263891?referrer=searchResults

Are plant cells and animal cells exactly the Same? Explain and give examples.
Answer:
Explanation:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. ... Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Answer:
They are not.
Explanation:
Yes they are both cells but plant cells have organelles that the animal cells don't have. Such as chloroplast, the cell wall, and the central vacuole.
