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.

Whats the difference from the first and second law of thermodynamics
Answer:
Explanation:
the first law is the law of conservation of energy which basically means energy can't be created or destroyed in an isolated system.

The pickup truck is the only vehicle accelerating.
The pickup truck is the only vehicle accelerating.
The minivan and sedan are both changing veloc
Answer:
The pickup truck is the only vehicle accelerating.
Explanation:
Acceleration refers to the change in velocity per unit time which means that when the velocity changes, acceleration will be produced and if there is constant velocity of a vehicle so the acceleration will be zero. All three vehicles have same velocity of 15 m/s but the truck has no uniform velocity which means acceleration is produced in the truck while no acceleration is formed by three vehicles.
Answer:
The pickup truck is traveling on a curve in the road
Explanation:
Common sense! The truck is traveling on a curve and therefore will have a change in velocity.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?
The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.
At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.

how does tempature impact air movement?
Answer:
The heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart.
Explanation:
Answer:
As you move higher off the ground, it gets colder *and vice versa*.
Explanation:
When we move off the ground, density is pulled down to the ground due to gravity. Therefore, it gets colder. It's also because of our atmosphere. (Vice versa, of course)
P.S. Density and gravity are also key parts of climate change, keep that in mind.
What type of landscape made up most of the land during the Carboniferous period
Answer:
Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America. The name "Carboniferous" refers to this coal.

B. The starch molecule is made of atoms.
C. Starch is the only type of molecule that provides energy.
D. A starch molecule is made of more than one kind of atom.
Please help! I suck at Science!
Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

James is conducting an experiment to test the effect of insecticides on frogs. He gives one group of frogs 10 cc of the insecticide and 0 cc of the insecticide to the other group of frogs. After 5 days, the effects of the insecticide are collected. what is the independent variable and dependent variable
Answer:
Independent variable: amount of insecticide
Dependent variable: effects of insecticide on frogs
Explanation:
Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.
In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.

What process occurs in Box A?
a. A scheme of cellular respiration. At box A, which is located in the cytosol, glucose turns into pyruvate with release of ATP and electrons carried by NADH.
b. Pyruvate from this stage is used in a cycle in box B, which is located in the mitochondrion.
c. As a result, ATP, CO2, and electrons carried by NADH and FADH2 are released.
d. The electrons carried by NADH and FADH2 from boxes A and B are used in box C (inside the mitochondrion) for transformation of a substance marked D (that comes from the cytosol) into a substance marked E (released to the cytosol) with release of ATP.
Answer:
The process occurring in Box A is Glycolysis
Explanation:
Glycolysis is the pathway by which glucose, a six-carbon molecule is oxidized to molecules of pyruvate, a three-carbon molecule with the release of ATP and electrons which are carried by NADH molecules.
The process occurs in the cytoplasm of cells and requires 10 glycolytic enzymes.
The pyruvate molecules from glycolysis is first oxidized to acetyl-CoA and carbon dioxide molecules. The acetyl-CoA molecules enter the citric acid cycle occurring in the mitochondria and are used up in the production of ATP, CO2, and electrons carried by NADH and FADH2.
The electrons carried by NADH and FADH2 from glycolysis and citric acid cycle are used in the oxidative phosphorylation pathway occurring inside the mitochondrion for transformation of oxygen molecules into water molecules with release of ATP.
