Answer:

blue-green algae

Explanation:

Answer:

Bacteria is the biggest example but these are also examples blue-green algae, E. coli, and mycoplasma.

Explanation:

This is what it is: Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

The minivan and sedan are both changing veloc

Answers

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.

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.

Answers

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.

how does tempature impact air movement?

Answers

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.

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?

Answers

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.

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

Answers

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.

The three scientists that contributed to the development of cell theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow
So the answer might be E and B

The scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.

What is Cell theory?

Cell theory was proposed by a German botanist M.J. Schleiden and a German zoologist T. Schwann. According to them, the cell theory states that:

All living organisms whether it is plant or animal is made up of cell.A cell is the smallest unit of all living organisms.The Cell is the structural and functional unit of organisms.

Charles Darwin was popular in the field of evolution. Hence, he is referred to as the father of evolution. Robert Hook was known in order to discover a cell in 1665.

Later in 1855, the cell theory is further refined by German biologist R. Virchow. According to him, all cells are arising from pre-existing cells.

Therefore, the scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
