Answers

Answer:

True

Explanation:

Organic matter in the soil is called "humus". It is formed by the decomposition of plant material by microorganisms.

It is extremely important for retaining water and nutrients in the soil, both of which are crucial for plant growth and survival. Therefore, organic matter in the soil makes the soil much more "productive."

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?

Answers

Answer:

Find the explanation below.

Explanation:

When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.

Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.

Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.

Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

With respect to one another, galaxies have been found to be
1. moving closer together
2.moving farther apart
3.moving in random directions
4.stationary​

Answers

The answer is moving farther apart

With respect to one another, galaxies have been found to be moving farther apart from each other. The correct option is 2.

What are galaxies?

Galaxies are large areas that contain stars, dark matter, dust, interstellar gases, etc. It is a gravity-bound system that contains everything in its own place.

There are many galaxies, some are still undiscovered. Our galaxy in which the earth is present is called the Milky Way. It is called the Milky Way because due to many stars it looks like a shiny white path.

Now, the Big Bang Theory says that the universe is made up of expanding of a single point. And the universe is still expanding, so the galaxies' and other matters still going farther away.

Thus, the correct option is 2. Moving farther apart.

B.) Two study sites with fluctuating water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles

C.) Two study sites with the same temperature profile, different coral communities growing at different depths, with different water nutrient profiles

D.) Two study sites with stable differing water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles

Answers

It’s d because it makes the most sense

The statement that reveals the best study designs and may yield the most conclusive results is as follows:

Two study sites with stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths.

Thus, the correct option for this question is A.

What is Hypothesis?

In experimental biology, the hypothesis may be defined as a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon. It is basically an assumption that is made based on some evidence.

According to the context of this question, the hypothesis that best demonstrates the most conclusive results for the above experiment is the stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths. This is because the depths of the coral may vary with respect to the nutrients available in an aquatic ecosystem.

Therefore, the correct option for this question is A.

B.38 ATPs.

C. 2 ATPs.

D. 24 ATPs.

Answers

Cellular respiration uses one glucose molecule to produce a total of 38 ATPs (option B).

What is cellular respiration?

Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.

Cellular respiration occurs in three processes namely;

Glycolysis; this is the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source.

Krebs cycle; this is a series of enzymatic reactions that occurs in all aerobic organisms; it involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.

Electron transport chain; this is a series of electron transfer that results in the synthesis of large amount of energy.

In total, the overall process of cellular respiration results in the formation of 38ATPs.

What are the reactants and products of the light independent reactions?​

Answers

Answer:

In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.

The reactants and products of the light-dependent reactions of photosynthesis would be as follows:

Reactant: water, radiant energy, ADP, and NADP+

Products: oxygen gas, ATP, and NADPH

In the light reaction, radiant energy excites the electrons of chlorophyll molecules. The excitation causes the electrons to be knocked off the chlorophyll molecule and the energy of the electrons is used to convert ADP to ATP and NADP+ to NADPH.

The space left by the excited electrons is filled by electrons from water molecules with oxygen from the water molecule being released as a result.

b) How does the thermal energy of solid water change as it melts?

Answers

When ice melts, it’s temperature remains constant until all the ice turns to water.

Answer:

Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

true or false? diffusion is a result of the random movement of particals

Answers

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. However, diffusion can still occur in the absence of a concentration gradient. Diffusion requires energy input from the cell. ... Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration. - Passive transport is the diffusion of substances across a membrane. - Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific proteins. Concentration gradient, size of the particles that are diffusing, and temperature Examples of diffusion in living organisms

Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli. What determines the direction of any diffusion process? The relative concentration of the substance in different areas determines the direction of diffusion. Diffusion occurs from regions of high concentrations to regions of low concentration. What determines the direction of any diffusion process?

PLEASE ANSWER ASAP. Thank you. QUESTION: Explain the evidence that suggests that the universe is expanding.

Answers

One piece of evidence that proves that the universe is expanding is that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. In fact, Hubble discovered that the farther away a galaxy is, the faster it is moving away from us. Although scientists today still don’t know the nature of this mysterious energy causing this acceleration, Hubble’s evidence has strengthened many theories about the large-scale structure of the universe.
