B. An oak tree grows from the seed material in an acorn.
C. Water drips from underneath an oak tree leaf in the morning.
D. Sediment from an area where oak trees were cut down builds up alongside a stream

Answers

The example that demonstrates that all cells come from pre-existing cells is an oak tree grows from the seed material in an acorn (option B).

What is the cell theory?

The cell theory is the scientific theory that all living organisms are made of cells as the smallest functional unit.

One of the components of the cell theory is that all cells come from already existing cells i.e. new cells form from cells that are already in existence in a process of reproduction.

The example of this is a tree that grow from a germinating seed. Hence, option B is correct.

The anglerfish is a type of saltwater fish with an interesting method of catching prey. It lives deep in the oceans, where both light and food are scarce. A "light" glows on a filament right over an anglerfish's mouth. This glow is created by bacteria that live inside the fish. The bacteria are bioluminescent, which means that they produce light. When other fish see this bright glow—a rare thing in the dark waters—they come close to investigate and eventually become dinner. Anglerfish rely on _________ their food. Options: a. Cultivating b. Defending c. Attracting d. Pursuing

Answers

Answer:

C. Attracting

Explanation:

The "light" attracts prey to the anglerfish.

Explain why the lithosphere is indispensable to life. Give at least two reasons. PLEASE ASAP

Answers

The lithosphere of Earth comprises the crust and the uppermost mantle. The lithosphere consists of separate tectonic plates. The uppermost part of the lithosphere has undergone chemical and physical processes to form a soil layer called the pedosphere. The pedosphere is vital to life on Earth and an intrinsic part of all terrestrial ecosystems. The pedosphere provides a substrate for primary producers, i.e., plants, which are in turn vital for all other life on Earth. The pedosphere is also a vital part of the hydrological cycle, as groundwater feeds streams and soil and groundwater is taken up by plants. 

A complication risk of gastric bypass surgery that bypasses most of the small intestine is ____.​

Answers

The answer would be vitamin and mineral deficiencies.

The small intestine has a role in food digestion and absorption. Bypassing most of the small intestine will reduce the food transit time there, thus reducing the amount of substance that can be absorbed. 
These surgery supposed to help diabetes type 2 patient, not making it worse. It should be not related to kidney or muscle.

Answer: Malnutrition

Explanation: When a surgeon cuts an area of small intestine then the main problem that can be faced is malnutrition.

This is because small intestine is the main organ for the absorption of nutrients in the body.

If it is cut down then the absorption of many nutrients, vitamins an minerals will be affected.

The correct answer is malnutrition.

In cells, hydrogen peroxide is converted to water and oxygen through the activity of

Answers

The right answer is enzymes (catalase).

Catalase is an enzyme that allows the dismutation of hydrogen peroxide (hydrogen peroxide) in water and oxygen.

The oxygen-oxygen bond of the hydrogen peroxide is cut off by the iron atom of the heme group, creating a molecule of water and a highly oxidizing iron-oxygen bond. This can oxidize a new molecule of hydrogen peroxide, giving oxygen. The enzymatic reaction at play is one of the fastest known.

Within the cell, catalase helps protect the body from the oxidative and harmful action of hydrogen peroxide.
In cells, hydrogen peroxide is converted to water and oxygen through the activity of enzymes.

What enzyme is kept in its active form by the presence of vitamin C in the diet? Is prolyl hydroxylase the active form enzyme here?

Answers

yes, Porlyl Hydroxylase

Enzyme productions also depend on the supply of iron and it is crucial in the total development of children who are growing and developing hormones, neurotransmitters, and new cells within their body. If iron stores are low, memory, mood, attention span, and focus are among the effects of the deficiency because oxygen transport in the blood is lessened or diminished.
