How are the enzymes that nerve cells produce different from the enzymes that blood cells produce? A. The molecules that nerve cells digest are more complex than those digested by blood cells. B. The genes that are activated in nerve cells are different from those activated in blood cells. C. Nerve cells contain more ribosomes than blood cells. D. Nerve cells contain more mitochondria than blood cells.

Answers

Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

why do our digestive systems produce separate enzymes to digest proteins, fats, and carbohydrates?

Answers

Answer:

The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.

Explanation:

Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.

There are different enzymes, produced in the digestive system, for this purpose:

Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.

The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

Which of the following explains what is happening to the fish population due to the increase in human population?
People are switching to eating more meat Instead, which is increasing the fish supplies.
People are still eating plenty of fish and there are more people, so the supply is being depleted faster.
People are reducing fish consumption as the population increases, so fish are being depleted at a slower rate.
People are eating more fish despite the increase in the population, so the fish supply is being privately farmed.

Answers

Answer:

People are eating more fish despite the increase in the population, so the fish supply is being privately farmed.

Why must an owl
swallow its prey whole?

Answers

Answer:

Owls swallow their prey whole or in large pieces but do not produce enough stomach acid to digest bones, fur, feathers and scales. Because undigested body parts could injure the owl’s intestine, the animal needs another way to deal with that part of its diet. That’s where owl pellets come in. An owl has two stomachs. Most birds can’t chew their food, and owls are no exception. Owls usually swallow their prey whole; they differ from other species of birds because they don't have a crop, the baglike organ used to store food after it has been swallowed so that it can be digested later

oncogene lead to the formation of a tumor? option choices
F ATP production is inhibited.
G Somatic cell growth is inhibited.
H Cell division is unregulated.
J Antibody activity is unregulated

Answers

Answer:

H Cell division is unregulated.

Explanation:

Oncogenes are genes that, when mutated or somehow rendered overactive, cause cells to proliferate uncontrollably. This is a hallmark of cancer.

These genes make proteins with a range of functions, for example, signalling proteins, enzymes, transcription factors. What they have in common is that they promote cell growth and division.

Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyte. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir. Color the reservoir grey and the flagellum black.

The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. Color the eyespot red.Euglena can also gain nutrients by absorbing them across their cell membrane, hence they become heterotrophic when light is not available, and they cannot photosynthesize.

The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm type fashion. Color the pellicle blue.

In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus. Color the nucleus purple, and the nucleolus pink.

The interior of the cell contains a jelly-like fluid substance called cytoplasm. Color the cytoplasm light yellow. Toward the posterior of the cell is a star-like structure: the contractile vacuole. This organelle helps the cell remove excess water, and without it the euglena could take in some much water due to osmosis that the cell would explode. Color the contractile vacuole orange.

Extend your thinking: Biological evolution is the process by which populations of organisms change over time. How could natural selection lead to evolution?

Answers

Explanation:

Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.

Environments change over time, and natural selection acts on the genetic diversity in species. After many generations in this new environment, the current population may not look like their ancestors because natural selection has changed them – they have evolved – to survive in the new environment

Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth

Natural selection could lead to evolution when mutated genes are passed on from parents to offsprings over time. Details about evolution can be found below.

What is natural selection?

Natural selection is a biological process by which living organisms become better adapted and suited for survival and reproduction.

Natural selection occurs in living organisms and over time leads to the evolutionary process.

Therefore, it can be said that natural selection could lead to evolution when mutated genes are passed on from parents to offsprings over time.
