Please answer asap for chance of brainiest! How would you expect the rate of meat digestion to differ in an animal whose digestive tract had less of the enzyme pepsin?
Answers
Answer:
The four basic types of digestive systems in animals are monogastric, avian, ruminant, and pseudo-ruminant. Monogastric animals, such as swine, eat rations high in concentrates. The avian digestive system, found in poultry, is completely different from the other three types of digestive systems.
Explanation:
The four basic types of digestive systems in animals are monogastric, avian, ruminant, and pseudo-ruminant. Monogastric animals, such as swine, eat rations high in concentrates. The avian digestive system, found in poultry, is completely different from the other three types of digestive systems.
Carnivores or meat eater, digestive system of them is very short because meat is very easy to digest, hence the level of acid in the stomach is high while the digestive system of herbivores are long so their digestion is slow and the level of acid in the stomach is high.
Who are Carnivores and Herbivores?A carnivore is an organism that eats meat, or the flesh of animals. Sometimes they are also called hunters while some prey are called prey. Carnivores are a major part of the food web.
A herbivore is an organism which feeds on plants, ranges from in small size tiny insects such as aphids to large, lumbering elephants to large animals like cow, buffalo . Herbivores are a major part of the food web.
Herbivores eat only plant or plant products like sheep, cow, goat, etc. Carnivores are those who can eat animals only, for example lions, tigers, etc.
Thus, Carnivores or meat eater, digestive system of them is very short because meat is very easy to digest, hence the level of acid in the stomach is high while the digestive system of herbivores are long so their digestion is slow and the level of acid in the stomach is high.

If am elephant were chasing you, it's enormous mass would be very scary .but if you zigalzagged ,the elephant's mass would be to your advantage. why?
Answers
If you zigalzagged ,the elephant's mass would be to your advantage due to inertia.
How zigalzagged would be to your advantage?If you move zigalzagged ,the elephant's mass would be to your advantage because the elephant's mass is greater than yours so due to inertia, the elephant would have more difficulty switching directions than you.

Explain the structure and function of the eye as a sensory receptor including the role of;
A) The cornea and lens
B) The iris
C) Rod and cone cells in the retina
NOTE - the letters listed are NOT answers, they are separate points that need clarifying.
Answers
Answer:
A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.
C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.

Which of the following does water pollution affect: surface water, ground Water, or ocean water? A)Pollution affects surface water and ground water only.
B)Pollution affects surface water, ground water, and ocean water.
C)Pollution affects surface water and ocean water only.
D)Pollution affects groundwater and ocean water only.
Answers
Water pollution includes any kind of water masses or currents. Option B is correct. Pollution affects surface water, ground water, and ocean water.
What is water pollution?
Water pollution can be defined as the abnormal accumulation of strange elements in the water with harmful consequences to natural ecosystems.
Water pollution involves all the possible ways in which any water body can be contaminated with harmful elements.
The most damaging source of water pollution is human activities, producing the biggest damage to natural ecosystems.
Contaminating elements might be either gasses, solid material, or liquid material. Chemical elements, microbiota, heavy metals, and sediments affect all forms of life.
As said before, several sources can contaminate water masses, and they do it directly and indirectly.
Directly pollution occurs when a strange element is thrown directly into the water. They can be thrown directly into a river, a lake, the sea, or the ocean.
Indirect pollution occurs when pollutants travel from other places and contaminate other masses of water. For instance, a polluted river contaminates the lake where it ends. The lake pollutes the river that begins in the lake. This last river ends in the sea and takes all pollutants to the sea.
We can affirm then that water pollution affect surface water, ground water, or ocean water. Option B is correct. Pollution affects surface water, ground water, and ocean water.

A student is investigating the strength of electromagnets she created using batteries, wire, and nails.
She uses two different-sized nails and varies the number of coils of wire around the nail to determine how many paper clips each configuration can lift. She makes a data table of the results.
The student hypothesizes that the number of coils has a cause-and-effect relationship on the strength of the magnetic devices she made. Which would be the best way for the student to test the devices to be sure that her hypothesis is accurate?
Answers
Explanation:
You will change two variables to make different electromagnets: the number of wire coils around the nail (10 or 20) and the number of D cell batteries.
What is the only form of nitrogen that plants can absorb?.
