Organisms that get their energy by eating other organisms are called _______. A. producers.
B. consumers.
C. predators.
D. prey.

Answers

Answer 1

Answer: consumers.
Producers make the energy themselves (like plants) - if I remember correctly.
Prey are the hunted organisms.
Predators are like hunters who eat other organisms but the correct terminology used in food chains is usually consumers - primary and secondary etc. (again if I remember correctly).

Answer 2

Answer: consumers as they consume generally producers

Acupuncture is an alternative medicine that uses wire-thin needles inserted by a trained practitioner into specific points in the body. This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allow pain to travel within the body. This practice became more widely recognized and used after a New York Times reporter wrote in 1971 of a positive experience with it after surgery. Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce

Doe protein make up 90% of our body weight?

Answers

No. Protein is an important component of every cell in the body. Hair and nails are mostly made of protein, the body uses protein to build and repair tissues as well as to make enzymes, hormones, and other body chemicals. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

Coral bleaching occurs when a colony of polyps are under stress.
a. True
b. False

Answers

Coral bleaching indeed occurs when a colony of polyps is under stress.
Coral bleaching is the loss of endosymbiont's intracellular due to the explosion of the pigmentation of the algae. When the colony of polyps is under stress, it causes the polyps to expel the zooxanthellae from the coral.

The answer is TRUE!!

Which of the following describes the role that enzymes play in the process of metabolism

Answers

Answer;

Enzymes increase the rate of the chemical reactions carried out during metabolism.

Explanation;

-Some enzymes help to break down large nutrient molecules, such as proteins, fats, and carbohydrates, into smaller molecules. This process occurs during the digestion of foodstuffs in the stomach and intestines of animals.

-Other enzymes guide the smaller, broken-down molecules through the intestinal wall into the bloodstream. Still other enzymes promote the formation of large, complex molecules from the small, simple ones to produce cellular constituents.

-Enzymes are also responsible for numerous other functions, which include the storage and release of energy, the course of reproduction, the processes of respiration, and vision.

Enzymes are catalysts of living beings, basically they hurry along chemical reactions and ensure that they happen, hope that helps :)

How does a radio use radiant energy

Answers

Answer Explanation:

A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.

When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.

Electromagnetic waves carry energy

Which cells contain a nucleus and membrane-bound organelles?

Answers

Eukaryotic cells

What Is a Cell with a Nucleus?
When you think of your body, consider the ultimate boss of everything. What organ tells your entire body what to do? The answer is, your brain! Your brain tells your lungs to breathe, your heart to speed up or slow down, and your digestive system to break down food.

All these organs are made of cells. Cells are the basic units of life, and even though they are microscopic they each have a brain of their own. This brain is called the nucleus. The nucleus holds the cell's DNA and controls all cell function. Cells with a nucleus are eukaryotic, and are also known as eukaryotes.

However, not all cells have a nucleus. Some cells have their DNA just floating around the cell. This would be analogous to lower organisms, like worms, that don't have a nice thick skull around their brains. These cells are called prokaryotic. The nuclear envelope in eukaryotes is like our skull, covering the nucleus and keeping the DNA safe.

Eukaryotic cells also have tiny parts called membrane bound organelles. Organelles, like the name sounds, are tiny organs of the cell.

Eukaryotic cells compared to prokaryotic cells
eukaryote versus prokaryote
Like our body has a stomach to digest food, cells have an organelle that serves a similar purpose. These organelles are all contained in a membrane, keeping them separate from the rest of the cell so they can be the most efficient. Let's take a look at some of the common membrane bound organelles and their jobs inside the cell.

Examples of Membrane Bound Organelles
We now know that the nucleus is the brain of the cell, holding the DNA. But other organelles inside the nucleus are also important, just like the other organs in our body are.

A city is another analogy that works for the cell. The city is the cell itself and each organelle is like a building, or part of the city. There is the endoplasmic reticulum, which surrounds the nucleus. This organelle is involved in protein and lipid synthesis, and it's kind of like a factory making the basic parts for the cell.

Those parts are shipped to the golgi to be distributed to the rest of the cell. The golgi is like the post office of the cell. From the golgi, proteins are shipped through vesicles like trucks on a highway, going where they need to be. The plasma membrane might be one destination for those proteins, since it is the outer covering of the cell. The plasma membrane is like the walls of a city, only letting certain things in and out.

The power plant of the cell, supplying energy for the entire city, is the mitochondria. And our cities also need to get rid of waste, right? An organelle called the lysosome breaks down unwanted or old materials in the cell, recycling them for later use. Finally, peroxisomes are important organelles that also do reactions using oxygen and protect the cell from free radicals, or dangerously reactive compounds.

Organelles in an animal cell

Plant cells are a little bit different and have some additional organelles. In plant cells, there is an organelle called a vacuole, which is like a water storage tower in a city. Some animal cells have small vacuoles, but they are not as prominent as they are in plants. This organelle stores water and helps the plant cell hold its shape. Plant cells also have an even more rigid boundary outside the plasma membrane called the cell wall. This thick structure is like reinforcements on our cell wall. They also have chloroplasts, which are used to turn sunlight and carbon dioxide into food.

Organelles inside a plant cell
plant cell
Other organelles don't have a membrane but are still important. Ribosomes are a type of organelle that makes protein and can work with the endoplasmic reticulum. Both prokaryotes and eukaryotes have this organelle.

Eukaryotic cells are cells that have a nucleus and membrane-bound organelles.

Who owns eukaryotic cells?

The humans.
The animals.
The plants.

Eukaryotic cells have a membrane around the nucleus that separates them from the cytoplasm. Inside the nucleus are the nucleic acids and inside the cytoplasm are all the organelles necessary for the functioning of the cells.

Eukaryotic cells are more complex than prokaryotic cells because of their configuration.

Prokaryotic cells, on the other hand, do not have a nucleus, so the nucleic acids are loose in the cytoplasm and are not separated from the other organelles, which in this type of cell are few and less complex than those of eukaryotic cells.
