Name the 6 roles of proteins in the body.
Answer: 1. Repair and Maintenance
Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein.
2. Energy
Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.
3. Hormones
Protein is involved in the creation of some hormones. These substances help control body functions that involve the interaction of several organs. Insulin, a small protein, is an example of a hormone that regulates blood sugar. It involves the interaction of organs such as the pancreas and the liver. Secretin, is another example of a protein hormone. This substance assists in the digestive process by stimulating the pancreas and the intestine to create necessary digestive juices.
4. Enzymes
Enzymes are proteins that increase the rate of chemical reactions in the body. In fact, most of the necessary chemical reactions in the body would not efficiently proceed without enzymes. For example, one type of enzyme functions as an aid in digesting large protein, carbohydrate and fat molecules into smaller molecules, while another assists in the creation of DNA.
5. Transportation and Storage of Molecules
Protein is a major element in transportation of certain molecules. For example, hemoglobin is a protein that transports oxygen throughout the body. Protein is also sometimes used to store certain molecules. Ferritin is an example of a protein that combines with iron for storage in the liver.
6. Antibodies
Protein forms antibodies that help prevent infection, illness and disease. These proteins identify and assist in destroying antigens such as bacteria and viruses. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells.

What chemical compound is responsible for the rotten egg smell that is
typical of seal farts?
Hydrogen disulphide
Hydrogen monoxide
Hydrogen peroxide
Hydrogen chloride
Answer:
Hydrogen disulfide
Explanation:
Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.
It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.
Answer:
Hydrogen monoxide
Explanation:
It is very toxic to smell in farts
Distinguish between an antibiotic and a pathogen.
An antibiotic is designed to kill bad cells to help aid illnesses. However, a pathogen is like a virus or a bacteria that can give a disease. Doctors observe pathogens on a atomic and cellular level to alienate the pathogens weaknesses and what does or doesn't kill it. An antibiotic is commonly used to kill these pathogens and prevent infections.
Basically, the big difference between an antibiotic and a pathogen, is that an antibiotic is used as a source of protection and a pathogen is a seperate living virus (disease). Both are key components of finding cures for harmful viruses and illnesses.

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
Hope this helps!
What process is taking place in the image below?
You can see in this particular structure, there is a hydrogen bond between a hydrogen on the hydronium ion and the oxygen on the other water molecule.
Hydronium ions don’t exist in on their own, they’re required to have some way of balancing the charge that comes from the additional hydrogen ion. This balancing is typically done by the water surrounding the hydronium ion (H3O+H3O+) since water will outnumber the amount of hydronium atoms by orders of magnitude (there’s a lot more water than ions).
The hydronium ion in cold water is typically surrounded by 6 water molecules (probably oxygen towards the extra hydrogen but I can’t access the journal to confirm). There are some other structures like the one above, and another called the Eigen cation where the hydrogen is at the center of four water molecules (one is technically the hydronium). There’s also a very large structure that’s called the magic structure that has a hydronium ion surrounded by twenty water molecules (it’s called magic because it’s extra stable for its size).

Are stars able to adapt to their environment? ANS can stars in the space respond to their changes and reproduce? Pls HELP. NEED FOR BIO
Answer:
Yes. Stars can adapt to their environment. And yes, stars can reproduce when the environment changes.
Explanation:
Answer: Stars are not living organisms. They do not reproduce. In a way, they are their own environment.
Explanation: Living organisms are made of the same "stuff" as the stars, and we depend on our star, the Sun, for energy. But the Sun can not reproduce another sun. It doesn't adapt. Forces of gravity within the galaxy and in the universe determine where stars travel, and their mass and temperature determine how long they will keep shining.

What often results in a woodland frequented by fire?
A. An understory of oak trees
B. A predominance of slow-growing trees
C. A predominance of pine trees
D. Barren land
SUBMIT
The one that results in a woodland frequented by fire is predominance of slow-growing trees. The correct option is B.
What is woodland?A forest is frequently also referred to as "woodland." But most frequently, the phrase is used by geographers to refer to a forest with an open canopy.
The topmost layer of vegetation in a forest is called the canopy. The crowns, or tops, of trees make up this structure.
Woodland contains a wide variety of plant and animal habitats, some of which need management to be created and maintained.
The complete spectrum of plant life, including trees, shrubs, climbers, perennial herbs, bulbs, grasses, sedges, mosses, and lichens, make up woodland.
Predominance of slow-growing trees is the factor that leads to a woodland that experiences frequent fires.
Thus, the correct option is B.

The Roberts family have had a large family garden for several years. Every autumn, after the first frost, they pull up the dead plants
and cover the garden rows with black plastic. When it is spring and planting time, they plant seeds though holes they have poked in
the plastic. Why do the Roberts use the plastic covering?
A)
The black plastic keeps the weeds from growing in the bare soil.
B)
The black plastic keeps the soil warm so the seeds will grow in the spring,
The black plastic helps the organisms that live in the soil survive the
winter
D)
The garden space will be covered with grass and animals will graze in the
area.
Answer:
ANSWER IS A
Explanation:
A black plastic mulch conserves soil moisture by preventing it from evaporating. Only the exposed soil in the holes where the vegetable plants are growing lose water to evaporation. This means that more moisture is available in the surrounding soil for plant roots, and you spend less time on watering the growing crops.
Explain why the Roberts family uses plastic covering.
Autumn is the season when trees lose their leaves. That is the reason Roberts family pull up the dead plants and cover the garden rows with black plastic.Spring is the season of planting. It is a season when plants spring from the ground and trees come into blossom, following winter and preceding summer.The plastic covering prevents weeds from growing on the bare soil.Weeds are unwanted plants grown at a place at a period of time. Any plants that grows where it is not wanted is weed.Therefore,
The reason why the Roberts family uses plastic covering is because "The black plastic keeps the weeds from growing in the bare soil".
