Define hydrophilic.
How does that change the relationship that phospholipids have to water?
What is the function of steroid? Give an example of a steroid.

Answers

Answer 1
Hydrophilic (water-loving) or could be called water, it mean attracting water molecules as close as possible, the phospholipid is made up of a head that is polar, and a tail that is non polar or in another words called “hydrophobic” , this means that the head of the phospholipid is attracted to water molecules ( this helps you understand the structure of cell membrane formation). Steriod, a class of lipids, some hormones like cholesterol are made up of steroids. They maintain fluidity of cell membrane. Example: oestrogens

(c) Joseph puts a small amount of water into a flat dish in Diagram 1.

Diagram 1

He then leaves the dish outside in the warm sunshine. After a while the water disappears. Explain what happens to the water particles.​

Answers

the water particles evaporate. this is because heat increases the kinetic energy of molecules. causing them to become lighter and rise to the top of the liquid. further heat then breaks the bonds between the water molecules hence allowing them escape.

Why do living things need water, food, and space to live? To maintain homeostasis.

Answers

1.)Food- Food gives organisms energy and the raw materials needed to carry on life processes. Organisms use nutrients from food to replace cells and build body parts.

2.)Water- You could only survive for about three days without water. You get water from the fluids you drink and the food you eat.

3.)Air- Air is a mixture of several different gases, including oxygen and carbon dioxide. Most living things use oxygen in the chemical process that releases energy from food. Oxygen may come from the air or may be dissolved in water.

4.)Habitat- All organisms need a place to live that contains all of the things they need to survive. Some organisms, such as elephants, require a large amount of space. Other organisms may live their entire life in one place.

if your leg was to get cut off where would you feel the pain?

Answers

The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.

Hope it helps you... pls mark brainliest if it helped you

Answer:

The nerve(s) in your leg.

Explanation:

It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

A placebo is a fake treatment that mimics the experience of the experimental group.
true
false

Answers

Answer:

true

Explanation:

Doctors (or scientists) usually use this to make sure people aren't lying about the experience.

For example, some people might expect that if they take ibuprofen or Tylenol, they won't feel as much pain, so they might make themselves believe that they aren't feeling said pain. If you use a placebo group, you are less likely to have situations like that occur, and so your data becomes more accurate.

how does the liver help in maintaining homeostasis

Answers

Answer:

The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.

Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.  

Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.

____________________________________ use reduced, preformed organic molecules (usually from other organisms) as carbon sources, obtain energy from the oxidation of organic compounds, and use reduced organic compounds as their electron source.

Answers

Answer:

Heterotrophs

Explanation:

Heterotroph, in ecology, is an organism that consumes other organisms in a food chain. They acquire their energy by the controlled breakdown of preexisting organic molecules, or food.

¹All heterotrophs, use organic materials as their sole source of carbon. Heterotrophs use preformed organic compounds as their source of carbon. (Source: Brittanica)

Metabolic cycles in general—the extraction by organisms of useful ²energy and food molecules from environmental source material—can be described in terms of oxidation-reduction reactions

Heterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, lithoheterotrophs use inorganic compounds, such as ammonium, nitrite, or sulfur, to obtain electrons.

3. True

-Acids are molecules that give away a type of subatomic particle

4. False

-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.

5. False

-An isotope is an atom that has gained an extra neutron.

What is rough Endoplasmic reticulum?

Rough endoplasmic reticulum (RER), series of associated leveled sacs, part of a nonstop film organelle inside the cytoplasm of eukaryotic cells, that assumes a focal part in the blend of proteins. The unpleasant endoplasmic reticulum (RER) is so named for the presence of its external surface, which is studded with protein-orchestrating particles known as ribosomes.

This element separates it hastily and practically from the other significant sort of endoplasmic reticulum (emergency room), the smooth endoplasmic reticulum (SER), which needs ribosomes and is associated with the union and stockpiling of lipids. RER happens in both creature and plant cells.

What is a pedigree?

Pedigree represents the heritable phenotypic trait in the form of charts and diagrams. Cystic Fibrosis disease is inherited by the autosomal recessive alleles and is possible only if the genotype is ff.

The genotype for the woman being normal should not have recessive alleles and only can be heterozygous or purebred dominant. It is possible only if the genotype is Ff and ff.

Therefore, the genotype of the indicated woman will be Ff and ff.
