What is the function of cholesterol?
to keep the cell membrane from falling apart
to line the arteries of organisms
to store energy
to give us quick energy
Answer:
to store energy
Explanation:
Its main function is to maintain the integrity and fluidity of cell membranes and to serve as a precursor for the synthesis of substances that are vital for the organism including steroid hormones, bile acids, and vitamin D. Cholesterol is essential for making a number of critical hormones, including the stress hormone cortisol. Cholesterol is also used to make the sex hormones testosterone, progesterone, and estrogen. 2 The liver also uses cholesterol to make bile, a fluid that plays a vital role in the processing and digestion of fats.
Patterns of inheritance are usually more complicated than what is predicted by Mendelian genetics. Explain four possible exceptions to Mendelian genetics involving the inheritance patterns of a single gene and provide an example of each.
Answer:
Please find the explanation of the four possible exceptions to Mendelian genetics below.
Explanation:
Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:
- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).
- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.
- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.
- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.

Why is sickle cell anemia so harmful to its carriers?
Answer: BECAUSE IT MAKES THE RED BLOOD CELLS SHRINK
Explanation:
Answer:
Sickle cell anemia is harmful to the body because it is enagering your spleen and with less healthy red blood cells circulating in the body, you can become chronically anemic.
Sickle cell anemia puts your body at more risk for infection.
Explanation:
The spinal cord relays messages between the body and the brain. These messages control body functions like movement, bladder and bowel control and breathing. Each vertebra has a pair of spinal nerves that receive messages from the body (sensory impulses) and send messages to the body (motor impulses). The spinal nerves are numbered 1 to 55 from the neck down. The first eight as seen here are the vertebrate and send messages to the back of the head, neck, shoulders, arms, hands and diaphragm. A) cervical B) lumbar C) sacral D) thoracic

What term describes parts of the body that are made from different kinds of cell
Answer:
The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.
Explanation:
The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.
Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.
The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.

Explanation:
1. Negative feedback is bad for your body. True or false 2. Both negative and positive feedback works in a loop. True or false. 3. Feedback loops are open systems of information. 4. There are feedback systems found in the environment and mechanical systems.
Answer:
1. False
2. True
3. True
4. True
Explanation:
Negative feedback (or balancing feedback) happens when some capacity of the yield of a framework, cycle, or system is taken care of in a way that will in general decrease the variances in the yield, regardless of whether brought about by changes in the input or by different unsettling influences.
Though certain feedback will in general prompt unsteadiness through outstanding development, wavering or disorganized conduct, negative feedback for the most part advances steadiness. Negative feedback will in general elevate a settling to balance, and diminishes the impacts of bothers. Negative feedback loops in which the perfect measure of adjustment is applied with ideal planning can be entirely steady, exact, and responsive.

You overhear your mom and dad talking about having a well installed in your yard. What advice can you offer them about determining the placement and potential effectiveness of the well? Think about what you know about how wells factor into the groundwater systems running below the surface of the Earth.
Answer:
Built well where water table present nearer to surface.
Explanation:
My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

As you observe an unknown cell under a microscope, you make the following observations..
Answer:
It is a plant cell that is being observed
Explanation:
With in the cell, there are chloroplasts that ONLY a plant cell has. It also has a cell wall which an animal cell does not, so it is clearly not an animal cell.
A group of researchers wants to develop an experiment to determine whether a new drug effectively treats cancer. The researchers want to inject the drug in hamsters first to determine whether there are any potentially serious side effects.
Part A: What are some possible ethical issues with this type of testing?
Part B: While conducting the experiment, the researchers find cancer stops spreading, and they declare the new drug is responsible. Is this a good assumption? Explain.
Answer:
Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.
Answer:
The current code of ethics to be upheld in science experiments are as follows: the experiment must contain a clear scientific purpose, the animals must be housed and provided with care, the animals must be legally acquired, the least amount of suffering must be ensured, and the animals can only be used when it is entirely necessary.
In this paragraph, we can see the plan does not fit the code of ethics entirely- because this is a new drug, we can not be sure that this experiment will not be fatal for the animals, and that they will not suffer tremendously before passing on. The medicine should be tested first on a sample which is not living.
Explanation:
what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part d
Answer:
What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.
Explanation:
One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.
What could he do to make their work in the lab safer?The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.
Chemical waste is usually taken to a landfill where it can be neutralized. Biological waste is transported to incinerators for complete disposal. Why is it important to follow these procedures?Following these procedures is important to avoid chemical or biological contamination of both the environment and people.
