Answer: Those questions that can be answered using experimentation procedures and observations can be answered through science and those that cannot be answered by experimentation cannot be answered through science.
Explanation:
1. It cannot be answered through science because right or wrong to use genetic engineering may be dependent on other parameters like ethical basis.
2. This can be answered through science. This can be answered while placing the resistant species to insects and observing the effect.
3. This cannot be answered through science. This can be answered on qualitative comparison which does not require scientific experimentation.
4. This can be answered scientifically by tracing the primitive life forms and using the residues to develop a new organism with the help of biotechnology.
5. This cannot be answered through science. This is because social factors must be looked upon to understand how they are responsible for producing accomplished artists.
6. This can be answered through science by analyzing the fossil record with respect to the strata were they were found beneath the earth.
As a cell becomes larger, its volume __________. A. stays the same in relationship to its surface area B. increases much faster than its surface area C. increases much slower than its surface area D. decreases much faster than its surface area
Answer:
I would think it would increase faster than the surface area because the volume is the whole cell and the surface area is just the outside.
Explanation:
Hope this helps, have a good day! :)
(Brainliest would be appreciated?)
As a cell becomes larger, its volume stays the same in relation to its surface area. So the correct option is A.
What is cell division?There are two types of cell division. These are mitosis and meiosis. Most of the time when people talk about cell division, they are referring to mitosis. This is the process of the formation of new body cells. Meiosis is another kind of cell division that results in the formation of egg and sperm cells.
Mitosis is the fundamental process of life. During the process of mitosis, a cell duplicates itself along with all of its contents. This includes the chromosomes of the cells. Then the cell splits to form two identical daughter cells.
All the steps of mitosis are carefully controlled by certain genes because of the critical nature of this process. When mitosis is not being regulated correctly, various health problems such as cancer can arise.
Meiosis is the next type of cell division. This ensures that humans have the same number of chromosomes in each generation. Meiosis is a two-step process that reduces the chromosome number by half, from 46 to 23, to form sperm and egg cells. This is also called the reduction division.
Therefore the correct option is A.

What is heart attack? What are its causes?
Answer:
MEANING
A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.
A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks.
CAUSES:
Chest Pain, Pressure, Fullness, or Discomfort.
Discomfort in other areas of your body.
Difficulty breathing and dizziness.
Nausea and cold sweats.

A tick and a dog have this type of relationship?
*mutualism
*commensalism
*neutralism
*parasitism
Answer:
Parasitism
Explanation:
First, let's define each term.
Mutualism: A symbiotic relationship where both organisms benefit
Commensalism: An association where one organism benefits, and the other is not harmed or benefited.
Neutralism: 2 organism interact but they have no effect on each other.
Parasitism: A symbiotic relationship where a parasite lives in or on another organism and harms the organism.
A dog and a tick are an example of parasitism. The tick lives on the dog and drinks the dog's blood. This is the food for the tick, so the tick is benefiting by gaining a food source. The dog can be harmed if the tick is carrying a disease, such as Lyme disease.
Give one reason Mendel chose pea plants for his experinment
Answer:
Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable. These characteristics make pea plants ideal in the study of genetics and heredity.
Explanation:
hope this helps you :)
Answer:
see below
Explanation:
Mendel chose pea plants for his experiments because they have easily identifiable traits like pea plants are either tall or short, which is an easy trait to observe. Also, pea plants grow quickly, so he could complete many experiments in a short period of time.

Which of the steps of cellular respiration occur IN the mitochondria? Choose ALL that apply. A) Krebs Cycle B) Glycolysis C) Electron Transport Chain
Answer:
The answer is option A
Kreb's cycle take place in mitochondria
Whereas electron transport chain in the inner membrane
And glycolysis occurs in cytoplasm
Explanation:
The steps of cellular respiration that occur in the mitochondria are:
A. Krebs Cycle
C. Electron Transport Chain
Cellular respiration can be defined as series of metabolic reactions typically occurring in all living cells, so as to produce energy in the form of adenosine triphosphate (ATP).
Basically, there are three (3) main steps involved in cellular respiration and these include:
GlycolysisKrebs cycleElectron transport chainKrebs cycle is an aerobic reaction that occur in the mitochondria of both prokaryotic and eukaryotic cells and in the presence of oxygen, to produce carbon dioxide (), two (2) adenosine triphosphate (ATP), six (6) NADH, and two (2) FADH.

A new development involves a network of plastic tubes being printed within an organ. After the whole organ is printed, these plastic tubes are dissolved, leaving a network of empty tunnels.
Why does the organ need to have the empty tunnels within it?
Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply for the organ.
In summary the tunnels provided a vascular structure to support the organ

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
A.) ATP is used for long-term storage, while fat and starch are used for immediate energy.
B.) ATP is used for short-term energy and to build molecules of starch and fat.
C.) Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
D.) Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage
Answer:Cells use fat and starch for long term energy storage instead of ATP molecules because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time. ATP is mainly used while doing short bursts of exercises. Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly.
Explanation:
Answer:
ATP is used for short-term energy and to build molecules of starch and fat.

Describe what occurs between water molecules in hydrogen bonding. Draw a diagram, labeling the hydrogen bond.
Answer:
The molecules are attracted to their less negative side.
Explanation:
The Oxygen in the water molecule will share or the hydrogens lone atom leaving the hydrogen with a more positive charge like in the picture I've added. This happens with all water molecules leaving the oxygen with more electrons and ultimately the more negative side. And positive and negative forces attract, so the now "positive" hydrogens will bond with the now "negative" oxygens. They form bonds using polarity, and use a very strong dipole dipole effect.
Some adaptations, on the other hand, become useless. These adaptations are vestigial: remaining but functionless. Whales and dolphins have vestigial leg bones, the remains of an adaptation (legs) that their ancestors used to walk. Why did the author include this selection?
Answer:
This is because vestigial parts are usually homologous to most of the structures that are functional in other species of organisms. E.g.. the Vestigial legs which are non functional in whale and Dolphins, are useful to other organisms. Hence, if these organisms possessed these structures, they should share certain characteristics with each other.Therefore these organisms can be said to evolved from one another.Thus their vestigial organism should be included by the author as evidence of evolution.
