(ANSWER NEEDED NOW PLS!!) your sister claims that
the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?

Answers

I think Yes. Because the stomach is divided into four sections, each of which has different cells and functions. For example the food that you eat contains nutrients that give your body energy. The nutrients from the food consumed should travel from the small branches in your stomach in order to allow the cells to supply the nutrients to the rest of the body.

My sister is right. The stomach has structures in its branches that see to the breakdown of food materials.

The digestive system is the system in the body that takes care of the breakdown of food materials and absorption of nutrients from food. The stomach houses most of the structures in the digestive system.

When food is broken down in the stomach, It is sent to other parts of the body via the circulatory system in the body. Therefore, my sister is right.

APT and photovoltaic cells are simikar because

Answers

The question is incomplete, below is the complete question.

ATP and photovoltaic cells are similar because

A. they are both key components of plant cells.

B. they both produce chemical and electrical energy.

C. they are both key components of solar panels.

D. they both use energy from the sun to separate electrons from atoms.

The correct answer to the question is option D

ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.

Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.

These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.

When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.

In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

A. Monomers of starch are sugars such as glucose.

B. Living things store extra sugars as complex carbohydrates.

C. They contain carbon, hydrogen and oxygen, usually in the ratio of 1:2:1.

D. Carbohydrates are the main component that makes up cell membranes

Answers

Answer:

D. Carbohydrates are the main component that makes up cell membranes

Explanation:

The main component of the cell membrane is a double layer of phospholipids - molecules with a phosphate head and fatty acid tail. Therefore D is incorrect. There are some carbohydrates in the cell membrane, but they are not the main component.

The statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).

Carbohydrates are biopolymers composed of monosaccharide units linked by glycosidic bonds.

Complex carbohydrates (e.g., starch) consist of large branched or unbranched chains of monosaccharides, while simple carbohydrates (e.g., glucose) are monosaccharides.

Complex carbohydrates serve as sources of longer energy storage for the cells, while monosaccharides provide energy quickly.

The main component of the cell membranes are lipids (i.e., phospholipids and cholesterol).

In conclusion, the statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).

B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above

Answers

Answer:

B) A vesicle bud will no longer be pinched off from a membrane

Explanation:

Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.

The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane

A biochemist extracts a molecule from a cell. This molecule catalyzes a chemical reaction. To what class of molecules does it belong?

A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids

Answers

Answer:

proteins create enzymes which speed up reaction

Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.    

How do enzymes catalyze chemical reactions?

The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.

Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.    

Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.

Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.

When you feel cold, there are sensors in your skin that tell the brain you need to warm up. The brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. The movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. Which characteristic(s) of life is being represented during this action?
A) respond to stimuli
B) maintain homeostasis
C) growth and adaptation
D) respond to stimuli and maintain homeostasis

I think it is D because your responding to the cold from stimuli and by creating heat to keep your body the average temperature it is homeostasis.

Explain how scientist measure geologic time.

Answers

The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks. They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth.

Answer: Layered rocks and evolution of life and radiometric time scale based on radioactivity of chemical elements

Explanation:

Two scales are used to date these episodes and to measure the age of the Earth: a relative time scale, based on the sequence of layering of the rocks and the evolution of life, and the radiometric time scale, based on the natural radioactivity of chemical elements in some of the rocks.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being dominant. If true breeding red, long radishes are crossed with true breeding white, oval radishes, what will the offspring look like?

Answers

Answer:

The offspring will be purple and long

Explanation:

Radish flowers = Red, purple, or yellow

For a cross between a red-flowered plant and a white-flowered plant to yield all-purple offspring, that means either the red or white is dominant and the other recessive.

When cross it will result in 16 progenies.

Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.

There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
