Answer:

Each is used to break down substances.

Explanation:

Enzymes merely speed up a chemical reaction, not necessarily break down substances.

Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.

Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.

Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).

Thus, the ideal selection is option A.

Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).

The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.

In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.

During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.

Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

Answer:

they are able to produce fertile offspring

Explanation:

A species is a group of organisms that are able to produce fertile offspring. This criterion is the basis of the biological concept of species proposed by Mayr in 1970, who defined a species as a group of genetically similar interfertile populations which are reproductively isolated from other groups. In consequence, only those populations whose individuals can interbreed (mate) with one another to produce viable and fertile offspring must be considered to be part of the same species.

Answer:

The correct answer is - Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins, vena cavae

Explanation:

Throughout the vascular system or cardiovascular system, the drop of deoxygenated blood moves through right atrium and right ventricle to the lungs within the pulmonary arteries. Then the oxygenated blood transfers via pulmonary veins t the left atrium of the heart that pumps the oxygenated to the rest of the body by the left ventricle through the aorta.

Arteries help in the flow of the systemic circulation then blood moves from arterioles to capillaries. The deoxygenated blood is returned through the veins to the heart that come to the superior and inferior vena cava and back to right atrium and cirlculation repeat again.

The major levels of classification are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.Explanation:

Answer:

mutations create a new particular gene, a new allele. If that allele is passed down to the next offspring and the next, the mutation would be carried throughout the population. Some of the species in the population might not show any symptoms of a mutation or not feel the effects of it, but pass it down. If the mutation is neutral (causing no harm or no good), it may be passed down. If the mutation is beneficial to the species, and helps them survive, it may be passed down more. If the mutation is harmful, the mutation may eventually stop being passed down, and start to only appear if something happens genetically (mutation still may happen, but not because of passing down from parent to offspring).

The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.

Explanation:

Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.

Trains also produce pollution but in comparison to cars these are way less contribute to the pollution, However, these are not convenient as they start and reach at a specific time and also sometimes not comfortable like cars.

Answer:

it's ends up somewhere else

Answer:

First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Answer:

Alzheimer's disease.

Explanation:

It is A progressive disease that destroys memory and other important mental functions.

Brain cell connections and the cells themselves degenerate and die, eventually destroying memory and other important mental functions.

Symptoms :

Cognitive: mental decline, difficulty thinking and understanding, confusion in the evening hours, delusion, disorientation, forgetfulness, making things up, mental confusion, difficulty concentrating, inability to create new memories, inability to do simple maths, or inability to recognise common things

Behavioural: aggression, agitation, difficulty with self care, irritability, meaningless repetition of own words, personality changes, restlessness, lack of restraint, or wandering and getting lost

Mood: anger, apathy, general discontent, loneliness, or mood swings

Psychological: depression, hallucination, or paranoia

Also common: appetite loss, difficulty with skilled movement, or paraphasia

there is no cure for Alzheimer's disease or a way to stop or slow its progression, there are drug and non-drug options that may help treat symptoms.

Cause:

Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells.

Answer:

a) The cell dies because it was in a hypertonic medium, and it loses water due to the difference in pressure and may even die from dehydration.

b) To correct this, the cells can first be placed in an isotonic solution (one that has the same concentration of solute as a solution separated or isolated by a semi-permeable barrier). A method to remove the salt is called dialysis.

Explanation:

A protein purification is a series of processes that allow the isolation of protein from mixture. Thereby this process is vital for the characterization of the function, structure and interactions of the protein of interest. It is therefore a very important procedure to perform correctly.

Ammonium sulfate is a salt whose chemical formula is (NH4)2SO4. The cells are in a 2M solution (2 moles of sulfuric acid per liter of solution). This is detrimental because the solution is hypertonic, it has a higher osmolarity in the external medium than inside the cell, so that a cell in such a solution loses water due to the pressure difference, i.e. osmotic pressure, and may even die from dehydration. The outflow of water from the cell continues until the osmotic pressure of the external medium and the cell are equal.

Centrifugation is a method by which solids can be separated from liquids of different density by means of a rotating force. After centrifugation, the supernatant will have a soluble part (proteins) and a pellet (cells and other insoluble parts). Thereby, the protein of interest would be recovered in the supernatant. But since the cell was not previously in a suitable medium, it could not carry out its metabolism and died and could not produce the protein of interest.

a) The cell dies because it was in a hypertonic medium, and it loses water due to the difference in pressure and may even die from dehydration.

b) To correct this, the cells can first be placed in an isotonic solution (one that has the same concentration of solute as a solution separated or isolated by a semi-permeable barrier). A method to remove the salt is called dialysis.

Dialysis is the process of separating molecules in a solution by the difference in their diffusion rates or osmotic pressure across a semipermeable membrane. A solution of various types of molecules is placed in a semi-permeable dialysis bag, such as, for example, on a cellulose membrane with pores, and the bag is sealed. The sealed bag is placed in a beaker with pure water or another solution. Molecules small enough to pass through the pores (often water, salts and other small molecules) tend to move in or out of the dialysis bag in the direction of the lower concentration. However, larger molecules (such as DNA, proteins or polysaccharides) that are larger than the pore diameter are retained within the dialysis bag.
