Answer:
Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of food to energy to run cellular processes; the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic.

How does evolution work?
I need a simple answer.
Answer:
evolution refers to cumulative changes that occur in a population over time.
Explanation:
Hope that helps :)
Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.

What kind(s) of eukaryotic cells have mitochondria?
Answer:
Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria. A few types of cells, such as red blood cells, lack mitochondria entirely.

In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."

what two things do produce when atoms bond ?
Answer:
1. Carbon Dioxide
2. Water Vapor
Explanation:
When atoms bond with oxygen in the air it goes through a process called oxidation. When carbon bonds with oxygen, it produces carbon dioxide; a colorless gas. When hydrogen bonds with oxygen, it produces water vapor.

Model of asexual and sexual reproduction.
give me a model of these, i’ll give whatever i can. it’d be a life save. best regards, happy new years.
Answer:
sexual reproduction is where a sperm and egg combine togethe r which is called a zygote. and after couple months turn into a baby(example; us humans) Asexual are things that do not need a mating partner to reproduce such as cells, they can reproduce themselves from 1 to 2 to 4 to 8 to 16 to 32 again and again. I cannot show a model but this summarizes what happens. Hope it helps, if you need a picture you can search them up
What are our lungs made out of?
Answer:
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopies

A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is
the beaker hypertonic, hypotonic, or isotonic to the cell? *
Answer:
Hypertonic solution
Explanation:
Because a hypertonic solution occurs when more solutes are outside the cell than on the inside cell
A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is the beaker hypertonic to the cell.
What is in a hypertonic solution?Any external solution with a high solute content and a low water concentration in comparison to bodily fluids is referred to as a hypertonic solution. The net migration of water in a hypertonic solution will be from the body into the solution.
Hypertonic solutions include 10% salt content. A cell that is placed in a hypertonic environment experiences a net migration of water to the cell's exterior (from the higher water environment inside the cell). In reaction, the cell contracts.
A solution is said to be hypertonic if its salt concentration is higher than the salt concentration in the cells. The osmosis process allows water to pass through permeable cell membranes.

Which statement is correct regarding the semiconservative nature of DNA?
A. RNA operates as a template to allow DNA to replicate itself using ribosomes
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
C. The semiconservative nature of DNA allows for genetic continuity in gamete production
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
I need the answer fast, this is a 40 point and i will put you as brainliest
Answer:
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
Explanation:
DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.
In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.
