please help, i’ll mark brainliest if you get it right! please please only answer if you know the answer though, don’t guess i’m taking a test and i can’t fail as it’s the last one before the quarter ends ( tomorrow ) id appreciate it!! thank youuu
Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal
Answer:
Nervous tissue can generate and conduct electrical signals that control the body.
Explanation:
The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.
The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.
The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.
Answer:
Part 1: electrical
Part 2: A, B, E

how do skin cells replace itself after an injury?
a) skin cells go through the process of budding to make new identical cells.
b) skin cells go through the procces of mitosis to make new identical cells.
c) skin cells go through the process og photosynthesis to make new identical cells.
d) skin cells go through the process of cellular respiration to make new identical cells.
Answer:
d
Explanation:
as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration
Answer:
b) skin cells go through the process of mitosis to make new identical cells.
Explanation:
The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.
This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.

What happened when Earth's first atmosphere collapsed? Will mark you as brainliest!
- it created oxygen
-it formed the oceans
-it triggered an ice age
-it fell as rain, watering the earliest plants
Explanation:
solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth's surface.Plants and land animals would die
Which of the following shows a correct base pairing in DNA?
A and G
T and G
C and A
Gand C
Answer: G and C
Explanation: DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine

Where dose plastic come from?
Answer:
Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

What is insulin and why do people with Type 1 diabetes need it to survive?
Answer:
Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy. With type 1 diabetes, beta cells produce little or no insulin.
what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
What is phenotype?A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.
When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
Thus, in this way, phenotype is dependent on genotype of the organism.

container?
Select one:
O
Liquid and gas
O
Gas and crystal
O
Sod and gas
O
Solid and liquid
Answer:
Liquid and gas
Explanation:
Liquid and gases can take the shape of their contains.
Liquids have not fixed shape and they readily flow.
Gases are random and they occupy the contains they fill .
Volume is the amount of space occupied by a substance. Gases can take up any amount of space in a container. Liquids can readily flow and take up spaces too. Solids are fixed and have a definite volume.Can Plastic Waste Degrade Into The Soil?
Yes or no and explain
Answer:
Yes, but the process is too slow
Explanation:
We pack almost everything in this material and plastic has become a very normal occurrence in the modern world. Each year, people used 1.6 million barrels of oil just to make plastic bottles.
On the other hand, nature takes about 1000 years to develop a single plastic object, while plastic material takes about 240 years.

What is the source of oxygen as a reactant in cellular respiration?
Answer:
The Reactants
What goes into the cell? Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.
Explanation:
Hope this helped, Thanks :)
Cellular respiration has been the chemical process that uses glucose to produce energy. Oxygen is the reactant of the process that comes from the air (breathing) produced by photosynthesis.
What is cellular respiration?Cellular respiration has been defined as the process vital for living organisms that use oxygen and sugar molecules to produce energy to drive the activities and functions of the body. The reactant of the process includes glucose and oxygen gas.
Oxygen and sugar are known to be the product of the photosynthetic reaction that uses carbon dioxide and water. The oxygen gas is present in the atmosphere and enters the body through breathing.
Therefore, oxygen acts as a reactant in cellular respiration that comes from the breathing process.
