What will happen to a cell that is placed in a hypotonic saline solution?
1) Salt will enter the cell causing it to swell.
2)Water will enter the cell causing it to swell
3)Salt will exit the cell causing it to shrink.
4) Water will exit the cell causing it to shrink.
Answer:
Salt will enter the cell causing it to swell.
Explanation:
Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst. ... Plant cells have a cell wall around the outside than stops them from bursting, so a plant cell will swell up in a hypotonic solution, but will not burst.
A hypotonic solution is less concentrated than the cell interior. So, when a cell is placed in a hypotonic saline solution, water will enter the cell causing it to swell. Therefore, the correct option is 2.
--------------------------------------
A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane. The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.
As water enters the cell, the cell begins to enlarge and becomes bigger-sized. And because cells can not limit the amount of water moving into it, the cell keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.
Under natural conditions, the body regulates the extracellular fluids to avoid cells swelling until they burst.

The genetic composition of daughter cells produced by mitosis differs from that of the daughter cells produced by meiosis. Describe TWO features of the cell division processes that lead to these differences.
Answer:
plzz mark as brainliest
Explanation: The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.
The main differences between mitosis and meiosis occur in meiosis stage I.
For the most part, in mitosis, diploid cells are partitioned into two new diploid cells, while in meiosis, diploid cells are partitioned into four new haploid cells.
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Meiosis II and mitosis are not reduction division like meiosis I because the number of chromosomes remains the same; therefore, meiosis II is referred to as equatorial division.
When the homologous chromosomes separate and move to opposite poles during meiosis I, the diploid level is reduced from two to one, which is referred to as a reduction division.
TWO features of meiosis are recombination and independent segregation.
Meiosis is a reductional cell division that produces four daughter cells with half of the genetic material.Recombination refers to the interchange of genetic material between nonsister chromatids during meiosis (prophase I).Ramdon segregation refers to the independent process of separation of homo-logous chromosomes during meiosis.In conclusion, TWO features of meiosis are recombination and independent segregation.

a. different from the starting cell and identical to each other
b. identical to the staring cell and different from each other
c. different from the staring cell and different from each other
d. identical to the starting cell and identical to each other
Answer:
D
Explanation:
mitosis creates exact copies of the starting cell
In mitosis the two resulting cells are identical to the starting cell and identical to each other. Therefore, option (D) is correct.
What is mitosis?In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Thus, equational division is another name for mitosis.
Making additional diploid cells is the goal of mitosis. Each chromosome is copied, and the copies are then distributed to the various sides of the cell. In this method, each new cell receives a copy of each chromosome when the cell splits in half.

the phase in the life cycle of a plant that produces spores
Answer:
Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.
Explanation:
Answer:
plants have multicellular haploid and multicellular diploid stages in their life cycle. Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis.

Community leaders are looking for a potential solution to prevent damage from future hurricanes. Below is a list of their concerns as well as how important each issue is to the community. Community Concerns Concern Level Wave action Low Beachfront development Low Nearshore aquaculture Low Health of nearby coral reef Moderate Roosting bird species High Storm surge threat High Which of the following solutions would best address the issues of greatest concern in the community? Construction of a seawall Construction of a seawall A Planting mangrove forests Planting mangrove forests B Construction of an offshore breakwater Construction of an offshore breakwater C Adding large sand dunes
Answer: B, planting mangrove forests
Explanation:
Healthy mangrove forests provide homes for roosting bird species, protect coastal communities from storm surges, and provide a nursery habitat for juvenile coral reef organisms.
A is incorrect because the construction of a seawall would prevent the threat of storm surge but would not provide a habitat for roosting bird species nor help the health of the coral reef.
C is incorrect because the construction of an offshore breakwater would prevent the threat of storm surge but would not provide a habitat for roosting bird species. Its construction would also likely damage the nearby coral reef.
D is incorrect because creating large sand dunes could initially protect from storm surges, but this can also cause erosion. Sand dunes would not provide habitat for roosting bird species nor would they help to protect the health of the coral reef.

How do you think molecules of food rearrange when they react with oxygen in the cells of your body?
Answer:
In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.
Explanation:
The glucose and oxygen atoms are rearranged into carbon dioxide and water molecules during aerobic respiration. Being an exothermic chemical reaction, this process releases energy as it goes along.
What is aerobic respiration?A chemical reaction that converts carbohydrates into energy using oxygen (sugars). also known as oxidative metabolism, aerobic metabolism, and cell respiration.
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise.
As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.
During aerobic respiration, glucose and oxygen atoms are rearranged into carbon dioxide and water molecules. As it proceeds, this process releases energy since it is an exothermic chemical reaction.

What type of compound is water according to its chemical bonds?
Explanation:
Water as a Compound and Molecule
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.
Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier.
Answer: water is a polar molecule
Explanation: water H2O has two covalent bonds between Oxygen and Hydrogen atoms. Both are non-metals and share outer electrons for forming a covalent bond.
Oxygen has much greater electronegativity and it pulls shared electrons with greater force. So bond is polar and because molecule is V-shaped, Oxygen has permanent
Negative partial charge. Also molecule is polar and makes Hydrogen bonds with other water molecules.

Destruction of tropical rain forests: helps maintain global temperatures
reduces the amount of water vapor
increases the amount of condensation
does not affect the water cycle in a significant way
Answer:
B. reduces the amount of water vapor
Explanation:
Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.
One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
