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.

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.

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.

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.

Answer:

the largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land. The intertidal zone is where the ocean meets the land — sometimes it is submerged and at other times exposed, as waves and

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.

Answer:

Karotyping is a chromosomal analysis. It can be used to look for diseases caused by irregularities in the chromosomes, such as Down syndrome.

Explanation:

Karotyping is a chromosomal analysis of the chromosomal constitution of the nucleus of a cell, which is equal to the complete chromosomal makeup of a person. The chromosomes of each species have a certain structure both in size, shape and their own band when they are stained in the laboratory. This allows them to be identified as well as to know if all the genetic information is in the correct order. In addition to numerical abnormalities in chromosomes, structural alterations mean that certain chromosomal regions can be duplicated or even absent. This gain or loss of genetic material has highly varied consequences depending on the genes involved. Another type of structural alterations are translocations and inversions. The karyotype can be studied in search of diseases caused by irregularities in the chromosomes, such as Down syndrome. It also helps to identify problems that a baby conceived through assisted reproduction may have when it is born, by extracting the karyotype that is found in the amniotic fluid of the embryo.

Answer:

If the emission of greenhouse gases were stopped, global warming would still happen due to the gases that are already in the atmosphere and the constant deforestation.

Explanation:

Greenhouse gases are the biggest creators of global warming. This is because these gases cause holes in the ozone layer, which protects the planet from the sun's rays. These holes cause the sun's rays to reach the earth's surface with greater intensity, promoting global warming.

Trees are able to absorb these gases, decreasing their concentration in the atmosphere and preventing them from degrading the ozone layer. However, the constant deforestation has reduced the number of plants and the remaining amount on the planet cannot cope with the constant emission of these gases. In this case, even if the emissions of greenhouse gases were ended, the amount of these gases in the atmosphere would still be very large. Plants were slow to absorb all these gases, which would not prevent global warming from happening.

Answer:

The high sugar content caused too much water to move out of the root cells.

Explanation:

Too much causes transpiration to occur, in this case too much water killed the plant.

The statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

High sugar content in plants may be defined as the amount of carbohydrates (glucose) and their components get accumulated in the different parts of the plants in a high ratio. It also affects the rate of photosynthesis.

High sugar content leads to the loss of water (transpiration) in plants. In this condition, water loss is maximum which results in the scarcity of water in the root cells. And hence the plant died.

Therefore, the statement which explains why the plant in Group E and F died is that the high sugar content caused too much water to move out of the root cells.

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.
