Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.
Homologous pairs separate in meiosis _________, and sister chromatids separate in meiosis _________.
Answer:
Meiosis I
Meiosis II
Explanation:
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II.
In meiosis II, these chromosomes are further separated into sister chromatids.
Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
4) Why are these chromosomes in pairs? From where do they come?
Answer:
Chromosomes are long strands of DNA mixed with proteins. They come in pairs, one male (from the father) and one female (from the mother).

why you add water to Sulphur dioxide and put a blue Litmus Paper in it why does it turns red
Answer:
Because it produce weak acid and acid turns blue lithmus paper to red.
Explanation:
Sulphur dioxide SO2 react to added water to produce acidic product.
When sulphur dioxide react with water, it produce sulphurous acid H2SO3 which is a weak acid.
One of the properties of acid is that they turn blue lithmus papper to red, because the product is an acid, blue lithmus papper turns to red.

Most carbohydrates in the human body are-
A. used as building blocks for proteins
B. used as catalysts for reactions in cells
C. consumed as a source of energy
D. not easily absorbed into the bloodstream
Answer:
C/D
Explanation:
Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
(SUMMARIZED ANSWER: One of the primary functions of carbohydrates is to provide your body with energy. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream)

What makes life on the Earth possible?
Answer:
The balance between the biosphere, geosphere, hydrosphere, and atmosphere make life on Earth possible. Each component of the Earth system interacts with the others to exchange matter and make life possible.
Thats the answer
Explanation:
The factors which makes life on Earth possible are: energy, carbon, water in liquid form, and various other elements such as nitrogen, phosphorus, hydrogen, and most important oxygen.
What are the conditions on Earth?
Earth has a gaseous atmosphere which is responsible for making life possible on the planet. It is the third planet from the Sun. The atmosphere on Earth contains water vapor which helps to moderate our daily temperatures on the planet. The atmosphere contains 21% oxygen, which is necessary for breathing of organisms, and 78% nitrogen.
Earth is present at the right distance from the Sun, which keeps it protected from the harmful solar radiations coming from the sun by the magnetic field, keeps it warm by an insulating the atmosphere, and also has the right chemical ingredients for life, including water and carbon.

What term best describes region “B” of the phospholipid model above?
Answer:
Hydrophobic
Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.
The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.
What is phospholipid model ?
Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.
The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.
Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.
Hence the region marked as B is saturated and unsaturated fatty acids.
