The first electrons to be excited by light energy are found in

Answers

Answer 1

Answer:

The first electrons to be excited by light energy are found in Photosystem II (PSII). It is a specialized protein complex that captures the energy from sunlight and uses it to extract electrons from water molecules.Light is absorbed by chlorophyll, carotenoid and phycobilin pigments in the antenna regions. The excitation energy is rapidly transferred to the reaction centre domain.

Answer 2

Answer: Photosystem II is the correct answer

According to theories concerning the origin of life, the atom shown is a likely choice for the basic element of all livings things because?

Answers

Atom is the basic element of all living things because it's small. It is the smallest constituent unit of matter which has the properties of a chemical element. They are very small. Sizes are about 100 or 100, 000 fm. They are unstable. They are composed of a nucleus and electrons.

Explain what has to happen to join two monosaccharide units into a disaccharide.

Answers

Dehydration synthesis is the process by which two monosaccharide are joined to form a disaccharide.

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

What is gaseous exchange

Answers

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs from the lungs between the alveoli and a network and a bunch of tiny blood vessels called capillaries, which is located in the walls of the alveoli.

~Sorry if I typed some stuff wrong, I'm eating a popsicle while typing this~

Answer:

Gas exchange is the diffusion of gases in and out of the body

Explanation:

The percentage of crossing-over between 4 linked genes (K, L, M, N) are below. Put them in the correct sequence.Between M and N: 8%

Between K and N: 5%

Between K and L: 16 %

Between N and L: 11%

Between M and L: 19%

Answers

Answer:

NL=8, JK=2, KL=2, LM=2

Explanation:

K is between J and M

JM=JK+KM

JM=KL+KM

JM=2+4

JM=6

The length of JM is 6 units.

From the figure it is clear that

MN=JN-JM

MN=14-6

MN=8

From the figure it is clear that

NL=ML+MN

NL=2+8

NL=10

Frozen water has less density than liquid water. How does this property of water affect life on earth?

Answers

I think that Ice is denser than water to regulates the life of an organism living in the ice that would capable of them in living there. There are called Thermophiles that lives in by the sulfuric vents at the bottom of the oceans and if ice would be at the bottom, they would survive their.

Answer:

Water has various properties as frozen ice is less dense as 0.9340 g/cm cube compared to density of water at room temperature is 997 kg/m cube.

Explanation:

The dissolving effect of water is fundamental to life from son earth and it's due to this property of water that makes it more mobile and more elastic. As wherever water goes it carries with it the dissolved salts, nutrients and other chemicals that support life.

If water is at room temperature it can be used with other substances as to from compounds and give the desired results upon reacting with the various elements. As most liquids contract when they are cooled to ice forms that we have seen in glaciers the ice caps and polar landmasses have life frozen in freshwaters.

Ice can carry along with it various types of gases and rare earth that can be remained preserved inside the earth for years. Even earth core consists of liquid water which is itself a sign that life on earth is a result of the changing forms of water sphere on earth.
