The difference between solstice and equinox is:
A. During the equinox the solar energy falls on the equator allowing all of Earth to receive equal amount of energy and during the solstice the solar energy falls on the tropics allowing them to receive the largest amount of energy.
B. During the equinox the Earth receives the largest amount of energy in the north pole and not during the solstice.
C. During the solstice the solar energy falls on the equator making all of Earth to receive equal amount of energy and during the equinox the solar energy falls on the tropics making them receive the largest amount of energy.
D. There is no difference they mean the same thing.
Answers
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.

Answers
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate
Explanation:
Enzymes usually have a very specific structure than holds the substrate molecules, facilitating the optimal environment for the reaction to proceed. This reduces the activation energy required to start the reaction.
If the shape changes, the substrate molecule will no longer properly fit. Therefore, the enzyme will not be able to catalyze the reaction.
how does radiant energy become food for a plant?

1) Briefly describe the process of DNA replication.
a) Start with the molecular machinery and be sure to describe what DNA polymerase does. Use the terms ‘free nucleotides’, ‘helicase’, ‘polymerase’, ‘complementary’.
b) describe the result; how many strands were made? Describe their composition. Use the terms ‘parental DNA’ and ‘new DNA’.
Answers
Answer:
The biological process that involves produces two exact copies of DNA from a DNA molecule is called DNA replication.
In this process, the enzyme helicase unzips the DNA double helix by breaking the hydrogen bonds that bind bases together in the structure. Unzipping the hydrogen creates a replication fork. Every strand of the DNA acts as a template but oppositely oriented known as the leading strand in 3’ to 5’ direction and the lagging strand in the 5’ to 3’ direction.
One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the leading strand. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the lagging strand. As a result of their different orientations, the two strands are replicated differently.
Primer acts as an initiating site for DNA synthesis and DNA polymerase enzyme adds new complementary nucleotide base by attached and moving on the leading strand in the direction of 5' to 3' which is reversed to the strand.
After the binding and synthesis of all the bases, the enzyme called exonuclease removes the primer from the strand. One new and an old chain of two DNA molecules are synthesized by DNA replication due to the one new and one parent molecule in DNA it is known as semi-conservative.

Answers
Answer:
Tissue
Explanation:
The spleen and the thymus work together to fight infection. These organs together make up immune system.
What is immune system?The immune system defends the organism's body against external invaders. Toxins and germs such as bacteria, viruses, and fungi are examples of these (chemicals made by microbes).
The immune system is made up of various organs, cells, and proteins that collaborate.
The thymus and bone marrow, lymph nodes and vessels, spleen, and skin are all vital to the immune system's proper functioning.
The spleen filters and stores blood, as well as producing white blood cells to fight infection or disease.
The thymus gland is located in the upper chest, beneath the breast bone. It is responsible for the maturation of a specific type of white blood cell that fights off foreign organisms.
Thus, immune system encompasses spleen and thymus.

B Cells contain DNA, which controls the production of proteins.
C Proteins combine to produce cells, which produce DNA.
D DNA is made up of proteins, which tell a cell how to function.
Answers
Answer: cells contain DNA, which controls the production of proteins
Explanation:
The statement best describes the relationship that exists among proteins, DNA, and cells - B. Cells contain DNA, which controls the production of proteins.
A cell contains DNA that produces proteins
A cell has many substances and organelles present in it, that all have specific functions in the cell. DNA is the hereditary unit of the cell that contains genetic information about growth, development, and reproduction.
DNA helps in synthesizing protein by a two-step process called protein synthesis. The first step called transcription involves copying the instruction from DNA into an mRNA sequence and the second is producing an aminoacid chain by translating the mRNA sequence.

Tobias found a rock that has a mass of 475kg. He placed it in 2000ml of water and the water rose to 2025ml. What is it’s density?
Answers
Given parameters:
Mass of rock Tobias found = 475kg
Volume of initial water = 2000mL
New volume = 2025mL
Unknown:
Density = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL
Now let us convert the mass to g;
1000g = 1kg
So; 475kg will be 475000g
So;
Density of stone = [tex]\frac{475000}{25}[/tex] = 19000g/mL or 19000g/cm³
