Answer:
The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.

A very important by-product of the Calvin cycle is...
A. Oxygen
B.Carbon dioxide
C. Water
Answer:
B.Carbon dioxide
Explanation:
The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+. (ADP and NADP+ are not really "products." They are regenerated and later used again in the Light-dependent reactions). Each G3P molecule is composed of 3 carbons.
Which greenhouse gas is generated by 95% human activity
and 5% due to natural processes?
Answer:

Explanation:
Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2018, CO2 accounted for about 81.3 percent of all U.S. greenhouse gas emissions from human activities.
Answer:
carbon dioxide co2

Why would combining cells that result from Mitosis not work for fertilization?
Pls pls answer I need help!
Answer:
Because cells that result from mitosis are diploid i.e. contain two sets of chromosomes.
Explanation:
Mitosis is a type of cell division that produces daughter cells that are genetically identical to the parent cell. The chromosomal number of cells formed from mitosis remains the same as the parent cell. This means that if a parent is diploid (2n), the daughter cells from mitotic division will be diploid (2n).
However, for fertilization during sexual reproduction to occur, two haploid or half of the chromosome number of the parental organism must unite to form a whole diploid organism. In other words, two haploid cells (n + n) must come together in fertilization to give a diploid cell (2n). Hence, combining cells that result from mitosis would not work for fertilization because cells that result from mitosis are already diploid i.e. contain two sets of chromosomes.
1. Which layer of the atmosphere has:

Answer:
question 1- a. troposphere b. mesosphere
question 2- Earth's atmosphere is similar to a jacket for our planet. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens.
question 3- temperature because Scientists divide Earth's atmosphere into four main layers classified according to changes in temperature.

Construct a food chain. Place the organism in order from producer, primary consumer to secondary consumer to tertiary consumer. (An owl eats a snake, the snake eats a squirrel, the squirrel ate a nut.)
Answer:
nut is the producer the squirell the primary cosumer a snake is the secondary consumer the owl is a terriary consumer
In the given scenario, nut is producer, squirrel is primary consumer, snake is secondary consumer and owl is tertiary consumer.
What is a food chain?The food chain depicts how living things obtain food. Some animals only eat plants, while others eat other animals. The food chain is made up of four types of organisms: producers, consumers, prey, and predators.
Food chains are significant because they reveal the intricate relationships that exist in ecosystems.
They can reveal how each organism is dependent on another for survival. Food chains also show what happens when there is a problem and a producer or consumer is lost. Entire communities can be destroyed.
The nut is the producer, the squirrel is the primary consumer, the snake is the secondary consumer, and the owl is the tertiary consumer as per the given situation.
Thus, the food chain here is nut--->squirrel--->snake--->owl.

The diagram shows a Punnett square made to predict the earlobe shape of the offspring of two parents. The capital A stands for the trait of free-hanging earlobes, and the lowercase a stands for the trait of attached earlobes. Write the genotype of each offspring. What will be the phenotype of each offspring? Is the trait of free-hanging earlobes dominant or recessive? What is the expected ratio of free-hanging earlobes to attached earlobes in the offspring? \
Answer:
AA
free-hanging earlobes
Aa
free-hanging earlobes
Aa
free-hanging earlobes
aa
attached earlobes
Explanation:
The expected ratio of free-hanging earlobes to attached earlobes in the offspring of two heterozygous parents (Aa x Aa) is 3:1. This means that for every four offspring, three will have free-hanging earlobes, and one will have attached earlobes.
What is a punnett square?A Punnett square is a diagram used to predict the probability of offspring inheriting certain traits based on the genotypes of their parents. It consists of a grid with the possible gametes (sperm or egg cells) of each parent along the top and left sides.
The possible genotypes of the offspring are then filled in by combining the gametes in each box of the grid. The resulting genotypes can then be used to determine the probability of each phenotype (physical trait) appearing in the offspring. Punnett squares are commonly used in genetics to study the inheritance patterns of traits such as eye color or blood type.

the concentration of solute outside of the cell are_____than the inside of the cell
What happens to a cell in a hypertonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Explain how mRNA is formed from the DNA template.
Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Sarah is finishing a model drawing of a cell. She adds a membrane to the nucleus on her model. The nucleus of a cell has a membrane that isolates
material inside of it from the rest of the cell. Why does the nucleus need a membrane?

The membrane helps the nucleus to create energy for the cell.
B.
The membrane helps the nucleus to create proteins for the cell.
C.
The membranes helps the nucleus to remove waste from the cell.
D.
The membrane helps the nucleus protect genetic material for the cell.
Answer:
C
Explanation:
a nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials such as nucleic acids and proteins, between the nucleus and the cytoplasm .
