Which two biomes have moderate precipitation levels?A.Desert and tundra
B.Tropical rain forest and Taiga
C.Savanna and grassland
D.Grassland and desert

Answers

C. Savanna and grassland

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
A biome is composed of various diverging ecosystems that relates with the community. Biomes can either be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc.

What happens before mitosis occurs? A. The cell takes a rest./ B. Cytoplasm from the parent cell becomes two daughter cells./ C. The cell grows and makes a copy of its genetic material./ D. The genetic material of the parent cell multiplies into two sets.

Answers

Just before mitosis occur in a stage known as Interphase the cell grows and makes copies of its genetic material in preparation for the cell's division into two identical cells. Therefore, option (C) is correct.

What is mitosis?

In the study of cell biology, the phase of the cell cycle known as mitosis is the stage at which replicated chromosomes are partitioned into two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Conventionally, the process of mitosis is broken down into five stages that are referred to as prophase, prometaphase, metaphase, anaphase, and telophase.

although the digestive system is primarily responsible for the breakdown of food, this process can be disrupted if the circulatory system malfunctions. The best explanation for this disruption is that

Answers

Final answer:

The circulatory system plays a crucial role in carrying the nutrients absorbed by the digestive system to different parts of the body via the bloodstream. A malfunction in the circulatory system can interrupt the transportation of these nutrients, consequently disrupting the digestive process.

Explanation:

The digestive and circulatory systems are interconnected in the human body. Digestive process involves breaking down food into tiny particles that can be absorbed into the bloodstream. This occurs primarily in the small intestine, where most nutrients are absorbed from the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa.

However, when the circulatory system malfunctions, it disrupts the absorption of these nutrients. The circulatory system is responsible for distributing these nutrients to the different parts of the body. If it malfunctions, nutrient distribution is affected, thereby hampering overall bodily function including the digestive process.

For instance, the circulatory system plays a crucial role in carrying the absorbed nutrients from the small intestine to different parts of the body for use. This is done via the bloodstream. Therefore, a malfunction in the circulatory system can hinder this important process and subsequently disrupt the digestive system.

Adenosine Triphosphate Living organisms store chemical energy in the form of biomolecules. Organisms transform these biomolecules to other forms of energy when needed. For example, chemical energy is transformed into mechanical energy when a muscle uses energy to move. Adenosine triphosphate (ATP) is the most important biomolecule that provides chemical energy. ATP is like a storage unit of chemical energy for the cell. It’s the most abundant energy-carrying biomolecule in cells. The structure of ATP consists of a nucleotide made of an adenine base, a ribose sugar, and three phosphate groups. ATP releases energy when the second and third phosphate molecules are broken, forming adenosine diphosphate (ADP). ADP can also form adenosine monophosphate (AMP), but this reaction releases less energy than the reaction that converts ATP to ADP.

Answers

Answer:

Adenosine triphosphate (ATP) is an essential biomolecule that stores and provides chemical energy in living organisms. It acts as a "currency" for energy transfer within cells. Let's break down its structure and function:

1. Structure: ATP is composed of three main components:

a. Adenine base: It's a nitrogen-containing molecule that serves as a building block of nucleotides.

b. Ribose sugar: This is a five-carbon sugar molecule that is bonded to the adenine base.

c. Phosphate groups: ATP has three phosphate groups attached to the ribose sugar.

2. Energy Storage: The energy in ATP is stored in the bonds between the phosphate groups. These bonds are high-energy bonds, meaning they contain a lot of potential energy.

3. Energy Release: When the cell needs energy, ATP can be hydrolyzed, or broken down, by removing one phosphate group. This results in the formation of adenosine diphosphate (ADP) and an inorganic phosphate molecule. The breaking of this bond releases energy that can be used by the cell for various processes.

4. Recycling ATP: ADP can be further hydrolyzed to form adenosine monophosphate (AMP) by removing another phosphate group, but this reaction releases less energy compared to the conversion of ATP to ADP. ATP can be regenerated by adding a phosphate group back to ADP through a process called phosphorylation. This recycling process allows ATP to continuously provide energy within the cell.

To summarize, ATP is a molecule that stores and provides chemical energy in cells. It consists of an adenine base, ribose sugar, and three phosphate groups. Energy is released when ATP is converted to ADP by breaking the bond between the second and third phosphate groups. ADP can be further converted to AMP, but with less energy release. Through phosphorylation, ADP can be converted back to ATP, ensuring a continuous supply of energy for cellular process
