If convection cells in the asthenosphere are the mechanism behind plate tectonic movement, what powers the convection cells?
a) energy from the sun
b) energy from the earth's core
c) air pressure changes
d) energy from magma
Answers
The energy that powers the convection cells is ENERGY from the earth's core (Option B).
Convection currents, also known as convection cells, are caused by density differences within a body of liquid or gas. Convection cells inside of the Earth form as material near the Earth's core heats up.The asthenosphere refers to the upper mantle layer beneath the lithospheric mantle which is involved in plate tectonic movement.The heat inside the Earth's core heats the asthenosphere, which is associated with the movement or 'motion' of convection cells.In conclusion, the energy that powers the convection cells is ENERGY from the earth's core (Option B is correct).

What is protein?
Protein has been defined as the large macromolecules as well as biomolecules that are used to made up of the long chains of the amino acid. There has been various function of the protein such as the DNA replication, speeding up of chemical reaction which helps to maintain the structure of cell.
The main function of the protein has to maintain the structure and function of the organs, repair muscle, and the muscles. Diet contains high protein has been recommended for the purpose of losing weight, reducing fat, or increasing fat.

Herbivore
Explanation:
The grasshopper eats grass and does not seem to eat anything else in the food web, so it is a herbivore. Herbivores are organisms that eat plants, and since the grasshopper furfills this definition, therefore it is a herbivore. It is not a carnivore because carnivores do not eat grass. It is not a decomposer because it does not break down dead material. It is not an omnivore because it does not eat both plants and animals.
What is a hypertonic, hypotonic, and isotonic solution?
Answers
Answer:
Explanation:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, the relative concentrations of solute and water are equal on both sides of the membrane. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
This stadium can hold 100,000, or 1x10, people. The
number of atoms in a grain of iron is about 1x 1016,
Would you need 1 x 10° or 1 x 10' stadiums to hold
the same number of people as the number of atoms in
a grain of iron? Explain your answer,
Answers
Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

Answer:
The correct answer is - Option A and option D.
Explanation:
Mitochondria and chloroplast both have their own DNA as the prokaryotic cells like bacteria. The DNA found in these organelles are circular formation like DNA in prokaryotes.
They contain their own ribosomes that are a small organelle that helps in the production of protein. The ribosomes found inside chloroplasts and mitochondria similar in size that present in prokaryotic cells.

How is cold front formation different from stationary front formation? Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses. Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold air mass moves over a warm air mass. Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when a warm air mass moves over a cold air mass.

Small population is the answer

According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.
What is the theory of natural selection?Natural selection is the procedure via which populations of living organisms acclimate and modify.
Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.
Natural selection leads to evolution.
Thus, genetic diversity best allow a species to survive environmental changes.

If an organism is multicellular, it probably has
A.) Prokaryotic cells
B.) Eukaryotic cells
C.) Cancer cells
D.) All of the above
Answers
Answer:
B. Eukaryotic cells
Explanation:
Prokaryotic cells are only seen in unicellular organisms as bacteria and cancer cells are just cells where there has been an error in division or a mutation.
If an organism is multicellular, it probably has - option B.) Eukaryotic cells.
Cells are of mainly two types prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that:
Eukaryotic cells have a nucleus in which genetic material is stored enclosed by a nuclear membrane.All prokaryotic cells only form single-celled (unicellular) organisms without a true nucleus or membrane-bound structures, examples of prokaryotes are bacteria and archaea. Organisms with eukaryotic cells are called eukaryotes that can be either multicellular such as animals, plants, fungi, and protists, or single-celled as well. So, all multicellular organisms are eukaryotes..Thus, If an organism is multicellular, it probably has - option B.) Eukaryotic cells.

Define 3 of the major parts of the skeletal system and list the

Answers
Answer:
Bone
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
Ligament
Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.
Tendon
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Cartilage
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

Why only certain cell undergo mitosis
and why other cells undergo meiosis
Answers
Explanation:
Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. Single-celled eukaryotes, such as amoeba and yeast, use mitosis to reproduce asexuallyand increase their population. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
