Answers

Cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.

Cells need a constant supply of energy to preserve the biological order that keeps them alive, this energy comes from chemical bonds in food molecules, which are fuel for cells.

Cellular respiration is one of the most important processes that occur within living cells, it is constituted by a series of oxide reduction reactions, which allow obtaining energy through the degradation of an organic substance, glucose.

The cells that make up the body take advantage of the energy of chemical bonds, contained in glucose, when the molecule is degraded and oxidized to carbon dioxide (CO2) and H2O.

This energy is stored in the form of high-energy bonds (covalent bonds that release large amounts of energy when hydrolyzed) in ATP and NADPH molecules.

In turn, these carrier molecules are like portable sources of the chemical groups and electrons necessary for biosynthesis.

Therefore, we can conclude that cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.

Explanation:

Tyrone and Valerie wanted to determine what feature of a paper airplane would cause it to fly the farthest. Tyrone made his airplane with wider wings than Valerie's airplane. Valerie's airplane had shorter wings than Tyrone's. After testing the two airplanes several times, the data shows that wider wings help airplanes fly farther than shorter wings.

Which characteristic of science is missing from this experiment?

The question is not testable because paper airplanes are always changing.
The phenomenon is not observable because air resistance changes.
The experiment is not replicable because controlled variables are not included.
The results are not reliable because the airplanes were only tested one time.

Answers

Answer: Calcitonin

Explanation:

When calcium levels in the blood is low, Parathyroid hormone is released to increase it. On the other hand, when calcium levels are high and need to be decreased, Calcitonin is secreted.

Calcitonin acts in opposition to PTH by inhibiting osteoclasts (a cell from which bone develops), stimulating osteoblasts, and increasing the excretion of calcium into the urine by the kidneys. [lumencandela]

How do human activities affect the carbon cycle?

Answers

Answer

The main human activities responsible for it are:-

1) Fuel combustion, deforestation and industrial production (especially cement factories)

2) Increase in population (humans emit nearly 32 gigabytes of carbon dioxide each year).

3) Imbalance in the carbon dioxide cycle (the ocean does not absorb all of the carbon dioxide, and vegetables cannot convert all of the carbon dioxide into oxygen).

in eukaryotes dna and proteins combine to form

In eukaryotes,DNA and proteins combine to form chromatin.

Explanation:

DNA is normally tightly packed into the nucleus of a eukaryotic cell, through protein-DNA complexes that form the characteristic condensed 'chromosome' shape.

The phospholipid bilayer is composed of fats with Hydrophobic core. If protein channels were absent in the cell membrane, would water soluble nutrients be able to enter or

Answers

Without the nuclear membrane the cell would collapse and die. Without the cell membrane, any chemical would be allowed to enter. Membranes are very important because they help protect the cell. Materials move across the membrane by diffusion.

what is the first structure to emerge from a germinating seed

Answers

Answer:

The radicle is the first structure to emerge

The root apical meristem produces a root cap to protect the radicle, which emerges first from the seed to improve water uptake.

What is germination?

Germination is the process through which a seed, spore, or other reproductive body typically breaks dormancy and begins the process of sprouting.

The embryo absorbs water and expands cells during seed germination. After water intake, or imbibition, respiration increases and metabolic functions, paused or greatly decreased during dormancy, resume. These processes are linked to structural changes in embryo cell organelles (metabolic membranes).

The radicle, which is the primary embryonic root, emerges from the seed first in order to maximize the plant's capacity to absorb water. The root cap, which is produced by the root apical meristem, serves to shield the radicle.
