1. MAINIDEA Describe how cyclins control the cell cycle.
is
Explanation:
They drive the events of the cell cycle by partnering with a family of enzymes called the cyclin dependent kinases (cdk). A cdk is inactive, the binding of a cyclin activates it, making a funcyional enzyme.

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
exit the cell? Explain in terms of the composition of the plasma membrane. In your own words, explain the fluid mosaic model proposed by Singer and Nicholson.
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 resulting product of cellular respiration?
Answer:
Carbon dioxide, ATP and water.
_____ - is the study of how things work; gathering new information, new investigations.
Q: What's the answer?
Answer:
science
Explanation:
why does your body release a little bit of energy with each step rather than all at once?
In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.
How glucose used in cellular respiration?During the process of aerobic cellular respiration, glucose reacts with the oxygen which leads to form ATP ( Adenosine triphosphate) that has to be used by the cell. Carbon dioxide and water has been created as the byproducts. The overall equation for the process of aerobic cellular respiration is that during cellular respiration, glucose and oxygen react in order to form ATP ( Adenosine triphosphate).
Adenosine triphosphate has known as an organic compound which provide energy to living organisms to drive many operations in living cells such as contraction of molecule, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
The energy consumed by the animals in the form of glucose has been conserved because it is transformed into the chemical energy as the carbon dioxide has been produced during the respiration.
Therefore, In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.

why is it necessary for plants to have chloroplasts
Answer: In some organisms, chloroplasts play a vital role in the photosynthesis process. The chloroplast receives sunlight's energy and converts it to sugars. In some organisms, chloroplasts play a vital role in the photosynthesis process.

How do human activities affect the carbon cycle?
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).

what is the first structure to emerge from a germinating seed
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.

a hormone that can lower blood levels of calcium ion is
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]

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.
