Its function is to provide energy for many cellular reactions.
<u>Human activity</u>. The sixth mass extinction of of organisms caused by human actions potentially could go as far back as the late Pleistocene era (over 12,000 years ago.)
Answer:
These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past.
Explanation:
Answer: adenosine triphosphate (ATP) - the high energy chemical compound with three phosphate groups that provides energy for all other cell activities
endocytosis - when cells engulf or ingest substances
cellular respiration - chemical reactions in plants and animals that break down food molecules into energy (ATP)
movement of particles or molecules from higher concentration to lower concentration - diffusion
when cells expel or get rid of substances from within- exocytosis
a solution that has a higher salt concentration than the salt - hypertonic
the relatively constant state in the internal environment of an organism - homeostasis
Explanation:
Adenosine triphosphate or ATP is the energy currency that is required for providing energy for metabolic functions and activities in the body.
Endocytosis can be defined as the process through which a cell engulfs another cell or substances to get rid of them.
Cellular respiration can be defined as the process through which the food in the organisms is oxidized and broken into parts to release energy.
Diffusion involves the movement or transfer of gas, liquid, and solid particles from a region of higher to lower concentration without the requirement of semi-permeable membrane.
Exocytosis is a process in which the cell releases those substances that are required by the cell.
Hypertonic is a solution that has more solute concentration than solvent concentration.
Homeostasis is a tendency to maintain constancy in the internal environment of body in relation to changes occurring in the surrounding.
The difference is that mitosis produces two diploid (2n) somatic cells that are genetically identical, but meiosis produces four haploid (n) gametes that are genetically unique from each other.
