Answer:
The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs.
mitosis is the only type of cellular division in which:
Answer:
itosis is a process where a single cell divides into two identical daughter cells.
Explanation:
Mitosis is the only type of cellular division in which number of chromosomes is maintained
What is mitosis?During the phase of the cell cycle known as mitosis, duplicated chromosomes are physically split in half to form 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.
Mitosis serves a very vital purpose in living creatures, and one of its functions is the regeneration and replacement of worn-out and damaged tissues. Mitosis contributes to the generation of identical copies of cells and, as a result, assists in the process of healing damaged tissue or replacing cells that have been worn out.

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.

What molecules diffuse through the cell membrane without the use of energy and are required as reactants in photosynthesis?
A.glucose and oxygen
B.water and oxygen
C.glucose and carbon dioxide
D.water and carbon dioxide
Answer:
c
Explanation:
If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport. Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O 2) and carbon dioxide (CO 2)

Describe an approach for understanding global systems and the changes they undergo
IN UR OWN WORDS
ill give brainliest if its in ur own words
50 points :)
Answer
To understand the global systems and the changes they undergo in a better way, we can use a model to represent the various ecological processes that occur within the biosphere. One example of a model that we can use is the earth systems model. It can show the causes and effects of global change to provide us with insights and learning about the global system as a whole.
Explanation:
Answer:
To be able to understand global systems and their changes first we must survey them before and relook at the systems and analyze how they have changed and what caused these changes.

e. You are at the line, waiting for you race to start, and your heart begins to pound.
A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.
The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.
The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).
The Somatic Nervous System is responsible for controlling the voluntary movements of the body.
The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.

what is the difference in solubility of triglyceride and the products of their hydrolysis
Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.
Explanation:
Hope this helps.
The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.
Why are triglycerides insoluble?Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.
This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.
Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.
Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.
Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.
