Describe the relationship between blood, tissue, fluid and lymph
Answer:
Nutrients such as glucose and amino acids as well as oxygen are pushed out from the blood into the tissue fluid. The rest of the fluid is collected by the lymphatic system. The lymph is similar to the tissue fluid. This is the relationship between tissue fluid and lymph.

PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.

Give two examples of what a living thing can do once it has converted the energy from food into usable forms of energy.
Answer:
When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.
The chemical energy, which is needed by the organisms comes from the food. Food comprises organic molecules, which captivates energy in their chemical bonds.
• The organisms generally use two kinds of molecules for chemical energy, ATP and glucose.
• Both the molecules are utilized as fuels all through the living world.
• Energy is the tendency to perform an activity. It is required by all the living species and every living cell to perform the processes of life.
• Energy in the form of chemical energy is utilized to dissociate and form the molecules, and to transport several molecules through the cell membranes.
• The organisms primarily use ATP and glucose for energy.
Thus, the form of energy required by the living species to perform the essential activities of life is obtained from food.

What will happen if external factors affect cell division in a group of cells placed in a culture dish
Answer:
The effect of an external physical factor on cell division is clearly seen in density-dependent inhibition, a phenomenon in which crowded cells stop dividing. ... When cells have formed a complete single layer, they stop dividing (density-dependent inhibition).

A scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. What did the scientist most likely learn from the observation? a The reaction caused an output of energy. b The reaction produced water. c The reaction consumed water. d The reaction required an input of energy.
Answer:
a The reaction caused an output of energy
Explanation:
Adenosine triphosphate, commonly known as ADP, is an high-energy storage molecule in living cells. It stores and transfers needed energy for metabolic activities. ATP stores its energy in the bonds that hold the phosphate group in its structure. However, the energy is released for use during metabolic processes when the phosphate bond is broken, leading to the release of ADP molecule.
In this case, a scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. This means that the reaction has caused ATP molecules to release its stored energy i.e. an energy output.

What is Electron Transport Chain and what happens in that stage of cellular respiration?
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.

Which structure is correctly paired with its function? (1) testis — produces nutrients for the offspring (2) placenta — allows nutrients to diffuse from the mother to the embryo (3) uterus — produces testosterone used in egg production (4) ovary — provides a place for the internal development of the embryo
Answer:
(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.
what gives sperms motility
Answer:
The tail of the sperm, the flagellum
Explanation:
We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.
Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.
Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.
