Answer:
A) Hydrogen Atoms
Explanation: Water provides hydrogen (H) and (O) atoms for making biological molecules.
Water is a source of both (a) and (b) for chemical reactions in cells. Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side which participate in chemical reaction.
what are the features of water molecule ?
Water is tasteless, odorless, or transparent, where oxygen atom having nucleus attracts electrons more strongly than the nuclei of the hydrogen atoms.
So oxygen is more electro negative and electron-greedy than hydrogen atom, resulting in the development of a partial negative charge on the oxygen atom of the water and a partial positive charge on the hydrogen end.
Water shows both cohesive and adhesive properties where adhesion of water molecules refers to stick to some other substance while cohesion is the property of water molecules to stick together.

Which two types of glia are both glue-like?
Options:
A. Schwann cells and oligodendrocytes
B. microglia and astrocytes
C. ependymal cells and microglia
D. interneurons and astrocytes
Answer:
B
Explanation:
Microglia and astrocytes are both glue-like.
What are the functions of astrocytes?
Astrocytes are specialized glial cells that outnumber neurons by over fivefold. They contiguously tile the entire central nervous system (CNS) and exert many essential complex functions in the healthy CNS.
Astrocytes not only regulate blood flow, but also transfer mitochondria to neurons, and supply the building blocks of neurotransmitters, which fuel neuronal metabolism.
Astrocytes are capable of producing a robust antioxidant response to protect themselves and also neurons, through the release of glutathione precursors to neurons.

How does the energy the reactants and products differ between an energy-absorbing reaction and an energy-releasing reaction?
Explanation:
Endothermic reactionIn an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.
in eukaryotes, one distinct feature of chromosome organization that is different from prokaryotes is __________.
Prokaryotes are creatures made up of cells without cell nuclei or any membrane-enclosed organelles.
What difference in organelle in eukaryotes and prokaryotes?
Eukaryotic cells, which are defined as cells with organelles that are membrane-bound, are the building blocks of both unicellular and multicellular organisms.
Prokaryotic cells, in contrast, are invariably seen in unicellular organisms and lack any membrane-bound organelles.
Eukaryotes are organisms made up of cells that have membrane-bound organelles and a nucleus that houses genetic material.
Therefore, in eukaryotes, one distinct feature of chromosome organization that is different from prokaryotes is nucleus.

which cells of the juxtaglomerular apparatus secrete renin?
Answer:
smooth muscle cells,
Explanation:
The granular cells of the juxtaglomerular apparatus secrete renin. Thus, the correct option is B.
What are Granular cells?The granular cells are present on the arteriolar walls. These are the main renin-producing cells of the kidney. These cells have a rough endoplasmic reticulum, a well-developed Golgi apparatus, and numerous cytoplasmic granules, and they also have the fine structure of protein-secreting cells with them.
The renin-containing granules in the granular cells are generally membrane-bound. Some granules are believed to be the more newly formed with a crystalline lattice appearance and may mainly contain the pro-renin molecule while, others with an amorphous electron-dense content, are believed to be representing the mature form.
Therefore, the correct option is B.

A. increasing
B. marginalizing
C. decreasing
D. neutralizing
Explanation:
What I got to have
Eutrophication (from Greek eutrophos, "well-nourished") is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients. It has also been defined as a "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication in freshwater ecosystems is almost always caused by excess phosphorus.

Genetic code
mRNA
Mutation
Answer:
The genetic code is the code our body uses to convert the instructions contained in our DNA the essential materials of life. It is typically discussed using the “codons” found in mRNA, as mRNA is the messenger that carries information from the DNA to the site of protein synthesis.
Everything in our cells is ultimately built based on the genetic code. Our hereditary information – that is, the information that’s passed down from parent to child – is stored in the form of DNA. That DNA is then used to build RNA, proteins, and ultimately cells, tissues, and organs.
Like binary code, DNA uses a chemical language with just a few letters to store information in a very efficient manner. While binary uses only ones and zeroes, DNA has four letters – the four nucleotides Adenine, Cytosine, Guanine, and Thymine/Uracil.
Thymine and Uracil are very similar to each other, except that “Thymine” is slightly more stable and is used in DNA. Uracil is used in RNA, and has all the same properties of Thymine except that it is slightly more prone to mutate.
This doesn’t matter in RNA, since new RNA copies can be produced from DNA at any time, and most RNA molecules are intentionally destroyed by the cell a short time after they’re produced so that the cell does not waste resources producing unneeded proteins from old RNA molecules.
Together, these four letters of A, C, G, and T/U are used to “spell” coded instructions for each amino acid, as well as other instructions like “start transcription” and “stop transcription.”
Instructions for “start,” “stop,” or for a given amino acid are “read” by the cell in three-letter blocks called “codons.” When we talk about “codons,” we usually mean codons in mRNA – the “messenger RNA” that is made by copying the information in DNA.
For that reason, we talk about codons made of RNA, which uses Uracil, instead of the original DNA code which uses Thymine.
Each amino acid is represented in our genetic instructions by one or more codons, as seen below.
Codon table
One of the most remarkable evidences for the common descent of all life on Earth from a single ancestor is the fact that all organisms use the same genetic code to translate DNA into amino acids.
There are a few slight exceptions to be found, but the genetic code is similar enough across organisms that when a gene from a plant or jellyfish is injected into a mammal cell, for example, the mammal cell will read the gene in the same way and build the same product as the original plant or jellyfish!
