What is Cytosine? Where is it located in the DNA? Who is it paired with? What is the role of Cytosine?
Answer:
cytosine is one of the three pyrimidine nucleobases used in forming nucleotides of the nucleic acid
It is located opposite guanine in the DNA double helix
It pairs with guanine in both DNA and RNA forming three hydrogen bonds
cytosine is one of the nitrogenous bases coding the genetic information molecules carry
It can even be modified into different bases to carry epigenetic information

You give one plant fertilizer and compare how tall it grows to a plant that has not been fertilized.
What is the manipulated variable and the responding variable?
Answer:
Where I am it's called the Independent variable (Manipulated), but anyway, the manipulated variable is whether the plant has fertilizer or not, and the responding variable is the height growth of the plants.
Explanation:

Compare and contrast meiosis and mitosis. How many daughter cells are produced by each, and how many chromosomes do they have? In what contexts do meiosis and mitosis occur?
Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.
Explanation:
Answer:
see explanation
Explanation:
Meiosis is involved in gamete reproduction and results in four genetically distinct daughter cells. In contrast, mitosis involves the somatic cell and results in two genetically identical daughter cells. In mitosis when the division is complete you have two diploid cells. A diploid cell has two sets of chromosomes. Whereas with meiosis whose goal is to produce gametes you end up with 4 haploid cells. A haploid cell has just a single set of chromosomes. Meiosis and mitosis go through very similar phases however meiosis crossing over takes place and variation occur. Mitosis the division takes place in four stages and in Meiosis there is a two-division process of four stages each.

Which photosynthetic process can occur without light?
A. NADPH formation
B. The reaction at photosystem |
C. ATP formation
D. The Calvin cycle
SUBMIT
Answer:
D
Explanation:
ATP formatioon is not a photosyntheic process, neither is NADPH formation. The calvin cycle is correct because it can happen with or without light

the function of ribosomes is to synthesise _______
please help meant to fill in the blank bit
Answer:
the nucleolus
Explanation:
In the eukaryotic cell, the subunits that make up ribosomes are synthesized in the nucleolus. Once formed, these subunits pass through nuclear pores and are functional only in the cytoplasm when the two subunits are attached to an RNA molecule. Ribosomes are machines for translation.

What processes maintain a steady state “resting” membrane potential
Answer: Sodium-Potassium pumps (NaK Pumps)
Explanation:
So you only need to consider two things:
Are these ions mainly found on the inside or outside of the cell?
What are the ions' charges?
The location of the ions: Sodium is mostly found outside of the cell.
Potassium is mostly found inside of cells.
Sodium and potassium both have a positive charge.
So, consider this: what does sodium want to do? It wants to RUSH INTO the cell for two reasons: there is more on the outside, and the inside of the cell is negatively charged, which attracts it.
Potassium wishes to do the direct opposite. It is mostly inside the cell and wants to get out. Also, because opposite charges repel each other, potassium wishes to leave the cell.
Okay, so sodium enters the cell and potassium exits. What is it that keeps them where they are?
The sodium-potassium pumps. They take out sodium to keep it outside the cell and bring potassium back in. This is what it means to "maintain a steady state resting membrane potential."
It's three sodium ions leaving and two potassium ions entering per "pump."
HELP ME ASAP PLEASE.
How does water move from leaves to root? explain
Answer:
During transpiration, water will evaporate from tiny holes in the surfaces of leaves into the air (the tiny holes are called stomata). As the water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

What is the significance in regenerating NAD+ in fermentation??
Answer: The recycling of. NAD+ allows glycolysis to continue. The products of this process are two molecules of an alcohol, often ethyl alcohol, two molecules of carbon dioxide, and two molecules of NAD+. Just like lactic acid fermentation, alcoholic fermentation recycles NAD+ and so allows glycolysis to keep making ATP.
