Explanation:
what are the inputs and outputs of the reaction
Answer:
The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The cycle's output is an energy-rich sugar molecule. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH.
Explanation:
The light reactions, which occur during photosynthesis, have specific inputs and outputs. The inputs of the light reactions include light energy and water. The outputs of the light reactions are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and molecular oxygen.
Light energy is absorbed by the chlorophyll pigments in the thylakoid membranes, while water molecules serve as a source of electrons for the photosynthetic electron transport chain.
ATP is a high-energy molecule that serves as the primary energy source for cellular processes. NADPH is a coenzyme that carries energized electrons and plays a role in the synthesis of carbohydrates during the subsequent dark reactions of photosynthesis. Molecular oxygen is a byproduct of light reactions and is released into the atmosphere as a waste product. Together, these outputs provide the energy and reduce the power needed for the synthesis of organic molecules during photosynthesis.
Therefore, the inputs of the light reactions include light energy and water. The outputs of the light reactions are ATP (adenosine triphosphate), NADPH (nicotinamide adenine dinucleotide phosphate), and molecular oxygen.

Also, the corals provide much needed shelter for lots of marine animals, but also are on the menu of some, like the starfish for example.
Limestone is in form of sedimentary rock that is made up of skeletal fragments of marine organisms such as forams, corals and molluscs. However, limestone is formed from the shell of an organisms because the shell is made up of calcite or aragonite.
Due to the presence of nutrients that swipe from ocean to the shores along with tides which makes predators to be present along the shores which ultimately pose a threat to coastal aquatic organisms.

Decreased pH levels in lakes and rivers
Decreased concentration of aluminum in the soil
Changes in development of indicator organisms of an ecosystem
II only
III only
I and III
I and II
Answer:
I and III
Explanation:
Acid deposition will decrease pH levels in lakes and rivers since it contaminates them and lowers their pH, and organisms may be affected by the increased acidity in their immediate surroundings, but aluminum has nothing to do with pH levels at all.
Hope thish elped!
Option I and III shows the problems of environmental indicators of acid deposition.
The following information should be considered:
The acid deposition should reduce the level of pH in terms of lakes and rivers as it contaminates also the organisms should impact when the acidity should be increased for the surroundings. But the aluminum does not have any relationship with pH levels.Therefore we can conclude that options I and III are correct.

Answer:
They are typically smaller than eukaryotic cells. The DNA of a prokaryotic cell is contained in the nucleoid. There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

What is the electrical charge of the nucleus of an atom that has 11 protons , 12 neutrons , and 11 electrons ?
Answer:
The 11 positive protons cancel out the 11 negative electrons, and the overall charge of the atom is zero. So it neutral
Explanation:
I hope this helps!!
The nucleus of an atom has only protons and neutrons. Since the neutrons are neutral, the charge on the nucleus, in this case, would be +11.
What is the atomic charge?The difference between the number of electrons and protons in an atom is defined as the charge on that particular atom. An atom has three sub-atomic components. These are electrons, protons and neutrons.
The electrons are negatively charged, the protons are positively charged and the neutrons are neutral.
Because the neutrons are neutral, the increase or decrease in the number of electrons or protons affects the charge on an atom. If the number of protons is higher, the atom will be positively charged. If the number of electrons is higher, the atom will be negatively charged.
The protons and neutrons are present in the nucleus of an atom and the electrons are present in atomic shells.
Therefore, in a nucleus with 11 protons, and 12 neutrons, the charge will be +11

In a chemical analysis of a sample of animal tissue, which element would most likely be found in the smallest quantity?
Answer:
Iodine
Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.

All cells divide and reproduce the same way ... true or false explanation needed
Answer:
False
Explanation:
False because cells can reproduce in two ways. Mitosis, the process of making new body cells or cell division. OR Meiosis where there is genetic information transfered between cells such as how humans are made.
All cells do not divide and reproduce the same way since there are two methods for cells to divide. So, the given statement is False.
What is Cell division?The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle. Usually, cell division happens as part of a longer cell cycle where the DNA is reproduced as the cell nucleus divides during cell division.
Meiosis and mitosis are the two processes through which cells can reproduce. The process of creating new body cells, or mitosis, differs from meiosis, which is the process by which genetic material is passed between cells, as in the creation of humans. Thus, not all cells divide and reproduce in the same way.
