Answer:
D . The atomic number and atomic mass decrease from left to right across a period;
energy levels increase from top to bottom down a group.
Explanation:
On the periodic table, elements are arranged based on the periodic law. This law states that "the properties of elements are a periodic function of their atomic number".
The atomic number is the number of protons in an atom.
Atomic mass is the number of protons and neutrons in an atom
The energy level is the number of shells in an atom
As we move from left to right on the periodic table, both atomic mass and atomic number increases. Also, down a group, the energy level increases as the number period increases. From left to right, the energy level stays the same.briefly explain the relationship between cells, organs, and tissues
Answer:
In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.
Answer:
Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.
Explanation:
ATP (adenosine triphosphate) can be though of as a battery. It is also sometimes desribed as the energy currency of the cell. DNA and RNA are nucleic acids - the genetic information of the cell, and does not store and release energy. CMP is a nucleotide.
The energy found in ATP is found stored between phosphate groups of the molecule. When a phosphate group is released, it forms ADP (adenosine diphosphate)
Cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.
ATP is the energy coin of the cell whose hydrolysis is used to carry out many different metabolic functions (e.g., reproduction, differentiation, growth, etc).
ATP hydrolysis is a catabolic reaction, which provides releasable energy stored in the bonds between the second and third phosphate groups.
The molecule of ATP can transfer its energy to different molecules during many cellular processes such as, for example, DNA replication, active transport, muscle contraction, etc.
In conclusion, cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.

Explanation:
Which organisms release carbon dioxide as waste consumers only consumers ending D composers producers indie composers or producers only
Answer:
Producers and Decomposers
Explanation:
The organisms that release carbon dioxide as waste are consumers and decomposers. The correct option is B.
What are consumers and decomposers?Consumers are organisms that consume this food from plants like animals. And decomposers are organisms that convert complex food material into simple ones, like bacteria.
When an animal breathes out or exhales, waste carbon dioxide is released. Decomposers release carbon dioxide as they disintegrate dead plants and animals. Plants can use all the carbon dioxide produced in the atmosphere as a result of these activities.
Producers are only eaten by consumers before being broken down by decomposers. To restart the cycle, producers are fed with this dead material.
Therefore, the correct option is B. consumers and decomposers.

What does "enzymes are organic catalysts" mean?
Answer: Catalyst. Any molecule that will increase the rate of a chemical reaction, does not participate directly in the reaction and therefore is reusable, and does not supply the energy for the reaction (heat or ATP does). Enzymes work on one reactant, called a. Substrate.
Explanation:
Hope this helps.
Have a good night ma´am/sir.
Be safe!
"Enzymes are organic catalysts" refers to the fact that enzymes are an organic class of biological molecule that act as catalysts in chemical reactions.
Catalysts are compounds that speed up chemical reactions without being consumed or changed in any way. In living organisms, enzymes are essential for many biochemical processes, including the breakdown of food during digestion, the synthesis of molecules, and the facilitation of cellular processes. Enzymes help maintain vital biochemical processes, maintaining the fundamental activities of life, by reducing the activation energy required for a reaction.

Answer:
A tumor :) i just ask my biology teacher
The mass of cells formed a result of accelerated rate of division is called tumour.
CELL DIVISION:
All living cells are capable of replicating themselves and this is done via the process of cell division. However, the rate at which cell division occurs must be regulated.Due to series of reasons like mutation, cells can lose the ability to regulate their cell cycle leading to a proliferation in the rate of cell division. Uncontrollable increase in the rate of cell division leads to the formation of a mass of cells called TUMOUR.

Runners only have enough stored ATP in their muscle cells to run for about five seconds. Which answer correctly explains how the runner's body adjusts to the longer distance, for example, a marathon (42.1 km)?
Answer Options:
A: The runner's body will convert stored fat molecules into energy.
B: The runner's body will create the needed energy by breaking down proteins.
C: The runner's body will supply the needed energy by producing starch.
D: The runner's body will produce the energy by activating the Golgi apparatus.
Answer:
A: The runner's body will convert stored fat molecules into energy.
Explanation:
When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.
If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.
The runner's body will convert stored fat molecules into energy.

Describe the relationship of dissolved materials inside and outside a cell in isotonic, hypotonic,
and hypertonic solutions.
PLEASE HELP ASAP!! WILL MARK BRAINLIST TO FIRST WHO ANSWERS!
hypertonic is when blood cells shrivel under hot temperatures
isotonic is equilibrium between concentration of blood and salt
hypotonic is less concentration on outside compared to inside
Answer:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
