“How might an energy requirement affect an individual who has a cancerous tumour?”
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).
What elements are needed to carry out photosynthesis? Select all that apply.
Answer:
You need carbon dioxide, sunlight, and water.
Explanation:
Answer:
1.
1.Light or photochemical reactions.
They require the presence of sunlight, which is transformed into chemical energy usable by organisms in the form of ATP, these reactions occur in thylakoids, and for their more detailed study, photochemical reactions are classified as cyclic photophosphorylation and non-cyclic photophosphorylation.
2.Carbon fixation reactions or reactions in the dark.
They require or not the presence of sunlight, and they are reactions that will occur in the stomata.
3.Chemosynthesis.
They take inorganic compounds and O2 from the environment and combine them inside their cells and as a result of these reactions energy is released (exergonic reactions) applying it in the synthesis of ATP (endergonic reactions), forming inorganic by-products.
Biological importance of photosynthesis:
Photosynthesis is surely the most important biochemical process in the biosphere for several reasons:
1. Every year some 200,000 million tons of carbon is used in the photosynthetic process.
2. The synthesis of organic matter from inorganic is carried out mainly through photosynthesis; that will go from some living beings to others through the food chains.
3. Produces the transformation of light energy into chemical energy, necessary and used by living beings.
4. Oxygen is released, which will be used in aerobic respiration as an oxidant.
5. It is the cause of the change produced in the primitive atmosphere, which was Anaerobic and reductive.
6. The energy stored in fossil fuels such as Coal, Oil, and Natural Gas also depends on it.
7. It is responsible for maintaining the necessary balance between Autotrophic and Heterotrophic beings.
8. During the process, dioxygen is released into the atmosphere, which implies:
Food chains and food webs are....... used to describe energy transfers
Answer: As it goes down in the food chain, and as the energy is passed, only 10% is kept as energy- the rest is lost as heat.

A bird that can easily out complete other birds for its food and that can produce many eggs has high what?
Answer:
Fitness or aptitude
Explanation:
Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.

What cell part supports the structure of the system plant cell
Answer:
The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders). The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.

What can a person do to prevent barriers to exercise? Select three options.
Answer:
Explanation:
Three things that anyone can do to prevent this would be
understand myths about working out
look for inexpensive classes in the area
take a physical education course at school
Most barriers to exercise revolve around becoming discouraged/depressed about the results due to having unrealistic and high expectations. Learning about what you can expect realistically from a set routine will greatly increase motivation and prevent such barriers. The same applies to learning which routines and diets work best and all of this can be learned by taking physical education courses or classes near you.
Answer:
understand myths about working out
look for inexpensive classes in the area

are cell membranes in plant or animals or both?
Answer:
Both
Explanation:
Answer:
Cell membranes are in both Plant and Animals cells.
Explanation:
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane, they both give the plant structure and support. Animal cells simply have a cell membrane, but no cell wall.

Name two types of proteins that regulate the cell cycle. How do these proteins work?
Answer:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
Explanation:
I hope this helps :)
The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.
What are Proteins?
Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.
Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.
Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).
