chemical reactions involve changes in the energies of the molecules involved in the reaction
During a chemical reaction, bonds are formed or breaked to make new products which may complex than the reactants. Energy changes can be happened in a reaction during rearrangement of atoms. Thus, all of the statements are correct.
What is a chemical reaction?
A chemical reaction is a chemical change occuring for matter where the atoms are regrouped into new products through bond making or bond breaking or both.
The change in energy during a reaction is called enthalpy change, where each reactant is associated with a standard energy and the energy may change with temperature or other external factor.
There may more than two reactants and some reactions are completing through several stages and may lead to complex products which are having entirely different properties from the reactants. Therefore, all the given statements about chemical reactions are correct.

Task 2: The Circulatory system pumps blood and oxygen to all of the organs in your body to keep them working, The respiratory system takes in oxygen and the circulatory system takes that oxygen to all parts of the body. The circulatory system also takes nutrients from food that is digested by the digestive system to all parts of the body to keep them working as well.
Task 3: The Endocrine system is important to controlling the human body but for these reasons I believe that the nervous system is more important. I think that the Nervous system is more important to controlling functions and processes in the human body because without the nervous system messages from and to your brain can not be relayed. Without the nervous system you would not be able to move or feel pain when you have been injured.

Answer:
Large areas of the earth with similar climate and ecosystems are called biomes.
Explanation:
Biomes are defined as areas of the planet with common characteristics, such as animal and plant species, as well as climate, which is why it is called a bioclimatic landscape.
When a relationship is established between an ecosystem —with all its biotic and abiotic components— and the climate in a given area, reference is made to a biome. Consequently, a biome represents large areas of land with similar geographical, climatic and biological conditions.
The other options are not correct because:
Communities are groups of individuals with common characteristics. Populations are individuals of the same species that occupy a certain space in a certain time. Organisms are synonymous with living beings.What is the genotype of a person with type A blood, who had a father with type O blood?

Which of the following required a protein channel (carrier) to allow molecules to cross the cell membrane (plasma membrane)? (Hint: multiple answers)
A. facilitated diffusion
B. osmosis
C. active transport
D. diffusion
Answer:
the answer would be c
Explanation:
The process that entails the movement of protein channel (carrier) through cell membrane (plasma membrane) as regards this question is C. active transport
Active transport can be regarded as a process involving the movement of molecules through the cellular membrane using cellular energy. Active transport is utilized by cells for accumulation of needed molecules. These molecules could be glucose as well as amino acids.Therefore, option C is correct.

How does mutation effect genes
Answer: When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth
Explanation:
Name and describe the three types of RNA's involved in protein synthesis?
Answer:
The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).
Explanation:
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Transfer RNA (tRNA) is a small RNA molecule that participates in protein synthesis. Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid.

Describe how pholem is affected if the leaves start to die off of a plant
Answer:
Phloem is responsible for carrying the products of photosynthesis from the leaves to the non-photosynthetic parts of the plant. As leaves die off, and photosynthesis is slowly reduced and then halted, phloem will no longer need to carry the sugars from the leaves into storage. Once the leaves die off the tree. As the tree prepares for winter it also produces ice nucleators and antifreezes that help keep the tree's sap from freezing in the winter.
Explanation:
organisms that use sunlight to produce energy-storage molecules are called- a.heterotrophs b. producers composers d. decomposers

How do catalysts affect a chemical reaction?
A. increase the activation energy
B.provide activation energy
C. lower activation energy
D. lose activation energy
Answer:
C: Lowering activation energy
Explanation:
A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.
What do you think happens in the atmosphere to cause rain, snow, and other types of precipitation?
Answer:
water is evaporated into the air then the water molecules get too heavy and come back down as snow/rain/ect
Answer:
When warm, wet air rises, it cools, and water vapor condenses out to form clouds. ... When ice crystals form high up in the cloud, and it's below the freezing point of water all the way down, then you get snow. But when there are alternating layers of air above and below freezing, you get other types of precipitation.

1. List how a cell transports across the membrane?
2. What are the types of passive transport?
3. Describe what is facilitated diffusion?
Answer:
1. this process continues until the substance is evenly distributed in a system.
2. depends on the cell membrane!
3. Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane.
Explanation:
1. The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration
2. passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.
3. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient
