Which statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the reaction energy needed. The catalyst increases the concentration of products. The catalyst binds to enzymes to release substrates. The catalyst increases the concentration of reactants.
Answer:
The catalyst decreases the reaction energy needed.
Explanation:
The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.
Compared to reactions without catalysts, they are much faster because there is less activation energy needed.
Catalyst is any substance that causes or increases the rate of a chemical reaction without itself being consumed For example - enzymes are biocatalysts.
The catalyst can speed up a chemical reaction by reducing the activation energy or by changing the reaction mechanism.
The minimum amount of extra energy required by a reacting molecule to get converted into the product is defined as activation energy.
So, the correct answer is The catalyst decreases the reaction energy needed.
Other options-
The catalyst increases the concentration of products- incorrect. Catalysts do not affect the equilibrium concentrations of products or reactants. The catalyst binds to enzymes to release substrates- incorrect. The catalyst binds to the substrate and converts the substrate into products.The catalyst increases the concentration of reactants- incorrect.

How would you explain to an athlete why damaged joint ligaments and cartilages are so slow to heal following an injury?
Answer: They have little to no direct blood supply.
Explanation: “Ligaments and cartilage injuries are very common injuries for people who practice sports. Damaged joint ligaments and cartilage are slow to heal because these structures don't have a significant blood supply, which brings necessary fluid and nutrients to the injured place. These nutrients and fluids are essential for damage repairing. If ligaments and cartilage become injured, their limited blood and nerve supply result in a longer recovery and healing period.”
The reason why damaged joint ligaments and cartilages are so slow to heal
is as a result of little blood flow within them.
Cartilages and ligaments are connective tissues which help to connect
bones and other parts together. This part of the body has very little blood
flow and a result blood carrying nutrients aren't adequately supplied to the
region.
Different nutrients and compounds which promote healing and repair of
worn out tissues are found in the blood and failure to reach these regions is
why healing is slow.

The statement (C) is correct. The cellulose has more chemical bonds.
What do you mean by cellulose?Cellulose is an organic compound with the formula ₙ, a polysaccharide consisting of a linear chain of several hundred to many thousands of β linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.
Moreover, cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.
Hence, cellulose is an insoluble dietary fibre consisting of glucose polymers present in all cell walls of plants.

What is a similarity between a tulip and a crocodile? A function of both of their outer coverings is to reduce water loss. In both the tulip and crocodile the male reproductive organ is the testes. The tulip and crocodile both have internal skeletons that support them. The outer coverings of the tulip and crocodile both protect the organism.
Answer:
A function of both of their outer coverings is to reduce water loss
Explanation:
Crocodile and Tulips are both distinct species of organisms. Crocodile belongs to Kingdom Animalia while Tulips belong to Kingdom Plantae. However, despite their elaborate differences, they do have one feature in common, which is the function their outer covering performs.
Tulips are temperate plants I.e. like cold regions, hence, their outer covering functions to prevent excessive loss of water. On the other hand, the scaly skin of the crocodiles help them against water loss. This is common between the two different species.
