F. They can catalyze the same reaction repeatedly.
Answer:
They are necessary for a chemical reaction to occur
They increase the efficiency of chemical reactions
Enzymes are proteins that act as biological catalysts by speeding up chemical reactions. Substrates are molecules with which enzymes can interact, and enzymes convert substrates into other molecules known as products.
What is enzymes? Biochemical reactions are sped up by enzymes, which operate as biological catalysts. The most popular explanation proposes that enzymes bind to the substrate molecule and create a transition state. An energy barrier that the substrates must pass separates the products from the substrates as the reaction progresses.Digressionary enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most crucial digestive enzymes that break down proteins, carbs, and fats are produced by it.To learn more about Enzymes refer to:

How does a bacteria become antibiotic resistant?
Answer:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs resistant.
The same 600 N person lifts his 100 N carry-on bag upward a distance of 1.0 m. They travel another
10 m by riding on the "people mover." How much work was done in this situation?
Answer:
100J
Explanation:
The amount of work done here is 100J
Work done is the force applied along a particular distance.
In this problem;
Weight of the object = 100N
Weight of the person = 600N
Distance of raise = 1m
Distance traveled = 10m
Since work done is the force applied along a specific distance;
Work done = force x distance = 100 x 1 = 100J
What are 6 scientific facts about Spongilla lacustris?
Answer:
Physical characteristics: Freshwater sponges are crustlike, branched, or clumped. The texture is fragile and soft, and the color is whitish or green. Freshwater sponges have irregularly scattered and barely visible water-exit holes.
Geographic range: Freshwater sponges live in North America, Europe, and Asia.
Habitat: Freshwater sponges live in standing and running fresh water.
Diet: Freshwater sponges are filter feeders.
Behavior and reproduction: Scientists know little about how freshwater sponges behave. These sponges reproduce asexually by forming buds in late summer that spend the winter in a dormant state and emerge from the adult in the spring. Freshwater sponges reproduce sexually during the summer, giving birth to live larvae.

Answer:
D.) both a and c
Explanation:
Past observations made early in history as well as telescopes and space probes are very important in studying our universe and galaxies.
Space probes are increasingly gaining momentum as technological and scientific advancements are being made. Telescopes are used to see or picture objects that are very far away in space. Also, understanding the past records and historical data is essential for the study of the universe.Microscopes are not used in galactic studies. They are only used to study the world of micro-organisms.

Answer:
In order to be able to make proteins, RNA has to migrate or travel to the cell cytoplasm.
Explanation:
RNA, specifically messenger RNA (mRNA) is responsible for carrying the genetic information needed for make proteins, so it must migrate from the cell nucleus to the cytoplasm.
DNA transcription and RNA synthesis, as well as maturation, occur in the cell nucleus. From there, the mRNA must travel to the cytoplasm to meet the ribosomes and initiate protein synthesis.

A person with type A blood (unknown genotype) marries a person with type O blood. What blood types are possible among their children. (Show 2 crosses)
Answer:
If a person with blood type A, of unknown genotype, and a person with blood type O have offspring, the only possible blood types in children are A and O.
Explanation:
It should be noted that in the case of blood type A, the possible genotypes are A|A or A|O, while blood type O (recessive) will always have genotype O|O. Assuming that it is the father who has the blood group A:
♂ A|A or A|O
♀ O|O
- Cross 1: If the father possesses the dominant A characteristic on both alleles
Alleles A A
O A|O A|O
O A|O A|O
In this case all the offspring will have a blood type A, with a heterozygous genotype.
- Cross 2: If the father has blood type A, but with a heterozygous genotype
Alleles A O
O A|O O|O
O A|O O|O
50% of the descendants will be of blood type A, heterozygous
The other 50% will be blood type O.
Blood type is determined by the presence or absence of surface antigens A and B.
Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, and genotype O|O .Thus, depending on the genotype of one of the parents A|A or A|O, when crossed with a parent type O O|O, their children may have blood type A or O.

What is a blood group?Blood group is the classification of blood on the basis of the presence and absence of antibodies and antigens.
Given that, A person with type A blood (unknown genotype) marries a person with type O blood.
We don't know the genotype
If the unknown person is OO you get O.
The person is AA or AO you get A or O.
If the person is BB or BO you get B or O.
If the person is AB you will get A or B, there is no chance of an O offspring with an AB parent.
Thus, the possible blood group is A, B, and O.
