A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.
The correct answer is:
Option C. have a complementary shape to the substrate.
This can be explained as:
If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.Activation energy is the minimum amount of energy needed for the reaction.If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.Therefore, the active site should have a complementary shape to the substrate.

How are stem cells nurtured to form a tissue/organ?
Answer:
Stem cells have the capacity to proliferate and to differentiate into relatively mature cells of various types. Embryonic stem cells can become any organ in the body and do so when implanted into a blastocyst. In principle, then embryonic stem cells could be used to replace any organ in the body.

why does amino acids decrease in ileum
Answer:
The two major pancreatic enzymes that digest proteins in the small intestine are chymotrypsin and trypsin. Trypsin activates other protein-digesting enzymes called proteases, and together, these enzymes break proteins down to tripeptides, dipeptides, and individual amino acids.

Suppose that a cell is unable to replicate its DNA. Which of the following would NOT be present in this cell? ******ONLY ANSWER IF YOU KNOW THE ANSWER GIVING BRAINLIEIST******
Answer:
sister chromatids
Explanation:
Suppose that a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.
What is sister chromatid?Sister chromatid refers to replicated chromosome that are genetically identical.
Prior to every cell division, a cell must replicate its DNA in order to have an even distribution of genetic material in the daughter cells.
The result of DNA replication is sister chromatids, which carry individual identical DNA.
Therefore, if a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.

What organism are tertiary (3rd level) consumers
Answer:
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish.
Explanation:
Answer:
The larger fishes like tuna, barracuda, jellyfish, dolphins, seals, sea lions, turtles, sharks, and whales are tertiary consumers Explanation: They feed on the primary producers like phytoplankton and zooplankton, as well as secondary consumers like fish, jellyfish, as well as crustaceans.
Which of the following statements best compares reproduction in viruses with reproduction in single-celled protists? no links please
Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. Therefore, the correct option is (C).
Viruses require the cellular machinery of host cells to reproduce; single-celled protists reproduce on their own. The main difference between reproduction in viruses and single-celled protists lies in their reproductive processes. Viruses are obligate intracellular parasites that lack the cellular machinery required for replication. They rely on infecting host cells and hijacking their machinery to reproduce and create new viral particles. In contrast, single-celled protists are independent organisms capable of self-replication through various mechanisms such as binary fission, budding, or spore formation. They do not need a host cell for their reproductive processes. This fundamental distinction highlights the unique strategies employed by viruses and protists in propagating their species.Therefore, the correct option is (C).

Explanation:
if a bacterial cell is capable of taking up foreign dna, it is said to be what?
Answer:
competent
Explanation:
The uptake of foreign DNA from the environment is known as transformation
If a bacterial cell is capable of taking up foreign DNA, it is said to be competent.
What is competent?
Transformation is the process by which bacteria can absorb foreign DNA. In DNA cloning, transformation is a crucial step. After restriction digest and ligation, it takes place and transmits freshly created plasmids to bacteria.
Bacteria are chosen on antibiotic plates after transformation. Bacteria are extraordinarily adaptable creatures, with the rare capacity to take in and replicate (or copy) foreign DNA.
They gain an evolutionary advantage from this and are better able to withstand environmental changes. Bacteria, for instance, can acquire DNA that renders them immune to antibiotics.
Therefore, the term is competent for a bacterium that is capable of taking up foreign DNA.

According to urban anomie theory the impersonal nature of city life extends to situations that do not call for social involvement. Please select the best answer from the choices provided T F.
Answer:False
Explanation: right on Edge
The statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true, as urban anomie theory suggests that the impersonal nature of city life leads to the breakdown of social bonds.
What is urban anomie theory?According to this theory, the fast pace of urban life, the diversity of populations, and the emphasis on individual achievement can lead to a weakening of social ties and a breakdown of social norms and values. As a result, individuals may feel disconnected from others and from society as a whole, leading to a sense of alienation and a lack of meaning in their lives. This sense of normlessness and detachment can extend beyond situations that require social involvement, such as interactions with neighbors or participation in community events, to other aspects of daily life.
Hence, the statement "According to urban anomie theory, the impersonal nature of city life extends to situations that do not call for social involvement" is true.

Summarize the results and provide an explanation or reasoning for what was observed. How does light color affect the rate of photosynthesis? Why does the color of light matter?
Answer:
The lights higher on the light spectrum, like blue would have the fastest rate of photosynthesis because the energy is the highest. the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as mich as the other colors. The color matters because the color or wavelength of light does affect photosynthesis, which is how plants can create their own food.
