The differee between Riversible Inhibition and
irrversibel Inhibition
Answer:
Explanation:
Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation)
In contrast, reversible inhibitors bind non-covalently and different types of inhibition are produced depending on whether these inhibitors bind to the enzyme, the enzyme-substrate complex, or both.

A scientist discovers a fossil of an animal and places it in the fossil record. The organism’s bones are similar to the bones of animal T, which appears earlier in the fossil record. Which conclusion is most reasonable?(1 point)
The fossils came from the same organism.
The fossils are from an ancestor of animal T.
The fossils are from animals that lived at the same time.
The fossils are from a descendant of animal T.
2. Why do organisms evolve?(1 point)
Organisms naturally select traits that help them survive and reproduce.
Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Changes in the environment cause organisms to change.
Organisms make changes to help them survive and reproduce in their environment.
3. Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows:
Animal A and animal B have somewhat similar structures.
Animal A and animal C have very similar structures.
Animal B and animal C have very similar structures.
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the scientists’ observations, which order is the most reasonable?
(1 point)
B, A, C
A, C, B
A, B, C
C, B, A
4. Scientists discover fossilized bones from two different animals. The scientists consult the fossil record to learn more about the fossils. Which question will the fossil record best answer?(1 point)
How are the animals related to modern animals?
What killed the animals?
Which animal was better equipped to survive?
Which animal is older?
Answer:
1) The fossils are from a descendant of animal T.
2) Organisms with traits that help them survive and reproduce in their environment pass on those traits.
3) A, C, B
4) Which animal is older?
5) Fossils of Archaeopteryx have traits of both dinosaurs and birds.
Explanation:
The fossil records are used to show that modern creatures are distinct from those from the past and to illustrate how evolution has progressed, hence for questions 1- B, 2- B, 3- D, for 4- D.
What is the fossil record?Due to individual variation within a population, certain members of the population are more likely to live and procreate under a specific set of environmental conditions.
The majority of these people live longer and have more children, passing on their beneficial features to the following generation.
C has the most similar structure, B has the second most similar structure, and A has the least similar structure.
Two separate creatures' petrified bones have been found by scientists. To discover more about fossils, the experts consult the fossil record.
Therefore, modern creatures are distinct from those from the past, and to illustrate how evolution has progressed, hence questions 1- B, 2- B, 3- D, for 4- D.

Match the sensory characteristic with how it is coded by the nervous system. - Sensory modality - Location of the stimulus - Intensity of the stimulus - Duration of stimulus A. Which sensory neurons are activated B. Receptive fields C. Frequency of action potentials D. Duration of action potential train (i.e., continued firing of action potentials in sensory neurons) E. Size of action potential F. Duration of a single action potential
Answer:
a) Which sensory neurons are activated
b) Receptive fields
c) Frequency of the action potentials and size of action potential
d) Duration of action potential train and Duration of a single action potential
Explanation:
Sensory modality : The sensory modality is Which sensory neurons are activatedLocation of the stimulus : The location of the stimulus is in the Receptive fieldsIntensity of the stimulus : The Intensity of the stimulus represents the frequency of the action potentials and size of action potential Duration of stimulus : The duration of the stimulus is Duration of action potential train and Duration of a single action potentialFernanda is feeling sick and goes to the
doctor. Upon taking a blood sample, the
doctor observes that Fernanda's cells
contain a pathogen that seems to be made
of small cells with no nucleus. What type of
infection does Fernanda have?
bacterial
fungal
none of the above
viral
Answer:
bacterial
Explanation:
A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.
According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.
Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.
Fish sperm consists mostly of the male fish's DNA. If tested chemically, there would be relatively

Answer:
Based on knowledge of enzymes and the given data, it can be concluded that Tcn-protease is most likely active in the alligator's stomach and Wx-protease is most likely active in the alligator's intestines. As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.
Explanation:
A pH less than seven is acidicA pH of at or around seven is neutralA pH of more than seven is alkaline (basic)Besides plants, list 2 other organisms that carry out photosynthesis.
