A researcher prepares a suspension of mitochondria from tissue and monitors the respiration of the mitochondria by the rate of oxygen (O2) consumption in the presence of pyruvate. When the researcher adds an inhibitor of isocitrate dehydrogenase to the suspension, oxygen consumption (respiration) stops.
Answer and explanation:
The mitochondria are the organelle responsible for respiration, which leads to the production of ATP - the most important molecule in energy transfer.
For respiration to happen, there are several processes involving chemical reactions that take place in the mitochondria. These mechanisms are: oxidative decarboxylation, Krebs cycle, and oxidative phosphorylation. Glycolysis is also important for these processes to occur, but this particular case happens outside of the mitochondria.
Pyruvate is an important precursor of the Krebs cycle, also called 'the citric acid cycle'. The researcher observes the functioning of the mitochondria in presence of pyruvate, but then adds an inhibitor of isocitrate dehydrogenase. This inhibitor cancels out the action of the isocitrate dehydrogenase, which is a key enzyme in the Krebs cycle. By inhibiting this enzyme, the cycle cannot continue, and respiration stops.

Select the homologous structures.
a. human arm
b. whale's flipper
c. bird's wing
d. cat's leg
Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

what are the types of vaccine ?A vaccine can be defined as a biological preparation which provide an active acquired immunity to a specific infectious and transmissible disease.
A vaccine consist of an agent that has a similarity to the disease-causing microbe. Inactivated Vaccine are formed by inactivating a pathogen by applying heat or chemicals such as formaldehyde or formalin, it destroys the pathogen’s ability to replicate.
Attenuated vaccines are formed from different ways like passing the disease-causing virus through a series of cell cultures or animal embryos.
Toxoid Vaccine can be made by inactivating the toxin released from bacteria that causes disease symptoms, the organisms or viruses used in inactivated vaccines which can be done via treatment with a chemical such as formalin.
Subunit Vaccine use a part of a target pathogen to provoke a response from our immune system, which can be done by isolating a specific protein from a pathogen.

Can somebody please answer this quickly?
Answer:
I think it would be C, that is the only one that makes sense to me. Hope i can help
Explanation:
A farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.
Answer:
Explanation:
Selection is the greatest force that alters gene frequency and brings about variation that is evidence in a population. There are both natural and artificial selection.
Mutation is one of the force that alters population frequency it is an heritable change that is sudden and occur in the gene, it can be induced or caused naturally.
The insect survived the DDT used because over the years they have build immunity and resistance against the chemical, they now mutate and produce gene that becomes resistance to the chemical and now adapted or adaptable to the environment. Natural selection helps in the continuous perpetuation of the new phenotype and a new differential survival rate.

Find the hypotenuse of a right triangle whose legs both have a length of 5.
Answer:
Hypotenuse = 7.07 units.
Explanation:
The sides of the right angle triangle are the opposite and adjacent side; which are both equal in this case.
Given the following data;
Opposite = 5 units
Adjacent = 5 units
To find the hypotenuse, we would use the Pythagorean theorem given by the formula;
Hypotenuse² = opposite² + adjacent²
Hypotenuse² = 5² + 5²
Hypotenuse² = 25 + 25
Hypotenuse² = 50
Hypotenuse = √50
Taking the square root of both sides, we have;
Hypotenuse = 7.07 units.
