Answer:The correct answer is B
Explanation:
I hope this helps you out!
From the image, the letter that represents the enzyme is B.
Enzymes are substances, made up of proteins, which are capable of speeding up the metabolic reactions in the human body.
There is a theory that explains the mechanism of action of enzymes. This is called the enzyme lock and key theory.
This theory states that enzymes bind to substrates temporarily forming enzyme-substrate complex that appears like the fitting of a lock and key.
This simply means that the same way a particular key can only fit into a particular lock is the same way a particular substrate must combine with a particular enzyme for a reaction to occur.
From the diagram,
B represents the enzyme with an active site which must fit into a substrate
A represents the substrate.
Therefore, the the letter that represents the enzyme is B.

Which theory directly
contradicts the concept of
absolute zero?
A. Gravitational Theory
B. Kinetic Theory
C. Matter Theory
Answers
A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.
What theory directly contradicts concept of absolute zero?All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).
Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.
Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.
What are prokaryotes?The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.
Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.
A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

The Flowchart is in the picture below. I hope it would be helpful for you.
A nucleotide is a compound containing three component units namely a pentose sugar, a heterocyclic nitrogenous base and a phosphate group. The nitrogenous base present may be either purines or pyrimidine.
What is sickle cell anemia?The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.
Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.
SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.

How can students in the photograph use the net to sample the invertebrates in the river.
Answers
Answer and Explanation:
Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.
There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.
Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.
Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.Classify each planet as an inner planet or an outer planet.

Marine iguanas feed on seaweed. Seaweed contains starch Starch is digested by enzymes in the digestive system. Explain why the shape of an enzyme is important for digestion.
Answers
Answer: The enzyme is a catalyst that speed up the rate of the reaction.
Explanation:
The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

Answers
The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes. a) oceanic crust at convergent boundary b) heats up.
What are convergent boundaries?Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.
In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices. The Himalayas and Los Andes are examples of these collisions.
Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.
When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.
