Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.

According to the concept of "survival of the fittest," if a population of birds eats worms that they find deep under ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.
What is natural selection?Natural selection is a process in which the only organisms that can adapt to the environment and its changing conditions are chosen by nature, such as in the case of the Darwinian finches. when different types of birds are present in the ecosystem and all can get their favorable food source, but when an adverse climate occurs and food is only available in deep ground, only long-beaked birds can survive because they can get food. This explains the survival of the fittest by the natural selection.
Hence, as per “survival of the fittest," if a population of birds eats worms that they find deep under the ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
A)Enzymes do not affect the energy of a reaction.
B)Enzymes slow down reactions so products can form.
C)Enzymes can be reused because they do not permanently bond with substrate.
D)Enzymes can only bind to other enzymes so the same product is formed each time.
Answer: C
Explanation: Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Enzymes can be reused because they do not permanently bond with substrate.
What are Enzymes?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Therefore, Enzymes can be reused because they do not permanently bond with substrate.

Turner syndrome occurs in females who instead of having two X chromosomes have either only one X chromosome or a fragmented X chromosome. Klinefelter syndrome occurs in males who have multiple X chromosomes. Consider the karyotype.
A karyotype indicates that a male has multiple x chromosomes.
Which individual is shown in the karyotype?
male with Turner syndrome
male with Klinefelter syndrome
female with Turner syndrome
female with Klinefelter syndrome
Answer:
male with Klinefelter syndrome
Explanation:
for an individual to be considered male he needs to have at least one Y chromosome
usually an individual with Klinefelter syndrome has two X chromosomes instead of 1 and 1 Y chromosome(XXY) but the karyotype can also be XXXY

More types of organisms exist now.
Fewer organisms have gone extinct in recent years.
Scientists invent new organisms that need to be classified.
Scientists continue to learn more about living things.
Answer:
The correct answer would be - Scientists continue to learn more about living things.
Explanation:

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?
Answer:
3.5264 x [tex]10^{7}[/tex]
Explanation:
The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.
In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.
So the short ton produced will be
= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102
= 3.5264 x [tex]10^{7}[/tex] short ton.
Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

What energy carriers can enter the electron transport chain in mitochondria to generate ATP?
Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).
Explanation:
The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.
