What is DNA polymerase?
Answer:
A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex

Genetic mutations introduce new gene forms in a population. For instance, the mutation that affects
hemoglobin alters the shape of the red blood cell and makes it sickle-shaped. Which statement
below would explain why the sickle-cell mutation has spread through the gene pool?
A. There is a selective advantage to having Sickle Cell Anemia.
B. This kind of mutation demonstrates a common ancestor.
C. The sickle cell mutation has no benefit.
D. Sickle cell anemia increases the risk of death.
Answer:
B- this kind of mutation demonstrates a common ancestor.
Explanation:
in order to have sickle cell anemia you need to have both recessive alleles from both parents, this recessive allele has to be continuous passed down from generation to generation on both sides, which shows a common ancestor from long ago

Which list shows the correct order of processes that occur before and during ovulation?
egg released from ovary - hormones send signal > egg travels to fallopian tube
O egg travels to fallopian tube → egg is released from ovary → hormones send signal
O hormones send signal → egg travels to fallopian tube > egg released from ovary
O hormones send signal → egg released from ovary → egg travels to fallopian tube
hormones send signal --> egg released from ovary --> egg travels to fallopian tube

Explanation:
Which of the following describes the result of independent
assortment and crossing over during meiosis?
A: it creates genetic differences in sperm and egg
B: it produces higher quantities of sperm and egg
C: it produces individuals that are very similar to their parents
D: it makes fertilization go smoothly
Answer:
A.)
Explanation:
Independent assortment and crossing over is important because it creates genetic variation between gametes. This immediately eliminates (C) and in no way does crossing over or independent assortment cause more gametes to be produced so cross out (B). Only (A) and (D) is left, while both answers makes sense, (A) is the better one.
Meiosis takes place in the germ cells and give rise to haploid gametes. Due to the events including crossing over and independent assortment, it causes genetic differences in sperm and egg, i.e., option A.
What is crossing over?Chromosomal crossover also referred as crossing over, represents the exchange of genetic material during gamete formation,
It occurs between two non-sister chromatids of homologous chromosomes that results in recombinant chromosomes.
This creates genetic differences in the sperms and eggs.
Thus, the correct option is A.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

Answer:
Terrestrial ecosystems are known for their diversity; they are grouped into large categories called biomes. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them. For example, there is great variation in desert vegetation: the saguaro cacti and other plant life in the Sonoran Desert, in the United States, are relatively abundant compared to the desolate rocky desert of Boa Vista, an island off the coast of Western Africa
