Answer:
When a substrate is added in water, the enzyme will cause the substrate to dissolve in water. Increase in temperature will cause better functioning of the enzyme and more solute to be dissolved until an optimum temperature. Optimum temperature can be described as the temperature at which the activity of the enzyme is highest.
After optimum temperature is reached, the enzyme will get denatured and the substrate will no longer be able to dissolve in water.
Darwin’s theory suggests that there is some evolutionary advantage towards beetles because they can use camouflage as a defense strategy against predators.
Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
Answer:
The correct answer is option d.
Explanation:
An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.
One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.
In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.
Answer:
D) Asexual reproduction produces offspring that are genetically identical to the parent.
Explanation:
I am honestly not quite sure of this answer, but I was trying to read up on the topic and this is the answer I'm most confident in. It would make sense that the offspring are genetically identical to the parent because they would have no where else to get their genes/mix to form new ones. I really hope this helps!
