This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).Which indicates how evidence of climate change supports the theory of continental drift?
O coal fields in several continents
O volcano formation
O glacial evidence found in South Africa
O folded mountains in Africa and South America
Glacial evidence discovered in South America demonstrates how climate change evidence has bolstered the notion of continental drift. Folded mountains in Africa and South America. Thus, the correct option is D.
Climate change is happening all across the planet on a daily basis. This is primarily due to human activities that have had an impact on the atmosphere and the earth.
What is continental drift?Continental drift is basically the hypothesis that the continents once constituted a single landmass, disintegrated, and drifted to their current places.
The discovery of glacial evidence in South America has led to a greater acceptance of the continental drift idea.
Finally, we can conclude that glacial evidence discovered in South America demonstrates how climatic change evidence supports the hypothesis of continental drift.

In DNA replication, continuously synthesis occurs on the leading strand
Answer:
I think the answer is A. toward the origin of replication.
Explanation:
I hope this helps! Correct me if I am wrong.
In DNA replication, continuous synthesis occurs on the leading strand toward the origin of replication. Therefore option A is correct.
In DNA replication, continuous synthesis occurs on the leading strand, which is the template strand that runs in the 3' to 5' direction.
DNA polymerase synthesizes the leading strand in the 5' to 3' direction, moving toward the replication fork's origin. The replication fork is the point where the DNA strands are unwound and replication begins.
As the replication fork opens, DNA polymerase adds nucleotides in the direction of the origin of replication, continuously elongating the leading strand.
The lagging strand, on the other hand, is synthesized discontinuously in the opposite direction, creating Okazaki fragments, which are later joined together by DNA ligase.
Therefore option A is correct.

temporal isolation
O mechanical isolation
adaptive radiation
hybrid breakdown
Charles Darwin's finding that the finches on the Galapagos islands looked different from the mainland finches despite their common ancestry from South America is an example of C. adaptive radiation.
What is common ancestry?Common ancestry refers to blood relationships. Thus, two species may have common ancestry if they are related by blood.
According to Charles Darwin, common ancestry explains the similarities between different species.
However, a rapid increase in the number of species with a common ancestor, characterized by great ecological and morphological diversity results from adaptive radiation.

Peptic ulcers are caused by damage to the wall of the stomach by the acids that help digest food.
This can be caused by the failure of
A. tight junctions
B. adhering junctions
C. gap junctions
D. plasmodesmata
E. adhering and gap junctions
Peptic ulcer disease can be caused by the failure of tight junctions. Thus, the correct option is A.
What is Peptic ulcer disease?Peptic ulcer disease may be defined as a circumstance in which bitter and painful sores or ulcers evolve in the lining of the stomach or the first part of the small intestine which is the duodenum.
A tight junction is responsible for lining the wall of the intestine or stomach. It helps in the prevention of the passage of digestive enzymes through the space between adjacent locations inside the stomach or small intestine.
If this junction breaches, it results in damage to the wall of the stomach by the acids that help digest food and causes the peptic ulcer disease which is infected by a bacterial organism known as Helicobacter pyroli.
Therefore, it is well described above.

How does the melting of icecaps affect climate change
Answer: it can contribute to rising sea levels, higher overall climate, & affect native wildlife.
Explanation: (1) Melting ice can add more water to the ocean, which in turn sea levels rise due to this affecting coastal communities. (2) sea ice such as snow caps reflect 50 percent of solar radiation, (thick sea ice covered with snow reflects even more radiation, about 90 percent) this reflecting keeps global temperatures in check. (3) native arctic wildlife, such as porpoises, fish, avians, and land-mammals are affected as their homes are shrinking, leading to less food and areas that they are adapted too.

Scale insects can be serious pests for citrus fruits. Severe infestations of scales result in falling twigs and branches until the affected tree dies. In the early 1900s, California citrus growers sprayed their trees with cyanide gas to kill scale insects. By 1914, some scale insects were surviving the spraying, and eventually the whole population showed resistance to cyanide. Which of the following statements best explains how resistance to cyanide spread in the scale insect population?
A. Insects with a resistance gene survived the first cyanide sprayings and passed the gene to their offspring.
B. Parasites infecting the insect population carried the trait from insects with a resistance gene to insects without a resistance gene.
C. Predators put greater selection pressure on insects with a resistance gene than on insects without a resistance gene.
D. Insects without a resistance gene underwent mutation upon contact with the cyanide to acquire resistance.
Individuals exposed to a damaging factor might mutate and resist the nosive effects. D) Insects without a resistance gene underwent mutation upon contact with the cyanide to acquire resistance.
What is resistance?The term resistance refers to an inheritable change in the population sensitivity, reflected through the exposure of individuals to damaging factors (insecticides, for instance) that affects the population.
A genetic modification -mutation- might occur in some of the exposed individuals, leading them to survive under the effects of these factors.
Mutated individuals spread this new character in the population, which evolves with the capability of tolerating the element that would normally affect it.
In the exposed example, some of the exposed individuals developed a mutation after the cyanide exposure and got to survive. These individuals could mate and reproduce, transmitting this new resistant character to the following generations.
The correct option is D. Insects without a resistance gene underwent mutation upon contact with the cyanide to acquire resistance

What is effects of solid wastes?Solid wastes are those materials that are discarded from factories and facilities which may contain chemicals that are able to pollute the water bodies.
When they are being washed into the water body, they build up in the body of fishes in a process called bio magnification.
Bio magnification is a process whereby chemicals that are washed into the water bodies accumulate on the body of animals (wildlife) through eating of aquatic animals.
When animals feed on these fishes, it harms their health with time.
