Chorionic villi are more prolific Select one: a. Adjacent to the yolk sac b. Opposite the cervical os c. Near the implantation s
Ann [662]

Answer:

Adjacent to the yolk sac

Explanation:

Chorionic villi are microscopic and fingerlike projections found near the placenta which contain capillaries, increase surface area of blood that allow blood to flow and transfer nutrients from the mother to the fetus. The chorionic villi is adjacent to the yolk sac because it developed from the yolk sac, villi can extend and contact maternal blood vessels thereby nourishing the embryo and transfering nutrients from the mother to the fetus.

How does Overpopulation affects our lives today ??
Mnenie [13.5K]

No Clean Water: We may live on a water planet, but 97.5% of that water is ocean and other undrinkable salt-filled sources. Only 2.5% of the water on this planet is fresh, and of that, 1% is either too polluted to be consumed or entirely unreachable. Much of it remains frozen in the form of polar ice caps. All told, less than 1% of the planet’s freshwater resources are available for consumption.

Lower Life Expectancy: Thanks to medical intervention, human beings can live to be up to 100 years old — as long as they live in developed countries where they have access to that medical care. One study, done by researchers at Harvard, found that the majority of population increases over the next 40 years or so will be in less developed countries.

Climate Change: We’ve been seeing the results of climate change firsthand in the dramatic weather patterns of 2017 — multiple category five hurricanes, dramatic wildfires and floods, and other atypical weather patterns that are threatening both lives and property.

During the process of dna replication, the strand provides a blueprint for the production of a new complementary strand, resulti
KatRina [158]

The two DNA strands unwind from one another during semi-conservative replication, and each serves as a template for the synthesis of a new, complementary strand. Two DNA molecules are produced as a result, each with one original and one new strand.

The act of duplication is referred to as replication. DNA replication is the first step in inheritance in molecular biology. The central dogma explains how the DNA replicates itself, codes for the RNA during transcription, and then codes for the proteins during translation.

On several sources of replication along the DNA template strand, DNA replication takes place (antinsense strand). One original strand and one freshly synthesized strand are included in every copy. Although it should be guaranteed that both copies are identical, Each strand of the double helix would act as a template for the manufacture of a new strand, according to the structure of DNA (which was discovered by James D. Watson and Francis Crick in 1953). The process by which freshly created strands united with template strands to create two double helix DNA molecules was unknown.

1. True or False: Water vapor is only visible on really cold days where the air temperature is below freezing.
Aleonysh [2.5K]

Answer:

The correct answer is - False.

Explanation:

Water vapor is water in its gaseous state. Water vapor is totally invisible, an individual can not see water vapor in any situation with naked eyes. Fog, clouds, mist are not the water vapor as they contain liquid water or droplets.

Water vapor is essential for the weather and climate, without water vapor there would be no rain, snow or clouds as require water vapor to form.

Thus, the correct answer is - false.
