5 0

Answer:

Option B

Explanation:

The upper mantle along with the some portion of crust together makes the lithosphere.  

Lithosphere is bounded by the atmosphere and primarily consists of rock and plates. There are two types of oceanic lithosphere – a) Oceanic Lithosphere and b) Continental Lithosphere

The living organism live on the top most layer of earth i.e the crust which consist of geographical land forms and soil

Hence, option B is correct

Which group of non-prokaryotic organisms studied in microbiology typically have two life cycle stages: trophozoite and cyst?
uranmaximum [27]

The correct answer is Protozoa.

A class of single-celled, non-prokaryotic organisms known as protozoa.These could either be parasitic or free-living in nature. These are heterotrophs that procreate via binary fission in an asexual manner. Numerous unrelated or tangentially related organisms make up the Protozoa. Sarcodina, Flagellates, Ciliates, and Sporozoans are the four main divisions. There are two stages in the life cycle of certain protozoa: the proliferative stage (trophozoites), and the resting stage (cysts). Trophozoites are the proliferative stage of the protozoa, which is when they divide and reproduce. The protozoa can tolerate adverse environmental circumstances like toxic chemicals, intense heat, and nutrition and water shortages because of their resting cyst shape.

In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.

After receiving information on various forms of birth control, a young couple decides to use a barrier method because they would
Makovka662 [10]

Answer:

The correct answer is diaphragm.

Explanation:

One of the barrier methods of controlling birth is the diaphragm. It is abstemiously efficient, with a one-year failure rate of approximately 12 percent with the typical application. It is positioned over the cervix with spermicide prior to having sex and is left in position for about 6 hours post-sex.  

It is a rubber barrier that holds the spermicide against the cervix. The spring in the diaphragm's rim produces a seal against the walls of the vagina. The diaphragm covers the cervix and physically inhibits sperm from getting inside the uterus via the internal orifice of the uterus. Basically, the diaphragm has an application with spermicide, and it is broadly considered that the spermicide substantially enhances the efficacy of the diaphragm.
