Answer:
(c) unicellular eukaryotic
Explanation:
Firstly, all prokaryotic cells are unicellular, they cannot be multicellular, so be cannot be correct.
Both Chlamydomonas and Paramoecium are single-celled organisms, so must be unicellular prokaryotic (a) or unicellular eukaryotic (c).
Chlamydomonas and Paramoecium are eukaryotic. They have membrane-bound organelles like a nucleus and food vacuoles. They are examples of protists.

Which body systems interact to regulate blood pressure?
Answer:
In addition to the local control of blood flow, global control of blood flow including changes in cardiac output and control of arterial BP is mediated by the autonomic nervous system. Global neural control of arterial hypertension is essentially through the sympathetic nervous system (SNS).

Black fur(B) in quinea pigs is dominant over white fur(b). Find the probability of a white offspring in a cross between two heterozygous guinea pigs. (Hint: draw a punnett square)
A.75%
B.0%
C.50%
D.25%
E.100%
Both the Parents have the genotype (Bb) then the offsprings in the F1 generation will have BB, Bb, and bb genotypes and black fur and white fur as phenotypes. Thus, the correct option is D.
What is Punnett Square?The Punnett square is a square diagram used to predict the genotypes of a particular cross or breeding experiment. The diagram is named after Reginald C. Punnett, scientist who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
In the given question, the genotype of both the parents is Bb (heterozygous) where, B is the dominant character (black fur) and b is the recessive character (white fur). The genotype and phenotype of the offsprings can be determined by this diagram.
The punnett square is attached with the answer.
25% of the offsprings will have Black fur and homozygous condition (BB)
50% of the offsprings will have Black fur and heterozygous condition (Bb)
25% of the offsprings will have white fur and homozygous condition (bb)
Therefore, the correct option is D.

Answer:
D. None of the above
Explanation:
Energy transformation is the process of transfer and conversion of energy from one species to another. None of the above is not an example of energy transformation. Thus, option D is correct.
What is energy transformation?Energy transformation is the process in an ecosystem that includes the conversion of energy from one level to another in the food chain or the metabolic reactions.
Photosynthetic reactions under the sun, herbivores feeding on producers, and predators feeding on the primary consumers are examples of energy conversion as it is continuously passing the energy to another species in the ecosystem.
Therefore, none of the above is not an example of energy transformation.

A human eats a meal and afterward their blood glucose levels rise. Explain how the human body responds to return their blood glucose level to normal.
Answer:
Explanation:
The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.
Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).
Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal
How does competition shape communities?
Answer:
In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.
Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.
In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.
Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.

Which of the following is one of the largest carbon reservoirs on earth?
A. Limestone
B. Amazon rain forest
C. Fossil fuels
D. Atlantic Ocean
From the options The Largest carbon reservoirs on earth is : ( A ) Limestone
The Largest carbon reservoirs on earth includes the Earth crust ,Oceans and fossil fuels. Limestone makes up about 15% of the earth's crust ( sedimentary ) therefore it is the largest carbon reservoir out of all the options given above.
Limestones are used as raw materials for the production of cement and other building/construction materials.
The Earth crust contains about 50,000,000 g/tons of Carbon in total while the oceans contain about 40,000 g/tons of carbon which is followed by Fossil fuels at 10,000 g/tons
Hence we can conclude that the Largest carbon reservoir is Limestone

what is the difference between Resilience and Resistance in ecosystem?
Answer: Rate and Abiltiy
Explanation: Resistance is the ability for an ecosystem to remain unchanged when being subjected to disturbance or disturbances. Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state.
Resistance is an ecosystem's ability to withstand disruptions. Resilience is an ecosystem's ability and rate to recover from disturbances.
What is Resilience and Resistance in ecosystem?Because of a population's resistance or resilience, it may be possible for that population to survive a disturbance. In general, the capacity of a population (or community) to tolerate the disturbance is referred to as its resistance, while the capacity to recover after being affected by the disturbance is referred to as its resilience.
Resilient ecosystems contribute to social and economic well-being by providing a solid base for different sectors (fishing, recreation, and tourism) and reliable ecosystem services that improve quality of life. Resistant ecosystems can keep their structure, processes, and functioning when stressed or invaded.

An igneous rock has small, dark crystals. Which statement also accurately describes this rock?
It is an intrusive rock.
It has a coarse texture.
It was found on Earth’s surface.
It was formed from slow cooling.
Answer:
It was found on Earth’s surface.
Explanation:
Igneous rocks are formed either on the surface of the Earth or deep in the Earth's crust. Those formed on the surface of the Earth are called "Extrusive Igneous Rocks" while those formed in the crust are called "Intrusive Igneous Rocks."
An igneous rock which has small, dark crystals is an extrusive igneous rock (this makes the first choice incorrect). It was formed through "rapid cooling," thus, it's texture is fine (this makes the last two choices incorrect).
Since it is an extrusive igneous rock, it can be found on the Earth's surface. This makes the third choice correct.
