Describe the kind of transport the paramecium uses to remove water from its cytoplasm. (1 point) b. Explain the relationship between the contractile vacuole activity and the environmental salt concentration. (1 point) c. Predict what would occur in the paramecium if a biological toxin blocked the activity of the contractile vacuole. (1 point) d. Justify your prediction in part C. (1 point)
Answer:
Passive transport .
Explanation:
Passive transport is a kind of transport which is used by Paramecium to remove excess water from its cytoplasm. There is a inverse relationship between the contractile vacuole activity and the environmental salt concentration because if there is salty environment, the contractile vacuole did not their function because there is difference in pressure and the water moves outside when there is salty environment. Bursting of paramecium occur if a biological toxin blocked the activity of the contractile vacuole because no excess water moves to outside environment.

Complete question:
Hot summers and cold winters, topsoil rich in organic material, annual precipitation of 75 to 125 cm (30-50 in), and many hardwood trees are characteristics of the:
A. temperate deciduous forest.
B. temperate grassland.
C. temperate rain forest.
D. boreal forest.
E. chaparral.
Answer:
A. temperate deciduous forest
Explanation:
Temperate deciduous forest
Temperate deciduous forest is one of the biomes that extends to the south of the boreal forest, expanding in regions where temperatures are not that cold, and precipitations are abundant. The temperate forest is not continuous, it extends between 30º and 60º latitude in both hemispheres, and along with the continental extremes, influenced by the oceans. Vegetation suffers changes through the four seasons, which are clearly differentiated. Temperate forest characterizes for having deciduous trees among other phanerophyte species. Due to environmental conditions, these plants need to lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. They need to store different nutrients that will be used for plant growth during the following spring. Foliage reappears again during spring and summer.
Winters are cold and summers are warm. Precipitations are abundant, between 750 and 1500 annual mm, and they are well distributed during the year. Usually, there is a small water deficit at the end of the summer, while during the spring there is water excedent in the ground. Soils are very fertile and deep, due to the leaves´ loss that provides nutrients to the soil and protects it from erosion.

Describe the processes that turn metamorphic rock into igneous rock and the energy that powers the processes.
So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.
But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.

Goats and sheep belong to the same family but different genera. While they often live together in the same pastures, the hybrid offspring that are occasionally produced between the two species rarely survive. When such a hybrid does survive, it is usually sterile. Which of the following best explains the mechanism that maintains reproductive isolation between goats and sheep?
a. Gene flow is prevented because the two species belong to different trophic levels and therefore do not share a food source.
b. Habitat isolation creates a prezygotic barrier between the two species.
c. The males of one species and the females of the other species are fertile at different times.
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Answer:
d. The two species have a different number of chromosomes, resulting in a postzygotic barrier.
Explanation:
The two species i.e. sheep and goat have different number of chromosomes that resulting in a postzygotic barrier. Sheep has 56 number of chromosomes whereas goat has 60 number of chromosomes that causes postzygotic barrier in the offspring produced from the fusion of these two species. Postzygotic barrier leads to the creation of a hybrid that is sterile and unable to produce offspring because of difference in chromosome number.

Drag two black mice into the Parent 1 and Parent 2 boxes. Click Breed to view the five offspring of these parents. What do the offspring look like
Answer:
The correct answer is - All offsprings are black-furred mice.
Explanation:
In this case, the parent mice are black and a cross between these mice produces offspring one allele from both parents. Here, black fur is dominant over white fur.
All the babies are with dark fur colors, no whites as black is a dominant color, so it produces black due to cross between two true breeds.

Kudzu, a vine native to Asia, was introduced into the USA in 1876. Farmers in the South were encouraged to plant kudzu to reduce soil erosion. Once established in its new habitat kudzu can grow as fast as a foot a day!
Which of the following is likely NOT true about the impact of kudzu in the South?
a
Kudzu has the potential to overtake and replace native plants
b
Increase the biodiversity of the ecosystem in the South
c
Alter the nitrogen balance of the soil
d
Have long term impacts on the local organism populations
Answer:
hi what did you get for this one?
Explanation:
The statement which is not true about the impact of kudzu in the South is that it has long-term impacts on the local organism populations. Thus, the correct option for this question is D.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. It is generally an area or place where all the basic demands of an organism are fulfilled like food, space, mating partner, resources, etc.
According to the context of this question, the farmers in the south were encouraged to plant kudzu to reduce soil erosion. This means that it has the ability to increase the biodiversity of the ecosystem in the South.
Apart from this, it also has the potential to overtake and replace native plants. It also alters the nitrogen balance of the soil. But it does not express long-term impacts on the local organism populations.
Therefore, the statement which is not true about the impact of kudzu in the South is that it has long-term impacts on the local organism populations. Thus, the correct option for this question is D.

Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.
Answer:
One allows microbe to move in the medium and the other allows to see it.
Explanation:
Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.

As soon as the prey numbers dwindle and another species becomes more abundant, the predator will consume the more abundant species. In doing so, this predator maintains great biodiversity in the community. This type of predator is called a
Answer:
The correct answer is keystone predator.
Explanation:
In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.
