An opportunistic predator switches prey, capturing whichever prey species is most abundant. 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

Answers

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.

Describe the kind of transport the paramecium uses to remove water from its cytoplasm. (1 point) b.

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)

Answers

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.

The diagram below shows two locations where fossils of Mesosaurus have been found. Mesosaurus was a fresh water reptile that existed on Earth about 250 million years ago. Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?

Answers

Answer:

they was together at one point but because of the plants under the Continent they were separated and moved

Answer:

The statement which best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa is The remains of the Mesosaurus were carried across by predators.

Where have Mesosaurus fossils been found?

Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.

How do we know Mesosaurus was freshwater?

For years, mesosaurs have been considered aquatic (water-living) animals, because they have several characteristics of species that are adapted to aquatic life, like webbed hands and feet and the presence of thickened and compact bones.

Answers

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.

Explanation:

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.

Answers

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.

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.

Answers

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.
