Changes in ecosystems are most pronounced when humans remove which species?
Answer:
Of course predators consume prey, but in doing so, they may have broader impacts on communities as a whole. That is to say, predators help to maintain a balance among organisms, both by consuming prey and by altering prey behavior and prey habitat selection. This article describes how predators influence the composition and distribution of species in communities.

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.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (in mg/mL) is quantified in two different lakes before and after an unusually hot summer. The coordinates of these four samples inR3are (i) Lake A: (97,84,43)and (100,80,50) before and after summer, respectively, and (ii) Lake B: (23,59,22) and (20,63,15)before and after summer, respectively.(a) How does the magnitude of the change in algal community compare between the two lakes
Answer:
Explanation:
Given that:
The abundance of three algal species in Lake A is now represented by the vectors:
[97, 84, 43] and [100, 80, 50]
Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:
a = [100 -97, 80 - 84. 50 - 43]
a = [3, -4, 7]
Thus, the magnitude of that change is:
[tex]|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}[/tex]
[tex]|a| = \sqrt{9+16+49}[/tex]
[tex]|a| = \sqrt{74}[/tex]
[tex]|a| =8.6 \ mg/mL[/tex]
The abundance of three algal species in Lake B is now represented by the vectors:
[25, 59, 22] and [20, 63, 15]
At Lake B, the change occurring in the vector of algae species can be determined as:
b = [20 -23, 63 - 59. 15 - 22]
b = [-3, -4, -7]
Thus, the magnitude of that change is:
[tex]|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}[/tex]
[tex]|b| = \sqrt{9+16+49}[/tex]
[tex]|b| = \sqrt{74}[/tex]
[tex]|b| =8.6 \ mg/mL[/tex]
Hence, for both Lake A and B, the magnitude of change is the same.

Research has found that chimpanzees in one area make spears to help them hunt bushbabies (African lorises). The chimpanzees locate a tree trunk in which the bushbabies live. They then select a tree branch, trim off the leaves and side branches, and trim the end of the branch to form a sharpened tip. The chimpanzees thrust these branches, like spears, into the tree to try to stab bushbabies (see the Lab 11 Exercise Image Library on p. 336 of your lab manual for associated images).
Is this behavior an example of nonhuman primate culture?
1. Yes
2. No
Primates often work together while hunting and then share the meat with others in the group.
1. True
2. False
Answer:
1. Yes
1. True
Explanation:
A.
Yes, it is a nonhuman primate cultural example: Despite the fact that many nonhuman primates lack apparent cultural traditions in the same manner that humans do, primatologists have uncovered a number of behavioral habits that differ between populations and are passed down through socialization and language interaction. The employment of tools by chimps for hunting is one of the most prominent examples of this. Chimpanzees in the African Savannah have been observed fashioning sticks into weapons to hunt bush infants, according to researchers. In each example, a chimp changes a branch by snapping off one or two ends and sharpening the stick with its teeth. The spear is then jabbed into the bottom of the trunk, where the bush infants slumber. Because this complicated behavior appears to differ between communities, it is thought that chimpanzee tool usage is socially acquired, and hence a cultural behavior.
B.
Chimpanzees hunt in groups so that they may corner their prey even if the canopy is continuous. Each chimpanzee within the hunting parties has a specific function to play during an arboreal hunt. Drivers are responsible for keeping the prey moving in a specific route and following them without trying to grab or catch them. Blockers are positioned at the base of the trees, climbing up to stop prey from fleeing in the other direction. Chasers move swiftly and attempt to capture the prey. Finally, when one monkey approaches, ambushers hide and flee. The food is delivered to all members of the hunting group once the animal has been trapped and slaughtered.

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
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.

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.

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.
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.

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.
