Which of the following most correctly represents biomanipulation through the top-down model?
Addition of quaternary consumers, so that tertiary consumers can decrease
Removal of tertiary consumers, so that secondary consumers can increase
Addition of primary producers, so that secondary consumers can increase
Removal of secondary consumers, so that tertiary consumers can increase
Answers
Answer:
B. Removal of tertiary consumers, so that secondary consumers can increase.
Explanation:
Removal of tertiary consumers leads to the increase in the population of secondary consumers because tertiary consumers feeds on the secondary consumers. If the population of predators decreases, the population of prey ultimately increases in that ecosystem. Biomanipulation is the change of an ecosystem by adding or removing species, that feeds on other animals such as predators so we can say that removal of tertiary consumers leads to the increase in the population of secondary consumers.

1. What controls each mechanism? 2. What detects a disturbance in the body’s condition? 3. What corrects the change?
B. What is a negative feedback mechanism, non living example.
Answers
Answer:
Homeostatic control mechanisms have at least three interdependent components: a receptor, integrating center, and effector. ... The integrating center, generally a region of the brain called the hypothalamus, signals an effector (e.g. muscles or an organ ) to respond to the stimuli.
Explanation:
In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answers
Answer:
The small population of zooplankton have an unequal effect on the marine community.
Explanation:
According to this question, there are three trophic levels of organism in a lake as follows: non-native fish, zooplankton, and algae. However, due to the declination in the number of zooplanktons in the lake as they were fed on by the non-native fish, the algal population increased to form a BLOOM.
This bloom of algal species can be attributed to the lack of zooplanktons, which represented the only herbivorous (plant eaters) organism in that community. Hence, their relatively small population have an unequal effect on the marine community. This means that the small population of zooplanktons caused an imbalance in the community and this is why ZOOPLANKTON is the keystone species in this scenario.

How does the body make these different cells?
Answers
Answer:
Body tissues expand as the amount of cells that make them up increases. When cells are destroyed or die, the body replaces them with new cells. Cell division is the name for this operation. One cell divides into two, doubling its size.

In the Galapagos Islands, there were many species of tortoises, woodpeckers and other animals. Why were the animals like the tortoises so different in appearances, when they lived on neighbor islands?
Answers
Answer:
The animals were different because there were things the animals need to adapt to in the Galapagos that may have changed their appearance. for example a bird may have a different shaped beak because they started to evolve so they could eat foods that were available to them on the island

the population would increase
Explanation:
lets say your population is x,
if you keep increasing it,
x+++++,
it gets larger.
(eventually it may run out of resources and decrease in size, and then increase in size, which we know from observing the population of species in the world around us [and by logically assessing what available resources indicate])

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the
male minnows all had a moderate number of spots
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were
better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female
minnows in this pond preferred to mate with males that had the most spots,
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
Answers
Answer:
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.
