Answer:
The prokaryotes uses organ called Pilus during conjugation process.
Explanation:
Pilus is a long thread like appendages which seen in the capsules of the bacteria. During conjugation process, the pilus from the donor bacteria extends and gets attached to the recipient bacteria.
The shared pilus acts as the bridge between the donor as well as the recipient bacteria through which the exchange of genetic information occurs. Thus it can be inferred that during conjugation prokaryotes uses pilus.
Question: Which describes the variable that is changed to test the prediction?
A)dependent
B)experimental
C)control
D)independent
Answer: The variable that describes the changed to test the prediction is "independent."
Explanation:
The independent variable is the factor which gets changed or can be controlled to see its effect over the experiment. Only the independent variable responds to the changes. The independent variable will be shown on the x- axis. The age and time are two different independent variable. These two factors are independent of everything else. The variable which can be easily manipulated during the experiment is called as the independent variable.
Answer:
The annual precipitation varies most in tropical rain forest ecosystem.
Explanation:
Tropical rain forest is one of the most extensive selvatic ecosystems, with a very dense vegetation, which is characterized by its high temperatures and abundant and varied annual precipitations, which are between 1500 and 5000 mm per year.
This ecosystem can be found in Central America, Mexico, Australia and even in Asia, where a seasonal climate can be seen divided into rainy seasons -which register the highest rainfall- and a dry season, where rainfall is lower. Most of the year the climate is hot and one of its characteristics is to present the greatest variety of animal and vegetable species.
