Cells reproduce for 3 reasons- to make new kinds of cells (gametes or more specialized cell types), for repair, and for growth. IF IT HELP YOU PLZ PICK AS BESTT!!!!
One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope
These are known as centrioles, which are microtubule organizing centers
Describe the effects of man on the ecosystem with emphasis on examples of international importance (tropical rainforests)
Human activities have adversely affected the ecosystem because human needs wood for making houses so they cut the trees and the organisms lives there loss their habitat and whole ecosystem is disturbed. Tropical forest is also called lungs of planet earth because they provide oxygen to the atmosphere and absorbs carbondioxide gas in large amounts. About half of world species lives in these forest. If humans continue to cut these forest all the species lives their will be vanished and affected the whole world.
What should you avoid doing before opening a birds cage
you should avoid having any doors or Windows open
also give them a little space so they don't fly in the whole house like a small room
You should avoid any doors or windows open do that the bird won’t escape and and not to anger the bird whilst opening
A few hundred red deer were introduced, in 1998, into a prairie ecosystem where they faced no natural predators. The graph shows the subsequent variation of the deer population in a certain area of the prairie. Explain, using the concept of carrying capacity, the observed variation of the deer population over time.
The carrying capacity is the maximum size of some population. It represents the number of animals that can live, reproduce, survive in the given area regarding the indefinite sustainability of this area in terms of resources (food, water, habitat, etc.). When animals are introduced into some area, the resources are abundant. But, as the number of animals in the population grows, the resources reduces. Once the population reaches the carrying capacity the growth of population will stop (on the graph in the year 2002). With reduced resources, the competition for resources will increase, and also, animals are more prone to predators and diseases. All of this will decrease population size for a bit (on the graph year 2003).
What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?A. –5 m/s^2
B. +5 m/s^2
C. –25 m/s^2
D. +25 m/s^2
In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question. Initial velocity = 25 m/s Final velocity = 0 m/s Initial time = 0 second Final time = 5 second Now we can write an equation to determine the acceleration. Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time) = (0 - 25)/ (5 - 0) = - 25/5 = -5 m/s^2 So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".
