Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by
x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>
= 10 generations
<u>New bacterial population</u>
Using formula<u> </u>
x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
Answer:
olecules can diffuse across membranes via transport proteins, or they can be aided in active transport by other proteins. Organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria and peroxisomes all play a role in membrane transport.
Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.
Answer:
I think its true ..... ...
1. I think natural selections among the animals are base on their ways or their role in the food chain whether they are predator or a prey. Natural selection is the one you will judge if you are gonna leave or die but it doeasnt mean that here is no way of survival. I think there role in the chain mold them and taught them on how to survive in the wild.
2. The best example of it is when and infant started to grow, so an infant baby's center of sensation is their mouth, if they don't like the taste of it they throw it away until the developments are on the process, they begin to walk then to speak.
3.The behavior of an animal like for example the wolves, they use to be in pact to hunts prey so that they could sure the possible outcome in hunting base on that fact, if a wolf will hunt for its self in a group and fast running dears without a plan the possibility is that the wolf will never catch one
