Answer: Oogenesis
Explanation:
Oogenesis is a process in female reproductive system in which a matured ovum is formed from egg cell.
In human reproductive system one mature ovum is produced from four haploid cells during meiosis. This ovum is very large and it unite with the sperm to produce zygote.
There are three stages of Oogenesis, the multiplication phase,the growth phase and maturation phase.
In the multiplication phase, the germinal cells divide to form oogonia. The oogonia multiply and form oocytes. The oocytes pass through the growth phase and mature to form ovum.
The waiter tears the raised part
of the straw wrapper a few inches from either end and he pulls until a piece of
the wrapper is entirely removed. The exposed part of the straw is what is then
placed in the drink, leaving the remaining wrapper for the customer to remove
himself. This will assure the customer that the waiter has not touched the straw
with bare hands. The part of the straw that has remained is called a straw
lace, or a drinking straw sleeve or a strawphylactic.
The answer is b. For example, nuclear fusion in the sun (an exergonic process) releases energy as light and heat, and powers the initial steps of photosynthesis (an endergonic process).
Answer:
D. Particle A orbits the nucleus, and Particle B is located in the nucleus
Explanation:
Here since both particles are of the same atom and particle A is much lighter we can infer that Particle A is electron because electrons are much lighter than protons which are Particle B in this case. Thus, particle A orbits nucleus as an electron does and particle B is in nucleus where protons are.
