Question

oxygen is necessary for germination of seeds ​

Answer 1

Answer:

Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores. Like all organisms, this is done through a process known as aerobic respiration. —a series of reactions where energy is released from glucose, using oxygen.

Answer 2

Answer:

is given that BE = CF

(i) In ΔABE and ΔACF,

A = A (It is the common angle)

AEB = AFC (They are right angles)

BE = CF (Given in the question)

∴ ΔABE ΔACF by AAS congruency condition.

(ii) AB = AC by CPCT and so, ABC is an isosceles triangle.
