Answer:
answer is d
The reproductive cells of an organism also called the sex cells in either male or female undergo the process of meiosis to reduce the diploid number into a haploid number ie reduction into half the original number.
This is to ensure that during reproduction, with the coming together of haploid sex cells (both haploid sperm and the haploid egg cell). A diploid organism can be produced.
If a hypothesis is stated and outcome of the experiment is what was predicted, then it supports the hypothesis. if the experiment does not support the hypothesis, then the outcome was not what was predicted.
Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy = 
× m × v²
Applying the formula:
Kinetic energy = × 5 × 7²
⇒ × 5 × 7 × 7
⇒ 
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
When a female animal and a male see each other the male would show off and they woulf matr and make a baby then the babys will grow up and make more
Answer:
Equation of reaction:
a) 2HCl + Ba(OH)2 ==> CaCl2 + 2H2O
b) Molarity of base = 0.042 M.
Explanation:
Using titration equation
CAVA/CBVB = NA/NB
Where NA is the number of mole of acid = 2
NB is the number of mole of base = 1
CA is the molarity of acid =0.15M
CB is the molarity of base = to be calculated
VA is the volume of acid = 25 ml
VB is the volume of base = 44.45mL
Substituting
0.15×25/CB×44.45 = 2/1
Therefore CB =0.15×25×1/44.45×2
CB = 0.042 M.
