Answer:
Option-C
Explanation:
In gymnosperms, the embryo is formed after the fertilization needs nutrition. The nutrition in the gymnosperms is provided by the female gametophyte cells as these cells degrade to provide the nutrients. Since the female gametophyte is haploid in nature, therefore, is the correct answer.
The seed is formed after the fertilization has occurred therefore is considered the diploid structure. The outer structure which helps in the dispersal of the cell thus is considered the diploid structure.
Thus, Option-C is correct.
Answer:
Mosses or lichens.
Explanation:
Mosses or lichens are the group of species have great impact on the long term dynamics of succession if they develop resistance against fire events because these species can used the ashes of other plants as a nutrients for their growth and development. These group of species spread at a higher rate which covers most of the area of the forest and become a dominant species in the forest. Due to the presence of these species, the organisms who feed on these species comes to these forest and slowly the diversity of the forest is attained.
The probability that neither of them is a heavy smoker is 0.53 or 53%
<h3>What is genetic probability?</h3>
Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.
In this case:
Probability that selected one is heavy smoker is:
p=270/1000=0.27
Number of individuals selected is 2 and We know that:
P(X=x)=nc_x(1-p)^{n-x}(p)^x
We need to prove that X=0:
P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0
P=0.5329

First of all you have to make both sides of the equation equal
KClO3 -------- KCL + O2
this is the way i would do it first
K - 1 K - 1
Cl - 1 Cl - 1
O - 3 O-2 From this we can see that the oxygen of both don't equal
So than from this we would need to find the common factor of the oxygen which is 6. So we would multiply 3 by 2 to get 6 as well as 2 by 3 to get 6.
The equation will now look like
K - 1 K - 1
Cl - 1 Cl - 1
O - 3 (2) = 6 O - 2 (3) = 6
so the final answere:
KCl2O3 --------- KCl + 3O2
