Answer:
: Green Plants are the sources of energy for all oraganism. They trap the solar energy and convert it into chemical energy in the form of food(starch)and they give off oxygen. if all green plants would not be there then all the herbivores will die due to starvation and so will the carnivores.
:Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe.
Also many plants are very useful in field medicine.
:Roots of plants and trees reduce soil erosion by holding the soil firmly.
Answer:
It is either the epiglottis or larynx
Explanation:
Answer:
meiosis_
fertilization
mitosis
zygote
Explanation:
In life cycles that alternate between haploid and diploid stages, ____meiosis_ acts to reduce the number of chromosomes per cell from two sets to one set. In life cycles that alternate between haploid and diploid stages, ___fertilization__ acts to double the number of chromosome per cell from one set to two sets. In life cycles that alternate between haploid and diploid stages, ______mitosis______ acts to keep the number of chromosomes per cell the same. In animals, a single diploid cell called a ____zygote________ divides by mitosis to give rise to all the cells of the adult body.
Answer:
<h2>
Haploid=13</h2><h2>
triploid=39 </h2><h2>
tetraploid=52</h2><h2>
trisomic=14 </h2><h2>
monosomic=12</h2>
Explanation:
Given;
A species with a diploid number of 26, so 26= 2n ( a diploid cell),
so in haploid condition, chromosome number becomes half (13 in this case). triplod is when 2n + n, and 2n +2n ( tetploid). Trisomy and monosomy is the addition or deletion of a sinlge chromosome of a sinlge set .
Haploid=13, one chromosome from each pair of chromosome set,
triploid=39 (13× 3); diploid+ n( 3n)
tetraploid=52 (13× 4) 4n
trisomic=14 (13+1) ; n+1
monosomic=12 (13-1); n-1
There are 15 students in math class.at the begning of class everyone races into class as everyone love maths.the professor takes note of the first 5 students who gets class and ranks them according to the order in which they entred as their top 5 favourite students. in how many different ways could the professor rank their top 5 students using formulla from combinations and permutations
