Answer;
The amount of water and the temperature of the water and the angle the bottle was set in.
Explanation;
The two main variables in an experiment are the independent and dependent variable;
-An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example; the dependent variable in tornado in a bottle is the amount of water and the temperature of the water and the angle the bottle was set in.
Answer and Explanation:
The pectorals major is an enormous, fan-formed muscle covering the chest. It is included clavicular and sternocostal areas. Adducts and turns the upper arm. Transverse adduction and flexion of the pectoralis major is smooth movement. You can see the muscles extending far and contracting back effectively.
The biceps brachii is a two-headed muscle. Despite the fact that most of the bulk is found anteriorly to the humerus, it has no connection deep down itself. The activity is Supination of the lower arm. It likewise flexes the arm at the elbow and at the shoulder. In the biceps brachil there isn't a lot of expansion found in the muscle contrasted with the pectoralis major.
Answer: The right answer is -
A) Gene flow
Explanation:
Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.
As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.
Thus, option A) is the right answer.
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
