Answer: A.) Heterotrophs compete for the same food source.
A food chain is a linear sequence in which food and energy is being transfered when one organism is fed the another organism in an ecosystem. A food web is a interconnection of two or more food chains. Heterotrophs are organisms which are dependent upon other organisms for the food requirement. In the given condition, the lizard and frogs are the heterotrophs which are dependent upon insects for their food requirement.
<em>Hence, heterotrophs compete for the same food source is the correct statement to describe the relationship between the lizard and the frog on the food web. </em>
Answer:
Whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Explanation:
ABC model of flower explains the role of various genes in the formation of a flower from the shoot. Each gene forms a particular structure of a flower in the following manner:
1. A gene -sepals. (Whorl-1)
2. A + B- Petals (Whorl-2)
3. B+ C - stamens (Whorl-3)
4. C- carpels. (Whorl-4)
If a flower lacks the B gene, the effect will be observed in the phenotype in which B gene is involved that is in the formation of petals and stamens or whorl 2 and whorl 3.
The flower will produce
whorl-1- petals
Whorl-2- petals (mutant)
Whorl-3- carpels (mutant)
Whorl-4- carpels
Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.
Answer:
The answer is Make reclamation required after mining operations have ended
Explanation:
If a company has removed the minerals out of the mining place, mined areas must go through reclamation, which returns land to a usable state after mining operations have ceased.
Answer:
The <u>genotype </u>is the internal hereditary code that tells which <u>phenotype</u> will be expressed.
