Answer:

D

Explanation:

The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.

According to the cell theory which is made up of three parts;

  • <em>The cell represents the basic unit of all life.</em>
  • <em>All living organisms are made up of cells.</em>
  • <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>

Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.

The correct option is, therefore, D.

Which statement describes the relationship between the lizard and the frog on the food web?
Snezhnost [94]

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>

If there are class B mutations in the flower development genes of Arabidopsis thaliana, then determine the structures present in
kotegsom [21]

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

How might an individual's own cells lead to false verdicts of guilt.
Gre4nikov [31]

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.
