<u>Answer:</u>
Part of a strand of DNA with regulatory sequences is Lac gene.
<u>Explanation:</u>
- Genes are the part of DNA that helps in development of traits of individual and helps in inheriting characteristics to offspring.
- In Lac gene(operon, which is fundamental unit of DNA) gene regulation (first genetic regulatory mechanism) was clearly observed for the first time.
- Lac gene is a gene that is required for the 'breakdown of lactose' and also helps in transporting of it.
- There are types of lac genes differing in structure are: LacA, LacY, LacZ.
<span>One group is given a larger dosage than is typically prescribed.
A second group is given a smaller dosage than is typically prescribed
Then results of the groups are compared to each other.
The thing that is missing in this experimental design is a third group who are tested with the typical dosage.</span>
Answer:
This question is incomplete, the complete question is: When a cell needs energy, I take in nutrients break them down, and supply energy to the cell. I can also convert stored energy in the cell to food. I am a?
The answer is MITOCHONDRION
Explanation:
All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.
However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.
Answer:
Papillary Layer
Explanation:
In addition, the papillary layer contains phagocytes, defensive cells that help fight bacteria or other infections that have breached the skin. This layer also contains lymphatic capillaries, nerve fibers, and touch receptors called the Meissner corpuscles.
