G1 is the most important phase of meiosis or mitosis.It is the phase when the first cell growth happens.If G1 never happens,the cell aren't mature and DNA chromosomes won't be condensed.The next phase,S phase,take the DNA and copies them.If the DNA never got condensed and mature in G1 phase,S phase wouldn't be accurately completed and then this could result in mutations,and etc.
Hope this helps:)<span />
Answer: An operon is described as a functioning unit of DNA that possesses cluster of genes, which are present under the control of single promoter. This means that all the genes of operon are transcribed at the same time to form a single polycistronic mRNA strand that codes for multiple proteins.
- An operon primarily consists of operator ( to which repressor protein binds, which is produced by regulatory gene and inhibits the expression of structural genes).
- promoter ( to which RNA polymerase binds and initiates transcription).
- structural genes/genes of an operon that are present downstream of promoter and are transcribed and translated to produce proteins.
Inducer is a protein molecule, binds to regulatory protein and brings change in its conformation so that it can no longer bind to an operator, thus switching on the operon.
Thus, the correct answer for blanks is-
1) operon
2) genes of an operon
3) promoter
4) regulatory gene
5) operator
6) repressor
7) inducer
The question is incomplete as the image and options are not given, however, the correct image and options are as follows:
A. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will increase.
B. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will decrease.
C. When the temperature of gaseous Material A increases, its volume will increase.
D. When the temperature of liquid Material A increases, its volume will increase.
Answer:
The correct answer is - C. When the temperature of gaseous Material A increases, its volume will increase.
Explanation:
The figure and table related to the given question are attached with the answer that shows the volume change during the time period in relation to temperature and the phase of material also changes with an increase in temperature.
According to Figure 1, it is clear that initially, Material A was in the liquid phase and after a certain temperature, it is constant at a phase of a mix of liquid-gas and finally entirely in the gas phase from Time 22 sec to Time 24 sec. as temperature increased and the volume of Material A also increased according to the table 1.
So the hypothesis C is correct.
Other limiting factors of plants are the amount of sunlight and the type of soil. Animals also are limited by conditions in the environment. Even though owls do not eat plants, the number of owls is affected by the number of plants. Limiting factors of animals include temperature, water, food supply, and shelter.
