Explanation:

Equation for half-life of a first order reaction is as follows.

             t_{1/2} = \frac{0.693}{k}

where,        k = rate constant

Hence, it shows that there is no relation between temperature and half-life of a reaction.

Also, in second or third order reaction there is no relation between temperature and half life. As half-life is independent of temperature.

Thus, any increase or decrease in temperature is not going to affect the half-life time of a chemical.

Genrish500 [490]

Answer:

Position Effect

Explanation:

Position effect is referred to the effect on gene expression when the gene is translocated from the location it is on a chromosome to another location.

As it relates to gene silencing and euchromatic gene repositioning, Position effect variegation best explains it.

Position effect variegation occurs when a gene in some cells is silenced as a result  of rearrangement of chromosomes which translocate or reposition euchromatic genes close to vicinity of heterochomatin. It is this abnormal chromosomal juxtaposition that leads to the gene silencing in stochastic pattern.

E. coli cells grown on 15N medium are transferred to 14N medium and allowed to grow for two more generations (two rounds of DNA
White raven [17]

Answer:

Option (d).

Explanation:

DNA is the genetic material of all the organism except some viruses. DNA is composed of nitrogenous base, deoxyribose pentose sugar and the phosphate group.

DNA replicatese by semi-conservative mode of replication in which one the daughter DNA consists of one newly synthesized strand and one parental strand. This mode of replication was explained by Messelson and Sthal experiment. The cells from 15N medium are transferred to 14N medium the band of intermediate density was observed. The daughter DNA consists of one 15N DNA strand and one 14N DNA strnd. This strand undergo replication in the 14N medium. This time one low density DNA band ( contains 14N - 14N DNA strand) and one intermediate density band ( 14N-15N DNA).

Thus, the correct answer is option (d).

Assoli18 [71]

Answer:

It will increase the rate of photosynthesis as there will be more carbon dioxide ... however there may be a limiting factor which will limit the rate to keep it constant... Such as the opening if the stomata to receive more CO2 which in turn causes loss of water by transpiration.
