-2m<5k+10-18d-9k
-2m<-4k-18d+10
-m<2(-2k-9d+5)/2
-m<-2k-9d+5
m>2k+9d-5 (when divided by -1 the inequality changes)

Answer:

Option (c) is correct.

m > 2k - 5 + 9d

Explanation:

Given : 18d – 2m + 9k < 5k + 10

We have to solve for m.

Consider the given 18d – 2m + 9k < 5k + 10

Subtract 9k both side, we have,

18d – 2m + 9k - 9k < 5k + 10 - 9k

Simplify, we have,

18d – 2m < -4k + 10

Again subtract 18d both side, we have,

18d – 2m - 18d < -4k + 10 -18d

Simplify, we have,

– 2m < -4k + 10 -18d

Multiply both side by -1 and this reverse the inequality, we have,

2m > 4k - 10 + 18d

Divide both side by 2 , we have,

m > 2k - 5 + 9d

Thus, Option (c) is correct.

The temperate phage lambda can undergo two life cycles depending on the environmental cues. During which cycle does phage lambda

Akimi4 [234]

Answer:

<h2> A. lysogeny</h2>

Explanation:

Lamda phase can undergo two types of life cycle i) lytic and ii) lysogeny depemding on situation.

Lysogeny life cycle: In lysogeny life cycle, phase insert its DNA into the bacterial DNA , this inserted DNA is known as prophage. This can be remains in the form of prophage for a very long period, or in the stress conditions, prophage can become virulent and removed himself from the bacterial DNA. After this, bacteria can undergo lytic cycle and produce many phase particles.

Late successional plants are largely unaffected by plants at earlier stages of succession because they are not in direct competi

kari74 [83]

Answer:

Tolerance.

Explanation:

Ecological succession may be defined as the change of an species, its structure and change in the ecological community with time. Two main types of succession are primary succession and secondary succession.

The earlier plant stage does not affect the late successional plant stages. These two plant stages does not have direct competition, they are showing the tolerance model. The different species tolerate the different successional stages of each other.
