Heat given off by the sun would give the cell energy aswell as the nutrients therefore the rate of cell division would be higher. the prediction could be tested by putting algae I'm both the places and recording the rate of cell division
The weathering of silicate rocks exposed by up lift due to orgeny and subduction of ocean sediment and they also are the formation of shells by marine organism.This is the correct awnser.
<h2>Droughts kills many trees</h2>
Explanation:
- The example of Droughts kills many trees do not involve the flow of information providing feedback.
- Drought is a condition when there is a prolonged shortage of water.
- The duration of drought can be for a month, year or more than a year.
- The drought is caused due to the human activities such as Deforestation.
- Due to less rainfall in a region also causes the Drought in an area.
Answer: The lac operon is an inducible operon that is activated in the presence of lactose.
An operon is a unit of genes which are controlled by the single promoter and operator sequence. It consists of a regulatory gene, promoter, operator, and structural genes.
Lac (lactose) operon consists of three structural genes namely lacZ, lacY, and lacA. These genes are transcribed and translated to produce specific enzymes used for lactose metabolism.
It is called as inducible operon because lactose acts like an inducer as its presence induces the transcription process. The lactose is first converted into allolactose which then binds to repressor (synthesized by regulatory gene). In this way, it makes the repressor inactive and therefore allows the transcription of structural genes.
Answer:
(1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which new minerals form at the expense of earlier ones owing to the effects of changing—usually increasing—temperature or pressure or both on some existing rock type, and (4) hydrothermal, in which minerals are chemically precipitated from hot solutions within Earth.
