They carry an electric charge
The cells become differentiated and organised into groups or tissues
The volume and pressure inside the left ventricle at the end of diastole is referred to as end-diastolic volume and end-diastolic pressure respectively.
<h3>What is a diastole?</h3>
A diastole is the part of the heartbeat cycle when the heart muscle relaxes and allows the heart chambers to fill with blood.
The volume inside the left ventricle at the end of diastole is referred to as end-diastolic volume.
The pressure inside the left ventricle at the end of diastole is referred to as end-diastolic pressure.

<h2>(A) is the correct option </h2>
Explanation:
- Hydrothermal vents, also known as deep sea vents are the aftermath of a volcanic eruption due to shifting of the plates that form the Earth’s crust
- Black smokers are formed due to the high pressure at this depth and temperature of the trapped water because of which there is low oxygen content of water
- The black smokers emit fluids and causing it to emit chemicals such as sulfide, iron, copper and zinc
- Barophiles are organisms whose survival and reproduction is optimized to high pressures, such as those in deep sea environments
- Psychrophiles are microorganisms that can grow at 0 °C and below, have an optimum growth temperature close to 15 °C, and usually do not survive at temperatures above 20 °C
- They are found in permanently cold environments such as the deep waters of the oceans and because they are active at low temperature, psychrophiles are important decomposers in cold climates
Answer:
D) Beta galactosidase will not be produced.
Explanation:
Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.
Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.
