The stem of the plant should be cut at least three to four centimeters above the surface level.
The stem should be tightly fixed into the glass capillary.
All connection should be made air-tight by using paraffin.
Initial and final readings should be carefully noted.
Answer:
Answer is 512 nucleosomes.
Explanation:
<h2>The correct option is (A) and (B)
</h2>
Explanation:
- Lipids are fundamentally and practically various groups of hydrocarbons. Hydrocarbons are the substance chemical in nature and comprise of carbon and hydrogen atoms. The carbon-carbon and carbon-hydrogen bonds are nonpolar, which implies that the electrons between the molecules are shared similarly. The individual nonpolar bonds grant a general nonpolar characteristics to the hydrocarbon compound.
- The naturally significant classes of lipids are fats, phospholipids, and steroids.
- Carbohydrates are one of three essential macronutrients expected to support life (the other two are proteins and fats). They are found in a wide scope of nourishments that bring an assortment of other significant supplements to the eating routine, for example, nutrients and minerals, phytochemicals, cell reinforcements, and dietary fiber. Organic products, vegetables, grain nourishments, and numerous dairy items normally contain starches in different amounts, including sugars, which are a sort of starch that can add taste advance to a nutritious eating routine.
Multi cellular colonies of plant cells adhere to each other primarily by cell walls, whereas multi cellular colonies of animal cells are typically held together by proteins
<h3><u>
Explanation:</u></h3>
The organisms that contains more than single single are called as multi cellular organisms. They are just opposite to the uni cellular organisms. When many identical organisms groups to form together it is called as colonies.
It will be difficult in removing any organisms that forms colonies with the multi cellular organisms.The multi cellular organism of the cells in the plants are bonded to each other with the help of the cells walls. In animal cells these are bounded together with the help of the proteins.
All of these models apply to the scenario equally well.
Explanation:
- Firstly, the male crabs battle each other for territory using their greatly enlarged claws. This clearly depicts male-male competition.
- Secondly, Females choose to mate with only those male who are fit to survive in stress full condition. Thus female look for good genes that would enable her offspring to survive in stressful condition. Here Good gene mechanism applies.
- Thirdly, The presence of large claws make it more noticiable to female and stronger to compete with other males. Thus this is a direct benefit.
- Lastly, we see that female crab have a tendency to look up for their prey and this tendency is well exploited by male crabs who raise their claws to a heigh so that they get noticed by the female.
