An Egg Develops Without Being Fertilized By A Sperm.
Answer:
C. Properties that can change the chemical nature of matter.
Explanation:
Chemical properties is a characteristic of a chemical substance observed when it undergoes a chemical reaction on seeing its precipitation. On knowing the chemical properties of a substance it aids in separation, purification and classification of a compound. some examples of chemical properties are as follows:
1. Toxicity
2. Inflammability
3. Reaction with other chemicals
4. Oxidation
Plasma membrane is the structure which covers up the uptaken molecule.
<h3><u>Explanation:</u></h3>
Uptaking of nutrients from the surrounding needs to be very appropriate for the cell to obtain nutrition, as well as to maintain cell immunity. In case of simpler molecules like glucose etc, the molecules are taken inside the cell by means of specific channels or transport proteins. In case of complex molecules, cells prefer to perform endocytosis - either phagocytosis for solid ones, and pinocytosis for liquid ones.
When the cell finds something which can be taken in, it projects a fold of cell membrane towards the liquid which surrounds part of the liquid, or fully. This cell membrane then presents a depression which covers up the liquid. Then the margins of the depression come closer and ultimately fuse, leaving the liquid inside the cell enclosed with a part of cell membrane. This then fuses with a primary lysozome to form a digestive vacoule, a secondary lysozome, a residual body, and ultimately gets excreted off the cell.
Answer: 1) DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms ( that is passed from parents to next generation). It determines the structure of protein that carry out essential function of life.
- For this, DNA possesses instructions in the form of specific nucleotide sequences. First it undergoes transcription, in which genetic information from DNA is passed to mRNA ( messenger RNA), which is finally converted to specific protein through translation.
2) The importance of DNA determining proteins is that the proteins, which are formed, corresponds to specific cellular activities ( such as digestion of proteins, fats, carbohydrates) as well as the characteristics/ traits ( like color of skin, color of eyes) of the organism.
In this way, traits are passed from parents to their offspring through genetic material.
