Generally all living organisms do have cell membranes, except viruses (this is still a controversial topic). I hope this helps :)
These are spores, which are produced by bacteria and are involved in survival or reproduction. Some different types include endospores, which are heat-resistant spores formed within the cell, cysts, which are dormant cells sometimes enclosed in a sheath, arthrospores, which are produced by different bacteria as part their reproductive cycles and myxospores, which are formed within a fruiting body.
Answer:
The most appropriate answer would be option 2.
In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.
Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.
Answer:
Option-1 and 4
Explanation:
Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.
The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.
The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.
Thus, in the given question option-1 and 4 show, this adaptation and are true options.
