Answer:
The correct answer would be D) Kittens receive features from both parents but the plant offspring receives features from a single parent.
Cat only reproduces sexually in which male and female parent contribute equal genetic material to the offspring. It leads to the genetic variation in the offspring.
In addition, crossing over takes place during gametogenesis also adds to the genetic variation of the offspring produced by sexual reproduction.
This is the reason that kitten (offspring produced by sexual reproduction) has some genetic variations as compared to the parent and it does not resemble either of the parents.
In contrast, saplings can be done vegetatively through cutting due to saplings receive genetic material from a single parent.

Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.
Answer:
It destroy both harmful and beneficial microbes.
Explanation:
If scientist added a chemical to destroy the arctic microbes, the beneficial as well as harmful microbes also eliminated from that area where chemical is applied. The removal of harmful microbes is a good thing but the removal of beneficial microbes brings instability in the environment. These beneficial microbes helps in the recycling of nutrients for the plants present there. So the negative effect of chemical is that it also effect the beneficial microbes which are necessary for the ecosystem.
