The correct answer is - B. feathered.
The primitive mammals were very small (with a couple of exceptions), rodent-like, also very often described as shrew-like. They were feeding with plants, as well as with insects and the occasional egg. Most of them were night creatures, and they were living in the shadow of the much bigger dinosaurs.
So, they were small, furry, rodent-like, night-dwellers, but there isn't a single evidence that any of the primitive mammals, or any mammal whatsoever, had feathers.
Answer:
A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.
Explanation:
- A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
- A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
- A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
- A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
- A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.
Answer: Food consumption and production have a considerable impact on the environment. Food production contributes
Explanation: , for example, to climate change, eutrophication and acid rain, as well as the depletion of biodiversity. It is also a considerable drain on other resources, such as nutrients, land area, energy, and water.
