Answer:
Different species within a phylum all have the same basic characters, anatomical and functional integrity, common ancestry.
Explanation:
The animals having same phylum but different species have similar basic structural pattern. That means the anatomical features are constructed on the same ground plan. This individuals have similar functional integration. All animals of a phylum work as a functional machines with similar functional integration.
Another important feature is they have common ancestry. Evolutionary study have confirmed all members of a similar phylum have been derived directly or indirectly from a common primitive ancestry.
Answer:
It allows ice to float to the top of water, insulating water below allowing life to live. It allows ice to sink to the bottom of water, allowing life to live above
Explanation:
Answer:
No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.
Explanation:
Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.
When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.
