Answer:
95 isoadenine bases; adenine bases cannot be determined
Explanation:
In Alien DNA;
- iA complementary with U
- iT complementary with A
- bG complementary with iC
- So if there were 95 nucleotide that contain the uracil then there should also be 95 isoadenine.
- Adenine binds with isothymine in alien DNA and there are no information of isothymine or other bG/iC bases is given, so we cannot determine the adenine bases.
False. Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat.
Lancelet is a chordate but not a vertebrate because it lacks a backbone
Explanation:
The subphyla of the phylum Chordata are - Vertebrata, Urochordata and cephalochordate
Those chordates with a structural backbone belong to Vertebrata.
Urochordates and cephalochordates lack a backbone and hence are termed invertebrate chordates.
Lancelet is an invertebrate chordate of the subphylum – Cephalochordata.
The lancelets consist of a notochord that extends right from the head till the tail at the dorsal surface. The notochord acts like the backbone and provides support and a semi-flexible structure to aid in the movement of the organism.
They lack a developed nervous system like vertebrates but only has a dorsal nerve tube

Answer:
A should be the correct answer.
The correct answer would be letter B: water molecules split into oxygen and hydrogen atoms. This is how plants convert water into a usable source of food and energy to support its photosynthetic capacity to power the plant within its environment.
