<span>Watson and Crick determined the base pairing by using the new information to construct a new double-stranded helix model with the nitrogen bases paired A to T and C to G in the center. This base pairing immediately suggested to Crick that one side of the molecule could serve as a template to exactly replicate DNA sequences to pass on genetic information during cell reproduction. This second, successful model was unveiled in February 1951.</span>
Answer: Option D
Explanation: this depends on the food source and energy they utilize
Autotrophs are organisms that obtain their food source and energy by synthesizing these themselves using raw materials and energy (energy from the sun) they do this in the process known as photosynthesis obtaining energy from sunlight and they are also classified as autotrphs due to the presence of some components/features that will enable them to be able to synthesize their food for example, plants are autotrophs and they possess chloroplants: an organelle that contains chlorophyll that helps to channel the energy of sunlight into chemical energy and as well also gives plant their characteristic green color. They are also known as producers
Heterotrophs are organisms that rely on producers or other heterotrophs to obtain their food and energy. They either depends directly or indirectly on the producers for their energy source i.e. herbivores egg goats that feed directly on plants like grass; carnivores e.g lion that feeds on the herbivores this depending indirectly on plants.

C. Fat in adipose tissue</span>
Adipose tissue is known to be specialize organ that
primarily functions as a site of storage for fats inform of triglycerides. They
can also serve as an endocrine organ that is capable of synthesizing biological
compounds responsible for the regulation of metabolic homeoatasis.

Explanation:
these are right i know for a fact.. had this unit for school
Answer:
B
Explanation:
It's NAD+ because if you look at the electron transport chain, NADH delivers its electron to protein 1 (which causes NADH to turn to NAD+) and eventually those electrons move through multiple proteins to finally be accepted by Oxygen. If there's isn't oxygen, NADH won't be able to deliver electrons since those electrons wont end up anywhere. Which means NADH won't be oxidized (lose electrons) to turn into NAD+. NAD+ is necessary in citric acid cycle since it is reduced to turn into NADH.
