B. Phosphate group, since ATP includes phosphate
Answer:
Zooplankton -tiny aquatic habitat organisms- gets their energy from phytoplankton consumption.
Explanation:
Zooplankton, or animal plankton, is characterized by being heterophosphoric organisms, obtaining its energy by consuming organic matter.
The main food source of zooplankton is phytoplankton, although they can also feed on organic waste, from the same zooplankton or even bacteria.
Zooplankton is composed of a very small fauna that includes single-cell organisms -such as protozoa and protists- fingerlings, larval forms of mollusks, crustaceans and aquatic arthropods.

Answer 1)
Not 2 bc they don’t come from the soil, they are made by plants through photosynthesis.
Not 3 bc I’m pretty sure sugar is not the only source of food for plants.
Not 4, I’m not exactly sure why not 4, but my gut is saying 1.
Sorry the explanation is not super helpful.
Here are some key features of DNA polymerases:<span>They can only add nucleotides to the 3 end of a DNA strandThey can't start making a DNA chain from scratch but require a pre-existing chain or short stretch of nucleotides called a primerThey check their work, removing the vast majority of "wrong" nucleotides that are accidentally added to the chain</span>
Answer:
Parent 1 : AaBb
Parent 2: aaBb or Aabb
Explanation:
In this cross two genes are involved and they are duplicate genes with cumulative effect i.e. individually they show the same phenotype but when together, they produce a new phenotype. Here,
A_B_ = red
aaB_ = sandy
A_bb = sandy
aabb = white
The progeny in question has a white piglet (aabb) so it must have got a set of "ab" gametes from both parents. Since parent 1 has red phenotype it should also have one A and B allele. Hence its genotype is AaBb.
Parent 2 should also contribute an "ab" pair to white piglet and it has sandy colour which is produced by either an A allele or a B allele so its genotype should be Aabb or aaBb.
