Among the more important groups are the diatoms, cyanobacteria, dinoflagellates and coccolithophores.

Phytoplankton, are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis.

<h3>What are Phytoplankton ?</h3>

Phytoplankton is made of very tiny--usually one-celled--plants. Since plants make their own food and release oxygen as a byproduct, all the other living things in the ocean depend on them directly or indirectly for food or oxygen.

  • The two main classes of phytoplankton are dinoflagellates and diatoms.

  • Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells.

In the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
Gnesinka [82]

Answer:

The correct answer is : option B.

Explanation:

Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.

Hardy Weinberg equation is :

            P²+2pq+q² = 1

Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa)  as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).  

Thus, the correct answer is : option B.

What might the shape of the skull and the supraorbital height tell us about each species?
Sladkaya [172]

Answer: The shape of the skull and the supraorbital height tell us the following about each species-

  • It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
  • Most of the species possess similar skulls as mostly their structures are  oval shaped, sloped or round shaped.
  • Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
  • Variation in teeth and face shapes could also be due to different geological locations.
  • In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
  • Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
  • It also tells what probable causes of death would be when the species died.

if the earth did not have velocity horizontal to the pull of the sun‘s gravity what would happen and why
docker41 [41]

Answer:

The escape velocity of the Earth is about 11 km/s. In other words, anything on the Earth's leading side would fly off into space, continuing along the Earth's orbital path around the sun. ... Without the outward centripetal force to counteract the inward pull of gravity, the Earth would begin falling towards the sun.
