damaskus [11]

Answer:

True

Explanation:

In biology or animal behavior, the term cuckold refers to the act of invading a strange net. The term might be applied to different species that parasite other species. A very well known example is the cuckoos bird.

The Cuckold bees or cuckoo bees are many parasitic species belonging to the Apoidea taxon that characterize for invading nests of other bees.

Females lay their eggs in the cells of the host nest. Depending on the species, the intruding female might kill the owner larvae of the cell, or the emerging parasitic larvae is the one that can destroy the host using their highly developed mandibles as weapons.

As they develope, foreign larvae feed on the foodstuffs that the female owners of the nests bring for their own offspring.

Leak channels and sodium-potassium pumps are present on the cell body, dendrites, axon and terminal ends of the neuron cell memb
notka56 [123]

Answer: True

Explanation:

The neuron has leak channels in the cell body, axon and dendrite and cell body. This is because the trans membrane potential exists in all parts of the cell membrane.

Because of this reason the the leak channels are available at each part of the neuron.

The action potential, trans membrane potential should exits in all the parts of the cell so it should be located in all the parts of cell.

  • (C) The public project used a mapping strategy to limit the total sequencing required
  • (D) The Celera group, led by Craig Venter, used a shot gun sequencing strategy

Explanation:

  • As the project was unable to sequence all the DNA that was found in the human cells, the first draft was <u>made in June and complete in the end referred to as a working draft and made on the basis of the final sequencing and mapping of the human genome. </u>
  • The <u>draft included the alternative strategies for the completion of the bottom up and top up of the genome code and has a mapping strategy</u> that limited the total sequencing needs.
