Answer:
Courtney is looking at Prokaryotic Cell.
Explanation:
Ok, when Courtney is observing the science experiment, and finds a cell that includes DNA and has a nucleoid region but does not have nucleus, it is a prokaryotic cell and only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes, where pro means before and kary means nucleus.
Let's explain what is a prokaryotic cell: prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. And most prokaryotes have a cell wall outside the plasma membrane.
Coral Bleaching is hazardous to fish because It leaves fish and corals vulnerable to deseases.And the average temperature of tropical oceans increases by 0.1 degrees C, over the past century.Fish are affected because, most fish in the ocean live in coral reffs, which end up dying, and leaving its habitant fish without a home.
Answer:
enrich the soil with nutrients
Explanation:
C and D are the answers. A is incorrect because of asexual reproduction. B is incorrect due to it have the same number. E is not correct because meiosis is sexual reproduction.
<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.
