Which of the following organelles is the principal and distinquishing feature of the eukaryotic cell? A. ribosomes B. chloroplas

dsp73

Answer:

E. Nucleus

Explanation:

All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.

The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:

EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.

Your home is located in a deep river valley less than a mile from where the river flows into the Gulf of Mexico. A hurricane is

Black_prince [1.1K]

Answer: Go to a shelter farther inland on higher ground.

Explanation:

A hurricane is a tropical cyclone in which the air rotates in low pressure. It is an organized thunderstorm which has no fronts (a boundary that separates the two air masses which are of typically of different densities). The speed of the wind in this cyclone is 74 mph.

Go to a shelter farther inland on higher ground. is the correct approach. This is because of the fact that hurricane can cause the flow of water from the river at high tide. Thus it will be suitable that a person attains a shelter to higher grounds to keep itself save.

First identify the gametes. use pink labels to identify the male and female gamete types and white labels to identify the gamete

Lady bird [3.3K]

I found the whole exercise on the internet. Attached is the scheme with labels for the gametes, f2 generation, and respective frequencies.

For the gametes position, on the left pink square on the male gametes side you should put a capital G, <span>and on the right pink square on the male gametes side you should put a small g, as</span> the only two possible offsprings that are showing is "GG" under the left male gamete and "gg" under the right male gamete. On the top pink square on the female gametes side you should put a capital G, and on the bottom pink square on the female gametes side you should put a small g, as the only two possible offsprings that are showing is "GG" on the same line as the top female gamete and "gg" on the same line as the bottom female gamete.
As for the frequencies of the gametes, you should put the white label that marks 1/2 by the side of each gamete.
Related to the F2 generation, the top right and bottom left pink squares should have the label with a capital G and small g - "Gg" which reflects the combination of the male gamete on its line with the female gamete also on its line.
As for the frequencies of the progeny, each of the genotypes formed from the union of the gametes should have by the side the white label that marks 1/4.
The totals would be that GG is 1/4, Gg is 1/2 (1/4+1/4), and gg is also 1/4.
