4 0

Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.

Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY).

juin [17]

Answer:

The correct option is a. lacks organelles beyond ribosomes.

Explanation:

All cells of higher organisms are bounded by a cell membrane (also called plasma membrane or plasmalema) and contain cytoplasm that surrounds one or more nuclei. Within the cytoplasm there are structures known as organelles, which are specialized in carrying out the metabolic processes of the cell, these cells are called eukaryotes. The prokaryotes are smaller, lack a differentiated nucleus and organelles. The prokaryotic cells are not internally divided by membranous walls, but consist of a single space.

Both prokaryotic and eukaryotic cells contain ribosomes. Ribosomes are organelles not delimited by membranes, these organelles are important since a cell makes all its proteins in its ribosomes.

Which is easier to identify: prophase, metaphase, anaphase, or telophase?
Romashka [77]

Answer:

metaphase

Explanation:

The easiest stage of mitosis to identify under the microscope is the metaphase stage.

<em>The stage is characterized by the alignment of chromosomes at the center (the equator) of the cell forming what is known as the 'metaphase plate'. The metaphase plate can easily be seen at a glance under a focused microscope. Other stages of mitosis are continuous and will take a bit of effort to pinpoint a particular stage from the transition stage. </em>
