A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The stude

nt keeps a cricket in an enclosed box that is heated to different temperatures each day for twelve days. The student records the cricket’s chirps by using a sound-activated microphone so the timing of the chirps can be measured. Which is the dependent variable in this experiment?

Inessa05 [86]

Answer:

They concluded that the cell is eukaryotic cell.

Explanation:

Prokaryotic and eukaryotic cells are the two types of organisms. Prokaryotic organisms are the organisms made up of prokaryotic cells and eukaryotic organisms are made up of eukaryotic cells.  

Prokaryotic cells do not have a nucleus and other membrane-bound organelle and eukaryotic cells have a nucleus and other membrane-bound organelles like mitochondria.  

Therefore if the cell has mitochondria they must conclude that the cell is eukaryotic because the prokaryotic cell does not have mitochondria as it is a membrane-bound organelle.

A student compares the four distinct cells that could form from the stem cell after differentiation. Which statement accurately
e-lub [12.9K]

Answer:

The statement that accurately compares and contrasts the red blood cell and the white blood cell is that both have the same copy of DNA, but different genes are expressed in the two cell types.

Explanation:

Red blood cells (RBC) and white blood cells (WBC) are two highly differentiated types of cells that come from the hematopoietic system and have different functions in the blood.

Compared to WBC , RBC cells lack a nucleus and have fewer organelles, and their function is to transport gases in the blood, unlike the former which are involved in the body's defence.

<em>Cell differentiation is based on gene expression of the genome, resulting in different types of proteins synthesized in each cell, which give them a different structure and function. </em>

Both <u>WBC and RBC have the same genome</u>, but different genes are expressed in each, giving them different morphological and functional characteristics.

arsen [322]

Answer:

E. 1/600

Explanation:

Hint:

The probability of fixation of a new neutral mutation is 1/(2N)

Given N as 300

= 1/(2×300)

=1/600

Therefore,

1/600 gives a sure fixation of one allele from the large population
