1. Melissa raises crickets at her pet store that she
harkovskaia [24]

Answer:

a. Manipulated variable: TEMPERATURE

b. Responding variable: CRICKET CHIRP

c. Controlled variable: Same species of cricket

d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more

Explanation:

Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.

Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.

Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.

Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.

What is the function of the following organelles?
MrRa [10]

Answer:

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.

The plasma membrane is the same as a cell membrane

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
