Pill bugs are placed in a container where they have a choice of a wet or dry environment. researchers record how much time was spent on each side.

Answers

Answer:

This question is incomplete; the complete question is as follows:

Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side. What is the INDEPENDENT and DEPENDENT variables?

The independent variable is WET OR DRY ENVIRONMENT

The dependent variable is TIME SPENT

Explanation:

The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to bring about an effect on the dependent variable.

Conversely, the dependent variable is the variable that the experimenter measures in an experiment. It is dependent on the independent variable.

In this question, the researchers placed pillbugs in containers that are either WET or DRY in order to measure how much time they spent in each side. Hence, the independent variable is the WET or DRY environment the pillbugs were placed because it is what the researcher changes while the dependent variable is the TIME SPENT because it is what the researchers measure.

How MDMA affects the synapses in the brain

Answers

Answer:

MDMA affects the brain by increasing the activity of at least three neurotransmitters (the chemical messengers of brain cells): serotonin,89,90 dopamine, and norepinephrine.91 Like other amphetamines, MDMA enhances release of these neurotransmitters89–92 and/or blocks their reuptake,93,94 resulting in increased neurotransmitter levels within the synaptic cleft (the space between the neurons at a synapse).

Which of the following are final destinations of proteins directed to the secretory pathway? ▼endoplasmic reticulum ▼mitochondria ▼the plasma membrane ▼the outside of the cell▼ the nucleus ▼the golgi apparatus ▼lysosomes A. TRUE B. FALSE

Answers

Answer:

False, the final destination is the outside of the cell

Explanation:

The secretory pathway moves proteins to the cell membrane, where they are released to the extracellular medium. In this pathway, the proteins enter into the membrane of the rough Endoplasmic Reticulum (ER) in a cotranslationally way (i.e., during their synthesis in ribosomes). This pathway can be summarized by the following transporter activities: Endoplasmic Reticulum >> Golgi apparatus >> secretory vesicles (such as lysosomes) >> cell membrane, where proteins are finally released by exocytosis.

Sirius A is 8.6 light-years from Earth. What is this distance in Kilometers?

Answers

Answer: 81,362,880,000,000‬ kilometres

Explanation:

A Light year refers to the distance that light travels in a year.

Light travels at a rate of 300,000 km/s.

This means that in a year it travels;

= 300,000 * 60 seconds * 60 minutes * 24 hours * 365 days

= 9,460,800,000,000‬ km in a year

Sirius A is therefore;

= 9,460,800,000,000‬ * 8.6

= 81,362,880,000,000‬ kilometres from Earth.
