Answer:

To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.

In which areas of the brain would a stroke mimic damage to cranial nerve 2
Dmitry_Shevchenko [17]

The occipital lobe is the area of the brain that a stroke would affect to mimic damage to cranial nerve 2.

We can arrive at this answer because:

  • Cranial nerve 2 is the optic nerve, responsible for visual information.
  • This nerve is directly connected to the occipital lobe.
  • In this case, when a stroke affects the occipital lobe, cranial nerve 2 can be affected and if this happens the optic nerve will have problems.

Optic nerve problems can cause defects in the field of vision, impede central vision, not allow the eyes to focus on a particular element, and have centrocecal or altitudinal problems.

Distinguish between first-generation pesticides and second-generation pesticides used by people to combat pests, and give an exa
Lady bird [3.3K]

Answer:

No short answer.

Explanation:

First and second generation pesticides differ vastly in terms of their contents and effects.

First generation pesticides were used in early 20th century up until the 1940's and they consisted chemicals such as mercury and lead which were not biodegradable and they started adding up in the soil until it was not fertile anymore. Second generation pesticides were divided into three groups as chlorinated hydrocarbon, organophosphates or carbamates and consisted of chemicals that were less harmful for the soil and did not accumulate over time. Some examples to second generation pesticides can be DDT or dimethoate.

Broad spectrum and narrow spectrum pesticides have the difference of effective range between them. Narrow spectrum pesticides are designed to target a specific organism such as a specific plant or an insect whereas broad spectrum pesticides are applicable to a wider range of organisms and still have the same effect for each.

Chitin Inhibitors can be given as an example of narrow-spectrum pesticides and the second generation pesticides in the answer can be given as an example of broad-spectrum pesticides.

I hope this answer helps.

Why was it important to allow all the investigation materials to assume room temperature before beginning the experiment?
hram777 [196]

Answer:

The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.

Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.

Which experiment is more likely to be reliable, and why ?
tigry1 [53]
Since there’s nothing here other than what you’ve asked i’ll guess, an experiment that is more likely to be reliable will not use the first values it gets, will be done multiple times and the values will be close in number
