Question 1: Some cells produce and secrete high levels of digestive proteins. Which organelles would you expect to be abundant i

n those cells, and why? Question 2: Explain how active transport helps a nerve cell maintain its resting potential. Question 3: The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater. ( Will Mark Brainliest).

Answer:

q1 : ribosomes because they are responsible for protein synthesis

q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient

q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body

Brainliest:Both the euglena and paramecium seen here have___?
forsale [732]

Answer:

projections that help them move

Explanation:

Euglena and paramecium both belong to the Kingdom Protista. They are very minute single cellular organisms but have many differences among them. Paramecium is more similar to animals in many of its characteristics while Euglena is more similar to plants in its characteristics. This is because Euglena just like plants can make their own foods through chloroplast while paramecium just like animals cannot make own food.

However what is common in both of these are projections that help them move . Paramecium have projections called cilia around the whole body while Euglena has a whip like flagella which helps it to move.

Hope it help!

John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece
Zinaida [17]

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100
