What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet

Answers

Answer:

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells?

Explanation:

1.The cell membrane holds the cell's internal contents from its environment

2.the nucleus, the cell's "brain", holds the cell's DNA in the form of chromosomes, and makes protein codes that tell the other organelles to function in a certain way once the codes are made into literal proteins and passed around the cell

3.The cytoplasm is the gelly fluid inside the cell. It is the place for chemical reaction, and provides a place where other organelles can operate within the cell properly, and the cytoplasm keeps the cells from moving around.

4. The main job of the mitochondria is to convert nutrients into energy through cellular respiration, making ATP. the mitochondria are known as the powerhouse of the cell.  In addition to supplying energy, the mitochondria is involved in a range of other processes,like signalling, cellular differentiation, cell death, as well as control of the cell division cycle and cell growth.

How to use bacteria as a treatment for sewage waste

Answers

Answer: hope this helps

Explanation:

Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.

Explanation:

Biological wastewater treatment is the most common method of sanitation in the world. This technology uses different types of bacteria and other micro-organisms for the treatment and cleaning of polluted water.

Wastewater treatment is as essential to human health as it is to environmental protection. Indeed, the use of these bacteria accelerates the treatment of pollution on a small surface: the purification plant. It’s better than letting the river handle it, because even though it’s the same purification process that occurs in nature, the quantities of pollution discharged today are too high to keep the natural cycle intact.

Thus, sewage treatment plants can prevent eutrophication of rivers, for example, but also prevent the diffusion of diseases.

Municipal and industrial effluent is the main source of wastewater. And thanks to the use of micro-organisms, we are able to degrade the content of these organic wastes as they are used as a source of food and energy to grow and multiply.

is a grasshopper a herbivore carnivore or omnivore

Answers

Grasshoppers are well-known plant-eating insects that are herbivores.

Their typical diet consists of a variety of plant material such as grasses, leaves and plant stems. They chew and eat plant matter using their powerful jaws. Grasshoppers' digestive tracts contain symbiotic microbes that help them digest cellulose, a complex carbohydrate found in plants.

Although the primary trait of grasshoppers is herbivory, it is important to note that under certain circumstances, particularly when resources are limited, some species may engage in cannibalism. However, they are clearly classified as herbivores because of their overall diet and ecological function in the ecosystem.

suppose you and a friend are making iced tea using identical glasses. You both use the same amount of water, and the water temperature is the same in both glasses. Explain how you can tell who added more ice tea mix to the glass.

Answers

Answer:

Iced-Tea Problem

220 g of 35˚C tea (water) is poured over 250 g of -10˚C ice.

What happens...

The warm water (tea) will cool down to 0˚C. As it cools the ice will heat up to 0˚C and then start to melt.

There is plenty of ice however and only a portion of it will melt. Find the amount of ice that melts into water

and you’ll know the final composition and even the dilution factor on the tea.

Cool tea water down to 0˚C

4.184 J/g˚C · 220 g · 35˚C = 32216.8 J removed to cool tea to 0˚C

Warm ice up to 0˚C

2.09 J/g˚C · 250 g · 10˚C = 5225 J to heat ice up to 0˚C

This heat comes from the cooling water, so substract this amount off the total above

32216.8 - 5225 = 26991.8 J of heat that will MELT the ice

mass of ice melted = 26991.8 / 334 = 80.8 g of ice melted

220 g + 80.8 = 300.8 g of water

250 g - 80.8 = 169.2 g of ice

final mixture for

my glass of iced

tea all at 0˚C

220.0 g original tea

300.8 g final tea

The dilution factor is simply the original volume

over the final volume (or masses here ). = .731 or 73.1%

of the original

concentration

If I’m going to get a dilution of 73.1%, I should

compensate by mixing my tea in 26.9% LESS

volume than the directions state. So I will not dilute

the tea to 2 quarts (64 oz), but rather to 1.462

quarts (46.8 oz).

It’s hot and I want a glass of iced tea as soon as possible. The directions for my tea say to boil some water,

add 2 tea bags (these are the big bags), steep for 4-5 minutes, then add enough water to make 2 quarts which

turns out to be a pitcher of tea. However, if I make this tea the exact concentration I want now, when I pour

it over ice the ice will melt (because the tea will still be quite warm) and my tea will be too dilute. So I

calculate how much stronger I should make the tea KNOWING I will pour the warm tea over ice to make

my glass of iced tea.

(a). What is the final temperature and composition of the glass of iced-tea?

(b). What will be the concentration of the tea relative to the original concentration?

(c). How concentrated should I mix the tea knowing that it will be diluted when

poured over the ice?

(a)

(c)

(b)

only 73.1% of the full

amount to compensate

Why did Ibrahim conclude that the dorsal spines were not used to support a hump or to regulate body
temperature?

Answers

Chemical composition of dorsal spines provides information about its function as regulation of body temperature.

The dorsal spines were not used to support a hump or to regulate body  temperature because of the chemical composition of the spines. Ibrahim found that the spines were made up of bones having few blood vessels and were likely wrapped tightly in skin which can't perform the function of thermoregulation in the body.

In order to regulate temperature of the body, more blood vessels are needed and we know that in dorsal spines the structure is bony and less number of blood vessels so we can conclude that chemical composition of dorsal spines provides information about its function as regulation of body temperature.
