What are cell organelles ?

 

Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.

Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.

Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria  generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

What drives surface currents?

differences in air temperature

differences in climate

differences in water density

differences in water salinity

Answers

Answer:

WHAT DRIVES SURFACE CURRENTS?

Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.

DIFFERENCES IN AIR TEMPERATURE.

Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.

DIFFERENCES IN CLIMATE.

Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.

DIFFERENCES IN WATER DENSITY.

High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.

DIFFERENCES IN WATER SALINITY.

As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

ILL GIVE BRAINLIEST, 6 - 10 sentence paragraph telling me the difference between Weather and Climate.

Answers

Weather refers to short term atmospheric conditions, while climate change refers to long term changes. Weather is the day-to-day state of the atmosphere, and its short term variation in minutes to weeks. People usually think of weather as the combination of temperature, humidity, cloudiness, it’s visibility by look , and wind. As an example you wake up in the morning and you are to take a step outside. You look at the sky,it is foggy, that is a representation of the weather for that day. That same weather that you saw might change over the course of the next morning and rain, or you may see a perfect sun, these are all representations of weather and how it is a short term outlook. Climate change is how the characteristics of the weather we experience in a certain place change. 'It can get hotter or wetter on average or have more concentrated rain in a short period, but then get longer dry periods. Although weather does effect our climate it is the weather patterns that cause a long term effect on our daily world.

What is cellular membrane?

The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.

The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

Lipids (phospholipids and cholesterol), proteins, and carbohydrate groups attached to some of the lipids and proteins are the primary components of the plasma membrane.

Membrane lipid molecules are classified into three types: phospholipids, cholesterol, and glycolipids.

Glycerol is a three-carbon molecule that serves as the membrane lipids' backbone.

Thus, these are the three molecular components of cell membranes.

American apple cells contain an enzyme that turns the tissues brown when an apple is peeled and left for a time. Boiled apple does not go brown. Explain why the boiled apple behaves differently.

Answers

Answer:

I think I got it from recipetips.com

When cooking apples it is not as much of a concern because once they are cooked, the browning will stop. When fresh apples are peeled or cut open, the apple's cells are exposed and react with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the apple brown.

Explanation:

Enzymes are proteins. As such they are very specific. When the apple is boiled, the enzyme becomes denatured and as such doesn't turn the apple brown.
