How does water enter the atmosphere

Answers

the sun evaporates the water from ponds, oceans...etc. There the water turns into water vapor, a gas. Then it participates from the cloud and restarts all over again.

Water enters the atmosphere through a process called evaporation. Evaporation occurs when liquid water, such as that in oceans, lakes, rivers, or even moist soil, absorbs energy from the sun and transforms into water vapor, which is a gaseous state.

The energy from the sun breaks the bonds between water molecules, allowing them to escape into the air as vapor. Once in the atmosphere, water vapor can rise and form clouds through a process called condensation, where water vapor cools and condenses back into tiny water droplets or ice crystals.

Eventually, these water droplets may coalesce and fall back to the Earth's surface as precipitation, such as rain or snow. This continuous cycle of evaporation, condensation, and precipitation is known as the water cycle, and it plays a crucial role in redistributing water across the planet.

How could stem cells prove helpful in the treatment of cardiovascular diseases

Answers

Answer:

Stem cells are self-renewal undifferentiated cells present in the human body. Undifferentiated means that they can divide and differentiate into many cell types of the body depending upon the differentiating potency of the stem cell.

If scientists could regulate the process of differentiation, they can able to differentiate a stem cell into a cell type of interest such as cardiac cell.

These cells are then can be used to replace the damaged or dead cells present in the body.

Thus, it can help in the treatment of diseases such as cardiovascular disease.

stem cell can differentiate to form heart muscle cells.

What component of muscle is described as a bundle of actin, mysoin, and other protien filaments

Answers

The component of muscle which is described as a bundle of actin, myosin, and other protein filaments is referred to as a tendon.

What is a Tendon?

This structure falls under the category of connective tissues and is involved in the attachment of the muscles to the bones as they work together in ensuring adequate movement of body part is achieved.

They made up of different types of proteins such as actin, myosin, and other types of protein filaments and are very flexible which helps them absorb pressure.

This is therefore the reason why tendon was chosen as the most appropriate choice.
