Answer:

b. earth’s strong gravity

Explanation:

On our planet, during the degassing process, the Earth's core was still hot, and a large amount of water in the form of vapor was expelled into the crust. The volcanoes expelled hydrogen gas and water vapor. This process has created our atmosphere. As the temperature went down, there was condensation of the gas, which gave rise to clouds and the consequent occurrence of precipitation, which returned to Earth due to the force of gravity. The water in liquid state was suspended on the surface of the atmosphere, giving origin to the primitive oceans.

With this we can conclude that what made it possible for the planet earth to have liquid water was the presence of a strong gravitational force.

Mkey [24]

Answer:

greater trochanter of the femur

Explanation:

Analogous structures refer to those that are similar morphologically and even have a similar function in the organism, but their genetic origin differs.

The origin and embryological development of these organs are not the same.

Both structures are muscles insertion points or surfaces. These muscles are related to the extremity movement.

Drag each tile to the correct box. Explain the process in which hormones secreted by the pancreas function with respect to incre

olga55 [171]

Answer:

The correct order is:

High amount of glucose in the blood, sending signals toward the pancreas.
Synthesis of hormones by beta cells.
Binding of hormones with receptors on the liver.
Intake of glucose molecules from the blood by specific transporters.
Release of hormones from the receptors

Explanation:

The pancreas produces two hormones important for the regulation of blood glucose levels.
The two hormones, glucagon and insulin, increase and decrease the blood sugar respectively.
Insulin lowers the blood glucose by stimulating the body cells to increase the intake of glucose.
The brain senses high/low blood glucose, then, sends signals to the pancreas to initiate the synthesis of insulin or glucagon by the beta cells.
These hormones bind to receptors on body cells; on hepatic cells, in case of insulin.
The receptors initiate cellular signaling that facilitates intake or exit of glucose in or out of body cells.

Klio2033 [76]

Answer:

Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.

Explanation:

The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
