When the sun impacts weather, an interaction with the __________ takes place.
Nadya [2.5K]

Answer:

Hydrosphere

Explanation:

When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.

Weather is the atmospheric condition of a place over a short period of time.

The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.

This water in the atmosphere is forms rainfall, one of the elements of weather.

The sun causes an impact on weather by causing evaporation of water into the atmosphere.

This interaction takes place in the hydrosphere.

a cell is placed in a solution of 3% starch and 3% glucose. After several hours, glucose is detected outside of the cell, but st
Alex17521 [72]

Answer and Explanation:

The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.

Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.

The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.

Which of these is not a property of lymphatic capillaries?
Inessa05 [86]

Answer:

They are smaller than blood capillaries.

Explanation:

Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.

Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up  of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.
