which body system is made up of the heart, veins, and arteries?

Answers

Answer:

The circulatory system

Explanation:

The heart, veins and arteries works together to service the cells of the body

That would be the circulatory system. The heart pumps nutrients and fresh oxygen through the arteries, and the veins take blood with less oxygen back to the heart. The arteries carries nutrients and oxygen to body tissues.



Why does water have a strong surface tension and why is this important?

Answers

Why does water have strong surface tension?

The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding. ... Formed bonds are called hydrogen bonds which lead to strong cohesive forces between the water molecules and high surface tension of water.

Why is it important?

The surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into spherical shapes. Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets.

Explanation:

The only way to tell if the red blood cells are crenated is to observe them under a microscope

What is crenation?

Crenation is the process of red blood cells becoming misshapen and breaking apart, and this can be seen through the examination of red blood cells under a microscope.

By observing the shape of the red blood cells, it can be determined if they are crenated or not. Additionally, other methods such as hemoglobin analysis or measuring the osmotic fragility of the red blood cells can also be used to determine if crenation has occurred.

Moving to the next question prevents changes to this answer.

Answers

Newly synthesized proteins destined to be secreted from the cell are likely to be found in all the options except the lysosome.

Both the endoplasmic reticulum and Golgi apparatus are involved in protein processing and transport.

However, the lysosome is an organelle responsible for digesting or degrading excreted biomolecules as well as dead organelles. The lysosome is spherical and most contain digestive enzymes capable of degrading biomolecules in its lumen. Thus, a protein destined to be secreted from the cell will most likely not be found in the lysosome, otherwise, the protease enzyme present in its lumen would degrade them.

What is Hemoglobin?

Hemoglobin is defined as an iron-containing oxygen-transporting metalloprotein present in the red blood cells of nearly all vertebrates as well as the tissues of some invertebrates that carries oxygen from the respiratory organs in the blood to the rest of the body.

The blood protein hemoglobin that helps carry oxygen throughout the body and carbon dioxide to your lungs. High hemoglobin levels can cause dizziness, fatigue, easy bruising, and other symptoms.

The iron which is present in hemoglobin which is removed is recycled from the red bone marrow.

PLEASE HELP DUE SOON 40 POINTS!

Answers

Answer:

earth's atmosphere

Explanation:

The descriptions below explain two ways that water is used by plants on a sunny day.

I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.

Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?


A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.

B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.

C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.

D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

Answers

The answer is A.
During the process of transpiration the plant sucks the water up through its roots this is a physical change. But, it only goes through a chemical change after the process of photosynthesis because the plant will use sunlight, carbon dioxide, and water and convert it into glucose and oxygen.
