In sonography, high frequency sound waves are being used in order to generate images of organs, tissues or any parts inside the body. This is a common diagnostic tool that is done for medical purposes. How this has helped in advance medical science is that, it helps in detecting and determining any abnormalities inside the body without doing a surgery first.
The process which is directly affected by the cardiovascular system is HEALING OF CUTS.
The human cardiovascular system is made up of the heart and the blood vessels. The heart is the major player in circulation as it is the one responsible for movement of blood round the whole body. Thus, either directly or indirectly, it affects all the processes that goes on in the body. The healing of cuts is directly affected by the cardiovascular system. Healing of cut occur in four stages and all these stages required different specific materials such as platelets, macrophages, etc that are located inside the blood. It is the responsibility of the heart to pump blood to the injured area and to delivered these needed particles to the wound site.
Answer:
The correct answer is hydrogen bonding.
Hydrogen bond is defined as a weak bond that results from electrostatic attraction taken place between hydrogen of one molecule and electro-negative atom of same or different molecule.
In water, partial negative charge is present on oxygen atom which attracts the partial positive charge present on hydrogen atom of other water molecule. This attractive interactions lead to the formation of inter-molecular hydrogen bonding.
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
Hurricanes form when warm, moist air rises over the water. Cooler air replaces the rising air. Mr. Gaines's class identified that the pressure in the center of the hurricane is decreasing which indicates the storm is getting stronger as the wind increases, i.e., option 3.
<h3>What is a Hurricane?</h3>
A hurricane is a powerful cyclone that is tropical and forms in the Atlantic or Northeast Pacific Oceans.
Surface atmospheric pressure is fairly low in the center of a hurricane. An eye forms in the center of the storm system as it rotates faster and faster. With very low air pressure, it is very calm and clear in the eye.
Thus, the correct option is 3.
