Hello.
They are different because ionic and covalent bonds are closer then hydrogen bonds. And ionic and covalent bonds have a i<span>ntramolecular </span>bond becasue that is were the force excist.
Ionic bond<span> strengths range from 600 kJ/mol to 6000 kJ/mol.
</span>Covalent bonds<span> form when two atoms share electrons.
Have a nice day</span>
The <u>brachial artery</u> is located in each upper limb, therefore it supplies the upper limb and the lower limb's main arterial vessel is called the <u>femoral artery</u>.
<h3>What is brachial artery?</h3>
It is the main blood vessel that is responsible for transporting oxygenated blood to supplies the upper limb from where the arm begins until it divides into two branches (radial and ulnar), and culminates in the hand and fingers.
<h3>What is femoral artery?</h3>
The femoral artery is located in each lower limb, specifically in the anterior and internal part of the thigh, to later become the popliteal and tibial arteries, it transports the blood with oxygen that comes from the left ventricle.
Therefore, we can conclude that the femoral artery is a pathway that belongs to the vascular system, which supplies the lower limb's, and the brachial artery is a prominent blood vessel that is responsible for irrigating the tissues located in the upper limb.

Answer:
Explanation:
1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.
2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
the first answer as blood needs to be oxygenated to be passes round the body then when its deoxgenated it will return to the heart to be pumped around the body again
Agriculture negatively affects reef ecosystems because the soil and the sea have a direct interaction of substances and minerals that can be altered with the intensification of agriculture.
<h3>What is agriculture?</h3>
Agriculture is a human activity that is based on planting seeds in the ground so that they develop and form plants that have uses such as food or others.
This is one of the oldest activities of humanity and has allowed communities to develop and create trading systems, wooden constructions, navigation, among others.
<h3>What impact does agriculture have on the reefs?</h3>
Agriculture generally takes place in coastal areas or near rivers because the composition of the soil must have certain minerals necessary for plants to grow.
Additionally, the components of the soil go underground to the sea and provide the water with different substances that contribute to marine life. However, the use of pesticides and other agricultural chemicals could reach the sea through runoff and affect the reefs.
