Explanation:
This is due to the tilted earth's axis. During the summer, the sun's beams hit the Earth at a steep angle. The light does not spread out so a lot, subsequently expanding the measure of energy hitting any given spot. Likewise, the long daylight hours permit the Earth plenty of time to reach warm temperatures.
1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
Answer:
The phospholipid will form a sphere with the heads inside
Explanation:
Phospholipids are glycerol molecules containing two Fatty acids that is hydrophobia and a hydrophillic negatively charged phosphate.
The phosphate forms the head and the two fatty acids will form the tail
When phospholipid is dropped into a cup of vegetable oil (a lipid). The phospholipid will form a sphere with the heads inside. This is because the heads are hydrophillic and cannot dissolve in the fat hence they will cluster together.

Answer:
The options
A) "Medications are needed to prevent heart failure."
B) "I will take aspirin, atenolol, and captopril indefinitely."
C) "My blood pressure should be less than 130/80 mm Hg."
D) "Daily estrogen will prevent another heart attack."
The CORRECT ANSWER IS D)
D) "Daily estrogen will prevent another heart attack."
Explanation:
A reduction in the natural hormone estrogen levels could be a causative factor in heart disease increase within post-menopausal women. Estrogen is thought to show a positive impact on the inner layer of artery wall, functioning in such a way to keep blood vessels elastic.
In spite of the advantages of estrogen, the American Heart Association speaks against employing postmenopausal hormone therapy to decrease the likelihood of coronary heart disease or stroke as some research works have revealed that it vividly do not decrase the risk of heart attack but increases the likelihood of blood clots and stroke.
