Explain why the wound of a diabetic patients fails to heal heal easily?
[tex]\large\huge\green{\sf{Answer:-}}[/tex]
When white blood cells are unable to function correctly, the body is less able to fight bacteria and close wounds. People with uncontrolled diabetes may develop poor circulation. As circulation slows down, blood moves more slowly, which makes it more difficult for the body to deliver nutrients to wounds.
the larynx, trachea, bronchi, and bronchioles all make up the
Answer:
Lower Respiratory Tract
Explanation:
The lower respiratory tract or lower airway is derived from the developing foregut and consists of the trachea, bronchi (primary, secondary and tertiary), bronchioles (including terminal and respiratory), and lungs (including alveoli). It also sometimes includes the larynx, which we have done here. This is where gas exchange actually takes place.
What is one important difference between savannas and temperate grasslands? A. Savannas only rarely experience fires. B. Temperate grasslands are mostly treeless. C. Savannas are inhabited by grazing mammals. D. Temperate grasslands have nutrient-poor soil.
The one important difference between savannas and temperate grasslands
is that Temperate grasslands are mostly treeless.
Temperate grasslands have varying types of plants and animals in the
region. They have very few trees and are mainly dominated by grasses.
The temperate grasslands have lesser amount of rainfall than the
savannas.
The Savannas have different types of plants ranging from shrubs to
woody trees. The temperate grasslands have nutrients due to the
formation of organic matter from dead plants leaves and roots and aren't
generally regarded as having nutrient poor soil.

If two trucks have the same mass, but truck A is traveling 15 km/h, and truck B is traveling 30 km/h, what statement is true? Question 2 options: Truck A has greater kinetic energy. Truck B has less kinetic energy. Truck B will have a greater stopping distance. Truck A will have a greater stopping distance.
Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.
The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.
From the following expression
Speed = Distance/Time
Distance = Speed*Time
More on the kinetic Energy
Following from the given problem truck B will also have more kinetic energy because it velocity is more
Formula
KE= 1/2mv^2
Hence the more the velocity for a constant mass the greater the Kinetic energy

The Smiths went to dinner at Cheesecake Factory and their bill was $123.75 plus 7.5% sales tax. What is the total bill? Round to the nearest cent.
The total bill that was given to the Smiths at the Cheesecake factory was $133.03
An equation is an expression used to show the relationship between two or more numbers and variables.
Given that the Smiths bill was $123.75 plus 7.5% sales tax. Hence:
Total bill = $123.75 + Sales tax
Sales tax = 7.5% of bill = 0.075 * $123.75 = $9.28
Total bill = $123.75 + $9.28 = $133.03
The total bill that was given to the Smiths at the Cheesecake factory was $133.03

Explanation:
Using 3-5 sentences explain how human activties can affect climate change.
Answer:
Human activities can affect climate change because of just how much waste we produce. One huge example is our burning problem, which slowly strips away at the ozone layer that protects animals from heat and melting snow. Because of the ozone layer, the arctic has been protected for many years but now it's slowly disappearing, melting ice and killing animals who have not learned to survive in such hot weather. Another example is when humans cut down too many trees to sustain the environment; it often causes a massive lack in natural oxygen and unroots many homes of small critters and worms. In conclusion, humans can heavily affect climate change because of our ignorance and how we refuse to learn for the future.
