1. What interactions affect protons in an atomic nucleus? More than one answer may be correct.
(a) the nuclear interaction (b) the weak interaction (c) the electromagnetic interaction (d) the gravitatioNl interaction
Answers
In the nature there are four fundamental forces, namely nuclear force, electromagnetic force, weak force, and gravitational force. These forces are arranged with respect to their strengths in descending order.
The nuclear forces are of greater strengths.
These bind up the protons and the neutrons in an atom together. The nuclear forces are strong enough to combine the quarks that form the nucleons.
B= The weak forces of the interaction are the forces that are short ranged and cause the instability of the nucleus. These are 1/10^5 times of the nuclear forces.
C= The electromagnetic forces are the forces that which combine the atoms and the molecules that intend form the ordinary matter. The electromagnetic forces are 1/10^5times of the nuclear forces.
D= The gravitational forces are 1/10^5 times of the nuclear force.

Which individual is a producer?
a host who seats customers in a busy restaurant
O a mother who demands quality produce for her family
O a farmer who grows only what his family needs to survive
© a student who builds a bookcase from bricks and boards
A
Answers
The individual who can be referred to as a producer is a farmer who grows only what his family needs to survive. Thus, the correct option is C.
Who is a producer?In a food chain, the producers are the organisms which can produce their own food without the help of other organisms. Generally, plants are called the producers of an ecosystem because they produce their own food and gain sustenance from the process of photosynthesis. The process of photosynthesis allows plants to produce food such as glucose (carbohydrate) which is a sugar energy. The breakdown of glucose results into formation of energy in the form of ATP (Adenosine Triphosphate).
The farmers can be referred to as producers as they are growing their own food.
Therefore, the correct option is C.

Answers
Answer:
alright bet I got this
Explanation:
Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.
Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.
After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.
Which of the following statements correctly describes the relationship between biodiversity and sustainability? (1 point)

O Biodiversity and sustainability both increase when the number of species in an ecosystem increases.
O Biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
O There is no relationship between biodiversity and sustainability.
Answers
The statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
What do you mean by Biodiversity?Biodiversity may be defined as the sum total of all the living organisms living in a particular ecosystem.
As the number of species increases, biodiversity also increases because both are directly proportional to one another.
While the species enhancement negatively impacts the sustainability of the environment.
Therefore, the statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.
