Explain the difference between the effects of balanced and unbalanced forces on an object. To receive full credit you must mention net force and whether the motion will change or not.
Answer:
Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the change the object's motion.The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force

Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity?
Answer:
The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Explanation:
As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.
Please help me I really need help I am having a hard time with this question.
Answer:
I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.
Amagnetwith alength of 10cmwasgiven to Meera and shewas told to break themagnetinto3 pieces.Before breaking the magnet had 1 north and 1 south pole. How many north and south poles will the magnets now havetotally in all the 3 broken pieces?
Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.

Na3C6H507
Answer:
Explanation:
Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.

A) they are creating super bugs
B) they are producing more crops
C) there is not enough research
D) there are changing natural ecology
Answer:
B) They are producing more crops

Diversity among members of a species is important because diversity
a
increases the chances of survival under changing conditions.
b
ensures high levels of competition.
c
increases the available ecosystem resources.
d
ensures the variety of reproductive methods for a species.
Diversity among members of a species is important because diversity increases the chances of survival under changing conditions.
If a disease spreads throughout a species, the species with genetic diversity will survive. If the species does not have genetic diversity, they will be wiped out by the disease.

A patient has swollen feet, ankles, and legs, and has pain in his lower back. Tests show the level of urea, a waste product, in the patient's blood has suddenly risen. Which body system is most likely not functioning properly?
A.
Nervous
B.
Excretory
C.
Digestive
D.
Reproductive
The body system that is most likely not functioning properly is excretory system. The correct option is B.
What is excretory system?The excretory system is a detached biological mechanism that removes excess, unneeded materials from an organism's body fluids to help maintain internal chemical homeostasis as well as prevent body damage.
The excretory system's function is to remove waste from the body. Water, CO2, nitrogen, salts, and heat are among the wastes. Metabolism refers to the process by which the body converts food into energy.
The primary function of the kidneys is to eliminate excess water and wastes from the bloodstream through the production of urine, a liquid waste.
As the patient has swollen feet, ankles and legs and having urea level boosted in blood, it means his excretory system has some problems.
Thus, the correct option is B.

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph
Answer: definitely C will help you
Explanation:
Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
What is the main reason of emission of carbon?According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.
This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.
These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.
Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.
