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

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

Answers

The answer is B. Excretory

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.

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.

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.

Answers

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.

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.

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?

Answers

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.
