Answer:
16.3 N
Explanation:
The net force acting on an object is essentially the sum of all its vector forces.
Here, one force is of the ball rolling. Because the force is in the same direction as where the ball is rolling, we will denote it as positive 20 N.
The second force is the force of friction. Friction is the force pushing against an object, so it's moving in the opposite direction as the ball. Hence, we denote that as negative 3.7 N.
Adding these, we get:
20 + (-3.7) = 16.3 N
Scientists have discovered a new molecule found in the blood of wallabies. The molecule contains only carbon, hydrogen, and oxygen. After further examination, scientists discovered that the C, H, and O are in a 1:2:1 ratio. This molecule is most likely a ________.?
Answer:
carbohydrate
Explanation:
The molecule discovered by scientists in the illustration is most likely to be a carbohydrate.
Among all the biomolecules, only carbohydrates have the molecular formula of ([tex]CH_2O[/tex])[tex]_n[/tex]. On the other hand, carbohydrates generally contain carbon (C), hydrogen (H), and oxygen (O) in the ratio 1:2:1.
Since the molecule discovered by the scientists has C, H, and O in the ratio 1:2:1, then, it is, therefore, best thought of as a carbohydrate.

Answer:
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. ... The charge on a single electron is considered as the unit electrical charge

Which of The following are challenges to implementing sustainable farming practices? Select two correct answers.
a. increased need for fertilizer
b. lack of pollinating insects
c. higher initial costs
d. increased erosion
e. increase labor costs
Answer:
I think its A and E
Explanation:
^^^^^^
The challenges to implementing sustainable farming practices: higher initial costs; increase labor costs.
What is sustainable agriculture?It is an integrated system which includes both plant and animal farming practices, which hence has a minimum effect on the environment. It involves using substances of natural origin and hence meets the needs without causing an adverse impact on the environment.
What are its advantages?It prevents pollution since the waste remains in the farm's ecosystem.There is a reduction in the production of waste, and the waste of one is used in the other.It saves energy as there is a lower requirement for non-renewable resources.It doesn't use agrochemicals.It involves methods that reduce soil erosion, like managing irrigation, covering the soil with tillage.What are its disadvantages?It takes more effort since the use of machines is minimal.Limited use of land and hence, mass production is not possible.What are the challenges?New farmers have to struggle with high labor demand since it involves less use of machines and hence more workers are required.Before harvesting their first crop, young farmers require a huge sum of up-front capital, which is even more for biologically diverse farms.Hence the correct options are (c) and (e) higher initial costs; increase labor costs.

What organisms in the ocean absorb the most carbon dioxide?
A. fish
B. ocean mammals, like whales and dolphins
C. algae and marine plants
D. coral
Answer:
im pretty sure its C
Explanation:
Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique functions do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Answer:
Microvilli is very common in these cells. They increase the absorption area.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.
