The students on the right are applying a force of 100 N to
the right. This is shown by the red arrow. The students on
the left are applying a force of 100 N to the left. This is
shown by the blue arrow.
F = 100 N
F = 100 N
X
Blue team
Red team
Which action is most likely to make the team on the left win?
A. Adding one student to the team on the right
B. Instructing both teams to pull a little less so that each side is
applying only 50 N of force
C. Adding one student to the team on the left
D. Instructing both teams to pull harder so that each side is applying
150 N of force
Answer: C) adding a person on the left
This additional person will pull more force to the left side and help that team win the tug-of-war.
Choice A is the complete opposite of what we want, since it helps the red team win. Choices B and D won't change the current state because the same thing is happening to both sides. So we can rule out choices A, B and D.

upper part of their body and lighter
underneath. This type of
camouflage is called...
a) warning coloration
b) countershading
c) mimicry
d) none of the above
Type the letter,
Answer:
B
Explanation:
Countershading is a form of concealing coloration in which the upper surfaces of the body are more darkly pigmented than the unilluminated lower areas, giving the body a more uniform darkness and a lack of depth relief.

A major difference between eukaryotes and prokaryotes is that __________. A major difference between eukaryotes and prokaryotes is that __________. some eukaryotic cells live in areas of temperature extremes whereas prokaryotic cells cannot prokaryotic cell structure is much more complex than eukaryotic cell structure eukaryotes were the first cell type on Earth eukaryotic cells contain the genetic material DNA whereas prokaryotic cells contain RNA eukaryotes' survival is limited to a few environments whereas prokaryotes have adapted to a variety of environments
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.

What is the main function of the endocrine system?
A. secrete hormones
B. send nerve impulses
C. produce blood cells
D. produce DNA
Answer:
A. secrete hormones
Explanation:
Endocrine glands release hormones into the flowing bloodstream, which lets them travel to cells in other body parts. These endocrine hormones help control mood, growth & development, the way our organs work, metabolism, and reproduction.
Answer:
A secrete hormones
Explanation:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.

What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
D. 18
Explanation:
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.

How is the atmosphere a system, include components, inputs, outputs & flow.
Answer:
the flow in systems besides the flow.
Explanation:
Answer:
When studying Earth as a whole, our primary input is energy from the sun and from space. Earth outputs heat and light to space, maintaining an approximate overall steady-state with respect to energy.
Explanation:
Molecular chaperones can work by creating an "isolation chamber." What is the purpose of this chamber? Question 6 options: The chamber acts as a garbage disposal, degrading improperly folded proteins so that they do not interact with properly folded proteins. This chamber is used to increase the local protein concentration, which will help speed up the folding process. This chamber serves to transport unfolded proteins out of the cell. This chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol, until protein folding is completed.
Answer:
Providing them with a suitable hydrophobic environment for correct folding
and return to its native form
Explanation:
The chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol until protein folding is completed.
Chaperones, also known as heat shock proteins, act to correctly fold proteins after their synthesis.Some of the most important chaperones include Hsp60, Hsp70 and Hsp90.Thus, chaperones prevent proteins from aggregating into nonfunctional structures.In conclusion, the chamber serves to protect unfolded proteins from interacting with other proteins in the cytosol until protein folding is completed.

how can you separate iron filings from sand through which process
Answer:
Process called magnetic separation
Explanation:
The magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using magnetic force.
This method is also used to separate the mixture of sand and iron fillings as iron is attracted by magnet.
Answer:
Use a magnet to separate the iron filings from sand since iron is magnetic

can anyone help with one or two of these questions? ill give brainliest
Answer:
1. 1.00(1/2)^151/30.2= 31.3 g
2. 24g-->1.4 g = 4 half-lives, so 4*5730= 22920 years
3. 64g-->2.0g = 5 half-lives, so 12.5/5= 2.5 hours
