I will say the answer is either A or B
Explanation:
A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

How the nervous and endocrine systems maintain homeostasis?
Answer:
Hope this helps :D
Explanation:
Homeostasis is the process of how you have a controlled body temperature.
The nervous system detects that your body temperature is falling (or rising) so the endocrine system send the chemical messengers (hormones) to bring the body temperature back to normal.
If a plant cell needs energy for endocytosis, what does it use and where does the energy come from?
Explanation:
Active transport uses energy stored in ATP to fuel the transport. ... Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules.
Hope this helps!
If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.
Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reproductive cells, which are sperm and egg cells
Chromosomes in "most cells of the organism"(somatic cells) are diploid and the chromosomes are grouped in pairs while the chromosomes in reproductive cells are not paired so there are half the number that would be found in somatic cells so the sex cells are haploid.

Is baking soda organic or inorganic explain why?
Answer:
Inorganic
Explanation:
Baking soda can be found as a naturally occurring compound, but is more frequently manufactured from other naturally derived materials, like trona ore. Baking soda can be produced by the reaction of carbon dioxide and soda ash, a naturally occurring mineral. To my knowledge there is not an “organic” baking soda.

Drag the correct tRNA anticodon into the ribosome. Therefore, A matches U and C matches G.
What is the UAC anticodon?The Ribosome Workbench uses the AUG codon as a universal signal to initiate translation. Because the methionine-bound tRNA has the anticodon sequence UAC, the AUG start codon signals the ribosome to insert into the amino acid methionine.

Studying which of the following would provide the best evidence that two organisms share a common ancestor?
A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions
Answer:
A
Explanation:
Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.
Amino acid sequence is a series of bases with different letters usually four(A T C G or U) this letter contains information of an individual when translated.
The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast
Blast generates alignments or similarities between a amino acid or protein sequence.For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.
Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.
