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.

Answers

Answer 1

The box would stay at rest where it lies since the same amount of force is pulling it in opposite directions :)

Answer 2

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.

Hypertonic

Explanation:

Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

Plants help remove some toxins from the air.

Some plants pollinate with help from the wind.

Identify: What are the reactants of aerobic cellular respiration? What are products?

Answers

Answer:

Aerobic breathing disrupts glucose and combines disintegrated products with oxygen that generates water and carbon dioxide. The carbon dioxide is a waste of aerobic breathing because there is no demand for cells.

Cellular respiration reactants:

Glucose and oxygen.

Cellular Respiratory Products:

CO2 and water (H2O); ATP & Heat

Anaerobic breathing: breathing occurring in the absence of oxygen that makes certain ATP still alive to cells.

Explanation:

Cellular Respiration is the mechanism that releases energy in the presence of oxygen by breaking down food molecules.

Cellular breathing = Aerobic breathing

In mitochondria, aerobic breathing takes place.

Some of the energy generated by food decomposition is stored as ATP and some as heat.

ATP is an energy storage molecule used by every cell as its source of energy.

"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?

Answers

Answer:

by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species

Explanation:

The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

Explain how ATP stores and releases energy

Answers

Answer:

The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

This king once fell very ill-so ill thatnobody thought he could live. His sons were very much grieved at their father's sickness, and as they were walking together very mournfully inthe garden of the palace, a little old man met them and asked what was the matter. They told him that their father was very ill, and that theywere afraid nothing could save him. "I know what would," said the little old man; "it is the water of Life. If he could have a draught of it he wouldbe well again; but it is very hard to get." Then the eldest son said, "I will soon find it and he went to the sick king, and begged that he might go insearch of the water of Life, as it was the only thing that could save him. "No," said the king. " had rather die than place you in such great dangeras you must meet with in your journey." But he begged so hard that the king let him go; and the prince thought to himself, "If I bring my fatherthis water, he will make me sole heir to his kingdom."ResetNext20 Edmentum. All rights reserved
