The net force is 0 N, so the satellite will not move.

The net force is to the right at 1500 N.

The net is to the left at 1000 N.

The net is to the left at 500 N.

The net force with which the satellite move is 500 Newtonsand the satellite moves in the left direction. Thus, the correct option is D.

### What is the net force?

The net force on an object can be defined as the combined effect of the sum of all the forces such as pushing and pulling forces which are actually acting on the object. If all the forces which are pushing or pulling on an object are not balanced, then in this case a net force acts on that object which then makes the object to accelerate in the direction of the net force applied.

Net force = Sum of all the applied forces

Since, here the forces applied are in different directions.

Net force = 1000 N (towards left) - 500 N (towards right)

Net force = 500 N (towards left)

The net force has a magnitude of 500 Newtons and it is in the left direction because 1000 N is more than 500 N.

Therefore, the correct option is D.

Explanation:

Sigfried is a science student who develops the following hypothesis: If ants select blue sugar over red sugar, then ants prefer the color blue because it is more soothing than red. What is wrong with Sigfried’s hypothesis

It is not an issue of color, but rather of sugar content that causes the ants to choose the blue sugar over the red sugar. Because the blue sugar contains more sugar than the redsugar, the ants preferred it.

### What is sugar?

All sweet carbohydrates can be referred to as sugar, however the phrase is most frequently used to refer to table sugar, also known as sucrose, or a “double sugar.” Carbohydrates are converted by the body into easily absorbed simple sugars like glucose. There are numerous varieties of sugar.

The body uses sugars and starches from carbs to feed the brain with glucose and give the rest of the body's cells energy.

Most plants have sugars in their tissues. Honey and fruit are plentiful natural sources of simple sugars.

Sugarcane and sugar beet are particularly high in sucrose concentration, making them perfect for effective commercial extraction to produce refined sugar.

Therefore, blue sugar contains more sugar than the red sugar

Explanation:

The ants choosing the blue sugar over the red sugar isn't a matter of color, but it'd a matter of sugar content.

The ants chose the blue sugar because it has more sugar content than the red sugar.

1. What is the equation for the equilibrium constant, Keq, for the following general reaction: aA + bB → cC + dD Define each term in the equation. 2. What is the actual free energy change of the reaction above? Again, define each term in the equation. Express this equation in terms of mass action Q
3. What is the standard free energy change of the reaction above? Again, define each term.

Explanation:

From the reaction ; aA + bB → cC + dD

1) Keq = equilibrium constant = [A]^a [B]^b / [C]^c [D]^d

where [A] = [B] = [C] = [D] are the concentrations of reactants A, B, C and D respectively.

2) What is the actual free energy change of the reaction above? ;

• ΔG is the differences between the sum of the free energies of the product and the reactant.
• Mathematically; ΔG = (cΔGC + dΔGD) - ( aΔGA + bΔGB)
• ΔG, in terms of reaction quotient ; ΔG = ΔG(standard) + RT lnQ

where R = gas constant and T = temperature.

3) What is the standard free energy change of the reaction above;

• ΔG(Reaction) = Summation ΔGf(products) - summation ΔGf(reactants)
• where summation ΔGf = standard free energy of formation

Fatima suffered a brain injury and is having difficulty understanding spoken language. Which area of her brain is most likely to have beendamaged?
O Broca's area
Wernicke's area
Motor cortex
Cerebellum

Wernicke's area is most likely to have been damaged in Fatima's case.

### Explanation:

The area of Fatima's brain most likely to have been damaged is Wernicke's area. Wernicke's area is responsible for the comprehension and production of spoken and written language. Damage to this area can result in difficulties understanding spoken language, as in Fatima's case. This area is located in the left hemisphere of the brain, near the auditory cortex.

What stages of replication do both cycles have in common? Describe the virion action at each of these stages.

The stages of replication is  Attachment, Penetration and Replication

The following information should be considered:

• A bacteriophage means the virus that attacks bacterial cells.
• The lytic and lysogenic cycles comrpise of two methods of viral replication.
• In the lytic cycle, the virions generated are released from the host cell while on the other hand in the lysogenic cycle, viral nucleic material are existed into host nucleic material and also they are copied to daughter cells at the time when the host cell reproduces.

The common steps in both cycles are given below:

1. Attachment – in this step, the bacteriophage attaches itself to the host surface cell to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell via penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Attachment, Penetration and Replication

Explanation:

A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:

1  Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.

2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.

3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

These "abiotic ingredients" are the inorganic chemicals in Earth's early atmosphere (water, methane, hydrogen, carbon dioxide). Heat, lighting and lack of oxygen caused these inorganic chemicals to react with each other and form simple organic chemicals containing both hydrogen and carbon.true or false
