The particle that always have positive charge is proton. The correct option is D.
What are protons?A proton is basically a subatomic particle found in every atom's nucleus. The particle has a positive electrical charge that is equal to and opposite to the electron's.
Protons are positively charged particles that have a mass of about 1 amu. These positively charged particles are found in the nucleus of the atom. Neutrons are electroneutral particles with the same mass as protons.
Electrons are negatively charged subatomic particles. Protons are subatomic particles that have a positive charge. The strong nuclear force holds protons together in the nucleus of an atom.
Thus, the correct option is D.

Which of the following describes the fluid mosaic model?
1. a phospholipid bilayer with various molecules embedded within and floating between the layers
2. all the liquid and solid components within a cell 's interior, excluding the nucleus
3. an explanation of how proteins embedded within the plasma membrane aid in cell functioning
4. the gel-like extracellular mix of proteins, polysaccharides, and other substances within tissues
Answer:
1. a phospholipid bilayer with various molecules embedded within and floating between the layers
Explanation:
The fluid mosaic model is best described as a phospholipid bilayer with various molecules embedded within and floating between the layers.
This is because this model talks about a phospholipid layer having protein and other molecules in it which aids in it being fluid. The fluid characteristic is what encourages floating between the layers.

Ice fishermen drill holes in ice covered lakes so they can fish in the cold winter months. The water beneath the layer of ice remains
liquid. If the ice sank to the bottom, the lake would freeze from the bottom to the surface. This would freeze all of the lake's organism.
Which property of water explains this occurrence?
A lower pH makes the water more acidic, resulting in the neutral ice floating
The bonds, between the water atoms, break expanding the ice molecules so that liquid water can fill the spaces in between the frozen water
molecules
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
The water's cohesive properties keeps the molecules close together, therefore, increasing the density ice.
Answer:
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
Explanation:
Water has awesome properties that distinguishes it among all other substances, many of which is attributed to its hydrogen bonding. Liquid water contains hydrogen bonds that holds tightly its molecules. However, when this liquid water freezes, the hydrogen bonds between its molecules break and expands. This creates space for the water molecules to occupy as it turns to its solid form (ice).
This is the case of this ice-covered lake. The ice, when it sinks, causes the liquid water beneath to freeze because the hydrogen bonds between the water molecules are being expanded enabling the molecules to occupy more space (volume) and make it less dense than liquid water (decreased density).
Answer:The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.

What stages of the water cycle where water moves downward from the force of gravity
Answer:
Precipitation, Surface Runoff and Infiltration process
Explanation:
There different stages of the water cycle where the water comes back on earth due to the gravitational force are as follows-
Rainfall/Precipitation- The water vapour in the cloud undergoes the process of condensation, it leads to the occurrence of rainfall, where the water comes freely over the ground surface from a certain height.
Surface Runoff- These refer to the flow of water rapidly along a steep slope, under the influence of gravity that eventually adds to the streams, lakes and rivers.
Infiltration process- This is the process where the water from the earth's surface percolates through the rocks and flows downward and eventually mixes with the groundwater.

In what direction and with how much not force will the satellite move?
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.
Answer: D
Explanation:
The net force with which the satellite move is 500 Newtons and 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.

Answer:
Ampicillin in a plate do as to help in maintaining ampicillin resistance plasmid in the growing medium
Explanation:
Ampicillin is an antibiotics that help to kill E.coli bacteria .
While growing bacteria in a plate or growing medium, it is important to add ampicillin to the plate so to maintain ampicillin resistance plasmid.
The absence of ampilicin, the bacteria will lose their resistance after they might have gone through some cell divisions and any bacteria that doesn't have resistance plasmid will be more vigorous than those that have and will outcompete them

4. Using a complete sentence, state what would most likely happen to the production of oxygen by duckweed plants if the intensity and duration of exposure to light were increased.
Answer:
See the answer below
Explanation:
If the intensity and duration of exposure to light are increased for a duckweed plant, the rate of photosynthesis would increase and this would lead to an increase in the amount of oxygen produced.
From the equation of photosynthesis:
[tex]6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2[/tex]
the more the rate of photosynthesis, the more the amount of oxygen produced. Also, an increase in the intensity of light generally increases the rate of photosynthesis (and oxygen production) provided that other reactants can catch up. The rate of photosynthesis would become limited by the reactant that is available in the lowest quantity.

What is the best example of a cyclic event?
a. the appearance of Halley’s comet every 76 years
b. a hurricane moving up the east coast an hitting Long Island
c. an earthquake near Washington DC
d. a tsunami striking the east coast of Japan
The correct answer is A. The appearance of Halley’s comet every 76 years.
Explanation:
Cyclic events follow a pattern of occurrence, this means they occur every certain time and can be predicted. This category includes natural phenomena such as weather patterns or the phases of the moon. In this context, the one that is an example of a cyclic event is Halley's comet (option A) because the appearance of this comet occurs every certain time (76 years) and this can be predicted, which are two key features of cyclic events. Also, others such as hurricanes, tsunamis, or earthquakes do not follow a precise cycle or cannot be precisely predicted.
Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you feel awake and alert. Scenario B: Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. Which article is more likely to have been peer reviewed? How do you know?
Answer:
The article read by Yuki
Explanation:
The article read by Yuki is more likely to have been peer-reviewed out of the two articles illustrated in the scenarios.
This is because magazine articles are usually written by staff writers or freelance journalists as opposed to professionals that are responsible for writing professional journals. Moreover, magazine articles are intended for general public reading and as such, are written in general, non-technical languages while professional articles are written in technical languages intended for scholarly use.
Articles in magazines are usually unstructured and hardly report scientific results unlike those in professional journals that require well-structured formats.
Consequently, articles in the Professional Journal of Medicine read by Yuki is more likely to be peer-reviewed than the article read by Carmen in Tasty Food magazine.
Answer:
