Answer:
4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.
Explanation:
It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.
Let the total number employees be e.
Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.
e < 24
Multiply 4 both sides.
ex 4 < 24×4
3e < 96
Divide both sides by 3.
e < 32
Therefore the value of e is less than 32.
In a number line as we approach towards left the the value of integers decreases.
Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.
Since 32 is not included in the solution set, therefore there is an open circle on 32.

When the stimulus voltage is increased, _______. When the stimulus voltage is increased, _______. sodium permeability into the cell decreases sodium permeability into the cell increases to overcome the potassium exiting a greater-than-threshold depolarization results a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Answer:
a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.
Explanation:
The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.
When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.
Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.
The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.

Mrs. Blakely's chemistry class is acting out chemical reactions on a dance
floor. The whole class gets on the dance floor and moves around like
molecules of air in a beaker. What could the students do to model a condition
that would decrease the rate of the reaction?
A. Have the people on the dance floor choose a partner.
B. Have more people get on the dance floor.
C. Have some people get off the dance floor.
D. Have the people on the dance floor move faster.
Answer:
it's either C or D
The students simulate a situation that might cause the reaction rate to decrease, such as having some people leave the dance floor while others move more quickly. So, the correct options are C and D.
What is Reaction rate?The pace at which a chemical reaction occurs is known as the rate of the reaction. It is proportional to the rise in product concentration per unit time and the fall in reactant concentration per unit time. Response times can differ wildly.
For instance, because it happens quickly, wood burning has a fast reaction rate, whereas iron rusting has a low rate of the reaction because it happens gradually.
For the aforementioned illustration, the students act out a scenario that can result in a slower reaction time, such as having some participants leave the dance floor whereas others move more swiftly.
Therefore, the correct options are C and D.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap. What process formed the water droplets in Scott's model?
Answer:
The correct answer is - condensation.
Explanation:
When humid air comes in contact with the cold surface and we get the water in form of droplets, it is called condensation. In other words, condensation is the change of water vapor to the water exactly opposite of the evaporation process.
In the given experiment of Scott where droplets are collected on the plastic surface which simply illustrates the phenomenon of condensation as the water evaporated due to the heat of the lamp and condensed on the surface of plastic wrap.
Answer:
C
Explanation:

A mouse had a gene sequence of GTT coding for leucine, an amino acid. mutation in this gene led to the formation of GTG. However, the amino acid formed was leucine, despite the mutation. This is a mutation for the mouse
Answer:
1- substitution.
2- neutral.
Explanation:
The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.
A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.
Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.

2- neutral.

The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?
4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year
Answer:
4 frogs per year is the answer
In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).
Formula used: dN/dT= rN{1-N/K}
Given: k= 840 frogs
N= 212, r= 1 year
To find: r=?
Solution:
putting value in equation:
dN/dT= rN{1-N/K}
dN/dT = 1 x 212 {1-212/840}
so, dN/dT= 158.57 ( approx)
Final answer: The correct option is (c)
158 frogs per year
Thus, we can conclude that 158 frogs per year will be the population of frogs.

In the early days of the solar system, many planetesimals orbited the Sun. The theory has it that one large planetesimal the size of Mars struck a glancing blow to the molten Earth. How did this event contribute to the formation of the Moon?
Answer:
This event led to the breaking away of a part of earth and the part was held on by earth’s gravity and this part became the moon.
Explanation:
The formation of moon was after the formation of the earth. In the initial years of the formation of earth it was affected by several asteroid hits and comets. Small planets referred to as planetesimals also kept continuously affecting the earth. Before 4.5 billion years ago a planetesimal which was about the size of Mars hit earth.
This hit led to the breaking away of a part of earth. The part which was sent to space by the hit was caught by the gravity of the earth and the part started orbiting around the earth. The similarity of the rocks in moon to that of earth is attributed to the fact that moon was actually formed from earth.
The moon and earth keeps influencing each other. The moon’s effect reduced the speed of earth’s rotation and the moon keeps moving away from the earth due to the influence of earth.
Answer:Molten rock broke off from Earth following the impact. The rock coalesced (gathered) into a ball, which formed the Moon.

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?
Answer:
The biology branch deals with the relations between and physical environment of organisms.
Explanation:
The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.
In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.
