Answers

Answer 1

Answer:

Its very easy here see we human being and animals are mutlicelluar organism We have different cells which form tissues and tissues forms organs and organs form human body

Each and every cells and tissues have their own work and functions to do

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?

Answers

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.

Answers

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.

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.

Answers

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?

Answers

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.

C

Answers

Answer:

None of the above

Explanation:

Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3

Answer:

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.

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.

Answers

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.
