Epinephrine enters the cell after it binds to the receptor. Yes, this statement is true.
What are the functions of epinephrine?
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions. It appears as a white microcrystalline granule.
Epinephrine injection is used for emergency treatment of severe allergic reactions (including anaphylaxis) to insect bites or stings, medicines, foods, or other substances.
Through its action on alpha-1 receptors, epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction.

what is the cause and effect of stop codone mutation?
Answer:
Nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Use the image to answer the question.
The image shows a food chain. An arrow points from grass to a grasshopper. An arrow points from the grasshopper to a lizard. An arrow points from the lizard to a hawk. An arrow points from the hawk to a fox.
What would happen if the number of grasshoppers in this food chain decreased?
A.
The amount of grass would increase.
B.
The number of lizards would increase.
C.
The amount of grass would decrease.
D.
The number of hawks would increase.
Answer:
a, the amount of grass would increase
Explanation:
if the grasshopper is the one in this diagram eating the grass, and suddenly there were fewer grasshoppers to do that, the grass would increase because more of it can grow without being eaten
Which is not a likely economic tool to address environmental issues?
Emissions fees and taxes
Responsibility for a product from production to disposal
Small business liability relief
Defunding government regulation
Explanation:
Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports
Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS

Answer:
Mouth
Explanation:
The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?
The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

Explain the idea of "survival of the fittest" with regards to a population of beavers in a lake in which some have large incisor teeth and others have small incisor teeth.
The study of gradual change is called evolution.
The correct answer is mentioned below.
What is evolution?Evolution is a change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.According to the question,
If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will then be able to reproduce therefore passing down the gene with larger incisor teeth.

Alejandro wants to find the speed of his car in meters per second. His car traveled 50 cm. It took 5 seconds to travel 50 cm. How fast did his car go?
Answer:
0.1m/s
Explanation:
Speed can be calculated using the formula;
Speed (m/s) = distance (m) ÷ time (s)
According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.
However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.
100cm = 1m
50cm = 50/100
= 0.5metres.
Speed = 0.5/5
Speed = 0.1m/s.
The car travels as fast as 0.1m/s.
