Epinephrine triggers a direct signal transduction pathway.
I know this because when epinephrine binds to it's receptor example on a muscle cell,this is known as a type of G protein -coupled receptor,signal transduction cascade is triggered and this involves the production of a second messenger molecule cyclic AMP(cAMP).
Epinephrine also know as Adrenaline or sus-phrine.
It is a vasoconstrictor,broncho dilator and a sympathetic stimulant.
It constricts the peripheral abdominal organs as well as a stimulating the heart beat thereby raising the blood pressure,it also relaxes the spasms of the bronchial muscles thereby promoting ventilation of the lungs.

Describe the net movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water, which contains no solutes.
a. There will be no movement of water.
b. Water will move into the bag.
c. Water will move into the beaker.
d. There will be no net movement of water.
Answer:
b
Explanation:
The correct answer would be that water will move into the bag.
The 0.2 M sucrose solution in the dialysis bad has a lesser water potential when compared to the distilled water that has no solutes. By law, water moves from the region of higher water potential to the region of lower water potential. The dialysis bag will, hence, act as a semi-permeable membrane and allow water into the bad from the surrounding distilled water.
The correct option is b.

In the Colorado mountains, three species of bumble bees live in the same habitat. Each species has a different proboscis length: short, medium, or long. Each visits nectar-producing plants that match its proboscis length. This situation suggests that natural selection in the three bumble bee species has resulted in
Answer:
resource partitioning
Explanation:
Resource partitioning can be defined as the division of limited resources that enables species to avoid competition when they live in the same habitat. Moreover, interspecific competition is defined as the competition for limited resources among individuals of different species. In a given environment, species can be competing for essentially the same limiting resources. In the case of the bumblebees, the competence is reflected by differences based on the length of the proboscis (competence for the food), thereby resource partitioning enables species to coexist with one another.

What are the atomic masses of
protons, neutrons, and electrons?
Answer:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Explanation:
The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.
Thus, Electrons circle the nucleus, having a mass of about 0 amu, and a charge of -1.
Atomic mass of a proton: A proton's atomic mass is about equal to 1.007276 atomic mass units (u), or 1.007276 amu.
Neutron: A neutron has a slightly larger atomic mass than a proton. About 1.008665 u or 1.008665 amu is what it is. Electron: Compared to a proton or neutron, an electron has a substantially lower mass. An electron has a mass of roughly 0.00054858 u or 0.00054858 amu.
Thus, The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.

Describe an example of a relationship between a cell organelle and a task a cell must perform
Answer: These organelles are like the organs in a human and they help the cell stay alive. Each organelle has its own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a Golgi apparatus that packages and distributes proteins.
An example of a relationship between a cell organelle and a task a cell must perform is: Mitochondria and transformation of energy by a cell.
A cell refers to the fundamental functional and smallest unit of life in all living organisms.
According to their cell type, all living organisms are mainly divided into two (2) main groups and these include;
Unicellular organisms. Multicellular organisms.Cell organelles can be defined as the organs (workers) that are saddled with the responsibility of performing various tasks or functions for the survival of a living organism. Some of the cell organelles found in living organisms include the following:
Nucleus.Cytoplasm.Cell membrane.Golgi apparatus.Mitochondria.Mitochondria is usually referred to as the power house of a cell because it is mainly responsible for the provision and transformation of all of the energy required by living organisms.

One primer attaches to the __ end of the gene region on the 5' to 3' strand, another to the ___ end of the gene region of the 3' to 5' strand. This was maybe not explicit in the video. 3’ and 5’ refer to the orientation of the DNA strand. The 3’ end is the end that has the OH group used for adding new nucleotides. The 5’ end is the end where a phosphate sticks out from the ribose. The two strands that make up the DNA molecule run anti parallel to each other. Synthesis is always in the 5’ to 3’ direction (because that is where new nucleotides attach), and the template strand is read 3’ to 5’ (because it runs antiparallel).
Answer:
Explanation:
This question is incomplete however during DNA amplification using polymerase chain reaction, the two primers attach to each DNA strand at the 3' end.
Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.

Two male sea horses fight to win over a female.
Several elk travel together to find and share water.
Different kinds of garden plants take in water from the soil.
Answer:
I think its B if I'm wrong I'm sorry
Two male sea horses fight to win over a female describes the competition within a population. So, the correct option is B.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms always consumes the available resource which reduces the quantity.
Competition is defined as the fight between different organisms by limited resources. Some examples of interspecific competition between lions and leopards that vie for the same prey and interspecific competition between rice fields with weeds growing in the field, two male seahorses fighting to win over a female.

Water has a variety of unique properties, including a low melting point, ability to dissolve other substances, and strong adhesion and cohesion. Which statement is MOST useful for explaining the unique properties of water? A. Water molecules are nonpolar, so a very minimal electrical force attracts them to one another. B. Water molecules may sometimes gain or lose an oxygen atom to become ions, which are held together by ionic bonds. C. Water molecules are held together by hydrogen bonds, which are attractive forces stronger than ionic bonds. D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds.
Answer:
D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds
Explanation:
Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question. This unique properties can be attributed to the HYDROGEN BONDING that holds the molecules of water together.
However, the hydrogen bonding of water molecules is an attractive force that is quite WEAKER than ionic or covalent bonds but it holds water molecules tightly to one another.
