In a large artery, the external elastic membrane is the layer that lies between the tunica media and tunica externa.

The outermost tunica (layer) of a blood vessel, also known as the tunica adventitia (New Latin "additional coat"), is known as the tunica externa (New Latin "outer coat"). It surrounds the tunica media. It is mostly made of collagen and is supported in arteries by elastic lamina on the outside.

It is made out of the tunica intima (I), a straightened layer of endothelium; the tunica media (M), a layer of smooth muscle cells and elastic fibers (black in B); and the fibrous connective tissue known as the tunica adventitia (Ad).

Answer:

It is the bottom layer.

Explanation:

you would expect the marine organism to go extinct before it evolved because the deeper the layer, the older the fossil

The statement "When trying to determine whether a fossil is a human ancestor, we should always look for traits that make us human today" is False. It is because knowing what makes us human today is not always the most efficient method for determining what qualifies as a human ancestor.

Human ancestor refers to those species from which humans evolved. To decide whether a fossil is a human ancestor, one must search for traits that are characteristic of the features that are found in modern humans, and those that are not. The quest to locate the characteristics of a human ancestor is complicated by the fact that the features that distinguish humans from other creatures have evolved over time. Several of the morphological features discovered in fossils have been discovered in various hominin species or in other lineages within our family tree.

The evolution theory posits that living organisms have evolved over time from earlier and different forms. The theory of evolution through natural selection was first introduced by Charles Darwin.

He suggested that species that are more suited to their environment would survive and reproduce more effectively compared to other species that are less suited to their environment.

If you are walking down the riverbank, and a man is drowning, even if you don't know how to swim very well, you feel this urge that the right thing to do is to try to save that person. This is because humans are empathic beings, which means that we can feel the emotions of others. When we see someone in distress, we feel their pain and want to help in any way that we can.

The urge to save someone who is drowning is not necessarily driven by the theory of evolution. Instead, it is a result of our innate empathy, compassion, and the desire to help others. Helping others is an essential part of being human, and it is something that we do instinctively because we care about the well-being of others. Therefore, the idea that evolution would tell us to preserve our DNA by ignoring someone who is drowning is not accurate.

There will be no change observed in the mass of the model cell when the solution in the beaker has 0% concentration because movement of fluid takes place only when a concentration gradient is formed between the substances.

The movement of fluid from one place to another takes place when the concentration of fluid varies between two different substances. This takes place due to the concentration gradient according to which movement of particles will take place from areas of higher concentration to areas of lower concentration without use of external energy.

Since in the given problem, the solution in the beaker has 0% concentration, therefore it is considered as neutral which does not impact the overall concentration of the cell.

The synaptic site that is also known as a neuromuscular junction is indicated by option D. The neuromuscular junction is the area where a motor neuron's nerve fiber meets with a muscle fiber to trigger contraction.

The neuromuscular junction is the site where a motor neuron's nerve fiber meets with a muscle fiber to initiate a muscular contraction. The contact between the nerve and muscle fiber is established through a synapse or junction called the neuromuscular junction.

The neuron transmits an electrical signal known as an action potential along its nerve fiber. The action potential travels to the synaptic terminal, which is the end of the nerve fiber. The synaptic terminal contains tiny vesicles filled with a neurotransmitter substance known as acetylcholine.

Acetylcholine is released into the synaptic cleft when an action potential reaches the synaptic terminal. The neurotransmitter substance subsequently binds to receptors on the muscle fiber's plasma membrane, which stimulates the muscle fiber to contract. As a result, the neuromuscular junction is critical to muscular activity.

Glycolysis is a crucial metabolic pathway in which glucose is broken down into pyruvate, resulting in the production of a net yield of 4 ATP molecules for each molecule of glucose catabolized.

In glycolysis, each molecule of glucose that is catabolized gives a net yield of E) 4 molecules of ATP. Here's a step-by-step explanation of how this occurs in glycolysis:

1. Glycolysis is the first stage of cellular respiration and takes place in the cytoplasm of the cell. It involves the breakdown of one molecule of glucose (a six-carbon sugar) into two molecules of pyruvate (a three-carbon compound).

2. The process of glycolysis is divided into two phases: the energy investment phase and the energy payoff phase. During the energy investment phase, two ATP molecules are consumed to prepare the glucose molecule for subsequent reactions.

3. The energy payoff phase is where ATP molecules are generated. In this phase, the two three-carbon molecules produced earlier undergo a series of reactions, ultimately resulting in the production of four ATP molecules.

4. Since two ATP molecules were used up in the energy investment phase, the net yield of ATP molecules from glycolysis is four (4 ATP generated - 2 ATP consumed = 2 ATP net yield per three-carbon molecule).

5. However, as there are two three-carbon molecules produced from one glucose molecule, the total net yield for the entire process is 2 x 2 = 4 ATP molecules per glucose molecule.

In summary, glycolysis is a crucial metabolic pathway in which glucose is broken down into pyruvate, resulting in the production of a net yield of 4 ATP molecules for each molecule of glucose catabolized.

The mutation in the gene that encodes RNA polymerase so that it does not bind to the late gene promoter of bacteriophage T4 would have the effect that the bacteriophage T4 will not be able to undergo late gene transcription.

What is a mutation? A mutation is a process of change that happens naturally in DNA or genetic material. Mutations can be induced, which implies they're brought about by a presentation to natural factors, for example, synthetic substances, radiation, or high temperature, or can happen naturally.

What is RNA polymerase? RNA polymerase is an enzyme that assists with the production of RNA utilizing DNA as a layout. It adds RNA nucleotides in the 5'→3' direction, catalyzing phosphodiester bond formation between the 5' phosphate group of the first RNA nucleotide and the 3' hydroxyl group of the growing RNA chain.

In prokaryotes, RNA polymerase consists of a core enzyme and a sigma factor. It is responsible for initiating transcription at specific sites and directing RNA polymerase to the promoter. It consists of four subunits: α, β, β′, and ω, as well as the sigma factor, which helps to stabilize the core enzyme-promoter complex.

What happens if the RNA polymerase doesn't bind with the promoter? If RNA polymerase cannot bind to the promoter, transcription will not occur. The RNA polymerase enzyme cannot bind to the DNA promoter sequence on its own.

Instead, it is necessary for specific DNA-binding proteins, known as transcription factors, to bind to the promoter and recruit RNA polymerase to the site in order to initiate transcription.

An element that has 53 electrons will have 53 protons as well.

This is because in an electrically neutral atom, the number of electrons is equal to the number of protons in the nucleus. An element's atomic number corresponds to the number of protons in the element's nucleus. For example, if the atomic number of an element is 6, it will have six protons in its nucleus.In a neutral atom, the number of protons is equivalent to the number of electrons, which implies that a neutral atom has no overall charge. When an atom gains or loses an electron, it becomes charged and is now referred to as an ion. The overall charge on the ion will be negative if it gains electrons, and it will be positive if it loses electrons. In conclusion, an element with 53 electrons will have 53 protons because of the principle of electric neutrality.
