Red blood cells and the endothelial cells that line blood vessels do not interact, hence option b is correct. This is how vascular endothelial cells interact with one another.
The most prevalent form of cell in blood are red blood cells, commonly known as endothelial cells. White blood cells, platelets, and plasma are further important blood constituents.
the kind of endothelial cells that coats lymphatic and red blood cells ; these cells are typically squamous (flattened) and form sheets that are one layer thick. Embryonic mesenchyme cells give rise to endothelial cells. The term "endothelium" refers to a layer of endothelial cells.

While the sympathetic nervous system prepares the body to respond to stressful situations, the parasympathetic nervous system takes it back to its normal relaxed state once the stressful factor is over. 1) sympathetic nervous system 2) parasympathetic nervous system.
How does the body respond to stressful situations?When facing stressful situations, like a dog attack, the body responds through the sympathetic nervous system (SNS) which prepares the organism to escape from that situation.
Let us remember that the sympathetic nervous system and the parasympathetic nervous system compose the autonomous nervous system and have opposite effects on the organism.
During stressful moment, the sympathetic nervous system, SNS, produce an increase in heart-biting frequency and strength, blood pressure, overstimulate respiration, and dilatates respiratory tracts. The organism is alert and ready to escape.
When the affecting factor disappears, the parasympathetic nervous system is activated and the body recovers its balanced and relaxed state by reducing blood pressure and respiratory and cardiac frequency.
Alma is walking in a park. Suddenly, a wild dog charges toward her. Alma is frightened. The 1) sympathetic nervous system starts to respond by increasing her heart rate and dilating her pupils.

Note that the mating calls of the two species are similar in areas where only one of the two species is present, but markedly different in areas where both species live. State an explanation for this.
It explains the exclusion principle, that two species can't coexist if they occupy exactly the same niche.
The aggressive exclusion precept tells us that two species cannot have precisely an equal area of interest in habitat and stably coexist. this is due to the fact species with equal niches also have the same desires, which means that they might compete for exactly equal sources.
Begin superscript, 1, end superscript. every species fits into an ecological network in its own special manner and has its personal tolerable levels for lots of environmental elements.

Nicotine binds to acetylcholine receptors at the synaptic cleft. Which is a likely effect of nicotine?.
Answer:nicio
Explanation:
Nicotine binds to acetylcholine receptors to the synaptic cleft. This will enable Na⁺ flux into the postsynaptic neuron in the absence of a presynaptic action potential.
What is Synaptic cleft?Synaptic cleft is the space between two neurons across which the impulse is transmitted by a neurotransmitter. The neuron which transmits the signals are known as presynaptic neurons and the neurons which receives the signal are known as postsynaptic neurons.
Nicotine similar to Acetylcholine (ACh), is a nicotinic receptor agonist. The binding of nicotine and ACh to the nicotinic receptors on the plasma membrane cause a conformational change that either opens or closes the ion channels of the receptors, thereby changing the receptors' functional state.

What is a macromolecule?
A macromolecule, such as a protein or nucleic acid, is a very big molecule crucial to biophysical processes. It is made up of many atoms that are covalently bound. There are numerous macromolecules that are polymers of monomers, or smaller molecules.
Since macromolecules are composed of repeated monomer subunits, they are sometimes referred to as polymers, which means "many" units. Carbohydrates, lipids, nucleic acids, and proteins are examples of the four biological macromolecules of life. Protein makes up a sizable portion of our bodies' dry weight or the weight that is not water, which makes up a sizable portion of the total. Protein makes up a very high percentage of the substance in our organs (including the skin), glands, and body fluids. For example, our bones are roughly one-fourth protein. The entire animal kingdom, including the animals we feed and the bacteria that invade our bodies, is mostly constituted of protein, not just humans.

2. The answer is A ( the cell will shrivel).
3. The answer is C.
4. The answer is C the cell membrane.
Explanation:
1. Osmosis, the process where water moves from less salty to saltier compartments, makes it so that freshwater fish never drink water! Instead, they absorb water through their gills because their bodies are saltier than the water around them
2. A hypertonic solution is type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane , but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.
3. The mitochondria is THE POWERHOUSE OF THE CELL.
4. Well the cell membrane contains the axons of a cell ( or at least in animal cells), so I would have to say the answer is C.
What can be used to determine the relative age of two rocks? question 13 options: vertical position the presence of unconformities radioactive dating of each layer relative age cannot be determined
The relative age of two rocks can be determined by: radioactive dating of each layer.
Radioactive dating is the method of determining the age of rocks or minerals using the radioactive substances. The method is very useful for determining the age of igneous and metamorphic rocks whose dating cannot be done using any other method.
Rocks are the solid aggregates of minerals, soil and many other components. According to their composition rocks can be of three types: Igneous, Sedimentary and Metamorphic. Igneous rocks are formed from molten rocks. Sedimentary rocks are formed by the layers of sand, silt and dead plants. Metamorphic rocks are formed from other rocks subjected to heat and pressure.

The two medial and sidelong collateral tendons work together to permit your knee to move accurately, whereas the front and back cruciate tendons limit it from moving within the off-base heading.

Cruciate tendons are the interior of your knee joint and interface your femur to your tibia. They cross each other to form an X.
The cruciate is the foremost vital knee tendon in giving soundness to the knee. There are two cruciate tendons, the front (ACL) and the back (PCL).

What is a consensus sequence?A consensus sequence is a nucleotide DNA sequence of an organism that contains the most common nucleotides at each position, which indicates that the sequence derives from a common origin.
A consensus sequence may be very useful to determine if an organism is part of the same lineage group and or taxonomic group, and common genes encoded by a group such as a tubulin gene can be used to find significant differences in a sequence alignment.

Bi-somatic RNA Ribosomal ribonucleic acid (rRNA), which is the RNA component of the ribosome in molecular biology, is necessary for protein synthesis in all living things. It makes up the majority of the ribosome, which is made up of roughly 60% rRNA and 40% protein by weight.
The largest nuclear organelle, the nucleolus, is where ribosomal subunit biogenesis mostly occurs in eukaryotic cells. It forms specialized chromosomal structures called nucleolar organizing regions (NORs), which are the locations of ribosomal DNA transcription. These NORs are formed around arrays of ribosomal DNA genes.
