The neurotransmitter that has widespread effects on a person's attention and emotional state is norepinephrine

Norepinephrine is a neurotransmitter that is produced in the brainstem and acts as a hormone in the sympathetic nervous system. It plays a key role in regulating attention, mood, and arousal, and is involved in the body's "fight or flight" response to stress. Norepinephrine works by binding to adrenergic receptors in the brain and peripheral nervous system, which can lead to increased heart rate, blood pressure, and breathing, as well as heightened alertness, motivation, and mood. Low levels of norepinephrine have been linked to symptoms of depression, while high levels have been associated with anxiety and stress.

Other neurotransmitters, such as dopamine and serotonin, also play important roles in regulating mood and attention, but norepinephrine is unique in its widespread effects on the sympathetic nervous system and its ability to modulate multiple brain regions involved in emotional processing and cognitive control.

The connective tissue layer that surrounds each muscle fiber and electrically isolates it is called the endomysium.

The endomysium is a delicate layer of connective tissue that surrounds individual muscle fibers or muscle cells. It consists of collagen and reticular fibers and separates each muscle fiber from its neighboring fibers, providing electrical insulation between them. This insulation prevents the electrical impulses generated within one muscle fiber from spreading to adjacent fibers.

In addition to its electrical isolation function, the endomysium also provides support, nutrients, and oxygen to the muscle fiber, and facilitates the exchange of waste products.

It is one of the layers of connective tissue, along with the perimysium and epimysium, that contribute to the overall structure and organization of skeletal muscle.

Answer:

This is an interesting thought experiment.

I am going to assume we are still human with similar heads/faces and digestive systems to what we have currently.

It would depend on what kind of tooth you picked.

With all incisor teeth we would be unable to grind up tough food and would have to swallow everything just as is on the end of the fork when you put it in your mouth (assuming you eat with a fork).

With all molar teeth we would not be able to bite through food very well. So cutting up food before you put in your mouth would become important.

The next issues are digestion. Chewing and breaking the food into small pieces is important in freeing up nutrients from food and making it digestable.

With a good knife and and a blender we could likely get around the digestive issues associated with not chewing our food or trying to eat large mouth fulls of food at once.

If you had a good sharp stone and another grinding pair of stones you could also achieve the desired consistency for food to provide energy and nutrients.

If you didn’t have tools it would be very hard get enough good food into your body. People still starve in 2017- there would be plenty more staving if you had to eat like this.

I also do not think that we would be able to produce speech as we do currently. We still would be able to speak but the sounds would be different.

The face would change. Particularly if we had molars everywhere.

Interesting idea. This would likely be evolutionary difficult/impossible.

Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.

Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.

The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.

X chromosomes will be in the other cell (polar body) at the end of meiosis-I.

All four of the meiotic products will have defective chromosomes if Non-disjunction occurs in meiosis I. There will be two copies of the chromosome involved in the non-disjunction event in two of the four meiotic products, and there won't be any copies of it in two of the four meiotic products.

Nondisjunction is the incorrect disjoining of homologous chromosomes during meiosis. Gametes with more or fewer chromosomes than typical ones are produced as a result of this. The person may therefore experience Turner syndrome.

Sedimentary rocks are formed by the fragments of other rocks. Your answer would be accumulation of eroded rocks.

Hunter-gatherers didn't store food for difficult seasons primarily because they were nomadic and did not have the means to carry or preserve large amounts of food. Additionally, they had not yet invented air- and water-tight containers for long-term storage.

Hunter-gatherer societies were characterized by a nomadic lifestyle, moving from one location to another in search of food resources. Their survival relied on hunting animals and gathering fruits, nuts, and other edible plants from the environment. Due to their mobility, storing large quantities of food for extended periods became impractical. It would have been challenging for them to carry heavy loads of food while constantly moving to new areas.

Furthermore, the invention of air- and water-tight containers, such as pottery or specialized storage vessels, came much later in human history. Without these containers, it would have been difficult to preserve food for long periods without spoilage. The lack of suitable storage options limited the ability of hunter-gatherers to store significant quantities of food.

Instead of storing food, hunter-gatherers relied on immediate consumption or utilized techniques like drying, smoking, or preserving food through natural means to extend its shelf life for shorter periods. Their lifestyle and resource availability dictated their need for immediate sustenance rather than long-term storage. It was only with the advent of agriculture and settled lifestyles that humans developed the capability to store surplus food for future use.

Retroviruses, such as HIV, are an exception to the central dogma as they reverse transcribe their RNA genome into DNA, challenging the flow of genetic information.

The central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein. While most viruses adhere to this central dogma, there are exceptions. The retrovirus is one such exception.

Retroviruses, like HIV, possess RNA as their genetic material, but they are unique in their ability to reverse transcribe their RNA genome into DNA. This DNA is then integrated into the host cell's genome, where it can be transcribed into RNA and translated into proteins.

This process involves the reverse transcriptase enzyme. Retroviruses essentially reverse the flow of information from RNA to DNA, challenging the central dogma.

In contrast, DNA viruses and RNA viruses generally follow the central dogma, with DNA viruses using DNA as their genetic material and RNA viruses using RNA to directly encode proteins without reverse transcription.

Animals make up 2 Gt of Carbon of the total biomass on Earth. 50 percent of this total biomass is made up of Arthropods (insects, arachnids or spiders, crustaceans, and myriapods such as centipedes, and millipedes). Arthropods make up 50 percent of the total biomass of animals on Earth because they are highly diverse, adaptable, and play crucial roles in ecosystems.

With over one million known species, arthropods represent the largest phylum in the animal kingdom. Their exoskeletons provide protection and support, allowing them to inhabit various environments, including terrestrial, aquatic, and aerial habitats. The flow of energy between arthropods and their energy sources is also an essential factor contributing to their high biomass. Most arthropods are primary consumers, feeding on plants or detritus, and converting solar energy stored in plants into a usable form for higher trophic levels, this position in the food chain allows arthropods to efficiently utilize energy and support their large populations.

Furthermore, arthropods are critical for ecosystem functions such as pollination, decomposition, and pest control, making them indispensable for maintaining ecological balance. Their ability to rapidly reproduce and adapt to changing conditions also contributes to their success and large biomass. In summary, arthropods make up 50 percent of the total biomass of animals on Earth due to their diversity, adaptability, crucial roles in ecosystems, and efficient energy use. Their presence ensures the stability and health of various ecosystems, and their biomass reflects their importance in the natural world.
