Answer:
The organic compounds in coal are composed of the elements carbon, hydrogen, oxygen, nitrogen, sulfur, and trace amounts of a variety of other elements
Coal is a mixture of organic compounds and minerals formed from ancient plant material, primarily composed of carbon, hydrogen, and impurities like sulfur and nitrogen.
Coal is a mixture of organic compounds and minerals, resulting from the decomposition of ancient plant material over millions of years. It primarily consists of carbon, hydrogen, oxygen, nitrogen, and sulfur. Carbon, the dominant organic compound, makes up a substantial part of coal's composition, with hydrogen and oxygen occurring in lesser amounts.
Nitrogen and sulfur are present as impurities, in the form of organic compounds and mineral components. Coal also contains inorganic minerals like quartz, clay, and pyrite, contributing to its ash content. Trace elements, such as mercury, arsenic, and lead, are present in low concentrations. The exact composition varies based on coal type and location, influencing its energy content and environmental impacts.

Which of the following is an extremely dense form of connective tissue?
Answer:
the breast tissue
Explanation:
Tendons and Ligaments are the extremely dense form of connective tissue.
What are dense connective tissues?Dense connective tissue is also known as dense fibrous tissue which is a form of connective tissue composed mostly of fibers. These fibers are made of type I collagen which are rows of fibroblasts, the fiber-forming cells that make up the fibers, filled in between the collagen strands.
Tendons and ligaments are strong, rope-like structures which is formed by dense connective tissue where tendons connect skeletal muscles to bones, while ligaments connect bones at joints.
Ligaments have more elastic fibers which are more extensible than tendons. This connective tissue is found in the lower layers of the skin known as Dermis, where it is structured in sheets.
Thus, Tendons and Ligaments are the extremely dense form of connective tissue.

Answer:
Humans require food substances to supply the components necessary to build tissues, to repair tissues as they wear out and die, to keep the body in good working condition, and to supply fuel for energy. For good nutrition a person should eat a well-balanced diet, that is, one that provides an adequate amount of each of the classes of nutrients each day.
Explanation:
Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea
Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)
Explanation:
Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.
What is the greenhouse effect?
Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.
More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.
A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.
Therefore the correct option is D.

2. Which specific cytoskeletal element is most susceptible to mitotic inhibitors?
Answer:
microtubules
Explanation:
Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.
What is Microtubules?The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.
They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.
Microtubules, which typically consist of 13 linear protofilaments arranged around a hollow core, are created when tubulin dimers polymerize to generate them. The head-to-tail arrays of tubulin dimers that make up the protofilaments are organized in parallel.
Therefore, Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

Explanation:
Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it.
