List 3 examples of the microscopic properties of hair.
The medulla, the cortex's coloration, and the kinds of scales that cover the outside.
What are microscopic properties?Microscopic properties are defined as the characteristics of the atoms and molecules that make up the majority of the substance.
It can also be defined as the conduct of a considerably smaller sample of matter, such as an atom or molecule
A macroscopic system's characteristics include pressure, temperature, density, volume, viscosity, resistance, liquid surface tension, and more.
All microscopic organisms those too small to be seen without a microscope include skin cells, bacteria, and some varieties of algae. In order to describe anything that is too small for the human eye, use the term microscopic.
Three macroscopic features are length, color, and curliness. The medulla pattern, cortical coloring, and cuticle scale kinds are examples of microscopic features.
Thus, the medulla, the cortex's coloration, and the kinds of scales that cover the outside.

Study an ecosystem of your choice such as a meadow, a patch of forest, a garden , or an area of wetland. (If you cannot do this physically, do so virtually by reading about an ecosystem online. Determine and list five major plant species and five major animal species in your ecosystem. Write hypotheses about which of these species, if any, are indicator species. Which of them, if any, are keystone species
Answer:
In a wetland ecosystem:
1- Indicator species: turtles
2- Keynote species: freshwater crayfish
Explanation:
A wetland is an ecosystem either covered with water or saturated with water. Examples of plants living in wetland ecosystems include water lilies lotus, trees (e.g., swamp she-oak), mosquito fern, eelgrass (Vallisnaria spiralis), etc. Examples of animals living in wetlands include dragonflies, mosquitoes, alligators, salamanders, snakes, turtles, grouse, plover, etc. Alligators and freshwater crayfish can be considered keystone species because they are fundamental and their presence defines wetland ecosystems (without these species, wetlands would be dramatically impacted). Moreover, turtles can be considered indicator species because their abundance and distribution in a wetland is an indicator of environmental conditions. These animals (turtles) carry around different organisms (e.g., algae) that are eaten by other species (e.g., fish), and thus contribute to the homeostasis of the ecosystem.

The mitochondria of a cell is the site for which two cellular processes?
A. The krebs cycle and the electron transport chain
B. the light reactions and the krebs cycle
C. the calvin cycle and the electron transport chain
D. the krebs cycle and the calvin cycle
Answer:
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.The mitochondria of a cell is the site for the krebs cycle and the electron transport chain. Thus, option A is correct.
What is RNA?
Full form of RNA is ribonucleic acid and it is a nucleic acid which is found in almost all cells that are living and RNA is mostly similar to DNA but there is one difference between RNA and DNA and the difference is that RNA is single stranded but DNA is double stranded.
The RNA's backbone is made up of phosphate group which is arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
The main function of mRNA is it work as immediater between protein and DNA which is utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA is to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
Therefore,The mitochondria of a cell is the site for the procedure of krebs cycle and the electron transport chain. Thus, option A is correct.

Which best explains why metal cooking utensils often have plastic coating on their handles?
O Plastic melts less easily and lasts longer than metal.
O Plastic reduces the transfer of thermal energy to hands holding the utensils.
O Plastic molds more easily into shapes like long, thin handles.
O Plastic increases the rate of conduction from the utensil to the food.
tìm
Answer:
B) Plastic reduces the transfer of thermal energy two hands holding the utensil.
Explanation:
plastic is a good insulator which means it's prevent energy, in this case thermal energy, from conducting into the person holding it. Metal is a very good conductor which is why you wouldn't want it to touch your hand while you're cooking.

List the three principal hormones that regulate glucose metabolism. Explain the effects these molecules have on carbohydrate metabolism
Answer:
The three hormones are insulin, glucagon, and GIP and GLP-1.
Explanation:
After the ingestion of carbohydrates, insulin increases in the blood generating peaks in blood glucose, therefore the hormone that will increase is insulin to lower blood glucose, promoting the entry of this monosaccharide into the cells.
Different from the moments when the person enters into physical activity, and blood glucose is low, therefore glucagon is activated and seeks to remove the energy reserves from the interior of the cell.

Answer:
How does biology change the way we think about life? - If plants didn’t produce their own food, you wouldn’t have anything to eat. So the next time you sit down to eat, you can thank the process of photosynthesis for your food.
Why is agriculture equally important to the other sciences? - Early farmers improved their crop production by inventing the first gardening tools. Today, farmers improve crop production through the use of Global Positioning Systems aka GPS. Agriculture is just as important, we need all of the new and old sciences.

______can be made from the science experiment called primordial soup
Answer:
Miller, along with his colleague Harold Urey, used a sparking device to mimic a lightning storm on early Earth. Their experiment produced a brown broth rich in amino acids, the building blocks of proteins. ... Instead, the mix created a colorless brew, containing few amino acids
Explanation:Oparin and Haldane thought that with the mix of gases in the atmosphere and the energy from lightning strikes, amino acids could spontaneously form in the oceans. This idea is now known as "primordial soup." In 1940, Wilhelm Reich invented the Orgone Accumulator to harness the primordial energy of life itself.
