Which of the following is an example of reproductive isolation? two populations of finches that cannot produce viable offspring two populations of finches that have different feather colors two populations of salamanders that live in different lakes two populations of salamanders that have different tail lengths
The correct answer is A. Two populations of finches that cannot produce viable offspring
Explanation:
Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.

Answer:
A.) for souvenirs
Explanation:
Tourists are interested in mining corals mainly to get souvenirs, since corals are known to be pretty and would be a "good" souvenir because of that.
Tourists would not be interested in mining corals to build roads, get protection, or get bone grafts because tourists are just interested in visiting a place and getting souvenirs from it.
Coral mining is the removal of coral reefs through various methods. The tourists mines coral to keep or gift them as souvenirs. Thus, option A is correct.
What are corals?Corals are the hard aquatic invertebrates that belong to the phylum Cnidaria and are found in the form of colonies and as individual polyps. They together make a coral reef that is an important part of the ecosystem.
Though the polyps are softer they secrets a harder covering of shells made of calcium carbonate that gives an appearance of a hard skeleton or rock. The mining of corals has been seen as having a negative impact on the ecosystem as protects from erosion and is a source of medicines and home to various marine organisms.
The corals have been mined by the tourist to keep them as souvenirs. It is seen that they are pretty and is good to keep. They act as tokens of remembrance for the tourist as they have visited the place and are beautiful.
Therefore, option A. the tourists keep coral as souvenirs.

Describe how Stella’s view of these cells and their parts changed as she transitioned through the three levels of magnification. Be sure to identify at least one cell structure or part of the paramecium in your description.
Answer:
The paramecium body.
Explanation:
1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.
At 40x magnification Stella will see organism 5mm.
At 100x magnification Stella will be able to see organism 2mm.
At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.
2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.
Pellicle capacities like skin and shields them from the components. For movement they have cilia.
Answer:
At 40x, Stella could see the cells, but they looked really small. At 100x, Stella was able to see the cells to the point where she could see most of them up close. At 400x, Stella could see the cells one by one close enough. Some of the cells are shoe-shaped, which is one of the characteristics of paramecium. The brown at 400x next to the orange is the one that mostly looks like a shoe.

Anaerobic respiration in yeast.
Anaerobic respiration is economically important - many of our foods are produced by microorganisms respiring anaerobically. Yeast is used to making alcoholic drinks. When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up.
How do humans benefit from the products of anaerobic respiration?Another advantage of anaerobic respiration is its speed. It produces ATP very quickly. For example, it lets your muscles get the energy they need for short bursts of intense activity (see figure below). Aerobic respiration, on the other hand, produces ATP more slowly.

On each step in Electron Transport Sustem chain, a small charge is given off that will be used to synthesize ATP in the process of phosphorylation. When the electrons leave the chain, in pris, they combine with oxygen (final acceptor) to form water. During this process water is and why:
A) oxidized because electrons are lost which produces oxidized water
B) oxidized because electrons are gained which produces oxidized water
C) reduced because electrons are gained which produces reduced water
D) reduced, because electrons are lost which produces reduced water
Answer:
C) reduced because electrons are gained which produces reduced water
Explanation:
The electron transport chain (ETC) involves a series of chemical reaction based on the reduction and oxidation of molecules. According to the question, the electrons that leave the chain combine with a final electron acceptor called Oxygen. This reaction is a reduction reaction because oxygen gains electrons.
The gaining of electrons by Oxygen reduces it to water (H2O). Hence, water is said to be reduced because electrons are gained by oxygen to produce a reduced form, called water.

Answer:
it acts as products/reactants it acts to stablize the temperature
Explanation:
Dry heat sterilization is very useful to be used in materials that cannot come into contact with forms of heat sterilization such as steam. It is also widely used for objects that cannot come into contact with very high temperatures.
This type of sterilization is done by buckling, incineration, intra-red rays or hot air oven. In any case, it is important that the water is completely removed, both from the object and from the sterilization vehicle. This is because water is easily used by possible microorganisms to stabilize the temperature in their bodies, which can cause sterilization failures.
