The fact that the majority of human newborns weigh around 7 pounds is reflective of ________________.directional selection stabilizing selection disruptive selection advantageos selection
The fact that the majority of human newborns weigh around 7 pounds is a reflective of stabilizing selection. Thus, the correct option is B.
What is Stabilizing selection?
Stabilizing selection is a kind of natural selection in which the population mean of a species stabilizes on a particular non-extreme trait value with majority of the population. This is the most common mechanism of action for the natural selection of a species because most of the traits do not appear to change drastically over a period of time.
Stabilizing selection is beneficial as it tends to narrow the variation in the phenotype of a population over time. This is the most common type of selection observed because it is associated with the adaptation of an organism to their environment. Thus, the weight of human newborns which is found to be 7 pounds for majority of individuals is an example of stabilizing selection.
Therefore, the correct option is B.

Which domain of life seems to be absent for deep-subsurface communities?
Answer:
Life consists of three domains bacteria, archaea, and eukaryotes. Bacteria and archaea are the two domains which can be found everywhere on the earth. Organisms from these two domains can be found in extreme conditions where eukaryotes cannot survive. These organisms are called extremophiles.
Deep subsurface has some extreme environment like high temperature and pressure where survival of eukaryotes is not possible but organisms from domain archaea and bacteria can flourish there.
These microorganisms have evolved some mechanism like special enzymes and protecting capsules which protect them in extreme climate of deep subsurface.
Therefore the domain of life seems to be absent for deep-subsurface communities is eukarya.

What types of minerals are among the most widely used in the world?
A. Metals
B. Alloys
C. Gemstones
D. Nonmetals
Final answer:
The most widely used minerals in the world are metals, like iron and aluminum, and nonmetals used in industry. Silicates are the most abundant mineral family, and metamorphic rocks form from sedimentary or igneous rocks. Gemstones and alloys are also valuable, but not as widely used as pure metals. So the correct answer is option A.
Explanation:
Among the most widely used minerals in the world are metals and to a lesser extent, nonmetals. Metals, such as iron, aluminum, and copper, are essential due to their electrical and thermal conductivity, malleability, ductility, and opacity. They are foundational in a vast number of industries, ranging from construction to electronics. Aluminum, for example, is used in various forms, from construction materials to packaging like aluminum foil. Meanwhile, nonmetallic minerals have a crucial industrial role as well, being used for chemicals, building materials, fertilizers, and abrasives.
The most abundant mineral family is the silicates, which form a significant component of the Earth's crust. Metamorphic rocks can form from both igneous and sedimentary rocks, under conditions of high pressure and temperature.
Minerals such as gemstones like diamonds and rubies, while being widely appreciated for their beauty and use in jewelry, are not among the most used materials industrially. Similarly, alloys, which are mixtures containing at least one metal, are very important in manufacturing but are a secondary category compared to pure metals.

1-A species of marine snails have either solid or striped shells. Scientists found that 57 percent of the snail population was striped, and 33 percent was solid. Sea birds are the main predator and when scientists studied their diet, they found that the birds ate more striped snails than solid snails. What could scientists conclude about the snails?
Birds preferred the solid snails. Rates of predation determine shell pattern. The shell pattern is due only to environmental variation. There may be other factors in the ecosystem that favor striped snails. Question 4(Multiple Choice Worth 3 points)
2- In 1989, the Exxon Valdez spilled nearly 42,000,000 liters of oil into Prince William Sound, Alaska. How would this spill be classified? Abiotic environmental Biotic environmental Genetic Pathogenic
Answer:
1. The correct answer would be "There may be other factors in the ecosystem that favor striped snails".
Solid snails are less hunted by sea birds as compared to the stripped snails. Therefore, we can conclude that the solid snail provides some kind of survival advantage to the population.
However, the percentage of solid snails as low as 33 percent. Thus, there must be some other environmental factors which favor the high percentage of striped snails.
2. The correct answer would be abiotic environmental.
In ecology, the abiotic component refers to the non-living component of the environment. For example, air, water, mountains, soil, minerals et cetera.
Similarly, oil being a chemical is a non-living thing.
Thus, it is an abiotic environmental factor.
Final answer:
Scientists might conclude that other factors in the ecosystem favor striped snails beyond merely predatory patterns, such as camouflage adaptation. The Exxon Valdez oil spill is classified as an abiotic environmental disaster.
Explanation:
Given the information that 57 percent of the snail population was striped and 33 percent was solid, and considering that sea birds ate more striped snails than solid, one could conclude there may be other factors in the ecosystem that favor striped snails. Since birds eat more striped snails despite their prevalence, it implies the birds do not prefer one type over the other based on appearance alone. Therefore, the pattern of predation does not seem to be the sole factor determining the shell pattern of these snails. Factors such as camouflage may play a role as indicated by research suggesting that snails with certain colorations may be better adapted to their native regions, possibly to avoid predation effectively.
Regarding the Exxon Valdez oil spill in 1989, since it was an oil spill, it would be classified as an abiotic environmental disaster. This term is used to describe a non-living chemical or physical factor in the environment that has a significant impact on living organisms and the ecosystem.

What is the main difference in purpose between the mitosis and meiosis
Answer:
Meiosis involves two divisions of the nucleus, while mitosis involves only one. Meiosis produces four sex cells that are haploid, meaning they have half the number of chromosomes. Mitosis, on the other hand, produces two cells that are identical to the original cell. These cells are diploid, meaning they have pairs of chromosomes.

The Earth comprises of a series of layers, that is, the crust, the mantle, the outer core, and the inner core.
The crust floats on a layer of semi-molten rocks known as the mantle. The mantle is the thickest layer of Earth, that is, of about 3000 kilometers and comprises of semi-molten rocks. In the mantle, the molten rock is known as magma.
Thus, mantle is the thickest layer of the Earth.
scientists have never seen the ancient horses shown in figure 16-4 what do you think was the main type of evidence scientists used to prepare these diagrams
It is likely that scientists used fossil evidence to prepare these diagrams. Even if a complete fossil of a particular species is never found, a critical mass of fossil evidence can reveal a lot of information. Even a single key leg bone can provide a good idea of the physiological form and size of that individual animal. Continual fossil discoveries and debate amongst paleontologists will begin to develop a consensus of what the species likely looked like.
