Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.

Which has a lower albedo, a black sheet of paper or a white sheet of paper?
Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
Answer:
osmosis
Explanation:
plants use osmosis whic is moving water though a semipermial membrane to draw up water. It moves from places of high conetartions of water (dirt) has to is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.
Plants use osmosis which is moving water though a semipermial membrane to draw up water.
What do you mean by osmosis?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.
Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.
The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.

1. Which of the following is NOT a key factor important to the development of human society?
A. Access to clean water
B. Access to fertile soil
C. Access to cities
D. Access to natural resources
Access to cities is not a key factor important to the development of human society, but clean water, fertile soil, and Access to natural resources all are needed, hence option C is correct.
What are factors important to the development of human society?The preagricultural (hunting and gathering) stage, the agricultural stage, and the industrial stage are thus the at least three primary stages of societal evolution or civilizations.
Clean water is essential to our way of life because it creates a habitat for species and places to fish, paddle, surf, and swim. Our economy is reliant on clean water to operate and thrive. This includes industries like manufacturing, agriculture, tourism, recreation, and energy generation.
They support tax revenue, income, and the fight against poverty. Natural resource-related industries generate employment and frequently form the backbone of poorer towns' economies.
Therefore, natural resources are fundamentally important, so they must be managed responsibly.

Which of the following is NOT in part of the natural selection process?
A. a species produces more offspring than can survive
B. an organism adapts to their environment causing variation
C. individuals competing with each other
D. fossils being formed
Answer:
the selection that is not a natural selection process is D: fossils being formed
Answer:
D. Fossils being formed
Explanation:
In the natural selection process, the point is that the animal which is best adapted to the environment survives, so their offspring can survive and produce more offspring that adapts. This is because organisms need to adapt to their environment to survive. Without natural selection, most animals would be too weak to live in their own habitat.
So when we see the answer choices, we have to ask if the species could continue to live and adapt.
A- the species produces more offspring that can survive. Yes, the species can continue to live and adapt.
B- an organism adapts to their environment. Yes, the species can continue to live and adapt.
C- individuals competing with each other. Yes, the better species will win, and continue to live and adapt
D- fossils being formed. No, this has nothing to do with the process of living and adapting. It is in fact the opposite, since it relates to the species dying.
So the answer is D

If a couple has four daughters the % chance of their next child being a daughter is
Answer:
50% chance
Explanation:
Humans have two sex chromosomes, the X chromosome and the Y chromosome. Males inherit both X and a Y chromosome, while females inherit two X chromosomes. Thus, the sex of the child is determined by the sex chromosome carried by the male gamete (i.e., X or Y chromosome) which fuses with the egg cell (always containing an X chromosome). In consequence, the chance of having a sperm containing an X chromosome (i.e., the chance of having a girl) is an independent event of previous fertilization events (which led to the formation of 4 different female zygotes), thereby the probability will be 50%.
Helppppp please What characteristic of water
means that clear water is not
necessarily clean water?
A. the density of the water
B. high specific heat capacity
C. the temperature of the water
D. ability to act as a universal solvent
Answer:
B
Explanation:
Ability of water to act as a universal solvent means that clear water is not necessarily clean water. Therefore, option (D) is correct.
What is clean water?Clean, safe water is defined by the USGS as "water that won't hurt you if you come in touch with it." Although drinking water is often mentioned when discussing clean water, clean water is also crucial for all residential uses.
It is impossible to smell, taste, or even see the microscopic contaminants that pollute water, such as bacteria, viruses, and parasites. Therefore, just because your water is clear doesn't imply it's okay to drink.
Therefore, due to the fact that water is a universal solvent, meaning that it is capable of dissolving a wide range of substances with relative ease clear water is not considered clean.

12 ounce = 12 × 12 × 5
= 144 × 5
= 720 calories
Thus, it is found out that he has added 710 calories approximately to his diet additional.

What is the structure of DNA?
Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
Deoxyribonucleic acid (DNA) is made up of the four nucleotides A, C, G, and T. These nucleotides are linked together by a backbone made up of alternating phosphate and deoxyribose sugar residues. The complementary pairs of these nitrogen-containing bases are governed by their capacity to generate hydrogen bonds.
DNA is located inside the nucleus, a specific region of the cell, in eukaryotic species.
Therefore, chromosomes are the name for this DNA that has been packed.

1. In the process of (selective breeding / natural selection/hybridization/
DNA replication), plants or animals with desired traits are mated. By repeating
the process over many generations, useful plant strains or animal breeds are
developed. The process is an example of (bioremediation / natural selection /
biotechnology / feedback inhibition).
Answer:
selective breeding; biotechnology
Explanation:
Selective breeding is a type of artificial selection that consists of crossing plants/animals with desirable and heritable phenotypic traits in order to increase the frequency of such traits in progeny. Selective breeding can be considered as one of the first biotechnological techniques applied by humans. In the past, the selective breeding technique has allowed obtaining domesticated animals (e.g., dogs from wild wolves) and domesticated crops from their wild ancestors (e.g., maize from its wild ancestor teosinte).
