What property allows carbon to form a wide variety of molecules?
a. It is the fourth most abundant element in the universe.
O b. It has an average mass of 12 AMU.
O c. It's electron configuration.
.
O d. It's number of protons.
Answer:
O c. It's electron configuration.
Explanation:
Electronic configuration is the property that allows carbon to form a wide variety of molecules. It is fourth most abundant element in the universe after hydrogen, helium and oxygen. It has four electrons in its outermost shell due to which carbon forms four covalent bonds with other elements such as hydrogen, oxygen, and nitrogen. Carbon also has the ability to making rings.
In osmosis molecules move through a semi-permeable membrane from a high concentration to a low concentration. True or False
Answer:
False
Explanation:
Osmosis is the movement of water molecules through a selectively permeable membrane from high to low concentrations.
Diffusion is the process in which molecules move from an area of high concentration to low concentration.
The statement doesn't say that the molecules are water, so we put false. If it is wrong then tell the teacher that she has to include water molecules in there to be more detailed.

Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.
The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.
What is competitive exclusion?It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.
Characteristics of the competitive exclusionThe competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

Explain briefly HOW we have different cell types (blood, skin, muscles, nerves, etc.) *
Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense

Quail use feathers for thermoregulation, flight and camouflage. What type of adaptation are feathers?
A. Structural
B. Behavioral
C. Physiology
D. Feathers are not an adaptation
Answer:
structural
Explanation:
In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.
Place the steps below in order from the first to happen to the last that will happen in hemostasis. Chemicals are released from the injury site and from underlying callogen. A blood vessel is severed. Blood and blood components leak out the breaks. The platelets become activated making them spiked and sticky. Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot. Fibrinogen is converted to fibrin. The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Answer:
A blood vessel is severed.
Blood and blood components leak out the breaks.
Chemicals are released from the injury site and from underlying callogen.
The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Fibrinogen is converted to fibrin.
The platelets become activated making them spiked and sticky.
Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot.
Explanation:
Hemostasis is the process by which the body prevents and stop blood loss through bleeding.
Hemostasis occurs in three steps:
1. Vasoconstriction: Once a blood vessel is severed or cut, the smooth muscles of the blood vessels start to constrict or get narrower around the severed vessel in order to reduce blood flow through it. This vasoconstriction occurs in response to chemicals released from the cut vessel and the underlying collagen.
2. Platelet-plug formation: the platelets become activated by a glycoprotein called Von Willebrand factor (vWF), which is found in plasma and begin to clump together sticking together. This is known as primary hemostasis.
3. Clot formation: in response to platelet-plug formation, several clotting factors are activated which eventually convert fibrinogen to fibrin. Fibrin is mesh-like and holds the platelets as well as red and white blood cells in place, thereby forming blood-clots over the wound.

Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.

1. An atom of which element has 37 protons, 48 neutrons and 1 valence electron? Answer:
Answer: Rubidium
Explanation:
The atom with 37 protons, 48 neutrons, and 1 valence electron is Rubidium (Rb).
Which element has 37 protons, 48 neutrons, and 1 valence electron?Rubidium (Rb) is the element that has 37 protons, 48 neutrons, and 1 valence electron. Protons and neutrons are located in the nucleus of an atom, while valence electrons are found in the outermost energy level or shell.
In the case of Rubidium, it has 37 protons which defines its atomic number and element identity. Also, it has 48 neutrons which contribute to its atomic mass. The valence electron of Rubidium is in the outermost energy level making it readily available for chemical reactions and interactions with other atoms.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
