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.
Some organisms, such as fish and mosquitoes, produce very large numbers of offspring. Why is producing a large number of offspring important for natural selection?
Answer:
Because a lot of the offspring die
Fish lay lots and lots of eggs but very few survive
It is important, so they can grow up and continue the lifeline of that animal, or that generation of animal

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.

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.

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.

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
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.

5. How is this different from Darwin's idea of fitness?
Answer:
Darwinian fitness differs from the “physical fitness”, which is more associated with health, muscle tissues, oxygen, and physical effort. Darwinian fitness is more concerned about reproductive success. Darwinian fitness describes how successful an organism has been at passing on its genes.

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.

Which two parts of the water cycle involve water in its gas form?
A) Condensation and collection
B) Evaporation and condensation
C) Precipitation and condensation
D) Runoff and evaporation
Explain why.
Evaporation and condensation involve water in its gas form. Hence, option B is correct.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle. It is a very important cycle for the survival of living organisms.
The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When the water in rivers, lakes, or the ocean is heated by the sun and turned into vapor or steam, this process is known as evaporation. In condensation, water vapors are converted into water.
The parts of the water cycle that involve water in its gas form are evaporation and condensation. Hence, option B is correct.
