Does natural selection affect humans? How and why
Answers
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.

Answers
Answer: A. Iron and E. Nickel
Explanation:
Earth's core is the center part of the planet and it is very hot in nature. It is the center of geothermal activities. It is like a furnace. It is associated with intense heat and pressure in the center. It is composed of iron and nickel. The crust and mantle are rich in many minerals. The core is made up of outer core and inner core. The outer core is in borders with the mantle. The temperature of the inner core is higher than the melting point of iron.

D) Evaporation, condensation, precipitation, runoff, collection
Please give me brainlyest
Explanation: The water cycle shows the continuous movement of water within the Earth and atmosphere. System that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Then I does runoff and creates a new water source or goes back to a water source.

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.
Answers
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.

1. An atom of which element has 37 protons, 48 neutrons and 1 valence electron? Answer:
Answers
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.

Zebrafish (Danio rerio) is an important model organism in the field of genetics. One of the first mutant genes to be studied in this species was golden. The mutant allele was discovered in a pigmentation mutant purchased from a pet store, which changed the color of the fish from the wild-type silver-white coloration to a pale golden color. Calculate the percent likelihood of golden offspring from a cross between a heterozygous wild-type male fish to a golden female fish a 0% b 50% c 25% d 100%
Answers
Answer:
b
Explanation:
Let the wild type trait, the silver-white, be represented by A allele and the mutant trait, the golden color, be represented by a allele.
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
Hence, the percent likelihood of golden offspring is 2/4 or 50%.
The correct option is b.

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.
Answers
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.
