Answer: Rubidium

Explanation:

The atom with 37 protons, 48 neutrons, and 1 valence electron is Rubidium (Rb).

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.

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.

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

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.

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.

Answer:

the sun hot stuff

Answer: Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level.

If you want to know the main source of energy... the answer is the sun.

Evaporation and condensation involve water in its gas form. Hence, option B is correct.

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.

Answer:

plants, animals, microorganism and bacteria

Explanation:

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.

The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.

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.

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.

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.
