What was Ptolemy's objection?
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.

Which of the following correctly lists the parts of the water cycle?
A) Evaporation, condensation, temperature, precipitation, collection
B) Condensation, build-up, runoff, precipitation, collection
C) Runoff, precipitation, evaporation, melting, condensation
D) Evaporation, condensation, precipitation, runoff, collection
Explain why
Answer:
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.

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.
