Answer:
What Are Red Blood Cells?
Red blood cells carry fresh oxygen throughout the body. This is important to your health. Red blood cells are round with a flattish, indented center, like doughnuts without a hole. Your healthcare provider can check on the size, shape, and health of your red blood cells using a blood test. Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.
Red blood cells are made in the bone marrow. They typically live for about 120 days, and then they die.
What are some design limitations of making a scale model of the Milky Way galaxy?
Answer:
(One light-year = 9.5 x 1012 km) Would it be difficult to make a scale model of the Milky Way Galaxy showing both the size of the Sun (diameter = 1.4 x 106 km), as well as its distance from the center of the galaxy (30,000 light-years)? size (TLS) and true smallest size (TSS) in cm. Then the units will cancel out.

Yeast cells obtain energy under anaerobic conditions through the
process of...
Answer:
If no oxygen is available, yeast will switch over to a process called anaerobic respiration - in this process, glucose (sugar) is fermented to produce energy, carbon dioxide, and ethanol. ... The thing about respiration is that the yeast cells only do it for the sake of producing energy
The conditions through which yeast cells obtain energy under a anaerobic conditions through the process called fermentation.
Yeast cells are unicellular fungal organisms.
They are known to be different from other fungi because they reproduce through the process of budding.
For these yeast cells to be able to function properly energy is needed for their metabolism and reproductive.
Fermentation is the anaerobic (absence of oxygen) break down of glucose molecules with formation of pyruvate.
The pyruvate generated is converted to Adenosine triphosphate (ATP) which is the form of energy used by these yeast cells.
Therefore, yeast cells obtain energy under anaerobic conditions through the process of fermentation.

When a mass of hydrogen has enough density, it begins to fuse the hydrogen atoms together. This fusion process creates large amounts of heat and light.
When a mass of hydrogen begins the fusion process, it is classified as a —
star
nebula
galaxy
planet
Answer:
star
Explanation:
a star forms with hydrogen
When a mass of hydrogen begins the fusion process, it is classified as a star. The correct option is A.
What is a star?From the moment the first gas cloud begins to compress to the time the star is formed and begins to shine like the Sun, the process of star creation takes roughly one million years.
When a quantity of hydrogen is dense enough, the hydrogen atoms start to fuse together. It also produces light and heat. A portion of the hydrogen's mass is transformed into energy during the process.
Deuterium and tritium combine to form an atom of helium in the simplest fusion reaction. Fast particle density, close particle closeness, and a high rate of speed are three requirements for nuclear fusion.
A buildup of gas and dust falls under the influence of gravity to generate stars.
Therefore, the correct option is A. star.

Which of the following is not a part of Darwin's theory of evolution?
a. Changes in organisms occur immediately.
b. Organisms change over time.
c. Species evolution occurs through natural selection.
d. Organisms developed from common ancestors.
Answer:
a
Explanation:
Evolution is supposed to take place over a long period of time and is made up of small changes
Changes in the evolution take time. The correct answer is option a.
What is the important key for the survival of any species ?It is that the species which are prone to the adaptation and are flexible enough to get to the new type of adaptation are called as the fittest species and they invade the land.
Organisms definitely do change with time where the organisms are thought to have a proper phylogeny behaviors where the different species are thought to have changed with the time where suppose one species that is the species which tend to change with the changing environment and tend to adapt.
Organisms definitely developed from common ancestors for example in the case of primates it is having the common phylogeny behavior as the species do share the common ancestry. Various primates are having the same behaviors.

Which of the following characteristics would be the most accurate in hierarchically classifying a newly discovered organism? habitat or
behavior or
genetic material
or reproductive strategies
Answer:
Genetic material
Explanation:
Living organisms have been hierarchically classified into groups. For a newly discovered organism, the most accurate characteristics that could be used to classify such organisms will be the GENETIC MATERIAL. The genetic material shows the evolutionary relationship between the new organism to ones that have existed and been classified.
Organisms with similar genetic characteristics are similar to one another, hence, that can be used as an accurate means of classification. The DNA of an organism can serve as an evidence to place an organism in a particular hierarchical group called Taxonomy.

describe the motion of the particles
of a liquid when heat added.
Answer:
Hope this helps!
Explanation:
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.
Answer:
The liquid turns into a gas and the particles move around freely and fast.

An element has 2 valence electrons and 3 energy levels. It is located in
group
Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?
We have that for the Question " An element has 2 valence electrons and 3 energy levels. It is located in group" it can be said that its the
Group three(3)
From the question we are told
An element has 2 valence electrons and 3 energy levels. It is located in
group
Generally
We have that the energy level of three is synonymous to elements of group three
Therefore
Sodium has has a 3 valences which continues to add electrons to its outermost shell up untill the element Ar
Hence
its the Group three(3)

Sample Response: Federalists believed in a strong central government. They argued in favor of separation of powers: the division of the government into three separate branches whose powers balance each other. They felt this would be necessary and helpful. On the other hand, Anti-Federalists were fearful that the separation of powers would not equally balance power. They did not believe that this separation could occur in a fair way.
Answer:
This represents a conflict Federalist vs antiferalists
Explanation:
Federalists and anti-federalists were two groups formed during the conventions to decide how the country would be governed and to decide the nation's legislative body through the federal constitution.
The federalists were represented by John Adams, Alexander Hamilton and George Washington who preached the need to establish a central government divided into three spheres that complemented and acted on different elements. The anti-federalists, on the other hand, led by Patrick Henry, believed that federalism gave the president too much power, allowing him to act like a king and that he could abuse power, in addition to exploiting the nation.
The ideological differences of these two groups led to many discussions and conflicts, but it ended with the adoption of federalism in the country.
