Answer:
interphase
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
All of the following are reasons that Mendel chose the pea plant as a model system for his studies EXCEPT ________.
The group of choices is:
peas have a relatively short generation time
peas produce large numbers of seeds
he could control which parents were involved in mating
peas only reproduce by cross-fertilization
peas have many polymorphic traits
Answer:
The correct answer is - peas only reproduce by cross-fertilization
Explanation:
Pea plants not just produced by cross-pollination but self-pollination is also one of the reproduction methods present in it. Pea plants have many type of characteritics or traits that can be controlled by the researcher in parent plants during the mating process.
The generation is relatively short which helps in the study the pattern of inheritance of the traits up to several generations.
Thus, the correct answer is - peas only reproduce by cross-fertilization

Which phrase justifies why the theory of evolution is a theory and not a law?
A)Describes the relationship between an organism and its environment
B)Makes accurate predictions based on only a small amount of empirical evidence
C)Explains diversity based on the principle of natural selection
D)Cannot be modified with the discovery of new evidence
Answer:
I think it is D
Explanation:
Because if new evidence cannot be added to it then it is only based on a small amount of evidence. And if new evidence proves it invalid or wrong then it is just a theory then.
Answer:
A. Describes the relationship between an organism and its environment
Explanation:
Carnivorous plants and legumes (e.g., peas, soybeans) both absorb key nutrients directly from other organisms. How is nutrient acquisition in pitcher plants similar to that in legumes
Answer:
They acquire nitrogen from the insects they eat.
Explanation:
Pitcher plants is a canivorous plants.
Since both legumes and pitcher plants absorb nitrogen from other organisms, pitcher plants have specialised pitfall trap called pitcher found at their leaves which help help to trap, and digest insects that are prey. The obtained about 80% nitrogen from the insects they eat which is captured by their leaves.. They release digestive enzymes which acts on their insects and then decompose by bacteria to release nitrogen . This nitrogen is turn to liquid which is absorb as liquid and use for growth.

explain the process of how sedimentary rocks form.
Answer:
Sedimentary rocks are formed from the weathering of other rocks, dead organic remains or chemical precipitation.Sedimentary rocks form when mud and sand are deposited in layers on the Earth's surface. The layers are deposited in many environments including oceans, rivers and deserts. These layers of sand and mud are later buried. The weight of overlying layers compresses the mud and sand to form solid rock. Steps:
Sedimentary rocks are the product of :
1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.
How does surface tension work with water molecules?
Answer:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. At the surface, though, the outmost layer of molecules, has fewer molecules to cling to, therefore compensates by establishing stronger bonds with its neighbors, this leading to the formation of the surface tension.
Surface Tension of Water . The surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph. The surface tension arises from the polar nature of the water molecule.

When should we clessify something as not living?
Answer:
A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

what experminental erros do you expect to encounter when developing an experiment involving hot water
Answer:
The correct answer would be - unstable water temperature as heat lost with time.
Explanation:
Heat is a physical property that continuously decreases with time so in any experiment, if hot water is involved it might lose its heat with time so there will be less temperature than the initial of the experiment or when it has been heated.
Heat can be lost to its surrounding or lost by in close contact with other components of the experiment like container.

Explain the difference between macrostates (external arrangements of particles) and microstates (internal arrangements of particles).
Macrostates and microstates may be defined on the basis of their properties and characteristics. Both are part of any system.
What do you mean by Macrostates?Macrostate may be defined as defined by the macroscopic properties of the system, such as temperature, pressure, volume, etc.
Microstate may be defined as the arrangement of each molecule in the system at a particular instant. It governs the internal arrangement of particles in a system. While macrostate is the possible outcome that governs the external arrangement of particles in the system in a definite way.
Therefore, Macrostates and microstates may be defined on the basis of their properties and characteristics.

Explain how you could use a balloon to show a friend why the universe looks the way it does.
Answer: When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang.
Explanation: The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.
However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity.

When light is reflected, what determines the angle of reflection?
Answer:
The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
Explanation:
The law of reflection states that θi = θ r, or in other words, the angle of incidence equals the angle of reflection. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index.
What determines the angle of reflection is the angle of incidence
When light is reflected on a plane surface the angle of reflection is equal to the angle of incidence i.e. θr = θi .
Angle of reflection ; This is the angle between the reflected ray and the normal ray on a reflecting surface while.
Angle of incidence ; This is the angle between the direction of an oncoming ray ( incident ray ) and the line perpendicular to the reflecting surface.
Hence what determines the angle of reflection is the angle of Incidence

Which best describes the flow of oxygenated blood through the heart?
Question 1 options:
Left pulmonary veins, right atrium, right AV valve, right ventricle, aortic semilunar valve, aorta
Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, aorta
Superior vena cava, left atrium, left AV valve, left ventricle, pulmonary semilunar valve, left pulmonary artery
Superior vena cava, right atrium, right AV valve, right ventricle, pulmonary semilunar valve, left pulmonary artery
Answer:
Explanation:
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
The correct option that describes the flow of oxygenated blood through the heart is B, Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, and aorta.
The left atrium is where oxygenated blood enters the heart after traveling from the lungs to the heart via the pulmonary veins. The left AV (atrioventricular) valve, also referred to as the mitral valve, allows blood to pass from the left atrium into the left ventricle.
The aortic semilunar valve, the body's primary artery that carries oxygenated blood to all the organs and tissues, is opened as the left ventricle contracts, pumping blood out into the body.
