Answer:
they grow, reproduce and die.
Explanation:
Microorganisms are a way of life that cannot be visualized without the aid of a microscope. These tiny beings can be found in the air, on the ground, and even in man. These tiny beings are not all the same, they can be very different in size and way of life. However, they all have in common a very simple structure and the impossibility of being seen without the use of a microscope. In addition, microorganisms can represent some characteristics of life, since as well as living beings in gereal they grow, reproduce and die.

It’s easier to determine the elecron configurations for the p-block elements in periods 1,2,3 than to determine the electrons configurations for the rest of the p-block elements in the periodic table beacause
Answer:It’s easier to determine the elecron configurations for the p-block elements in periods 1,2,3 than to determine the electrons configurations for the rest of the p-block elements in the periodic table beacause from period 4, specifically from the element 31 (Ga), the atoms start to fill the d orbitals, and the energy levels of the 3d orbitals ara quite similar to the energy levels of 4p orbitals. So, for the elements Cr and Cu the right configurations do not match the configurations predicted using Aufbau method and Hund rules. Those are not the only exceptions but the two first. All is due to the proximity of the energy of the d and p orbitals and the fact that the rearrangement of the electrons result in a lower energy

WHAT ARE NEWTON'S 3 LAW'S
Final answer:
Newton's three laws of motion are fundamental principles in classical mechanics, explaining how objects behave under various forces. The first law, or law of inertia, says objects maintain their state of motion unless acted upon by an external force. The second law relates force, mass, and acceleration, while the third law states that every action has an equal and opposite reaction.
Explanation:
Isaac Newton's three fundamental laws of motion form the basis for classical mechanics, describing the relationship between a body and the forces acting upon it. The laws are integral to our understanding of interactions and forces in physics.
Newton's first law, also known as the law of inertia, asserts that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force. Newton's second law advances this concept by stating that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. Lastly, Newton's third law establishes that for every action, there is an equal and opposite reaction, meaning that forces between two interacting objects are equal in magnitude and opposite in direction.
Which of the following techniques can be used to separate a homogeneous mixture into its component parts?

The right is Separation by density .
Take the blood which is a good example of a heterogeneous mixture.
Blood is a vital liquid in our body, which transports oxygen from the air to our lungs so we can breathe. It is also used to eject wastes, such as carbon dioxide, to bring cells and molecules of the immune system to the tissues, and to spread hormones throughout the body. It corresponds to plasma, red blood cells, white blood cells, platelets and hemoglobins combined.
In medical tests centrifugal force is used to separate the different components of the blood.
In general, the centrifugation will allow to separate and analyze the different components of the blood, to know if the rate of white blood cells in the blood of a patient, for example, is normal, and therefore to know if his system Immune is integrity.
Under the action of centrifugal force, the solid components in the blood are drawn to the bottom of the tube in which the blood is contained. The centrifugal force then acts as an accelerated settling. It separates plasma from red blood cells and white blood cells.
Answer:
The answer is seperation by density! Hope this helped

Why is the air warmer than the water in a pool on a hot sunny morning? due to surface tension because of water’s specific heat because of capillary action due to water’s solvent properties
The air is warmer than the pool water because water has a high specific heat, requiring more energy to increase its temperature than air does. Option B is correct.
Specific heat is the amount of energy required to raise the temperature of a substance. Water has a high specific heat, which means it takes more energy to increase its temperature compared to air. This property allows water to absorb a lot of heat without a significant rise in temperature, hence it often feels cooler than the air on a sunny day.
Furthermore, it's also worth noting that this high specific heat of water plays a crucial role in Earth's climate and helps to moderate temperatures.
Hence, B. is the correct option.
The complete question is:
Why is the air warmer than the water in a pool on a hot sunny morning?
A) due to surface tension
B) because of water’s specific heat
C) because of capillary action
D) due to water’s solvent properties

How many grams of O are in 585 g of Li2O
The amount of oxygen in 585 g of Li2O is calculated using the molar mass of Li2O and the proportion of oxygen's molar mass to Li2O's molar mass, then multiplied by the total mass of Li2O.
Explanation:To determine how many grams of oxygen are in 585 grams of Li2O, we use the molar mass of Li2O and the molar mass of oxygen. The molar mass of Li2O (lithium oxide) is the sum of the mass of two lithium atoms and one oxygen atom. One mole of Li2O weighs approximately 29.88 g/mol (2 x 6.94 + 16.00), and one mole of oxygen weighs 16.00 g/mol.
To find the mass of oxygen in Li2O:
First, find the moles of Li2O in 585 g: Moles of Li2O = 585 g / 29.88 g/molNext, find the grams of oxygen in that amount of Li2O moles using the molar mass of oxygen: 16.00 g/mol.Multiply the moles of Li2O by the molar mass of oxygen.Therefore, to calculate the exact grams of oxygen in 585 g of Li2O, you use the proportion of oxygen's molar mass to Li2O's molar mass, which is 16.00/29.88. Multiply this by the given mass of Li2O to find the mass of just the oxygen part:

To determine the grams of oxygen in 585 g of Li₂O, first calculate the molar mass of Li₂O, find the number of moles in 585 g, and then convert the moles of oxygen to grams. The final result is 335.84 grams of oxygen.
To find the number of grams of oxygen in 585 g of Li₂O, we need to follow these steps:
Determine the molar mass of Li₂O by summing the atomic masses of its elements: Lithium (Li) has an atomic mass of 6.94 g/mol and Oxygen (O) has an atomic mass of 16.00 g/mol. Thus, the molar mass of Li₂O is: (2 * 6.94 g/mol) + 16.00 g/mol = 27.88 g/mol.Calculate the number of moles of Li₂O in 585 g: Number of moles = Mass / Molar Mass = 585 g / 27.88 g/mol = 20.99 moles of Li₂O.Since there is 1 mole of oxygen in each mole of Li₂O, there are 20.99 moles of O in 20.99 moles of Li₂O.Convert moles of O to grams by multiplying the number of moles by the atomic mass of O: Mass of O = Number of moles * Atomic Mass = 20.99 moles * 16.00 g/mol = 335.84 g.Therefore, there are 335.84 grams of oxygen in 585 grams of Li₂O.
Which of the following is necessary for plants to exhibit phototropism?
A. Gravity
B. Touch
C. Auxin
D. Dormancy
Answer: C. Auxin
Explanation:
Phototropism can be define as the growth of the plant in response to the stimulus of light. The plant parts grow in direction of the sunlight this phenomena is called as positive phototropism. For example, stem. The plant parts when grow against the direction of sunlight this phenomena is called as negative phototropism. For example, root.
The auxin is a plant hormone which is responsible for phototropism. It moves to the darker side of the plant and helps the growth of the plant on that side as compared to the lighter side of the plant. This results in curving of the plant stem tip towards the light hence, results in positive phototropism.
Which statement differentiates between prokaryotic cells and eukaryotic cells?
Eukaryotic cells have DNA; prokaryotic cells do not.
Prokaryotic cells have DNA; eukaryotic cells do not.
Eukaryotic cells have nuclei; prokaryotic cells do not.
Prokaryotic cells have nuclei; eukaryotic cells do not.
Answer:
Eukaryotic cells have nuclei; prokaryotic cells do not.
Explanation:
Eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus. All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely.
Answer: Eukaryotic cells have nuclei; prokaryotic cells do not.
Explanation: Eukaryotic cells have chromosomes that are enclosed in nucleus and are separated from the cytoplasm by the Nuclear membrane.
Whereas, on the other hand, Prokaryotic cells only have small range of organelles, usually only a plasma memrane and ribosomes.

Frank and Lisa are analyzing the chart, which shows the speed at which light travels through different media.
Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency.
Which best describes the accuracy of these statements?
a.Frank is correct because light travels through diamond at the slowest speed, and speed and frequency have an inverse relationship.
b.Lisa is correct because light travels through air at the fastest speed, and speed and frequency have a direct relationship.
c.Neither person is correct because light does not change frequency when it travels through different media.
d. Both people are correct because light has both an inverse and a direct relationship with frequency, depending on the media.
Answer: The correct answer is "Neither person is correct because light does not change frequency when it travels through different media".
Explanation:
The speed of the wave depends on the medium through which it is travelling. The speed of the light is more in the rarer medium than the denser medium.
Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency. Both are wrong as the frequency remains constant when the light is travelling from one medium to another. The speed of light is lowest in diamond.
Therefore, the correct option is (c).
