A student redid the experiment of mixing room-temperature water and warm
water. This time, she doubled the amount of warm water. How will the final
temperature be different?
A. It will be higher, because the amount of water in the mixture is
greater
B. It will be the same, because all parts of the mixture will end up at
the same temperature.
C. It will be lower, because the room-temperature water will absorb
more thermal energy from the warm water.
D. It will be higher, because the warm water will transfer more
thermal energy to the room-temperature water.

Answers

Answer 1
The answer is D because more volume of warm water will go into the mixture
Answer 2

The final temperature will be different by having a high temperature because the warm water will transfer more thermal energy to the room-temperature water. Thus, the correct option is D.

What is Temperature?

The Temperature may be defined as the degree of hotness or coldness measured on a definite scale at a particular location.

If we mix room-temperature water with warm water, the temperature of mixed water is found to be high as compared to the previous room water temperature. This is because warm water is capable of transferring its thermal energy to room-temperature water.

Therefore, the correct option for this question is D.

is water vapor slowing down due to loss of heat, causing the water molecules to stick together and reform into liquid water

Answers

When heat is applied to water, the transfer of energy causes the water molecules vibrate at a quicker pace. As the heat increases, the molecules get further apart, causing the water to change form from a liquid to a gas (aka vapor). As the molecules cool, they lose the energy from heat that was applied, causing the molecules to vibrate at a slower pace. As the energy is lost, the water molecules to come closer together, resulting in water returning to a liquid state.

what best describes a tetrad

Answers

Answer :

4 chromatids.

Explanation: the world needs answers , I can provide

Tetrad is best described by two sister chromatids, coming together to form a four-part structure.

A tetrad, also known as a bivalent, is a structure that forms during meiosis I in sexually reproducing organisms.

During prophase I of meiosis I, homologous chromosomes pair up and become physically connected along their lengths.

This connection between homologous chromosomes is called synapsis.

As a result of synapsis, a tetrad is formed, which consists of two pairs of sister chromatids, one pair from each homologous chromosome.

The tetrads play a crucial role in the process of genetic recombination or crossing over. During prophase I, while the tetrads are formed, the genetic exchange can occur between the non-sister chromatids of the homologous chromosomes.

Thus, a tetrad is a four-part structure formed by two pairs of sister chromatids that come together during meiosis I.

"Please compare and contrast the difference between photosynthesis and cellular respiration. Please include glucose, water, oxygen, carbon dioxide and the sun"

Answers

Answer:

The circulatory system of our body complies with the gas exchange in the pulmonary alveoli, there the oxygen enters and binds to a protein which oxidizes it, this protein is allosteric, and it is called hemoglobin, this hemoglobin travels the human body capturing every need punctual of each organ, some organs will demand more or less oxygen according to the metabolic state of the human system.

Once oxygen is in front of an organ with few partial pressures of oxygen, it is released from the hemoglobin and this protein changes its conformation and then re-oxidizes when passing through the pulmonary alveoli.

It is important to clarify that hemoglobin is found in red blood cells, and these in the blood where they are pumped and distributed by the cardiovascular system.

Sense of taste, smell, touch, hearing and sight.

In the spinal cord, it is related more than anything those touch receptors in charge of executing reflexes against injuries or harmful conditions, such as touch receptors that are in charge of measuring temperature and measuring the limb's withdrawal response to excessive heat or burn .

As for the central nervous system and the cortex, they are responsible for managing the signals sent by sensory neurons, associating them with feelings, memories and experiences, such as taste and smell.

Photosynthesis is a process where energy currency for plants is obtained as a product, it requires ultraviolet light and carbon dioxide as products, where plant chlorophyll intervenes and oxygen is released to generate food autonomy for plants.

On the other hand, the respiratory chain is a process where proteins are oxidized sequentially to allow the gas exchange of those living organisms.

Explanation:

Explanations one and three are related because they both explain breathing methods in plants and animals such as humans, while in question two the human nervous system is related to the perception of the environment through the senses.

Answer:

An organism that eats another organism is called a  consumer.

Explanation:

In food webs, consumers are characterized by not being able to produce their own nutrients, having to acquire them from the consumption of other living beings.

Consumers are found from the second level of the food web and can be primary consumers, or herbivores, and secondary, tertiary or even quaternary consumers, who are carnivores.

The other options are not correct, due to:

    a. Vertebrate : which has an internal skeleton, of a bony or cartilaginous nature.

Which statement provides the strongest evidence that these changes to global climate are NOT the result of natural causes, such as variations in Earth's orbit? 1 point Until recently, Earth's climate had remained relatively constant. Variations in Earth's orbit cannot be measured precisely. Variations in Earth's orbit would affect climate only minimally. Earth's climate depends mostly on the output of the sun. Variations in Earth's orbit occur gradually over 100,000 years.

If 5 ml of amylase, an enzyme which digest carbohydrates, is added to a vial with 10 ml of water and 10 ml of sucrose. At the end of the reactions, how much amylase do you expect to find in the vial?

Answers

Answer:

5ml

Explanation:

Enzymes are protein molecules that act as biological catalyst in living systems, as they help speeden up the rate of biochemical reactions. However, one unique characteristics possessed by enzymes unlike substrates is that they do not get used in the reaction. Instead, they are released from the substrate-enzyme binding after the reaction and can be recycled.

Hence, in a case whereby 5ml of amylase, an enzyme that breaks down carbohydrates, is added to a vial containing 10 ml of water and 10 ml of sucrose. The amount of amylase expected to be in the vial at the end of the reaction is 5ml because it will not get used up during the reaction. Hence, the volume of enzyme remains constant after reaction.

ollars. How many more meters of fabric

Answers

Answer:

163 fabric needed to make 250 collars.

Explanation:

Given that,

Length = 1.5 m

Width =137 cm

Number of order = 250

Use fabric = 65%

We  need to calculate the actual length need to make a collar

Using given data

[tex]Actual\ length =Length\times use\ fabric[/tex]

Put the value into the formula

[tex]Actual\ length =1.5\times\dfrac{65}{100}[/tex]

[tex]Actual\ length=0.975\ m[/tex]

We need to calculate the total length of fabric

Using formula for total length

[tex]total\ length=Actual\ length\times Number\ of\ collars[/tex]

Put the value into the formula

[tex]total\ length=0.975\times250[/tex]

[tex]total\ length=243.75\ m[/tex]

We need to calculate the number of fabric

Using formula for number of fabric

[tex]Number\ of\ fabric=\dfrac{total length}{length}[/tex]

Put the value into the formula

[tex]Number\ of\ fabric=\dfrac{243.75}{1.5}[/tex]

[tex]Number\ of\ fabric=162.5\approx 163[/tex]

Hence, 163 fabric needed to make 250 collars.
