During which period is the substance changing state?
A. During the time labeled C, when the temperature increases
sharply.
B. During the time labeled E, when the temperature increases for a
third time.
C. During the time labeled A, when the temperature first starts to
increase.
D. During the time labeled D, when the temperature stays the same.
SIDANT
Answer:
[tex]\boxed {\boxed {\sf D. \ During \ the \ time \ labeled \ D, \ when \ the \ temperature \ stays \ the \ same}}[/tex]
Explanation:
Phase changes have to happen at a specific temperature. During a phase change, the energy is used to make the change happen, instead of raising the temperature.
On a graph, a constant slope, or in this case temperature, is a flat line. On this graph, the flat lines are at B and D.
There is no answer including B, but there is for D.
Choice D: During the time labeled D, when the temperature stays the same is correct.
A unicellular protist that carries out the process of photosynthesis would be classified as a...
1) producer
2)saprophyte
3) predator of green algae
4) decomposers of inorganic compounds
Answer:
1) THIS WOULD BE CLASSIFIED AS A PRODUCER.
A unicellular protist that carries out the process of photosynthesis would be classified as a producer.
PRODUCERS:
A producer in an ecosystem is an organism that possess the ability to synthesize their own food. Producers make use of photosynthesis (light energy) or chemosynthesis (chemical compounds) to synthesize their energy source. The energy production that is initiated by producers is transferred in the ecosystem when they are fed on. Examples of producers are green plants, photosynthetic bacteria, algae etc. Therefore, a unicellular protist that carries out the process of photosynthesis would be classified as a producer.Learn more at: https://brainly.com/question/20310424?referrer=searchResults

What is the role of ATP in the process of active transport?
Answer: ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Hope this helps... stay safe and have a great weekend!!! plz mark brainliest if i am right...
The role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.
Active transport is the transport process where carrier proteins pick up specific molecules and take them through the cell membrane against the concentration gradient.
This transport requires cellular or metabolic energy which is available in the form of ATP molecules produced within the cell.ATP plays a critical role in the transport of macromolecules such as proteins, lipids, and ions into and out of the cell.The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.Thus, the role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.

Phenylketonuria (PKU) is a disease that results from a recessive gene. Two normal parents produce a child with PKU. What is the probability that a sperm from the father will contain the PKU allele?
a. 2/3
b. 3/4
c. 1/3
d. 1/2
e. 1/4
Answer:
d. 1/2
Explanation:
According to this question, PKU (Phenylketonuria) is a recessive condition in humans. A normal human must possess at least a dominant allele in the gene.
In a situation where two normal parents produce a child with PKU. This means that both parents are heterozygous for the condition i.e Pp × Pp. Hence, the heterozygous male (Pp) will produce gametes in the following proportion: P (1/2) and p (1/2).
This means that the probability that a sperm from the father will contain the PKU allele (p) is 1/2 or 50%

Read the information for transcription and then answer the question.
Protein Synthesis
Explain the process of transcription
Answer:
Protein synthesis is the process which synthesizes proteins by the information coded in the DNA molecule with the help of two distinct process takes place in order namely transcription and translation.
Transcription is the first process of the central dogma or the protein synthesis that produces mRNA molecule that carries all the information stored in the DNA molecule out of the nucleus (in eukaryotes only) to the ribosome where the second process Translation takes place.
Untwists then unzips of DNA molecule is catalyzed by RNA polymerase result in the Hydrogen-bonds between the strands break .
Creates complementary base pairs with bases of the DNA strand with help of free RNA nucleotides
weak hydrogen bonds and sugar-phosphate bonds form between base pairs and RNA nucleotides respectively
mRNA strand is synthesized and peels off the DNA and transported or pass from the nucleus to cytoplasm

what is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly
Answer:
8%
Explanation:
Given that,
Mass of solute = 8 g
Mass of soultion, (mass of alloy) = 100 g
We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :
[tex]\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%[/tex]
So, the percent by mass is 8%.
The percent by mass of the given copper in the alloy formed is 8%.
The given parameters;
mass of the copper = 8 gmass of the copper-zinc alloy = 100 gThe percent by mass of the given copper in the alloy formed is calculated as follows;
percent by mass of zinc = [tex]\frac{mass \ of \ zinc}{mass \ of \ the \ alloy} \times 100\%[/tex]
percent by mass of zinc = [tex]\frac{8}{100} \times 100\%[/tex]
percent by mass of zinc = 8%
Thus, the percent by mass of the given copper in the alloy formed is 8%.

A. Anterior and posterior
B. Posterior and superior
C. Anterior and superior
D. Posterior and inferior
The anatomical directions that are opposites of each other are: Option D. Posterior and inferior . Anatomical directions refer to a standard frame of reference used to describe the locations and orientation of body structures.
The following anatomical directions are opposites of each other:Anterior (front) and posterior (back): These are opposites and refer to the front and back sides of the body. The front side of the body is the anterior side, whereas the back side of the body is the posterior side.
Superior (upper) and inferior (lower): These are opposites and refer to the upper and lower portions of the body. The upper side of the body is the superior side, whereas the lower side of the body is the inferior side. Medial (towards the midline) and lateral (away from the midline):
These are opposites and refer to the sides of the body. The side of the body that is closer to the midline is the medial side, whereas the side of the body that is further away from the midline is the lateral side. Proximal (closer to the trunk) and distal (further away from the trunk):
These are opposites and refer to the position of limbs or body parts relative to the trunk. The part of the limb or body that is closer to the trunk is the proximal part, whereas the part of the limb or body that is further away from the trunk is the distal part. Option D is correct.
