Answer:
agcttgagt
Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".

Newton's first law of motion states that an object will remain in motion in a straight line unless compelled to change direction by an external force.
Explain why satellites launched into orbit do not continue moving in a straight line. Make a connection between satellites and planets.
Explanation:
When satellites are launched into orbit, they are able to orbit around planets due to the gravitational force of attraction between the satellite and planet (usually there is no apparent change in motion of the planet because of its relative huge size than the satellite)
This gravitational force is in a different direction than the satellite's motion, therefore it keeps it orbiting around planets and does not continue moving in a straight line.

Which is a reactant in the Calvin cycle?
A. Glucose
B. Oxygen
C. Carbon dioxide
D. Water
The reactant of the Calvin cycle is the carbon dioxide that is present in Option C, and the product of the Calvin cycle is glucose. The Calvin cycle takes place during the photosynthetic reaction.
What is the role of photosynthesis?Photosynthesis is a process in which the plant plays an important role, such as when the plant absorbs the sun's light, water, and carbon dioxide and then produces oxygen and glucose by combining all of these elements; thus, glucose and oxygen are the products, and water and carbon dioxide are the reactants. The water is used in the light-dependent reaction and converted into oxygen as a product, while in the case of the Calvin cycle or the light-independent reaction, carbon dioxide is used as the reactant and the product that is formed is glucose.
Hence, the reactant of the Calvin cycle is the carbon dioxide that is present in Option C.

Which substance increases its volume when it becomes a solid?
A. Mercury
B. Water
C. Salt
Answer:
B
Explanation:
when water is frozen, it expands, something to do with anomolous expansion of water.
Water increases its volume when it becomes a solid.
Define volume and its units?Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
The surface-area-to-volume ratio, also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects.
If volume is the amount of 3-D space contained by a closed surface (e.g. the amount of space within a given cube, or cylinder, or any other 3-D shape), liquid volume is a way to measure an amount of liquid by describing it how much 3-D space it occupies.

5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c. determine how a star is moving (toward, away, fast, slow) d. all of these e. none of these
Answer:
The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
Why do people feel fireworks before hearing it?
Answer:
People feel fireworks before hearing it because light travels faster than sound.
Explanation:
We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

Which of these is one characteristic of topographic maps? A mountain peak. B location of a ravine. C steepness of a slope. D distance between two areas.
Steepness of a slope (C) is one characteristic of topographic maps.
"The more closely spaced the contour lines, the steeper the slope. You can find out exactly how steep the slope of the area you are interested in by subtracting the lowest elevation from the highest, and dividing the result by the horizontal distance."
HELP ASAP PLEASE!! DUE IN 10 MINUTES !!! based on these results which statement correctly predicts what will happen to red blood cells when they are placed in a beaker containing a water solution in which the salt concentration is much higher than the salt concentration in the red blood cells
A:the red blood cells will absorb water and increase in size
B:the red blood cells will lose water and decrease in size
C:red blood cells will of first absorb water than lose water and maintain their normal size
D:the red blood cells will first lose water then absorb water and finally double in size
Answer:
The correct answer is - option B. the red blood cells will lose water and decrease in size.
Explanation:
The movement of the water takes place always from the high concentration region of solute to the low concentration of solute through a semi-permeable membrane. In this case, the representation is showing that placing the cell inside a solution with low concentration solute than the cell makes the cell increase the size, and placing it in a solution high concentration of solute makes it decrease in size due to the transfer of water from more water to the low water area.
Now placing the RBC in a solution with more salt concentration than the cell makes the solution hypertonic which means the solution has more solute concentration and less water so the water move from cell to the solution and cell will shrink and decrease in size.
Genetics is defined as: Group of answer choices The scientific study of cells The study of cloning The scientific study of heredity The dividing of cells
Answer:
The correct answer is ''The scientific study of heredity''
Explanation:
Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.
Many small freshwater organisms have a structure called a contractile vacuole, which pumps water out their body. Explain how this process is an example of active transport.
Answer:
1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.
2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

tracking the history of the earth.
PLEASE ONLY ANSWER IF YOU KNOW-
Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
