Answer:
The dependent variable measured in the researcher’s experiment is the concentration of the drug in the blood samples. One control that the researcher could use to improve the validity of the experiment is to ensure that the same amount of the drug is administered to each participant.
Analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period allows the researcher to track changes in the concentration of the drug over time. This gives a more accurate picture of how the drug is metabolized by the body and how it affects the participants.

Comment on the difficulty of describing a virus as a living organism.
Answer: You can't describe a virus as a living organism...it's not living!
A virus needs a host to survive and replicate itself to create a illness. It invades a cell by attaching itself onto it and injects its DNA into the cell. Afterwards, the cell bursts and creates the new virus replica. Every cell that is affected by a virus always dies.

Which substances are needed for cellular respiration?
Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration. (10 points)
Chemical reactions that simulate cellular respiration follow the Law of Conservation of Matter when they are balanced. Six carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms are the same number of atoms as the reactants. C₆H₁₂0₆+60₂ — 6C0₂+6H₂0 .
What is cellular respiration?Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste. Foods are broken down by organisms that do not require oxygen in a process known as fermentation.
What are atoms?A chemical element is uniquely defined by its atoms, which are small units of a substance. An atom is made up of a core nucleus and one or more negatively charged electrons that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present. The fundamental building components of matter are atoms. Atoms make up anything that has mass and occupies space.

2. Coastlines are continually eroded by what
process? sc.6.E.6.2
A longshore currents
B parallel shore currents
C shortshore currents
D perpendicular shore currents
???????????
Coastlines are continually eroded by longshore currents, which are currents that flow parallel to the shoreline. These currents can be caused by the wind and waves, and they can transport sediment (such as sand and gravel) along the coast. As the sediment is moved and deposited, it can cause the coastline to change shape and erode over time.
Answer:
Explanation:
Coastlines are continually eroded by longshore currents.
Longshore currents are ocean currents that flow parallel to the shoreline. They are created when waves approach the shore at an angle, and the water is deflected by the friction of the bottom and the shape of the coastline. The resulting current flows parallel to the shore, and can cause erosion of the coastline over time.
Parallel shore currents and shortshore currents are not correct terms. Perpendicular shore currents are not a natural phenomenon and do not occur in the real world.

Answer:
b. Altered chromosomes.
c. Changes in cell surface molecules.
e. Integration of viral deoxyribonucleic acid (DNA) into host chromosome.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles found in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Transformed cells refer to cells that have undergone genetic alterations and as such do not experience normal cell processes or characteristics such as differentiation, division, and growth.
The characteristics which are typically associated with transformed cells include the following;
I. Altered chromosomes. Chromosomes are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
II. Changes in cell surface molecules.
III. Integration of viral deoxyribonucleic acid (DNA) into host chromosome.

What is the end result of mitosis?
A) one cell with two identical copies of DNA
B) two cells with different copies of DNA
C) one cell with two different copies of DNA
Answer:
A) one cell with two identical copies of DNA
Explanation:
The end result of mitosis is one cell with two identical copies of DNA.
Answer: A) one cell with two identical copies of DNA
Explanation: Mitosis is a process of cell division that occurs in somatic cells (non-reproductive cells). It involves a series of steps that result in the formation of two identical daughter cells.
During mitosis, the parent cell undergoes several stages: prophase, metaphase, anaphase, and telophase. In prophase, the DNA condenses into visible chromosomes, and the nuclear membrane begins to break down. In metaphase, the chromosomes align in the middle of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the nuclear membranes reform around each set of chromosomes, and the cell begins to divide.
At the end of mitosis, each daughter cell contains the same number and type of chromosomes as the parent cell. This means that each daughter cell has an identical copy of the parent cell's DNA. The division of the cytoplasm then occurs in a process called cytokinesis, resulting in two separate daughter cells.

describe the climate in coastal area near a warm ocean current
Answer:
The climate in coastal areas near a warm ocean current has higher temperatures as its moving away from the equator. The warm ocean currents cold water sinks which then allows light warm water to flow to the opposite direction usually away from the equator.

The climate in coastal area near a warm current will warm and rainy. The coastal regions will be maintained in a moderate temperature by warm current
What is warm ocean current?
Warm currents are heat transferring wind flowing from ocean parallel to the tropical and sub-tropical regions. Warm ocean current results in summer rainfall in the surrounding areas.
North Atlantic drift and Canary currents are examples of warm ocean currents. They are responsible to bring a moderate temperature level in coastal areas.
Warm ocean currents may sometimes mix with cold currents creating foggy weather in the near areas. Thus cold and dry climate may result in that areas.
Therefore, in general, warm ocean currents make the surrounding coastal areas in a moderate temperature with summer rainfall.
