Stating the consequences of drug use is a resistance strategy that can involve __________. A. explaining why the drug is harmful for you B. explaining possible negative side effects of the drug C. explaining how your life might negatively change if you began taking the drug D. all of the above Please select the best answer from the choices provided. A B C D Mark this and return
Answer:
D. all of the above
Explanation:
It is all of them. When we are explaining to someone the consequences of taking a certain drug we can start by explaining to them why the drug in question is harmful to them. Will it ruin their body, their health or others. The drug may have some negative effects that we also need to explain. Telling them how it will ruin their life or their family if they start to take the drug.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.
Answer:
Leaves are always the color they turn in the fall
Explanation:
The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.
I hope this helps and good luck on that two-pager!
Answer:
During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible
Explanation:
What "codes" for proteins that your body uses
to make eye pigment, hair color, hair texture and
etc.?
Proteins
Genes
Phosphate-sugar group
Carbohydrates
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
What are the 4 types of genes?DNA is made up of millions of small chemicals called bases. The chemicals come in four types A, C, T and G. A gene is a section of DNA made up of a sequence of As, Cs, Ts and Gs.
Thus, option "B" is correct.

if a sample contains 20g of an isotope that has a half life of 1000 years how much will be left after 2000 years
After 2000 years, there will be 5g of the isotope remaining.
What is an isotope?If an isotope has a half-life of 1000 years, it means that after 1000 years, half of the original sample will have decayed. After another 1000 years (2000 years total), half of the remaining sample will have decayed, and so on.
To calculate how much of the sample will be left after 2000 years, we can use the following formula:
[tex]N = N_{0} * (1/2)^ (t/T)[/tex]
where:
N = the amount of the isotope remaining after time t
N0 = the initial amount of the isotope
t = the time that has elapsed
T = the half-life of the isotope
Plugging in the values from the problem, we get:
N = 20g * (1/2)^(2000/1000)
N = 20g * (1/2)^2
N = 20g * 1/4
N = 5g
Therefore, after 2000 years, there will be 5g of the isotope remaining.

1.what are three factors that affect the rate of chemical reactions?
2.select one of these factors and describe how it affects chemical reactions within our bodies.
Explanation:
The factors that affects the rate of chemical reactions are;
Nature of reactants Concentration of reactants or pressureTemperature Presence of catalystSunlightIn our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.
The increasing order of food digestion is;
lumps to granules to powder and to liquids.

The plasma membrane is selectively permeable. It allows some substances to enter and leave the cell unrestricted while others are restricted. Some toxins produced by certain bacteria cross the plasma membrane, interfering with normal chemical reactions, and ultimately killing the affected cell. Why are cells unable to stop the flood of these harmful substances into the cell
Answer:
There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.
Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.
The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.
Cell death due to foreign toxins:The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.
They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.
Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.
Answer:
It is possible for their children to either have widow's peak or a smooth hairline.
Explanation:
Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).
A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.
The cross is Ww x ww
W w
w Ww ww
w Ww ww
There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.
So, It is possible for their children to either have widow's peak or a smooth hairline.

The mechanoreceptors sensing light touch are concentrated on
A. the back of the body.
B. hairy skin like forearms and legs.
C. hairless skin like lips and fingertips.
D. the scalp.
Answer:
Hairless skin areas
Explanation:
The mechanoreceptors sensing light touch are concentrated on Hairless skin like lips and fingertips, option C is correct.
Mechanoreceptors sensing light touch are most concentrated on hairless skin regions such as lips and fingertips. These areas have a higher density of specialized touch receptors, known as Meissner's corpuscles and Merkel cells, which are particularly sensitive to light touch sensations. Hairless skin allows for more direct contact with external stimuli, enhancing the perception of gentle touch and fine tactile discrimination.
In contrast, areas with hair, like the back of the body or the scalp, have a lower density of these mechanoreceptors and are more involved in detecting other sensory modalities such as temperature or pain, option C is correct.
