Using the idea of a concentration
gradient, explain why the blue
colour gradually spreads throughout
the water in the jar. When does
diffusion stop?
Answer:
Explanation:
Osmosis. Osmosis is the diffusion of water through a semipermeable membrane down its concentration gradient. If a membrane is permeable to water, though not to a solute, water will equalize its own concentration by diffusing to the side of lower water concentration (and thus the side of higher solute concentration).

A strand of DNA has these bases: AGC CAT GTA TAC
What is the complementary DNA strand?
A. ACG GAT CTA TAG
B. TCG GTA CAT ATG
C. TGC CTA GAT ATC
D. UCG CỦA CAU AUG
Answer: The answer is c
Explanation:
DNA replication is semiconservative and at such, complementary base-pairing ensures that if adeinine is found on one strand, thymine is found on the other, and if guanine is found in one strand, cytosine is found on the other. complementary base pairing also helps to hold the double helix together by the formation of hydrogen bonds.
The correct answer is (B) TCG GTA CAT ATG
What is DNA?DNA is a double helix structure with two strands entwined together having complementary base pairs one purine and another for pyrimidine. It has all the required information for protein synthesis.
What is complementary base-pairing?Adenine (A) and Thymine (T) are complementary base pairs and Cytosine (C) and Guanine (G) are also complementary base pairs.
Why other options are incorrect?The option A has adenine as first in the sequence which is not complementary to the one given in the question. The option B had second base pair is guanine which is not complementary to the sequence in questionIn the option D has Uracil as first base pair which is not a part of DNA strand. Uracil is present only in RNA.So, option B is correct with complete complementary sequence of the question.

A. Using genetically engineered crops
B. Spreading pesticides with planes
C. Increasing the number of vertical farms
D. Increasing the number of rural farms
Answer: Spreading pesticides with planes
Explanation: The use of pesticides has allowed the world’s food production to expand greatly over the last century. However, the chemicals in pesticides can be dangerous to humans and animals.

What things do humans do in the flower garden that alter the biotic elements of
the ecosystem? What effects do they have on biodiversity?
Answer:
Humans often use pesticides to destroy undesirable organisms that live in flower gardens, such as insects, weeds, or fungi. The use of such chemicals will reduce biodiversity. Humans also plant many of the same plants in gardens, which reduces biodiversity.
Humans perform different functions in the flower garden that alter the biotic elements of the garden, which include the usage of most of the pesticides that affect the soil and the microorganisms present in it, the planting of non native species, etc.
What is the significance of human interference in the garden?Human interference in the garden has many negative impacts, such as the introduction of non-native plant species to a garden, which can lead to the replacement of native plants, excess watering and fertilizing lead to an overgrowth of certain species and create an imbalance that changes the naturalness of the garden.

Diabetes is often suspected when glocose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptoms is especially concerning for young people?
Answer:
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.
Explanation:
answer for plato, if your gonna use please change the wording, so it sounds like you typed it up instead of coping and paste.
The represented model shows the below mentioned steps:
Step 1: Blood goes to the kidney for the process of filtration and if excess sugar other than normal is present in the blood, the filtered substance will have much sugar as compare to the person who does not have diabetes.
Step 2: The model shows that there is some reabsorption of sugar but there is unusually more amount to filter, some sugar will remain in urine as it passes through the renal tubule to be excreted by the body.
This symptom is required to be concenred because it could create a stress on kidney, which will lead to kidney related problems at young age.
What is diabetes?Diabetes is a disease in which the glucose present in the blood is not converted into glycogen due to less production of insulin hormone.
The main symptoms or early sign of diabetes are feeling hunger and fatigue, dry mouth and itchy skin as well as feeling thirsty other than normal.

Step 1: Blood goes to the kidney for the process of filtration and if excess sugar other than normal is present in the blood, the filtered substance will have much sugar as compare to the person who does not have diabetes.

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.We breathe oxygen from the air into our lungs, and we breathe out carbon dioxide, which is formed in our body as a waste gas. Breathing is essential to life itself. Oxygen must pass from our lungs into our blood for our tissues and organs to work properly. We require Oxygen to live.

Cells contain small specialized structures called___________that act just like organs in your body
Answer:
Organelles
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
Cells contain small specialized structures called organelle that act just like organs in your body.
What are cell organelles?An organelle is a subcellular structure that, like an organ, has one or more specific jobs to do in the cell.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.
The major organelles and cellular structures found within the cytoplasm include the nucleolus, nucleus, ribosome, vesicle, rough endoplasmic reticulum, Golgi apparatus, cytoskeleton, smooth endoplasmic reticulum, mitochondria, vacuole, cytosol, lysosome, and centriole.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.
Thus, the answer is cell organelle as it acts like organs acting in the human body.
