Plants need three things for photosynthesis to occur: water, carbon dioxide and sunlight. How do those things enter a plant? Water, along with important minerals, enters a plant from the soil where the plant's roots act like straws "drinking" it up. Carbon dioxide enters a plant from the atmosphere, and it comes in through the leaves. More specifically, carbon dioxide enters a plant through tiny pores or openings on leaves called stomata. Sunlight, obviously, comes from the sun. But how does it enter the plant to be converted into chemical energy that the plant can use? Well, green plants are green because of a pigment called chlorophyll. That pigment inside of plant cells absorbs the sun's energy, making it possible for photosynthesis to occur.

A population of rabbits in an ecosystem has genetic variation in fur thickness. Some rabbits have thick fur and others have thin fur. Due to changes in the environment, the average temperature of the ecosystem is steadily increasing.
How will this environmental change likely affect the rabbit population over time?
A. Rabbits with thick fur will become more common in the population because thick fur will be a favorable trait in this changing environment.
B. Rabbits with thin fur will become more common in the population because these rabbits are more likely to survive and successfully reproduce.
C. Rabbits with thick fur and thin fur will become equally distributed because all rabbits in the population will successfully reproduce.
D. Rabbits with both fur types will increase in the population because the temperature change will cause the population of rabbits to expand.
Answers

Sickle-cell anemia is an interesting genetic disease. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause mortality. In addition, malaria cannot survive well within these "partially defective" red blood cells. Thus, heterozygotes tend to survive better than either of the homozygous conditions. If 9% of an African population is born with a severe form of sickle-cell anemia (ss),
what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene?
Answers
The percentage of individuals in the population that are heterozygous (Ss) for the sickle-cell gene will be 18%.
What is population?Population is the total number of people, animals, or other living creatures in a certain area. It is typically measured by counting the number of individuals living within a given territory, and can be used to analyze population growth and density. Population estimates are often used to inform policy and decision making, such as targeted investment in public services, and the use of population data can help to understand economic, social, and health issues.
This is because for each individual with the homozygous recessive genotype (ss), there is another individual with the heterozygous genotype (Ss). Thus, for every 9% of the population with the homozygous recessive genotype (ss), there is an additional 9% with the heterozygous genotype (Ss), making the total percentage of individuals with the heterozygous genotype 18%. This means that 18% of the population will be more resistant to malaria due to their heterozygous condition.

Questions why is the heating in the Benedict's is test and millon test carried out in a water bath
Answers
The heating in the Benedict's test and Millon test is carried out in a water bath to maintain a constant and controlled temperature. This ensures accurate and reliable results by minimizing external factors that could influence the reactions taking place.
The Benedict's test and Millon test are both chemical tests used to detect the presence of reducing sugars, such as glucose, in a given solution. These tests involve a reaction between the reducing sugar and a reagent, which undergoes a color change in the presence of the sugar.
Heating is an essential step in both tests because it helps to facilitate the reaction between the reducing sugar and the reagent. By applying heat, the rate of reaction increases, allowing for faster and more reliable results. However, it is crucial to maintain a consistent and controlled temperature throughout the reaction to ensure accuracy.
A water bath is used for this purpose. A water bath consists of a container filled with water that is heated to a specific temperature, typically around 70-100 degrees Celsius, depending on the test being performed. Placing the test tubes containing the reaction mixture into the water bath allows the solution to be heated uniformly and consistently.
The water bath provides a stable and controlled environment, preventing sudden temperature fluctuations that could affect the reaction rate and, consequently, the test results. It helps to maintain the reaction at the desired temperature for a specified duration, ensuring optimal conditions for the reaction to occur.
By carrying out the Benedict's test and Millon test in a water bath, scientists and laboratory technicians can achieve reliable and reproducible results, allowing for accurate identification of the presence of reducing sugars in a given solution.

Explain how you can prove that photosynthesis occurs in leaves.
Answers
Answer:
Photosynthesis is the process through which green plants (mainly) transform solar energy into useful chemical energy. Plants require energy to grow, reproduce, and defend themselves. Excess photosynthetic energy is stored in plant tissue as starch. Starch is a powdery white material. It stores glucose, which plants utilize for energy. The presence of starch in a leaf is conclusive proof of photosynthesis. This is due to the fact that starch production necessitates photosynthesis.
Explanation:
1. Place one of the plants in a dark room for 24 hours; place the other one on a sunny windowsill.
2. Wait 24 hours.
3. Fill the beaker or jar with ethyl alcohol.
4. Place the beaker or jar in a saucepan full of water.
5. Heat the pan until the ethyl alcohol begins to boil.
6. Remove from the heat.
7. Dip each of the leaves in the hot water for 60 seconds, using tweezers. 8. Drop the leaves in the beaker or jar of ethyl alcohol for two minutes (or until they turn almost white).
9. Set them each in a shallow dish.
10. Cover the leaves with some iodine solution and watch.
The hot water kills the leaf, while the alcohol degrades the chlorophyll, removing the leaf's green hue. When iodine is applied to the leaves, one will turn blue-black and the other will turn reddish-brown. Iodine is a starch indicator that becomes blue-black when it comes into contact with it. The leaf that was exposed to light turns blue-black, indicating that it has been photosynthesising and making starch.
why are enzymes only secreted in specific locations of the digestive system?

Answers
The digestive process is divided into four steps: ingestion, chemical and mechanical food breakdown, nutrient absorption, and expulsion of indigestible food.
What does the digestive process entail?
The digestive process starts as soon as something is chewed. In order for food to pass more easily through your esophagus and into your stomach, saliva, a digestive juice produced by your salivary glands, moistens the food. The carbs in food also begin to be broken down by an enzyme found in saliva.
Motility, digestion, absorption, and secretion are the four fundamental functions of the digestive system. Our digestive system transforms our food into energy that we can use.
The digestive system's initial function is to take in food through the mouth. The "ingesting" procedure must take place before anything else can happen.
