Meiosis I produces two cells, both of which are haploid. This means each cell has half the number of chromosomes as the parent cell. This is a crucial step in sexual reproduction, promoting genetic diversity.
Meiosis I produces two cells, each of which is haploid.
During the process of meiosis, a cell initially has two copies of each chromosome, one from the mother and one from the father (46 in humans). This is called a diploid state. However, after meiosis I, it splits into two cells each containing half the number of chromosomes (23 in humans). These cells are said to be haploid because they only possess one copy of each chromosome. The division which occurs during meiosis I is a fundamental part of the sexual reproduction process, as it leads to genetic diversity in offspring.

2. producing a new drug to lower blood pressure
3. researching the relationship between exposure to UV rays and skin cancer
4. all of the above
Answer: 3. researching the relationship between exposure to UV rays and skin cancer.
Explanation:
Applied research is an application based research as it utilizes the knowledge of scientific literature to solve the problems related to science. It is based upon the experimental procedure to find the cause of a natural phenomena.
Researching the ralationship between exposure to UV rays and skin rays. is the correct answer because it can be observed on the basis of experimental procedures the impact of UV under control conditions over the skin.
Evaluating the effectiveness of chemotherapy, producing a new drug to lower blood pressure and researching the relationship between exposure to UV rays are all examples of applied research. The correct option is D.
Thus, scientific explorationthat is carried out specifically to address practical issues or enhance existing conditions is referred to as applied research. Studying and examining the effects and results of a medical procedure in a clinical context is necessary to assess the efficacy of chemotherapy for cancer patients.
Creating and testing a pharmaceutical substance with the goal of treating a medical condition is necessary to create a new blood pressure-lowering medication.
In order to adopt preventative measures and public health interventions, research on the association between exposure to UV radiation and skin cancer tries to learn more about the relationship between UV radiation and the emergence of skin cancer.

To reproduce, organisms need to release energy from energy storage molecules. If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase.
The moon jelly is one of the most common jellyfish in Rhode Island. Its body shape resembles an umbrella, with four equal-sized horseshoe-shaped gonads in the center of its body. Moon jellies are made up almost entirely of water and will not hold their shape when out of the water.

Explanation:
a. True
b. False
Answer:
a. True
Explanation:
Proteins are biopolymers composed of amino acids that appear in chains. These amino acids are formed by peptide bonds. Due to the functions they carry out, proteins are essential for the existence of life. Proteins can be found in both animals and vegetables. In animals, there are proteins that help protect the body, others are in charge of regulating metabolism. On the other hand, in plants proteins participate in cell division processes, membrane transport, catalysis of biochemical reactions, photosynthesis and respiration processes, synthesis of sugars, starches, and other compounds.
True. Protein can be found in both animals and vegetables. Therefore, option (A) is correct.
All living species need amino acid-based proteins to shape, function, and regulate their cells and tissues. Meat, poultry, fish, eggs, and dairy are protein-rich. These sources often supply all needed amino acids.
Proteins in vegetables and plant-based diets differ from animal-based proteins. Plant-based protein sources include legumes, soy, nuts, seeds, and grains like quinoa and amaranth. A balanced amino acid profile can be achieved by eating a variety of plant-based proteins. Therefore, option (A) is correct.

If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.
