Answer:
A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
Hence, the correct answer is "A)"
Answer:
a. salivary amylase
Explanation:
salivary amylase breaks down starches (complex carbohydrates) into sugars for the body to absorb more efficiently.
The correct answer is option (A) Chlamydia.
A typical sexually transmitted illness is chlamydia. Both men and women are susceptible. However, compared to men, women are typically more negatively impacted by its consequences.
Symptoms and reasons for Chlamydia
- Chlamydia symptoms are sometimes mistaken for those of other diseases that afflict women.
- Some signs, such vaginal ulcers, are difficult to see, making the infected unaware that they have the disease.
- If addressed, this can result in even more serious issues including pelvic inflammatory disease, which then might have an impact on fertility.
- It may harm a woman's reproductive system permanently. Later it becomes challenging for women to get pregnant as a result. Additionally, chlamydia can result in an ectopic pregnancy that may be fatal.

The force between them if the distance between them is doubled is a. F/4
Explanation:
- To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
- The equation can be written as,
where k is the Coulomb constant, 
are the point charges, and r is the distance between these two point charges. - To find the answer to this question, just substitute 2r in the place of r hence, you will get
as the new force when the distance is doubled.
Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>
