I think at 15 days because that is when it goes down
Answer:no. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.
Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent
Gene cloning produces copies of genes or segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Gene cloning, also known as DNA cloning, is a very different process from reproductive and therapeutic cloning. Reproductive and therapeutic cloning share many of the same techniques, but are done for different purposes.
Explanation:
Answer: c
Explanation: Stomata are present on the stem and the leaves of the plants. These are tiny pores in the skins of the stem or the leaves. Plants take carbon dioxide through these stomata and gives oxygen through these pores. So this is the correct answer.
Outdoor CO2 levels are frequently as low as 400 ppm, whereas interior CO2 levels typically vary from 420 to 1000 ppm. CO2 values under 1000 ppm are considered healthy levels. The best way is to open all the windows of classroom.
What are the health risk of high CO₂ level?
- People may have moderate symptoms like sleepiness, restlessness, an accelerated heart rate, and breathing difficulties if levels exceed 1000 ppm.
- This is particularly problematic in educational settings when learning new material calls for increased focus and attention from students.
- In addition to causing significant discomfort, levels of CO2 above 2000 ppm prevent pupils from functioning at their best in class and, over time, impair the growth of their cognitive abilities.
- In addition to the above described symptoms, there are others including nausea, poor focus, and feeling stifled.
- Indoor CO2 levels are normally below 1000 ppm, but if there are more than 20 pupils and teachers in a closed space, the CO2 levels will naturally rise, and it is not unusual for them to exceed 3000 ppm.
