<u>Answer:</u>
The type of cells that forms the stratum in the epidermis are basal cells.
<u>Explanation:</u>
- Basal cells have the shape of cuboidal stem cell which forms different stratum in the epidermis.
- There are mainly five stratum layers in the epidermis: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
- All these stratum layers have the basic basal cells as its foundation.
- These basal cells have a special ability to continuously divide and form new cells forming the skin.
Answer:
Plants use carbon dioxide for the process of photosynthesis.
Answer:
D variations in individuals are not heritable
Explanation:
Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.
Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.
Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
Hemoglobin is contained in red blood cells,which efficiently carries oxygen from the lungs to the tissues of the body. It also helps in the transportation of carbon dioxide and hydrogen ions back to the lungs.
