Answer:
A) stratum basale.
Explanation:
The epidermal layer consists of five layers. This is not having any blood vessels and known as avascular. The four-layer starting from stratum basale to stratum corneum is referred to as thin skin. But the skins of foot and palm has another layer called stratum lucidum. This layer forms the five layers of the epidermis.
The stratum basale is the deep layer of the epidermis. Below this layer dermis is present. This layer consists of basal cells which are precursors of keratinocyte cells. The stratum basale is a single layer cell and it undergoes continual mitosis. So that this cell produces new cells and these new cells replace the other older cells above it.
As the basal cells are precursors of keratinocytes, they produce all keratinocytes of the epidermis.
Two other types of cells are produced from this layer - Merkel cell, and melanocyte. Merkel cells act as touch receptors and melanocytes produce melanin pigments.
Coronary artery disease is when plaque in arteries causes blood to not flow correctly or as smoothly as possible. Therefore, a heart attack can occur if blood can't flow.

Answer:
The CO2 acceptor concentration would increase when the CO2 is cut off, but decrease when the light is cut off.
Explanation:
Calvin's light-independent reactions cycle breaks down on three basic stages: fixation, reduction, and regeneration.
All organisms need energy to perform life functions, and energy that is released is reused in other ways. Some plants have evolved mechanisms to increase the CO2 concentration in their leaves under hot and dry conditions.
Answer:
Even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species.
