The answer is <span>A. Dermal tissue, ground tissue, and vascular tissue respectively.
<em>
</em>1. <em>Epidermis is dermal tissue. </em>Dermal tissue covers the plant from the outside. It consists of epidermis and periderm. Epidermis is a single layer that covers young plants.
2. <em>Sclerenchyma is ground tissue.</em> Ground tissue has a variety of functions. It consists of sclerenchyma and parenchyma. The function of sclerenchima is support and strength of roots, stems, and leaves.
3. <em>Phloem is vascular tissue.</em> Vascular tissue has a role in transport of minerals, water, and organic compounds. It consists of phloem and xylem. Phloem transport organic compounds, such as carbohydrates, hormones, etc.

D. It is not under voluntary control
* Skeletal muscle is the only voluntary muscle type
As for my examinations, i would say B. Why? Well, if you would stay out in the sun a lot, you will get cancer, it has ultraviolet radiations, and rays, that is why when you go to the beach, you put on sunscreen, or a hat on.
Hope that this would help you! =)
Answer:
The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.
Explanation:
- You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II
mutation.
- You observe that the response is seen even when no extracellular signal is provided.
- In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.
Answer:
These could be cells taken from any part of the human body
