A.
Explanation:
why? because the way that the sperm worked it would need help seperatin the ratrianial with the gene and hyprothermiciya! your welcome!! :)
Answer:No
Explanation:Plants will not just have to rely on one animal to help reproduce. Plants can mimic things such as scents or looks to be an incentive for other animals. Wind and water can also help transport pollen. Plants always have pollinators such as wind, water, insects, and animals. Plants use mimicry in order to attract the biotic pollinators. Plants will never have trouble reproducing because they have so many different pollinators.
In the skin, the dermis and hypodermis are richly vascularized by a highly structured blood network of medium and small arterioles, capillaries and venules. Conversely, the epidermis, like any epithelium, is not vascularized; it is nourished by imbibition from the capillary networks of the dermal papillae. Similarly, the lymphatic system is present in the dermis and hypodermis and absent from the epidermis.
In the deep part of the hypodermis, the arteries approach the integument and form a first anastomotic network parallel to the cutaneous surface from which perpendicular branches depart that cross the hypoderm, giving collaterals intended to vascularize the fatty lobules and the appendages: sweat glands and hair follicles. These branches meet in the deep part of the reticular dermis to form a second anastomotic network whose meshes are parallel to the first anastomotic network and the cutaneous surface. From this second anastomotic network, perpendicularly leave arterioles called "arterioles in candelabra" leaving branches for cutaneous appendages and the reticular dermis and eventually anastomosing into a third network located at the junction dermal papilla-dermal reticular. From this last network, leave capillaries that win the dermal taste buds. The venous network is modeled on the arterial model. Arteriovenous anastomoses with or without glomus are found at the nail bed and palmoplantar regions (hands, fingers, feet and toes). They play a fundamental role in thermoregulation.
