Answer: Acokanthera schimperi (Arrow Poison Tree) is a species of tree in the family Apocynaceae. It has a self-supporting growth form. It has simple, broad leaves. Arrow Poison Tree is a photoautotroph.
Explanation: The bark, wood and roots of Acokanthera schimperi are used as an important ingredient of arrow poison in Africa. All plant parts contain acovenoside A and ouabaïne, which are cardiotonic glycosides. Its fruit is edible, and is eaten as a famine food. When ripe they are sweet but also slightly bitter. Unripe fruits have caused accidental poisoning as they are highly toxic.[3]
The maned rat spreads the plant's poison on its fur and becomes poisonous.[4]
It is also used in traditional African medicine.[5] In Ethiopia, for example, Acokanthera schimperi leaves have been traditionally used for jaundice.
There seeds are dispersed by,
Other methods of dispersal
Some plants don’t invest much energy in complex mechanisms for dispersal. Bluebells or wild hyacinths (Hyacinthoides non-scripta) are one example of a plant that simply drops its seeds directly to the ground. However, the result is that such plants will tend to spread and colonise new areas very slowly indeed.
Answer:
D. is responsible for most of the skin's structural strength.
Explanation:
A. contains no blood vessels.
False. The dermis contains blood vessels together embedded in it along with the sweat and sebaceous or oil glands, hair follicles, and nerve endings.
B. functions as a padding and insulation.
False. The fat layer that is located below the dermis is the one responsible for padding and insulation.
C. is divided into three distinct layers
False. The dermis is divided into only two separate layers. These are the papillary layer or the upper layer and the reticular layer or the lower layer.
D. is responsible for most of the skin's structural strength.
Yes, the dermis functions for providing the skin's structural strength because of it's thick fibrous and elastic tissue layer. This layer consists primarily of collagen and elastin that also allows for the skin's flexibility.
E. is made of epithelial tissue.
False. The dermis is made up of fibrous and elastic tissue. It is the epidermis which is composed of the epithelial tissue.
Answer:
Sex Cell
Explanation:
A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism. A reproductive cell contains only a single set of chromosomes. Animal egg and sperm cells, the nuclei in grains of pollen, and egg cells in plant ovules are all reproductive cells. Also called gamete, sex cell.
It is mostly likely the cell membrane.
The cell membrane is a structure of a cell composed of double layer of lipids and proteins. It surrounds a cell and separates the cytoplasm from its surrounding environment. The cell membrane is selectively permeable (semi-permeable), which means that it only lets certain molecules enter and exit. It can also control the amount of some substances that go into or out of the cell.
