Answer:
Microfilaments, Intermediate filaments and microtubules
Explanation:
Three distinct elements make up the cytoskeleton in eukaryotic cells are:
1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell, intracellular transport, maintaince of the cell shape..
2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…
3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins), formation of the axoneme of cilia and flagella, formation of the mitotic spindle.
Answer:a) enzymes are responsible for the control of reactions and important in the transfer of energy during photosynthesis .an example is RuBisco ,which catalyse the addition of CO2 to ribulose biphosphate
Chlorophyll; chlorophyll is a photosynthetic pigment that absorbs wavelengths of light
Chloroplast: the chloroplast is a double membrane organelle that houses the chlorophyll.the photosynthetic reaction occurs in the lamellae of the chloroplast while the dark reaction occurs in the stroma
Explanation:
Answer:
D) "I have a history of bleeding ulcers."
Explanation: Diclofenac is a Non-steriodal anti-inflammatory drugs(NSAIDs).
NSAIDs such as diclofenac may result in ulcers, bleeding, or holes in the stomach or intestine and this can develop at anytime when treatment with this drug is on going. It may cause death and symptoms is severe or more pronounced in old people.
Answer:
C. Hypothalamus
Explanation:
Also known as the "thirst center", the hypothalamus controls the autonomic functions like hunger. It regulates temperature and it also holds the "master gland" or otherwise known as the pituitary gland. The pituitary gland controls the functions of the other endocrine glands.
The best answer would be the hypothalamus.
It begins in the mouth. You produce saliva when you chew. This helps break down the food so it can get down to your stomach.
