Answer:
Blood
Explanation:
Connective tissue consists of extracellular matrix and cells. The main function of connective tissue is to bind the other tissues together, provide them support and strength. Blood is one of the liquid connective tissue that does not perform such functions. The presence of liquid extracellular matrix (plasma) and formed elements (blood cells) makes it a connective tissue. It serves in the transport of nutrients, gases, wastes, hormones, etc. It also takes part in immune responses but does not strength or support other body tissues.
Answer and Explanation:
The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.
Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.
The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.
The answer is D. corals are imperative to damage
Answer: Option A
Explanation:
An endosperm is defined as the tissue which are produced inside the seeds during fertilization. As the endosperm surrounds the embryo, it acts as the food storage for the embryo and provide nutrition.
During embryo development , endosperms supports enlargement of cotyledons which helps in storage function and stores fats and starch and provide nourishment to the embryo.
for example cereal crops or grains are primarily endosperm which stores fat and starch and are edible fruits.
Hence, the correct option is A, endosperm can be a cotyledon which functions as a source of food for embryo.
