Answer ;
Phagocytosis is when smaller organisms or other food particles are eaten.
Autophagy is when a damaged organelle or small amount of cytosol becomes surrounded by a double membrane and a lysosome fuses with the outer membrane of the vesicle.
Enzymes break down the material. Food vacuoles fuse with a lysosome, whose enzymes digest the food.
Explanation;
-The Lysosomes are organelles that are responsible for intracellular digestion. Lysosomes are vesicles that contain hydrolytic digestive enzymes capable of breaking down large molecules into smaller ones.
-There are several ways in which different varieties of macromolecules may be digested by lysosomes. One mechanism is phagocytosis, the other is autophagy, which entails the removal of membrane-bounded organelles or other cytoplasmic components through the action of lysosomes, and lastly the hydrolytic enzymes may break down or digest the unwanted materials.
Answer:
It would be difficult to recreate the exact conditions of the chemical release elsewhere.
Explanation:
Answer:
Wind
Explanation:
Gymnosperms can be described as plants which lack flowers and fruits.
As they do not have flowers to attract insects like the angiosperms, they can, however, transfer their pollen through the wind. As pollen is very light in weight hence, it can be transported by the wind. The pollen transported by the wind usually results in self-pollination as the wind is not able to take the pollen to long distances.
Answer:1.c 2.d 3. d
Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
Answer: exocrine glands
Explanation: Exocrine gland secrete substances to an epithelial surface through a channel.
The sebaceous and sweat glands associated with the skin also secrete substance to skin surfaces via ducts/ channels and are classified as endocrine gland. There are two glands in the human body Exocrine gland and Endocrine gland.
Endocrine gland secrete substance into the bloodstream directly. Examples of exocrine glands are sweat, salivary, mammary, sebaceous, and mucous.
liver and pancreas are both exocrine and endocrine glands simultaneously.
As exocrine gland, the liver secrete bile and the pancrease secrete pancreatic juice into the gastrointestinal tract through channels. While as endocrine gland they secrete other substances directly into the bloodstream.
