Answer:
The defective cell is the M cell. due to the stimulation of Hormone A, cell M produces hormone B in large quantities by inhibiting the production of hormone A by cell D
Hi!
A lizard lies on a rock to raise its body temperature. This is called B. Ectothermy.
Answer:
mucosa
Explanation:
The pharynx and esophagus possesss all of the basic histological layers of the gastrtointestinal tract (GI tract). The layers are:
- mucosa - layer closer to lumen which cocnsists of epithelium, lamina propria and muscularis mucosae
- submucosa-layer of loose connective tissue with vessels
- muscularis propria-layer of inner circular and outer longitudinal muscular layers
- adventia - layer of loose connective tissue
Amoeba and spyrogyra are the two individuals from the Protista kingdom.
Amoeba is single-celled tiny living creatures that primarily live in water. Single adaptable cell repeats abiogenetically by a procedure called binary fission. Amoeba eats green growth and microscopic organisms. Cytoplasm immerses the nourishment source into a sustenance vacuole where chemicals process it. Breath in an amoeba is done by straightforward dissemination of oxygen and carbon dioxide between the amoeba cytoplasm and the encompassing water.
Spyrogyra is a filamentous green growth usually found in water. Spyrogyra contains chlorophyll and uses photosynthesis to make nourishment. Spyrogyra's structure comprises of chain-like long strands of cells. Every cell has a core, cytoplasm, and chloroplast. Propagation happens agamically through fracture or sexually through a procedure called conjugation.
- Rough Endoplasmic Reticulum.
- Chloroplast.
- Cell wall.
- Mitochondria.
- Vacuole.
- Membrane
- Golgi Apparatus.
- Nucleus
- Nucleolus.
The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
- Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.
- Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.
- Cell wall: it is only present in plant cells. It surrounds the membrane.
- Mitochondria: It is the place that generates the energy that the cell needs.
- Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.
- Membrane: it draws the limits of the cell.
- Golgi Apparatus: it is the place where proteins go to be distributed.
- Nucleus: it contains DNA, and it has a membrane around it.
- The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.
To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.
