Answer:
The correct answer is - e. many different molecules form a signaling cascade.
Explanation:
Signal transduction is the number of events that take place inside the body of a human from the external atmosphere to transmitting a chemical or physical signal through a number of molecular events of signaling cascade.
The transmission of the particular chemical or physical signal is caused a sequence of phosphorylation events inside the cell it involves specific protein receptors and different types of molecules.
Integral proteins are embedded in the phospholipid layer, and can sometimes form protein channels that let ions and other small molecules through.
Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
You can, but I don't recommend it. Conditioner should only be used for damp or wet hair. If used on dry hair, it could ruin.
Hope this helps!
<h2>The Summer Drought Influence</h2>
The summer drought will influence the model badly because the water is used to make food. Water is the basic need of our life. It is used in everything in our lives like electricity production, washing dishes, and many other activities in daily life. We don’t have enough water means drought and this effect disturbs many people in many activities within various nations.
