Blood type O is gene recessive
Yes, you're correct, it's the first one. He should do research before he does an experiment, because someone else may already know.
Answer:
4. Absorb extra fluid between the cells
Explanation:
The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.
If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:
- <em>CENTRAL VACUOLE
</em>
- <em>plasma membrane
</em>
- <em>
cell wall
</em>
- <em>
chloroplast</em>
The correct answer as to which of the organelles the cell must have would be the plasma membrane.
- central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
- All cell types have plasma membrane.
Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.

In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
