Answer and Explanation:
Cytokines is the molecule which has the ability to communicate with the immune system cells to target on antigen by generating a response. It is mostly comprised of protein in a group along with peptides.
They are involved in the cancer treatment by production of the signalling molecules that gets involved in the method of stimulating and mobilize the immune system and thus cytokines come into the action for preventing the cancer by providing anti-inflammatory action,anti-cancer cell etc.
<u>Example</u>- In case of ovarian cancer,there is the majority of the immuno-suppressive action and thus there is production of the anti-inflammatory cytokines and thus maintain the immune system.
Answer:
The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).
Explanation:
From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:
- <em>Cell nucleus</em><em>: contains the DNA and is where the transcription into mRNA occurs.
</em>
- <em>Ribosomes</em><em>: where the mRNA is coupled to produce translation and protein synthesis.
</em>
- <em>Rough endoplasmic reticulum</em><em>: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
</em>
- <em>Golgi apparatus</em><em>: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.
</em>
In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.
<em>The options for this question are:</em>
<em> A. Organelles within a cell act independently of each other at all times
</em>
<em> B. Some organelles are more important than other organelles within a cell.
</em>
<em> C. Only up to three organelles may interact with each other at any given moment in time.
</em>
<em> D. </em><u><em>Various organelles within a cell interact with each other to carry out life processes.</em></u>
Limitations on seed production and quality (i.e., germinability) brought on by pollinator abundance or behavior will also have an evolutionary impact, with natural selection favoring the use of pollinators that result in the greatest fitness gain for that population size.
Plants with smaller populations frequently have inferior fruit set due to fewer pollinator visits and less fit progeny as a result of inbreeding. The behavior and ecology of pollinators may have an impact on whether the potentially harmful effects of limited population size are experienced.
Here, we examine how changes in guild composition and pollinator behavior as a function of plant population size affect the fruit set and seed germination of the bird pollinated Angiocaths flavedos (Haemodoraceae). When measuring seed germinability, we utilized a germination stimulant to lessen the possible confounding effects of interpopulation variation in dormancy.
The behaviorally dominating New Holland honeyeaters only frequented big groups, while western spinebills visited all populations sparingly. Regardless of population size, fruit set was extraordinarily high (mean = 96.4 0.6 percent).
Small plant populations appeared to have a lower incidence of hostile encounters interrupting feeding sessions. In certain populations, the percentage of foraging sessions that were stopped reached 31%, which suggests that hostility may regularly encourage pollen migration. In contrast to New Holland honeyeaters, Western spinebills tended to visit fewer stems per plant, a behavior that may favor more outcrossing.
