Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
Inside of plants, there are xylem cells that carry water and minerals from the roots, to the leaves, when the food then gets dispersed to the rest of the plant. This is similar to the human circulatory system but there isn't a heart pumping blood around. Hope this helps :)
Answer:
True
Explanation:
Bacteria generate toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell's surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell.
Answer:
66.6% of the living progeny would be creepers
Explanation:
The creeper allele is Cr for both parents this means that there is a 50% chance that they will pass the C or r trait to their progeny. In this scenario the deleterious inheritance of rr will be 25% so this will not be factored in this answer. The other progeny is CC 25% and Cr 50% for genotype only
The new calculation for living progeny is this: Of the chances of three living progeny there could be one normal CC and two creepers Cr. This means that 33.3% of the living progeny is normal CC and 66.6% of the living progeny are creepers Cr.
According to the question, the amount of the drug administered is 250 milligram (mg). The available dose of the drug is 250 mg per 1.5 mL (milligram). So, for the administration of the 250 mg drug, 1.5 mL of the available drug concentration should be used.
We need to determine the amount of the drug must be drawn in cc (cubic centimeter).
As
So, the amount to be drawn is 1.5 cc.
