Answer:
In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.

What are the advantages and disadvantages of seed and spore reproduction? Justify whether seed reproduction or spore reproduction is more beneficial for the continuation of an organism.
hi have a great day
No Water Required
Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.
Fully Developed Embryo
Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.
Nourishment
Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.
The Seed Coat
The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.

. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

A student is conducting a breeding experiment. She knows the genotype of one parent plant and concludes that she can use a Punnett square to predict the outcome of crossing the plant with another plant. Which statement best explains why this conclusion is incorrect?
a. She needs to know the phenotypes of the previous plant generation.
b. She needs to know the phenotype of the first plant.
c. She needs to know the genotypes of the previous plant generation.
d. She needs to know the genotype of the second plant.
D. She needs to know the genotype of the second plant.
What is a punnett square?A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.
Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

Answer :
Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.
