How did Gregor Mendel's research affect the science of his time?

Biology

Rufina [12.5K]2 years ago
7 0

Answer:

The correct option is A. His research was not appreciated by the scientific community until after he died.

Explanation:

Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.

The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.

However, Mendel's study did not include any explanations for polygenic traits. His results could predict heritability in both plants and animals.

oee [108]

Answer:

Gastrulation.

Explanation:

Zygote is formed by the fusion of the male and female gamete. The zygote undergoes the process of cleavage to form the different embryonic stages of the offspring.

Gastrulation is the important process of the pre embryonic development. The blastula get multiply and rearranged to form the gastrula. The gsatrulation process includes the formation of three germ layers also known as triploblastic embryo. The three germ layers are ectoderm, endoderm and mesoderm.

Thus, the correct answer is option (C).

Members of the Deinococcus genus present an interesting conundrum to scientists who try to classify them as either gram-positive
AURORKA [14]

Answer:

Explanation:

Bacteria can be classified traditionally into two broad categories according to their cell wall, which are Gram-positive bacteria and Gram-negitive bacteria.

Gram-positive bacteria are bacteria that produce a positive result when Gram stain test is performed. It takes up the crystal violet stain of the test, and then show a purple-coloured appearance when seen through an optical microscope. This is as a result of the thick "peptidoglycan" layer in the bacterial cell wall which retains the stain used in the cell after washing it away from the rest of the sample.

Gram-negative bacteria after the decolorization don't retain the violet stain,the outer membrane of gram-negative cells is degraded by the alcohol.The peptidoglycan layer is positioned and between the membrane and a bacterial outer membrane, causing them to take up the counterstain and made appear red or pink.

Therefore, Deinococcus is one genus of the bacterial phylum that have resistant to environmental hazards. They posses thick cell walls that give them Gram-positive stains, but they also posess second membrane that made them them closer in structure to Gram-negative bacteria, which present an interesting conundrum to scientists who try to classify them as either gram-positive or gram-negative.
