In some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." Male ligers ar

e sterile but some female ligers are fertile. In the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. Furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences.

Answer:

a prezygotic barrier

Explanation:

Both wild tigers and lions are said to be reproductively isolated.

Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.

The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.

Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.

<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>

Which zygote would develop into an albino child? Choices are in the picture.
Ber [7]

Ans.

Albinism shows a genetic disorder, which is characterized by absence of coloration or pigmentation in individuals. It is an autosomal recessive disorder that transmits from parents to their offspring, when offspring receives both the mutated copies of gene responsible for albinism.

For a genetic disorder, dominant or wild type allele is represented by capital letter, such as 'A', while recessive or mutated allele is represented by small letter, 'a'. As 4th picture is representing male and female gametes with recessive alleles (a) , the resulting zygote will have both recessive alleles for albinism (aa), '4th zygote will develop into an albino child.'

Which statement about green plants is true?
aivan3 [116]

Answer;

-Green plants are responsible for oxygen in the atmosphere.

Explanation;

-Green plants undertake a process of photosynthesis, in which they use energy from the sun, carbon dioxide and water to form simple sugars and also release oxygen to the atmosphere. The simple sugars from the process may be used by the cells for energy or be stored in form of energy for future use.

-Oxygen is a product of photosynthesis which is released to the atmosphere.

Neurofibrillary tangle in AD are primarily due to mis-folding of what protein?
katen-ka-za [31]

Answer: Tau

Explanation:

NFTs or neurofibrillary tangles are insoluble twisted fibers. The tangles are abnormal accumulation that collect inside neurons. Their presence is also found in other diseases such as tauopathies. Statins have been shown to reduce neurofibrillary tangles in mouse models. Lithium has been shown to decrease the phosphorylation of tau. The tau protein is primary maker Alzheimer's disease.
