Answer:
They are classified into three orders: frogs and toads, salamanders and newts, and caecilians.
Answer:
- According to the cladogram what separates rabbits/primates from crocodiles is that the former have a divergence before the latter and are viviparous.
- The organism that is most closely related to rodents and rabbits in the cladogram is the primate.
Explanation:
The cladogram (see image) shows the evolutionary line that several animal species have followed. According to this, the following conclusions can be established:
- <em>Both primates and rabbits/rodents are mammals, with intrauterine development of their offspring, while crocodiles and birds are oviparous, which represents a </em><em><u>divergence in their evolution</u></em><em>.</em>
- <em>The species most related in the cladogram to rabbits / rodents is the primate, since they share several characteristics in common, such as being mammals, skin covered with hair and being viviparous.</em>
Characteristics such as these are what allow the classification of different animal species.
Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)
In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.
XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.
<span>Biodiversity is the number of species in a particular ecosystem.
It's generally considered more healthy for an environment to have large numbers of species. Many organisms come to depend on others so when you lose one species, it could cause others to be lost.
Example: Several trees in New Zealand required a giant extinct bird the moas to spread their seeds. They lost the trees because they lost the moas.
Hope this helps!! :)</span>
