Answer:
a mouthpart that can pierce fruits and seeds
Explanation:
An adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms. That being said the most likely morphological change that would trigger this would be a mouthpart that can pierce fruits and seeds. This new change would allow the beetles to consume most of the different resources that the island has to offer such as the different types of plants and fruits which were previously inaccessible to the beetles.

Answer:
Lactic acid fermentation
Explanation:
When sugars are broken down to energy and lactic acid in animal tissues and in microorganisms it is referred to as lactic acid fermentation. Unlike alcoholic fermentation, lactic acid can be further broken down to release the locked up energy should oxygen be made available.
Answer:
The probability of their first child being colourblind is 1/4
Explanation:
Red-green color blindness is an X-linked recessive disorder.
A woman with normal vision whose father was colorblind has children with a man with normal color vision.
In an X-linked condition, the males only need to get one copy of the affected allele to have the condition and this copy is also inherited by a female offspring.
So in this case, the woman receives the affected recessive allele copy from her dad but since she still has normal vision, she received the normal copy from her mom so she is heterozygote for the trait.
The woman with normal color (XRXr) has a father who is color blind (XrY) has children with a normal man (XRY)
The cross would be
XRXr x XRY
XR Xr
XR XRXR XRXr
Y XRY XrY
Probably of having an affected child is 1/4. Thus, the probability of their first child being colourblind is 1/4
