Answer:
Considering the <u>whole progeny</u> (100%), there will be
- 25% Black male kittens, XBY
- 0% Calico Male kittens
- 25% Calico female kittens, XBXR
Explanation:
<u>Available data:</u>
- The gene for Calico (multicolored) cats is an x-linked trait and codominant
- Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
- Males can only be black or orange, but never calico. Their genotype is XBY and XRY

Parentals) XBXR x XBY
Gametes) XB XR XB Y
Punnett square) XB XR
XB XBXB XBXR
Y XBY XRY
F1) Among the whole progeny:
- 2/4 = 50% will be black (female XBXB and male XBY)
- 1/4 = 25% will be Calico (female XBXR)
- 1/4 = 25% will be Orange (male XRY)
Among females:
- 1/2 = 50% of females will be black, XBXB
- 1/2 = 50% of females will be Calico, XBXR
Among males:
- 1/2 = 50% of males will be black, XBY
- 1/2 = 50% of males will be orange, XRY
Answer:
Biotic: <em>Food availability</em>
Abiotic: <em>Temperature</em>
Explanation:
There are two types of limiting factors for biodiversity: biotic and abiotic. Biotic refers to living things, for example, organisms that are an important food source. <u>Most animal life forms in the ocean highly depend on the availability of a food source</u>. If food is limited or scarce, the populations of a given species could face significant declines.
On the other hand, there are abiotic factors, which refer to factors that are not alive, such as physical factors. For instance, temperature and light. <u>For marine organisms, temperature is a critical factor.</u> Even an increase of 'only' 1 ºC could make a huge difference in the survival of a species as it could disrupt their ability to forage, hunt, or perform physiological processes, <em>e.g.</em> metabolism.
Therefore, <u>if we refer to a biotic factor, food availability is a limiting factor for most animal life in the open ocean, whereas, if the refer to an abiotic factor, temperature (and light) are limiting factors for pelagic life.</u>
I am guessing its the chlorophyll. <span />
NH3 since they are both non metals
