Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
Answer:
C. petals
Explanation:
A)fruits
B)sepals
C)petals
D)anthers
E)ovaries
<em>The part that will not be necessary in wind pollinated angiosperm is the petals .</em>
The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.
<u>Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).</u>
Hence, the correct option is C.
I recommend reading a passage about it. Hope this helps!
A point mutation affects a single base and most commonly occurs when one base is substituted or replaced by another. Frameshift mutation results from the addition of one or more bases, known as an insertion, or the removal of one or more bases, known as a deletion.
