Answer:
True
Explanation:
Cardiac muscle cells appear striated. However, they are involuntary, unlike skeletal muscle cells, because they contract outside of human control. For example, you do not have to think about contracting your heart muscles as the already contract for you. On the other hand, skeletal muscle cells are controlled by humans as they decide which body movement to perform, such as walking or pointing.

Crossing two true breeding parents with opposite parents is the key:
Assume W is straight wing and w is curly.
Then you are crossing WW with ww
This will result in ALL Ww as offspring - so all straight offspring
If you then cross Ww x Ww you end up with a mix of
WW (1), Ww (2) and ww (1) - so a mix of straight and curly
Answer:
P generation has straight wings and curly wings
F1 has all straight wings
F2 has straight wings and curly wings
Red algae can grow at deeper depths when compared to other algal groups because they are adapted to absorb blue light, which is required for photosynthesis.
Explanation:
Red algae, also known as rhodophyta, usually occur in the depths of seas. This is because of a unique adaptation in their structures, due to the presence of phycoerythrin - a pigment that reflects light that is red, while equipping the algae to absorb blue light. Hence, the algae appears red in colour.
All plants (including algae) require sunlight to be able to synthesize their own food through the process of photosynthesis. For plants that live in the oceans, the sunlight penetrating the waters is the only source of radiation in this regard.
The blue light in the radiation spectrum has the characteristic features of having the highest energy, as well as the shortest wavelength. This makes it the most energetic section of light, enabling it to penetrate to the ocean depths.
The phyrcoerythrin in the red algae absorbs this blue light for photosynthesis. This process occurs even at depths upto 500 feet, hence becoming an adaptive advantage for red algae to be able to survive at greater depths.
