Answer:
Ability to perform locomotion with their legs
Explanation:
Plants and animals are two distinct species of organisms. Plants are capable of using photosynthesis to obtain their food due to the unique structures that can capture light energy in their cells (autotrophic). Animals, on the other hand, are heterotrophic i.e. cannot perform photosynthesis and therefore, rely on other organisms for food.
Since animals depends on eating other organisms to obtain food/energy, their possession of LEGS or ability to LOCOMOTE is very instrumental to their success as non-photosynthetic or heterotrophic organisms. This enables them leave one position in search for food and resources
You didn't give any answer choices (i'm answering this through research and what i already know)
the first is fossilized dung, and that's not generally gastropod shells. A carbon film would be something thin, seeing as it's a film, and gastropods aren't that. A gastrolith is a stone swallowed by an animal to help with digestion, and that's also not a gastropod.
<span>Gastropod fossils may be molds, but usually aren't. Still, they can be. It's a better answer than; film or stomach stones.</span>
Answer:
A single gene on the Y chromosome plays a crucial role in the parental development of the testes.
Explanation:
Y chromosome is present only in males and this chromosomes is the distinguishing factor which separates males from females. It is the smallest chromosome but of utmost importance due to its sex determining feature. Up till now, studies show that Y chromosomes only carry limited amount of genes.
The Y chromosome, most importantly, comprises of the SRY gene. This is the gene responsible for determining the testis and for the development of the testis. The SRY gene is responsible for sex determination.
Answer:
