Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so
Answer:
False
Explanation:
It is found that birds have evolved in the Mesozoic Era from a a group of theropod dinosaurs. the most close relative of modern day bird was supposed to be a primitive bird known as Archaeopteryx. In a recent study conducted by UCMP Berkeley, birds have common ancestors from the theropod lineage. More specifically, lizard-hipped dinosaurs are ancestors of birds.
Hence, the given statement is false
It would result in reducing the sunlight it’s getting, so it would be harder for photosynthesis to take place
