Answer:
A few modern H. sapiens with some Neanderthal sequences.
Explanation:
The evolutionary study is important to understand the evolution pattern of the organisms and their common ancestors. The human evolution can be revealed by the molecular and biochemicals evidence.
The DNA and protein sequence similarity are used to construct the phylogeny tree. The BLAST tool is used for the alignment of the sequences. The studies suggested that Homo sapiens genome is mixed with that of Neanderthals. This might be possible that DNA sequences of few modern H. sapiens is similar with the Neanderthal sequences.
Thus, the correct answer is option (B).
Answer:
99% water, sodium chloride, trace amounts of wastes, and vitamin C
Explanation:
Eccrine glands are the main and major sweat glands of our body. These glands are found all over the skin but their density is higher on palm, soles, and head.
99% of the secretion of the eccrine gland is water and in rest 1% it contains sodium, trace amounts of waste and a high amount of vitamin C is lost by the eccrine gland.
As the eccrine gland is responsible for sweating so it helps in thermoregulation in the body. As 99% of secretion is water therefore dehydration and water loss is the major worry during excessive sweating.
Answer: Like us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. ... As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.
Homologous structure is type of body structure that indicates evolutionary relatedness.
<h3>What is Homologous structures?</h3>
Homologous structures refers to body structures like organ or bone that have similar underlying anatomical features that exist in different animals. These structures entails that different animals descend from a common ancestor and serve as evidence of evolution.
