Answer:
India was a separate continent until 45 million years ago
Explanation:
India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.
Answer:
The correct answer is - 6.8950.61 gm per mole
Explanation:
Given:
One form of hemoglobin is 0.324% Fe by mass
1 hemoglobin = 4 Fe
Solution:
Molar Mass of iron = 55.85
mass of 4 iron atom = 55.85 * 4 = 223.4 gms
0.324 % correspond to 223.4 gms
100 % correspond to = 223.4 *100/0.324
= 68950.61 gm
MM of haemoglobin = 68950.61 gms = 6.8 E4 gms
Answer:
B) aposematic coloration
Explanation:
The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.
