it would be C because kingdom is animalia, phylum is chordata, class is mammalia and order is carnivora and humans and tigers are both carnivors
The correct answer is B. Oxygen.
Oxygen, as a part of the atmosphere, also participates in UV protection, besides being necessary for breathing.
The correct answer is letter A, the increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.
This is one of the many chain reactions that agricultural farming brings to the environment, and it will be very common through the years as people have not figured out a safer way to protect crops.
Prophase- *Nuclear membrane
disappears
( so chromosomes can
move around)
Metaphase- Chromosomes
line up in the middle of the cell
Anaphase-*Chromosome copies
pull apart from each other.
Telophase-<span>*Nuclear division
has finished and nuclear membrane reappears</span>
<span> This is the process for Meiosis 1 not for 2 (FYI)</span>
Answer:
A. much of the variation in individuals of a population is heritable
Explanation:
Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.
Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
