Scientists are examining the possible role of a large asteroid in the Cretaceous mass extinction event. A large asteroid strike
QveST [7]

Answer:

Option C

Explanation:

The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.

Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)

And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"

Hence, option C is correct

Garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. What happens to the other mem
Alex17521 [72]

The correct answer is (d) The number of plants and birds increases and the number of snail decreases.

Green plants are eaten by snails, snails by birds, and birds by household cat. If cat is removed from the cycle then the number of birds will increase which will decrease the number of snail in the environment.  As there are large number of birds there will be a great demand of snails as a food for birds. Then there will be a decrease in the number of snails because of over eating of snails. There will be an increase in the number of garden plants because very less number of snails are left that will eat garden plants.

What is  mitochondrial genomes?

The DNA found in mitochondria, which are cellular organelles found in eukaryotic cells that transform chemical energy from food into a form that cells can utilise, such as adenosine triphosphate, is known as mitochondrial DNA (mtDNA or mDNA)](ATP). Only a small amount of the DNA in a eukaryotic cell is contained in the mitochondria; the majority of the DNA is found in the cell nucleus and, in plants and algae, also in plastids like chloroplasts.

The first large portion of the human genome to be sequenced was mitochondrial DNA.

According to this sequencing, the human mtDNA contains 16,569 base pairs and codes for 13 proteins.

Animal mtDNA serves as a cornerstone of phylogenetics and evolutionary biology because it evolves more quickly than nuclear genetic markers .
