Scavengers play an important role in the network of food. They keep the world clean from the remains of dead animals, or carrion. Scavengers break down this raw material and recycle it as nutrients into the environment. Vultures consume only the corpses of deceased animals.
Answer:
The correct answer would be - option B. information system.
Explanation:
DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.
So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.
The answer is D all of the above
Carbon is 6
Iridium is 77
Helium is 2
Sulfur is 16 ( not sure)
Hydrogen is 1
So
Hydrogen
Helium
Carbon
Sulfur
Iridium
Sorry if I’m incorrect.
Answer:
D. Aa
Explanation:
Given:
Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa
Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa
Now if both cross and fertilization occurs, we have:
A a
a Aa aa
a Aa aa
The offsprings are (Aa, Aa, aa, aa)
Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.
Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
