Answer:
<u>Option-</u> "Proteins and Nucleic acid."
- In animals, nitrogenous wastes are produced mostly from the catabolism(break down of macro molecules into simpler ones) of <u>Protein molecules. </u>
Explanation:
- <u> Proteins and nucleic acids:</u>
Most of the organisms ingest different types of materials. And some of them are proteins which are composed up of different amino acids, as the proteins are important in many ways, they help in cells reproduction and growth etc.
And the nucleic acids are important polymers, which are required for carrying the operation of genetic material from one cell or being to another.Or it may occur simply from one generation to another in the form of RNA and DNA.
<u>Why they are broken down?</u>
Both the polymers consists the Nitrogen atom as the main constituent in there molecular structure, so that is why the break down of these materials results in the form of nitrogenous materials.
- When proteins level exceeds from a certain level they need to be controlled and thus required the excessive materials to be excreted from the body. There are different forms or levels of the nitrogenous waste products which are excreted from an animal body. As there levels of organisms excrete them in different forms,which are as below:
- <u>Beings living on land and Marine Fish:</u> The nitrogenous waste is excreted mostly in the form of urea or uric acid, but mostly in the urea which is just because they have an optimum level of water as the solvent.Along with that the marine fish can also excretes the nitrogenous waste in the form of trimethylamine oxide.
- <u>Ave's(Birds):</u>Birds have a less availability of water in there body which makes them to excrete the nitrogenous waste product in the form of uric acids.
- <u>Freshwater Fish:</u> They excrete the amount of nitrogenous waste from the body in form of ammonia, as they have an abundance of water as solvent. While, there is an abundance of water in the environment, which they are able to dissolve the amount of nitrogenous waste products present inside the body and excrete it in the form of ammonia. Which is less toxic form of the nitrogenous waste materials.
Answer:
Nitrogen is the right answer.
A diploid cell is a cell that contains two sets of chromosomes. Each
chromosome pair is considered to be one set of homologous
chromosomes. ... Gametes are haploid cells . During sexual
reproduction, gametes (sperm and egg cells ) fuse at fertilization to
form a diploid zygote.
Answer:
the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.
Explanation:
Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.
This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.
Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
