Answer:
First, any soft tissue that was present in life decays, leaving behind the hard parts: bones, teeth, shells. This usually happens very quickly as a result of bacterial action.
Explanation:
Answer:
D) Adenine, Guanine, Cytosine, and Uracil
Explanation:
RNA shares three of the nitrogenous bases of DNA: Adenine, Guanine, and Cytosine. However, instead of thymine, it has Uracil!
Answer/Explanation:
DNA replication doubles each chromosome, meaning the cell can pass on DNA to daughter cells - the duplicated DNA is divided equally between the two new cells formed from the parent.
The laws of inheritance are:
1) The Law of Dominance: An organism with alternate forms of a gene, called alleles, will always display the form that is dominant, masking the recessive trait.
2) The Law of Segregation: In a diploid genome, like most eukaryotes, each trait is defined by a pair of genes (alleles). Each allele is randomly passed on to the gametes so that each gamete only contains one allele. The offspring inherits one allele from each parent during the process of fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted independently from one another That is, the inheritance of one trait does not depend on the inheritance of another trait. so that the inheritance of one trait is not dependent on the inheritance of another.
A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.
<u>Explanation:</u>
With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.
If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.
