Answer:
The correct answer is "The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs".
Explanation:
One of the fastest way to known if two species have recent common ancestors is to look if they have common taxonomic ranks. In this case we can conclude that The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs, because the coyotes (Canis latrans) and the domestic dogs (Canis familiaris) share the same genus (Canis). The common ancestor of foxes and domestic dogs is more ancient because red foxes (Vulpes fulva) do not share the same genus has domestic dogs (Canis familiaris).
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
The answer is option A.
The Student identifies the test tube
that stops bubbling first contains the catalyst.
Because Catalyst is a substance which
increases the rate of reaction, and the reaction shows that when a product is
obtained bubbles formed.
<span>When the student added X, Y and Z to the
test tubes. The one which is a catalyst fastened the reaction.</span>
