Explanation:
when dogs breed the mother and father each randomly contribute one allele from each locus giving each allele 50% chance of being passed down to the pups. one of the alleles at each locus is dominant and determines the traits like coat color
Answer:
approximately 860 light-years (260 pc) from Earth
In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.
<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>
Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.
The following components could be found in a normal prokaryotic cell:
- The membrane enclosing and guarding the cell is known as the cell wall.
- All of the cell's internal components, excluding the nucleus, are called cytoplasm.
- Some prokaryotic cells have filaments made of proteins called flagella and pili.
- A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
- A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>
Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

<u>Answer:</u>
Fossils are the sources to learn the changes on the earth and how much it changed in these years. Its provides us with information about the existence of plant and animals in the past.
Actually, the fossils we found till the date are the ancestors of the plants and animals that live today. Moreover, some fossils of animals are easily identifiable since they exist till the date.
But there are fossils of animals that exist no longer in the earth. By studying and analyzing the fossils, one can tell how life on the earth has changed.
Also, we can learn about the ancestors of the plants and animals and how their long life existed on earth.
In other words, one can learn where and how those organisms were lived. So that we can know about our ancient environments.
Answer:
The five kingdom classification are- Monera, Protista, Fungi, Plantae and Animalia. The organisms which are placed under the kingdom Animalia are heterotrophic and depend on the other organisms for food. ... These are multicellular organisms which are composed of many cells and can perform activities like locomotion.
