The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.
<u>Asexual Reproduction:</u>
This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.
- The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
- Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
- Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.
<u>Sexual Reproduction:</u>
- A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
- That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
- These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.
Answer: C polluted water and soil can cause many deseases and side effect towards humans
Answer:
1) Founder effect and genetic drift: Small colonizing population did not represent the original gene pool of the source population and was more likely to undergo genetic drift.
2) Natural selection
Explanation:
Evolution of the population of the finches with larger beaks might have occurred due to one of the following mechanisms:
a) Founder effect and genetic drift: Since the size of the colonizing population was small, it did not carry all the genes and their alleles present in the gene pool of the original population. The small population size made it more likely to evolve by any chance event.
b) Natural selection: The availability of different food types in the new habitat led to the natural selection of the larger beaks as the finches with larger beaks might have been able to better exploit the available food resources.
A stored form of carbohydrate in animals' muscle and liver is glycogen.
Glycogen is a polysaccharide (starch) made of repeating units of glucoses bonded together.
Answer:
Bacteria
Explanation:
Bacteria have no true nucleus because it's a prokaryote. It couldn't have been a virus because all naturally occurring viruses are pathogenic unless treated by radiation.
We have two types of bacteria,
- Pathogenic
- Commensals
Pathogenic bacteria will definitely cause disease. Commensals, however, have don't harm us and have the ability to help us.
Eg: Flora (bacteria) in our intestines produce vitamin K and most of the vitamin B complex. They also compete with the pathogenic bacteria that you might've ingested and don't allow them to increase to the number that can cause disease.
