Answer:
Top two images are animal-like and bottom two images are plant-like
Explanation:
<em>Paramecium</em> and <em>Amoeba</em> are animal-like protists. They are unicellular eukaryotes.
Diatoms and brown seaweed are plant-like protists. They are producers of the aquatic ecosystem.
Answer:
monosomy or loss of a single chromosome
Explanation:
- The presence of a given number of chromosomes in a cell that differs from the normal number of chromosomes defined for an organism is termed as aneuploidy.
- There can be either an extra chromosome present or a chromosome that can be missing thus leading to either an increase or decrease in the number of total chromosomes in the organism.
- If there is a loss of a single chromosome in the cell then this type of aneuploidy is termed as monosomy.
- In a normal individual if two copies of one chromosome are present then monosomy would result only in the presence of a single chromosome.
- This type of condition can lead to different genetic defect and disorders , one such example is turner syndrome.
- Therefore, in the spontaneously aborted embryo, the presence of only one chromosome number two is a type of monosomy.
Answer:
B. Early Eukaryotic cells engulfed mitochondria and chloroplasts
Explanation:
Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.
Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.
As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.
