In case anyone googled this and it comes up, its ecosystem.
B. The cell contains a nucleus.
C. The cell uses ribosomes to create protein.
D. The cell contains DNA
The crucial feature that proves a cell is eukaryotic is the presence of a nucleus, as this is the fundamental characteristic that differentiates eukaryotic cells from prokaryotic ones.
In biology, the quintessential feature that distinguishes eukaryotic cells from prokaryotic cells is the presence of a nucleus. So, we can conclude that the observation which proves that a cell is a eukaryote is B. The cell contains a nucleus. Eukaryotic cells are equipped with a true nucleus, which houses the cell's DNA. Other features such as a cell membrane, ribosomes, or the existence of DNA could be attributed to both eukaryotic and prokaryotic cells, hence they are not unique identifiers for eukaryotes.

D. Octupled (x8)
The answer is B.
Explanation:
Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).
However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
The germ cell, or diploid cell, duplicates its DNA to create haploid cells (gametes) with one set of chromosomes each. This process of duplication is part of meiosis, ensuring that offspring receives the correct number of chromosomes from each parent.
The germ cell, a type of diploid cell, contains two sets of chromosomes. Each gamete, typically described as haploid cells, needs to have one set of chromosomes. To have enough DNA for each gamete, the DNA in the germ cell must be duplicated, which is a part of the process of meiosis.
This process of meiosis helps reduce the number of chromosome sets in each cell so that when two gametes (like a sperm cell and an egg cell) combine during fertilization, they can create a new diploid cell with two sets of chromosomes - one from each parent. If meiosis didn't occur, the resulting cells would have too many chromosomes, which is not sustainable for life.
Most animals and plants are diploid, meaning they have two sets of chromosomes in their body cells or somatic cells. However, gametes, the reproductive cells, are haploid and carry just one set. This ensures that upon fertilization, the embryo will have the correct number of chromosomes.

The eustachian tube help a frog survive they are used to equalize pressure within the internal ear whilst the frog is swimming. A slender tube that connects the tympanic hollow space with the nasal part of the pharynx and serves to equalize air strain on both aspects of the eardrum. The Eustachian tube helps the frog to bring in sound and to listen. The Eustachian tube of a frog equalizes the strain of the internal ear by using beginning and final, which aids with sound and listening. They help to stabilize the frog. The Eustachian tubes additionally cause the eardrums. Or as a substitute so it's simpler to consider the most important function of the frog's Eustachian tube is that it became especially used for equalizing stress inside the internal ear while the frog is swimming. It equalizes the pressure of the frog's inner ear even as it is swimming. Used to equalize strain inside the internal ear while the frog is swimming. It gives blood to Equalize stress between the inside and outside ear.
Valsalva maneuver, Pinch your nostrils closed with your arms. try to preserve your cheeks neutral or pulled in as opposed to puffing out. next, blow air gently thru your nostrils. This generates stress inside the back of the nostril, which may additionally assist open the eustachian tube.
A commonplace direction of remedy for Eustachian tube dysfunction is using decongestants or antihistamines. In some instances, this treatment may additionally make the situation worse. If decongestants or antihistamines no longer provide a remedy, touch your medical doctor. you could want to peer an ear, nostril, and throat specialist for treatment.
Hypersensitive reactions and infections (like the common bloodless and the flu) are the maximum common reasons for eustachian tube dysfunction. Those conditions can cause infection and mucus buildup, leading to blockage. GERD, or continual acid reflux disorder, also can be purpose ETD.

They are used to equalize pressure in the inner ear while the frog is swimming. A slender tube that connects the tympanic cavity with the nasal part of the pharynx and serves to equalize air pressure on either side of the eardrum. The Eustachian tube helps the frog to bring in sound and to hear. The Eustachian tube of a frog equalizes the pressure of the inner ear by opening and closing, which aids with sound and hearing. They help to balance the frog. The Eustachian tubes also lead to the eardrums.
