Mitosis maintains chromosomes in each {blank} while meiosis maintains chromosome number in the {blank}.
Answer:
Mitosis maintains chromosomes in each cell division constant, while meiosis maintains chromosome number in half
Explanation:
Mitosis maintains chromosomes in each daughter cell while meiosis maintains chromosome number in the gametes.
What is mitosis and meiosis?Mitosis is the process by which a cell divides into two identical daughter cells, each with the same number and type of chromosomes as the parent cell. During mitosis, the cell's DNA is replicated, and the replicated chromosomes are evenly distributed into the two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes, maintaining chromosome number in the daughter cells.
Meiosis, on the other hand, is the process by which a cell divides into four non-identical daughter cells, known as gametes. During meiosis, the cell's DNA is replicated, and the replicated chromosomes are shuffled through a process called crossing over. This shuffling results in gametes with unique combinations of chromosomes, which helps to maintain chromosome number in the gametes. Gametes, also known as sex cells, are the cells involved in sexual reproduction, and they are important for maintaining chromosome number in offspring.

Which letter in Figure 1 represents meiosis? Why?
Which letter in Figure 1 represents mitosis? Why?
The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.
Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).
Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.
Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

During fertilization, each haploid ____________ contains the entire genetic contribution from one of the two parents.
Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to have formed from these prokaryotes. How does the endosymbiotic theory explain the development of the first eukaryotic organisms?.
The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells. The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

The properties of water are the result of multiple factors including; polarity and hydrogen bonding. Which property of water is not a result of polarity?
A.Water dissolves salts and sugars.
B.Water will become less dense when frozen.
C.Water is transparent and lets sunlight pass through.
D.Water will from a spherical bead due to surface tension
Water is transparent and lets sunlight pass through. Therefore, the correct option is C.
Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.
Therefore, the correct option is C.
