Division of cells resulting in the development of an embryo from a zygote happens after fertilization. Therefore, option "A" is correct.
What is fertilisation?The creation of a single cell known as a zygote by the fusion of a female gamete is egg and a male gamete a sperm. The biological process of fertilization in animals entails the union of a sperm as the male gamete and an egg as the female gamete or ovum.
The three techniques of internal fertilization are oviparity is an egg deposited outside of the female body, oviparity is an egg kept within the female, and viviparity is said to be developed within the female followed by live delivery.
Therefore, fertilization is the first step in the development of the zygote and the development of life.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population
Explanation:
Why anti-poaching?Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.
In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.
It is therefore our call to stop the slaughter of rhinos with all our might.

A dominant trait is the name of the trait that hides or masks another genetic trait.
What do you mean by dominant trait?Dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
The dominant trait is the one that is the first to appear or express itself visibly in the organism. Example: In human beings, we observe V-shaped hairline.
Dominant individuals are often most influential in their social groups, affecting movement, opinion, and performance across species and contexts.

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.

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.

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.

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.
