Put "Evolution of Populations" in a sentence

Explanation:

the answer is C cardiac muscle I'm pretty sure this is the correct answer

An example of reproductive isolation is two populations of salamanders that live in different lakes. Thus, the correct option is C.

Reproductive isolation may be defined as the inability of a species to interbreed successfully with related species members due to isolating mechanisms.

Reproductive isolation may leads to speciation. A single specie scan generates multiple species via reproductive isolation. The members of the same species undergo reproductive isolation due to several isolating mechanisms.

The isolating mechanisms include geographical, behavioral, physiological, or genetic barriers.

Therefore, the correct option for this question is C.

Mitosis gives two nuclei, and hence two cells while meiosis gives four.

Mitosis gives identical cells to each other and to the mother cell while meiosis leads to genetic variation due to crossing over and independent assortment.

Mitosis includes one division while meiosis includes two.

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

Identify important checkpoints in cell division

Explain how errors in cell division are related to cancer

The length of the cell cycle is highly variable, even within the cells of a single organism. In humans, the frequency of cell turnover ranges from a few hours in early embryonic development, to an average of two to five days for epithelial cells, and to an entire human lifetime spent in G0 by specialized cells, such as cortical neurons or cardiac muscle cells. There is also variation in the time that a cell spends in each phase of the cell cycle. When fast-dividing mammalian cells are grown in culture (outside the body under optimal growing conditions), the length of the cycle is about 24 hours. In rapidly dividing human cells with a 24-hour cell cycle, the G1 phase lasts approximately nine hours, the S phase lasts 10 hours, the G2 phase lasts about four and one-half hours, and the M phase lasts approximately one-half hour. In early embryos of fruit flies, the cell cycle is completed in about eight minutes. The timing of events in the cell cycle is controlled by mechanisms that are both internal and external to the cell.

Explanation:

Regulation of the Cell Cycle by External Events

Both the initiation and inhibition of cell division are triggered by events external to the cell when it is about to begin the replication process. An event may be as simple as the death of a nearby cell or as sweeping as the release of growth-promoting hormones, such as human growth hormone (HGH). A lack of HGH can inhibit cell division, resulting in dwarfism, whereas too much HGH can result in gigantism. Crowding of cells can also inhibit cell division. Another factor that can initiate cell division is the size of the cell; as a cell grows, it becomes inefficient due to its decreasing surface-to-volume ratio. The solution to this problem is to divide.

Whatever the source of the message, the cell receives the signal, and a series of events within the cell allows it to proceed into interphase. Moving forward from this initiation point, every parameter required during each cell cycle phase must be met or the cycle cannot progress.

Regulation at Internal Checkpoints

It is essential that the daughter cells produced be exact duplicates of the parent cell. Mistakes in the duplication or distribution of the chromosomes lead to mutations that may be passed forward to every new cell produced from an abnormal cell. To prevent a compromised cell from continuing to divide, there are internal control mechanisms that operate at three main cell cycle checkpoints. A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. These checkpoints occur near the end of G1, at the G2/M transition, and during metaphase

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.  

Ants belongs to Formicide family  which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.

The diversity of ants is every where except Antarctica.

The body has three parts such as  a head, a meso-some and metasoma or gaster.

Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.

The reproduction in which young, queens  fly during mating time, fertilize with male, this flight is called as nuptial flight.

Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.

Thus, option D is correct.
