In order for a cell to successfully complete a cycle, the process must occur as the duplicated chromosomes are aligned, separated, and transferred to the cell's poles opposite during the multi-step process known as the mitotic phase. Following this, the cell division occurs into two brand-new, identical daughter cells.

The M phase is a term used to describe the process of mitosis or cell division. Here, the cell divides to create two new, identical daughter cells using previously replicated DNA and cytoplasm. The four basic phases of mitosis are prophase, metaphase, anaphase, and telophase. A cell must grow, replicate its DNA, and physically separate into two daughter cells before it can divide. These actions are carried out by cells in a cell cycle, an ordered and predictable succession of processes.

The cell cycle is a cycle as opposed to a linear pathway because, at the conclusion of each cycle, the two daughter cells can restart the entire process from scratch. The cell cycle is divided into two main phases eukaryotic cells, or cells containing a nucleus: the interphase and the mitotic (M) phase.

Hemoglobin is the protein found in red blood cells that transports oxygen throughout the circulatory system.

The red blood cells (erythrocytes) of almost all vertebrates, with the exception of the fish family Channichthyidae, and some invertebrate tissues, contain hemoglobin, an iron-containing oxygen-transport metalloprotein.

The blood's hemoglobin transports oxygen from the respiratory system, including the lungs and gills, to the rest of the body (i.e. tissues). There, oxygen is released, allowing aerobic respiration to take place and produce energy for an organism's metabolic processes.

Other gases are also transported by hemoglobin, which carries some of the body's respiratory carbon dioxide (20–25% of the total)as carbaminohemoglobin, a form of hemoglobin in which carbon dioxide is bonded to the heme protein.

Genotype B is NOT possible for the given parent genotypes.

This genotype resembles one parent's genotype. It is based on the supposition that gamete fusion and chromosomal nondisjunction did not take place. In sexual reproduction, the child receives half of its chromosomes from each parent, hence the offspring cannot have the same genotype as one parent. This explains why, throughout the meiotic process of creating gametes, the number of chromosomes is cut in half.

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.

Approximately, Vmax = 0.001996,Km=6. It is an enzyme that is known to follow michaelis- menten kinetics. Michaelis–Menten kinetics is one of the best-known models of enzyme kinetics.

Michaelis-Menten kinetics is one of the most well-known models of enzyme kinetics in biochemistry. The German biochemist Leonor Michaelis and the Canadian doctor Maud Menten are honored by its names. Michaelis-Menten kinetics, which was first developed as a mathematical model of enzyme reaction rates, is commonly used to explain how nutrients like oxygen are absorbed by cultured cells

The model depicts a cell (cell c) building a complex with a substrate (substrate s), consuming the substrate, and then producing a product (product p). More nutrients can then be taken in by the cell and enzyme

Slope=Km/Rmax

Km=slope/intercept=6/0.002 = 3000

Slope=(0.015-0.005)/(0.75-0.25)=6

The difference between the tropics in the Northern Hemisphere and the Southern Hemisphere is the rotation.

Explanation:

Tropical storms in the Northern Hemisphere rotate clockwise, while those in the Southern Hemisphere rotate counterclockwise.

The reason is something called the Coriolis effect, or Coriolis force, named for the French mathematician Gaspard-Gustave de Coriolis, who published work on the effect in the 19th century. Like a record on a turntable, the earth spins at a different speed at the equator than it does at the North Pole.

The same is true of anything that spins or rotates — the outside edge of something (in this case, the equator) always spins faster than the inside edge.

Answer: Plants colour their fruits to flag down the right animals

Explanation: Why are raspberries red and bananas yellow?

 A scientific debate has raged for decades about whether plants evolve to produce fruits of particular colours to attract particular animals to help spread their seeds. A new study appears to have finally settled it.

Researchers looked at similar plants in two similar mountain rainforests in Uganda and Madagascar and found that the palette of fruit colours in the two forests is tuned to the way the local fruit-eating animals see the world.

Hungry black bears drawn to residential areas in search of fruit trees, berries

In Uganda, most fruits ripen to a bright red — standing out against the green leaves when spotted by the birds and the local monkeys, which have colour vision similar to ours.

In Madagascar, where the mostly nocturnal lemurs can't tell the difference between red and green, the ripe fruits tend to be green — but shades of green that contrast brightly against the leaves when viewed with "lemur vision," the study, published in the journal Biology Letters, found.

Plants talking to animals

Plants typically signal to the animals when the fruit is ripe by changing its colour — something scientists consider to be a form of communication.

So it might seem obvious that plants would evolve and produce fruit of the right colour to attract the right animals to eat them.

 But scientists have found proving this theory isn't so easy, and many previous studies show no evidence of that kind of evolution.

Plus, there are other possible explanations for why fruits are the colours they are. Perhaps it's just genetic, and therefore all related plants in that lineage have the same colour. Or maybe it's because the plant happens to make pigments of that colour for other plant parts.
