Explain why the parents cell and both daughter cells must have the same number of chromosomes
Answer:
It's occur in mitosis.
Explanation:
This occur mainly in Mitosis.
In mitosis the parent cell divides into two daughter cells and its then replicates it chromosomes number or dna in the daughter cells. Therefore each daughter cells carries the same number of chromosome as the parent , therefore they are genetically identical as the parent cells.
Therefore, they most have the same number of chromosomes so that they can be genetically identical as the parent cell
Daughter mitotic cells must have the same genetic information as parent cells to carry out normal cellular functions. Moreover, mitosis also ensures the correct segregation of homologous chromosomes in successive cell divisions.
Mitosis is a type of cell division in which one cell divides to produce two daughter cells that are genetically identical to the parental cell. This type of division occurs in all types of cells in the body, with the exception of gametic cells located in the ovary (egg) and the testicles(spermatic cells). In diploid (2n) cells that have two sets of homologous chromosomes, mitosis results in the formation of two 2n cells with identical genetic content.Thus, mitosis ensures that the number of chromosomes in each cell division is constant, thereby daughter cells will have the same number of chromosomes as the parent cell. This maintenance of the chromosome number is fundamental to grow and self-maintain the body.Chromosome imbalance due to errors during mitosis (i.e., error in segregation of homologous chromosomes) may lead to the disruption of large numbers of dosage-sensitive, developmentally essential genes and therefore result in disease/lethal phenotypes.Conversely, meiosis is a reductional type of cell division that reduces the number of chromosomes in the parent cell by half in order to four gamete haploid (n) cells. During fertilization, male and female n gametes fuse to produce a diploid cell (i.e., the zygote) that develops into an adult, thereby perpetuating the correct number of pairs of chromosomes in the cells of any given species.

List the Earth’s 4 spheres and give 1 example from your Environment for 2 of the speres.
Answer:

Earth's Spheres
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air). Each of these four spheres can be further divided into sub-spheres. To keep things simple in this course, there will be no distinction among the sub-spheres of any of the four major spheres.
Lithosphere - Land
The lithosphere contains all of the cold, hard solid land of the planet's crust (surface), the semi-solid land underneath the crust, and the liquid land near the center of the planet.* The surface of the lithosphere is very uneven (see image on right). There are high mountain ranges like the Rockies and Andes (shown in red), huge plains or flat areas like those in Texas, Iowa, and Brazil (shown in green), and deep valleys along the ocean floor (shown in blue).
The solid, semi-solid, and liquid land of the lithosphere form layers that are physically and chemically different. If someone were to cut through Earth to its center, these layers would be revealed like the layers of an onion (see right image above). The outermost layer of the lithosphere consists of loose soil rich in nutrients, oxygen, and silicon. Beneath that layer lies a very thin, solid crust of oxygen and silicon. Next is a thick, semi-solid mantle of oxygen, silicon, iron, and magnesium. Below that is a liquid outer core of nickel and iron. At the center of Earth is a solid inner core of nickel and iron.
* Note: The word "lithosphere" can take on different meanings depending on the speaker and the audience. For example, many geologists--scientists who study the geologic formations of Earth--reserve the word "lithosphere" to mean only the cold, hard surface of Earth, not the entire inside of the planet. For the purpose of this course, however, there will be no distinction among the various layers of land. The word "lithosphere" will be used in reference to all land in Earth's system.
Hydrosphere - Water
The hydrosphere contains all the solid, liquid, and gaseous water of the planet.** It ranges from 10 to 20 kilometers in thickness. The hydrosphere extends from Earth's surface downward several kilometers into the lithosphere and upward about 12 kilometers into the atmosphere.
A small portion of the water in the hydrosphere is fresh (non-salty). This water flows as precipitation from the atmosphere down to Earth's surface, as rivers and streams along Earth's surface, and as groundwater beneath Earth's surface. Most of Earth's fresh water, however, is frozen.
Ninety-seven percent of Earth's water is salty. The salty water collects in deep valleys along Earth's surface. These large collections of salty water are referred to as oceans. The image above depicts the different temperatures one would find on oceans' surfaces. Water near the poles is very cold (shown in dark purple), while water near the equator is very warm (shown in light blue). The differences in temperature cause water to change physical states. Extremely low temperatures like those found at the poles cause water to freeze into a solid such as a polar icecap, a glacier, or an iceberg. Extremely high temperatures like those found at the equator cause water to evaporate into a gas.
** Note: Some scientists place frozen water--glaciers, icecaps, and icebergs--in its own sphere called the "cryosphere." For the purpose of this course, however, frozen water will be included as part of the hydrosphere. The word "hydrosphere" will be used in reference to all water in Earth's system.
Biosphere - Living Things
The biosphere contains all the planet's living things. This sphere includes all of the microorganisms, plants, and animals of Earth.***
Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Deserts, grasslands, and tropical rainforests are three of the many types of biomes that exist within the biosphere.

type of nutrition shown by all fungi
Fungi cannot produce their own food like plants can, nor can they consume it like animals can. Instead, fungi get their nutrition by absorbing it from their surroundings.
What is fungi ?Eukaryotic creatures known as fungi include yeasts, molds, and mushrooms as well as other microbes. These organisms fall under the category of fungus. The creatures that make up the Kingdom Fungi are pervasive and have a cell wall. They fall under the category of heterotrophs among living things.
Both varieties of fungi emit digestive enzymes into the nutrient surface they are growing on in order to feed. Proteins and carbohydrates are broken down by the enzymes and then absorbed through the walls of the hyphae.
All fungi are heterotrophic, which means they draw their energy from other living things. Like animals, fungi draw energy from live or dead organisms through the bonds of organic substances like sugar and protein.
Thus, Fungi cannot produce their own food like plants can, nor can they consume it like animals can.

Explain why the blue color of starch-iodine complex disappears upon heating?
Answer: Starch is a long polymer molecule in one shape of a coil. The iodine molecules goes inside of the coil and this is what makes it turn blue/black. Iodine is a diatomic element with the formula, I2.
Explanation:
Answer:
This is because the compound of iodine and starch is unstable, but if you put the test tube in cold water, a dark blue sediment will form once more. When starch is heated to boiling point, it begins to break down, and the chains of amyloses break, thus, forming short chains of dextrins, so the colour starts to change.

Animals get their energy by eating plants an animal. A living thing that needs to eat to obtain energy is called a heterotroph.
Energy is defined as the property of matter that allows it to perform work or function.
Heterotrophs are organisms that obtain their energy by consuming other living things, such as plants or animals. They play an important role in the food chain, as they consume other living things and transfer energy up the chain.
For example: A herbivore (an animal that eats plants) is a heterotroph that obtains energy from the plants it consumes.
Therefore, heterotroph is a living thing that needs to eat to obtain energy.

assume that life on Mars requires cell potential to be 100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na : 145; K : 4; Cl- : 120. Choose one species and assume that other two probabilities are zero. Design the cell by calculating the intracellular concentration of the chosen species.
Answer:
Explanation:
From the information given:
The cell potential on mars E = + 100 mV
By using Goldman's equation:
[tex]E_m = \dfrac{RT}{zF}In \Big (\dfrac{P_K[K^+]_{out}+P_{Na}[Na^+]_{out}+P_{Cl}[Cl^-]_{out} }{P_K[K^+]_{in}+P_{Na}[Na^+]_{in}+ P_{Cl}[Cl^-]_{in}} \Big )[/tex]
Let's take a look at the impermeable cell with respect to two species;
and the two species be Na⁺ and Cl⁻
[tex]E_m = \dfrac{RT}{zF} In \dfrac{[K^+]_{out}}{[K^+]_{in}}[/tex]
where;
z = ionic charge on the species = + 1
F = faraday constant
∴
[tex]100 \times 10^{-3} = \Big (\dfrac{8.314 \times 298}{1\times 96485} \Big) \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]100 \times 10^{-3} = 0.0257 \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]3.981= \mathtt{In} \Big ( \dfrac{4}{[K^+]_{in}} \Big)[/tex]
[tex]exp ( 3.981) = \dfrac{4}{[K^+]_{in}} \\ \\ 53.57 = \dfrac{4}{[K^+]_{in}}[/tex]
[tex][K^+]_{in} = \dfrac{4}{53.57}[/tex]
[tex][K^+]_{in} = 0.0476[/tex]
For [Cl⁻]:
[tex]100 \times 10^{-3} = -0.0257 \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)[/tex]
[tex]-3.981 = \ \mathtt{In} \Big ( \dfrac{120}{[Cl^-]_{in}} \Big)[/tex]
[tex]0.01867 = \dfrac{120}{[Cl^-]_{in}}[/tex]
[tex][Cl^-]_{in} = \dfrac{120}{0.01867}[/tex]
[tex][Cl^-]_{in} =6427.4[/tex]
For [Na⁺]:
[tex]100 \times 10^{-3} = 0.0257 \Big ( \dfrac{145}{[Na^+]_{in}} \Big)[/tex]
[tex]53.57= \Big ( \dfrac{145}{[Na^+]_{in}} \Big)[/tex]
[tex][Na^+]_{in}= 2.70[/tex]

The correct answer is - raising in water becomes puffed, or uptake of water and minerals from roots.
Explanation:
The minimum pressure applied to a solution to prevent the entering the flow of its pure solvent through q semipermeable membrane. The process of flowing the pure solvent to the solution through a semipermeable pressure is known as osmosis and the minimum pressure required to preventing the osmosis is osmotic pressure.
Many plants springing up through tree roots growing through concrete. Due to osmotic pressure, the plants grow they require more water, the inexorable osmotic pressure of water moves through the membranes can actually push through asphalt!
Movement of salt-water in the animal cell across our cell membrane and keep raisin in water and the raisin gets puffed are other examples of this phenomenon.
