Explain why the parents cell and both daughter cells must have the same number of chromosomes
Answers
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.

Animals get their energy by eating plants an animals. A living thing that needs to eat to obtain energy is called a?
Answers
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.

b. The double helix unzips at the phosphate bonds and new nucleotides pair with the appropriate sugars.
c. The double helix unzips the hydrogen bonds between bases and new DNA nucleotides pair with the complementary bases in the old strands.
d. The double helix unzips and RNA forms base pairs with the complimentary strand of DNA.
Answers
Answer:
By hydrogen bonds between nucleotide bases
Explanation:
A DNA molecule is a double-stranded molecule that is informing one structure two strands of nucleotide are involved.
The double-stranded molecule backbone is composed of the phosphate and sugar group and the inside of the backbone are presents the nitrogenous bases. The nitrogenous bases are of four types which are: adenine, cytosine, guanine, and thymine.
These nitrogenous bases are attached according to the Chargaff rule that is adenine binds thymine and cytosine binds guanine. These bases bind with the help of the hydrogen bond as 2 hydrogens participate between adenine and thymine and 3 hydrogens participate between cytosine and guanine.
Thus, hydrogen bonds between nucleotide bases is correct.

Yes; they both need mitochondria to convert radiant energy into chemical energy.
No; plants use chloroplasts the way animals use mitochondria.
No; plants don’t perform any processes for which mitochondria would be used.
Yes; they both need mitochondria for cellular respiration.
Answers
Both animal and plant cells have mitochondria - Yes; they both need mitochondria for cellular respiration.
Cellular respirationIt is a process in which respiratory substrates such as starch, glucose, fats, and proteins are broken down to release energy. This energy is then trapped for the synthesis of ATP to release carbon dioxide.
Cellular respiration takes place in mitochondria, a cell organelle present in all eukaryotic organisms including plants and animals. This organelle is called as powerhouse of the cell as it produces energy for the cell.

Explain why the blue color of starch-iodine complex disappears upon heating?
Answers
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.

type of nutrition shown by all fungi
Answers
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.
