Do both animal and plant cells have mitochondria? Why or why not?(1 point)
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.
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.

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.

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.

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.

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.

Answer:
All true (sorry if I'm wrong )
Answer:
Question 1: True
Question 2: False
Question 3: True
Explanation:
Question 1: Organism's use and consume energy (work energy) every single day to get through what they need to do.
Question 2: Green plant's using energy from sunlight is refered to as photosynthesis not respiration. Respiration is the need to get rid of carbon dioxide gas aka breathing.
Question 3: Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1. Carbon & sunlight present in the atmosphere is absorbed by plants for photosynthesis.
2. These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3. These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4. Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5. These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
You see the relationship here? So yes, Animals and plants rely on eachother in the process refered to as the carbon cycle.

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.
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.

Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that is toxic in high enough concentrations. It can be a by-product of burning fossil fuels. CO binds irreversibly to the protein (hemoglobin) that transports O2 throughout your bloodstream. As you are exposed to high amounts of CO over a period of time your available hemoglobin becomes unable to bind to O2 because it is bound to CO. In your own words, explain what would happen to cellular respiration and what overall effect this would have on the organism.
Answer:
Carbon monoxide has much more affinity for the hemoglobin than the affinity of the oxygen to the hemoglobin almost 300 times more, which allows the Hb to bind with carbon monoxide irreversibly. Due to this, the small quantity of CO can also reduce the ability of oxygen transport of the hemoglobin.
Longer exposure of CO to the cHb will lead to reducing oxygen release by the Hb that is bound to oxygen in this T state which causes less oxygen availability. In aerobic oxidation mechanisms like oxidative phosphorylation will eventually stop. It will be shifted to anaerobic cellular respiration. The net production of ATP drastically reduced due to anaerobic glycolysis. Cells will eventually start to die causing the death of an organism.
