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.

Answer:
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.
Which of the following statements best describes the replication of DNA?
a. The double helix unzips the hydrogen bonds between bases and like bases pair up (G with G, C with C, etc.)
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.

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.

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.

B: Different Species that have similar bone patterns
C: Similar species that have body structures with different functions
D:Similar species that have different bone patterns
Answers
Answer:
The answer is Different Species that have similar bone patterns. I am pretty sure.
Explanation:
The biological evolution is evident from different species having similar bone structure. Thus, option B is correct.
The evolution is a process of inheritable changes in the organism over the time. The species develops from the ancestral have similar structures.
What is the evidence of Comparative anatomy?The comparative anatomy is the analysis of the pattern of evolution. The anatomy is dived with organisms belonging to same genus but have different species.
The organism of different species and same genus have similar structure, with the evolution of the functions. Thus, the evolution is evident with the organism of different species with same structure are belonged to same genus.
Hence, the biological evolution is evident from different species having similar bone structure. Thus, option B is correct.
