What is DNA sequence?

Scientists separate strands of DNA from both species using heat, which breaks the bonds between the base pairs that link the two sides of the double helix.

The term "DNA sequencing" refers to a common laboratory procedure for figuring out the precise order of bases, or nucleotides, in a DNA molecule.

The biological information that cells require to develop and function is encoded in the sequence of the bases, which are frequently referred to by the initial letters of their chemical names: A, T, C, and G.

Therefore, Sometimes referred to as DNA-DNA hybridization, this process hybridizes the genetic information from two different organisms to determine similarities between them.

Is this cell haploid or diploid? How can you tell?

Answers

Answer:

The cell shown in the image is haploid, which can be affirmed by the presence of an odd number of chromosomes.

Explanation:

Haploid cells are those that have a single set of chromosomes, that is, half of the chromosomal charge (n) of an organism. These cells correspond to gametes.

Diploid cells are those with complete chromosomal charge (2n) and correspond to somatic cells.

The cell shown in the image is a haploid cell, since it has only three chromosomes. Because diploid cells contain chromosomes in pairs, even if the haploid cell of that species is odd or pair, diploids will always have an pair number of chromosomes.

The Hardy-Weinberg Principal is that genetic frequencies in a population?

Answers

Ans: The Hardy–Weinberg principle states that after one generation of random mating genotype frequencies will be p2, 2pq, and q2. In the absence of other evolutionary forces (such as natural selection), genotype frequencies are expected to remain constant and the population is said to be at Hardy–Weinberg equilibrium.

what does cell cycle mean

Answers

Cell cycle means... A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.

Explanation:

a cell cycle is a series of events that take place in a cell and it grows and it divides a cell speeds most of its time and what is called interface and during this time it grows replicates into chromosomes and prepers for cell division.

here's an example of cell cycle with few exceptions ( for example, red blood cells) all the cells of living things undergo a few cycles the cell cycle is generally divided into two phases interface and mitosis during interface the cell spends most of its time performing the functions that make it unique

and how long does it cycle take usually cells will take between 5 and 6 hours to complete s phase. G2 is shorter lasting only 3 to 4 hours and most cells it's some then interface generally takes between 18 and 20 hours misosis during which the cell makes preparations for the complete cell division only takes about 2 hours

If you have 100 grams of a radioactive isotope (the parent) with a half-life of 10 years, how much of the non-radioactive element (the daughter) will be left after 10 years?

Answers

One half-life after a radioactive isotope is incorporated into a rock there will be only half of the original radioactive parent atoms remaining and an equal number of daughter atoms will have been produced.

The mass of the non-radioactive element (the daughter) that will be left after 10 years will be 25 grams. The correct option is d.

What is a radioactive isotope?

Radioactive isotopes and radionuclides are chemical species of the same elements. Half-life is the time in which half of the radioactive element is reduced. It is the time period of the reduction of the initial half of the radioactive element.

Given the total radioactive element is 100 grams

The age is 20 years

The half-life is 10 years

Hence, the number of half-lives, n=20/10= 2

The formula is

N= (1/2)n No

Where, N = concentration of nonradioactive element

No = Concentration of radioactive element

Put the values in the formula

N= (1 / 2) 2 × 100 = 25 grams

Therefore, the correct option is d, 25 grams.

Photosynthesis, respiration, diffusion, osmosis

respiration, osmosis , diffusion

Chloroplast, respiration, osmosis, diffusion

Answers

Answer:

Photosynthesis, respiration, diffusion, osmosis

Explanation:

Homeostasis refers to the ability of an organism to maintain a stable internal state despite changes in external environment. In order to perform this process, some processes are required to be performed by the cell including:

- Photosynthesis, which is the process by which plants synthesize their food, helps the plant supply energy needed by the cell to perform it's function.

- Cellular respiration is the process of synthesizing energy (ATP) by the cell. Energy is needed by the cell for the numerous functions it carries out. Hence, cellular respiration is a homeostatic process.

- Diffusion is the process by which substance move from a region of high conc. to a region of low conc. until there is even distribution. Without diffusion, some materials cannot get into the cell, hence, it is a homeostatic process.

- Osmosis is the movement of water from a region with high water conc. to a region of low water conc. via a permeable membrane. The osmotic process is also a homeostatic one.
