What is the cell cycle?

Lesson Question
Help please !!!

Answers

Answer 1
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. The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.

All of the following events occur during prophase in mitosis except

WILL MARK BRAINLIEST

A. Condensation of DNA

B. Crossing over

C. Pairing of chromosomes

D. Spindle formation

Answers

The. Answer I believe is c

All of the following events occur during prophase in mitosis except crossing over (Option B)

Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatids condense into chromosomes, thereby making them visible.

The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.

In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.

Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.

In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

what satellites are used to study expanses of the oceans surface

Answers

Answer:

The Geostationary Operational Environmental Satellite-16 (GOES-16) is the first of NOAA's next generation of geostationary weather satellites. Among the many missions of this satellite, it will collect ocean and climate data.

Explanation:

Using satellites, NOAA researchers closely study the ocean. Information gathered by satellites can tell us about ocean bathymetry, sea surface temperature, ocean color, coral reefs, and sea and lake ice. Scientists also use data collection systems on satellites to relay signals from transmitters on the ground to researchers in the field—used in applications such as measuring tidal heights and the migration of whales. Transmitters on satellites also relay position information from emergency beacons to help save lives when people are in distress on boats, airplanes, or in remote areas.

Explain the contribution of antigenic determinant in false negative and false positive test

Answers

Answer:

The contribution of the antigenic determinant is given below:

Explanation:

Antigenic determinant or epitope is the part of the antigen that is recognized by the immune cells or antibodies such as the B- cells by binding to these cells and evokes the response in the host. The antibodies bind to the epitope segments only not to the entire antigen protein.

A false-positive test is a test where the result suggests that an individual has a specific condition but in reality not having such condition. opposite in the false-negative So, the antigenic determinant binds to the specific antibodies and shows wide significance to reduce the false-negative or false-positive.

Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 3 mm from the initial level in 20 min, and when measuring cellular respiration it took 15 minutes for the water level to move down 1 mm.

Answers

Answer:

The rate of photosynthesis is 13 mm/hr

Explanation:

The rate of net photosynthesis is given by;

rate of net photosynthesis = 3 mm / 20 min = 1.5 mm/ 10 min

The rate of  cellular respiration is given by;

rate of cellular respiration = 1 mm / 15 min = 0.667 mm / 10 min

The rate of photosynthesis is given by;

rate of photosynthesis = rate of net photosynthesis + rate of cellular respiration

rate of photosynthesis = 1.5 mm/ 10 min + 0.667 mm / 10 min

rate of photosynthesis =2.167 mm/ 10 min

[tex]rate \ of \ photosynthesis \ in \ mm/hr = \frac{2.167 \ mm}{10 \ min} *\frac{60 \ min}{1 \ hr} = 13 \ mm/hr[/tex]

Therefore, the rate of photosynthesis is 13 mm/hr

Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases?

A. They determine the amino acids in the proteins synthesized.
B. They prevent mutations from occurring in the process of DNA replication
C. They help complete the sugar-phosphate backbone of DNA molecules.
D. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.

Answers

Answer:

A

Explanation:

Essentially, in the process of protein synthesis, there is first transcription where mRNA is synthesized off of a DNA strand with complementary nitrogenous bases. After processing occurs (in basic terms the mRNA is literally processed) and the mRNA strand leaves the nucleus, it attaches to a large and small ribosomal subunit (a ribosome) where translation occurs. The gist of it is when the mRNA strand is being read by the ribosome. tRNA will come over and bind temporarily bringing with it a specific amino acid, starting the formation of the polypeptide/amino acid chain. Nitrogenous bases play into this as the sequence of the nitrogenous bases is what determines what tRNA will bind onto it which determines which amino acid is brought. More specifically, this deals with the codons of the mRNA and the corresponding anticodons with the tRNA, which is a bit of a more specific topic.

The nitrogenous bases help complete the sugar-phosphate backbone of DNA molecules. The correct option is C.

What is DNA?

DNA is composed of chemical key components known as nucleotides. These building blocks are composed of three components: a phosphate group, a sugar group, and one of four different types of nitrogen bases.

Nucleotides are linked together in chains, with the phosphate and sugar groups alternating.
