Answer:

VII. Anaphase II

Explanation:

During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach <u>Anaphase II</u><u>,</u> during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole

nexus9112 [7]

The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.

<u>Asexual Reproduction:</u>

This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.

  • The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
  • Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
  • Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.

<u>Sexual Reproduction:</u>

  • A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
  • That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
  • These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.

1. What organisms undergo cellular respiration?
emmasim [6.3K]
1. Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
2. Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell's main energy-carrying molecule.
3. Some cells have more mitochondria than others because they need to process more glucose and produce more ATP.
4. The inner membrane folds over many times and creates layered structures called cristae.
5. In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas.
6. Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

What product do all three reactions in Model 2 have in common?
belka [17]

Answer;

-They all provide water

Explanation;

In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.

In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.

-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.

Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.

What first spurred research into what has now become green building?
Ghella [55]
San Francisco has an opportunity to reap tremendous economic, environmental, and health benefits by adopting recent advances in “green building”—benefits that will only increase in value over time. Many standard building design, construction, operation, and renovation practices are outmoded, inefficient, costly, and have adverse health and economic effects. The shift to new, environmentally sensitive practices would maintain San Francisco’s status as a leader in urban planning and environmental innovation. A shift to green buildings is also vital to enhancing San Francisco’s livability for its residents, workers, and visitors.

Can clindamycin be used for patient with liver disease
Pie
We administered 300 mg of clindamycin intravenously at 12-h intervals for 2 days to patients with acute and chronic hepatitis, cirrhosis, and controls to determine whether clindamycin will exacerbate preexisting hepatic dysfunction or whether drug excretion will be delayed in patients with liver disease
