Write the nuclear equation describing the synthesis of mendelevium-256 by the bombardment of einsteinium-253 by a particles. On the reactant side, give the target nuclide, on the product side, give the synthesized nuclide.

Answers

Answer 1

On the reactant side, the target nuclide is einsteinium-253 (^25392Es), and on the product side, the synthesized nuclide is mendelevium-256 (^256100Md).

How can mendelevium-256 be synthesized?

The synthesis of mendelevium-256 by the bombardment of einsteinium-253 by alpha particles can be represented by the following nuclear equation:

^25392Es + ^42He → ^256100Md

The synthesis of mendelevium-256 by the bombardment of einsteinium-253 by alpha particles is a nuclear reaction in which an alpha particle, which is a helium-4 nucleus (^42He), is fired at the target nucleus of einsteinium-253 (^25392Es). This reaction is an example of a type of nuclear reaction known as nuclear fusion, in which two atomic nuclei combine to form a heavier nucleus.

During the reaction, the alpha particle collides with the nucleus of einsteinium-253, which has a mass number of 253 and an atomic number of 92, and the two particles combine to form the nucleus of mendelevium-256 (^256100Md). Mendelevium-256 has a mass number of 256 and an atomic number of 100, indicating that it has 100 protons in its nucleus, making it an element with atomic number 100.

The nuclear equation that represents this reaction is balanced in terms of both mass and charge, as the sum of the mass numbers and the sum of the atomic numbers are the same on both sides of the equation. This is a fundamental requirement in nuclear reactions, as the total number of protons and neutrons, as well as the total electric charge, must be conserved during the reaction.

Answer:

LEARNING OBJECTIVES

Identify important checkpoints in cell division

Explain how errors in cell division are related to cancer

The length of the cell cycle is highly variable, even within the cells of a single organism. In humans, the frequency of cell turnover ranges from a few hours in early embryonic development, to an average of two to five days for epithelial cells, and to an entire human lifetime spent in G0 by specialized cells, such as cortical neurons or cardiac muscle cells. There is also variation in the time that a cell spends in each phase of the cell cycle. When fast-dividing mammalian cells are grown in culture (outside the body under optimal growing conditions), the length of the cycle is about 24 hours. In rapidly dividing human cells with a 24-hour cell cycle, the G1 phase lasts approximately nine hours, the S phase lasts 10 hours, the G2 phase lasts about four and one-half hours, and the M phase lasts approximately one-half hour. In early embryos of fruit flies, the cell cycle is completed in about eight minutes. The timing of events in the cell cycle is controlled by mechanisms that are both internal and external to the cell.

Explanation:

Regulation of the Cell Cycle by External Events

Both the initiation and inhibition of cell division are triggered by events external to the cell when it is about to begin the replication process. An event may be as simple as the death of a nearby cell or as sweeping as the release of growth-promoting hormones, such as human growth hormone (HGH). A lack of HGH can inhibit cell division, resulting in dwarfism, whereas too much HGH can result in gigantism. Crowding of cells can also inhibit cell division. Another factor that can initiate cell division is the size of the cell; as a cell grows, it becomes inefficient due to its decreasing surface-to-volume ratio. The solution to this problem is to divide.

Whatever the source of the message, the cell receives the signal, and a series of events within the cell allows it to proceed into interphase. Moving forward from this initiation point, every parameter required during each cell cycle phase must be met or the cycle cannot progress.

Regulation at Internal Checkpoints

It is essential that the daughter cells produced be exact duplicates of the parent cell. Mistakes in the duplication or distribution of the chromosomes lead to mutations that may be passed forward to every new cell produced from an abnormal cell. To prevent a compromised cell from continuing to divide, there are internal control mechanisms that operate at three main cell cycle checkpoints. A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. These checkpoints occur near the end of G1, at the G2/M transition, and during metaphase

How did scientists begin to Mark divisions in the geologic time scale in response to a change they discovered in the geologic record

Answers

Answer:

Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.

Explanation:

Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.

They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.

An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.

As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.

This range of events became known as the geological time scale.

The age of fossils and rocks is also used to map out the calibrations on the scale.

The age of fossils and rocks is determined using the process of radioactive dating.

With respect to normal base pairing, when a molecule of DNA replicates, thymine will most likely pair with 2 points

Answers

Answer: Adenine

Explanation:

The structure of the DNA double helix is complex in nature. There are two strands of DNA that are wound around each other. The nitrogenous bases are bonded with hydrogen bonding and base complementarity. According to the Chargaff's rule of base complementarity adenine always pairs with the thymine and guanine with cytosine. These nitrogenous bases are paired on the basis of hydrogen bonding. Adenine bonded with thymine through two hydrogen bonds whereas the cytosine pairs with guanine via three hydrogen bonds. During DNA denaturation these hydrogen bonds are broken whereas during DNA replication these hydrogen bonds are formed between the nitrogenous bases.
