Explanation:

The man's AB blood will dominate over the recessive O blood of the mother.  The possible outcomes shown by a Punnett Square are A and B children.

Answer:

Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. ... These separated sister chromatids are known from this point forward as daughter chromosomes.

Answer:

receptores olfativos especializados localizados en el epitelio olfatorio de la mucosa nasal

Explanation:

Las neuronas receptoras del olor se denominan receptores olfatorios. Los receptores olfatorios son células especializadas capaces de percibir miles de sustancias químicas diferentes y decodificar la información en miles de olores distintos. Estos receptores se localizan en la mucosa nasal de las fosas nasales. En el caso del olor a rosa, como así también cualquier otro olor, las sustancias químicas responsables del olor se dirigen al epitelio olfatorio de la mucosa nasal, donde se unen a receptores específicos localizados sobre filamentos sensoriales (cilios) en las membranas celulares de las neuronas especializadas. La unión desencadena una respuesta en la células neuronales, es decir, una descarga eléctrica que se propaga desde las fosas nasales hasta el cerebro, el cual decodifica la información (el olor) en una región conocida como bulbo olfatorio.

Explanation:

The diploid chromosome number for a radish is 18 and the diploid chromosome number for cabbage is also 18. The haploid number for these species is nine. Therefore, the gametes of the radish and cabbage contain nine chromosomes.

Answer: Translation

Explanation:

During the transcription the double stranded DNA act as a separate template  strand to produce mRNA molecule. The mRNA molecule encode for amino acid chain that collectively forms the protein. The ribosomes are the sites of protein synthesis the mRNA get attached to the ribosome. Within the ribosome the rRNA molecule instruct the catalytic steps for the synthesis of protein. The amino acid sequence or chain gets stitched together to form the protein.

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

Answer:

D. they do not have stems, roots and leaves

Algae are not considered as plants as they do not have roots, stems, and leaves.

They are a group of predominantly photosynthetic, aquatic, and nucleus containing organisms, which are devoid of the following things:

Algae comprises chloroplasts and generate food by the process of photosynthesis. However, they are not considered as plants, as they are devoid of several other compositions of true plants like roots, leaves, or stems.

Thus, the correct answer is option D.

Answer:

[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]

Explanation:

Let the frequency ,

[tex]f = L^{x}T^{y}m^{z}[/tex]

Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.

So,

[tex]T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\[/tex]

collecting the like bases, we have

[tex]T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ][/tex]

Equating powers on both sides, we have

x + y - z = 0  (1)

y + z = 0       (2)

-2y = -1         (3)

From (3), y = 1/2

From (2), z = -y = -1/2

Substituting y and z into (1), we have

x + y - z = 0

x + 1/2 - (-1/2) = 0

x + 1/2 + 1/2 = 0

x + 1 = 0

x = -1

So,

[tex]f = L^{x}T^{y}m^{z}\\f = L^{-1}T^{\frac{1}{2} }m^{\frac{-1}{2} }[/tex]

[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]

Explanation:

1. His symptoms consist of difficulty walking and an abnormal gait (pattern of movement such as walking, running, etc)

2. a. one purpose of the blood test was to test his creatine kinase enzyme to see if there were any medical conditions connected to the way he was walking and why it was abnormal

b. the other purpose is to be sure that he has something wrong with his gait. If he does have a medical condition, it was best to see if he had it early on to treat it faster

3. the function of dystrophin gene connects to the cytoskeleton of a fiber which has to do with brain function; we need that to walk. For DMD, that is a condition that alters the way people walk.

4. DMD is inherited from family's genes, so he got it from his birth family probably from his dad's part of the family as DMD effects men more than women

5. It is pretty likely as this medical condition is inheritably passed on. It is likely that his grandchild will get DMD

6. To treat DMD to the best of the ability since there isnt a cure, they could participate in physical therapy and steroids

Answer:

there are two main methods used to find the amino acid sequences of proteins. Mass spectrometry is the most common method in use today because of its ease of use. Edman degradation using a protein sequenator is the second method, which is most useful if the N-terminus of a protein needs to be characterized.

Explanation:

Answer and Explanation:

The transport and digestion of proteins is done by other proteins called enzymes. An example of this occurs in the biochemical digestion of proteins, where the enzyme pepsin promotes digestion, the breakdown of proteins into smaller pieces, through hydrolysis which is the breakdown of molecules with the use of water. These pieces of the protein are transported to the duodenum where they are digested again by the enzyme enterokinase.
