The following statements are true for the production of Angelman syndrome:

2. Children of affected females have a 50% chance.

3. Meiotic nondisjunction of a normal paternal chromosome 15 accompanied by loss of a normal maternal chromosome 15

6. Deletion of the maternal gene copy

The mutated or missing maternal copy of a portion of chromosome 15 causes Angelman syndrome. Most of the time, it is because of the gene UBE3A, which is on chromosome 15 at the 15q11 to 15q13 locus. It encodes the ubiquitin protein, which is necessary for the electron transport chain and various functions of the cell membrane.

In most cases, this father-inherited gene is deactivated in the cortex, thalamus, and hippocampus of the brain. In these regions, the only source of genetic information for ubiquitin synthesis is the maternal gene. Therefore, neurological symptoms result from any mutation or deletion of this gene or a portion of chromosome 15 in the maternal gamete. The offspring are unaffected by mutations in the paternal gamete.

a) The mass of the oxygen is 1.97 g

b) The percent yield is 90.4 %

c) The mass of the oxygen is 1.55 g

We know that the percent yield has to do with the amount of the reactants that has been converted into products in the given reaction. In this case, the reaction that we are dealing with is the decomposition of the potassium oxo chlorate V molecule.

Now we have that;

a) Number of moles of the chlorate = 5 g/122.5 g/mol

= 0.041 moles

If 2 moles of the chlorate produces 3 moles of the oxygen

0.041 moles of the chlorate produces 3 moles * 0.041 moles/ 2 moles

= 0.0615 moles

Mass of the oxygen produced = 0.0615 moles * 32 g/mol

= 1.97 g

b) Percent yield = Actual/Theoretical * 100/1

=  1.78/1.97 * 100/1

= 90.4 %

c) For a percent yield of 78.5% =

Actual = Percent yield * Theoretical /100

= 78.5 * 1.97/100

= 1.55 g

% yield = (1.78 g / theoretical yield) × 100%

To calculate the percent yield, you need to know the actual yield and the theoretical yield of the reaction.

In this case, the actual yield is given as 1.78 g of O₂. The theoretical yield represents the maximum amount of product that can be obtained under ideal conditions.

To calculate the theoretical yield, you need to know the balanced chemical equation for the reaction. Assuming the reaction is complete, the coefficients of the balanced equation can be used to determine the stoichiometry of the reaction.

For example, if the balanced equation is:

2 A + 3 B → 4 C + 2 D

Then, you can use the stoichiometry to find the theoretical yield. Let's say the molar mass of O₂ is 32 g/mol. In this case, we need to calculate the moles of O₂ using the given mass of 1.78 g:

moles of O₂ = mass of O₂ / molar mass of O₂

Next, we need to use the stoichiometry to find the moles of the desired product. Let's assume that O₂ is the limiting reactant and that it is completely converted to the product. From the balanced equation, we can see that 4 moles of C are produced for every 2 moles of O₂:

moles of C = moles of O₂ × (4 moles of C / 2 moles of O₂)

Now that we have the moles of C, we can calculate the theoretical yield of C in grams by multiplying the moles by the molar mass of C.

theoretical yield of C = moles of C × molar mass of C

Finally, we can calculate the percent yield using the formula:

% yield = (actual yield / theoretical yield) × 100%

Substituting the values we calculated:

% yield = (1.78 g / theoretical yield) × 100%

Please note that without the balanced chemical equation and additional information, it is not possible to provide a specific numerical answer for the percent yield.

The statement which provides evidence about the decreased rate of cell division is B)Decreased affinity of growth factor receptors for their respective ligands. So, correct option is B.

In each of the 4 tissues, there was a critical decline in cell division rates with age. Conversely, cell division rates didn't diminish in that frame of mind of matured mice, and just little abatements were seen in their small digestive tract or throat. These outcomes have significant ramifications for grasping the connection between ordinary undeveloped cells, maturing, and disease. Besides, they give a conceivable clarification to the baffling age-subordinate deceleration in disease frequency in exceptionally old people however not in mice.

Another assessment of recently distributed information recommended to us that the amassing of changes could slow, as opposed to increment, as people age. To make sense of this surprising finding, we estimated that ordinary undifferentiated cell division rates could diminish as we age. To test this speculation, we assessed cell division rates in the epithelium of human colonic, duodenal, esophageal, and back ethmoid sinonasal tissues.

The restriction enzymes when combined with the DNA containing restriction sites lead to cuts at those sites yielding restriction fragments. The second statement is correct.

The restriction enzymes are the enzymes that recognize specific sites known as restriction sites. These are enzymes that are found in bacteria and this feature is used as a modern biotechnology tool for genetic editing.

There are two ways the ends are formed after the action of a restriction enzyme. It can form blunt ends or sticky ends. The sticky ends have a region at the end that is single-stranded. This region can then join according to the complementary base pairing with another strand having complementary sticky ends.  

If it is assumed that the RE (restriction) enzyme is not interrupted during the generation of restriction fragments, the resulting restriction fragments would not yield more restriction fragments when re-incubated with the RE enzyme.

Basidiospore, Basidium, Ascus are the structures that are part of the sexual life cycle of Basidiomycota.

Basidiomycota are a group of fungi that reproduce sexually through a process called basidiomycetous reproduction. In this process, the fungi produce special reproductive structures called basidia, which are located on the surface of the fruiting body (also known as the basidiocarp). The basidia contain special cells called basidiospores, which are released when the basidia mature and burst. The basidiospores are then carried away by wind or other means and can germinate to form new fungal cells. The process of basidiomycetous reproduction also involves the formation of asci, which are special cells that contain ascospores. These ascospores are produced through meiosis and can give rise to new fungal cells when they germinate. The structures listed above that are NOT part of the sexual life cycle of Basidiomycota include conidia, conidiospores, zygospores, and rhizopus sporangium, which are all involved in asexual reproduction.

This can help the group to avoid danger and increase their chances of survival. While giving a warning call may put the individual squirrel at risk, the benefits of warning the rest of the group can outweigh this cost. Additionally, some research has suggested that animals that give warning calls are less likely to be targeted by predators, as the calls can alert the predator to the presence of the group and make it more difficult for the predator to catch any individual member of the group. Overall, giving warning calls can be an effective strategy for increasing the survival chances of the group as a whole.

If you are referring to what happens if the mass of an atom is greater compared to an atomic number, we can say that there is nothing too much, since it is normal for the atoms to have a mass slightly greater than the atomic number. The mass of an atom can never be less than the number of protons added to the number of neutrons. An atom with greater mass has a greater number of electrons and neutrons in relation to an atom of less mass and it is likely that the atom of less mass will donate or share electron with the atom of greater mass so that both reach the electric balance.
