Answer:

Answer:

The correct answer is - 38.15 gm of NaCl.

Explanation:

Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):

2Na + Cl₂ —> 2NaCl

the mass of Na and the mass of NaCl :

Molar mass of Na = 23 g/mol

In the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

similarly in balanced equation = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

By converting it to 15 grams of Na.

Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.

Thus, 38.15 g of Na

Explanation:

Leukemia

A type of cancer which affects the production and function of blood cells. This causes swollen lymph nodes, recurrent nosebleeds, tiredness, frequent infections, weight loss, bleeding, and bone pain. Leukemia symptoms vary, depending on the type of leukemia. Common signs and symptoms of leukemia include:

Swollen lymph nodes especially in the neck and armpits

Experience pain in bones

Night sweats - excessive sweating, especially at Night

Weakness and fatigue

Rapid weight loss

Red spots on the skin

Bleeding and bruising easily

Fever or chills

Frequent infections

Causes

The exact cause is not known. Hereditary and environmental factors may play a role in developing the disease.

The risk factors include:

Mutations in the DNA are frequently a major cause.

Sometimes chromosome translocation can also promote activation of oncogenes (the cancer inducing genes) and this can lead to disease progression.

Exposure to certain chemicals and radiation can also induce cancer.

Answer:

Chromosome pairs with its corresponding homologous chromosome to form a tetrad.

The question is kind of confusing but from what I understand; missense mutations happen when an amino acid is changed to another amino acid. To find out more specifically, look at a codon chart trust me it helps so much lol (just search codon chart and go to images). missense mutations can also cause a premature stop codon so look for a changed amino acid and a stop codon when u look at the codon chart. maybe if u see the different pairs you can get a more specific answer. I hope this helps :)

Answer:

Carbohydrate (monosaccharide)

Explanation:

Carbohydrates are one of the four biological molecules in nature. Carbohydrates are structurally composed of carbon, hydrogen and oxygen elements. However, these elements (C,H,O) are present in each carbohydrate in the ratio 1:2:1 respectively.

As stated in this question, glucose is an organic molecule made up of carbon, hydrogen and oxygen in the 1:2:1 proportion, hence, it is a CARBOHYDRATE. Since glucose possess one sugar component, it is classified as a MONOSACCHARIDE with a chemical formula C6H12O6.

The basic unit of the chemical elements

Answer:

The correct answer is: automaticity.

Explanation:

Cardiac muscle has several properties. These properties are: automaticity (given by the pacemaker cells), conductivity (meaning that each cardiac cell can transmit the electrical impulse to the next cardiac cells), contractility (like other types of muscles, cardiac muscle cells can contract), and irritability (each cell can contract on its own without the external stimuli).

Cardiac pacemaker cells are the ones with the capacity to initiate the electrical impulse by creating rhythmic impulses called action potentials, and thus directly regulating heart rate.

Pacemaker cells are located in the sinoatrial (SA) node, in the upper portion of the right atrial wall. In these cells, depolarization of the cardiac muscle begins, and the electrical impulse generated by it is transmitted to the atrioventricular (AV) node, the His bundle and then the Purkinje fibers - this order of events is necessary for the correct contraction of the heart to occur. All of these structures are part of the Conduction System of the heart.

Explanation:

Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:

1/3200 = q² (have two CFTR mutant alleles) >>  

q = √ (1/3200) = 1/56.57 >>

- Frequency of the CFTR allele q = 1/56.57 = 0.0177  

- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823

Answer:

Sexual reproduction is able to generate genetic variation in offspring by 1-independent assortment and 2-recombination during meiosis, and 3-random fertilization.

Explanation:

Sexual reproduction is a type of reproduction that increases the amount of genetic variation in offspring by three main mechanisms: independent assortment of homologous chromosome pairs and recombination during meiosis, and random union of gametes during fertilization. First, sexual reproduction is associated with the independent assortment of chromosomes during meiosis, i.e., the orientation of homologous chromosome pairs is a random process that is different for every cell that undergoes meiosis. In consequence, chromosomes assort randomly into gametes, thereby the segregation of alleles of a gene pair is independent of the segregation of another set of alleles of a different gene (as stated in the law of independent assortment). Second, sexual reproduction generates genetic variation by recombination, which is the exchange of genetic material between non-sister chromatids during meiosis I (prophase I). This genetic process (recombination) is able to generate new alleles in offspring. Third, sexual reproduction also involves the random union of two haploids (n) gametes during fertilization, which results in the formation of a diploid (2n) zygote that develops into a new individual. In humans, the sperm cell has 8 million possible (2²³) chromosome combinations, which fertilizes an ovum cell that also has approximately 8 million chromosome combinations, thereby producing a tremendous genetic variation in offspring (around 64 trillion possible zygote combinations).

Solution :

It is given that a woman is a nonsecretor but the father of that woman is a secretor. It means that the father's genotype is recessive, i.e. "ss".

The genotype of the nonsecretor mother would be Ss, who have received one recessive allele from her father.

Now the nonsecretor man have a secretor daughter from his previous marriage. That means that he is a carrier nd his genotype is Ss.

Now, we can cross between the heterozygous parents (Ss x Ss) will have offspring with the following genotypes :

1 SS -- Nonsecretor

2 Ss -- Nonsecretor

1 ss -- secretor

Thus the probability that their first child will be :

a). a secretor girl

   [tex]$=\frac{1}{4} \times \frac{1}{2}$[/tex]

  [tex]$=\frac{1}{8}$[/tex]

b). Non secretor girl

     [tex]$=\frac{3}{4} \times \frac{1}{2}$[/tex]

     [tex]$=\frac{3}{8}$[/tex]

c). a secretor boy

   [tex]$=\frac{1}{4} \times \frac{1}{2}$[/tex]

   [tex]$=\frac{1}{8}$[/tex]

Answer:

here's your answer

Explanation:

the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.

Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

The Doppler Effect talks about the frequency of sound and light as the source and person move. So, When light waves are emitted by a moving source, scientists can measure = the Doppler effect.

Cosmic microwave background radiation has the word "cosmic" in it, so you can assume it has to do with space automatically. There is radiation in space too, so I'm pretty sure that The extremely low temperature of outer space can be explained as = cosmic microwave background radiation.

Particle accelerators are these big machines that usually smash protons/electrons together, so Scientists smash together tiny bits of matter using = particle accelerators.

And now, by process of elimination and because the Big Bang Theory talks about the creation of Earth, we know that Scientists extrapolate backwards in time to derive = the Big Bang Theory.

Answer:

Agreeableness.

Explanation:

Agreeableness is the trait that narcissists likely to have which is negatively corelated and is associated with leader emergence but not effectiveness. The tendency toward self-interest would attract the person into follow his or her own goals rather than the interests of their group or company. The term Narcissism originated from Greek mythology, where a young man whose name is Narcissus fell in love with his own image reflected in a pool of water so that's why selfness and self interests refers to Narcissism.
