What if a mutation occurred in the human insulin gene and the first triplet was changed to C C G? Is this a silent mutation?
Yes, this will be a silent mutation.
Explanation: The mutation which occurred in the human insulin gene where the first codon was changed to CCG will be a silent codon because this will not change the sequence of the amino acid and the amino acids formed will remain the same.

In 1935, cane toads were first introduced to Australia from Hawaii as a biocontrol agent. The toads were meant to replace the use of toxic pesticides to reduce the native cane beetle population that was decimating sugar cane, a valuable Australian crop. Since their release, however, cane toads have rapidly multiplied: over 70 years, the population increased from 100 individuals to over 200 million! The toads have devastated local ecosystems, including spreading diseases to native wildlife, preying on native fauna, and out-competing native insectivores for food. Additionally, no evidence has been found that they have had any effect on the cane beetles that they were meant to control. What type of growth model does the cane toad population follow?
Answer:
Exponential growth model
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population.
Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate is dense-dependent. Eventually, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The cane toad is an invasive omnivore species, feeding on anything, going from other animal species to invertebrates and vegetables. In urban areas, they might even feed on dogs food or human food wastes. The species characterizes by its high adaptative capability to different environments, the significant reproductive rate -leaving abundant offspring-, and the toxins produced in the parotids. For these traits, it has become a severe invasive species. Their poison is dangerous and painful, causing irritation of the skin and mucose, and many times, causing blindness. Predators get in contact with this toxin and get poisoned to death. Many native predators have suffered a reduction in their population size due to the effects of the Bufo toad. Also, as they prey on many other species, they eventually affect the ecosystemic equilibrium, driving many native species to extinction.
According to the description of the species and the information provided, we can assume that the population is going through exponential growth. Resources seem to be abundant enough, their reproductive rate is very high, and they are good competitors to native species. In 70 years, its population increased from 100 individuals to 200 million and still growing. It does not seem to be any limiting factor (or not yet at least), nor space nor food or shelter affecting the development. Unless there is something that might limit it, the species will keep showing exponential growth.
What is Fermentation ?
Answer:
Fermentation is an enzyme catalysed, metabolic process whereby organisms convert starch or sugar to alcohol or an acid anaerobically releasing energy. The science of fermentation is called “zymology”. Fermentation is an anaerobic biochemical process

What was the discovery scientists made in the 1950's that led them to then accept Wegener's theory of Continental Drift?
Answer & explanation:
The theory of continental drift emerged a long time ago. When mapping some points on Earth, scholars suspected that the continents were united in the past.
Francis Bacon suggested in 1620 that the east coast of the South American continent and the west coast of Africa fit together perfectly, giving the impression that they had parted in the remote past. A similar observation to this had already been made by another scholar named Abraham Ortelius, around 1596.
A century later, hypotheses became a scientific theory with previously elaborated arguments. Then, the theory of Continental Drift was officially born, when the German Alfred Wegener formulated it in 1912, establishing that the Earth had been divided, in its slow fragmentation, into two great continents, Laurasia and Gondwana.

This pedigree shows the inheritance Leber congenital amaurosis (LCA) which is a type of hereditary blindness. Individuals with this disease lose their vision during childhood. 3. What is the inheritance pattern shown?
About the question: You will find the pedigree in the attached files
Answer:
Autosomal recessive inheritance
Explanation:
Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
Let us assume that the diallelic autosomal gene has a dominant allele L that expresses the normal phenotype and the recessive allele l that expresses the altered phenotype. The pedigree would be as shown in the attached files.
To interpret the pedigree, remember that
Squares represent malesCircles represent femalesEmpty figures express normal/healthy/not affected individualsSolid black figures represent affected individualsLeber congenital amaurosis (LCA) is a type of Autosomal recessive inheritance. Individual with this disease loses their vision during childhood.
What is Pedigree Analysis?The study of the inheritance of genetic traits in several generations of a human family in the form of a family tree diagram is called Pedigree analysis.
Two copies of these alleles are required to express the recessive phenotype and are responsible for the inheritance of LCA. As autosomal recessive inheritance expresses its trait when both the alleles of each parent are in recessive form and the resulted offspring shows the inheritance pattern.
Hence, LCA is an autosomal recessive inheritance caused by the expression of both recessive alleles simultaneously in an individual.

1. How do you get your zenith distance from the altitude of the Sun at solar noon?
2. How do you get your latitude from your zenith distance and the Sun's declination?
Answer: The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
Since it is South of the Zenith, we add the zenith distance to the declination to find our latitude: our latitude = the declination + the zenith distance = -17° + 39° = +22° (North latitude).
