What role does mutation play in the evolution of a species and the development of new characteristics?

Answers

Answer:

Mutation plays a vital part in evolution; it is the greatest source of genetic variation. In evolution, it creates a new DNA sequence for a particular gene, creating a new allele. Additionally, recombination can produce a DNA sequence (a new allele) for a specific gene through intragenic recombination.

blood type A. The baby they have been given is blood type o. Does the genetic evidence support
their claim?

Answers

No, the claim is not based on scientific evidence because to heterozygous parents with genotype AO may have offspring with O phenotype and therefore OO genotype (proportion 1/4 of descendence).

What is the ABO blood type?

The ABO blood type is a group of phenotypes controlled by a single locus, which is based on the alleles that encode surface antigens in red blood cells. The O phenotype is due to the recessive allele, while the A allele is dominant and therefore masks the O allele in heterozygous individuals.

Therefore, we can conclude that parents having the AO genotype may produce offspring with OO genotype

Describe three different measures that can be obtained from a single age distribution graph comparing males and females of a given population.

Answers

Measurements of height weight and age

A single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.

What is the way to measure the population size ?

The population size can be determined by adding the total number of males and females represented in the graph. This is an important measure of the overall population size, and can be used to compare the population size of different countries or regions.

The age structure of the population can be determined by looking at the distribution of males and females across different age groups. This is an important measure of the demographic makeup of a population, and can be used to identify trends in population growth or decline.

Finally, the gender ratio of the population can be determined by comparing the number of males and females in each age group. This is an important measure of the overall gender balance in a population, and can be used to identify areas where there is a need for greater gender equality.

In conclusion, a single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.

The data table and the cladogram below provide information about the evolutionary history of several different species of animal. Using this information, which of the following is true of trout?

They are more closely related to salamanders than they are to birds.

They are more evolved than salamanders and lizards.
They evolved into a separate species due to the presence of lungs.
They have jaws and lungs but lack claws or nails, feathers, and mammary glands.

Answers

Answer:

They are more closely related to salamanders than they are to birds.

Explanation:

According to the data, trout are more closely related to salamanders than birds.

The first data table shows how the salamander only has one extra trait that the trout does not have (lungs).

On the other hand, birds have three extra traits that the trout doesn't have (claws/nails, feathers, and lungs).

The cladogram further shows how trout are more closely related to salamanders compared to birds.

Trout and the salamander are closer together on the cladogram, while the bird is further away. This means they are more related on the evolutionary timeline.

So, the correct answer is that They are more closely related to salamanders than they are to birds.

The statement which is true about Trout is as follows:

They are more closely related to salamanders than they are to birds.

Thus, the correct option is A.

What is Cladogram?

A Cladogram may be defined as a type of family tree or classification tree which is based on evolutionary relationships. It is also known as a phylogenetic tree.

Trout and the salamander are positioned closer to one another on the cladogram while the bird is being far away. The presence of lungs is marked from the salamander, so trout do not have lungs.

Trouts evolved from Hagfish but not from salamanders and lizards. Trouts only have jaws but lungs, claws or nails, feathers, and mammary glands.

Therefore, the correct option for this question is A.

The process of making food by Green plants (autotroph) is called photosynthesis. For performing photosynthesis water, sunlight and carbon dioxide are used by the plants.

They take sunlight from sun, water from soil and carbon dioxide gas from the air present around us. The leaves have small holes called stomata which allows air to enter the plant. Leaves also contains chlorophyll in them which traps sunlight and helps in making food. Roots of plants absorbs water and Minerals from the soil and transfers them leaves through stem.

Answers

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

Answers

Answer:

B. Osmosis

Explanation:

Osmosis is the process in which oxygen and carbon dioxide exchanged occur between the alveoli and the  capillaries because the oxygen enters the body and the carbondioxide gas leaves the cell through a semi-permeable membrane and we know that Osmosis is a process in which smaller molecules moves from higher concentration to lower concentration through semi-permeable membrane of the cell.

What is Variation?

Variation refers to the variations or deviations from the recognized norm or commonplace. it's going to be a modification in structure, type or operate in associate degree organism, deviating from alternative organisms of identical species or cluster.

In genetic science, variation refers to a personal that possesses characteristics completely different from the others of identical kind. Genetic variation sometimes arises as a mutation sequence that encodes a super molecule or an polymer.

Variations is also mirrored within the composition of the individual, e.g. a distinction in size, color or pattern, or is also detectable solely by deoxyribonucleic acid or super molecule sequencing.

A given variant is also the results of changes during a single sequence, or the consequence of interactions among multiple genes. Populations of identical species living in several components of the globe is also characterized by specific sets of variations.

Variation will, therefore, be measured at the individual level, i.e. variations between individual individuals during a family or population, or at the population level, i.e. variations between populations living in several regions.

The different kinds of variations are:

Environmental factors - Composition variation known as environmental variation.

Inherited factors- The variation passed on from oldsters to offspring, via genes, throughout copy is named heritable variation.

What is Specie?

A species is that the basic unit of classification associate degreed a assortment rank of an organism, furthermore as a unit of variety.

A species is outlined because the largest cluster of organisms within which any 2 people of the suitable sexes or sex activity sorts will turn out fertile offspring, usually by amphimixis.

Other ways in which of shaping species embody

- makeup,

- desoxyribonucleic acid sequence,
