Humans have undergone evolutionary transitions, as mammals like whale resembled other mammals in terms of skulls and other sculptures on the basis of the fossils found.

The program begins with one of the most popular examples of a purported change used by the evolution contingency: the transition from land animals to the whale. This shift is demonstrated to be explained by the fossils of Pakicetus, Ambulocetus, Rhodocetus, Dorontid, and Basilosaurus. In contrast to a complete transitional fossil, Pakicetus only has a small piece of its cranium to show for itself. Although Ambulocetus is depicted in the documentary as a fully preserved fossil of an aquatic mammal with legs, this is an embellishment and stretching of the truth given that the skeleton of the animal was actually found to be very fractured. In the series, Rhodocetus is only depicted by a skull.

Many people have asserted that those "legs" weren't just vestigial; they also participated in copulation. They might have even had a swimming feature. In conclusion, two skulls, one incomplete, maybe transitional skeleton, and a complete aquatic whale type with short hind legs. Our top example of an apparent evolutionary transition comes from these data.

In the beginning of "The World on Turtle's Back," we can see that a character named just as "husband" is terrified of being punished for having destroyed the sacred tree that lit up the world where he lived.

"The World on Turtle's Back," is a myth created by the Iroquois to explain the origin of the earth and living things. In this myth, we can see:

There was a realm above the heavens that was created even before the earth was created.

This realm was inhabited by magical beings who did not die, grow old, or get sick. They were called the people of heaven.

There was a tree in the center of that realm that was holy.

The tree lit up the entire kingdom, since the sun did not exist.

One day, one of the women of the heavenly realm discovered that she was pregnant with twins. She is very happy and tells her husband, but he is furious with the news, to the point of pulling the sacred tree from the ground. This causes a hole and he throws his pregnant wife into that hole.

The man is terrified, not because he threw his wife to an unknown end, but because he destroyed the sacred tree and is afraid of being punished.

Despite the fall, the woman survives and gives birth to the twins who will create all the elements of planet earth.

With this, we can conclude that the Iroquois also created myths to explain things they did not know, such as the origin of the planet and human beings.

DNA polymerase enzyme proofreads the DNA molecule to minimize errors during DNA replication.

DNA polymerase enzymes are the enzyme that carries out DNA replication. During this mechanism, a wide range of errors can occur. DNA polymerase read the nucleotide in the template strand and pairs it with the complimentary nucleotide, that is adenine to thymine and guanine to cytosine. But errors occur all the time during this pairing.

But DNA polymerase also carries out proofreading along with the formation of the strand. When an incorrect nucleotide is paired, the whole mechanism is arrested. DNA polymerase identifies the errors by detecting the variation in the 3' OH group. The strand formation is stopped, and the incorrect nucleotide is replaced by the correct one, only after that the process continues.

The errors during DNA replication are rectified either by Base excision repair or Nucleotide excision repair. These are carried out by DNA polymerase as well as DNA ligase enzymes

DNA replication and proofreading are undertaken by the same enzyme, DNA polymerase.

Technically, both are correct, but I would go with Jahiem.

Explanation:

In terms of how orange trees are normally produced, they usually reproduce asexually, but farmers will graft parts of trees to create new ones. But, normaly trees reproduce sexually.

Write down: An orange tree in the wild is not genetically similar to the one next to it

I agree with Phoebe that orange trees will be genetically identical to each other.

I think these trees reproduce rely on mitosis as there are no seeds to plant. So I predict that all orange trees will be genetically identical to each other and to their parents.

In reproduction, the plant does not need another gamete to reproduce. For this type of reproduction, parts of the plant are removed to obtain new plants, which is known as a clone. Therefore, what is really used in this type of reproduction is the genetic material of the plant.

Whit this information, we can conclude that i agree with Phoebe that orange trees will be genetically identical to each other.

(This definition I got from the web so credits to them)

A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

Answer:

precipitation and temperature

Explanation:

Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.

Sucrose will not yield a positive Fehling's test

A reducing sugar, or a sugar that can reduce copper ions, is detected using the ideal Fehling's test. Fehling's solution, which consists of copper(II) sulphate and a strong base, is mixed with a sugar solution to be tested, and the mixture is then heated.

During this process, the copper ions will be reduced to copper(I) oxide if a reducing sugar is available, and this copper(I) oxide will then react with the strong base to generate a precipitate of copper(I) hydroxide, which will change its color to red. A positive Fehling test result would be produced by reducing sugars like lactose, maltose, and other disaccharides, but not by non-reducing carbohydrates like sucrose.

The critical value the scientist should use for the chi-square analysis of the data is b. 3.84.

The chi-square test is a statistical test used to determine whether there is a significant difference between the observed and expected frequencies in a contingency table. In this case, the scientist is investigating whether two traits in a plant, long stems and white flowers, are determined by genes that are on the same chromosome. The scientist has conducted a genetic cross between plants that are homozygous dominant and homozygous recessive for both traits, and has obtained a sample of 100 plants in the F2 generation. The scientist has then tabulated the observed and expected frequencies of the four possible phenotypes (long stems, white flowers; short stems, red flowers; long stems, red flowers; short stems, white flowers) in the F2 generation.

The chi-square test is used to determine whether there is a significant difference between the observed and expected frequencies in the table. The calculated chi-square value is compared to a critical value from a chi-square distribution table with 3 degrees of freedom and a significance level of 0.05. The degrees of freedom for a chi-square test are equal to the number of categories in the table minus 1. In this case, there are 4 categories (phenotypes) in the table, so the degrees of freedom are 3.

The critical value for this test is 3.84. If the calculated chi-square value is less than 3.84, the scientist would conclude that there is no significant difference between the observed and expected frequencies and thus the genes independently assort, meaning that the genes are located on different chromosomes. On the other hand, if the calculated chi-square value is greater than 3.84, the scientist would conclude that there is a significant difference between the observed and expected frequencies and thus the genes are located on the same chromosome.

The primary source of water for wetlands is from precipitation, such as rain.

This water of precipitation is absorbed by the soil and saturates the ground, eventually making its way into the wetland.

Other sources include groundwater, water runoff from rivers, streams, and lakes, and even direct connections to larger bodies of water. In some cases, wetlands are purposefully flooded to create a habitat.

The water level in a wetland is regulated by a variety of factors, including the size of the wetland, the amount of water that flows in, the amount of water that evaporates, and the amount of water that is absorbed by plants.

In addition, wetlands can be impacted by human activities, such as dam and reservoir construction and over-irrigation, which can lead to an increase or decrease in the water level.
