If the DNA sequences of two species are identical, this would indicate that they share a common ancestor. So, the correct option is B.
What is Ancestry?An ancestor is also called forefather, fore-elder, or a forebear. It is defined as the parent of the parent or predecessor. An ancestor is any person from whom one is descended living in law, a person from whom property is inherited.
Ancestry links genetics and society in fundamental ways, while it has cultural, religious or political significance, and can play an important role in shaping personal and public identity.
Homologous can occur when different species have similar anatomy that is shared due to ancestry or shared due to similar selective pressures.
Thus, if the DNA sequences of two species are identical, this would indicate that they share a common ancestor. So, the correct option is B.

Explain why Calix's cells having more DNA than a normal cat meant point mutation was not the cause.
Mutation is the reason for the more DNA in Calix's cells.
Calix's cells having more DNA than a normal cat because of the mutation in the genes. There is no other way through which DNA in a gene increases. This increase in DNA from a normal condition leads to cancer and other disorders.
Mutation occurs in an organism when they are exposed to radiation which damaged the DNA of that organism so we can conclude that mutation is the reason for the more DNA in Calix's cells.

Which of the following is a positive way that palm oil farms provide humans with natural resources.
Palm oil is found in all types of food and biofuels.
Palm oil produces more oil for a similar amount of land than other plants.
Palm oil tastes better and is healthier than other types of oils.
Palm oil has no positives related to natural resources.
Answer:
The palm oil industry has helped lift millions of people out of poverty in Indonesia and Malaysia, which together account for around 85 per cent of global production. Oil palm plantations have created millions of well-paying jobs, and enabled tens of thousands of smallholder farmers to own their own land.
Explanation:
Hope it helps.
Brainliest plz!!!!!!!!!!!! Plz, plz, plz, plz!!!!!!!
Answer:
Option -2 Palm oil produces more quantity of oil for a similar amount of land than any other plant is the correct answer.
Explanation:
firstly,
what is palm oil?Edible vegetable oil that is gathered from the mesocarp i.e., the reddish pulp of the fruit of the oil palms is known as palm oil. The oil is used in food manufacturing, making beauty products, and as biofuel.
Palm oil has many advantages that are listed below-
Palm oil is used for preventing aging, cancer, and brain disease and reduces heart disease risk.Oil palm plantation has provided millions of paying jobs and enabled thousands of smallholder farmers to own their land. Palm oil has a long shelf-life and is solid at room temperature, making it an ideal ingredient in a variety of food.Palm oil is used to manufacture sodium lauryl sulfate, which is widely used as a foaming agent(soap) in many body care products for e.g.-soap, detergents, etc.Besides all these positive ways one of the important uses of palm oil farms is that it helps in conserving natural resources.
How do palm oil farms help in conserving natural resources?
Oil palms are significantly more efficient than any other oil-producing crops. A single hectare of land can produce about 4.17 metric tons of sunflower oil, 0.16 tons of ground oil, and 0.39 tons of soybean oil. this means that significantly less land has to clear to meet demands for vegetable oil while other crops require at least five times more land to produce the same volume of oil as oil palms.
Conclusion-Palm oil produces more oil per land area than any other equivalent vegetable oil crops.
hence, the second option that says a similar amount of land produces more oil in the case of palm oil is the correct answer.

One end of the rope is vibrated to produce a wave with a wavelength of 0.25 m. The
Frequency of the wave is 3.0 Hz. What is the speed of the wave? *
1)3.00m/s
2)2.50m/s
3)0.75m/s
4)1.25m/s
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.

One of the four fundamental interactions in nature is? Electromagnetism Gravity Strong interaction All of the above
Answer:
The correct answer is All of the above. In nature there are four forces, (also called interactions or fields in Physics) that are responsible for all phenomena in the universe: the gravitational force or interaction, the strong interaction, the electromagnetic and the weak nuclear.
Explanation:
The fundamental interactions or forces that describe all the interactions between the constituents of matter are each of the interactions that matter can undergo and that cannot be decomposed into more basic interactions. There are four basic forces that describe all interactions: Gravitational, that is responsible for the interaction between particles with mass and, by extension, for the configuration on a macroscopic scale of the Universe and its stability. Electromagnetic, is responsible for the interaction between electrically charged particles and, by extension, for all Chemical reactions, Weak is responsible for the disintegration of certain unstable particles; that is, of those processes in which some particles decompose (decay) into lighter ones and Strong interaction is the most complicated interaction to describe due to its different behaviors at different action distances; by means of which a global vision of the to physics without breaking it down.
19. Explain the following observation made by Gregory Mendel in his experiments, A cross between a
pure breed tall plant and a pure breed dwarf plant had all the first filial generation being tall.
Answer:
The correct answer is - can be explained by the law of dominance.
Explanation:
In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.
It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.

How does the number of genes in human cells compare with the numbers in other species?
Answer:
While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always proportional to genome size (blue bars, in millions of base pairs). Note how many genes a fruit fly can squeeze out of its relatively small genome.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.Comparative genomics also provides a powerful tool for studying evolutionary changes among organisms, helping to identify genes that are conserved or common among species, as well as genes that give each organism its unique characteristics.While the number of genes in an organism's DNA varies from species to species, it is not always proportional to genome size.Learn more:
