Answer:

The colors you see in flowers come from the DNA of a plant. Genes in a plant's DNA direct cells to produce pigments of various colors. When a flower is red, for instance, it means that the cells in the petals have produced a pigment that absorbs all colors of light but red.

Explanation:

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Answer:

I. Constante de resorte, k = 150 Nm.

II. Fuerza = 67.5 Newton.

Explanation:

Dados los siguientes datos;

Fuerza, F = 30 N

Extensión, e = 0.2 m

Para encontrar la constante del resorte;

Fuerza = constante de resorte * extensión

F = ke

30 = k * 0.2

Constante de resorte, k = 30 / 0.2

Constante de resorte, k = 150 Nm

A continuación, para encontrar la fuerza para una extensión de 0,45 m;

Fuerza = 150 * 0.45

Fuerza = 67.5 Newton.

Answer:

Endangered

Explanation:

Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.

Hence, if a marine biologist writes an article about saving whales and labels them as endangered species, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem.  Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable.

Central diagram

Explanation:

Answer: I believe it is Thigmotropism.

This is thigmotropism as it is responding to touch. Since the plant cannot support itself, it wraps around the lattice structure.

Answer: C

Explanation: At that point, you have all of the momentum from B, and it is RIGHT at that point before it starts to lose energy. It has all of the built up momentum that started at A, and continued at B, and to continued to increase until C.

Answer:

Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup?  One theory involved a "shocking" start. Another idea is utterly chilling. And one theory is out of this world!  Inside you'll learn just how mysterious this all is, as we reveal the different scientific theories on the origins of life on Earth.Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well. The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now.  The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.

A. Saprotroph

Explanation:

A saprotroph is described as an organism that gains nourishment from organic matter that has started to decay.

As per the situation, the organism that grows on dead trees, consuming the detritus left by another decomposer are saprotroph.

Saprotroph, also called saprophyte or saprobe, are organism that grazes on the nonliving organic matter known as debris at a microscopic level.

Bacteria, fungi, etc are examples of saprotrophs.

Thus, option "A" saprotroph.
