Some people argue that evolution, which is generally associated with progressive increases in the

This argument would not be valid because it fails to take into account the mechanisms through which evolution occurs and misunderstands the second law of thermodynamics.

The second law of thermodynamics states that the total entropy of a system must always increase. The argument stating that this law disproves evolution given that evolution can be considered as a decrease in entropy, fails to realize that the second law states that the total entropy must increase, this does not mean that entropy cannot decrease at one point, to then increase more so at another.

The other aspect of evolution that this argument fails to account for is that evolution is a chaotic process. Evolution, though having a final product that may be considered as increasing in organization, is at heart a chaotic process caused by random mutations and the fragile process of natural selection. Therefore, rather than disprove it, the second law of thermodynamics is actually the driving force behind continued evolution.

Which of the following are the reproductive parts of an angiosperm flower? A. anther and ovary B. sepal and anther C. vary and s

Simora [160]

The answer is A. anther and ovary.

The female part of an angiosperm flower is called a pistil and it consists of a style, stigma and ovary. The male part of an angiosperm flower is called a stamen and it consists of an anther and corolla. Thus, among all choices, choice A is the answer.

Choice B - anther is the male part of the flower, but sepal is a protective part of the flower and not reproductive.

Choice D - stigma is the female part of the flower, but sepal is a protective part of the flower and not reproductive.

Choice C - "vary" is not a word, but it is a mistake and it should be "ovary," the answers could be both choice A and C.

Which of the following macromolecules enter the nucleus of a eukaryotic cell through pores in the nuclear membrane? a. rRNAb. ri

Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

identify the types of questions that interest behavior geneticists, and describe the elements of heredity: chromosome, dna, gene

baherus [9]

The interaction between genetics and environment and how this affects behavior, resulting in individual variances, is of particular interest to behavior geneticists.

The environment in this context refers to every external, nongenetic component of our life, including prenatal nutrition and the people and objects in our immediate surroundings.

Chromosomes:

Each of our cells contains 46 chromosomes, 23 from our mother and 23 from our father. Chromosomes are complicated, spiraling molecules formed of DNA that resemble threads and contain genes.

DNA:

We have over 30,000 genes, which are DNA segments that, when activated (expressed), serve as templates for the synthesis of different protein molecules, which serve as the foundation for our physical and behavioral growth.

Genome:

The entire collection of instructions for creating an organism, included in all of its chromosomal genetic material, is called an organism's genome.

Gene:

Combinations of mutations at certain gene locations serve to distinguish us from one another. The majority of human features are not controlled by a single gene acting alone, but rather by a number of genes working together.
