Mendel's experiments demonstrated the law of dominance: traits are inherited as dominant and recessive alleles, and the dominant allele for a trait can mask the presence of the recessive allele. Occasionally, that law is contradicted: offspring exhibit a blend of their parents' traits. For example a red flowering plant when crossed with a white flowering plant would produce a plant with pink flowers. This type of inheritance pattern is called A) codominance. B) multiple alleles. C) incomplete dominance. Eliminate D) heterozygous dominance.

A gene is a subunit of information on a chromosome true or false?

Answers

The gene, is in fact the subunit of information on a chromosome, so this is a true statement. A chromosome is a structure that occurs within cells. It contains the cell's genetic material, which determines how an organism develops. For example, if we are talking about DNA, its molecule is a very long, coiled structure that contains many identifiable subunits known as genes.

the answer is true

How do the two cells made by mitosis relate to each other?

Answers

How Cells Divide

Depending on the type of cell, there are two ways cells divide—mitosis and meiosis. Each of these methods of cell division has special characteristics. One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into two cells that have half the number of chromosomes. Reducing the number of chromosomes by half is important for sexual reproduction and provides for genetic diversity.

Describe the tetracycline group of antibiotics. How do these drugs work? What is their target on a bacterial cell? Which types of bacteria are they effective against?

Answers

Tetracyclines are antibiotics used against a wide range of microorganisms, such as bacteria, chlamydia, rickettsia and some protozoa parasites.
They inhibit synthesis of protein in bacteria by inhibiting the binding of transport RNA and ribosome and are effective against both gram-positive and gram-negative bacteria.

Mother nature and deforestation?​

Answers

Answer: Deforestation is bad for mother nature. The reason for this is because deforestation is cutting down trees and in that way we are destroying mother nature's gifts to us.

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and severe problems for indigenous people. Some deforestation is caused by a combination of human and natural factors like, wildfires and overgrazing, which may prevent the growth of young trees.

Other biologists of Darwin's time had proposed that living things had changed over time. Which feature distinguished Darwin's theory of evolution from the proposals of the other biologists?

Answers

Darwin's Theory

Explanation:

  • Darwin's suggestion that Earth's numerous species are relatives of hereditary species that were not quite the same as the present-day species.
  • The  characterized all the more barely by as an adjustment in the hereditary synthesis of a populace population from generation to generation
  • Charles Darwin (1809–1882) and others, expressing that all types of living beings emerge and create through the regular determination of little, acquired varieties that increase the individual's ability to compete, survive, and reproduce.
  • Darwin's hypothesis of development by regular determination expresses that living things with useful attributes produce more offspring than others.
  • The first planned in Darwin's book name is  "On the Origin of Species" in 1859, by the natural selection is the procedure by which creatures change after some time because of changes in heritable physical or social characteristics.

Explanation:

Which pairings match protozoa with the structures they use to move? amoeba: flagellum; euglena: cilia; paramecium: pseudopod amoeba: pseudopod; euglena: flagellum; paramecium: cilia amoeba: flagellum; euglena: pseudopod; paramecium: cilia amoeba: pseudopod; euglena: cilia; paramecium: flagellum

Answers

Answer:

The correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia

Explanation:

Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.

A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.

Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.

Thus, the correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia
