Earlobe type is an inherited trait and can be described as attached or detached. Earlobe type is a ____________ that is coded by
GenaCL600 [577]
Earlobe type is PHENOTYPE, that is coded by a person's GENOTYPE. 
The genotype refers to a team of genes in a person that is responsible for the expression of a particular trait. For instance, a genotype is responsible for the height of a person, whether the person is short or tall depends on the particular genotype that controls the height trait. Phenotype refers to the physical characteristics or physical manifestations of a particular trait. For instance, tallness is a phenotype, it is a physical expression of the genotype that controls height. In the same way, earlobe type is a phenotype that is determined by a person's genotype.

How do you think Darwin came up with his theory?
Wittaler [7]

Answer:

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.

Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.

The theory has two main points, said Brian Richmond, curator of human origins at the American Museum of Natural History in New York City. "All life on Earth is connected and related to each other," and this diversity of life is a product of "modifications of populations by natural selection, where some traits were favored in and environment over others," he said.

More simply put, the theory can be described as "descent with modification," said Briana Pobiner, an anthropologist and educator at the Smithsonian Institution National Museum of Natural History in Washington, D.C., who specializes in the study of human origins.

The theory is sometimes described as "survival of the fittest," but that can be misleading, Pobiner said. Here, "fitness" refers not to an organism's strength or athletic ability, but rather the ability to survive and reproduce.

Heterotrophs convert solar energy into chemical energy true or false
vitfil [10]
I think it is False. Heterotrophs are organisms that cannot make their own food. They obtain it from consuming other organisms. To make this statement true, you would have to replace the word, "heterotoph" with the word "phototroph" or "autotrophs".

What do diffusion and active transport have in common
kramer
This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move ''uphill'', from regions of lower to higher concentration. This process is also called active transport, and requires some form of chemical energy.
