Which diagram correctly shows how heterozygous alleles are found on homologous chromosomes?
Answers
Answer:
The answer is I think D
Explanation:
The diagram that correctly shows how heterozygous alleles are found on homologous chromosomes is ; Aa ( The first diagram )
Heterozygous alleles are different alleles gotten/inherited from the genes inherited from each parent cells ( i.e. from each parent ). while
Homologous chromosome is a pair of chromosomes containing same gene sequence, chromosomal length and posses the same centromere location in each chromosome in the pair.
Hence we can conclude that The diagram that correctly show how heterozygous alleles are found on homologous chromosomes is the first diagram ( Aa ).

Jorge is conducting an comparative experiment where he is comparing the heights of adults who grew up taking a certain vitamin and adults who did not. He finds that those who took vitamins are, on average, 2 cm taller. What is a major limitation of his experiment?
Answers
Answer:
Major limitation of Jorge's experiment are -:
Vast amounts of data can be obtained.He does not prove definitively that a person is taller because of vitamins. No association between vitamins and height can be seen.Explanation:
ABOUT VITAMINS -:
A vitamin is an organic molecule that is an important micronutrient that an organism requires in limited amounts for the proper functioning of its metabolism (or a chemically closely connected group of molecules, i.e. vitamins). In the body, basic nutrients can not be synthesized in adequate amounts, either at all or not, and must therefore be ingested via a diet.
Hence, the major limitations of the experiment are mentioned above.

how do materials that cannot diffuse through the cell membrane get into the cell?
Answers
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

Urey and Miller cooked a "Primordial soup" with Hadean gases, water and electricity to make ___, ___, ___, and ___.
Answers
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

1. Krista is conducting an investigation to determine how much fertilizer is best for her sunflower plants. She uses five plants and gives each a different amount of water for six weeks. Each week, she measures the height of each plant. She records her findings in a chart.
Answer the following:
1a. What are the independent and dependent variables?
1b. What should she record in the chart?
1c. What kind of scientific investigation is this example?
Answers
Answer:
1a. Independent variable: WATER
Dependent variable: HEIGHT
1b. the height of each plant every week
1c. Experimental investigation
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter. In this case, the independent variable is the AMOUNT OF WATER given to each plant.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is HEIGHT.
(1b) In an experiment, the dependent variable is the variable that is recorded. Hence, in this experiment, the HEIGHT of each plant every week is recorded in the chart.
1c) 1c. This investigation is a type of EXPERIMENTAL INVESTIGATION because it involves testing how the independent variable affects the dependent variable.
A scientist discovers several new prokaryotic organisms near a deep seafloor vent. Which best describes the general characteristics of these organisms?
A.
colonial, autotrophic
B.
multicellular, heterotrophic
C.
single-celled, autotrophic
D.
multicellular, autotrophic
Answers
Answer:
a,
Explanation:
The general characteristic of the new prokaryotic organisms is single-celled, autotrophic. Therefore, the correct statement is option C.
What are prokaryotic organisms?Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They can be either autotrophic or heterotrophic.
Deep seafloor vents are chemosynthetic organisms, which produce organic molecules using energy from chemical reactions. Prokaryotic organisms include bacteria and archaea and are the most common types of organisms found in deep-sea vents, and many of these are chemosynthetic and autotrophic.
The new prokaryotic organisms discovered near a deep seafloor vent are single-celled and autotrophic which can produce their food through chemosynthesis.
Therefore, new prokaryotic organisms near a deep seafloor vent are that they are single-celled and autotrophic.
