Q: What is the name of the chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents? Read this paragraph and choose the correct option from the provided answers: A Punnett square is a chart that allows you to easily determine the expected percentage of different genotypes in the offspring of two parents. An example of a Punnett square for pea plants is shown in Figure below . In this example, both parents are heterozygous for flower color ( Bb ). The gametes produced by the male parent are at the top of the chart, and the gametes produced by the female parent are along the side. The different possible combinations of alleles in their offspring are determined by filling in the cells of the Punnett square with the correct letters (alleles). At the link below, you can watch an animation in which Reginald Punnett, inventor of the Punnett square, explains the purpose of his invention and how to use it. http://www. dnalc. org/view/16192-Animation-5-Genetic-inheritance-follows-rules-. html. Choices: - periodic square - DNA helix - Trafalgar Square - punnett square A:
punnett square

Q: What do you call the strands of dna wrapped around proteins, which are located inside the nucleus? Read this paragraph and choose the correct option from the provided answers: Inside of the nucleus, you will find the chromosomes . Chromosomes are strands of DNA wrapped around proteins. They contain genes , or small units of genetic material (DNA) that contains the code for the creation of a protein. Human cells have 46 chromosomes (23 pairs). There are hundreds to thousands of genes on each chromosome. Choices: - receptors - ribosomes - fibrils - chromosomes A:
chromosomes

Q: Q: Which organ secretes estrogen? Read this paragraph and choose the correct option from the provided answers: The ovaries release the eggs and secrete estrogen. Choices: - the testes - the thyroid - the kidney - the ovaries A:
A: the ovaries

Question: Q: What results when gas particles rebound off the walls of their container? Read this paragraph and choose the correct option from the provided answers: Pressure is what results when gas particles rebound off the walls of their container. The basic unit of pressure is the newton per square meter (N/m2). This combined unit is redefined as a pascal (Pa). One pascal is not a very large amount of pressure. A more useful unit of pressure is the bar, which is 100,000 Pa (1 bar = 100,000 Pa). Other common units of pressure are the atmosphere (atm), which was originally defined as the average pressure of Earth's atmosphere at sea level; and mmHg (millimeters of mercury), which is the pressure generated by a column of mercury 1 mm high. The unit millimeters of mercury is also called a torr, named after the Italian scientist Evangelista Torricelli, who invented the barometer in the mid1600s. A more precise definition of atmosphere, in terms of torr, is that there are exactly 760 torr in 1 atm. A bar equals 1.01325 atm. Given all the relationships between these pressure units, the ability to convert from one pressure unit to another is a useful skill. Choices: - light - pull - weight - pressure A:
Answer: pressure

Q: What process is at work when warm air or water rises, and cool air or water sinks? Read this paragraph and choose the correct option from the provided answers: Warmer, lighter air is more buoyant than the cooler air above it. So the warm air rises. The cooler air is denser than the air beneath it. So it sinks down. This is convection: warm air rises, and cool air sinks. Warm fluids can undergo convection as well. This is described in the chapter Plate Tectonics . Choices: - evaporation - radiation - moisture - convection A:
**Answer**
convection

The thylakoid membranes contain molecules of the green pigment chlorophyll. Choices: - a photon - a nucleus - a stem - a chloroplast A:
(A).
a chloroplast
