Answer the following question given this paragraph: Codominance is when two alleles are both expressed in the heterozygous individual. Q: What is it called when two alleles are both expressed in the heterozygous individual? Choices: - weak dominance - low dominance - shared dominance - codominance A:
codominance
Answer the following question given this paragraph: Constriction and dilation allow the circulatory system to change the amount of blood flowing to different organs. For example, during a fight-or-flight response, dilation and constriction of blood vessels allow more blood to flow to skeletal muscles and less to flow to digestive organs. Dilation of blood vessels in the skin allows more blood to flow to the body surface so the body can lose heat. Constriction of these blood vessels has the opposite effect and helps conserve body heat. Q: Constriction and dilation allow the circulatory system to change the amount of blood flowing to which body parts? Choices: - arteries - tissues - muscles - organs A:
organs
Q: Answer the following question given this paragraph: Germ Cells The least mature cells, the spermatogonia (singular = spermatogonium), line the basement membrane inside the tubule. Spermatogonia are the stem cells of the testis, which means that they are still able to differentiate into a variety of different cell types throughout adulthood. Spermatogonia divide to produce primary and secondary spermatocytes, then spermatids, which finally produce formed sperm. The process that begins with spermatogonia and concludes with the production of sperm is called spermatogenesis. Q: Spermatogonia are the stem cells of what male sex organs? Choices: - Epididymis - Prostate - ovaries - testes A:
A: testes
Question: Answer the following question given this paragraph: Amphibians were the first animals to have true lungs and limbs for life on land. However, they still had to return to water to reproduce. That's because their eggs lacked a waterproof covering and would dry out on land. The first fully terrestrial vertebrates were amniotes. Amniotes are animals that produce eggs with internal membranes. The membranes let gases but not water pass through. Therefore, in an amniotic egg, an embryo can breathe without drying out. Amniotic eggs were the first eggs that could be laid on land. Q: What were the first animals to have true lungs and limbs for life on land? Choices: - birds - mammals - reptiles - amphibians A:
Answer: amphibians

Answer the following question given this paragraph: The general trend in electronegativity is that the value increases from left to right across a row in the periodic table and decreases down a column. The most electronegative element is fluorine, which has a value of 4.0. As discussed in the lesson "Trends in the Periodic Table," electronegativity increases across a row as the number of protons in the nucleus increases and therefore has a stronger pull. Electronegativity decreases down a column due to an increased effect of electron shielding in larger atoms. Q: Generally speaking, electronegativity values ______ from left to right across a row in the periodic table and _______ down a column. Choices: - reverse, descend - move, fall - decrease, increase - increase, decrease A:
**Answer**
increase, decrease

Answer the following question given this paragraph: Weight is a measure of the force of gravity pulling down on an object. Buoyant force pushes up on an object. Weight and buoyant force together determine whether an object sinks or floats. This is illustrated in Figure below . Q: What is the measure of the force of gravity pulling down on an object called? Choices: - factor - mass - volume - weight A:
(Answer)
weight
