Answer the following question given this paragraph: The Chromosomal Theory of Inheritance was consistent with Mendel's laws and was supported by the following observations: During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. The sorting of chromosomes from each homologous pair into pre-gametes appears to be random. Each parent synthesizes gametes that contain only half of their chromosomal complement. Even though male and female gametes (sperm and egg) differ in size and morphology, they have the same number of chromosomes, suggesting equal genetic contributions from each parent. The gametic chromosomes combine during fertilization to produce offspring with the same chromosome number as their parents. Q: During meiosis, each parent synthesizes gametes that contain only half of their complement of what? Choices: - receptors - neutrons - atoms - chromosomes A:
chromosomes
Answer the following question given this paragraph: Some prokaryotes form structures consisting of many individual cells, like the cells in Figure below . This is called a biofilm. A biofilm is a colony of prokaryotes that is stuck to a surface. The surface might be a rock or a host's tissues. The sticky plaque that collects on your teeth between brushings is a biofilm. It consists of millions of prokaryotic cells. Q: A biofilm is a colony of prokaryotes that is stuck to what? Choices: - the middle - the bottom - skin - surface A:
surface
Q: Answer the following question given this paragraph: Figure 3.9 (a) A typical human brain weighs about 1.5 kg and occupies a volume of roughly 1.1 L. (b) Information is transmitted in brain tissue and throughout the central nervous system by specialized cells called neurons (micrograph shows cells at 1600 magnification). Specialized cells called neurons transmit information between different parts of the central nervous system by way of electrical and chemical signals. Chemical signaling occurs at the interface between different neurons. Q: What are the specialized cells within the brain called? Choices: - ions - electrons - protons - neurons A:
A: neurons
Question: Answer the following question given this paragraph: The hypothalamus and pituitary gland are located close together at the base of the brain. Q: The hypothalamus and pituitary gland are located near the base of this organ? Choices: - the heart - the lungs - the liver - the brain A:
Answer: the brain
*Question*
Answer the following question given this paragraph: Probability can be used to predict the chance of gametes and offspring having certain alleles. Q: Probability can be used to predict the chance of gametes and offspring having certain what? Choices: - molecules - atoms - particles - alleles A:
**Answer**
alleles
(Q).
Answer the following question given this paragraph: Dialysis Technician Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. When kidney function fails, dialysis must be done to artificially rid the body of wastes. This is a vital process to keep patients alive. In some cases, the patients undergo artificial dialysis until they are eligible for a kidney transplant. In others who are not candidates for kidney transplants, dialysis is a life-long necessity. Dialysis technicians typically work in hospitals and clinics. While some roles in this field include equipment development and maintenance, most dialysis technicians work in direct patient care. Their on-the-job duties, which typically occur under the direct supervision of a registered nurse, focus on providing dialysis treatments. This can include reviewing patient history and current condition, assessing and responding to patient needs before and during treatment, and monitoring the dialysis process. Treatment may include taking and reporting a patient's vital signs and preparing solutions and equipment to ensure accurate and sterile procedures. Q: What is the medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration called? Choices: - tumors - digestion - arthritis - dialysis A:
(A).
