Answer:
<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.
Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
Answer:
Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions. Pathogens of all classes must have mechanisms for entering their host and for evading immediate destruction by the host immune system. Most bacteria are not pathogenic.
Explanation:
Meiosis<span> and </span>mitosis<span> are both preceded by one round of DNA replication; however, </span>meiosis<span> includes two nuclear divisions. The four daughter cells resulting from </span>meiosis<span>are haploid and genetically distinct. The daughter cells resulting from </span>mitosis<span> are diploid and identical to the parent cell.</span>
Answer:
c.) increased glucose uptake to the liver from blood
Explanation:
During stressful conditions such as facing a mugger, the sympathetic system of the autonomic nervous system is activated. There is a release of stress hormones from the adrenal glands to produce the flight or fight response. One of the physiological events occurring during these conditions is the breakdown of glycogen into glucose in liver cells and the release of glucose into the blood. The release of glucose by the liver increases blood glucose levels. This is done to ensure glucose availability as fuel. There is no uptake of glucose from the liver cells under such emergency conditions.
Answer:
Why doesn't Dr. Logan feel the bed bug feeding on him? The bed bug injects an anesthetic as it feeds. Bed bugs prefer humans over other hosts. Many blood-feeding parasites carry diseases but bed bugs do not.
