Answer:
Smooth Muscle Definition Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. Smooth muscle is composed of sheets or strands of smooth muscle cells. These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins.
Explanation:
c. Resistant bacteria have survived and reproduced at a greater rate than nonresistant bacteria
Explanation:
The antibiotic is no longer effective as it was 20 years ago because the resistant bacterial have survived and reproduced at a greater rate than the non-resistant bacteria.
- The antibiotics have specifically designed to exterminate the disease causing bacteria strain from the body.
- While at that point in time, it is potent and does the work. Along the line, it will cause the structures of some other strains to change.
- This will lead to the development of resistant breeds with time.
- The resistant breed will then be able to survive the onslaught of the antibiotics making it not a good fit.

Steroid hormone
- The cell signaling pathways induced by the steroid hormones regulate specific genes within the cell's DNA. The hormones and receptor complex act as transcription regulators by increasing or decreasing the synthesis of mRNA molecules from specific genes.
- Steroid hormones are not able to target every cell within the body, so the overall response is slower. They bind to receptors on the cell's surface and the receptors aid in helping the steroid hormones enter the cell.
- Hormones work by binding to protein receptors either inside target cells or on their plasma membranes. The binding of a steroid hormone forms a hormone-receptor complex that affects gene expression in the nucleus of the target cell.
- Steroids pass into a cell's nucleus, bind to specific receptors and genes and trigger the cell to make proteins.

Answer:
true
Explanation:
Daylight hours are shortest in each hemispheres winter. between summer and Winter Solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher latitude. the fewer sunlight hours the colder the nights.
Answer:
For chemical reactions where the free energy of the reactants is much greater than the free energy of the products (DGo' < 0), the reaction proceeds spontaneously and the net result is a large ratio of product to reactant (large Keq).
