Ouabain is a specific inhibitor of the active transport of sodium ions out of the cell and is therefore a valuable tool in studi

Kay [80]

Answer:

1. Part A: No

2. Part B: Yes

3: Part C : Yes

4: Part D : No

Explanation:

1) Part A: Facilitated diffusion of glucose into a muscle cell:

No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose

2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:

Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.

3) Part C: Uptake of potassium ions by red blood cells:

Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.

4) Part D: Active uptake of lactose by the bacteria in your intestine

No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.

How does wet and dry barometer work?? Thnx

tatiyna

Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.

Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

I hope this helps!

Answer:

Hyphae: Cell filaments,mostly septate

Mycelium: Mass of hyphae

Molds: mostly filamentous, Yeasts: non-filamentous,unicellular fungi

Budding yeasts divide asymmetrically.

Dimorphic fungi: yeast-like at 37°C, mold-like at 25°C.

Fungal spores are reproductive spores (unlike bacterial spores). Used to differentiate fungi.

Growth in acidic, low-moisture, high osmotic pressure environments.

The thallus (body) of a mold or fleshy fungus consists of long filaments of cells joined together; these filaments are called hyphae. Hyphae can grow to immense proportions. The hyphae of a single fungus in Oregon extend across 3.5 miles.

In most molds, the hyphae contain cross-walls called septa (singular: septum), which divide them into distinct, uninucleate (one-nucleus) cell-like units. These hyphae are called septate hyphae. In a few classes of fungi, the hyphae contain no septa and appear as long, continuous cells with many nuclei. These are called coenocytic hyphae. Even in fungi with septate hyphae, there are usually openings in the septa that make the cytoplasm of adjacent "cells" continuous; these fungi are actually coenocytic organisms, too.

Mycelium a mass of long filaments of cells that bring and intertwine, typically found in molds.

Steroid hormones exert their action by ________. A. entering the nucleus of a cell and initiating or altering the expression of

Blizzard [7]

Answer:

The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.

Explanation:

Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.
