What can you conclude about starch, glucose and their movement across the Visking tubing? , What implications does this have for starch and glucose in the small intenstine?

Answers

Answer:

Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.

Answers

Out of the options given, the density-independent factor is: A. Forest fire. A density-independent factor is a factor that affects a population regardless of its size and density.  

What is cell?

A cell is the basic unit of life that makes up all living things, including animals, plants, fungi, and bacteria. It is the smallest structural and functional unit of an organism that is capable of performing all the functions of life, including metabolism, growth, reproduction, and responding to stimuli. A typical cell is composed of a cell membrane, cytoplasm, and a nucleus (in eukaryotic cells), or a nucleoid region (in prokaryotic cells). The cell membrane is a selectively permeable membrane that surrounds the cell and separates it from the environment, regulating the exchange of materials between the cell and its surroundings. The cytoplasm is a gel-like substance that fills the cell and contains all the organelles and structures necessary for the cell's functions. The nucleus contains the cell's genetic material, including DNA, which controls the cell's activities and is responsible for inheritance.

Here,

A forest fire can have a significant impact on a population, regardless of its size or density. Forest fires can destroy habitats, reduce food sources, and alter the physical environment, which can have a significant impact on the population. A forest fire does not depend on the size or density of a population, so it is considered a density-independent factor.

The other options, such as food source, shelter, and water supply, are density-dependent factors that can impact a population based on its size and density. As the population increases, the availability of these resources can become limited, which can affect the population's growth and survival.

type of inheritance pattern is an example of:

Answers

The type of inheritance pattern that represents an example of three different alleles that determine blood type is known as Codominance.

What is Codominance?

Codominance may be defined as a type of inheritance pattern in which the alleles are able to express themselves independently even when present together. This biological phenomenon is known as codominance.

ABO blood grouping in humans represents an example of codominance in which it is controlled by gene I which has three different alleles. Due to the three different alleles of gene I also represent an example of multiple alleles.

Therefore, the type of inheritance pattern that represents an example of three different alleles that determine blood type is known as Codominance.

How can the type of bedrock under soil affect the characteristics of the soil? *

by absorbing water
by making the soil more fertile
by weathering and becoming new parent material
by providing surface area for nutrient accumulation

Answers

Answer:

by weathering and becoming new parent material

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.

She slammed the sliding glass door shut and stood for a moment, relieved to have something solid between her and the snake on the porch.The glass was cool under her hands despite her pounding heart. She tried to slow her breathing. She was safe, at last, inside. Or was she? How had that snake gotten into the screened-in and walled-up back porch. If it could get in there, it's possible it could get inside where she was as well.Becky wasn't someone who was normally skittish about wild things. She'd handled snakes before, picked up lizards many times, caught frogs in the garage and let them go. But snakes seemed to always catch her off guard. They would turn up when least expected. She would see them out of the corner of her eye and just the surprise of it would make her jump; her adrenalin would pump, her heart would thump, and her panic would take over.What was she going to do? She couldn't just stand there waiting for the snake to decide to leave. What if it were venomous? It didn't look like a viper, but it could be. She would need to get out there soon to water the plants."What this requires is some advanced planning," she said out loud to her cat, Louie. "And, I will probably have to go 'once more into the fray' kitty," she said, looking in the cat's direction for emphasis."First things first, though," she said. The cat meowed back. It often did that, having become used to being talked to. "Let's look that fellow up," Becky said walking to her bookshelf."Let's see, snakes," she said, thumbing through her reptile and amphibian identification book. "It's brown and gray, with some black. With a pattern that looks ... there it is," she said thumping the page so hard that Louie jumped. "Not venomous," she said, triumphantly."It's an oak snake, Louie," she returned the book and strode over to her closet. "Not venomous, but I am still not taking chances," she said.She reached into the closet and pulled out her heaviest jacket. It was lined and stuffed thick with lots of padding. Then she found her mittens and a pair of rubber boots. She knew even non-venomous snakes would sometimes threaten to strike when scared. "And that threat would work on me," Becky said aloud again, though Louie had no idea what she was talking about."It's 90 degrees outside, Louie," she said, "so get the iced lemonade ready for when I return."It wasn't much of a plan, but it was the best she could come up with. With her armor on, she was already sweating when she slowly pushed open the sliding glass door and stepped back on to the porch.She was pretty sure the snake would slither away from her presence. She propped open the outside door, and hoped she could shoo the snake in that direction.Sweat dampened her arms and collected on her face. She spread her arms out, and took a few steps toward the snake. There was so much for it to hide beneath. Becky regretted the rocking chairs and all the plant stands between where the snake was in the corner and the door to the outside.At first it seemed like the snake was just going to remain where it was, flicking its tongue every now and then. Becky waved her arms, lunged in its direction, and stomped her feet. It sat there, coiled in the corner, as if perfectly happy to remain there. In a fit of desperation, she picked up one side of the rocking chair the snake was under and let it drop. The snake jumped, raised its head like it was going to strike, and then stayed right where it was."Snake," Becky said, "This is not how it works. You have got to go." The snake moved its head back and forth, swaying a bit, and that gave Becky an idea.She had read somewhere that snakes can "hear" thanks to the ability to process vibrations through the bone in their jaw. This awareness of vibrations in the ground was one reason it was very hard to sneak up on snakes. She quickly realized that getting the snake out was going to be a lot easier than she had thought.Becky turned on the radio she kept on the porch and lowered it to the ground, pointing in the snake's direction. She adjusted the controls so that the bass was as high as it could go. Then, she cranked up the volume. She envisioned the snake swaying to the sounds of "Dancing Queen," by Abba, and then leaving the porch and going far, far away.Coming back into the house, she began peeling off the now damp armaments she had put on earlier. "Louie, there is more than one way to skin a snake," she said laughing. She watched as the snake uncoiled and moved cautiously in the direction of the door. Bending down to pick up Louie, Becky sighed and stroked his head. "'Cause no one ever wants to skin a cat, sweetie."Review the narrative "Snake Story" and answer the question below:How does Louie the cat help develop the character of Becky?
