a cell is placed in solution which has the same solute concentration as the inside of the cell isotonic. because the concentration is the same on both sides of the membrane which direction will the water move via osmosis

Answers

Answer 1

Answer:

If a cell is in a medium with the same concentration of solutes with respect to intracellular space —isotonic— there will be no movement of water because there is no osmotic gradient or osmosis.

Explanation:

Osmosis implies the passage of water through a semi-permeable membrane from a place with a lower concentration of solutes to one where the concentration of solutes is higher. This difference in solutes concentration on both sides of the membrane produces an osmotic gradient, where the water will move towards the space with the highest concentration of solutes.

If a cell is in an isotonic medium —the same concentration of solutes inside and outside the cell— there is an equilibrium and the osmotic gradient is non-existent, so there is no movement of water or osmosis.

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal

Answers

Answer:

Nervous tissue can generate and conduct electrical signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

    The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

There are two different types of cell transportation. Which of the following requires energy?

a. Facilitated Diffusion

b. Active Transport

c. Osmosis

d. Simple Diffusion


please help :))​

Answers

Answer:

The type of cellular transport that requires energy is active transport (option b).

Explanation:

Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.

In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.

The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.

    The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.

Compare and contrast the TWO classes of "seeded "plants.​

Answers

Answer:

The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.

Explanation:

The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.

Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.

Molecules that make up living things and contain carbon are called __________ molecules.

Answers

Living organisms contain inorganic compounds (mainly water and salts) and organic molecules. Organic molecules contain carbon; inorganic compounds do not. Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen

Molecules that make up living things and contain carbon are called organic molecules.

Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.

Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.

About organic molecules:

All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.

These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups.

Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.

Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.

Hybridization - a method that unionizes gametes of differing genes to create a new individual

Recombinant DNA - cultured DNA molecules from different biological sources

Selective breeding - a process of breeding organisms because of their specific traits

Explanation:

In biology, hybridization is the process of creating a hybrid by combining gametes of different species or varieties. An example of a hybrid is a liger - an offspring of a lion and a tiger.

Recombinant DNA is DNA created in the process of genetic recombination. Genetic material from multiple sources is combined, creating sequences that do not occur in the genome naturally.

Selective breeding is the process of breeding organisms with desirable characteristics. For example, a good dog breeder will breed only two completely healthy dogs in order to make sure that the puppies don't have any health issues often associated with the breed.

what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)​

Answers

Answer:

They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.

Example: Dominant blue flower (Bb)  mixed with recessive yellow flower (bb)

        B            b

b       Bb          bb

b       Bb          bb

There is a 50/50 chance the offspring will be either blue or yellow

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.

What is phenotype?

A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.

When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
