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.

8. D. All 4 statements are correct.

10. False

Explanation:

The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.

In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.

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.

Thus, in this way, phenotype is dependent on genotype of the organism.

3. a process of breeding organisms because of their specific traits

Answers

Answer:

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.

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.

C. The process of obtaining energy requires sugar.
D. They have organelles that are surrounded by membranes. ​

Answers

Only animal cells have the process of obtaining energy through sugar. Plants on the other hand undergo photosynthesis, which uses sunlight instead of sugar.

Answer:

B. They do not have a rigid outermost layer.

Explanation:

Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.

Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.
