Osmosis does not require an additional input of energy from the cell.
Osmosis is considered to be a type of
active transport
endocytosis
passive transport
exocytosis
Answer:
Osmosis is considered to be a type of
active transport.
Explanation:
Answer:
passive transport
Explanation:
Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

Which statement about DNA is NOT correct?
O DNA is found in the nucleus of eukaryotes
O DNA is single stranded
O Deoxyribose is the sugar in DNA
o there are two single ring nitrogen bases in DNA
Answer:
B (2nd Option): DNA is single-stranded
Explanation:
A is correct: DNA is indeed found in the nucleus of eukaryotes.
B is incorrect: Although there can be single strands of DNA (ssDNA), DNA is usually double-stranded which is how it forms its characteristic double-helix shape.
C is correct: Deoxyribose is indeed the sugar in DNA (Deoxyribonucleic Acid)
D is correct: The two single ringed nitrogenous bases in DNA are thymine and cytosine, while the other two (Adenine and Guanine are double ringed.

Explain what ATP is and how energy is stored/released by this molecule.
Need help now please
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
Patients with a genetic condition known as cystic fibrosis struggle with symptoms such as lung and digestive problems. At the cellular level, the cells of patients with the disease do not transport water or other materials out of the cell efficiently. Therefore, patients’ cells have a build up of water and other substances inside the cell. Which of the following best describes how cystic fibrosis impacts cells?
Answer:
One pair of chromosomes includes a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene is large and complex — in fact, more than 1,000 different CF-related mutations have been identified.
In most people, the CFTR gene helps regulate the flow of salt and fluid in and out of cells. But if there is a mutation in this gene, chloride, a component of salt, gets stuck inside the cells and a thick, sticky mucus starts to build up inside the body.

Describe the steps of protein synthesis in a eukaryote.
The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.
The second step is translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.
Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.
What is protein synthesis in a eukaryote?The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.
Transfer RNA transports amino acids to the location where proteins are synthesized. We are left with a polypeptide after this procedure.
The primary level of regulation of eukaryotic gene expression is transcription.
Therefore, the process of transcription involves an enzyme-producing messenger RNA (RNA-polymerase).

isabella works for an environmental safety group. her group wants to answer the question “to what lengths must we go to protect plants and animals?” why is her groups research question flawed?
Answer:
In this case, the question asked is "To what lengths must we go to protect plants and animals?", which is not specific and cannot be used for scientific research.
The ecological researches for the safety of the environment involves the protection of the plants and the animals on the basis of their number and vulnerability to extinction. Almost all the length of the plants are ecologically important and can decrease in number due to the changes in the environment, the length is not a parameter to determine the protection boundary.
Which of the following is an example of overlapping development? O A. Learning to ride a bike B. Learning to walk at the same time you are learning to talk O C. Learning to walk O D. Learning to use a fork
Answer: b
Explanation: i just finished the test
The statement (B) is an example of overlapping development.
What do you mean by overlapping development?In the overlapping development process, the upstream activity may share available preliminary design information with the downstream activity and enables the downstream activity to be started earlier.
Moreover, overlapping tasks are tasks that are executed either at the same time or sequentially. They usually occur if more than one person works on a single project, producing multiple versions when only one version is needed. Overlapping isn't exclusive to tasks; it also occurs in your schedules.
Therefore, overlap is thought to be important as: (1) a means of compressing a maximum amount of information into short sequences of structural genes; and (2) as a mechanism for regulating gene expression through translational coupling of functionally related polypeptides.

What is kinetic energy and how is kinetic energy related to the temperature of a substance?
Answer:
Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The temperature of gases is proportional to the average translational kinetic energy of atoms and molecules. The motion of individual molecules in a gas is random in magnitude and direction.

Which of these is the correct amino acid chain produced from the DNA template strand?
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Serine - Leucine – Proline – Asparagine – Lysine – Arginine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine – Phenylalanine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine - Serine
The correct amino acid chain produced from the DNA template strand will be Arginine – Leucine - Proline – Asparagine – Lysine – Arginine. The correct option is A.
What is amino acid?Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.
Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.
A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).
There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
The amino acid sequence for the given template will be:
3' AGGUUACCGAAUAAACGU 5'
So, as per three letter code, the amino acid chain will be:
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Thus, the correct option is A.

What forms as a result of the wind's frictional force on water?
O deep sea currents that move in a path opposite to the wind currents
O surface currents that move in a path opposite to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path similar to the wind current
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.
