does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.
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.

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.

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.

Where and how do the high concentration H+ ions get out of the thylakoid?
Answer: here's what I could find on it:
- Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space.
- The concentration of H+ ions is higher inside the thylakoid than it is outside. the ions flow through the channel by diffusion.
Explanation: sorry if that's not what you need.
The hydrogen ions are allowed to pass through the thylakoid membrane of the chloroplast through an embedded protein complex called the ATP synthase.
What is the ATP synthase?ATP synthase is a protein complex which is made up of various enzymes which catalyzes the formation of the energy storage molecules such as ATP (Adenosine triphosphate) using ADP (adenosine diphosphate) and Pi (inorganic phosphate). It is classified under the ligase class of enzyme as it changes ADP molecule by the formation of P-O bonds.
ATP synthase requires energy to form energy storing molecules such as ATP, from adenosine diphosphate (ADP) and inorganic phosphate (Pi). Because of this, ATP synthesis is coupled with the cellular respiration of the mitochondria and electrochemical gradient which is created by the difference in proton (H⁺) concentration across the mitochondrial membrane during the electron transport through the electron transport chain (ETC). In plants, proton gradient is formed in the chloroplast, in the thylakoid lumen and through the thylakoid membrane.

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.
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.

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.
In order for two new cells to be created during mitosis, each cell must receive an identical copy of DNA. In order to accomplish this task efficiently prior to mitosis, a cell will condense DNA into
Answer:
chromosomes
Explanation:
A cell must condense DNA into chromosomes before it can divide mitotically to form two new cells with identical copies of DNA.
The condensation of the DNA happens at the initial phase of the mitosis - the prophase - during which the DNA thickens and condenses to form chromosomes.
These chromosomes then align at the cell's plate during metaphase and they become separated into sister chromatids through the pulling of the spindle fiber at anaphase. Separated chromatids of the same chromosome are then transported to the opposite ends of the cell where they decondense before cytokinesis takes place.
