what organelles are used in passive and active transport
Answers
Molecules can diffuse across membranes via transport proteins, or they can be aided in active transport by other proteins. Organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria and peroxisomes all play a role in membrane transport.

Identify the tonicity of the solution surrounding the cell.
Answers
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).
"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answers
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

6. Methionine
Transcription is a transfer for genetic instructions for DNA to mRNA In the nucleus. But for translation the instructions for mRNA in which is the message, reads and tRNA brings the correct sequence of the amino acids to the ribosome. Then the rRNA helps the bonds form between the amino acids in which its polypeptide which is protein. And makes a polypeptide chain or amino acid chain.

Identify: What are the reactants of aerobic cellular respiration? What are products?
Answers
Answer:
Aerobic breathing disrupts glucose and combines disintegrated products with oxygen that generates water and carbon dioxide. The carbon dioxide is a waste of aerobic breathing because there is no demand for cells.
Cellular respiration reactants:
Glucose and oxygen.
Cellular Respiratory Products:
CO2 and water (H2O); ATP & Heat
Anaerobic breathing: breathing occurring in the absence of oxygen that makes certain ATP still alive to cells.
Explanation:
Cellular Respiration is the mechanism that releases energy in the presence of oxygen by breaking down food molecules.
Cellular breathing = Aerobic breathing
In mitochondria, aerobic breathing takes place.
Some of the energy generated by food decomposition is stored as ATP and some as heat.
ATP is an energy storage molecule used by every cell as its source of energy.
Explain how ATP stores and releases energy
Answers
Answer:
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.
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
