Answer:
The answer is B. base Have a great day!!!
The correct answers are:
1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.
The pH scale is the standard scale that specifies if an aqueous solution is acidic or alkaline/ basic. pH means the relative concentration of hydrogen ions, H+, and hydroxy OH- ions in the solution.
Lower pH values (0 - 7) exhibit more hydrogen ions which means the solution is acidic for instance Strawberry kool-aid add into the water strawberry kool-aid releases H+ ions in the solution.Hence strawberry kool-aid is an acid.
Higher values in the pH scale (7-14) are an indicator for the alkaline or base solution, Alka-seltzer changes pH from 5.4 to 8.3 which means the solution concentration of OH- ions increases and the solution becomes basic.Hence, the solution is basic and the Alka-seltzer gives hydroxy ions in the solution.
Given that baking soda is a strong base and hydrochloric acid is a strong acid, mixing both leads to salt and water as both have almost equal strengths of acid and base neutralization, therefore, the solution would be neutral or slightly acidicOn the basis of the given explanation, we can say that bleach is base as it has a pH value of 9.4 whereas coffee is acidic as pH value is 5.Thus, the correct answer is - 1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.

Answer:
habitat destruction
Explanation:
A forest ecosystem offers a variety of ecosystem services and functions. Prominent among the services offered include habitats to a variety of fauna, watershed protection, carbon sequestration, etc.
When the trees in a forest are removed by clear-cutting, some of the services and functions specific to the tree layers cease. The various habitats provided are destroyed and the organisms that live in these habitats disappear.
Hence, if a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to habitat destruction.

After the transcription mRNA moves from the DNA to the ribosome out of the nucleus to perform the translation and produce amino acid chains. A Ribosome is the site of protein synthesis.
DNA or RNA both nucleic acids are made up of basic units known as nucleotides that join together to form ribonucleic and deoxyribonucleic acid.
RNA polymerase is the enzyme that binds with the DNA molecule and adds complementary sequences to build mRNA.
DNA molecules are double-stranded molecules that are attached to one another by the hydrogen bonds between the nitogenous basses whereas RNA molecules have only one strand in the structure.
mRNA plays the role of messenger between DNA molecule and ribosome molecule to carry out the genetic information coded in the DNA molecule to produce amino acids in the particular sequence to produce protein.
The formation of new DNA from the old DNA is called Replication and the formation of RNA from the DNA is said to be translation.

Asi todas las células son muy pequeñas. ¿Qué limitaciones físicas y metabólicas determinan el tamaño celular? ¿ A qué problemas se enfrentaría una célula enorme? ¿Qué adaptaciones ayudarían a una célula muy grande a sobrevivir?
Answer:
- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio
- Limitación metabólica: en principio no existen limitaciones metabólicas
Explanation:
La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.

Turn to the back of your worksheet to answer the rest of the questions. 1. How are igneous rocks formed? Group of answer choices weathering and erosion into sediments, then deposition and lithification rocks get buried deep in the earth where they melt and then cool rocks are under heat and pressure so they can change rock is split into larger pieces and then dissolves in water where it hardens into rock
Answer and Explanation:
Igneous rocks form most of the earth´s crust. They are the result of the solidification of rocky, molten material, the magma. Rocks are melt in the interior of the earth´s crust or in the mantle, and then, as they are less dense than the other rocks, tend to ascend toward the surface. As they ascend, they get cold and solidify.
There are two kinds of igneous rocks, according to the moment of solidification. Extrusive igneous rocks are the ones formed when the molted material gets to get to the earth´s surface and crystalize there. Intrusive rocks get formed when the magma loses its motility before reaching the surface, ending by crystalizing in the deepness.
