Wear protective gear (goggles, long-sleeved clothes, and gloves) when using acids and bases. Do not allow acids or bases to come in contact with skin or eyes. Limit the amount of acids and bases transported for usage around the house. Cap the bottles of acid and base cleaners tightly.
Pollutants concentrated in the northern part of the Gulf of Mexico often create a dead zone. A dead zone is an area of an aquatic ecosystem that does not have enough oxygen to support sea life. Some of the chemicals that cause the Gulf dead zone come from as far away as Montana. Use this information and what you know of United States geography to select the statement that BEST explains how pollutants from Montana have an impact in the Gulf of Mexico.
Answer and Explanation:
Hello. You did not present the answer options, but we can say that Montana pollutants have an impact on the Gulf of Mexico, due to the Mississippi River. That's because Montana and the Mississippi River are in the same hydrographic basin, which causes Montana pollutants to reach the Mississippi River, which takes these pollutants to the Gulf of Mexico, as the Mississippi River flows into the Gulf of Mexico.
Therefore, we can say that Montana pollutants are easily taken to the Gulf of Mexico and this impacts marine life in an influential way.
where is 70s type of ribosomes found in eukaryotic cells?
Answer:
All prokaryotes have 70S (where S=Svedberg units) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol. The 70S ribosome is made up of a 50S and 30S subunits. Ribosomes play a key role in the catalysis of two important and crucial biological processes.
¿Qué sucede si una célula se encuentra en la fase G0 del ciclo celular? ¿qué células nunca salen de esta fase?
Answer:
las células en fase G0 no se dividen. Un ejemplo de células en fase G0 son las neuronas y las células del músculo de corazón
Explanation:
El ciclo celular es una serie de eventos asociados al crecimiento y división de una célula. El ciclo celular consta de una fase de crecimiento o 'interfase' (la cual a su vez se divide en 3 fases: la fase G1, S y G2) y la fase de división celular (la cual a su vez se divide en mitosis y citocinesis). Sin embargo, hay células que no entran en fase G1 y en lugar de ello se dirigen a un estadio celular conocido como fase G0. La fase G0 es una es un estadio en el cual se encuentran células maduras que no se dividen hasta recibir un estímulo/señal que dispare la entrada de la célula en fase G1, donde la célula sintetiza los ARN mensajeros y proteínas necesarios para las etapas celulares posteriores que conducen a la división celular. Las células en fase G0 no crecen, pero poseen un metabolismo activo. Ejemplos de células en fase G0 incluyen las neuronas, células musculares poli-nucleadas, hepatocitos, etc. (es decir, células maduras y post-mitóticas que son incapaces de reproducirse).

If there is a piece of metal will it still be attracted to the magnetic even if it is outside of the magnetic field? Will the magnetic field line connect to the object?
Answer:
It will still attract.
Explanation:
When you think of it, when some of us were little we used magnets and played with them and would do a "magic" trick. We would put a magnet underneath the table and one on top and move the one underneath which would move the one on top without us touching it.

state one adaptation of nephron in the kidney of a desert mammal
Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.
Explanation:
The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

Which region of Georgia received the most rain during Tropical Storm Alberto?
Use the scenario to answer the following question. A forest ecosystem is home to mountain lions, coyotes, bobcats and deer. The deer eat grass. The mountain tions, coyotes, and babcats eat deer. Hunters began killing large numbers of mountain lions, coyotes, and bobcats. About twenty years later, the deer population had largely increased. The teacher asked the students to explain why the population of deer had a large increase in population size. Which student's argument MOST accurately explains the increase in the deer population? A Student 4: The deer population increased because with fewer mountain lions, coyotes, and babcats there was less competition within the deer population. B. Student 1The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat. D Student 2: The number of deer increased because without mountain , coyotes, and bobcats, the deer longer and had more offspring that also lived longer,
Answer:
A. student 4
Explanation:
The population of deer increase because with fewer mountain lions, coyotes and bobcats there was less competition within the deer population
The correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."
What is food chain?The food chain describes the feeding relationships that exists in nature. Now this ecosystem has the food chain; grass ---> Deer ----> babcats ---> coyotes ----> mountain lions.
Now we are also told that the mountain lions eat the the bobcats and the hunters are killing the mountain lions, coyotes, and bobcats, the predators of the deer hence been removed hence the deer population multiplies.
Therefore, the correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

Answer:
it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.
6;Gravity is the force that keeps planets in orbit around the Sun.
