( Atoms) are the basic building blocks of all matter. It was once thought that an atom was the smallest particle of matter but
scientists discovered that there are smaller subatomic particles that make up the atom. There are (Three) basic subatomic particles:
the (proton), the (neutron), and the (electron) the number of protons is called the (atomic number) . The proton is the particle that is used to identify the (element). Every element has a specific number of protons. No two elements will have the (same) number of protons. For example: an atom that has six protons will be a (carbon) atom, (All) carbon atoms will have six protons. If you have an atom that has (two) protons, you have an atom of helium (like the gas that we fill (balloons) with). No other element will have two protons.

Answer:
Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.
Explanation:
En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian hotspot? Explain using evidence and reasoning.
Answer:
Find the explanation below.
Explanation:
The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.
This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.

A truck carrying fertilizer crashed near a stream within a few miles from this karst feature. The fertilizer spilled into the stream and was carried towards the sink hole. What effect will this have on the karst aquifer? Would you want to drink water from this aquifer?
Answer:
Eutrophication effect
Explanation:
The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.
Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the multiplication of phytoplankton (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.
Little by little begin sedimentation, caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light to reach deeper areas. The overgrowth of phytoplankton on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions. Decomposing processes and fermentation increases, producing a bad smell.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae produce toxins and interrupt the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals.In the third layer, there is no oxygen, so life is not possible for animals or plants.In the fourth layer, there are animals and plants remains in the process of sedimentation.At the bottom, there is organic matter and anaerobic bacteria that are in charge of decomposition and fermentation, also producing toxic gases and smell.

Write a paragraph describing the function of the endomembrane system? Include these terms: DNA, RNA, Ribosome, Endoplasmic Reticulum, Golgi Apparatus, plasma membrane, secretory vesicle, free ribosome, bound ribosome, protein.
Answer:
Please find the function of the endomembrane system below.
Explanation:
The endomembrane system is a system of membranous organelles in eukaryotic cells which plays the collective role of synthesis, modification, packaging and transportation of lipids and proteins within the cell. The organelles involved are endoplasmic reticulum, Golgi apparatus, vesicles and plasma membrane.
DNA, which is the genetic material in living cells encodes genetic information. The information in DNA is transcribed in the nucleus into a RNA molecule, which is then translated in the ribosomes (organelle for protein synthesis) into PROTEINS. Ribosomes can either be free or membrane-bound depending on whether it produces proteins that are used in the cell or are exported out of the cell respectively. However, ribosomes are attached to the surfaces of endoplasmic reticulum making them called ROUGH ENDOPLASMIC RETICULUM. This makes rough endoplasmic reticulum associated with protein production/synthesis.
The synthesized proteins is then packaged and modified in the GOLGI APPARATUS, after which it is transported by SECRETORY VESICLES that transports it to the PLASMA MEMBRANE for exocytosis.
what would happen to your body of blood pressure didn't work as it should?
Answer:
Vision problems. Heart attack. Stroke.
Explanation:
Answer:
Many things.
Explanation:
Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.
Too high BP(hypertension):
If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.
Too low BP(hypotension):
If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

A sports medicine major wants to conduct a experiment to determine if there there's a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest tenth, if necessary.
leg press (reps) 12 | 32 | 7 | 11 | 23 | 28 | 15 |
40-yard dash (s) 8.6 | 14.6 | 7.1 | 8.3 | 11.9 | 13.4 | 9.5 |
Answer:
The correct answer is the equation of the line of best fit is y=0.11x+4.54, and it would take the player 6.96 seconds to run.
Explanation:
Using technology, we calculate the line of best fit; we first enter the data points as a scatter plot, then run the regression tool, which gives us y=ax+b, where a=0.11 and b=4.54.
We now use this equation, y=0.11x+4.54, to calculate the amount of time it would take a player to run 40 yards if the player can do 22 leg-press reps:
y=0.11(22)+4.54=6.96.

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?
Answer:
Cleanable
Explanation:
Cleanability refers to the ease with which microorganisms or particles can be removed from the equipment used in food production. To be cleanable the roughness of the machine being employed in production is not expected to exceed 0.8μm.
The Atomic Force Microscope is used to measure the surface roughness of machines. Cleanability is important as it ensures that the machines used in food production are safe.
When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.
The soil referred to her would be dirt because we are talking about a food handler.
Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.Read more at; https://brainly.in/question/40223031
