A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. Therefore, option (1) is correct.

The gold foil or Rutherford scattering experiment showed that the atom has a small, compact, positively charged nucleus. The gold foil deflected few alpha particles, indicating that the atom is primarily empty space. A small percentage of particles deflected or bounced back, revealing a concentrated positive charge in a limited region of the atom.

This led to Ernest Rutherford's atomic model, often known as the planetary model, where the atom has a tiny, positively charged nucleus at the centre and mostly empty space where electrons orbit it. Therefore, option (1) is correct.

Meningitis is usually caused by a viral infection but can also be bacterial or fungal. Vaccines can prevent some forms of meningitis.

Symptoms include headache, fever, and stiff neck.

Depending on the cause, meningitis may get better on its own, or it can be life-threatening, requiring urgent antibiotic treatment.

Considering the definition of acceleration, since the speed does not change, his acceleration is zero.

A body has acceleration when its speed varies over time, either in magnitude or in direction.

In other words, the acceleration of a body is a physical magnitude that indicates the variation in speed experienced by a body in its displacement as a function of the time spent on it.

Therefore, a moving body is changing acceleration as its speed changes. As speed is a magnitude that considers the speed of a mobile and its direction, the changes that occur in speed will be due to variations in speed and/or direction.

Hunter’s velocity was 4.5 m/s. At the end of his race, his velocity was the same. Since the speed does not change, his acceleration is zero.

Answer:

During metaphase 1, the chromosomes line up in the middle of the cell. The way the chromosomes line up is random, or independent. This independent alignment results in different possible arrangements or assortments of chromosomes during metaphase. This in turn results in different sets of chromosomes in daughter cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.  

Explanation:

In metaphase, the typical chromosome is formed by two chromatids joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. During metaphase I, fibers of the spindle apparatus capture chromosomes and take them toward the center of the cell, to the metaphase plate. Each chromosome of the pair joins with a microtubule of only one of the spindle poles, so the two equivalent chromosomes join the fibers of opposites poles.

The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in anaphase I. When they align in the center of the cell, their orientation is random.

Scientists recognize seven living species of sea turtles, which are grouped into six genera. Each sea turtle has both a scientific name and a common name. The scientific name identifies the genus and species, and the common name typically describes some characteristic of the turtle’s body.

Different species of sea turtles like to eat different kinds of food. Sea turtles have mouths and jaws that are specially formed to help them eat the foods they like. And each species of sea turtle eats, sleeps, mates and swims in distinctly different areas. Sometimes their habitats overlap, but for the most part they each have different preferences.

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Both need To organism.

both are relater.

Photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.

Photosynthesis refers to the series of metabolic reactions by which plants use carbon dioxide from the atmosphere and sunlight to produce oxygen and simple carbohydrates (i.e., sugars).

Conversely, cellular respiration is a series of reactions by which aerobic cells use oxygen from the atmosphere and the energy stored in the chemical bonds of foods to produce carbon dioxide and ATP.

Photosynthesis reactions can be divided into light-dependent relations and light-independent reactions.

Moreover, cellular respiration has three stages: glycolysis, the acid citric cycle and oxidative phosphorylation.

In conclusion, photosynthesis removes carbon dioxide from the atmosphere and generates oxygen, while cellular respiration releases carbon dioxide into the atmosphere and consumes oxygen.

At the end of DNA replication, each copy is identical to each other (option A).

Explanation:

The concept of DNA replication implies that, from an original molecule, two identical molecules are obtained.

DNA replication is based on a semi-conservative model, since the double strand is separated, and each strand serves as a mold for the synthesis of a new strand. At the end of the replication, two identical DNA molecules will be obtained, each consisting of an original strand and a new one.

The best evidence that the replication process results in two identical molecules is that, otherwise, an individual's genetic information could vary, which does not happen.

The other options are not correct because:

For this particular reason, weathering as well as the erosion paintings collectively reshape Earth's panorama. The technique of the bodily breaking down the rock.

Weathering has the breaking down or dissolving of the rocks and minerals on this planet's ground. once the rock has been damaged down, the method known as the erosion transports the bits of rock and minerals away. Water, acids, salt, flora, animals, and adjustments in temperature are all sellers of weathering and erosion.

The rock particles that has been broken down into or inside the weathering method are moved to some other place within the course of erosion. Weathering and the erosion paintings collectively reshape Earth's panorama. The technique of bodily breaking down the rock.

Answer:

these continents were joined as a single landmass  

Explanation:

Alfred Wegener proposed the 'Continental Drift Hypothesis' which stated continents were joined into a single great landmass called Pangaea. Pangea was a supercontinent that was assembled during the late Paleozoic and early Mesozoic eras, from about 330 to 200 million years ago. During the early Mesozoic, Pangea began to separate into continents observed today. It is for that reason that the same fossils can be found in very different geographic-climatic regions, evidencing that in the past continents were joined into larger landmasses.

Answer:

B.- Molecule, cell, tissue, organ, organ system, organism

Explanation: Found it in the reading assignment, and double checked it to make sure it was right :)

The molecule, cell, tissue, organ, organ system, and the organism is arranged from least or smallest to the most or largest complex. Thus, option B is correct.

The level of an organization defines the relationship starting from simple to complex arrangements. It starts with the most simple and small order and further goes up to the complex and largest structures.

The molecules are the smallest structures after an atom that combines to form a cell. The cell is the fundamental unit that combines together to make a tissue that further forms an organ. The different organs combinedly form an organ system and finally an organism.

Therefore, the molecule is the simplest and the organism is the most complex.
