Imagine that a species has eight chromosomes (four homologous pairs). if some event occurred that prevented meiosis from occurring after replication, how many chromosomes would this species have after two generations?

Similarities

Diffusion and osmosis are both examples of passive transport.

They transport substances down a concentration gradient.

Difference

Diffusion is the movement of solute particles down a concentration gradient. Osmosis is the movement of water molecules down a concentration gradient.

Passive transport is the movement of particles through a membrane which requires no extra energy. It happens spontaneously because there is an imbalance in the amount of solutes  or difference in concentration inside and outside the membrane. In order to reach equilibrium or a state where the amount of solute or concentration on both sides is the same, some substances have to cross the membrane.

When substances move from a region of high concentration to low concentration, it is said that the substances are moving down a concentration gradient. This process is spontaneous meaning it does not require energy to occur. The opposite is true for active transport which requires additional energy for it to happen.

In diffusion, solutes move from a concentrated area to a less concentrated area.

In osmosis, the water molecules move from an area with more water molecules (lower concentration of solutes) to the area with less water molecules (higher concentration of solutes).

Index fossils delineate the epochs of geologic time. In order for an organism to be considered as an index fossil it must possess at least one of the four characteristics: it must be unique, extensive, abundant and inadequate in geologic time. Most type of organism may be considered distinctive but not widespread which tolerate them to inhabit all over the world. While some are considered abundant that they were able to be developed as the most susceptible to environmental modification and destruction. Just like the trilobites, this is known as a precise example of index fossil for the Paleozoic rocks that is inhabit in all parts of the ocean. They develop new species throughout their being, which is according to some reports, lasted 270 million years from Middle Cambrian time to the termination of the Permian Period. Because of their ability to travel, they tend to dwell in global areas. The trilobites are huge that they can be used in a study even without a microscope and they are also hard-shelled invertebrates which make them petrified effortlessly.

Trilobites are considered excellent index fossils because they were geographically widespread, each species existed for a relatively short period of geologic time, they were abundant, and they have easily distinguishable features.

To understand why trilobites are considered to be good index fossils, we must first look at the four criteria that qualify an organism as an index fossil.

Collectively, these characteristics make trilobites excellent index fossils for determining the ages of rock layers. When scientists find trilobite fossils, they are able to narrow down the age of rock layers to specific periods within the Paleozoic Era.

Using no more than 13 propositions, create a Concept Map to compare and contrast the motor neurons in the somatic and autonomic nervous systems.

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

There are three branches to the ANS; the sympathetic nervous system, the parasympathetic nervous system, and the enteric nervous system.

With conditions like Type 2 diabetes, the damage can happen in many places throughout your body. The most likely symptoms of autonomic nervous system damage include: Heart rhythm problems.

Answer: density-independent

Explanation:

A limiting factor is the one which is responsible for the decrease in the growth , abundance and distribution of the population of a species in an ecosystem. It can be a living agent or a non-living agent. A density independent factor is the one which limits the growth of the population and it does not depend upon the density of the species population. A density dependent factor is the one which limits the growth and abundance of the population of the species on the basis of the density. More the density more profound will be the impact for example a disease is likely to be spread among the members of the population of a species.

The effect of human disturbance on animal is an example of density independent limiting factor as the human beings while using animal products or disturbing their habitats does not consider about the consequence of the affect. But some animals recover this loss by reproducing more progenies but others which cannot may extinct.

Answer: True

The nuclear fuel cycle involves the generation of nuclear energy in a nuclear reactor by utilizing various sources of radiations in a thermal power station. The nuclear fuel is sensitive to impact or friction. If it receives impact or friction, an explosion can occur. Therefore, these fuels should be transported in an appropriate container and should be dump either on shallow land or in water so that dumping does not result in air blast effects or explosion. Hence, final stage of the nuclear fuel cycle involves the spent fuel must be transported, processed, and disposed of properly.  

The type of microscope that requires a nonmetal sample to be prepared for viewing by coating it with a thin layer of a conductive material is the Scanning Electron Microscope (SEM).

A scanning electron microscope (SEM) is a type of microscope that uses electrons to image the surface of a sample. It provides high-resolution, three-dimensional images of the sample's surface topography and composition.

In an SEM, a focused beam of electrons is scanned across the sample surface. When the electrons interact with the atoms on the sample, various signals are generated. These signals, including secondary electrons, backscattered electrons, and characteristic X-rays, are detected and used to create an image.

The electron beam in an SEM is typically generated by an electron gun and focused using electromagnetic lenses. The scanning coils direct the beam in a raster pattern across the sample. By adjusting the beam intensity and scanning parameters, detailed images with high magnification can be obtained.

SEM is widely used in various scientific fields, such as materials science, biology, geology, and nanotechnology. It allows for the visualization and analysis of the surface features, morphology, and elemental composition of a wide range of samples, providing valuable insights into their microstructure and properties.

Matter cycles in different parts of the ecosystem through different processes. Carbon, Nitrogen and water are the main biogeochemical cycles. Thus, the correct option is 1, 2, and 3.

The ways in which an element or compound such as water moves in between various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Matter such as nutrients, cycles through ecosystem via processes that include physical and chemical changes. Example, plants and animals consume and then excrete elements in the physical environment which makes those elements available for yet other plants and animals.

Matter cycling is where matter moves inside the ecosystems. Matter is constantly cycling from place to place in various forms. Matter cycles both naturally and due to human activity.

Which of the following processes cycles matter through different parts of an ecosystem?

More than one answer may be correct.

1. the nitrogen cycle

2. the water cycle

3. the carbon cycle

Answer:

The more fluid there is in the cavity, the less fluid there is generated. This is because the water cushions the force and lessens the friction. For instance, you will notice that if you rub your hands over a balloon filled with water, there isn't much friction at all.

Cumulonimbus clouds are the cloud type that forms from air converging and rising vertically, and is associated with heavy downpours of rain.

The cloud type that can form from air converging and rising vertically, and is associated with heavy downpours of rain, is called “cumulonimbus clouds.” These clouds are commonly known as thunderstorm clouds, which are tall, towering clouds that can reach high altitudes. They form when warm, moist air rises in an unstable atmosphere, causing the air to condense and form large cumulus clouds with vertical development. As the clouds grow taller, they can produce heavy rain, lightning, thunder, and even hail.
