The structure that is found in both plant and bacterial cells but not animal cells is the cell wall. Animal cells have cell membranes instead of a well-developed cell wall.

A Plant cell may be defined as a eukaryotic cell that possesses a true nucleus and certain organelles to accomplish specific functions.

Both plant and bacterial cells are surrounded by a rigid cell wall. The cell wall serves to protect the cells and give them shape. Cell walls in plants are made up of cellulose, while cell walls of bacteria are made up of peptidoglycan.

Therefore, the structure that is found in both plant and bacterial cells but not animal cells is the cell wall. Animal cells have cell membranes instead of a well-developed cell wall.

Answer:

Water in a river can be traced through GIS

Explanation:

With the improvement in observational tool, GIS technique has proved exceptionally helpful in tracing the natural resources. The pixels number and color help us to trace the changes in quantity as well as quality.

For example -

Suppose,  a river and its channel is being traced through GIS.

In year 1991, the number of pixels covering a certain area and of sky blue color signifies large volume , area of water and its good quality respectively

However, after 10 years  image of same are may show a change in previous observation such as reduction in number of blue pixels and also change in color from blue to red signifying increase in pollution level.

GIS can be used in analyzing the data that are related to the place where a natural resource is gotten.

In conclusion, GIS is beneficial in natural resource management.

The brain's hypothalamus controls the endocrine system by regulating the pituitary gland, which is the master gland responsible for the secretion of hormones that affect other glands and bodily functions.

Because it controls the pituitary gland, the brain's hypothalamus ultimately controls the endocrine system. The hypothalamus is a critical part of the brain that provides a link between the nervous and endocrine systems by controlling the pituitary gland, also known as the "master gland".

This master gland secretes various hormones that influence other endocrine glands such as the thyroid gland and pancreas, which are responsible for essential physiological processes like growth, metabolism, sexual maturation, reproduction, body temperature, and blood pressure regulation. The pituitary gland produces several hormones, including growth hormone, endorphins for pain relief, and hormones that regulate fluid levels in the body, exemplifying its central role in the body's hormonal regulation.

Answer:

7.

Explanation:

pH may be defined as the negative logarithms of hydrogen ion concentration. The pH scale is used to determine the acidity and the basicity of the proteins on the pH scale.

Acids has the pH less than 7 whereas the base has the pH more than 7. Since, the cell contains large amount of water, its pH is 7. Water is a neutral molecule and neutral substances has pH nearly equal to 7 when measured on the pH scale.

Thus, the correct answer is option (A).

The mineral used to make wallboard for house interior walls is gypsum (option c).

To make wallboard for the interior walls of a house, you would use the mineral gypsum (option c). Gypsum, or calcium sulfate dihydrate, is a sulfate mineral that is used in construction materials such as plaster and drywall. Wallboard made from gypsum is commonly referred to as sheetrock.

If you were building a house with a basement, you would typically prefer the dominant clay mineral of the soil on your lot to be kaolinite rather than bentonite. Kaolinite is a clay mineral that is less prone to swelling and water absorption compared to bentonite, making it more stable and preferable for a foundation.

The process in which one species evolves into a variety of species is called adaptive radiation or divergent evolution. It involves speciation through branching events and common ancestry.

The process in which one species evolves into a variety of species is called adaptive radiation. It is a mechanism for speciation that occurs when a single species evolves into many new species to fill available niches. This process results in enormous variation in form and function, and is seen in various organisms including flowering plants and hominids.

Divergent evolution is another term used to describe when two species evolve in different directions from a common point. This can be observed in reproductive organs of flowering plants or in the evolution of different hominid species.

A crucial aspect of this process is the concept of common ancestry, which means that related species share a common ancestor. This principle is illustrated in Darwin's concept of branching evolution, where one species branches to form more than one new species over time.

Adaptive radiation is the process where one species evolves into multiple new species, each adapted to different environments or niches. It is a significant part of evolution, exemplified by Darwin's finches.

The most likely location for upwelling would be a coastal area with the right combination of wind patterns, ocean currents, bathymetry, and the presence of kelp forests, all of which point to the presence of nutrient-rich, cold water being upwelled to the surface.

Upwelling typically occurs at the coast where wind-driven currents move away from the land, allowing deeper, colder, and nutrient-rich water to rise up and replace the surface water. This phenomenon is common in areas with persistent winds that blow parallel to the coastline in a direction that causes the surface water to move offshore due to the Coriolis effect. The Coriolis effect is a force that acts on objects moving in a rotating system, such as the Earth, and it causes the water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Kelp forests are often found in these areas because they thrive on the abundant nutrients brought to the surface by upwelling. The ideal location for upwelling would therefore be a coastal region with:

1. Persistent winds that blow parallel to the coastline and in the correct direction to push surface water offshore.

2. A steep continental shelf that allows deep water to be brought up closer to the surface.

3. Cooler sea surface temperatures, which can indicate the presence of upwelled water.

4. The presence of kelp forests, which are indicators of nutrient-rich waters.

By analysing these factors, one can determine the most likely location for upwelling. For example, if the potential kelp forest locations are found along a western coast of a continent in the Northern Hemisphere, and there is evidence of cooler sea surface temperatures and persistent northward winds, then this area would be a prime candidate for upwelling. The cold, nutrient-rich water rising to the surface would support the growth of kelp forests, and the presence of these forests would in turn help maintain the upwelling conditions by providing a physical structure that can dampen wave energy and reduce the mixing of the water column, allowing for more efficient nutrient utilization by the kelp.

Answer:

B. testing explanations

Explanation:

Aristotle defines science as "knowledge of causes by causes. It is demonstrative knowledge".

Science consists of three components: observation, experimentation and laws. It aims at the union between theoretical knowledge, practice and technique. It does not use assumptions, but verification after applying the scientific method.

In short, science is the knowledge that explains phenomena according to laws that have been verified by experimental methods. Accordingly, we can say that what differs science from other subjects such as arts and history is that science depends on testing explanations.
