Answer:
usually yes
Explanation:
Taxonomy is the science of naming and classifying organisms based on structural and genetic evidence. It's a critical component of biology, helping to organize the evolutionary history of organisms. The modern taxonomic systems use genetic methods for a more precise classification.
Explanation:Introduction to TaxonomyTaxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence. Swedish botanist Carolus Linnaeus was a key figure in the establishment of this system.
The Science of TaxonomyTaxonomy is a critical component of biological studies. It helps organize humans and their evolutionary ancestors, both spatially and temporally. Two types of evidence focused on in taxonomy are morphologic (form and function) and genetic.
Modern Taxonomy: The Role of GeneticsIn the modern era, genetic methods have become a standardized way to compare all living organisms, providing a more defined and accurate classification system. These methods have become integral to the science of taxonomy.
Similarities and Differences: Homologous StructuresOrganisms that share similar physical features and genomes are usually more closely related. Such overlapping features, known as homologous structures, stem from developmental similarities that are based on evolution.

A species with 12 protons and 10 electrons is the magnesium ion with a plus 2 charge. Option C is correct.
Magnesium (Mg²⁺) is the cation of magnesium, the metal cation of magnesium divalent, and the metal dication of magnesium monoatomic. It has the functions of a cofactor.
It is mainly used in the form of Magnesium hydroxide in the milk of Magnesia, a white, slightly alkaline, water-soluble suspension of magnesium hydroxide, formulated at approximately 8% w/v.
Magnesium has 2 electrons in the outermost orbit, the 3s orbit. It can donate 2 electrons out of 3s orbit and achieve +2 charge. Due to the octet principle, the magnesium atom donates 2 electrons to form a stable octet.
So the correct option is option C.

SimilarityAlthough rainforests and deserts are very different, they do have something in common. They both have mountains and steep canyons.
What defines a desert?One thing all deserts have in common is that they are arid or dry. Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall.
What is tropical forest?A tropical forest is a type of forest found in areas with high regular rainfall and no more than two months of low rainfall, and consisting of a completely closed canopy of trees that prevents penetration of sunlight to the ground and discourages ground-cover growth.

Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. By plotting the
number of survivors per 1,000 individuals on a log scale versus time, three basic patterns emerge, seen here in the graph. Most
individuals in this population produce many thousands of offspring, most of whom die right away. Relatively little effort or
parental care is invested in each individual. Once this initial period is over, survivorship is relatively constant.
Predict which type of organism could be represented by survivorship curve type III.
Answer:
it's a
Explanation:
The survivorship curve that represents organisms with high initial mortality and constant survivorship is characteristic of r-selected species, such as insects or small rodents.
The survivorship curve you're describing, characterized by high initial mortality followed by relatively constant survivorship, is typical of r-selected species.
These are organisms that exhibit a reproductive strategy emphasizing quantity over quality.
They invest minimal effort in parental care and produce a large number of offspring, many of which do not survive to reproductive age.
R-selected species are often found in unstable or unpredictable environments, where the ability to reproduce quickly and produce a large number of offspring can be advantageous.
These species typically have a shorter lifespan, mature quickly, and have high reproductive rates.
Examples of organisms represented by this survivorship curve include insects, small rodents, and some species of fish.
Insects, for instance, often lay numerous eggs or give birth to many offspring, but only a small fraction of them survive to adulthood.
This strategy allows them to adapt to changing environmental conditions and maintain their population.
The curve's initial steep decline is due to the high mortality during early life stages, which is characteristic of many r-selected species.
The subsequent plateau indicates that the survivorship rate remains relatively stable over time, as the surviving individuals reach maturity and their mortality rate becomes more constant.
In contrast, K-selected species, characterized by low reproductive rates and significant parental care, often display a different survivorship curve.
The high survivorship at the beginning of life and a gradual decline as individuals age.

Explanation:
Photosynthesis. Plants pull in carbon dioxide out of the air through photosynthesis. ...
Decomposition. ...
Respiration. ...
Combustion.
Final answer:
The Carbon Cycle includes six steps: photosynthesis, respiration, decomposition, ocean uptake, interactions with rocks and fossil fuels, and human activities, all of which involve the movement and transformation of carbon through different forms in the Earth's ecosystems.
Explanation:
The Carbon Cycle is a series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. The six steps of the Carbon Cycle are:
Photosynthesis: Plants draw carbon dioxide out of the atmosphere and convert it into carbohydrates through photosynthesis.Respiration: Animals and plants respire by using oxygen to convert carbohydrates into energy, returning carbon dioxide to the atmosphere.Decomposition: The breakdown of dead organisms and organic waste by soil microorganisms releases carbon dioxide back into the atmosphere through soil respiration.Ocean Uptake: Carbon dioxide is dissolved in ocean water, where it can be used to form carbonates or taken up by marine organisms.Rocks and Fossil Fuels: The formation and weathering of rocks can store carbon for long periods, and burning fossil fuels releases carbon back into the atmosphere.Human Activities: Activities such as burning fossil fuels and deforestation increase the level of carbon dioxide, disrupting the natural carbon cycle.These steps form a complex pathway through which carbon atoms cycle through the Earth's ecosystems, impacting climate and supporting life on Earth.

Explanation:
my brain smart and big
The high amount of moisture in the air, known as humidity, describes the climate of Houston, Texas, where the humidity makes the air feel 'heavy.'
The statement about the air over Houston, Texas, containing a high amount of moisture refers to the climate of Houston. Climate encompasses the long-term patterns of temperature, humidity, wind, precipitation, and other atmospheric conditions in a region. In Houston, the high humidity contributes to the sensation of the air feeling "heavy" because warmer air can hold more moisture, making the humidity levels a significant aspect of the area's climate. The concept of humidity is directly related to the water vapor content in the air, which is why locations with high temperatures, such as Houston, often experience high humidity levels, affecting the local weather and, over time, defining the climate.
