Magma is the molten natural material from which all the igneous rocks are formed. Volcanism is the phenomenon of magma onto the surface of the Earth.
What is Magma?Magma is the molten or the semi-molten natural material from which all the igneous rocks are formed. Magma is found beneath the surface of the Earth planet, and evidence of magmatism has also been discovered on the other terrestrial planets and some of the natural satellites.
Volcanism is the phenomenon of the eruption of molten rocks or magma onto the surface of the Earth or the solid-surface planet or moon, where the lava, pyro-clastics, and the volcanic gases erupt through a break in the surface which is called a vent.

Describe the connection between limiting factors and invasive spicies
Answer: factors that limit a population size are limiting factors. Biotic potential is the amount of organisms that could be supported in an ecosystem if plenty of resources were available. Factors that cause a population to increase are 1)births: the number of births in a population in a certain period of time. 2) immigration: when organisms move INTO a population.
Explanation:
some examples of limiting factors are natural hazards, amount of food, amount/quality of water and air, predators deforestation.
Why is fertile soil a valuable resource?
Humus is present in it
It takes a very long time to make it
It is quickly being renewed

Reset the carrying capacity back to 200. Trophy hunters move into the area, leading to an increased death rate, which decreases the growth rate r to 0.15. How would this impact the population size? (Hint: Look at when the population reaches its carrying capacity, look at the T value)
Question 14 options:
The kudu would grow at a very slow rate for 30 years and then the growth rate would slow down.

Molecular anthropology ___________________ Question 1 options: uses genetic analysis of a DNA sequence to assess evolutionary links. is the specialty of the most important member of an archaeological excavation project. studies early hominins through fossil remains. uses microscopic phytolithic analysis to study molecular evolution. uses archaeological survey techniques to gather its data.
Answer:
The correct answer is ''uses genetic analysis of a DNA sequence to assess evolutionary links.''
Explanation:
Molecular anthropology is a relatively recent branch, it refers to the study of biological phenomena (genetic study) at molecular levels, that is, biochemical, it allows us to understand and expand our knowledge about the evolution of the species and the complex phenomena of microevolution . It is closely related to other fields of anthropological study, among which we can mention primatology and genetics.Through molecular anthropology we are more aware of kinship, therefore, we can know human evolution over the centuries .

What is the reaction for photosynthesis?
Answer:
The carbon dioxide (CO2), water (H2O), and sunlight become new energy (stored in a sugar molecule called glucose, C6H12O6) and oxygen (O2). The original elements that make up carbon dioxide and water are never lost or destroyed during the process.
Answer:
I would most likely react in a positive way. Photosysntesis is pretty cool! I would probably say woow! or gasp loudly. However reactions to vary based on the individual i know many people who find the color green disgusting. For this reason they would probably say "ew" or "urgh" and be fairly negative.

Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills. One of the ways that humans cause the most air pollution is by burning fossil fuels. Fossil fuels include coal, oil, and natural gas
What if cellular respiration did not occur
Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

refers to the Linnaeus' method of naming species
using a unique two-word name made up of the genus and species name.
O cell organelle
O level of cladistics
O binomial nomenclature
O method of taxonomy
Answer:
binomial nomenclature
Explanation:
Binomial nomenclature as the name implies (binomial = two, nomenclature = naming) is a system of naming organisms that comprises of two unique Latin word names. The binomial nomenclature is a system of naming that was proposed by the man referred to as the FATHER OF TAXONOMY, CAROLUS LINNAEUS.
According to this system of naming organisms, the two names are the generic and specific epithet of the organism respectively. For example, in dog, which is Canis familiaris, Canis is the generic name while familiaris is the specific name.
