Answer: The correct answer is C) Substitution.
Substitution is a type mutation ( permanent change in the genetic material of the organism) that is caused by the exchange of one base with another.
This can occur during the process of DNA replication when an incorrect base is added in the new DNA molecule and thus replacing the original base pair. This can result in formation of new amino acid ( that result in different protein) or it may form a truncated protein ( when stop codon is produced due to substitution).
Answer:
stratovolcano
Explanation:
B. sandstone
C. clay
D. salt water
Dissolution and precipitation of _______ are the main processes that form limestone caves? The answer is, A. calcite
The correct answer is false.
Lashing out at others is definitely NOT a healthy way of coping with stress. If you become so angry at the people around you that you start yelling at them, it won't do anyone any good - they will just get hurt by your words and all of you may end up feeling even worse.
This doesn't mean that you should keep your feelings bottled up - however, it is best to focus your stress on other things, such as working out, or doing yoga, or something that you enjoy in order to relieve that stress instead of hurting your loved ones.
An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.
A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.
The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.
Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

Answer:
Forest Ecosystem
An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.
Biotic Factors by Type
The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:
shrubs, flowering plants, ferns, mosses, lichens, fungi, mammals, birds, reptiles, insects, worms, microbes
Abiotic Factors by Type
The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.
Biotic Factors by Function
Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.
These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.
These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.
Abiotic Factors by Function
The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).
Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.
A population of snails has phenotypes that range from tan to dark brown.
B)
An asexually reproducing single celled organism produces 10 offspring in its lifetime.
C)
Allele #1 for wing size in a butterfly has the following sequence of bases: GGAT, while Allele #2 has this sequence: GGAC.
Answer:
Those three are extremely related.Humus is the organic matter that forms in the soil when plant and animal matter decays. It is basicaly the part where the soil is more moistured and receives more nutrients. microoroganisms are present in the matter of plants and anumals and they are very important for the sustainability of the soil. Humus contains many useful nutrients for healthy soil, like nitrogen, which assures the proper health of it.
