There's two ecosystems. A Terrestrial Ecosystem and an Aquatic Ecosystem. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts. Wetlands, rivers, lakes, and coastal estuaries are all aquatic ecosystems.

Explanation:
how can you explain what you know about the heavily muscled cows with what you have learned about mutations, patterns of inheritance, incomplete dominance, sexaul reproduction, selective breeding and transferring of genetic information?
Myostatin (GDF-8) is a member of the transforming growth factor β superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass in mice. Here we report the myostatin sequences of nine other vertebrate species and the identification of mutations in the coding sequence of bovine myostatin in two breeds of double-muscled cattle, Belgian Blue and Piedmontese, which are known to have an increase in muscle mass relative to conventional cattle. The Belgian Blue myostatin sequence contains an 11-nucleotide deletion in the third exon which causes a frameshift that eliminates virtually all of the mature, active region of the molecule. The Piedmontese myostatin sequence contains a missense mutation in exon 3, resulting in a substitution of tyrosine for an invariant cysteine in the mature region of the protein. The similarity in phenotypes of double-muscled cattle and myostatin null mice suggests that myostatin performs the same biological function in these two species and is a potentially useful target for genetic manipulation in other farm animals.
The transforming growth factor β superfamily encompasses a large group of secreted growth and differentiation factors that play important roles in regulating development and tissue homeostasis (1). We have recently described a member of this family, myostatin, that is expressed specifically in developing and adult skeletal muscle and functions as a negative regulator of skeletal muscle mass in mice (2). Myostatin null mice generated by gene targeting show a dramatic and widespread increase in skeletal muscle mass. Individual muscles in myostatin null mice weigh 2- to 3-fold more than those of wild-type mice, primarily due to an increased number of muscle fibers without a corresponding increase in the amount of fat. To pursue potential therapeutic and agricultural applications of increasing muscle mass by inhibition of myostatin activity, we have been characterizing myostatin in animals other than mice. Here we report that the myostatin gene is highly conserved among vertebrate species and that two breeds of cattle that are characterized by increased muscle mass (double muscling), Belgian Blue (3) and Piedmontese (4), have mutations in the myostatin coding sequence. These results demonstrate that the function of myostatin has been highly conserved among vertebrates. hope it helps
Which type of succession (primary or secondary) is going to have the biggest impact on an ecosystem?
Answer:
Secondary succesion because secondary succession follows a major disturbance, such as a fire or a flood.

Reflect again on competitive relationships. What would happen if the factor became more abundant or unrestricted?
Answer:
If a factor became more abundant, there would still be competition, but there would be less. *See below for an explanation that makes a little more sense (No, I am not sending you a link)*
Explanation:
In every ecosystem, there is competition. The competition could be for mates, food, shelter... anything, really. However, when those resources become more prevalent, there still might be competition, but there would probably be less than before. Let's try an example: Imagine that we were about to endure an incredibly strong hurricane. If you have ever prepared for a hurricane, you would most likely understand that if you get to the stores too late, there most likely wouldn't be much to choose from. Everything would be cleared from the shelves. Now there is competition for resources such as food and water that we would need to spend several days without power and electricity. However, if the shelves were to restock and everything is replenished, there wouldn't need to be any fighting over toilet paper, right? The same happens with plants and animals. If there is a sudden abundance of resources, they no longer need to compete so aggressively. *You might also see an increase in population, too*
Sorry, I gave such a wordy answer. I just really, really, really want you to understand so you good grades. I hope you understand :) :) :)
If the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.
What is Competition?Competition may be defined as a type of species interaction that significantly affects both species negatively because both species here compete for the same resources. It is a type of negative-negative interaction.
According to the context of this question, if a factor or resource remarkably increases its abundant and became unrestricted, it will definitely lead to the process that increases the competition between two or more species. This is because it allows the organisms to move away from their original niches.
Therefore, if the factor became more abundant or unrestricted, the competition will definitely increase among the organisms in the ecosystem.

Answer:
Taproot is a root system where roots develop from a single nodule.these are usually deep rooted .thus the plant gets tightly anchored to the soil. Fiberous root is a system where first a single root develops and further roots develop from it.these are not deep rooted and the plant is not properly anchored to the soil
