Biology
1 answer:
qaws [65]2 years ago
4 0

Answer:

dam building, heavy industry, deforestation, irrigation, agriculture, infrastructure, construction, burning fossil fuels, mining, fishing, there is a few that is what I came up with for the ecosystems, and for the food chains and food webs hunting. Hunting interferes with the food chain because the predators are not getting what they want because humans are hunting.

Of glucose produces glycogen, the storage form of sugar, found in the liver and muscles
7nadin3 [17]

Glycogen is a homopolysaccharide formed by units of glucose and is sometimes referred  to as animal starch. It can reach up to a molecular weight of 10 to the power 8  DA which corresponds to about 600,000 glucose molecules.

 The function of glycogen is that it is the principal form in which glucose is stored in animals and is present in the liver, muscle (skeletal and heart muscle) and in lower amounts in nearly all the other tissues and organs.

Glycogen makes up about 10% of liver weight and 1% of muscle weight. Although it is present in higher a concentration in the liver, the total amount stored in muscles is much higher due the greater mass of the muscles as compared to the liver.

Why is it more common to find short food chains than long food chains?
zimovet [89]
Because a food chain is based on one certain thing in the ecosystem ....if the entire ecosystem was in it it would be a food web which is food chains from an ecosystem linked together

Hope that helps

Wolves, which are top predators, were eliminated from Yellowstone National Park in the 1930s. In 1995, wolves were reintroduced
KIM [24]
The population of their prey most likely increased causing an imbalance in the food chain. This is true since there probably was not enough food to feed the rapidly increasing population.

Which conditions are common to all three of the following: genetic drift, the founder principle, and the bottleneck effect? a. i
Tcecarenko [31]

Explanation:

Common to genetic drift, the founder principle, and the bottleneck effect:

b. in small populations and result in a decrease in genetic diversity and/or an increase in the occurrence of specific genetic traits

c. when a small group of organisms only reproduce with each other to create a larger population of organisms

d. when the majority of a population is killed off and there are only a few remaining organisms left to rebuild the population

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species.

  • mutations accumulate in a population over time, altering the frequency of alleles or different forms of a gene- this is called genetic drift.
  • In the founder effect, the separation of a group from a larger group can decrease genetic diversity, this can create a genetically distinct population
  • In the bottleneck effect, a population die off or barrier to reproduction increases the genetic drift in the population
