what is the difference between Resilience and Resistance in ecosystem?
Answer: Rate and Abiltiy
Explanation: Resistance is the ability for an ecosystem to remain unchanged when being subjected to disturbance or disturbances. Resilience is the ability and rate of an ecosystem to recover from a disturbance and return to its pre-disturbed state.
Resistance is an ecosystem's ability to withstand disruptions. Resilience is an ecosystem's ability and rate to recover from disturbances.
What is Resilience and Resistance in ecosystem?Because of a population's resistance or resilience, it may be possible for that population to survive a disturbance. In general, the capacity of a population (or community) to tolerate the disturbance is referred to as its resistance, while the capacity to recover after being affected by the disturbance is referred to as its resilience.
Resilient ecosystems contribute to social and economic well-being by providing a solid base for different sectors (fishing, recreation, and tourism) and reliable ecosystem services that improve quality of life. Resistant ecosystems can keep their structure, processes, and functioning when stressed or invaded.

1. Describe cell differentiation and include any environmental factors that play a role in gene regulation. 2. Explain the types of cells produced by meiosis. Include in your explanation the number of daughter cells produced, the number of chromosomes in each and whether they are diploid or haploid.
Answer:
1. Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens.
2. Gametes or sex cells are produced in meiosis and they have haploid number of chromosomes. In humans, the haploid number of chromosomes is 23 chromosomes.
Explanation:
Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. During the initiation of cell differentiation, transcription factors activate only the genes to be expressed. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, and the presence of mutagens(factors that cause mutation).
Differentiation occurs in zygotes numerous times resulting in the formation of a fully developed organism. Also in unspecialized cells known as stem cells, differentiation occurs leading to the formation of various cells of the organs and tissues of the body.
2. Meiosis is a type of cell division in which gametes or sex cells are produced. A single cell divides twice producing daughter cells with half the number of chromosomes present in the parent cell. In humans, the chromosome number is 46. After, meiosis, the haploid number of chromosomes produced is 23.

How does competition shape communities?
Answer:
In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.
Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.
In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.
Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.

What is cell?In biology, a cell is indeed a primary membrane-bound unit that includes the essential components of life and is made up of which all living organisms are made. A single cell, like a bacterium or yeast, is frequently a full organism in and of itself. As cells age, they develop specific roles.
These cells collaborate with some other specialized cells to form the foundation of huge multicellular creatures like animals and humans. Micrographs reveal a tangle of cells plus internal components that are difficult to detect separately.

Which inheritance pattern results when parents with pure traits are crossed and the resulting offspring have traits that appear to be a blend of the parents' traits?
incomplete dominance
codominance
Mendelian inheritance
polygenic inheritance
Answer:
incomplete dominance
Explanation:
pure traits are crossed and the resulting offspring have traits that appear to be a blend of the parents traits
The inheritance pattern that results when parents with pure traits are crossed and the resulting offspring have traits that appear to be a blend of the parents' traits is incomplete dominance.
What is incomplete dominance?Incomplete dominance is the situation where the phenotype of the heterozygous phenotype is distinct from and often intermediate to the phenotypes of the homozygous phenotypes.
This means that in when a allele is incompletely dominant over another allele, an intermediary phenotype is produced.
This phenotype is a blend of both parental phenotypes. Therefore, the parents trait are said to be incompletely dominant.

A human eats a meal and afterward their blood glucose levels rise. Explain how the human body responds to return their blood glucose level to normal.
Answer:
Explanation:
The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.
Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).
Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal
