Answer:
Antibiotic resistance is when pathogens such as bacteria or fungi develop a resistance to antibiotics. This happens when some pathogens die, and others survive. The small number of pathogens that had a resistance to the antibiotic will reproduce more offspring that are also resistant to, and those offspring will reproduce even more offspring and so on. Eventually most pathogens will be resistant to the antibiotic, so antibiotics won't work.

symbiosis and species interactions keystone webquest answer key
These exchanges are frequently brief. However, there are many instances where two species coexist peacefully for extended periods of time.
What is keystone species?The most numerous species in a community are known as dominant species, and they have a significant impact on the abundance and distribution of other species.
Keystone species, on the other hand, have an impact on communities that greatly outweigh their abundance.
These discussions are typically can be done in many way. Two species can, however, frequently cohabit happily for long periods of time.
Such relationships are known as symbioses ("living together"). Symbiotic relationships can be classified as parasitic, commensal, or mutualistic.
Thus, this can be symbiosis and species interactions.

What is the effect of changing the environment on the feeding of birds with different beaks?
The exact traits of each bird's beak and the type of environmental alteration will determine how changing the environment will affect how various beaked birds eat.
For instance, birds with long, narrow beaks designed for digging deeply into blossoms or grabbing insects may have a tougher difficulty locating food if the environment gets drier and food sources become limited.
Their population might decrease as a result of this. Similarly to this, birds with short, broad beaks that are evolved to split apart seeds may have a tougher difficulty locating food if the environment becomes wetter and food sources become limited.
On the other hand, if the environment changes in a way that creates new food sources, birds with beaks adapted to exploit those resources may do well. For example, if a new type of berry becomes available, birds with beaks adapted for eating berries may thrive in that environment.

Plz help! In a density-dependent population, a decrease in which of the following will most likely cause an increase in birthrate?
Carrying capacity
Death rate
Emigration
Immigration
plz don't put link or ill report
In a density-dependent population, a decrease in the death rate will most likely cause an increase in birthrate. It is because a lower death rate means that more individuals are surviving, which can lead to an increase in the number of individuals reproducing, ultimately resulting in a higher birthrate. The correct option is B.
What is a density-dependent population?As we know that a population's birthrate tends to increase if there is a decrease in death rate, which also results in a decrease in carrying capacity.
Also, a density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. So, a decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.
A density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. A decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.
Therefore, the correct option is B.

The stomach is the only part of the alimentary canal with three muscular layers. Why does the stomach need three layers of muscle
The stomach is the only part of the alimentary canal with three muscular layers. The stomach need three layers of muscle for digestion through peristalsis.
The stomach is a part of the body that includes the entire abdominal cavity which consists of the digestive tract and accessory organs, the urinary system, and the spleen. There are three layers of muscles in the stomach, namely the outer longitudinal muscles, the middle circular muscles, and the inner oblique muscles which help in peristaltic events.
Peristalsis is a movement in the form of muscle contractions in the digestive tract that pushes and stirs food so that it is digested. Through peristalsis the stomach will break down food and absorb nutrients during the digestive process.
