Which action may increase the flask’s carrying capacity for rotifers?
A. decrease the number of microorganisms
b. introduce water fleas
c. decrease the size of the flask
d increase the number of microorganisms
Answers
The action that may increase the flask's carrying capacity for rotifers would be to decrease the number of microorganisms in the flask.
Carrying capacityThe carrying capacity of an environment refers to the maximum number of organisms of a particular species that the environment can support based on the resources it has.
Rotifers and microbes growing in the flask mean that both species would have to compete for the resources present in the flask. This competition will limit the reproductive capacity of each species.
As the population of the species decreases, the growth of the other is favored due to less competition.
With rotifers growing alone in the flask, there would be less competition for resources and more population growth.

The traditional view of mangrove forests as wastelands and unhealthy environments helped promote their degradation because people did not feel it was necessary to preserve them.
What are mangrove forests?Mangrove forest are forest of plants and trees that grows in coastal areas or back water.
These forests grow in an area where there is low oxygen, soil is present.
They are very important plants for the environment.

Answers
Answer:
There is no correlation/connection between number of chromosomes and complexity of an organism.
Explanation:
If the number of chromosomes determined the complexity of an organism, we could say that the kiwi in this problem is more complex than the human, however, this is not true. A chromosome is like a container for the genetic material (genes) of an organism, it doesn't matter how many containers there are, but rather what's inside the containers that determine genotype and phenotype.
Answer:
Not much.
Explanation:
Considering the fact that banannas have like half of the chromosomes that a living animal has, and the fact that an animal somehow has more chromosomes than a human, leads me to believe there is little to no correlation with the amount of chromosomes someone has and their complexity.

The data indicate the populations of mammals in the Florida Everglades in different years over the past two decades. The Burmese python, a non-native species, was introduced to Florida as an exotic pet. After Hurricane Andrew hit Florida in 1992, many pet owners lost track of their non-native snakes. The biodiversity of the Everglades has decreased since then. According to the data, what hypothesis is best supported with regard to Burmese pythons and Florida Everglade biodiversity?
Answers
Answer:
The correct hypothesis would be - C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Explanation:
Burmese pythons are the invasive species in this new region as they originally found in South Africa, and also one of the largest snakes so they lack natural predators in this new setting or region.
These snakes depend on both types of food which means they are omnivorous and eat both herbivore and carnivores prey.
Thus, the correct answer is - Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.

C. Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades

A. Reactants come out of a reaction.
B. Energy is always released.
C. Bonds between atoms break and reform.
D. Products go into a reaction.
Answers
Answer:
C). Bonds between atoms break and reform.
Explanation:
A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, option C is the correct answer.
Which of the following best describes homeostasis? the state of maintaining a stable internal environment despite changing external conditions the state of maintaining a stable internal environment due to electrical impulses the state of maintaining a stable internal environment due to chemical signals the state of maintaining a stable internal environment when the external conditions are constant
Answers
Answer:
the state of maintaining a stable internal environment despite changing external conditions
Explanation:
homeostasis is all about regulating, whether it be regulating body temperature through shivering, regulating body water levels, etc..
The best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions." Homeostasis is a vital physiological process that helps to maintain the internal environment of an organism.
What is homeostasis?To achieve homeostasis, the body uses various physiological and biochemical mechanisms to monitor and respond to changes in the external environment. For example, if the external temperature becomes too high, the body will respond by sweating to cool down and maintain a stable internal temperature. Similarly, if the blood pH becomes too acidic, the body will respond by increasing the excretion of hydrogen ions to restore a more neutral pH.
Hence, the best description of homeostasis is "the state of maintaining a stable internal environment despite changing external conditions."

Answers
Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
What do you mean by actin filaments?It is microfilaments that are responsible for cell shape and cellular movements.
The calcium ions are released when there is depolarization of the sarcomere occurs. They then bind to troponin and restructure the complex that is exposing the binding sites to the myosin head.
The cellular importance of the motor proteins is ATP-dependent which forces the impulse to actin filaments, and then the myosin head detaches from the old binding sites of actin.
Therefore, Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
