Answer:
A control in an experiment is a replica used to confirm that the results or changes in the dependent variable/s are caused by the independent variable values or treatments. There are different kinds of controls according to the experiment, for example, no treatment can be applied, or for example in laboratory experiments, there are controls to check that the reactives function properly, making a replica with them but without the sample that is being measured.

Which organism exhibits behavioral adaptation?
A- An owl with large pupils and eyes that enable it to see better at night
B- A possum playing dead to increase its chances of survival
C- An insect that mimics its environment to hide from its predators
D- A desert plant that sheds its leaves to lessen water loss during the dry season
This is form the Edge Biology test btw
A possum playing dead to increase its chances of survival organism exhibits behavioral adaptation. Correct Option is 2.
Behavioral adaptations refer to the actions or responses exhibited by organisms in response to their environment or specific stimuli to improve their chances of survival and reproduction. Among the options provided, choice B, a possum playing dead to increase its chances of survival, best represents a behavioral adaptation.
When a possum plays dead (a behavior known as "playing possum" or "playing dead"), it is exhibiting a defensive response to threats or predators. When confronted by a potential predator, a possum will feign death, becoming limp and unresponsive. This behavior can deceive predators into thinking that the possum is no longer a threat or potential prey, giving the possum a chance to escape from danger.

bulbils are means of vegetative propogation?
Answer:
vegetative propagation by bulbils-;they are flesh eating Birds which are produced in the axils of leaves in place of axillary but these bulbils give rise to new plants when they fall on ground
More basic information :regeneration of new plant from the vegetative part of organ of the parent plant is called vegetative reproduction and propagation
vegetative reproduction and vegetative propagation is useful to spread the plant in wider region one some other plant get favourable condition it is then colonized to that reason of vegetative propagation

The most likely reason there are no colonies in cultures of this species at PH 4 and at Ph 10 is that
The most likely reason there are no colonies in cultures of this species at pH 4 and at pH 10 is that the species needs neutral pH to survive, not surviving at acidic or basic pH.
How are bacteria classified according to pH?Regarding pH tolerance, bacteria can be classified into three categories:
neutrophilsacidophilesand alkalinophiles.What is the neutral pH value?pH is the unit of measurement that describes this degree of acidity or alkalinity, measured on a scale of 0 to 14. Any pH below 7 is considered acidic and any pH above 7 is considered basic, or alkaline. A pH of 7 is neutral, which is neither acidic nor basic.
With this information, we can conclude that The most likely reason there are no colonies in cultures of this species at pH 4 and at pH 10 is that the species needs neutral pH to survive, not surviving at acidic or basic pH.

What does the sequence of amino acids tell you about an organism and its relationship to another?
Would they be similar or different? Why?
Answer: Because the amino acid sequence of a protein is determined by its DNA sequence, a gene shared by two closely related animals should have amino acid sequences that are similar, if not identical. Because closely related species split from one another very recently in the evolutionary timeline, this is the case.

called what? a. species separation b. genetic mutation c. genetic resistance d. naturalselection
According to the research, population members that are more likely to survive and reproduce is a principle called natural selection.
What is natural selection?It is the process of adaptation to the environment by which only living beings with certain characteristics reproduce and survive.
Better-adapted organisms crowd out less-adapted ones by slowly accumulating favorable genetic changes in the population over generations.

Which describes a feature of the physical changes of all substances? can dissolve in water can conduct heat and electricity rearranges atoms to form new substances does not change the identity of a substance
Answer:
does not change the identity of a substance
Explanation:
when a substance undergoes a physical change, the molecules move further apart but the chemical structure of the molecule does not change
Dissolving in water can conduct heat and electricity and rearranges atoms to form new substances but does not change the identity of a substance are some examples that describe physical changes.
What are physical changes?The changes can be physical and chemical. Physical changes occur when the physical properties changes. The changes can be of many types such as changes in colour, solubility, and change in the state of matter. Change of solid state to a liquid state, liquid state- to vapour and solid state -to vapour.
Neither the chemical nature nor the composition of the matter changes during the physical change. Rearrangement of the molecules takes place during the physical change without affecting the chemical composition of the matter.

During ____________ , an enzyme removes a ____________ functional group from the monomers of one organic molecule and a hydrogen from another monomer, linking monomers together to form a ____________ . This chemical reaction also forms ____________ .
During dehydration synthesis, an enzyme removes a hydroxyl functional group from the monomers of one organic molecule and a hydrogen (H) from another monomer, linking monomers together to form a polymer. This chemical reaction also forms water molecules as byproducts.
An enzyme removes a hydroxyl (-OH) group from one monomer and a hydrogen (H) from another during dehydration synthesis, allowing the monomers to form a polymer. This mechanism bonds monomers covalently and produces water molecules. Complex biological components including proteins, nucleic acids, and carbohydrates depend on dehydration synthesis.
Eliminating water molecules strengthens chemical connections, making it easier to assemble bigger structures from smaller components. This response aids energy storage, structural stability, and information flow in living things.
