The population of frogs would exhibit competition due to the limited resources in the lake. Competition can be defined as the interaction among the species of organisms when resources are limited in an ecosystem. The type of competition observed in the above example of the lake with limited resources is called intraspecific competition as it is between the members of the same species competiting for the same resources. The species that do not compete will eventually die or get eliminated. This results in the change of population of frogs over time. Thus, competition is one among the forces that is responsible for natural selection.

Which of the following is an example of discrete data?
LekaFEV [45]

THE DOG HAS 2 BROTHER is the example of discrete data.

The dog has 2 brothers.

<u>Explanation:</u>

Discrete data is the information that can be categorized into a classification. Discrete data is based on counts. only a few finite number of value is possible.

It consists of whole number that are counted rather than measured. It can be classified  into two type, one is discrete and  other is continuous data, where the discrete is countable of the object and the continuous  is measurable one.

The dog has two brother is the example for discrete data because the number can be countable, remaining statement are continuous because they are measurable statement, it is always comes under the data continuous.

Many mutations have been identified in the lac operon. A particular mutation in the CRP gene make the CRP protein bind to the Pl
maksim [4K]

Answer:

a. + glucose, + lactose  = On

b. - glucose, - lactose  = Off

c. + glucose, - lactose  = Off

d. - glucose, + lactose = On

Explanation:

Lac operon has both types of control, repressible and inducible.

Whenever glucose level is low in the cell, an enzyme known as adenylyl cyclase raises the level of cAMP which forms a dimer with CRP protein and they both act as activator of lac operon and cause expression.

Apart from this, when lactose is present in the cell, β-galactosidase enzyme metabolizes lactose to form allolactose which causes allosteric repulsion in the lac repressor and causes its removal from the operator. As soon as repressor is removed lac operon gets activated.

In wild type lac operons, the expression of lac operon occurs when glucose level is low in the cell and lactose is present but in this mutant presence or absence of glucose will not make a difference because CRP will bind Plac promoter independent of cAMP level i.e. activator CRP will work even in high glucose concentration. If lactose is present then lac operon will always express so in option 'a & d' lac operon will express but in option 'b & c' it will not express.

Research indicates that as levels of happiness increase, cortisol levels appear to increase as well. Please select the best answ
iogann1982 [59]

Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.

<h3>What are cortisol and its function?</h3>

Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.

It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.

It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.

Therefore, the statement is false.
