What is the difference between learned behavior and an inherited behavior?
Answer:
Learned behavior is a trait that something learned to do, like how to read or ride a bike. Inherited behavior is instictual and naturally comes to an organism at birth, like sleeping or eating.
Which type of reproductive isolation occurs when there are differences in the size or shape of reproductive parts and may prevent interbreeding
Temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.
A prezygotic barrier called temporal isolation promotes speciation, or the creation of new species. Isolation on account of geography, reproduction, or behavior are other prezygotic obstacles.
What reproductive isolation occurs in temporal isolation?A reproductive isolation process known as temporal isolation prevents members of closely related species from mating and producing hybrid offspring.
Temporal isolation occurs when essential reproductive activities occur at different times in sexual organisms.
When two or more species reproduce at different times, this is known as temporal isolation. For instance, three different orchid species might be found in the same rain forest.
Therefore, Each species possesses one-day-only blooms that need to be pollinated on that day in order to produce seeds.

. To calculate the probability that an individual taken at random from a population has a particular genotype (AA, Aa, aa), biologists usually think in terms of a pool containing all the alleles from all the parents, known as the gene pool. This is particularly useful when it is impossible to keep track of ancestry (otherwise known as a pedigree).

California condors (Gymnogyps californianus) are listed on the IUCN Red List as being critically endangered. Since 2003, the California Condor Recovery Program has been reporting their demographic data. In 2012 they estimated the number of individuals living in the wild to be 235. If their intrinsic rate of natural increase is 0.089 ind/year, predict the size of the California condor population in 2022.
Answer:
≈ 572
Explanation:
Predict the size of the California condor in 2022
we can predict this value with this relation below
Nt = No*e^(rt) --- ( 1 )
where ; Nt = Future population , No = initial population, r = intrinsic rate of increase , t = time
No = 235
r = 0.089
t = 2022 - 2012 = 10
Insert values into equation 1
Nt = 235 * e^( 0.089 * 10 )
= 235 * e^0.89
≈ 572
Therefore the size of the California condor population in 2022 ≈ 572

Explanation:
Effector molecule binding changes the behavior of enzymes by altering the equilibrium between the tense (T) state and the relaxed (R) state. Effectors are classified as either homotropic or heterotropic. Match each description with homotropic effectors, heterotropic effectors, or both. Some statements may not describe either type of effector.
Homotropic effector Heterotropic effector Both an enzyme's substrate alters the K of an enzyme works by altering the T/R ratio accounts for the sigmoidal nature of a velocity versus substrate concentration curve alters the V. of an enzyme
Answer:
Explanation:
Homotropic effector-[tex]\text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}[/tex][tex]\text{An enzyme's substrate.}[/tex]Both -[tex]\text{Works by altering T/R ratio.}[/tex]The phrase [tex]\text{"accounts for the sigmoidal nature of a velocity versus }[/tex]
is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.
The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.
The phrase [tex]\text{"works by altering the T/R ratio"}[/tex] is significant and can be applied for both homotropic and heterotropic effectors.
The expression [tex]\text{"an enzyme's substrate"}[/tex] is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.
The phrase [tex]\text{"alters the} \ K_m \ \text{ of an enzyme"}[/tex] is not applied and insignificant to none of the heterotropic or homotropic effector molecules since [tex]K_m[/tex] is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain

Select which option correctly Identifies if the following cross section of a stem is a monocot or a dicot and explains the correct reason why.
A. dicot because the vascular bundles are arranged randomly
B. monocot because the vascular bundles are arranged randomly
C. monocot because the vascular bundles are arranged in a pattern
D. dicot because the vascular bundles are arranged in a pattern
Answer: The following cross section of a stem is a monocot because the vascular bundles are arranged randomly. Correct option is B.
Explanation:
The flowering plants form the largest group in the plant kingdom. They are more highly evolved than gymnosperms because they have an abundance of water and food conducting vessels known as the VASCULAR BUNDLES..
The angiosperms are grouped into two namely:
---> Dicotyledons and
--> MONOCOTYLEDONS: These are the most advanced plants. They tend to be more efficient and specialised because they have fewer parts. As such they show a very high degree of adaptation to their environment. The VASCULAR BUNDLES which is defined as the conducting vessels (transport system) made up of xylem and phloem, are arranged randomly. The xylem is the water conducting tissue which also had a strengthening function while the phloem is the transports organic molecules ( food). The vascular bundles are scattered because they lack cambium and therefore do no undergo secondary growth.

oxidative phosphorylation
Answer:
D
Explanation:
When performing low-intensity activities, the oxidative system uses fats as a substrate to produce ATP. Thus, option D is correct.
What is the significance of oxidative phosphorylation?The majority of the ATP required for higher animals and plants to sustain life is produced by oxidative phosphorylation, which is also in charge of establishing and preserving metabolic equilibrium.
The last phase of aerobic cellular respiration is oxidative phosphorylation. The production of many ATP molecules is the primary goal of oxidative phosphorylation.
The energy system that largely supports prolonged, low-intensity exercise is sometimes referred to as the aerobic system. By boosting oxygen availability and enhancing our capacity to metabolize fat for energy, it supports this kind of exercise.
Therefore, oxidative phosphorylation take place in mitochondria.
