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.

How does artificial selection cause rapid changes in the phenotypes of organisms?
A.By selecting dominant genotypes
B.By changing the number of
chromosomes
C.By changing the frequency of alleles and
selecting new combinations of traits
D.By stimulating the species to increase
the production of new mutants
Answer: A. By selecting dominant genotypes
Explanation:
Artificial selection or selective breeding can be defined as the induced breeding process in which humans select parents of plants and animals that have desired traits that are beneficial for them to produce offspring that have characteristics of both parents and they are of improved yield and quality. This brings the change in the phenotypes of the offspring as compared to the parents. As the passage of dominant desirable traits in the genotype from either of the parent when gets expressed then the phenotype of the organism also change.

A heterozygous female with long whiskers mates with a heterozygous male with long
whiskers... W=long whiskers w=short whiskers
What is the PHENOTYPIC RATIO of the offsprings?
Answer:
3 long whiskers: 1 short whiskers
Explanation:
This question involves a single gene coding for whiskers length in a certain animal. The allele for long whiskers (W) is dominant over the allele for short whiskers (w). This means that a heterozygous individual (Ww) will possess a long whisker.
According to this question, a heterozygous female with long whiskers (Ww) mates with a heterozygous male with long whiskers (Ww). The proportion of offsprings that will be produced from this cross (see punnet square) is as follows:
WW, Ww, Ww, ww
WW, Ww, Ww offsprings will possess a long whisker while 'ww' offspring will possess a short whisker. Hence, the phenotypic ratio will be 3 long whiskers: 1 short whiskers
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

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.

A number of studies are carried out in order to verify if there is a relation between the death rate by cardiac diseases ánd the cholesterol level in the blood.The results are shoen in the adjacent graph..
1) explain the relation between the level of blood cholesterol and the risk of cardiac accident
2) firmulate the hypothesis tested in this study
3) what do you conclude concerning the formulated hypothesis?
Answer:
The correct answer is :
1. increase in cholesterol level leads to more death due to cardiac disease.
2. Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"
3. Everyone should limit or control their cholesterol level to avoid cardiac disease or it might be lethal.
Explanation:
In this graph, it is represented that there is an increase in the deaths due to cardiac disease with the increase in the cholesterol in the body. The death increase slowly up to 2.5 gL and after that, there is a huge spike in death, which explains that the higher the cholesterol level higher the chances or risk of death due to cardiac disease.
Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"
On the basis of this one should control its body cholesterol to avoid the chances of cardiac disease as it may lead to death.
i. Identify an environmental problem associated with large-scale intensive agriculture on soil.
Intensive agriculture is resulting in the loss of ecosystem and is contributing to global warming.
• An agricultural mechanization and intensification system, whose main objective is to increase the productivity from the accessible land via several means like heavy use of chemical fertilizers and pesticides is known as intensive agriculture.
• The intensive agriculture is generally aimed to feed large population of humans, however, the method has contributed as one of the biggest threat to global environment, as it is resulting in the loss of ecosystem and global warming.
• It is accountable for the 80 percent of the tropical deforestation and emergence of novel parasites and reemergence of the parasites, which were under control at one time.
• The intensive farming hampers the beneficial plants and insects, and depletes and degrades the soil it relies upon.
• It is resulting in soil erosion and is resulting in the genetic erosion of the livestock species and crops around the globe.
Thus, intensive farming in order to feed large populations is eradicating the world agriculture slowly and gradually.
