You collect individuals from different allopatric populations of a leaf-eating beetle. In the laboratory, you conduct mate-choice experiments to assess levels of reproductive isolation among beetles from different populations. Assuming that ecological speciation occurred in the wild, which pattern should you expect?.

Answers

Less reproductive isolation among populations that share similar habitats.

What is ecological speciation?

The process through which new species arise as a result of divergent natural selection between dissimilar ecological habitats is known as ecological speciation. Ecological speciation happens when reproductive isolation evolves as a result of adaptation to various habitats or resources.

The brief history of a gene flow barrier in the population that leads to environmentally based divergent selection in the development is known as ecological speciation. The Charles Darwin theory of evolution is connected to this one. It offers the world's population diversity. The species frequently occurs through natural selection. Additionally, the speciation happens in two ways:

The genetic diversity in the population does contribute to ecological speciation.

An approach that uses passive solar heating instead of electricity for businesses and homes is known as

daylighting
weatherizing
green roofing
cool roofing

Answers

An approach that uses passive solar heating instead of electricity for businesses and homes is known as A. Daylighting.

What is daylighting?

This is the illumination of buildings with natural light through the practice of placing reflective surfaces so that sunlight can provide effective internal lighting.

Solar heating is the use of sunlight to heat water or air in the buildings using radiant light and heat which is harnessed using a range of technology such as solar power to generate electricity.

Hence, we can see that neither weatherizing, green roofing nor cool roofing is the answer because they do not deal with providing passive solar heating, but daylighting uses passive solar heating.

Therefore, the correct answer is option A.

If a runner is doing vigorous exercise, which results from the anaerobic cellular process?
accumulation of lactic acid
accumulation of oxygen
depletion of ethanol
depletion of carbon dioxide

Answers

Answer:

Accumulation of lactic acid

The anaerobic cellular process is a type of respiration that occurs in the scarcity of oxygen. Lactic acid gets accumulated in anaerobic respiration during vigorous exercise. Thus, option A is correct.

What is anaerobic respiration?

Anaerobic respiration is a cellular process where the organic and the biological fuel are broken and oxidized through the electron transport chain in the cytoplasm of the cell.

The anaerobic cellular process lacks the use of oxygen so to produce energy like ATP and lactic acid accumulation due to the high energy demand during vigorous exercise.

In the anaerobic cellular process, carbon dioxide and water are formed as a byproduct along with lactic acid and ATP. Lactic acid is formed from the breakdown of glucose and glycogen.

Therefore, in option A. in the anaerobic cellular process, accumulation of lactic acid occurs.

Diabetes, a recessive trait, occurs in 10% of a certain population. What is the proper letter used as a symbol for the gene concerned? If a
normal female and a normal male in this population have a child who is diabetic, what is the probability that their next child will be a
diabetic?

Answers

Diabetes can be properly designed by using the letter symbol for the gene concerned as a lowercase letter (d) because it is a recessive trait.

What is a recessive trait?

A recessive trait is any phenotypic feature that is expressed when two recessive alleles are found in an individual and show complete dominance by means of dominant alleles that masks recessive expression.

For example, if a normal female and a normal male in the population have a child who is diabetic, then the probability that their next child will be 25% (parents are heterozygous for the trait).

In conclusion, Diabetes can be properly designed by using the letter symbol for the gene concerned as a lowercase letter (d) because it is a recessive trait.
