A population of western skinks, a type of lizard, lives in a grassland habitat along the base of a mountain range. The construct

ion of a multi-lane highway will divide the habitat into two separate regions. How will the construction of the highway most likely affect the western skink population?
A. The western skink population size would decrease by half, reducing the probability that the population will evolve and speciate.

B. Western skinks would become an invasive species in one of the two regions, so the total population size would increase.

C. Western skinks would become better able to find unrelated mates, decreasing the population's susceptibility to diseases.

D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.

Answer:

Option D

Explanation:

This case of western skink is an example of geographical isolation which reduces the gene pool and hence the genetic diversity.

The entire population of western skink gets divided into two sub population. Now these two sub-populations start living in two different geographic entities due to which they evolve differently and after a long course of period if  species from these two sub population are brought closer for mating then there shall be no mating due to variation in mating preferences.

Hence, option D is correct

Answer:

The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.

It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.

The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.

The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.

Consequently, the genetic diversity would also decrease.

What kind of lab equipment would you use to conduct a small chemical experiment
Alexandra [31]

Answer:

Beaker - A beaker is a glass container with a flat bottom and a small spout for pouring. It is used in the chemistry lab for mixing, heating, and stirring liquids. Beakers come in various sizes and are shaped like a cylinder.  

Chemistry lab beakers Beakers

Bunsen burner - The Bunsen burner is a metal tube that produces a flame from gas such as methane, propane, or butane. It is used in the lab for heating and sterilizing. The Bunsen burner is named after German chemist Robert Bunsen.  

Bunsen burner

Crucible - Crucibles are containers used for heating substances to very high temperatures. They are generally made from materials such as porcelain, nickel, and alumina.  

Erlenmeyer flask - This is a type of chemistry flask with a conical shaped body, a cylindrically shaped neck, and a flat bottom. It generally has measurement marks on the side. It is similar to a beaker, but has the cone shaped body. The cone shape reduces losses from evaporation and helps to prevent spills when stirring the liquid.  

Erlenmeyer flask

Funnel - A funnel is a pipe with a wide mouth that helps to pour substances into a container without spilling. In a chemistry lab, funnels are often used together with filters to separate a mixture.  

Funnel and flask

Gloves - Laboratory gloves are important to wear in order to protect the skin from chemical substances. Always listen to your teacher and make sure to wear gloves when performing experiments.  

Always wear gloves

Goggles - Goggles are very important when performing experiments of any kind. They can keep dangerous chemicals and other substances from damaging your eyes. Always wear your goggles in the lab!

Always wear goggles

Graduated cylinder - A tall skinny cylinder used to measure volumes. It is generally a more accurate way to measure volume than a typical beaker or flask.  

Graduated cylinder

Mortar and pestle - A mortar and pestle are used to crush and grind solids into a powder. The mortar is a bowl and the pestle is a small club-shaped tool. They are typically made from ceramic or stone.  

Mortar and pestle

Pipette - A narrow glass tube used to transfer liquids from one place to another. Pipettes sometimes are used for measurement. The accuracy of different pipettes varies widely.  

Pipette

Scoopula - A scoopula is a metal spatula-type utensil used to scoop up solids such as powders in a chemistry lab.  

Stirring rod - A skinny solid glass rod used in chemistry to mix chemicals and liquids. A stirring rod is typically about the length of a long straw and has rounded ends.  

Test tube - A test tube is a glass or plastic tube used for holding, mixing, and heating small quantities of liquid chemicals. Test tubes often have a flared top to help with pouring. They come in a variety of sizes.  

Test tube holder - A stand built for holding multiple test tubes.  

Test tube brush - A brush designed to help clean out test tubes.  

Test tube clamps - Clamps that hold test tubes while using them to heat up chemicals during a lab experiment.  

Test tubes in a holder

Thermometer - A device used for measuring the temperature of a substance.  

Triangle - A triangle made of clay pipes and wire that can withstand high temperatures. It is often used to hold a crucible.  

Wire gauze - A wire gauze is used to support a beaker or flask when heating. The wire gauze helps to spread the heat evenly.

gtnhenbr [62]

<u>Answer:</u>

The correct answer is Uracil which is nitrogen base found in RNA.

<u>Explanation:</u>

Uracil is a nitrogenous base which is located within an RNA molecule but not within a DNA molecule.

Uracil, represented by the letters A, G, C and U, is one of the four nucleobases that are found in the nucleic acid of RNA which binds to adenine.

While thymine is present in the DNA and binds to adenine.
