B) Shows comparative homologous structures among different species.

The answer is B. This because the pictures shows structures of different species (this can be found in the captions) which can be compared . . . or in this case, comparative.

Therefore, the answer you're looking for is B) Shows comparative homologous structures among different species.

<em>I hope this helped!</em>

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.

The row of energy in a grassland ecosystem is shown
bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

The inability of organisms to evolve anything that could be an advantage reflects _____.
sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

ALL animals make use of other animals and organisms for food. They are heterotrophic so they have to get energy elsewhere.

ALL animals are capable of motion at some stage of their lives.

Animals developed specialized cells and tissues that are advanced and complex.

And because all animals eat I would assume they all digest the food they ingest. Other than parasites who don't really digest their food.
