Which traits would Aristotle have used to classify sharks? Choose more than one answer.
Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
The traits that Aristotle would have used to classify sharks are :
Front with points ( hornlike )Front without points Sharks classificationSharks whose front have two points like horns are classifed by Aristotle as sharks 14 (Mobulidae). whlie sharks whose front does not have two points like horns are classifiesd as sharks 9 ( Dasyatidae ). hence the traits that would have been used by Aristotle to classify sharks is the presence of points at the front.
Hence we can conclude that the traits that Aristotle would have used to classify Sharks are Front with points and front without points.

How are oxygen and carbon connected through the atmosphere, geosphere, and hydrosphere. Give an explanation of how a plant might use all three spheres
Answer:
Explanation:
To preserve Zoological garden expertise are needed to manage the creatures that are there.
Good and conducive environment should be provided for the animals.
Routine cleaning to avoid outback of diseases
Adequate resources should be provided this include food to avoid eviction of important species.
Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.
Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide
Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.
Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.
Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.

Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

How do the data that Samantha obtained help explain the way that the body maintains homeostasis during exercise? Include the activities of at least three body systems in your explanation.
Answer:
the way that the body maintains homeostasis during exercise is the removal waste product such as carbon dioxide gas which is produced during cellular respiration.
Explanation:
During exercise, the body needs more oxygen and nutrients. For this purpose, energy is released in the process of cellular respiration. The product of cellular respiration the generation of energy in the form of ATP and carbon dioxide gas. ATP is used by the body while carbon dioxide is removed from the body during breathing. During exercise, the glucose is provided by the digestive system to the mitochondria of the cell and the waste product is removed through respiratory system of the body while the circulatory system sends energy molecules where it is needed in the body and carbon-dioxide to respiratory system for removal.

Post- pedigree questions: If you were Ketih and Marsha's genetic counselor, what would you tell them? _____________________________________________________________________________________ Which of the Jackson's grandchildren are definitely carriers? _____________________________________________________________________________________ What is Adrienne's genotype? ________________________________
Answer:
Answer to Question 1:
Sickle cell anemia is a recessive disorder. The fact that one of their children is a carrier means that either of Keith and Marsha is a carrier ot it might be that both of them are carriers of the disease.
Answer to Question 2:
The other two kids of Jeff and Adrienne who don't have the genetic disease are still carriers of sickle cell anemia.
Answer to Question 3:
Adrienne is a carrier of the sickle cell anemia disease as well, just like Jeff.

Which characteristic makes fungi similar to plants?
Answer:
They are both non-mobile and eukaryotic.
Explanation:
Plants and fungi both remain stationary. They do not move around for their food. Another similarity is that they both are made up of eukaryotic cells, meaning they contain a nucleus.
Answer:
While both are eukaryotic (both have nucleus) and don't move, plants are autotrophic, making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic, taking in food for energy (so they eat dead and decaying food), and have cell walls.

A model of a gene, DNA, and a chromosome is shown here. A researcher tags the gene with a heavy radioactive isotope (P-32). Which statement predicts the outcome of the radiolabeling on the gene, DNA, and chromosome while differentiating between the three components of the model?
Answer:
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes
Explanation:
Genes are made of DNA, but there are many (numerous) genes found along chromosomes. Only a small portion of the chromosome will be radiolabeled.
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
What is the relationship among DNA a gene and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Thus, The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
