Explanation:
Species
kingdom is further split into phylum or division, class, order, family, genus, and species, which is the smallest group.
The science of classifying organisms is called taxonomy and the groups making up the classification hierarchy are called taxa.
In the 1860s Gregor Mendel performed numerous dihybrid crosses between pea plants. Dihybrid crosses involve the study of the inheritance patterns related to two different traits. In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BbFf x bbff cross would be expected to be heterozygous for both traits
Answer:
25% of the progeny is expected to be dihybrid, BbFf, expressing Black and short fur

5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
Answer:
C. Sperm would not be able to develop properly.
Explanation:
There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.
If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.
What is the function of "sc-rotum"?A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.
Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.
Thus, the correct answer is option C.

Tongue rolling is a dominant trait. Explain why it is possible for both parents being able to roll their tongue but their biological child is not able to do so.
Answer:
The answer is 0 ( AKA A )
Explanation:
Parents form the same type of gene, which is Rr. Since all the genes are the same, there can not be a chance that the offspring can not roll the tongue. Next time focus on your work!! :3

Cells of the skeletal system are specialized in their structure to store minerals. Which of the following is the function of these cells?
Produce chemicals that transmit signals.
Prevent the spread of disease in the organism.
Provide support to the body.
Absorb excess water released by digestion.
Answer: Provide support to the body.
Explanation:
The skeletal system is a system which is formed by the bones. The bones are important for the structure and function of the body. The bones are connected with the muscles to allow the movement of the body, and they protect the vital organs like heart, lungs, brains, and others. They provide support to the soft tissues, organs, and muscles of the body. They keep the human body upright. The skeletal system provide shape to the body. It provides support by acting as regions of attachment of soft body parts and muscles.
What are Tectonic Plates made of and what do they do?
Answer:
They move
Explanation:
Answer:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.

Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to cross individuals from each of these species what would you expect to see in the hybrid offspring if behaviors related to pair-bond formation were completely due to genetics?
Answer:
I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.
Explanation:
The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.
Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.

15. Cells found in plants and animals have similarities but can differ in function. Consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.
The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.
Explanation to the difference in the cellular vacuole size:When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.
hence, the correct option is d.

explain how carbon atoms can move to co2 in the air into an organic molecule inside a plant and then back to co2 in the air
Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.
