The type of physical environment in which a species typically lives is its _______.
- a. niche
- b. habitat
- c. community
- d. population

Introduction: The branch of science that deals with the study of the relations among organisms and their physical environment. A group of species that lives in the same geographical place at a specific time is known as community.
Answer to Problem 1SQ
Correct answer: The type of physical environment in which a species typically lives is its habitat.
Hence, the correct answer is option b.
Explanation of Solution
Reason for the correct answer:
The place or the environment in which all the species naturally live and consists of all the biological and physical features that are accessible to a species is known as habitat. All the species living in a specific habitat comprises a community.
Option b. is given as “habitat”.
The place or the environment in which all the species naturally live is known as habitat.
Hence, the correct answer is option b.
Reason for the incorrect answer:
Option a. is given as “niche”.
The role played by the species in order to meet their needs in its community is known as ecological niche. Niche is not the physical environment in which the species lives naturally.
Hence, option a. is incorrect.
Option c. is given as “community”.
A group of species that lives in the same geographical place at a specific time is known as community. All the species living in a specific habitat comprises a community. The community is not the type of physical environment in which the species lives naturally.
Hence, option c. is incorrect.
Option d. is given as “population”.
The number of organisms that live together in the same area is called population. Population is not the physical environment in which the species lives naturally.
Hence, option d. is incorrect.
Therefore, options a., c., and d. are incorrect.
The habitat is a type of physical environment in which the species lives naturally.

- Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group?

- Molecular Biology Question. Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forwardUsing the data provided on the mean body mass and horn size of 4-year-old male sheep, draw a scatterplot graph to examine how body mass and horn size changed over time.arrow_forwardPlease write a 500-word report about the intake of saturated fat, sodium, alcoholic beverages, or added sugar in America.
