Summary Introduction

Introduction: Animal cells secrete an extracellular matrix (ECM) that provides support and helps in the organization of cells. ECM is composed of the major macromolecules, such as proteins and polysaccharides.

Answer to Problem 1TY

Correct answer: The function of the extracellular matrix in animals is to provide structural support, strength, organize cells and other body parts, and cell signaling. Hence, the correct answer is option e.

Explanation of Solution

Reason for correct answer:

The four functions of extracellular matrix (ECM) in animals are structural support, strength, cell signaling, and cellular organization.

ECM present in the skin of mammals prevents tearing. It provides protection to the joints and internal organs. The bones and cartilage of many animals are composed of ECM. Skeleton provide structural support as well as facilitate movement. ECM attached to the cells play an important role in the proper organization of cells. Cells in multicellular organisms sense their environment through ECM.

Option e. is given as “all of the above”

The four functions of extracellular matrix (ECM) in animals are structural support, strength, cell signaling and cellular organization. Hence, the correct answer is option e.

Reasons for incorrect answer:

Option a. is given as, “to provide strength”.

ECM present in the mammals provides protection to the joints and internal organs. Moreover, it also provides structural support, and plays an important role in proper arrangement of cells and cell signaling. Hence, option a. is incorrect.

Option b. is given as, “to provide structural support”.

The bones and cartilage of many animals are composed of ECM. Skeleton provide the structural support as well as it facilitates movement. Moreover, it also provides strength and plays an important role in the proper arrangement of cells and cell signaling. Hence, option b. is incorrect.

Option c. is given as, “to organize cells and other body parts”.

ECM attached to the cells play an important role in the proper organization of cells. Moreover, it also provides strength and structural support, and plays an important role in cell signaling. Hence, option c. is incorrect.

Option d. is given as, “cell signaling”.

Cells in multicellular organisms sense their environment through ECM. Moreover, it also provides strength and structural support and plays an important role in the proper arrangement of cells. Hence, option d. is incorrect.

Hence, the options a., b., c., and d. are incorrect.

Conclusion

Thus, the function of the extracellular matrix in animals is to provide structural support and strength. It also plays an important role in proper arrangement of cells and in cell signaling.

Your goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants.   Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus. Observed Data: Total white seeds: 45 (resistant plants) + 6 (susceptible plants) = 51 Total black seeds: 7 (resistant…

Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses. Visual Reading Tool: Two-Factor Cross: F₂ The Punnett square shows the results of self-crossing the F, generation of a cross between round yellow peas and wrinkled green peas. 1. List the different genotypes in the F, generation. What is the…
