  1. a. What is a larva?
  2. b. How does a larva differ from a juvenile form of an animal?
  3. c. By what process does a larva transform into a juvenile?

a.

Expert Solution
Check Mark
Summary Introduction

To describe: The larva.

Introduction: Some animals including humans develop directly into adults. The life cycle of most of the animals include at least one larval stage.

Explanation of Solution

Larvae are juvenile forms of many animals. It is a free-living and sexually immature form of an animal. Animals with indirect development undergo the larval phase before metamorphosis into adults. Different animals have different types of larval forms that are generally different from the adult form.

Summary Introduction

To determine: The way in which the larva differs from a juvenile of an animal.

Introduction: Metamorphosis is part of development. During metamorphosis, the structure and morphology of the animal are completely changed.

Explanation of Solution

The juvenile form of an animal resembles the adult physiologically. However, it is sexually immature. Therefore, the larva differs from the sexually mature adult.

c.

Summary Introduction

To determine: The process by which a larva transforms into a juvenile.

Introduction: Animals with indirect development undergo the larval phase before metamorphosis into adults. However, in most of the animals, the life cycle includes at least one larval stage.

Explanation of Solution

The larva transforms into a juvenile by metamorphosis. Metamorphosis is the developmental process, during which the complete change in the structure and morphology of the animal takes place.

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4 pts)? 12pt v R Paragraph V BIU A श्र > B
There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction. Tree SSR Type your answer here: Primers Nucleotides Polymerase Target sequence Number of copies
