Fruit flies are eukaryotic organisms. Describe how the genetic material of a fruit fly is stored in its cells.

Answers

Answer 1

Answer: The genetic material of a fruit fly, like all eukaryotic organisms, is stored in the cell nucleus. Here's how it is organized:

1. **Nucleus:** The nucleus is a membrane-bound organelle within the cell where the genetic material is located. It is surrounded by a nuclear envelope, which consists of two membranes, and has pores that control the passage of molecules in and out.

2. **Chromosomes:** Inside the nucleus, the genetic material is organized into structures called chromosomes. In fruit flies (Drosophila melanogaster), they typically have four pairs of chromosomes, totaling eight chromosomes. These chromosomes contain the DNA molecules that carry the genes.

3. **DNA:** DNA (deoxyribonucleic acid) is the molecule that makes up the genetic material. It has a double-helix structure and consists of nucleotide units. Genes, which are specific sequences of DNA, encode the instructions for building and maintaining the organism.

4. **Histones:** DNA in the nucleus is wrapped around proteins called histones. This complex of DNA and histones is called chromatin. Histones help in packaging and organizing the long DNA strands within the limited space of the nucleus.

5. **Nucleolus:** Within the nucleus, there is a region called the nucleolus where ribosomal RNA (rRNA) is synthesized and ribosome assembly begins. Ribosomes are essential for protein synthesis.

6. **Mitochondria and Chloroplasts:** While most of the genetic material is in the nucleus, eukaryotic cells also have DNA in other organelles. Mitochondria (in animal cells) and chloroplasts (in plant cells) have their own small genomes, a remnant from their evolutionary origins as independent organisms.

In summary, the genetic material of a fruit fly is stored in the form of DNA, organized into chromosomes within the nucleus of its eukaryotic cells. This DNA contains the instructions for the fly's development, growth, and functioning.

Which of these statements would be MOST important to include in an objective summary of this article? Plant and animals reproduction

Answers

Answer:

an objective summary of an article on plant and animal reproduction, it would be important to include key information such as:

1. Overview of plant and animal reproduction processes: Provide a general description of how plants and animals reproduce, including the different mechanisms and strategies involved.

2. Importance of reproduction for species survival: Highlight the significance of reproduction in ensuring the continuation and survival of plant and animal species.

3. Key factors influencing plant and animal reproduction: Discuss the various factors that can impact plant and animal reproduction, such as environmental conditions, mating behaviors, pollination, seed dispersal, and reproductive strategies.

4. Reproductive adaptations and diversity: Explore the diverse range of reproductive adaptations and strategies found in different plant and animal species, showcasing the remarkable variety of reproductive mechanisms in nature.

5. Implications for conservation and management: Address the relevance of understanding plant and animal reproduction for conservation efforts, ecosystem management, and addressing issues related to declining populations or endangered species.

Remember, the specific statements to include in an objective summary would depend on the content and focus of the article you are summarizing.

All of the following are important roles of the skeletal system exceptA. organ protection
B. movement
C. storing minerals
D. regulating body temperature

Answers

The answer is D. The ribs PROTECT the lungs and the heart. They allow you to move and they store minerals such as calcium. However it is the brain and the blood vessels that regulate the body temperature not the skeletal system.

On the pH scale what results means the water is acidic 9.2, 7.0, 3.2, 10.0?

Answers

A water that has a pH (potential hydrogen) of 3.2 would be the most acidic. That is because 7.0 is the neutral phase or measurement of a substance or a solution. Anything that is below 7.0 is acidic, the lower it is the more it becomes acidic. Anything that is higher than 7.0 is basic (alkaline) opposite with the acid, the higher it gets the more it is a basic.

HELPP MEE PLEASEE!!!!

Answers

Answer: there are six possible genotypes

Explanation:

With three alleles 1, 2, 3

genotypes: 11, 12, 13, 22, 23, 33. First we must appreciate that genes do not act in isolation. The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype.
