5. Imagine that you encounter two color morphs of S. marcescens in natural environment. If you do not have any prior knowledge on the prodigiosin synthesis pathway of these Serratia species, will you consider the red and white Serratia colonies as one species or two species? Do you think we should designate species based on morphological traits or genetic differentiation? Without limiting to the S. marcescens experiment, provide evidence and example to support your claim.

Answers

Answer 1

Answer:

According to the given question that without prior knowledge on the prodigiosin synthesis pathway of these Serratia species, and we experience two different color morphs of the species. So, there is given or known preliminary morphological basis we will consider them different two different colonies. These can be identify only after genetically identify or study.

The morphological characterstics of the organism and the genetic identification both are equally important. So Giving any one more importance over other is not logical.

Morphologically we can differentiate the color of the colonies of mutants. The mutant serratia sp. are  known for eficient biosynthesis of prodigiosin, Thus on the basis of color characteristics of their colonies when grown on peptone glycerol medium we can identify.

To grow, plants require water. They cannot get this water unless it is available in the soil. Plants
obtain water from the soil through their roots. It then passes up the stem and to the leaves and
flowers. The plant does not take all the water available in the soil. Much of the remaining water
evaporates into the surrounding air.

What is the importance of the plasma membrane in cells?

The plasma membrane acts as a barrier in the cell, controlling the movement of molecules as well as some gases such as oxygen, carbon dioxide, and water that pass through it but not larger and more polar molecules. The importance of this is that it regulates and controls the inflow and outflow of substances such as hormones, etc.

All of the following are true of spermatogenesis EXCEPT: Question 18 options: DNA replicates once, but cells divide twice. The products are spermatozoa that each have a head, midpiece and tail. Spermatids containing 23 chromosomes (1n) are produced. One spermatogonium produces 4 spermatids Genetically diverse spermatids are created.

Answers

Answer:

One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.

Explanation:

Germ cells are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through mitosis, they originate more sexual cells, but through meiosis, they produce gametes -sperm and egg cells-. This process is known as gametogenesis.

Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.

Spermatogenesis is the process of production and maturation of sperm cells. Spermatogonia are the masculine diploid germ cells, carrying 46 chromosomes. These germ cells suffer mitosis to reproduce. Some of them stay as spermatogonia, and some others become primary spermatocytes, which are in charge of gamete production. Primary spermatocytes are also diploid cells, meaning that they still carry 46 chromosomes.

Each primary spermatocyte replicates its genetic material and then goes through meiosis I to produce two daughter haploid cells called secondary spermatocytes, each of them carrying 23 chromosomes. Each secondary spermatocyte will produce two other haploid daughter cells by meiosis II.

The total result from the two cellular divisions of each primary spermatocyte is four haploid daughter cells called spermatids.

During spermiogenesis, spermatids mature into spermatozoa or sperm cells. Each sperm cell characterizes by being composed of a head, midpiece, and tail.

DNA replicates once, but cells divide twice TRUE The products are spermatozoa that each have a head, midpiece, and tail TRUE  Spermatids containing 23 chromosomes (1n) are produced TRUE One spermatogonium produces 4 spermatids FALSE. One primary spermatocyte produces 4 spermatids.Genetically diverse spermatids are created TRUE

What are the functions of behavior?

Behavior is the range of actions and manners which are made by individuals, systems or artificial entities in a given environment. This can include other systems or organisms as well as inanimate physical environment.

The four main functions of behavior of an organism are attention, escape, access, and sensory needs. These four functions allow us to understand and categorize someone's actions, as well as determine the behavior of organisms such as finding food, reproduction, and avoiding the predators.

The meal Valerie is planning to eat at dinner has total 800 Calories. If 55% calories come from carbohydrate, 20% from fat and 25% from proteins, calculate the amount of carbohydrates, fats, and proteins (in grams) in the meal.

Answers

Answer:

Carbohydrate = 57.023g

Fats = 20.736g

Proteins = 25.919g

Explanation:

According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.

- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories

- 20% calories come from fat i.e. 20/100 × 800 = 160 calories

- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories

Since 7.716 calories = 1g

1. Amount of carbohydrates in gram = 440/7.716 = 57.023g

2. Amount of fats in gram = 160/7.716 = 20.736g

3. Amount of proteins in gram = 200/7.716 = 25.919g
