identify the types of questions that interest behavior geneticists, and describe the elements of heredity: chromosome, dna, gene
baherus [9]

The interaction between genetics and environment and how this affects behavior, resulting in individual variances, is of particular interest to behavior geneticists.

The environment in this context refers to every external, nongenetic component of our life, including prenatal nutrition and the people and objects in our immediate surroundings.

Chromosomes:

Each of our cells contains 46 chromosomes, 23 from our mother and 23 from our father. Chromosomes are complicated, spiraling molecules formed of DNA that resemble threads and contain genes.

DNA:

We have over 30,000 genes, which are DNA segments that, when activated (expressed), serve as templates for the synthesis of different protein molecules, which serve as the foundation for our physical and behavioral growth.

Genome:

The entire collection of instructions for creating an organism, included in all of its chromosomal genetic material, is called an organism's genome.

Gene:

Combinations of mutations at certain gene locations serve to distinguish us from one another. The majority of human features are not controlled by a single gene acting alone, but rather by a number of genes working together.

Calories from saturated fats and/or added sugars in foods that have little or no nutritional value, such as sausages and ice cre
Viktor [21]

Calories from saturated fats and/or added sugars in foods that have little or no nutritional value, such as sausages and ice cream, are called Empty Calories.

Calories can be defined as the amount of energy extracted from the food which an individual eats throughout the day. According to dietary guidelines, a young person [20-25 years old] must intake between 1,600 and 3,000 calories per day.

Foods such as sausages, ice cream, pizza, and soft drinks have a high amount of empty calories because solid fats and added sugars are used in their manufacturing to add flavors and make the food more appealing but they have no nutritional value.

The amount of empty calories a person intakes should be decreased by avoiding such food items and drinks.

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
g100num [7]

Answer:

Explanation:

the purple allele (C) is dominant to the pink allele (c).

The frequency of C represents p while that of c represent q. Using the formula p+q= 1

The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).

Thud to find q which is the frequency of the c allele,

q = √0.153

q = 0.3912

From the formula p +q = 1 we can find p p = 1 - 0.3912

p which is the frequency of the C allele

p = 0.6088.

B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?
Degger [83]

Answer:

An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?

Acceleration= velocity/time

velocity=5mm= 0.005m

time= 1 hour= 60 seconds

A= 0.005/60

Acceleration= 0.000083m/s square
