Image is not available in the question so, the correct image is attached below.
Answer:
D. codes for a specific trait
Explanation:
chromosome is defined as a DNA molecule found in the nucleus of most living cells which carry genes and transfer the genetic information.
The part labelled b in the image is gene. The function of gene is to code for a specific trait.
Genes are responsible for carrying traits that form the genotype and phenotype of an organism. where genotype shows the differences in genetic formation and phenotype shows observable characters in an individual such as color, height and features.
Hence, the correct option is D.
Answer: The option that contributes to the ease of transmission is 2 ( Low infectious dose).
Explanation:
Giardiasis is an infection that affects the intestine which is caused by a parasite known as giardia intestinalis. The giardiasis surveillance data recorded by the CDC, was done to educate public health practitioners and health-care providers about the scope and magnitude of giardiasis. It also provided different route through which the parasite can be transmitted to uninfected individual and these include:
--> Waterborne transmission: In this route of transmission, an individual becomes infected when they drink contaminated water from recreational water(pools) or streams.
--> Foodborne transmission: In this route of transmission, an individual becomes infected when they eat contaminated uncooked foods or foods that become contaminated after cooking.
--> Person to person: in this route of transmission, a healthy individual becomes infected through ianal sex practice.
The LOW INFECTIOUS DOSE of the parasite contributes to the ease at which transmission occurs through the above mentioned routes. The parasite has a two stage life cycle, the trophozoite and cyst. Ingestion of as few as 10 cysts can lead to giardiasis Infection.
Answer:
1.) spindle fibers and centrioles form
2.) chromosomes align on metaphase plate
3.) chromosomes move to opposite poles
4.) two identical nucleotides form
Mitosis is important because it is responsible for the growth of is responsible for human development.
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation:
Alright so three different alleles are A, B, and O.
A dominant to O
B is dominant to O as well
O is recessive to A and B
