There are 5 main types of pathogens that can harm other organisms and cause diseases. They are viruses, bacteria, fungi, Protozoa, and worms.
Explanation:
Recessive alleles lack the power to express the phenotypic traits of an organism. In order for the specific trait to be expressed, 2 copies of the recessive allele or homogenous recessive genotype is needed in the organism.
Answer:
The main function of the circulatory system is a To transport material throughout the body.
Explanation:
Blood in an important component of circulatory system.Blood contain Red blood cell that in turn contain hemoglobin which helps in the transport of oxygen and carbon dioxide to and from various body tissue.
The circulatory system also helps in the transport of nutrients such as glucose to various parts of our body such as heart,muscle,brain etc.The glucose molecules are utilized by those organs to perform their physiological functions.
The circulatory system also transport various hormone from the region of secretion to the target cell .
The right answer is Scientists should conduct long-term studies of DNA technology to determine the consequences.
DDT is a potent insecticide: it kills by opening the sodium channels of insect neurons, destroying them instantly, leading to spasms and then death. Some genetic mutations acting on the sodium channels can make some insects resistant to DDT and other insecticides working on the same principle.
The US Environmental Protection Agency has categorized DDT into the B2 class, that is, potential carcinogen for humans. This supports the fact that the insecticide acts on human DNA.
The expression or appearance of a particular trait is known as an organism's phenotype
The term "phenotype" describes an organism's observable physical characteristics, such as its appearance, growth, and behavior. The genotype, or collection of genes that an organism possesses, as well as environmental impacts on these genes, together determine its phenotype.
Earwax type, height, blood type, eye color, freckles, and hair color are phenotypic examples in humans. A phenotype is more than just a physical characteristic. A phenotype may also include a person's behavior. The dog breed known as the Border Collie, which was developed to herd sheep, serves as an illustration of inherited behavior.
