Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
They would have serious, perhaps fatal effects because the red blood cells would tend to burst
Answer:
B. The amount of lee that melted.
Explanation:
The dependent variable is more of what results from an action during an experiment. It is actually what is being tested for. In the experiment, the scientist seeks to understand the effect of salts on melting point of ice. He selects the different salts which can cause a ice to melt (independent variables) then he sets up to find out the effect of the salt on the ice.
He cannot control how much ice will melt. The properties of the salts would determine the extent and rate of the dissolution of the ice pack. This is the dependent variable which relies on the nature of the salt.
Answer:
inhibits translation
Explanation:
Bacteriostatic macrolide antibiotic produced by Streptomyces erythreus. Erythromycin A is considered its main active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process that inhibits peptidyl transferase activity and interferes with the translocation of amino acids during translation and protein assembly.
The bacteriostatic effect consists in producing the inhibition of bacterial growth; Meanwhile, immunogenesis is expected to provide the necessary defensive elements for disease control. Therefore, these antimicrobials should not be indicated to the immunocompromised patient. They act in the stationary phase of bacterial growth.
Some antibiotics have a bactericidal or bacteriostatic effect depending on whether the drug acts in vivo or in vitro, and depending on the dose administered. For example, Amphotericin B, has fungistatic effect in vivo and fungicide in vitro; Streptomycin and erythromycin have bactericidal effect when administered at high doses and bacteriostatic effect if administered at low doses.
Answer:
False
Explanation:
Stem cells are different type of cells in human body that can develop into different other body cells like muscles cells or brain cells and they gave the capability to renew themselves through mitotic cell division.
Stem cells are not lost in childhood but can be use to treat diseases or infection, it can be use to grow new cells and replace damaged body cells.
