I think it would be cold front ^^, I hope it helps!
Answer:
Option-B
Explanation:
Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.
1. Total color blindness is not a rare disease in animals.
2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.
3. The red-green color blindness is more common than the blue-yellow color blindness.
4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.
Since all options except Option-2 are incorrect therefore option-2 is the correct answer.
50% because both are the same Genotyle dominant wise and recessive wise so it will have a fifty fifty chance of having wrinkled seeds
Answer:
We have just seen that pathogens constitute a diverse set of agents. There are correspondingly diverse ranges of mechanisms by which pathogens cause disease. But the survival and success of all pathogens require that they colonize the host, reach an appropriate niche, avoid host defenses, replicate, and exit the infected host to spread to an uninfected one. In this section, we examine the common strategies that are used by many pathogens to accomplish these tasks.
Explanation:
The first step in infection is for the pathogen to colonize the host. Most parts of the human body are well-protected from the environment by a thick and fairly tough covering of skin. The protective boundaries in some other human tissues (eyes, nasal passages and respiratory tract, mouth and digestive tract, urinary tract, and female genital tract) are less robust. For example, in the lungs and small intestine where oxygen and nutrients, respectively, are absorbed from the environment, the barrier is just a single monolayer of epithelial cells.
Skin and many other barrier epithelial surfaces are usually densely populated by normal flora. Some bacterial and fungal pathogens also colonize these surfaces and attempt to outcompete the normal flora, but most of them (as well as all viruses) avoid such competition by crossing these barriers to gain access to unoccupied niches within the host.
