Answer:
Phobia.
Explanation:
Phobia may be defined as a type of anxiety disorder that are marked by the excessive and persistent fear of the situation or any object. This phobia might result in the sudden fear.
Melissophobia si known as the phobia of the bees. The individual develop a persistent fever on seeing the bees. As billy was once stunged by the hive. She has develop the extensive fear against the bees.
Thus, the answer is phobia.
Answer: This moth has evolved
Explanation:
Evolutionary patterns show different patterns. One of the patterns is that: one species gradually transform into another species.
The above mentioned pattern is responsible for the moth's ability to lay more eggs and have more surviving offspring than other moths in the area. The moth is gradually transforming, so also its offspring will inherit these new traits, and it would further demonstrate evolution of one species.
Thus, it can be concluded that the unique ability of this moth over other moths is because the moth has evolved.
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.
Answer:
Macrophages are part of your innate immune system, which is antigen-independent and does not require activation.
Explanation:
Macrophages phagocytize (internalize) all non-self pathogens it encounters. These do their job without activation. Other cells in the innate immune system include basophils, neutrophils, eosinophils (these cells are polymorphonuclear leukocytes), mast cells, and dendritic cells, which act as the bridge between your innate and adaptive immune system.
All of the other entities listed above are part of your adaptive immune system. The adaptive immune system is antigen-dependent and requires activation. This section of your immune system responds differently to different pathogens, and has the bonus of having immunologic memory, the ability to remember pathogens after infection and respond much quicker upon secondary and tertiary encounters.
Note: All lymphocyte types begin as naïve cells, which then differentiate into their fully matured form upon activation.
Helper T cells are a type of CD4+ T cell that has the job of activating B and T lymphocytes. There are two different types of T helper cells: Th1 and Th2. Th1 cells secrete the cytokine interferon-gamma (IFNγ), and is primarily involved with the stimulation and activation of cytotoxic T cells, while Th2 cells secrete a variety of cytokines and are responsible for activating and assisting with B cells to make antibodies. To make a long story short, Th cells interact with APC (Antigen Presenting Cells), specifically their Class II MHC (a group of genes that present exogenous proteins). The Th cells then proliferate and gain the ability to activate these APC cells and provide the necessary signals to activate B and T cells and make them proliferate and do their specific function.
I'm not sure, but I think the answer might be false, because I'm pretty sure you can feel if someone or something is pressing down on your leg or arm.
