Answer:
antigen-MHC protein complexes
Explanation:
Helper T-cells recognise antigens that are complexed with MHC proteins and interact with target cells. Antibodies can be produced against a single antigen in a variety of ways. Toxic shock syndrome is a relatively mild condition that resembles other minor allergy responses. Antigen-presenting cells break down superantigens.

<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>
Answer:
I think it's A: Sodium is needed to generate an action potential
It is not possible to determine this from this info. Thus, option "B" is correct.
<h3>What is standard error of mean?</h3>
The standard error of mean is computed by dividing the standard deviation to the square root of sample size. It can be represented as
The standard deviation of the sampling distribution is known as the standard error of mean because it measures the accuracy of sample mean as compared to population mean.
Thus, option "B" is correct.

According to an answer from another and a bit of my own research;
A decomposer is exactly what it sounds like, an organism that decomposes something and feeds off of it. You can eliminate the answers "Owl" and "Hawk" from a first glance as they are both consumers. Looking at it again, an "Ant" is <em>not </em>a decomposer, but rather, a consumer just like your other two options. This leaves "Fungus", something that decomposes it's food.
Please forgive me if I'm wrong. Feel free to ask for more information and I will scour the internet to see what I can find. <3
