<em>"No man is an island.” This saying is also true for organisms in an ecosystem. No organism exists in isolation. Individual organisms live together in an ecosystem and depend on one another. In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival.
</em>
<em>So what do these interactions look like in an ecosystem? One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. While there are a lot of fancy words related to the sciences, one of the great things is that many of them are based on Latin or Greek roots. For example, heterotroph becomes easier to remember when you realize that in Greek, “hetero” means “other” and “troph” means food; in other words, heterotrophs eat other organisms to get their food. They then use the energy and materials in that food to grow, reproduce and carry out all of their life activities. All animals, all fungi, and some kinds of bacteria are heterotrophs and consumers. </em>

The advantage to a scientist is that it makes calculations easy using exponential functions. The disadvantage is that it may not capture some subtle complication that changes the answer at the fifth place after the decimal point.<span>

Hemoglobin is responsible for transporting OXYGEN within the blood.
Answer:
Question 1. The steps occur in the following order:
INTERPHASE
1. G1
2. S
3. G2
MEIOSIS I
4. Prophase 1
5. Metaphase 1
6. Anaphase 1
7. Telophase 1
8. First Cytokinesis
MEIOSIS II
9. Prophase 2
10. Metaphase 2
11. Anaphase 2
12. Telophase 2
13. Second cytokinesis
Question 2
Sister chromatids are created here (interphase)
The 2 X chromosomes pair (prophase 1)
A cell exists with one X chromosome that has 2 attached sisters (prophase 1)
An X chromosome appears in which the 2 sisters have different alleles (prophase 1)
2 X chromosome sisters move in opposite directions on the spindle (anaphase1)
Explanation:
During interphase the cell prepares to divide. During meiosis 1 Homologous chromosomes are segregated and the ploidia is reduced from diploid to haploid in a reductive division where the sister chromatids are held together. Unlike meiosis I, meiosis II is an "equational" division analogous to mitosis where sister chromatids are secreted creating four haploid cells.
Answer:
In an allergic response, which substance initiates inflammation?
Histamine initiates inflammation in an allergic response
Explanation:
Histamine is a chemical that is being released during allergic response which initiates inflammation
