Aids is one of the disease that damage little by little the immune system until the human body die.
I found the exercise on the internet. Attached is the chart and the rows. On the left we have "plant tissue", then on the middle top - "dermal" - and just below - "ground". Straight in front of "ground", the term is "c<span>ollenchyma".
The correct row would be D.
1. is vascular because that's the other type of plant tissue besides the ones that are already present in the chart.
2. and 3. - s</span>clerenchyma and parenchyma - are indeed types of ground tissues next to collenchyma.
4. and 5. - x<span>ylem and phloem - are the types of tissues present in vascular plants, they work as vessels where water and nutrients are conducted.</span>
<span>Three months after fertilization and development of a placenta around the developing fetus, the corpus luteum regresses and forms the corpus albicans.</span> Formed placenta takes over progesterone production (which was the role of corpus luteum) and the corpus luteum degrades into a corpus albicans. The corpus luteum is being broken down by macrophages, in a process called luteolysis. The remains of the corpus albicans may persist as a scar on the ovary.
Phosphorus is an important element for all forms of life. The phosphorus cycle differs from the other major biogeochemical cycles in that it does not include a gas phase; although small amounts of phosphoric acid (H3PO4) may make their way into the atmosphere, contributing—in some cases—to acid rain. The water, carbon, nitrogen and sulfur cycles all include at least one phase in which the element is in its gaseous state. Very little phosphorus circulates in the atmosphere because at Earth’s normal temperatures and pressures, phosphorus and its various compounds are not gases. The largest reservoir of phosphorus is in sedimentary rock.
There’s an explanation. I hope this helps!
