Answer/Explanation:
Only the soft tissue is preserved. Normally the hard tissues are preserved(bones). But since the bones decomposed and was later filled with sediment, only the soft tissue was actually left by the animal.
The correct answers is : <span>They allow the exchange of gases between cells in the leaf and the external environment
The stomata are small openings that can be found on both the upper and the down part of the leaf and they are connected to the plant's vascular system.
These openings enable the plant to get rid of excess water in the form of vapor and to take CO2 from the atmosphere that is essential for the process of photosynthesis. </span>
<span>The correct answer for the question is Non-disjunction. Non-disjunction occurs in cell division when chromosomes do not divide properly. It can occur during mitosis, meiosis I and meiosis II. In mitosis it occurs when sister chromatids fails to separate in Anaphase. The result is that one cell receives both chromatids, while the other receives neither. Each daughter cell then has an abnormal number of chromosomes when mitosis is complete; one cell has an extra chromosome, while the other is missing one. In anaphase of meiosis I, it happens when a pair of homologous chromosomes does not separate. In meiosis II, it happens when a pair of sister chromatids fails to separate properly during anaphase of meiosis II, one daughter cell will have an extra chromosome and one daughter cell will be missing a chromosome.</span>
Answer:
Glucocortocoid hormones performed above roles.
Explanation:
Genreally they are any steroid hormones produce by the Cortex of adrenal glands with anti-inflammatory and immunosuppressive activities..
They coordinate the withdrawal of immune cells from the blood and storage sites to tagger ares for immune reactions
