I think the answer is Endospore. I'm sorry if I'm wrong...
Explanation:
Whereas primary tissues allow for vertical growth, secondary tissues allow for lateral growth: they allow stems and roots to become wider. In roots, the formation of both secondary meristems involves the pericycle.

Answer:
(1) glycerophospholipids ⟶ (C) lipids with phosphate-containing head groups
(2) cerebrosides ⟶ (D) fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) gangliosides ⟶ (B) anionic sphingolipids containing one or more sialic acid residues
(4) sphingolipids ⟶ (A) built on sphingosine
Explanation:
1) Choline (Fig. 1) is a glycerophospholipid. It is a glycerol-based lipid with a phosphate-containing head group.
(2) Galactosylceramide (Fig. 2) is a cerebroside. It contains a fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) Gangliosides are glycosphingolipids that contain sialic acid. GQ1b (Fig. 3) is one of the most abundant gangliosides in the human brain. The carboxyl group of the sialic acid is in the ionic form.
(4) Sphingomyelin (Fig. 4) is a sphingolipid. It is based on sphingosine, with a phosphocholine head and a fatty acid chain.
Answer:
C. Meiosis produces new combinations of chromosomes.
Explanation:
Compared to mitosis, meiosis divides TWICE and has EIGHT stages of rather than mitosis with the regular four stages.
The end result in Meiosis produces haploid cells in which half of the amount of chromosomes are produced in each individual cell, therefore Meiosis produces new combinations of chromosomes.
A. is incorrect because Meiosis does NOT create genetically identical cells.
B. is incorrect because Meiosis creates a HALF set of chromosomes (or just half than the original amount).
D. is incorrect because DNA is not produced during meiosis.
