Answer:
1. Map-based genome sequencing: a; c; f; g
2. Whole-genome shotgun sequencing: b
3. Both sequencing methods: d; e
Explanation:
Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.
In moving from the outside environment to the inside of a bacterium, the first layer encountered would be Glycocalyx.
The cell coat or outermost layer of bacterial cells is called the glycocalyx. Glycoproteins, glycolipids, and proteoglycans make up its composition.
It is a network of lipids and membrane proteins connected by polysaccharide chains. On the lumen side, it encircles the vascular endothelial cells.
Various bacteria have varied glycocalyx layers with different compositions and densities. It serves as a protective layer and participates in cell interaction, signalling, and identification.

They are a type of photoreceptor in the retina responsible for color vision. There are three types of cones; blue, green and red mainly packed in the fovea. The other type of photoreceptor is the rods responsible for black and white vision and are mainly located in the peripherals of the retina. Rods can perceive dim light, unlike cones.
Answer: B- the thickness and shape of a bone being dependent on stresses placed upon it
Explanation:
Tendons hold together bones and muscles, they make possible the movement and rotation of joints, and they assist in skeletal muscle coordination
