ipn [44]
A) Discuss the anatomical changes that occurred in the bipedal hominin
The changes that occurred are the loss of the capability in hands to grasp on branches. This is because of the presence of an opposable thumb. Another change is the loss of walking on 4 legs. The hominids started to have an upright posture, have long legs and walk on their two feet.

b) How they reflect habitat adaptation
The species lived in wooded areas like forests. This is why they required the grasping abilities on their feet and hands to be able to move in the trees while holding branches. Shifting to unwooded areas like the grasslands made them lose some of their abilities. This is because they were no longer needed.

c) Discuss the hypothesis that propose why the change occurred.I
It was necessary for change to occur due to the fact that forests were becoming fragmented and patchy. Food also became dispersed and scarce. This made the species use more energy to get food and also have free hands for them to be able to pick up food. They also gained an upright posture.

d) How can 3D scans and printing be applied to other areas of science.
3D scanning has been used to scan many objects from different museums. It has also been used to identify the age of fosils and artifacts. 3D printing can be used to create prototypes in scientific technology research. It is also used to analyse features of objects.

e) What applications can they have
3D scanning and printing has been applied in architectural surveys to provide accurate measurements increasing on productivity and saving on time. It has also been used in health to create a detailed study of body parts and produce comfortable prosthetic limb for patients.

Answer:

1.capsule

2.membrane composed mostly of lipopolysaccharide

3.membrane composed mostly of phospholipids

4.peptidoglycan

Explanation:

The cell wall of gram-negative bacteria is located outside the cell membrane and is composed of a single layer of peptidoglycan, followed by a second membrane composed of phospholipids (often called outer membrane) and finally a lipopolysaccharide layer, these three elements constitute the gram-negative envelope. Also, some bacteria produce a viscous secretion that spreads in the surrounding environment, forming a slime layer known as a capsule.

Positively charged DNA migrates more rapidly than negatively charged DNA b. Longer DNA fragments migrate farther on a gel than s
CaHeK987 [17]

Answer:

<h2>c. Migration distance on a gel is inversely proportional to DNA fragment size </h2>

Explanation:

  • Deoxyribonucleic acid is a genetic material that is a type of macromolecule.
  • It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group.
  • Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role.
  • Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size.
  • So the migration distance is inversely proportional to the DNA fragment size.
