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.
Auxin, which is produced by the apical bud, encourages the growth of apical buds while inhibiting the growth of lateral buds that are located lower on the stem, toward the axillary bud.
<h3>
What does a shoot's apical bud produce?</h3>
Auxin, a hormone produced by the apical bud, travels via the plant's circulatory system (phloem) down the stem and prevents axillary buds from expanding, which would otherwise result in the production of additional side shoots from the plant cells.
<h3>What function does auxin serve?</h3>
Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance,and the transition to blooming..
<h3>What are the four roles that auxins play?</h3>
- Its primary uses are to stimulate shoot growth in culture and to enhance lateral and accidental shoot growth.
- aids in overcoming auxin-induced apical dominance.
- encourage the development of leaves' chloroplasts.
- encourages the mobilization of nutrients and delays leaf senescence.

Its because a long spine cacti can reproduce more because it has more survival capacity than the short spine cacti and because of this reason the short spine cacti cannot protect it self because it has a shorter spine that could protect itself from danger.
Answer:
In order to clone the sequence of the gene for one of the human crystallins found in the eye, there is a need for the application of polymerase chain reaction. In the process, the particular sequence of gene is denatured and then replicated various times to generate various clones of the gene sequence.
By producing various copies of the gene sequence for the human crystallin, that is, desirable, a scientist can examine various distinct characteristics of the protein as there is always more to examine with.
