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.
Cells of the skin and digestive tract are continuously sloughed off and replaced by new ones due to mitotic division.
Some body parts of animals and plants can be regenerated by mitotic cell division.
Vegetative propagation in plants and budding in some animals also occurs due to mitosis.
Answer:
B. The volume of the liquid should be measured before it is heated.
Explanation:
A student made serious mistake that he did not measure the volume of the liquid before heating.
The scientific experimentation along with care and attention need a proper protocol which a scientist needs to follow to get the results.
The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.
<em>All other options seem less appropriate than Option B, therefore B is the right answer.</em>
I hope it help!
Answer:
The allele frequencies of both populations are likely to be similar.
Explanation:
An allele is a variant form of a given gene. Sometimes different alleles can cause variations in the observable characteristics of the species examined.
In the option given the chance that alleles are similar is very high because both populations exchange migrants very frequently and at a high rate so the genes of both populations are mixed very often.
I hope this answer helps you.
<span>The building from the list provided with the highest likelihood of air pollution is a tightly sealed house with an unvented water heater. The school with leaks will let air exchange happen so that isn't it, and having a carbon monoxide detector only reports existing air pollution it doesn't prevent air pollution, it could have issues but we don't know. The tightly sealed house with the unvented water heater is a near sure thing.</span>
