Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
Answer:
C
Explanation:
recessive traits can only be seen when there is no dominant trait present.
Answer:
Protein is the important biomolecule that acts as building block of the protein. Proteins are inserted into the biological membrane and consists of transmembrane and integral membrane proteins.
The alpha helices and beta sheets are present in the bio membrane. The organism living at low temperature has high alpha helices and low beta sheets because alpha helices has high mobility, less rigidity and makes enzyme active at low temperature.
Answer:
phenotypes
a. genotypes
A person's genotype refers to their genetic blueprint and it is fixed at conception. While A person's phenotype refers to the physical expression of their genetic code which can be altered by biological and environmental factors
Answer:
Option A
Explanation:
In this case, there are two varieties of horses: Domestic horses that are raised and bred by humans and Wild horses that lives in the wild. The issue of varieties in coat colour of domestic horses can be explained as what occured by selective breeding, also known as artificial selection which is a technique by which humans develop new offsprings with desirable and suitable characteristics. These breeders select two parents that possess beneficial phenotypic traits to mate, producing offsprings with those desired traits such as strength and also for coat colour as stated.
