Answer:
The parietal layer of the serous pericardium is also known as the epicardium of the heart wall.
Explanation:
The pericardium is a sac composed of two layers which surround the pericardial cavity. The two layers of the pericardium are the fibrous and serous pericardium and the serous pericardium is further divided into two layers: the visceral and the parietal layers.
The fibrous pericardium is composed of the thick connective tissue and thus prevents overfilling of the ventricles.
The parietal pericardium lines the internal surface whereas the "visceral pericardium layer" is the innermost layer and is known as the epicardium of the heart wall.
Thus, the selected option is correct.
The causes may include the species that are native to that place could suffer a lack of food the food chain can become imbalanced and the non-native species could kill of the native species or destroy the natural environment

Answer:
Protein combining
Explanation:
The strategy involving the combination of two plant proteins to get all the essential amino acids is referred to as protein combining.
<em>The practice of protein combining is common among vegans due to the general belief that a single plant-based protein does not contain all the necessary amino acids for the body. Thus, one would need to combine 2 plant-based proteins in order to get all the essential amino acids for adequate health. </em>
Answer:
b. Pleiotropy
Explanation:
The term “pleiotropy“ refers to a situation in which variants in a single given gene have a number of different, seemingly unrelated effects in the resulting phenotype.
For instance: patients with mutations in the COL1A1 gene (codifying for collagen alpha-1 chain) may present with a genetic disease called “osteogenesis imperfecta”, characterized by (among other findings) bluish sclera, brittle bones, and deafness. All those disparate clinical manifestations may be traced back to the inability of the body to produce normal type 1 collagen.
