Answer:
A : accessory obturator nerve
Explanation:
The accessory obturator nerve -found in about ten per cent of the population- is placed medial to the psoas major and anterior to the obturator nerve. It has a small size and emerges from the ventral divisions of the third and fourth lumbar nerves.
The obturator nerve is located on the ventral divisions of the second, third and fourth lumbar nerves in the lumbar plexus; the genitofemoral nerve is placed in the abdomen; the iliohypogastric nerve arises in the lumbar plexus and involves the lateral gluteal area and transverse abdominal muscles; while the ilioinguinal nerve operates from the first lumbar nerve to the iliohypogastric nerve.
Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
Answer:
abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organismsBiotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem
