Answer:
A. The <u>d. extensor retinacula</u><u> </u>are the broad ligamentous sheets that contain the tendons of the anterior compartment muscles.
B. Inversion and dorsiflexion of the foot is achieved by contracting the <u>a. tibialis anterior</u> muscle.
C. The <u>b. extensor hallucis longus</u> muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The<u> </u><u>c. lateral condyle</u> of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Explanation:
The two extra options are the f. extensor digitorum longus and the e. medial epicondyle. The first one is a muscle in the anterior part of the legs that originates in the anterior lateral condyle of the tibia and the anterior part of the fibula. Its insertion is in the four phalanges of the 2, 3, 4, and 5 digits. The first digit has the insertion of the extensor hallucis longus. The extensor digitorum longus and the b. extensor hallucis longus has the same function, the extension of the toes, the extensor hallucis longus only extends the first digit, and the extensor digitorum longus extends the other four digits simultaneously.
The second extra option, the medial epicondyle, is in the femur. It is a prominence in the distal part of this bone. The tibial collateral ligament and the Magnus muscle insert in this part of the femur.

10% of the energy in a trophic level is passed to the next.
Amount to mouse = 10% x 4000 = 400 units
Amount to owl = 10% x 400 = 40 units
Amount available to bobcat = 10% x 40 = 4 units
4 units of energy will be available to the bobcat that eats the owl.
- The environment needs to change in order to natural selection to occur.
Reason:
Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2. Population has some genetic variations.
Reason:
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:
mutation and random mating between organisms
3. Nature select organism with specific traits to survive and reproduce.
Reason:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
The Venus flytrap is a species of plant. It naturally occurs in areas such as bogs and marshes with very little nutrients such as nitrogen. As such, it has evolved to capture prey such as insects, spiders, and other invertebrate and small vertebrates to digest, allowing it to gain nutrients from its food. Hope this helped!
