These variations are most likely the result of polygenic effects. Polygenic traits are controlled by many genes.

<h3>Polygenes and inheritance</h3>

The phenotype is any observable feature of an organism, which depends on genotype and environment.

The inherited genes largely determine different phenotypic features (e.g., eye color, weight, etc).

Traits controlled by a single gene are called monogenic, whereas traits controlled by two or more genes are known as polygenic.

A tree grows in an environment where there are generally four or five years of severe drought followed by a rainy year. How will
Thepotemich [5.8K]

Answer:

Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes.

Explanation:

The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age. In dry environments, such as the Middle East or U.S. Southwest, tree rings typically record wet or dry years, and in cooler areas (high latitudes or high elevation), the ring widths are often a proxy for temperature.

How are epimysium, perimysium, and endomysium interrelated? group of answer choices'
My name is Ann [436]

Entire muscles are encased in the epimysium. The perimysium, which is connected to the epimysium, separates groups of muscle fibres into fasciculi. Individual muscle fibres are encircled by a delicate network of connective tissue fibres, blood arteries, lymphatic vessels, and nerves called the endomysium.

The collagen fibres of tendons are made of endomysium, perimysium, and epimysium, and they serve as the tissue link between muscles and bones by indirect attachment. Intermittent perimysial junction plates serve as its connection to the perimysium.

The perimysium, which surrounds bundles of muscle fibres, the endomysium, which surrounds individual muscle fibres, and the epimysium, which surrounds the muscle, are the three scale levels at which connective tissue of the muscle may be identified.
