Answer:
The correct answer is option D) "response to external stimuli".
Explanation:
The phenomenon of tree shedding their leaves during the autumn months is an example of plants response to external stimuli. The deciduous trees start shedding their leaves when light levels and temperatures drop, as a result of the flow of auxin being reduced and the levels of the hormone ethylene rise in the leaves. This process allows the trees to survive winter by conserving resources and protecting from being blown by the winds.
Answer:
In a dichotomous key you named then by their traits while in a branching diagram it already has the name and it's traits.
Explanation:
In dichotomous keys (also called single-entry or single-entry keys), a fixed sequence of alternatives must be followed, where multiple steps (including one or more characters) present two contrasting options (character states). As a result, only a single series of choices results in correct identification. Thus for each taxon there is a specific sequence of steps. An important factor of the dichotomous keys is that through them it is possible to name living beings through their characteristics.
A branch diagram can be used to represent a probability space. It can also be used to represent the various possibilities of a permutation or combination. This type of diagram provides a convenient way to organize information from a set of conditional events. In biology, the branch diagram shows the name and characteristics of a being and its relationship to different beings and characteristics.

A probe uniquely hybridizes to a specific target gene due to the principle of complementary base pairing, meaning it only binds to the gene with the exact complementary sequence.
A DNA probe will hybridize to a target gene but not to any unrelated genes because each probe is uniquely matched to a specific target gene sequence. This process takes advantage of the principle of complementary base pairing, where adenine pairs with thymine and cytosine pairs with guanine in DNA sequences. Hence, the probe, which is a short synthetic DNA sequence, will only bind with, or 'hybridize' to, the target gene that has the complementary sequence. For instance, if the probe sequence is AATGC, it will bind to the gene sequence TTACG but not to any unrelated genes with different sequences.

The backbone vertebrae, skull, and rib cage make up the axial skeleton. Among other types of cells, bone marrow produces red blood cells, which carry oxygen in the blood. Osteoblasts can eventually become osteocytes. If bones rapidly deconstruct faster than new bone tissue grows, this can lead to less dense and more fragile bones, a condition called osteoporosis. Ligaments such as the MCL and ACL connect bone to other bone at joints.
The backbone vertebrae, skull, and rib cage collectively constitute the axial skeleton, forming the central axis of the human body.
This vital skeletal component provides support and protection for the brain, spinal cord, and vital organs within the thoracic cavity.
Within bone marrow, various types of cells are produced, including red blood cells. Red blood cells are crucial for carrying oxygen from the lungs to tissues and organs throughout the body.
This oxygen transport is fundamental for cellular respiration and overall metabolic function.
This imbalance results in less dense and more fragile bones, a condition medically termed osteoporosis.
It increases the risk of fractures and bone fragility, particularly in older individuals or those with certain risk factors.
In addition to bones, ligaments are crucial connective tissues that play a significant role in the musculoskeletal system.
Ligaments, such as the MCL (Medial Collateral Ligament) and ACL (Anterior Cruciate Ligament), connect bone to bone at joints, providing stability and facilitating smooth movement.
They are essential for maintaining the integrity and functionality of the skeletal structure, ensuring proper joint function and preventing excessive movement or dislocation.
