These changes can be natural, such as through variations in the solar cycle.
<h3>Climate history</h3>
Clam shells

Ice cores
1. 150 million years ago
Oldest rocks in the world
5. 3.8 billion years ago
Tree cores
3. 10,000 years ago
Ocean sediments
4. 200 million years ago
With this information we can conclude that these changes may be natural, such as through variations in the solar cycle. But since 1800, human activities have been the main driver of climate change, mainly due to the burning of fossil fuels like coal, oil and gas.

Answer:
diploid
Explanation:
A diploid cell is a cell that contains two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be a homologous chromosome set.
1. Contraction of the iliacus and psoas major produces flexion of the hip joint
2. quadriceps femoris muscle group
3. A combination of gluteal and thigh muscles also adduct, abduct, and rotate the thigh and lower leg. The tensor fascia latae is a thick, squarish muscle in the superior aspect of the lateral thigh. It acts as a synergist of the gluteus medius and iliopsoas in flexing and abducting the thigh.
4. triceps brachii
5. The major muscle that laterally flexes and rotates the head is the sternocleidomastoid
6. Rectus abdominis
7. The external obliques are the outermost abdominal muscles. They are also key participants in spinal flexion and the compression of the viscera. Individually, they act alongside the internal obliques in lateral flexion and spinal rotation.
8. abdominal external oblique muscle
9. external intercostal muscles
