qué ventajas le trajo al ser humano el poder andar en 2 patas.

Answer:
The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".

Experimental Scenario
Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster
when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the
time it takes for the pendulum to swing twenty times when the weight is moved to its lowest position.
Donna begins to move the pendulum up by 1 cm and continues to measure the time for twenty swings
of the pendulum. Donna records her data
SCI 1.4 Investigation Plan
1) Provide a brief description of the methods that are being used to run the experiment
Answers
Answer:
Reduce the mass and measure the speed of pendulum.
Explanation:
First measure the swings of the pendulum at its original weight. After that some weight is removed from the pendulum and again measure the number of swing of pendulum at specific time period. We have to reduce mass of pendulum and then measure the number of swings. In this way, this experiment moves forward and we can find out the impact of mass on the speed of pendulum.

extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.

D Light reactions
Answers
It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.
What is photosynthesis ?
Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.
Hence, the picture depicts the process of gylcolysis , stage of photosynthesis i.e option (c)
