Why did scientist reject Lamarck's idea of evolution?

Physics
1 answer:
laila [671]3 years ago
3 0

Explanation:

Lamarck's theory of evolution, also called as theory of inheritance of acquired traits was rejected because he suggested that the acquired characteristics which an organisms acquires through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individuals set of genes.

Answer: Traits acquired during a lifetime are not passed through offspring. (C.)

98 Points and brainlyest for 5 Science questions please I need it doe before 2:30 ET!!!

Picture #1:
GPE = (mass) x (gravity) x (height)
GPE = (2 kg) x (9.8 m/s²) x (40 m) = 784 joules

KE = (1/2) (mass) (speed²)
KE = (1/2) (2 kg) (5 m/s)²
KE = (1 kg) (25 m²/s²)  =  25 joules

Picture #2:
KE = (1/2) (mass) (speed²)
KE = (1/2) (2 kg) (10 m/s)²
KE = (1 kg) (100 m²/s²)  =  100 joules

Picture #3:
GPE = (mass) x (gravity) x (height)
GPE = (20 kg) x (9.8 m/s²) x (2 m) = 392 joules

KE = (1/2) (mass) (speed²)
KE = (1/2) (20 kg) (5 m/s)²
KE = (10 kg) (25 m²/s²)  =  250 joules

Picture #4:
GPE = (mass) x (gravity) x (height)
98 joules = (1 kg) x (9.8 m/s²) x (height)
Height = (98 joules) / (1 kg x 9.8 m/s²)
Height = 10 meters

Picture #5:
GPE = (mass) x (gravity) x (height)
39,200 Joules = (mass) x (9.8 m/s²) x (20 m)
Mass = (39,200 joules) / (9.8 m/s² x 20 m)
Mass = 200 kg

Why might a wine glass survive a fall onto a carpeted floor but not onto a concrete floor? 1. since the carpet is softer than th
user100 [1]
Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.

Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.

The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.
