Answer:

we often yhink of mutations as a negative thing, but that isn't always the case. these errors, or changes in DNA, are essential to evolution. usually they're neither good or bad, just different. alleles are what make us unique such as our hair color, skin color, height, etc

Lizard is a poikilothermic animal why

jeka57 [31]

Answer:

Lizard is a poikilothermic animal because lizards are those animals that do not require a fixed body temperature, their temperatures can fluctuate with little to no adverse effects to their overall health. 

Explanation:

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. By moving in and out of sunlight, reptiles can keep their body temperature at a steady level throughout the day.

The brain is a part of the central nervous system together with the spinal chord.
The other part of the nervous system is the peripheral nervous system which is consisted of nerves and ganglions.
Humans own their ability of speech to the three areas in the brain.
Broca's area is essential for forming words, Wernicke's area helps us understand the meaning of words and the arcuate fasciculus connects these two areas and gives speech coherence.

If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), subsequent analysis will show that 18O fir

Luda [366]

Explanation:

O2- this is produced by oxidizing water in the light reaction.

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). An increase in temperature will increase the rate of photosynthesis.

It happens in several complicated stages, photosynthesis is a rate-limited process, based on several conditions including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reducing agent.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen
