Answer:
carbon dioxide is the product of photosynthesis
Answer: crossing over allows for genetic variation
Explanation:
crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).
Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.
Answer/Explanation:
<h3>Incomplete dominance</h3>
In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.
For example, consider flower colour.
- If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
- However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>
In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.
For example, consider flower patterns.
- If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
- However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))
1. Radiation - energy transmits through particles that ionize. Conduction - heat is transferred through a substance without moving the material. Convection - transfer of heat through movement.
2. Earth receives energy from the sun, which is transferred between Earth and its atmosphere.
3.<span>Wildland fires, dust storms, and volcanic activity. They release CO2, CH4, N20, and sulfur dioxide.</span>
4. Burning coal, releases carbon dioxide and other pollutants. Gasoline, releases air pollution. Factories, releases carbon dioxide, methane, and nitrous oxide.
It is true that the potential must be strong enough to send
a potential to the CNS. The stronger the potential, the more it will excite the
transmitter in relaying the message to another neuron, therefore, if this
happens, the more will it be easier to pass the message.
