The question is basically asking which of these can be known by just looking at the coin. It cant be the last one because we don't have time to research about the influence Indians had on us history. The first one is wrong because we are just looking at the coin, we don't know anything about it other than it's outside appearance. We are once again taking a look not studying the coin so we can eliminate the second one.
<span>There is a woman’s face on one side of the coin. That is an observation, be cause its obviously presented. Observations are a crucial element when performing lab's in biology. </span>
<span>Hope I helped. :) </span>
I think the answer would be C. If there is plenty of water, how would too much water be lost? Hope this helps!
Answer:
Physical exercise and nutrition are two important components in how you respond to stress. When your body is healthy, your mind can be healthy and vice versa. Physical exercise is proven to be a great stress reliever and also helps to improve your overall quality of life.
Explanation:
Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.
Explanation:
Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene.
</u>
<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype. During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.
By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)
In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.
