Our star—the Sun—is a bubbling, boiling ball of fire. See Picture 1 to the right. It constantly belches out great clouds of hot gas. This gas is all charged up with electricity, too. This stuff travels at astounding speeds, some of it right toward Earth! This means that Earth’s weather happens inside the Sun’s weather!
Thank goodness Earth’s magnetic field (see Picture 2) and atmosphere protect us from most of this blast. Otherwise, the Sun’s weather would be OUR weather. Yikes!
However, we are still affected by the Sun’s atmosphere and its violent activities. We call this part of our weather “space weather,” because it comes to us through space from the Sun.
Answer:
Mrs. Ritter, whose blood type is B (Bi) is right in claiming that Ian - blood type A (Ai)- is the father of her baby, with blood type O (ii). Ex-boyfriend AB (AB) cannot be the father.
Explanation:
The blood type, according to the ABO system, is determined by the presence or absence of surface antigens A and B. In addition, genotypes can be co-dominant, in the case of A, B and AB, heterozygous (Ai or Bi) and recessive, in the case of group O (ii)
- <em>
</em><u><em>Type A</em></u><em> contains the antigen A and its genotype can be AA or Ai.
</em>
- <u><em>Type B</em></u><em> contains the antigen B, whose genotype can be BB or Bi.
</em>
- <u><em>Type AB</em></u><em> contains both antigens and a single genotype expression AB.
</em>
- <u><em>Type O</em></u><em> blood lacks surface antigens, its genotypic expression being ii.</em>
According to this, to check if Mrs Ritter's baby is Ian's child, a crossing can be done:
♂ Ai
♀ Bi
Alleles A i
B AB Bi
i Ai ii
<u>Ian and Mrs Ritter have a 25% chance of having a child with blood type O (ii), so the baby may be Ian's child</u>.
To find out why the ex-boyfriend can't be the father
♂ AB
♀ Bi
Alleles A B
B AB BB
i Ai Bi
It is not possible that Mrs. Ritter's ex-boyfriend is the father of the baby, as the possible offspring in the crossover are A, B or AB.
Answer:
The answer is given below.
Explanation:
Rescorla explain this finding by stating that the tone experienced by the group of rats just before each of 20 shocks was a reliable predictor of the shock for the first group.
The psychologist Robert Rescorla stated in his famous classical conditioning experiment that 2 stimuli does not produce the same level and kind of conditioning. Conditioning works in a better way, if the conditioned stimulus will act as a reliable signal that projects the appearance of an unconditioned stimulus.

<span>These gestures are known as emblems. An emblem is a gesture that conveys a specific non-verbal meaning that is understood by members of a particular culture or sub-culture. Unlike general shows of kindness such as smiling, emblems have specific meanings within specific contexts. Thumbs up for example may mean something specific in the United States, but will mean something completely different in Germany or other parts of the world.</span>
