The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.
Explanation:
In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".
Answer:
3 yellow : 1 green
Explanation:
Let yellow seed trait be represented by Y allele and green seed trait by y allele.
Purebred yellow seed plant = YY
Purebred green seed plant = yy
YY x yy = Yy, Yy, Yy, Yy (all yellow)
This thus means that yellow seed trait is dominant over green seed trait.
F1 x F1 = Yy x Yy, resulting in YY, Yy, Yy, yy offspring.
Since Y is dominant over y,
YY, Yy, Yy = Yellow
yy = green
<em>Hence, the expected phenotypic ratio of seed color of the offspring of F1 x F1 cross is </em><em>3 yellow : 1 green</em>

Answer:
experiments can be designed and performed by anyone with a curious mind
Explanation:
baking soda and vinegar explosions are an experiment that doesnt require expensive equipment
always do more then one trial, like shooting a basketball, if you shoot once and miss, can you say that you will never make it? or if you make it, can you say that you will never miss?
variables are what you are testing, you have to eliminate as many as possible so they dont effect your experiment
if you have any questions, leave them in the coments and i will try to answer them, if this helped, pls give brainliest.
