50% or 0.5 is the probability that the offspring will have a cleft chin.
Explanation:
Data given:
Cleft chin = dominant, genotype CC
one parent, heterozygous so genotype, Cc
other parent = no cleft chin, genotype is cc (recessive)
probability of child with cleft chin =?
The cross between the given genotype will be shown in punnet square:
C c
c Cc cc
c Cc cc
The results obtained from the cross shows that 50% chances of the progeny having cleft chin.
The phenotype ratio: cleft chin: no cleft chin
1:1
the genotype ratio of the progeny
heterozygous dominant : recessive homozygous
1:1
Hello! Allow me to help!
Your question: Can the atmosphere change in its composition?
My answer: Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.
Why is my answer correct? Good question! Allow me to explain: Tropical deforestation not only has a large impact on the carbon cycle and climate, but also affects the chemistry of the atmosphere. Together with the carbon cycle and weather patterns land use can affect the concentrations of greenhouse gases like methane and ozone.
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.

Answer:
The argument can be contradicted by assuming that both animals and fungi exhibit heterotrophy and have intracellular spindles.
Explanation:
If an argument is required to demonstrate that fungi have common characteristics, it can be taken into account that:
- <em>They are</em><em> heterotrophic organisms</em><em>, since they are not able to synthesize their own nutrients, such as plants.
</em>
- <em>Both </em><em>have intracellular spindles</em><em> in their structure, useful when performing the corresponding cell division.
</em>
- <em>Additionally, both animals and fungi can </em><em>store glycogen</em><em> as a reserve of energetic substrate.</em>
It is currently thought that fungi and animals have a convergent or parallel evolution.
