Answer:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

What is carbon cycle?Carbon cycles through Earth's atmosphere, oceans, land, and living things. Carbon is essential to numerous life-sustaining chemical processes. Carbon dioxide (CO2), which plants use for photosynthesis and regulates Earth's temperature, is in the atmosphere.
Several Earth processes transport carbon between reservoirs in the carbon cycle. Photosynthesis, respiration, and decomposition. Plants employ photosynthesis to convert CO2 into organic carbon molecules like sugars for growth. Plants and animals respire to release CO2 into the atmosphere. Decomposition by microorganisms releases CO2 from dead plants and animals.
The carbon cycle is a crucial aspect of Earth's climate system, regulated by CO2 levels, photosynthesis and respiration rates, and greenhouse gas levels. Understanding the carbon cycle helps us comprehend climate change and identify solutions.

What is the difference between surface ozone and the ozone layer?
Answer:
How does the ozone layer differ from ozone at the surface of the earth?
Ozone molecules (O3) have three oxygen atoms. Ozone is found in two different layers in Earth's atmosphere. "Bad" ozone is found in the troposphere, the layer nearest the ground. ... Ozone in the stratosphere forms when a photon of ultraviolet "light" from the Sun strikes a normal oxygen molecule, breaking it apart.
