Earth's atmosphere helps to regulate its temperature. However, the addition of gases such as
causes more energy to radiate back
toward Earth. As a result, the atmospheric temperature increases over time.
If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun. This implies that the temperatures on Earth would
be
Earth's current temperature.
Answer:
Carbon dioxide; lower than.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.
Earth’s atmosphere helps to regulate its temperature. However, the addition of gases such as carbon dioxide causes more energy to radiate back toward Earth. As a result, the atmospheric temperature increases over time. If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun.

draw a ppunnett sqare using the allele symbol H amd h to show the expected genotypes of the man and women biological children.
The Punnett square is used to make predictions about the genotype and phenotype of a future generation according to the alleles involved in the cross. 25% HH, 50% Hh, 25% hh.
What is a Punnett square?The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Let us assume that in the exposed example both parents are heter0zyg0us for the trait.
The feature is coded by a single diallelic gene in which H is the dominante allele and h the recessive allele.
Cross:
Parentals) Hh x Hh
Gametes) H h H h
Punnett square) H h
H HH Hh
h Hh hh
F1) Genotype
- 1/4 = 25% of the progeny is expeted to be h0m0zyg0us dominant, HH
- 2/4 = 1/2 = 50% of the progeny is expected to be heter0zyg0us, Hh

is the insect respiratory system more or less effective compared to the human respiratory system?
I'd say more effective.
"Insects have a more efficient respiratory system than humans. "
But at the same time insects don't have any lungs they breathe through the help of trachea/tubes/and or holes along their abdomen area.
You need to think about how small, compared to us humans, and insect is. They can take in a lot more oxygen than we can (for their size)
If we were to be able to shrink until we're the same size as an insect, they would be the ones taking in way more oxygen because of the way their system is constructed.

How does nuclear envelope aide in compartmentalization
The nuclear envelope distinct the process of transcription and translation in the cell. It controls the release of mRNA from the nucleus through the biological process of transcription.
What is a Nuclear envelope?A nuclear envelope may be characterized as a positively regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells.
The process of transcription occurs inside the nucleus and transforms DNA into mRNA, while the process of translation occurs in the cytoplasm which transforms mRNA to specific protiens.

Answer:
it is D
i am pretty sure
Explanation:
plants use the solar energy from the sun to be able to make chemical energy to synthesis their food( this process is called photosynthesis)
The climate changes on Earth tend to be self-amplified. For example, the Earth is currently going through a warming trend. As the Earth’s temperature rises, the ice caps and sea ice melt, reflecting less solar radiation. This results in more absorption of the Sun’s heat, causing the Earth’s temperature to rise more, and the ice to melt more. This is an example of what type of system?

Answer:
The Green Revolution involved the widespread use of chemicals in agriculture that had adverse environmental impacts. The interrelationships between water resources, erosion, pesticides and fertilizers, deforestation, population pressure, and biodiversity, and farmers are individually addressed.
Explanation:
The development of agriculture and the green revolution affected humans by increasing food production. However, it also led to environmental degradation.
What is green revolution?The development of agriculture provided humans with a stable food supply and allowed for the growth of civilizations. It also led to the domestication of animals and the creation of farming communities. The Green Revolution, which began in the mid-20th century, involved the development and implementation of new agricultural technologies and increased the productivity of crops, leading to increased food production and economic growth in many countries.
However, the use of pesticides and fertilizers in agriculture has had negative impacts on the environment, including soil degradation, water pollution, and loss of biodiversity. The Green Revolution also resulted in the increased use of mechanized farming, which led to the loss of natural habitats and the displacement of wildlife.
Climate change caused by agricultural practices, such as deforestation, and the use of fossil fuels in farming, has also had a significant impact on the environment.
