which steps of the greenhouse effect are most affected by the increases in greenhouse gases, leading to increase in heat?
Answers
Answer: Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earth is sometimes called the “Goldilocks” planet – it’s not too hot, not too cold, and the conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

If DNA read A-T-T-A-C-G-G-C-C what would the RNA read? Why is DNA replication important?
Answers
If DNA read A-T-T-A-C-G-G-C-C the RNA would be U-A-A-U-G-C-C-G-G
DNA replication is important because new cells require their own strand of the DNA. Without replication, there would be no new organisms because the DNA’s information would not be passed on.

Answers
Answer:
Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to
What events cause exhalation?
Answers
Answer:
The process of exhalation occurs due to an elastic recoil of the lung tissue which causes a decrease in volume, resulting in increased pressure in comparison to the atmosphere; thus, air rushes out of the airway. There is no contraction of muscles during exhalation; it is considered a passive process.

Explanation:
Farmer Betty is famous for her winged pigs. Having wings (G) is dominant over not having wings (g). Farmer Betty mates a winged pig to one without wings (GG x gg) and all of the offspring are heterozygous (Gg). Do the heterozygous piglets have wings?
Question 7 options:
Half of them do
Yes, but just one
Yes
No
Answers
They all have wings because G is dominant. If there is one G it is dominant over g, and all the offspring are Gg.
In a heterozygous organism, the recessive trait is concealed by the dominant one. Option C is correct. All Heterozygous piglets have wings.
Law of inheritance:
When two pure parents are crossed, in the first generation all the offsprings will be heterozygous and show dominant character only.
In the Given scenario,
Winged pigs (G) are dominant over the non-winged pigs(g).
The cross is
(GG x gg)
In the F1 generation, all pigs are heterozygous.
Since all winged pigs are dominant over the non-winged pigs.
Therefore, Option C is correct. All Heterozygous piglets have wings.

What is the correct sequence of molecules involved in protein synthesis from beginning to end?
mRNA → tRNA → DNA → Protein
mRNA → tRNA → DNA → Protein
DNA → mRNA → tRNA → Protein
DNA → mRNA → tRNA → Protein
DNA → mRNA → Protein → tRNA
DNA → mRNA → Protein → tRNA
tRNA → Protein → mRNA → DNA
Answers
Answer:
DNA → mRNA → tRNA → Protein
DNA → mRNA → tRNA → Protein
Explanation:
This is because during protein synthesis, DNA is use to make RNA in the process called transcription. The DNA double strand is unwind by an enzyme called RNA polymerase to produce mRNA in the nucleus. The trans is produced in the nucleolus by RNA polymerase 1 and the site then binds aminoacyl tRNAs which is assembled in the RIBOSOMES. The tRNA are then translated into protein.

Rose conducted an experiment to study the effect of temperature change on the heart rate of Daphnia, transparent aquatic invertebrates commonly known as water fleas. She heated three different beakers of water containing Daphnia to a different temperature: 30°C, 32°C, and 34°C. She put a drop of water from each beaker on a slide mount and used a microscope to observe Daphnia in each sample. She counted the number of heartbeats in one minute and averaged her results. Which of the following could be a step in a replication of this experiment?
Answers
Answer:
Rose's classmate Mina observing Daphnia in water at 30°C, 32°C, and 34°C.
A step in replication of Rose's experiment could be to repeat the procedure of heating three different beakers of water containing Daphnia to 30°C, 32°C, and 34°C, counting the number of heartbeats in one minute for each sample using a microscope and slide mount, and averaging the results.
What is Daphnia?Daphnia, also known as water fleas, are small, transparent aquatic invertebrates that are commonly used in scientific experiments to study the effects of environmental factors on living organisms. In many experiments, Daphnia are subjected to changes in temperature, light, oxygen levels, and other variables to determine how these changes impact their behavior and physiology.
One example is studying the effect of temperature on heart rate, as done by Rose in the experiment described above. The use of Daphnia in experiments is beneficial because they are easy to culture, reproduce quickly, and are small and simple enough to be easily manipulated in the laboratory. Additionally, because Daphnia are freshwater organisms, they are particularly sensitive to changes in their environment, making them useful for investigating the impacts of various stressors on aquatic ecosystems.
