Answer:
Alcanos, alquenos y alquinos.
Explicación:
Los hidrocarburos se forman con la unión de los elementos carbono e hidrógeno, hay tres grandes grupos de hidrocarburos que son alcanos, alquenos y alquinos. Estos hidrocarburos se dividen en grupos según el tipo de enlace. Los alcanos son los hidrocarburos que contienen enlaces simples entre átomos de carbono, los alquenos tienen un doble enlace entre átomos de carbono, mientras que los alquinos contienen un triple enlace carbono-carbono.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.
Genotype
Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green
84%
F (dominant)
Dark green plumage
ff
White
16%
f (recessive)
White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)
Group of answer choices
The student needs the percent of the population with the Ff genotype in order to find the F frequency.
Her research advisor would first want her to find the males' mating success rate for the calculations.
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.
Answer:
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Explanation:
A group of scientists are studying the genome of the Drosophila Fly. In these flies, the allele for long wings is dominant over the allele for short wings. What phenotype would a heterozygous genotype have?
Answer:
Long wings dominant = LL
Short wings recessive = ss
Heterozygous= Ls

Do plants produce more oxygen than they need?
Answer:
Photosynthesis uses carbon dioxide to make sugar and produces oxygen as a byproduct. Respiration uses oxygen to release energy from stored sugar and produces carbon dioxide as a byproduct. ... However, if the plants are growing, then over a period of 24 hours they will produce more oxygen than they consume.

What does coal do to the environment
Answer:
the burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.Explanation:
Answer: Burning fuel releases CO2 into the atmosphere these gasses are called greenhouse gasses. When enough of these gasses accumulate in the sky the earth's natural temperature increases.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

How do cancer cells differ from normal cells? Select all that apply.
A
they do not stop at checkpoints
B
they condense their DNA into chromosomes for cell division
C
they have uncontrolled growth
D
they go through the S phase
Answer: A and B
Explanation:
Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth. So, options A and C are correct.
What do you mean by Cancerous cells?Cancerous cells may be defined as an abnormal cell that doesn't follow the regulations of the cell cycle. They get multiply at a rapid speed.
Normal cells follow a typical cell cycle. They grow, divide and finally die. But cancer cells do not follow the cell cycle, they do not undergo apoptosis, and they continuously multiply at a rapid pace.
Therefore, Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth.
