Identify the error that occurred in Meiosis II.A)Homologous chromosomes failed to separate, resulting in polyploidy.
B)Homologous chromosomes failed to separate, resulting in recombination.
C)Homologous chromosomes failed to separate, resulting in nondisjunction.
D)Homologous chromosomes failed to separate, resulting in independent
assortment
Identify the error that occurred in Meiosis II. A)Homologous chromosomes - 1

Answers

Answer 1
Answer:

Answer:

The correct option is C) Homologous chromosomes failed to separate, resulting in non-disjunction.

Explanation:

Non- disjunction can be described as a phenomenon in which the chromosomes fail to separate during cell division, resulting in both the chromosomes being transferred to a single gamete.

Non- disjunction can occur in three types:

  1. Non- disjunction can occur at the time of meiosis when the sister homologous chromosomes fail to separate.
  2. It might occur in mitosis when sister chromatids fail to separate.
  3. It might occur in meiosis II when sister chromatids fail to separate.

True or false the more variables you can test in an experiment the better the results

Answers

  never ever!!!!! if you have multiple independents you will never know which one(s) changed your dependent...dude who already answered.... don't just guess!!!!!
True, because then you have a broader view of the results. In other words, the majority of more variables is better than less variables. 

According to “Past Climate Changes on Earth,” what changes to the atmosphere caused temperatures to increase, making the Eocene such a warm time in Earth’s history?

Answers

Answer:

The most important factor was the accumulation of greenhouse gases, especially methane and  carbon dioxide.

Explanation:

The Eocene climate began with warming climate at 56 million years ago (Mya) and finalized at around 49 Mya ago. It is believed that during this period the greenhouse gases increased the temperature on the Earth's surface. This hypothesis is supported by evidence that indicates the melting of the ice cap in the poles.

Final answer:

During the Eocene epoch, high levels of greenhouse gases like carbon dioxide caused a strong greenhouse effect and warmed the Earth's climate. Increased volcanic activity is one possible source of these gases. The continents' position also contributed to the warmer temperature by modifying ocean currents.

Explanation:

The Eocene epoch was characterized by significantly warmer global temperatures than today. This climate change occurred due to elevated levels of greenhouse gases in the Earth's atmosphere. One of the primary gases was carbon dioxide (CO2),  possibly released by widespread volcanic activity. High levels of these gases trapped heat from the sun's rays within the atmosphere, a phenomena known as the greenhouse effect. Another contributing factor was the configuration of the continents, which amplified ocean currents' warming effect.
