Following crossover, the homologous chromosomes split, then in Meiosis II, sister chromatids split. The condition that would result is deletion

During the process of meiosis, a pair of similar chromosomes go through a process called crossing over, or recombination. This process means that genetic material is swapped between the chromosomes. Sometimes, during the process of crossing over, it can happen in an imbalanced way and cause unequal crossing over.

Unequal crossing over can cause one part of the genetic material to be lost from one side and duplicated on the other side. In this situation, chromatid C would show the part of the genetic material that has been removed. So, a deletion would happen in the final gamete.

The anatomist cuts the cadaver with a large saw in a way that divides it into equal left and right halves along the sagittal plane.

The sagittal plane is one of the three primary anatomical planes, along with the frontal (coronal) plane and transverse (horizontal) plane. The sagittal plane divides the body or an organ into left and right halves.

When an anatomist cuts a cadaver or a preserved body along a plane that divides it into equal left and right halves, it is specifically referred to as a "sagittal plane" cut.

The term "sagittal" is derived from the Latin word "sagitta," which means "arrow."

The sagittal plane is named as such because an imaginary arrow passing through the body from front to back would be aligned with this plane.

By making a sagittal plane cut, anatomists can examine and study the internal structures of the body or organs in a symmetrical manner, allowing for comparisons and analysis of the corresponding structures on both sides of the body.

Greenhouse gases are substances that trap heat within earth’s atmosphere. This statement provided is true.

The greenhouse effect is a natural process that plays a vital role in regulating the Earth's temperature. When sunlight reaches the Earth's surface, it warms the planet. Some of this heat is then radiated back into space as infrared radiation. However, certain gases in the atmosphere, known as greenhouse gases, have the ability to absorb and re-emit this infrared radiation.

Greenhouse gases act like a blanket or a greenhouse, allowing sunlight to enter the Earth's atmosphere and reach the surface. When the Earth's surface absorbs this sunlight, it warms up and emits infrared radiation. Greenhouse gases present in the atmosphere absorb a portion of this outgoing infrared radiation and re-emit it in all directions, including back towards the Earth's surface. This process traps some of the heat within the atmosphere, preventing it from escaping into space and causing the planet to warm.

Without the greenhouse effect, the Earth would be much colder, making it difficult to sustain life as we know it. However, human activities, particularly the burning of fossil fuels (such as coal, oil, and natural gas) and deforestation, have significantly increased the concentrations of greenhouse gases in the atmosphere. This increase in greenhouse gases has enhanced the greenhouse effect and led to an increase in global temperatures, a phenomenon known as anthropogenic climate change or global warming.
