In humans, if a non-disjunction event led to an individual with a genotype of XXY, they would be male because they have a Y chromosome.
What are X and Y chromosomes?The X chromosome and Y chromosome are homo-logous chromosomes that determine the se_x in mammals.
The presence of the Y chromosome is indicative of the males, whereas two X chromosomes are females in normal conditions.
Non-disjuntion refers to the faulty separation of homo-logous chromosomes during meiosis.

What prior species of hominids did homo sapiens encounter in europe approximately 40,000 years ago?.
Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

Which of the following does water pollution affect: surface water, ground Water, or ocean water? A)Pollution affects surface water and ground water only.
B)Pollution affects surface water, ground water, and ocean water.
C)Pollution affects surface water and ocean water only.
D)Pollution affects groundwater and ocean water only.
Water pollution includes any kind of water masses or currents. Option B is correct. Pollution affects surface water, ground water, and ocean water.
What is water pollution?
Water pollution can be defined as the abnormal accumulation of strange elements in the water with harmful consequences to natural ecosystems.
Water pollution involves all the possible ways in which any water body can be contaminated with harmful elements.
The most damaging source of water pollution is human activities, producing the biggest damage to natural ecosystems.
Contaminating elements might be either gasses, solid material, or liquid material. Chemical elements, microbiota, heavy metals, and sediments affect all forms of life.
As said before, several sources can contaminate water masses, and they do it directly and indirectly.
Directly pollution occurs when a strange element is thrown directly into the water. They can be thrown directly into a river, a lake, the sea, or the ocean.
Indirect pollution occurs when pollutants travel from other places and contaminate other masses of water. For instance, a polluted river contaminates the lake where it ends. The lake pollutes the river that begins in the lake. This last river ends in the sea and takes all pollutants to the sea.
We can affirm then that water pollution affect surface water, ground water, or ocean water. Option B is correct. Pollution affects surface water, ground water, and ocean water.
