Answer:
The options are unclear but the answer is 8^2π square feet or 64π sqfeet
Explanation:
Area of a circle is denoted by: πr^2 where r is the radius of the circle.
In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2
= 16/2 = 8 feet.
Thus, the radius = 8 feet.
Hence, Area of a circle = πr^2
= π × 8^2
= 64π or 8^2π sqfeet.
Answer:
The answer is A.
Explanation:
Since only 1 of the options is wrong, i assume you are looking for that one.
Two types of immunity systems, innate immunity and adaptive immunity. Adaptive immunity is formed when it is exposed to a harmful substance, vaccines for example create adaptive immunity.
Innate immunity is present at birth which consists our skin protects us physically, chemical substances in our blood that protect us from bacteria and infections and also our blood cells such as T cells.
Since innate immunity forms one of the first lines of defense in our immune system and is the first to respond to a threat in a few hours down to as little as minutes, it is not slower than adaptive immunity in its response to infections and pathogens.
I hope this answer helps.
Answer: In meiosis I, homologous chromosomes partitioned, whereas in meiosis II, sister chromatids isolated. Meiosis II produces 4 haploid girl cells, though Meiosis I produces 2 diploid girl cells. Hereditary recombination (crossing over) as it were happens in meiosis I.
Explanation:
Rain occurs because of moisture gathering higher in the atmosphere. The process that creates rain in the atmosphere has a variety of steps we don't see. This process is called the water cycle. This cycle is never ending, meaning that rain is a constant on the earth as long as there's an ocean or water on the earth.
Water vapor is an atmospheric moisture that is sometimes visible to the naked eye. Water vapor comes in the form of clouds, fog, mist, and dew. The process that creates water vapor is called evaporation, which is where water on the earth is heated to a temperature that makes water molecules spread out and begin to vibrate quicker. This creates water vapor.
The water vapor is commonly carried high into the atmosphere to create clouds. Once the vapor is in the atmosphere, it begins to lower in temperature. This causes condensation, which means the water vapor is reforming into water droplets.
Precipitation Takes place after this. Precipitation occurs when the water droplets are too heavy to carry in the atmosphere, so they drop back down to the earth. After this takes place, the entire process resets, and happens again.

Answer;
D. Meiosis ii of mother
Explanation;
-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.
-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
