In which organelle can most of the DNA be found In eukaryotic cells?
A. the Golgi bodies
B. the ribosomes
C. the mitochondria
D. the nucleus
The DNA from each parent is housed in the cell nucleus and is utilized to direct cellular activity and define inherited features. Hence option D is correct.
What is DNA?DNA stands for deoxyribonucleic acid. It is defined as a sophisticated molecule that carries all the data required to create and maintain a creature. All known living things, including many viruses, need DNA, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce.
In terms of genomics, a nucleus is the organelle within a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules into and out of the nucleus.
Thus, the DNA from each parent is housed in the cell nucleus and is utilized to direct cellular activity and define inherited features. Hence option D is correct.

how do physical characteristics of organisms support the theory of evolution?
Answer:
Homologous features
Explanation:
If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Answer:Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

Brainlist What causes water to condense on top of an aircraft's wing?
High pressure on front of wing forces water to condense.
Slower moving air on top of wing causes lower air pressure, cooling air.
Faster moving air on top of wing causes lower air pressure, cooling air.
Low pressure on the front of the wing causes water to condense.
Answer:
As the pressure above the wing, reduces, there is a sudden fall in temperature of the air above the wing. This sudden drop in air temperature, condenses the water vapor present in the atmosphere, above the wings. So, then the condensation clouds are formed above the wings.

Using the diagram above, answer the following questions: True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected? Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
(1)The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. (2) The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false . Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. (3) The arrow C represents the emission of carbondioxide in the atmosphere. As you can see that the arrow is from the smoke that is emitted from the factories and industries and to the carbondioxide in the atmosphere. (4) arrow E (5) I think it would be the sun because it’s the one giving energy to most things, and if you haven’t answered it yet you can put the sun because it’s giving energy to the plans and the environment and it’s the the sun was the effect of the whole thing, sorry if I didn’t help

how do you find out if something is alive or dead?
Answer:
In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.
Which is one characteristic of deep ocean currents?
Deep ocean currents move quickly.
Deep ocean currents are caused by winds.
Deep ocean currents move cold water toward the equator.
Deep ocean currents are affected by temperature but not by salinity.
Answer: Deep ocean currents are affected by temperature but not by salinity.
Explanation: I think it's this because I know it takes a while for deep ocean currents to move so it isn't the first one.
The characteristic of deep ocean currents is that deep ocean currents move cold water toward the equator.
The ocean currents can be defined as the continuous movement of seawater bodies in the ocean.These ocean currents move due to different forces that act upon the seawater body.The deep ocean currents occur in high latitude areas (e.g., Antarctic Bottom Water, North Atlantic Deep Water, etc) and move cold water toward the low latitudes (i.e., the Equator).In conclusion, the characteristic of deep ocean currents is that deep ocean currents move cold water toward the equator.

What is Hippo?
The hippopotamus, also known as the hippos, hippopotamuses, or hippopotami (Hippopotamus amphibius), is a big semi-aquatic mammal that is indigenous to sub-Saharan Africa. It is sometimes referred to as the common hippopotamus, Nile hippopotamus, or river hippopotamus.
The hippopotamus is the largest terrestrial mammal after elephants and rhinos. Additionally, it is the largest living land artiodactyl.
The closest surviving relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from whom they separated some 55 million years ago, despite their morphological resemblance to pigs and other terrestrial even-toed ungulates.
Therefore, Number 4 about the river-horse is a hippo. River-horse is Greek for hippo.
