Scientists need to learn to make arguments based on evidence. That means they back up their statements with facts that support them. Prokaryotes and eukaryotes look very different. Please make an argument based on evidence that they should both be considered cells anyways.
Answers
All complex life on Earth is eukaryotic. All eukaryotic cells share a common ancestor that arose just once in four billion years of evolution. Prokaryotes show no tendency to evolve greater morphological complexity, despite their metabolic virtuosity. Here I argue that the eukaryotic cell originated in a unique prokaryotic endosymbiosis, a singular event that transformed the selection pressures acting on both host and endosymbiont.
The combination of massive bioenergetic expansion, release from genome-size constraints, and high mutation rate favored a protosexual cell cycle and the accumulation of eukaryotic traits. These factors explain the unique origin of eukaryotes, the absence of true evolutionary intermediates, and the evolution of sex in eukaryotes but not prokaryotes.

The color of a planet provides clues to its composition. From space, much of Earth looks blue because most of its surface is covered with water. The surface of Mars is much different from that of Earth. Much of its surface is made up of iron oxide, or "rust." Which color would you expect Mars to be?
Answers
Answer:
Mars would have different variations of brown, red, and orange.
Explanation:
Since different places of Mars have different substances or have different "ages" the color will be different.
Rust is formed because iron reacts to different substances, so there might be different weather patterns around Mars, and hence different colors of the rocks, iron, etc.

maybe you should look up what erection/arousal is?
erosion is what happens to layers of the Earth such as rock over time
Answer:
When a male is aroused sexually, the blood vessels in the penis relax and open up, allowing blood to fill them. Blood trapped under high pressure creates an erection. Ejaculation is a reflex action controlled by the central nervous system.

NASA believes that technology drives exploration. This means that advancements in technology lead to advancements in space exploration. Over the past 60 years, we have developed technology to leave Earth's surface, orbit the planet, reach the Moon, take exceptional pictures of celestial objects, and complete remote fly-by's of outer planets. In the future, technology could lead us to visiting other planets, live and work in deep-space, or even leaving our own galaxy.
Select the statement(s) that illustrate why developing space technology is important.
Technology in space helps us in our everyday lives here on Earth.
Space exploration technology has helped us explore the Moon and see images of far off galaxies.
Technology allows us to better understand our world so that we can make it better.
Technology only helps scientists while they are doing experiments.

Stacy made the following table to compare the functions of plant and animal structures, but she is missing a row title. Which of the following would best replace the X?
a table comparing the functions of different animal and plant structures. There is an unknown 'X' in the table. The skeleton in animals and the stem in plants provide support. The fur in animals and the waxy covering in plants provide protection. The ovaries in animals and the pistil in plants make 'X'
Eggs
Fruit
Sperm
Food
Answers
All vertebrates are known to have two ovaries. Many invertebrates have testes and ovaries in a single animal. The ovaries in animals and the pistil in plants make eggs. The correct option is A.
What is pistil?The female reproductive structure of the flower is known as the pistil. It consists of the structures like stigma, style, ovary and ovule. The major function of the pistil is to support the pollination process which finally leads to fertilization.
The stigma of the pistil receives the pollen and the style transports the pollen to the ovule. Pistils protects the ovule present inside it. The ovary is also the female reproductive organ in which the sex cells are produced called an egg.
The function of the ovaries is to nurture the eggs for the process which is called the ovulation.
Thus the correct option is A.

Answer: The Shape of Molecules
The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. In order to represent such configurations on a two-dimensional surface (paper, blackboard or screen), we often use perspective drawings in which the direction of a bond is specified by the line connecting the bonded atoms. In most cases the focus of configuration is a carbon atom so the lines specifying bond directions will originate there. As defined in the diagram on the right, a simple straight line represents a bond lying approximately in the surface plane. The two bonds to substituents A in the structure on the left are of this kind. A wedge shaped bond is directed in front of this plane (thick end toward the viewer), as shown by the bond to substituent B; and a hatched bond is directed in back of the plane (away from the viewer), as shown by the bond to substituent D. Some texts and other sources may use a dashed bond in the same manner as we have defined the hatched bond, but this can be confusing because the dashed bond is often used to represent a partial bond (i.e. a covalent bond that is partially formed or partially broken). The following examples make use of this notation, and also illustrate the importance of including non-bonding valence shell electron pairs (colored blue) when viewing such configurations .
Methane Ammonia Water
Bonding configurations are readily predicted by valence-shell electron-pair repulsion theory, commonly referred to as VSEPR in most introductory chemistry texts. This simple model is based on the fact that electrons repel each other, and that it is reasonable to expect that the bonds and non-bonding valence electron pairs associated with a given atom will prefer to be as far apart as possible. The bonding configurations of carbon are easy to remember, since there are only three categories.

Explanation:
he diagram shows changes of state between solid, liquid, and gas. The atoms of a substance lose energy during a change of state. Before the change, the atoms are close together but are able to slide past one another.
A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
