Would extraterrestrial life on other Earth-like planets look similar to organisms found here on Earth?

Answers

Answer: I don't think they would since all the planets we know have completely different conditions than ours.

Explanation:

Depends on the biosphere of the other planet, any living thing on another planet would adapt to that planets resources, atmosphere, and climate. SO if that planet was almost identical to ours then maybe? We still have to factor in speed of evolution and whether or not they are put through the same events or big changes that earth life has been put through. I hope this helps!

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?

Answers

Answer:

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.

Explanation:

Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.

The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.

Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.

A two-word name for organisms where the first word is the species and the second word is the genus

Answers

Answer:

A two-word name for organisms where the word is the genus and the second word is the species

Explanation:

Binomial nomenclature is the system biologists use to name species of living beings. When we translate this term, we get the two-name naming system. This tells us a lot about how species are named - their name consists of two components. The first component is the name of the genus the species belongs to and the second is the name of the species. For example, the scientific name used for cats is Felis catus. Felis is the genus and the species is catus.

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.

Answers

The box would stay at rest where it lies since the same amount of force is pulling it in opposite directions :)

Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.

What are balanced forces?

Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.

Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.

An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.

While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.

Therefore the correct option is D.

The ground had a light dusting of white sand over an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste.

The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds.
