By looking at a plant, how can you tell if it is a cycad and not a palm?
A. look for pollen
B. look for leaves
C. look for roots
D. look for cones

Answers

Answer 1

Answer: Look for the cones

Explanation: I took the test and I got it correct.

Answer 2

Cycads are non flowering plants and palms are flowering plants . Therefore, option (D) look for cones.

What are palms and cycads ?

Gymnosperms known as cycads are characterised by their massive, pinnately complex leaf crowns and their cones, which are usually carried at the end of the trunk in the middle of whorled branches. Others have partially submerged stems with inflated (tuberous) trunks and tall, unbranched trunks that resemble armor.

There are three different types of palm tree leaves, known as fronds: fans, feathers, and whole leaves. Typically green, palm tree fronds can have a range of textures, such as waxy, smooth, matte, etc.

In gymnosperms, a leafy green sporophyte produces cones with male and female gametophytes. Female cones are larger and higher up the tree. Male gametophytes (pollen) are produced in male cone microsporophylls and carried by wind to female gametophytes.

Therefore, option (D) is correct about palms and cycad.

Then decide whether to add of subtract, as the whole purpose of this method is to eliminate a variable. The x was eliminated. Then you can solve to get y.

Going back to one of the ORIGINAL equation, sub in your y and solve. Then you can put your x and y into an order pair (x,y). That pair is your answer!

Explain why the Moon, stars, and sun appear to change positions in the sky.

Answers

Answer:

because the earth rotates and revolves around a axis causing the stars sun move to change position and shape

The moon, stars, and sun appear to change positions in the sky because of the rotation of the earth on its axis, and due to the combination of the earth's rotation and its orbit around the sun, as well as the moon's orbit around the earth, their positions change.

What are the positions change of the moon, stars, and sun?

The Earth rotates on its axis once every 24 hours, causing the Sun, Moon, and stars to appear to move across the sky; this motion is caused by the Earth's rotation, and the position of the Sun in the sky also changes throughout the year due to the Earth's orbit around the Sun. As the Earth moves in its elliptical orbit, the angle of the Sun's light hitting the Earth changes, and the Moon appears to change positions in the sky because of its orbit around the Earth, so all three change positions.

Hence, the moon, stars, and sun appear to change positions in the sky because of the rotation of the earth on its axis.

combustion:

Answers

Answer:

The reaction in the diagram is right.

Explanation:

In complete combustion, hydrocarbon fuels burn in the presence of high concentration of oxygen that produces carbondioxide gas and water which are releases in the atmosphere. Complete combustion takes place only when there is oxygen present in large amount whereas incomplete combustion occurs when the oxygen in the environment is limited so complete combustion required more oxygen as compared to incomplete combustion.
