A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns.
a. gene modification
b. artificial selection
A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.
What is gene modification?Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology.
Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.
For example, cornstarch can be made with GMO corn and sugar can be made with GMO sugar beets. Corn: Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides.
Therefore, A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.

and
How do you think the formation of fossils in sedimentary rock disrupts or alters the process of sedimentary rock formation? In other words, how does the formation of a fossil fit into the process of sedimentary rock formation? Defend your answer.
Answer:
I can't help sorry
Explanation:
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

Color is everywhere in nature. The arrows in the image model the wavelengths of visible light. Compare how the incoming colors of light behave when they encounter the kittens black fur, it’s white fur, the green grass, and the yellow dandelion
Answer:
The black color absorbs all colors of light, the white reflects all colors of light, the yellow-orange flowers only reflect yellow and orange light, and the green grass only reflects green light. It is because they reflect certain colors of light that these objects display certain colors.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun again?
A technique to change the game to make it play fairly and fun again is to deflate the ball in an attempt make it less bouncy.
Discussion:
A characteristic of the baseball game is that the baseball is less bouncy in comparison to other sports like football and basketball.
When the baseball game is played on the moon with a less gravity; the ball tends to ascend more as the force of gravity is lower compared to that of the earth.
Ultimately, lowering the air pressure in the baseball makes the ball less bouncy and the game may become fun to play again.

After Michelle went on vacation for two weeks, she came home to find her potted plants had turned brown and died. The soil was very dry. While Michelle was away, she kept the curtains and windows closed and did not have a neighbor come by to water her plants.

Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy.
Describe each object that you hit and the sound it made.
Rank the ten objects from loudest to softest.
Make some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?
Stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.
What is sound?Sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them. A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates through an elastic material medium.
The vibration of items creates sound, which travels from one place to another through a medium. Vibration is the phrase used to describe an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.
Thus, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

1. The strength of the gravitational force between two objects depends on which of the following?
o the mass of the larger object
the velocities of the objects
the orbits of the objects
o the mass of the objects and the distance between them
Answer:
D
Explanation:
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
Answer:
Newton's law likewise expresses that the strength of gravity between any two items relies upon two factors: the majority of the articles and the distance between them. Articles with more prominent mass have a more grounded power of gravity between them.
