Which of the following scenarios of reproduction is most likely to form uniform offspring?
Pollen from one flower pollinates an egg of another flower to produce seeds.

Answer:
An amoeba splits during binary fission into two separate cells.
Explanation:
The amoeba have identical offspring while all others have genetic variences
The scenarios of reproduction which is most likely to form uniform offspring is an amoeba splits during binary fission into two separate cells. Thus, the correct option is D.
What is Reproduction?Reproduction is the process of formation of new organisms which are similar to the parent organism or parent cell. Reproduction is the process which generally occurs through different methods in a living cell or an organism.
Reproduction is mainly of two types, which include Asexual and Sexual mode of reproduction. Asexual reproduction is the reproduction where only one organism is involved in the process and it does not need the formation of gametes or the sex cells and sexual reproduction results into the formation of organisms through the fusion of gametes from two different organisms.
An example of asexual reproduction is an amoeba which splits through the binary fission into two separate new daughter cells.
Therefore, the correct option is D.

Why does sound bounce off of walls?
Answer:
Original sound waves are distorted by strong later-arriving reflections. Also, sound wave energy is really fast, about 1130 feet per second. A sound wave will bounce back and forth between these two walls about 60 times in one second. Sound travels so fast, it fills a room almost instantly.

How does earth's position in space affect water on earth?
Answer:
The Earth's position affects the water because the sunlight from the sun can impact the temperature of the water. It heats the water ethics and the land around it. When the Earth is facing the moon (nighttime), it cools the ocean creating a soft reaction.
Explanation:
While Earth orbits the sun, the planet is simultaneously spinning on an imaginary line called an axis that runs from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun.

A. Nucleus
B. Cell membrane
C. Cell wall
D. DNA/Genetic material
E. Ribosome
F. Lysosome
G. Chloroplast
Answer:
F. Lysosome
Explanation:
Lysosomes ,also called the 'Waste Disposals Of A Cell', are sac-like organelles that contain powerful digestive juices in them. They help in digesting worn out cells or foreign particles such as Toxins or Waste, that don't belong there. Their enzymes are so powerful that, when they burst [During a spontaneous change in cell metabolism], they digest the whole cell with them.
Does asexual reproduction involve the formation of gametes? Explain your answer
Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.
Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction, either from from a single cell or from a multicellular organism, inherit the genes of their single parent.
