During mitosis, a double-stranded chromosome is attached to a spindle fibre at the:
A centriole. B centrosome. C centromere. D chromatid.
Why are there two copies of each chromosome? Question 5 options: One copy comes from each parent Chromosomes were duplicated in mitosis The chromosomes copied themselves through DNA replication
Answer:
One copy comes from each parent
Explanation:
The correct answer would be that one copy comes from each parent.
During gamete formation, the chromosome number in the sex cells is usually halved to produce haploid gametes. Haploid gametes fuse together and donate their chromosomes to form a diploid zygote during the fertilization process. Hence, one copy of the two chromosomes in diploid organisms comes from each parent.
Which is the process used by the cell to rid itself of unwanted, large substances?
exocytosis
active transport
passive transport
endocytosis
Answer:
Exocytosis is the reverse of endocytosis. Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.

Which of the following would provide the most energy in an ecosystem?
A. Omnivore
B. Carnivore
C. Producers
D. Herbivores
Answer:
The one that would provide the most energy in an ecosystem are producers!
Explanation: On the food chain and in the ecosystem they contain the most energy. About 90% is lost through heat and and movement of the animals. Lets say you have 10,000 kelo calories, then you have the producer and then your 3 animals, this means the last one only gets 10 kelo calories!
The following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.
What is the significance of the producers in energy production?Producers include plants, algae, and some bacteria that serve as the primary source of energy, converting light or chemical energy into a form of food such as glucose, and in every ecosystem, the producers have many important roles. Herbivores and carnivores all depend on them, both directly and indirectly.
Hence, the following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.

Explain the different motions of Earth and how they cause days, years and seasons.
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun).
hope it helps
Answer:
The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial precession).
Explanation:
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun). Seasons are largely due to factors surrounding the Earth's tilted axis as it revolves around the sun. A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly.

What are tectonic plates?Tectonic plates defined as the plates present inside the earth and the movement of tectonic plates causes earthquake. A volcano is a mountain or it is an open portion in a planet or crust of the moon from which molten rock, warm gases, and materials emitt. It is a landform where molten rocks erupt through the surface of the planet and volcano moutains open downwards to molten rocks.
According, to Geologists there are mainly four types of volcanoes and these are lava domes, shield volcanoes, composite volcanoes, and cinder cones. The main reason in the formation of volcanoes are movement of tectonic plates it means when one tectonic plate show movement under another tectonic plate formation of volcano takes place.
Therefore, Iceland is situated on a boundary where two plates are moving away from each other. Heat from Earth’s interior rises through this plate boundary at a fast speed. This fact makes Iceland which is suited to producing electricity using its abundance of geothermal energy.

Explain the process of how the Earth's layers became differentiated.
Answer:
The differentiation, or organization, of the Earth into layers is perhaps the most significant event in its history. It led to the formation of a core, a crust, and eventually continents.
