The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication. ... Seedless plants multiply by spores that may produced asexually or as a consequence of asexual reproduction.
Gymnosperms. Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones.

Explain the different motions of Earth and how they cause days, years and seasons.
Answers
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.

Which of the following would provide the most energy in an ecosystem?
A. Omnivore
B. Carnivore
C. Producers
D. Herbivores
Answers
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.

Explanation: (1) Light energy and chemical energy should be switched. (2) Chemical energy should be changed to mechanical energy
Explanation:
Answer:Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

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.

Two models of molecules are shown. Two models of molecules. One on left is made of one carbon and one oxygen atom. One on right is made of one carbon and two oxygen atoms. What is true about the molecules shown in the models? A. They are molecules of the same substance. B. They are molecules of two substances with the same properties. C. They are molecules that join together. D. They are molecules containing the same kind of atoms.
Answers
Answer/Explanation:
CO and CO2 are both carbon poisoning. They both are odorless, colorless, and potentially deadly. But the chemical difference(extra oxygen molecule) causes it to be a different substance. CO is carbon monoxide while CO2 is carbon dioxide. CO2 is common because it is what we exhale after a breath, it is used to keep plants alive. On the other hand CO is caused by gas emissions and lack of oxygen. They may sound the same but they are just two different molecules containing the same types of atoms.

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
Answers
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.
