Answer: In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.
Hope this helps!
Answer:
The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.

Which pair of microscope views represents a eukaryotic cell and a prokaryotic cell?
Answer:
They can both be unicellular and multicellular
Explanation:
The difference between the two microscope views of an eukaryotic cell and a prokaryotic cell is that the eukaryotic cell appears to have a distinct nucleus and other organelles when viewed with a light microscope, whereas the prokaryotes do not.
What is the difference between eukaryotes and prokaryotes?Eukaryotic cells have a distinct nucleus and other membrane-bound organelles, while these are absent in the prokaryotic cells, and the prokaryotic cells are smaller in size than eukaryotic cells due to the lack of organelles.
Hence, the difference between the two microscope views of an eukaryotic cell and a prokaryotic cell is that the eukaryotic cell appears to have a distinct nucleus and other organelles when viewed with a light microscope, whereas the prokaryotes do not.

Answer:
Mutualism.
Explanation:
The bacteria lives in the human intestine and get food from the person while on the other hand, the person gets vitamins that the bacteria produce by consuming food, this type of relationship is known as Mutualism because in this relationship both gets benefit from one another. Mutualism is a symbiotic association in which both the organisms gets benefit from each other.

Which of the following is a MECHANICAL wave vibration? * O Sound waves O Light waves O Radio waves O Reflection
Answer:
An example of vibration by mechanical waves is sound waves.
Explanation:
Mechanical waves are those capable of transmitting energy, which can propagate in the same direction, resulting in an alteration of the mechanical properties of a material. As a result of this, the material presents changes in the energy of its atoms and molecules.
Sound waves are mechanical waves, which require a medium for transmission and act as elastic waves capable of propagating longitudinally, producing a vibration.
Sound propagates and can produce waves in water or vibrations that reach the eardrum and enable the reception of this sound.
The other options are not correct, because light and radio waves are electromagnetic waves that are transmitted in a vacuum, without producing vibrations. Reflection is a property of light.

A car is traveling 5 m/s North, its displacement is
after 9 seconds?
Given parameters:
Velocity of the car = 5m/s North
Time = 9s
Unknown:
Displacement of the car = ?
Solution:
Displacement is the distance traveled in a specific direction. It is a vector quantity with magnitude and direction.
To find displacement use the expression below;
Displacement = Velocity x Time
Input the parameters and solve;
Displacement = 5 x 9 = 45m due North
The displacement of the car is 45m due North

what is active transport and what does it require?
Answer:
An active transport is the movement, requiring energy, of ions or molecules across a membrane into a region of higher concentration.
Memory technique:
To help you remember the difference between active and passive energy, think of being active, like playing football or jumping rope. All these things require energy, just like an active transport. Passive transport does NOT require energy.

Ocean trenches are formed when oceanic plate cools and moves to the surface of the ocean.
Ocean trenches are formed when the denser oceanic late sinks.
Ocean trenches are formed when molten rock cools and solidifies.
Ocean trenches are formed when magma accumulates on the ocean floor.
Answer:
Ocean trenches are formed when the denser oceanic plates sink.
Explanation:
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

Atoms of which three elements could bond together to form an organic compound?
a. oxygen, iron, and carbon
b. carbon, hydrogen, and oxygen
c. oxygen, hydrogen, and nitrogen
d. carbon, iron, and nitrogen
Answer:
Hello!!! Princess Sakura here ^^
Explanation:
It's B because organic compounds are molecules that contain carbon atoms bonded to hydrogen atoms and choice B is the only one that has both.
The three elements carbon, hydrogen, and oxygen make up more than 99 percent of organic compounds. Carbohydrates, lipids, and proteins are only a few of the chemical compounds that these three combine to create nearly all the chemical structures required for life.
What are the main constituents of an organic compound?Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements,
most frequently hydrogen, oxygen, or nitrogen. Carbides, carbonates, and cyanides are among the few carbon-containing substances that aren't categorized as organic.
Organic substances are made of carbon, hydrogen, and frequently oxygen or nitrogen. Given that they are linked to living things, organic chemicals are given that term.
