Why was Robert Brown unable to work out that water particles were making pollen move?
Robert Brown observed the erratic movement of pollen grains under a microscope, which he attributed to either heat or agitation. Because he did not witness the same movements in non-living particles, he concluded that the motion was due to some intrinsic property of living organisms rather than external factors like water particles.
What else can I help you with?
Sound waves are unable to travel through?
vacuum because they require a medium to propagate, such as air or water. In a vacuum, there are no particles for the sound waves to interact with and travel through, resulting in silence.
A refrigerator does not cool the food inside it properly if the food is too tightly packed?
When food is tightly packed in a refrigerator, the airflow is restricted, making it difficult for the cold air to circulate evenly. This can lead to uneven cooling and pockets of warm air where food may spoil faster. To ensure proper cooling, it's important to leave space between items for air to flow freely.
When Heat convection occurs in gases and liquids heat conviction does not occur in solids because solids are unable to?
In solids, heat conduction is the primary mode of heat transfer because the particles are closely packed and cannot move freely like in liquids and gases. This restricts the transfer of heat through convection, which relies on the movement of the fluid particles.
Which state of matter is least likely to transfer heat by convection?
The solid state of matter is least likely to transfer heat by convection because the particles in solids are closely packed together and do not move around easily to create the required fluid motion for convection.
Matter is made of tiny particles and these particles are always moving then why do objects such as a table a cup not move?
There are three types of matter; solid matter, liquid matter and gas matter. They are all made up of particles which are the building blocks of matter. Particles in a Gas matter are randomly separated, they are a bit far apart form each other, so they are able to move around efficiently. Particles in liquid matter are less separated from each other, they are closer to each, so there degree of mobility is limited. Particles in solid matter are packed close together and rigity and immobile. A table and a cup and objects of the types are solid matter so they are unable to move around.
How do particles with the same charge interact?
Particles with the same charge will interact by electrostatic repulsion.
What are rats unable to do making them extra unable to poisen?
they can't vomit..
Why rain occurs?
Rain occurs when droplets of water condensed on floating particles in the sky condense too much water, making the particle unable to float, so that the drop falls from the sky.
When did Robert Carter appear in Bonanza?
I was unable to find Robert (Bob) Carter on the guest star list of the series.
What is the main purpose of a bee's wings?
To allow it to fly. Without this ability it would be unable to pollinate plants or collect nectar and pollen.
What happens when pollen of a rose plant reaches the stigma of a carnation flower?
If pollen from a rose plant reaches the stigma of a carnation flower, fertilization is not likely to occur. Compatibility between different plant species is low due to genetic differences. This will likely result in the pollen not being able to germinate and grow to fertilize the ovules of the carnation flower.
You know bees can transfer pollen but can bats do the same?
Yes, actually bats can transfer pollen from one plant to another. The plants depend on bees, bats, and butterflies to do this because they are unable to move.
What would happen to a cell if its channel proteins where damaged and unable to transport particles?
they die
What are the characteristics of a sterile flower and how does it impact the reproductive process of the plant?
A sterile flower lacks the ability to produce viable pollen or ovules, making it unable to participate in the plant's reproductive process. This can hinder pollination and fertilization, ultimately reducing the plant's ability to produce seeds and reproduce.
Why particles in solid unable to move freely?
particles in solids are unable to move freely because the atoms that makes up the solid are tightly packed together. the molecular structure of a solid is different to that of a liquid or a gas.
What does drought affect?
a drought is where there is no rainfall for a long period of time making vegetation unable to grow and animals unable to survive. :)
