Answer:
Vascular plants are successful due to better transportation for water, nutrients and reproduction.
Explanation:
I got it right at school and hope this helps you learn to STUDY.jk
According to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:
Sperm can be more effectively and widely distributed for sexual reproduction, thanks to pollen grains.Vascular plants can reproduce without the need for a moist environment because they can make pollen grains.What are Pollen grains?Plants with seeds, including flowering plants and conifers, produce pollen grains as a component of their reproductive process. They are often carried by wind or pollinators, such as bees, to the female reproductive organs of the same or different plant species, where they can fertilize female gametes (egg cells) and begin the development of seeds.
They carry the male gametes (sperm cells) of the plant. Many plant species depend on pollen grains for successful reproduction, and these grains have evolved a variety of forms, sizes, and surface features that make them easier to disperse and be recognized by pollinators.
Therefore, according to scientists, the evolution of pollinators made vascular plants the most successful land plants for two major reasons:
Sperm can be more effectively and widely distributed for sexual reproduction, thanks to pollen grains.Vascular plants can reproduce without the need for a moist environment because they can make pollen grains.Learn more about Pollen grains, here:

In order for radiation to transfer heat, electromagnetic waves must be transmitted objects must be in direct physical contact particles must circulate and move in a liquid or gas thermal energy must move from cold to hot objects
I don't really know if this is chemistry, but help please!!! Very urgent!!
Answer: is A Radiation is a type of heat transfer that transfer heat by electromagnetic waves. Outside the visual color range, we cannot see it. But sure almost everything is emitting and absorbing radiation right now. This type of heat transfer works in almost every environment, including vacuum.
Explanation: I hoped that helped.
In order for electromagnetic radiation to transfer heat the objects must be in in direct physical contact.
What is electromagnetic radiation?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

What is the opposite force to pushing off the ground to jump?
Answer:
Newton's Third Law of Motion states that to every action there is an equal and opposite reaction. When the earth pushes on you to send you into the air after jumping, you also push on the earth with the same force. But forces are different from accelerations. A force F is a push or pull on an object

We can verify the properties as follows;
1) Sour taste - Put some soda on your tongue
2) Corrode metals - Put a little soda on a clean metal surface
3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

In ecosystem, particles are carried as bed load by rubbing particles together.Path of stream can be varied depending on amount of humus present in soil and is measured in cubic meters per second and carrying capacity depends on type of material through which stream flows.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
