Instead of seeds, seedless plants produce cells called Spores
2.Seedless plants can be organized into two groups called pteridophytes and Bryophytes
3. Bryophtes are also called Nonvascular plants
4. Pteridophytes are also called Vascular plants.
Explanation:
Seedless plants can be organized into two groups called Pteridophytes and Bryophytes. Bryophytes are also called nonvascular plants and Pteridophytes are also called vascular plants.
What are Bryophytes?Bryophytes are also known as amphibians plants because they need water to achieve se-xual reproduction.
Bryophytes are non-vascular plants because they lack vascular tissues. Pteridophytes are called vascular cryptogams because the means of reproduction are sometimes hidden.In conclusion, seedless plants can be organized into two groups called Pteridophytes and Bryophytes. Bryophytes are also called nonvascular plants and Pteridophytes are also called vascular plants.

What is photosynthesis.
Answer:
Photosynthesis:
Photosynthesis is the synthesis of food(glucose) from water and carbon dioxide in the presence of sunlight and chlorophyll.
Chemical Reaction:

Transport O2 and nutrients throughout the body Remove waste products found within the body Move blood to the lungs from the left side of the heart Move blood systemically from the right side of the heart Release of oxygen through the gastrointestinal tract via the splanchnic circulation
Answer:
Transport O₂ and nutrients throughout the body
Remove waste products found within the body
Explanation:
The circulatory system performs the function of transporting oxygen and nutrients to the cells. It also helps in removing the wastes from these cells. The circulatory system involves blood, blood vessels, arteries, veins, and capillaries. From the lungs, the oxygen is carried to all parts of the cells. The waste product, carbon dioxide, is carried to the lungs. The nutrients are carried from the small intestine and delivered to all the cells of the body.

Which of the following is NOT one of the three global wind patterns?
A. Polar Easterlies
B. Westerlies
C. Trade Winds
D. Interglacial Winds
Answer:
I believe that the correct answer is d. Interglacial Winds
Explanation:
Please mark as brainiest ! Hope this helps!
Polar Easterlies, Westerlies and trade winds are the three main global wind patterns. Interglacial winds are not a type of global wind patterns. Thus, the correct option is D.
What are global wind patterns?Global Wind Patterns is mainly the result of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the planet earth. Warm air around the equator is lifted that creates a suction effect for air masses coming from different latitudes.
The three important global wind belts are polar easterlies, westerlies, and trade winds. The polar easterlies flow from the north and south poles towards 60° north and south, respectively. They are very cold and dry winds. The westerlies are present between 30° and 60° north and south of the Equator.
Therefore, the correct option is D.

Explanation:
Kala added a spoon of yeast and hot boiling water to knead bread dough, whereas Rupa added warm water to knead the dough with yeast in it. Both of them made bread. Whose bread will be soft? Why?
Answer:
I think Rupa's bread will come out softer than Kala's.
Explanation:
Using hot boiling water to activate yeast can kill it. Instead of being absorbed by the protein, the hot water is absorbed into the starch molecules.
It is better to use warm water to get a more fluffy bread.
Soft bread is soft because CO2 produced by yeast and water that gets turned to steam by the baking process gets trapped into pockets by a mesh of gluten, causing the dough to expand. The dough then solidifies, keeping its shape. If your bread is not soft then it hasn't expanded enough for one or more reasons.

Answer:
The correct choice would be: "The data supports the hypothesis because when annual temperature deviations are below normal, the annual number of hurricanes increases."
Explanation:
The large discrepancies between temperatures due to global warming promote the appearance of hurcanaes, that is, the greenhouse effect and pollution encourage the appearance of excessive thermal amplitude and this helps the appearance of hurricanes.
What are the 3 kinds of helpful social behavior?

the things that plants need to grow are;
1. proper sunlight : it is very important for plants to get proper sunlight because if they dont get proper amount of sunlighr they maynot be able to manufacture food and grow too.
2. proper nutrition: it is also an important factor to grow the plants.
3. sufficient amount of water: it is also essential factor because if there is no water they cannot make food and if no food they cannot grow.

In which scenario does Newton's cradle have the most potential energy? A. Newton's cradle has the most potential energy right before it stops moving and all the kinetic energy has been converted to potential energy. B. Newton's cradle has the most potential energy when the end ball is lifted to its maximum height before being released. C. Newton's cradle has the most potential energy when the balls are moving back and forth. D. Newton's cradle has the most potential energy when the balls are at rest.
Answer: Option D.
Newton's cradle has the most potential energy when the balls are at rest.
Explanation:
Newton's cradle demonstrate principle of conservation of momentum which states that when two objects collide, the total momentum before it's collision is the same as it's momentum after it collision.
Newton's cradle has the most potential energy when the balls are at rest because an object at rest or by virtue of it's position has potential energy when it's not moving or stationary. A stationary or objects at rest posses potential energy.
Potential energy is the energy posses by a body or object that is not moving or at rest or energy stored by an object by virtue of it's position.
The scenario where Newton's cradle has the most potential energy is Option D. i.e. when the balls are at rest.
What is the principle of conservation of momentum?It should arise at the time when the two objects should be colliding here the total momentum prior to the collision should be similar just like the momentum after the collision. The cradle of the newton should occur the most potential energy at the time when the ball should be at the rest since when the object should be at rest. Also, the stationary and the object should be at rest when it possessed the potential energy.

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes where does it occur?.
Answer:
Two processes were described in this question, hence, the location of the two processes are as follows:
synthesize energy-rich organic molecules- CHLOROPLAST
Break them down to extract energy- MITOCHONDRIA
Explanation:
Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.
However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.
