This Venn diagram is being used to compare the characteristics of nonvascular and vascular plants.



Which characteristic is shared by the two plants, and can therefore be placed in the overlapping section?

have roots
perform photosynthesis
have xylem and phloem
produce seeds

Answers

Answer:

perform photosynthesis

The specific xylem and phloem tissues that vascular plants (tracheophytes) have for supporting and conducting water and food, respectively, set them apart from nonvascular bryophytes.Thus, option B is correct.

What best defines about nonvascular and vascular plants?

The existence of chloroplasts and the green pigment chlorophyll, which enable plants to carry out photosynthesis, is the fundamental similarity between these two plant groupings. Due to their capacity to manufacture their own food, plants are now the main contributors to the ecosystem's production.

Tracheophytes are another name for vascular plants. Pteridophytes, gymnosperms, and angiosperms are among them.Nonvascular plants lack the specialized vascular system required to transmit water and nutrients. Examples of simple structures that are specialized for doing transportation are those found in algae and bryophytes.

Therefore, perform photosynthesis characteristic is shared by the two plants.

How can landforms affect weather??

Answers

Answer:

hope it helps! love uuwu

Explanation:

These effects can cause huge changes in the temperature, precipitation, and humidity of a region. An example is when a storm encounters a mountain range. The clouds can not go over the mountains, so the upwind side receives plentiful rainfall while the downwind side gets little to no rain

Huge bodies of water absorbs and releases heat in a very slow cycle. ... This causes a large difference in temperature at night and day on land or around bodies of water. This constant heating and cooling affects wind and rain. Role of landforms to global temperature and weather.

A student conducts an experiment where he places a light source below a plant. Over a three week time period he observes the plant's growth. Which of the following would he observe at the end of the three weeks.

Answers

Answer:

This question lacks options, the options are:

A). Roots would grow up out of the pot and then down towards the light.

B). The plant stem would grow up and roots would grow down.

C). The plant would start to bend over and grow downwards toward the light.

D). The plant would wilt and die.

The answer is C

Explanation:

This question is describing an experiment conducted to test the effect of LIGHT on plants movement, a phenomenon called PHOTOTROPISM. Phototropism is the response of a plant towards a light source.

According to this experiment, a light source is placed below a plant and observed over a three-week time period. At the end of three weeks, the experimenter will observe that "the plant would start to bend over and grow downwards toward the light" because the plants strictly require light to photosynthesize and grow, hence, it will respond by moving in the direction of the available light source.

The growth and the development of the plant parts towards the stimuli  source are called tropism. The plant will bend downwards towards the light source.

What is phototropism?

Phototropism is the phenomenon in which the parts of the organisms turns and starts growing in the direction of light sources like the sun or artificial light that acts as the external stimuli.

In the experiment, the light source acts as stimuli for the plant and the plant growth is the response. In the experiment the light source is kept down and acts as a stimulus for the plant, in return, the plant bends over and grows in the downwards direction.

Therefore, option C. plant will bend over and grow downwards.

What is the relationship between force, mass, and motion?

Answers

Answer: If an object is accelerating, then Force = Mass x Acceleration. If it is moving at a constant speed, then Kinetic Energy = 1/2 mass x velocity squared but in this case, there is no force acting on the object. Perhaps this will help understand the relationship between force and mass. Force is anything that acts on an object, from a person pushing on something to gravity holding the Earth in orbit around the Sun, to cause it to change speed or direction. If there is no change in speed or direction, then no force is acting on it. This relates to mass in the following way. THE GREATER THE MASS, THE GREATER THE FORCE NEEDED TO MAKE THAT MASS CHANGE SPEED OR DIRECTION. Think of it like this; what takes more force to push up a hill, a car, or a bicycle. The bicycle has less mass and therefore requires less force to push it.

Force = Mass x Acceleration if an object is accelerating.

What is Motion?

Kinetic Energy = 1/2 mass x velocity squared if it is moving at a constant pace, yet there is no force acting on the item in this scenario.

This will make the connection between force and mass more clear. Any action that exerts force on an object—from a person pushing something to gravity keeping the Earth in its orbit around the Sun—to change its speed or direction is referred to as force.

No force is acting on something if there is no change in its direction or speed. The following is how this relates to mass. The force required to cause a mass to change speed or direction increases with mass.

Therefore, Force = Mass x Acceleration if an object is accelerating.

Hawaii Coastal Cliffs are amongst the tallest cliffs in the world. What causes their formation? (image 2 with a bunch of water)

Based on the pattern of Erosion seen in these images, describe the causes of their formation. (image 3)

Answers

Answer:

(image 1) Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. As waves attack the shore, headlands are eroded, producing steep sea cliffs. The waves vigorously attack the portion of the cliff near sea level where joints, fissures, and softer strata are especially vulnerable. The cliffs are undermined and caves are formed. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

1.  Snapdragons can be red (RR), white (WW), or pink (RW).   Cross a red snapdragon with a pink snapdragon.  Give the genotype and phenotype percentages. 

Answers

Answer:

RR (hom0zygous dominant) - 50%

RW (heterozygous) - 50%

Red flower - 50 %

Pink flower - 50%

Explanation:

To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.

      R    R

R    RR  RR

W  RW  RW

50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.
