Answer:
a, b, and d are the correct answers
Explanation:
Photosynthesis is the process in which plants produce their food as well as food for other organisms. Thus, options A, B and D are correct.
What is photosynthesis?Photosynthesis involves the conversion of light energy into chemical energy by plants.
Plants carry out photosynthesis in the presence of sunlight. They take up water and carbon dioxide to produce glucose and release molecular oxygen in the atmosphere.
This glucose is a six carbon sugar which can then be utilized to produce other carbon rich macromolecules.
Photosynthesis take place in the chloroplasts of the plant leaves.
Plant leaves contain green coloured chlorophyll pigment which traps the solar energy.
Only the green plants and some special bacteria carry out photosynthesis as chlorophyll is the reaction centre for photosynthesis.
Temperature, Light, moisture and carbon dioxide concentration are some of the factors that affect the rate of photosynthesis.
Therefore, photosynthesis is a prime event through which animals obtain their food and oxygen.

Answer: meristematic
Explanation:
Growth occurs throughout the plant's life, a process known as indeterminate growth. This indeterminate growth is possible because, unlike animals, plants have perpetually undifferentiated tissues called meristems. Read about plant meristems.

what base is found in mRNA but not DNA?
Answer:
Uracil
Explanation:
DNA has the nitrogenous bases of thymine, adenine, guanine, and cytosine.
In mRNA, however, the base called uracil replaces thymine.
mRNA has the bases uracil, adenine, guanine, and cytosine.
So, uracil is the base found in mRNA and not DNA.
The base that is found in mRNA but not DNA is uracil (U) and play a unique role in the synthesis of proteins.
What are nucleotide bases?Nucleotide bases are the building blocks of DNA and RNA, which are the genetic materials of living organisms. There are four nucleotide bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U).
These nucleotide bases are arranged in a specific sequence in DNA and RNA, which provides the instructions for building proteins and performing other functions in the cell. The sequence of nucleotide bases determines the genetic information that is passed from one generation to the next.
The nucleotide bases are connected by covalent bonds to a sugar molecule and a phosphate group, forming a nucleotide. Nucleotides are joined together by covalent bonds to form a chain, which is the structure of DNA and RNA. The sequence of nucleotide bases in DNA and RNA plays a central role in the storage and expression of genetic information.

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.
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.

How can landforms affect weather??
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.
Arrange the processes of the water cycle in the correct order, starting with the heat from the Sun.

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

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
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.
