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.

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.

Answer: Abiotic processes synthesized small organic molecules, such as amino acids and nucleotides. These monomers were joined into polymers, including proteins and nucleic acids. Polymers were packaged into “protobionts,” droplets with membranes that maintained an internal chemistry distinct from their surroundings.

hello your question is incomplete below is the missing part

What is your velocity in miles per hour on your way to the gas

station? Hint: Remember that your starting point is 2 miles from your house to the North

answer : 10 miles/hour

Explanation:

Velocity = displacement / time

displacement = 2miles - 1 mile

time = 0.1 hour

velocity on way to gas = ( 2 - 1 ) / 0.1

                                     = 1 / 0.1 =  10 miles/hour

Answer: B, genetic simularities

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.

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.

Answer:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Answer:reproductive cells

Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

Answer:

The correct answer would be - natural active immunity.

Explanation:

Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.

If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.

In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.

(-1,-3) on the coordinate grid.

Explanation:

The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).

He walked 5 units south and met his friend Joshua.

So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).

Sam then walked 2 units east, where he met his friend, Ethan.

So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).

So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

Humans may acquire the disorder by eating diseased meat products. When it comes from cattle, the disorder is called Creutzfeldt-Jakob disease and ultimately leads to dementia and death. The condition is rare.

The disease is marked by rapid mental deterioration, usually within a few months. Most people eventually lapse into a coma.

Treatment focuses on keeping the person as comfortable as possible.

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.

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.

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.
