A plant that was grown in the dark continuously would: ________.

a. not be able to take in CO2 without sunlight.
b. remain healthy because plants have stored materials in their roots that can provide what the Calvin cycle needs.
c. not be able to split water to provide NADH.
d. continue to photosynthesize because to in carbon dioxide, the only outside input to the Calvin cycle, does not require sunlight.

Answers

Answer 1

Answer:

c. not be able to split water to provide NADH.

Explanation:

Photosynthesis, which is the process by which plant species obtain their energy, occurs in two stages viz: light dependent phase and light independent phase. The light dependent phase of photosynthesis requires the energy from sunlight, which is captured by the chlorophyll pigments in the leaves of the plant.

The light energy captured by the chlorophyll is used to split water molecule in a process called PHOTOLYSIS OF WATER. Overall, ATP and NADH (electron donor) are products of the light dependent stage, which enters the next stage to complete the photosynthetic process.

Therefore, a plant that was grown in the dark i.e. no access to light, continuously would not be able to capture light energy and hence not be able to split water to provide NADH.

Answer 2

A plant that was grown in the dark spontaneously would not possess the tendency to split water to provide NADH.

What is photolysis of water?

The process by which the species of plant attain their energy, that is, photosynthesis, takes place in two stages:

Light independent phaseLight dependent phase

In the light dependent phase, energy is needed from sunlight, and is captivated by the chlorophyll pigments present in the leaves of the plant. This energy from the light is used to split the molecule of water by a process known as photolysis of water.

The products of the light dependent stage is ATP and NADH that enters the next phase to complete the process of photosynthesis. Therefore, a plant, which was grown in the dark, that is, having no accessibility to light, would not possess the tendency to captivate the energy from the sunlight and thus would fail to split the molecule of water to provide NADH.

Thus, the correct answer is option c.

Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?


A. The light bends when it enters water due to its reflection.

B. The speed of light remains the same as it moves from air to water, causing the light to reflect.

C. The speed of light increases when it enters a different medium, but it doesn't bend.

D. The speed of light changes as it moves from air to water, causing the light to bend.

Answers

Answer:

D

Explanation:

Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.

The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.

The correct option is D.

An aquarium with a glass lid is an example of an isolated system.

Answers

Answer:

The answer is false!

Explanation:

I took the K12 science quiz.  I hope this helps! Have a blessed day! :)

The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.

What is an aquarium?

An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.

Aquariums are made up of glass, and they are open from the top so that fish can get air.

An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.

Therefore, the statement is false.

Explanation:

The most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

What is the significance of the geographical distribution?

It is significant because they differ in different parts of the world and provide suitable climatic and other environmental conditions for various animals, plants, and microorganisms to live and evolve. Its significance can be seen in the difference between the life forms in the temperate area and those in the Antarctic area.

The decline in approximately 70% of the world’s bird species is particularly alarming to scientists because ____ .

Answers

Answer:

See the answer below

Explanation:

The approximately 70% decline in the world's bird species is alarming to scientists because some species of birds have been found to be good indicators of the health status of the environment. Birds are generally easy to detect in an environment and the ability to fly away due to terrible conditions of habitat makes them a good indicator of the health of habitats or environment in general.

A 70% reduction in the species of birds worldwide is thus alarming due to the direct correlation that exists between the species diversity of birds and the health of the environment. It could presumably be an indication that about 70% of the world's habitat has been destroyed or impacted negatively.

The knee ________.
a. is completely enclosed by a strong articular capsule
b. is a multiaxial joint
c. has ligaments present inside as well as surrounding the articular capsule
d. is the simplest joint in the body

Answers

Answer:

The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.

Explanation:

The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.

Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).

The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.

The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.

The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.

three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle

Answers

Answer:  

-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)

-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)

-termite’s feces help to prevent erosion  

Explanation:

Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.
