Explanation:
The example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.
The stimuli are the things or events that causes the detectable change in the organism. The reaction of the organism with response to the stimuli is measured in terms of sensitivity.
What is a stimulus response?The stimulus response is created when the external event or the thing brings changes in the chemical or physical nature. The response to stimuli are instant reactions.
The decrease in the pupil size with the light as the stimulus is the response of eyes.
Thus, the example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.

cuticle - epidermis - palisade mesophyll - spongy mesophyll- epidermis - cuticle
What is a cuticle and what does it do?The cuticle is widely known for its roles as a diffusion barrier limiting water and solute transport across the apoplast and for protecting the plant from mechanical and chemical damage, pest and disease attack, as well as these other threats.
What function does the plant epidermis serve?The protective tissue known as the epidermis covers the entire plant's surface and shields the beneath tissues from harm.
What are spongy mesophyll and palisade?Palisade mesophyll and spongy mesophyll are the two forms of mesophyll cells found in dicotyledonous leaves. Spongy mesophyll cells are internal to the lower epidermis, whereas palisade mesophyll cells are elongate and form a layer beneath the upper epidermis.learn more about layers of cells in leaf here https://brainly.com/question/13929978

Which of the following best supports the theory of continental drift?
A
South America and Africa have completely different rock layers.
B
A hurricane hits the Gulf of Mexico at the beginning of June.
C
Similar fossils are found on the coasts of South America and Africa.
D
North America and South America are connected by land.
Answer:
C
Similar fossils are found on the coasts of South America and Africa.
Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.
The correct answer is:
Option C. Similar fossils are found on the coasts of South America and Africa.
The explanation for the correct answer is:
The continents either drifted away or clashed together to form present-day continents.Remains from similar species infer that South America and Africa used to be together.The theory of Pangaea states that all the continents were united once but due to a shift in tectonic plates the continents drifted apart.Therefore, alike fossils found in various continents supports the theory of continental drift.

10) When gravity acts upon inertia will an object go straight or curve? Why?
Answer: Inertia is the tendency of an object to resist motion
Inertia is simply the tendency of an objects to resist a change in whatever state of motion that it currently has. Put another way, inertia is the tendency of an object to "keep on doing what it is doing." Mass is a measure of an object's inertia.

When the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.
What is Earth rotation?Earth's rotation or Earth's spin is defined as the rotation of the planet Earth around its axis as well as the change in the orientation of the axis of rotation in space. When viewed from Polaris, the north pole star, the Earth rotates in the east facing east, the Earth rotates counterclockwise.
When the heading of the particular place is towards the Sun, there is warm temperature which is called as the summer when the heading of the same place is away from the Sun, there is cold temperature which is called as the winter.
Thus, when the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

1. green renewable fuel immediately reduces transport carbon emissions to zero
Answer:
Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.
Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?
A. There are variations in their RNA sequences.
B. The leaves and flowers show morphological differences.
C.They produce viable but sterile offspring.
D.They occupy unique habitats in an ecosystem. .
Answer:
the answer is C
Explanation:
Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.
The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.The biological concept of species states that mating between individuals of the same species produces viable offspring.The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

What is the process represented by this diagram
Answer:
Photosynthesis
Explanation:
The process described in the image attached to the question above is PHOTOSYNTHESIS, which is the metabolic process whereby plant cells manufacture their own food in the presence of a light source (sunlight) for energy. Photosynthesis occurs in the chloroplast of plant and algae cells.
Photosynthesis occurs in two stages namely; light-dependent stage and light-independent stage. The light dependent stage synthesizes ATP and NADPH molecules needed by the next stage to produce sugars.
According to the image portrayed in this question;
- Letter A represents the LIGHT ENERGY source.
- Letter B represents WATER while K represents OXYGEN gas given off
- Letter F represents thylakoid lumen where the first stage occurs while letter G represents the stroma of the chloroplast where second stage occurs.
- Letter C represents carbon dioxide (CO2) while letter L represents glucose molecule.
