Answer
Environmental pressures
Basically every animal adapts to pressures from their environment in different ways, causing them to have different shapes and sizes
Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.
The answer is B The new cell will have from each parent
Answer:
Outer, middle and inner layer.
Explanation:
Major Ocular Structures
The eye is made up of three layers: the outer layer called the fibrous tunic, which consists of the sclera and the cornea; the middle layer responsible for nourishment, called the vascular tunic, which consists of the iris, the choroid, and the ciliary body; and the inner layer of photoreceptors and neurons called the nervous tunic, which consists of the retina.
Factors affecting photosynthesis
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the rate of photosynthesis.
A graph with rate of photosynthesis on the y axis and light intensity on the x axis. The plotted line rises steeply and then levels off to horizontal.
Carbon dioxide concentration
Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.
A graph with rate of photosynthesis on the y axis and light intensity on the x axis. The plotted line rise steeply and then levels off to horizonal. During the steep part light is the limiting factor. During the horizontal part another factor has become limiting.
TemperatureIf it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.
A graph with rate of photosynthesis on the y axis and carbon dioxide concentration on the x axis. The plotted line rise steeply and then levels off to horizonal. During the steep part carobn dioxide is the limiting factor. During the horizontal part another factor has become limiting.
If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones shown above.
In practice, any one of these factors could limit the rate of photosynthesis.
