Q3. A student investigates factors that affect photosynthesis. (a) In his first experiment, the student uses this method to investigate the effect of light on photosynthesis. place a plant in the dark for 24 hours cover part of leaf X with black paper place the plant in the light for 24 hours The diagram shows the plant in the light.​

If you could weigh a sealed air bag before and after it inflates, the weight would increase and decrease. this is a property of a  matter.

A property is a structural characteristic of a system that is independent of the system's size or the volume of its constituent parts.

Volume and internal energy are extensive qualities while density, pressure, and temperature are intensive ones.

Temperature, T, refractive index, n, density, and object hardness are a few examples of intensive attributes, these are  all physical characteristics of matter fit within those categories.

C. The angle of the sun's rays and the number of hours of daylight.

The length of daylight hours and the angle at which the sun's rays hit the Earth's surface both have a big impact on the seasons. The Earth's axis is tilted in relation to its orbital plane as it revolves around the sun.

Because of this tilt, various areas of the Earth's surface get sunlight at varying angles throughout the year. When one hemisphere is inclined towards the sun, more direct sunlight falls there, resulting in longer daylight hours and higher temperatures, giving rise to summer.

Function is an exponential growth function or exponential decay function  it is an exponential decay function, as it starts at infinity and ends at 0.

For exponential functions, we see that our end behavior goes to infinity as our input values get larger. The larger the base of our exponential function, the faster the growth. For logarithmic functions, our function grows slowly as our input values get larger.

Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments, to mention a few. Any quantity that grows or decays by a fixed percent at regular intervals is said to possess exponential growth or exponential decay.

Based on the shape of the exponential decay graph, we have the following end behavior: As , x → − ∞ , . y → ∞ . As , x → ∞.

The gizzard is the muscular organ located between the crop and the small intestine in birds. Its primary function is to mechanically grind and break down food, as birds do not have teeth to chew their food.

The gizzard accomplishes this through strong muscular contractions that crush and grind the food against small stones and grit that the bird has ingested.

Therefore, it is likely that the contents found in the gizzard would be more ground up compared to those found in the crop. The crop is a storage organ located at the base of the bird's neck that serves as a temporary holding place for food before it enters the digestive system. While the crop may soften and partially break down food through the secretion of digestive enzymes, it does not have the same mechanical grinding function as the gizzard.

In summary, the gizzard is the organ responsible for grinding and breaking down food in birds, while the crop primarily serves as a temporary storage organ. Therefore, the contents found in the gizzard are likely to be more ground up compared to those found in the crop.

From the diagram, circuit a and b are series circuit while c is parallel. Option C

The components in a parallel circuit are linked together so that the electric current can go along several different routes. The power source is directly connected to each component, forming parallel branches. While the current in a parallel circuit can vary, the voltage between each component is constant.

The components of a series circuit are connected one after the other to create a single path for the passage of electricity. While the voltage across each component can change, the current flowing through each component is constant.

i belive it is B. oxygen and carbon dioxide

Plants use carbon dioxide for photosynthesis and oxygen is a product of photosynthesis.

The two gases that plants must exchange with the air are oxygen and carbon dioxide. Oxygen is required for respiration while carbon dioxide is required for photosynthesis. The exchange of these gases is essential for the survival of plants and for maintaining the balance of gases in the atmosphere. Option B)

The two gases that plants must exchange with the air are oxygen and carbon dioxide. Plants consume carbon dioxide during photosynthesis and release oxygen back into the atmosphere. This process of photosynthesis occurs in the chloroplasts of the leaves and involves the absorption of sunlight and conversion of carbon dioxide and water into glucose and oxygen.
In the process of respiration, plants use oxygen to break down glucose and release energy. The waste product of respiration is carbon dioxide, which is released back into the atmosphere. This exchange of gases is vital for the survival of plants as well as for maintaining the balance of gases in the atmosphere.
Oxygen is important for the survival of all living organisms, including plants. It is required for respiration, which is the process of releasing energy from food. Carbon dioxide, on the other hand, is a waste product of respiration and is required for photosynthesis. The exchange of these two gases between plants and the atmosphere is essential for the survival of both. Therefore option B) is correct.

Explanation:

Answer:

The treatments will be the group of mussels Mytilus californianus placed in an environment similar to low tide and the group of mussels Mytilus californianus placed in environments similar to high tide. As well as the group formed by Mytilus trossulus mussels placed in an environment similar to low tide and the group of Mytilus trossulus mussels placed in an environment similar to high tide.

The number of replicates in each group must be at least 64 for each treatment.

Explanation:

In an experiment, treatments are the groups of elements that will be tested. As in the above experiment, two groups of different mussels will be investigated in two different environments, we will need one group of each mussel in each environment, so there will be 4 treatments.

In addition, it is necessary to know the number of replicates that the treatment must have, which allows a reasonable number of degrees of freedom to be obtained at the time of the statistical analysis. To know the minimum number of replicates you should consider the expression n^3, where "n" represents the number of treatments. In this case, the expression will represent 4^3 which will give a total of 64 replicates.

The skin is a selective barrier, which protects the human body from any type of external attack, among its functions is not releasing digestive enzymes.

It is an integument that is made up of an outer layer (called the epidermis) and an inner layer (called the dermis).

Water

Explanation:

This looks like a proverbial question, so I'll try and answer it as best as I can

Th mixture of 'hydrogen and oxygen came pouring out' to give water. Water is a liquid that 'drips and dribbles and it comes poring from a spout'

The question is talking about the reaction between hydrogen and oxygen to give water; a form of liquid as the by-product.

The reaction involves one atom of oxygen reacting with two atoms of hydrogen with an hydrogen bonding in-between to give a molecule of water.

Also note that a spout is a stream of liquid issuing from somewhere with great force. So the answer is water.
