Describe how the amount of light influences the rate of photosynthesis
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
What is the valence number of the
following atoms; carbon, nitrogen, oxygen, phosphorus and hydrogen?
Answer:
C = 4
N = 5
P = 5
O = 6
H = 1
Explanation:
Valence number is the number of valence electron of an atom. It can be count through electronic configuration of an atom.
Oxygen is present in group 18.
Its atomic number is 8.
Electronic configuration:
O₈ = 1s² 2s² 2p⁴
In valence shell (2s² 2p⁴) there are six electron thus valence number of oxygen is six.
Carbon is present in group 14.
its atomic number is 6.
Electronic configuration:
C₆ = 1s² 2s² 2p²
In valence shell (2s² 2p²) there are four electron thus valence number of carbon is four.
Nitrogen is present in group 15.
Its atomic number is 7.
Electronic configuration:
N₇ = 1s² 2s² 2p³
In valence shell (2s² 2p³) there are five electron thus valence number of nitrogen is five.
Phosphorus is present in group 15.
Its atomic number is 15.
Electronic configuration:
P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³
In valence shell (3s² 3p³) there are five electron thus valence number of phosphorus is five.
Hydrogen is present in group 1.
Its atomic number is one.
H₁ = 1s¹
Its valance number is 1.
explain three ways in which red blood cells are adapted to their function
Answer:
Red blood cells are adapted to their function by:
1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.
2) They are small and flexible so that they can fit through narrow blood vessels.
3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.
Hope this helps! :D
Describe what happens to the air in the lungs when we breathe. What happens to the concentration of
carbon dioxide and to the concentration of oxygen?
When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.
Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.
Hope this helped, even if it helped a tiny bit. :)

How do nucleic acids and carbohydrates interact?
Explanation:
When living beings eat, fats, carbohydrates, proteins, and nucleic acids are all absorbed. Protein-rich foods and their constituent amino acids are also rich in nucleic acids because cells in protein-rich foods have been actively involved in protein synthesis when the food was harvested. Tofu, soybeans, meat, poultry, fish, legumes (peas and beans), root vegetables, and dairy products are high-protein foods, which are also rich in nucleic acids.

Which phrase describes the best area to dig down to the groundwater?
A: where the saturated zone is 15 meters deep
B: where the water table is at 100 meters deep
C: where the unsaturated zone is 50 meters thick
D: where there is a 25-meter thick clay layer at the surface
Answer:
If the saturated zone is 15 meters deep, that area is the best to dig down so its A.
Explanation:
The saturated zone is the area under the ground where the water is stored in tiny spaces between rock, soil, sand, and gravel.
The water in this region flows freely through the pores within the geologic medium.
Most people dig a hole to insert pipes until this region identified with water for the purpose of boring and building wells.
These regions can be found after digging above hundred feet or just below the ground surface.
The phrase that describes the best area to dig down to the groundwater is where the saturated zone is 15 meters deep. The correct option is A.
What is groundwater?Water that is found in soil, rock, and rock formation fissures below the surface of the Earth is known as groundwater.
In the saturated zone, which is located below the surface, water is held in minuscule crevices between rocks, soil, sand, and gravel. In this area, the pores of the geologic media allow water to flow freely.
For the purpose of digging and building wells, most people dig a hole and place pipes into it until the area is filled with water. These areas can be reached by drilling a few feet or more below the surface of the ground.
Therefore, the correct option is A: where the saturated zone is 15 meters deep.

What is the your groundbreaking idea for a razor or hair removal product that awakens your senses?
Answer:
hope it helps you
Explanation:
Traditionally, shaving and hair removal brands provide mainly functional benefits: they get the job done, but they don’t deliver an enriching, self-care experience. Their products aren’t going to uplift you or make you feel calm and relaxed. Instead, they offer mundane experiences and boring designs and scents.
As a leading personal care brand, we are looking for razor and shave preparation ideas that will make shaving enjoyable, that are experiential, and that stimulate the senses (olfactory, tactile, vision, etc.). We are looking for creative solutions that will appeal to those who love variety, who enjoy exploring new things, and who value enriching experiences. Personal care should give us a chance to reground ourselves, awaken our senses, and feel better in our day-to-day.
We are interested in groundbreaking ideas for wet-shave devices (e.g. razors) and/or packaging that will awaken your senses without compromising the effectiveness or durability of the products.
Your idea could improve the sensory shaving experience at any level. Primarily, we are looking for ideas that relate to razors, but we are also open to shave preparation (pre, during, post shaving) as well as packaging. In proposing your idea(s), please consider the following:
Be creative! Feel free to go beyond scents / olfactory experience.
Bring ideas for razors, shave preparation, pre-shaving and post-shaving.
Women should be the target demographic for your product idea. Please be sure your idea has feminine appeal.
Your idea should be feasible for high-volume production (think about processing conditions and high speed manufacturing).
Your product idea should be able to survive in the typical “bathroom” / usage environment of a razor. Think of the shower, where there is high humidity, exposure to chemicals from other products, etc.
Please include any references or background information related to your proposed material sources. We want to understand what inspired your idea and review any relevant sources that support it!
Begin by answering the survey questions below.
Gifts on buying of products and scent in the products are the ideas that increases the sale of the product.
My groundbreaking idea for a razor or hair removal product is that the razor or hair removal product companies has to provide gifts on the buying of their products. This type of strategy will definitely increases the sales of their products.
The other groundbreaking idea is to make these products with a scent that refreshes the mind of the user. In this way the people will like the product and increase the sales of these products so we can conclude that gifts on buying and scent in the products are the ideas that increases the sale of the product.

Cacti typically have spines instead of leaves . The stem of a cactus is green , which indicates that it contains a chemical that is stored in a particular organelle . What is the name of the chemical in the stem of a cacti ? What organelle is the chemical stored in?
Answer:
Chlorophyll
Chloroplast
Explanation:
Chlorophyll is a pigment found in the chloroplast organelle of certain organisms including plants, algae etc. Chlorophyll is the reason plants and certain algae are able to perform photosynthesis because chlorophyll pigment helps them capture light energy from the sun.
According to this question, a xerophytic plant called CACTUS, is being described to possess a chemical in one of its organelle that makes it seem green in appearance. That chemical is CHLOROPHYLL, with chemical formula, C₅₅H₇₂O₅N₄Mg. It is found in the CHLOROPLAST organelle as stated earlier and makes the stem of cactus and other plants green because it reflects green light and absorbs other colour of light. This makes organisms that possess chlorophyll appear GREEN.
