plants undergo both photosynthesis and respiration. which statement correctly compares photosynthesis with respiration?
Answer:
Oxygen and carbon dioxide
Explanation:
deficiency of nitrate ions in plants
Answer:
Plants absorb nitrates in water through their roots. ... Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

What are the advantages and disadvantages of seed and spore reproduction? Justify whether seed reproduction or spore reproduction is more beneficial for the continuation of an organism.
hi have a great day
No Water Required
Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.
Fully Developed Embryo
Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.
Nourishment
Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.
The Seed Coat
The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.

A student is conducting a breeding experiment. She knows the genotype of one parent plant and concludes that she can use a Punnett square to predict the outcome of crossing the plant with another plant. Which statement best explains why this conclusion is incorrect?
a. She needs to know the phenotypes of the previous plant generation.
b. She needs to know the phenotype of the first plant.
c. She needs to know the genotypes of the previous plant generation.
d. She needs to know the genotype of the second plant.
D. She needs to know the genotype of the second plant.
What is a punnett square?A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.
Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

exchange of gases in the human breathing system takes place in the?
alveoli
ExplanationDuring gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The exchange of gases takes place in the alveoli.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Additional information :- Alveoli are microscopic air sacs. They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Maggots get their energy by breaking down dead and decaying animals. What are maggots? autotrophs producers decomposers heterotrophs.
Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.
Maggots are:
Option C. Decomposers
This type of organism can be explained as:
The organism is classified into different classes according to the nature of its feeding habits.Autotrophs are called the primary producer and break inorganic compounds into organic for energy.Producers are the organism that produces their food by converting solar energy into chemical energy.Decomposers are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.Heterotrophs are organism that depends on other sources and producers for energy.Therefore, maggots are decomposers.

how is it possible that plants can express firefly genes?
Plants have the recessive firefly genes in their DNA. Proteins are engineered into genes in the DNA of other organisms. All organisms contain DNA and RNA.
If brown hair is dominant and red hair is recessive, what are the possible genotypes for Sally is she has brown hair?
Answer:
the answer is BB, Bb
Explanation:
If brown hair is dominant you need to consider the fact that it cant be bb otherwise she would have red hair because lowercase genotypes mean recessive. this eliminates the first and third answer leaving you with the second and fourth answer and we can eliminate the second answer because it says "what are the possible genotypes" meaning we need to list all the possible answers which leaves you with the fourth option.

1. Describe the structures of the chloroplast where photosynthesis takes place.
2. What would happen if the stomata of a plant leaf were glued shut? Would that plant
be able to perform photosynthesis? Why or why not?
3. What are the reactants needed to perform photosynthesis? The products?
4. What happens to the products of photosynthesis?
Answer:
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
The plant leaf would not be able to perform photosynthesis. The leaf needs to have its chloroplasts facing the sun, so that they can absorb the sunlight to perform photosynthesis.
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6). The oxygen will leave the plant through the stomata and enter Earth's atmosphere.Explanation:

quarterly (every 3 months) and the money is left for 7 years.
Answer:
you will have a negitative amount
Explanation:
so there is 12 mounths in a year divided by 3 is 4 then times by 7 is 28.
so then 9,100 times .065 is 591.5 that is how much mony goes in the 3 months. Then you do 28 x 591.5 =16562 so you wont have any money left you will actually be in the negitatives.
