Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.
Answer:
See the answer below
Explanation:
From the illustration of the experiment, the question that Carson can best answer is that "Do bananas develop more brown spots if they are kept in bags with holes compared to bags without holes?"
The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.
Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes.

Golden-cheeked warblers are an endangered species of bird that nest only in central Texas. They build their nests using bark from ash juniper trees and feed on spiders and insects. Brown-headed cowbirds sometimes lay eggs in warblers' nests, killing the warblers eggs. Blue jays are known predators of the golden-cheeked warblers' offspring. The survival of golden-cheeked warblers would be most threatened by an increase in the —
Answer:
C. clearing of ash juniper trees for farmland
Explanation:
Golden-cheeked warblers will be in more danger if "clearing of ash juniper trees for farmland" will increase because juniper trees provide barks to build the nest for Golden-cheeked warblers, if Golden-cheeked warblers will not get enough barks to build the nest, they will not able to reproduce and their population will decrease further.
Hence, the correct answer is "C".

Answer:
A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next

Use hydrogen bonding to explain how the unique properties of water you observed emerge.
Due to the existence of hydrogen bonding between the hydrogen atom and an oxygen atom of a water molecule, it shows the following unique properties.
It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.How the charges are distributed in a water molecule?The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.
This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.
Therefore, it is well described above.

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.

The eggs of a cone bearing plant:
receive sperm through the development of tubes
are held on the sticky fluid of the female cone
receive pollen from the wind
Answer:
Receive pollen from the wind.
Explanation:
The sperm of the male cone floats through the air and lands on the scale of the female cone. Sperm cells move through the pollen tube of the female cone and one of them fertilized an egg cell which eventually turns into a seed.
Answer:
The eggs of a cone bearing plant receive sperm through the development of tubes.
Explanation:
Cone-bearing plants have two types of cones: female cones and male cones. Reproduction begins when one of the pollen grains from inside a pollen sac on the male cone floats through the air to the scale of a female cone. A pollen tube then grows from the pollen grain toward the female ovule. Sperm cells move through the pollen tube and one of them fertilizes an egg cell, which then develops into a seed. The winged seed floats to the ground and begins to germinate. As the top of the seedling reaches for light, the hypocotyl straightens and the cotyledons spread out.

The chemical reaction equation of photosyntesis is shown here:
6CO2 + 6H2O → C6H12O6
What information is not given in this equation.
A)It does not show if the reaction is reversible or not reversible.
B)It does not show the reactants needed for the reaction.
C)It does not show that photosynthesis consists of many separate steps.
D)It does not show the number of molecules required to produce glucose.
Answer:
C
Explanation:
C appears to be the best answer but I think a better answer would be that it didn't include another product which is oxygen. So unless it is late and my brain is not function, I would say that should be the answer. But otherwise, since it is not there, C is the best one I think.
The chemical reaction equation of photosynthesis is shown here:
6CO2 + 6H2O → C6H12O6, C)It does not show that photosynthesis consists of many separate steps. Thus option "C" is correct.
What is photosynthesis?
The chemical reaction of photosynthesis is given as follows;
6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)
Therefore, six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight to produce one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)
The 6O₂ is the gaseous oxygen produced as a byproduct of photosynthesis

Explain the importance
of decomposers to the overall
biogeochemical cycle.
Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
Decomposers are essential for the biogeochemical cycle as they facilitate the recycling of nutrients, provide energy for other organisms, and help maintain the health and balance of ecosystems by Breaking down organic matter, Recycling nutrients, Energy flow and Detoxification.
Without decomposers, organic matter would accumulate, nutrients would become locked up, and energy flow within ecosystems would be disrupted.
Decomposers play a crucial role in the overall biogeochemical cycle. Here's why they are important:
Breaking down organic matter: Decomposers, such as bacteria and fungi, break down dead plants, animals, and other organic materials into simpler compounds. They do this through the process of decomposition, where they release enzymes that break down complex molecules into smaller, more manageable forms.
Recycling nutrients: By decomposing organic matter, decomposers release essential nutrients back into the ecosystem. These nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are then made available for uptake by plants and other organisms. This recycling of nutrients is vital for maintaining the balance and productivity of ecosystems.
Energy flow: Decomposers also play a crucial role in energy flow within ecosystems. When they break down organic matter, they release energy in the form of heat. This energy can then be used by other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers (carnivores), to carry out their life processes.
Detoxification: Decomposers are capable of breaking down and detoxifying harmful substances and pollutants in the environment. For example, certain bacteria can break down pesticides and other chemical pollutants, helping to reduce their negative impact on the ecosystem.
