Answer: So this is like a food chain chart. The animals at the top are one top of the food chain and do not get eaten by anything; they dont have any predators. This chart goes from bottom up. So the plants have arrows pointing to animals. Those animals that the plants are pointing to are the animals that eat that plant. And then those animals point to another animal higher on the chain and those animals that are higher eat the animals that are lower than them and have the arrow pointing at them. So the snake is pointing to the owl because the owl eats the snake. The frog is pointing to the snake because the snake eats the frog. And the list on the side of the chart is just a list of different kinds of animals. I dont remember what each of them are so you are going to have to find out what element is missing.

1 How do animals receive their necessary nitrogen?
2. Why can't plants use nitrogen gas directly?
3. Explain why bacteria are essential parts of the nitrogen cycle.
Answers
2.) nitrogen is “unavailable” to plants, because the gaseous form cannot be used directly by plants without undergoing a transformation. To be used by plants, the N2 must be transformed through a process called nitrogen fixation.
3.) Bacteria help the nitrogen change between states so it can be used. When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
2. Even though nitrogen gas makes up most of Earth's atmosphere, plants cannot use this nitrogen gas to make organic compounds for themselves and other organisms
3. The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms. Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb

Answers
Answer:
Some of the functions of lipids are to provide long term energy, insulation and cushion organs.
Explanation:
Lipids are biomolecules —predominantly formed by carbon and hydrogen— of great importance to the body, since they are the main component of cell membranes and form part of the structure of necessary organic substances, such as hormones.
Within the functions of lipids are found:
Being a reserve energy source, which can be used in the long term. Body lipids serve as thermal insulators, especially when they are found under the skin. The lipids can cushion the internal organs that they cover, protecting them from trauma by body movement or external trauma.the other options are not correct because:
A. The nucleic acids are the ones that store the genetic information.

Answers
Answer: agree
Explanation:
The common argument which is based on shared assets and the behavior of each individuals.
When the land ownership becomes private a tragedy is avoided as each individual treats the land with care and caution, unlike when it’s a common( shared) where they all don’t care what happens to the land or it’s aftermath so far they all gain personally. So yes when it’s a private land then and then do they truly prevent any tragedy associated with common to happen.

Retina provides a sense of vision.
Select one:
a. False
b. True
Answers
Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses that are sent to various visual centres of the brain through the fibres of the optic nerve. Neural signals from the rods and cones undergo processing by other neurons, whose output takes the form of action potentials in retinal ganglion cells whose axons form the optic nerve.[1] Several important features of visual perception can be traced to the retinal encoding and processing of light.
In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue. It is the only part of the CNS that can be visualized non-invasively. Ever since you were little, you’ve been hearing lots of hearsay about your eyes and how to keep them healthy. Are carrots really good for your eyes, and will they help you see in the dark? Will reading fine print at night make your eyesight go bad? While many of these are based in fact, they aren’t entirely true. Let’s try to sort the fact from the fiction.
Damage Versus Fatigue
Many of these eye myths involve the threat of damage to your eyes. You may have heard that reading in dim. The retina is an essential part of the eye that enables vision. It's a thin layer of tissue that covers approximately 65 percent of the back of the eye, near the optic nerve. Its job is to receive light from the lens, convert it to neural signals and transmit them to the brain for visual recognition.

Credibility is essentially the believability of the study, and it is determined by both the trustworthiness and expertise of the researcher. Recently, concerns have arisen over Nalgene drinking bottles and the chemicals they may be releasing into the water. Two scientists publish their findings. One who works for a major Nalgene producing company, the other does not. Which scientist is more credible?
Answers
Answer:
The scientist who has no conflict of interest is, in principle, more reliable
Explanation:
All scientific publications must include a Declaration of Interest (also known as Disclosure Statement) by which authors state that there's no personal or financial interest that might be affecting the objectivity of their investigations, results and conclusions. If no conflict exists, the author should indicate that "there is no conflict of interest". In this case, the scientist who works for a Nalgene producing company should state that it is a potential conflict of interest.

12. Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley
team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but
hiked at high altitude, where there is much less oxygen. Which team probably had an easier time
hiking?
a
Both teams had an easy time hiking because their digestive systems broke down proteins
into amino acids for cells to release energy.
b
Neither team had an easy time hiking: the Valley team's cells needed more glucose from
broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from
air.
С
The Mountain team had an easier time hiking: their cells released energy from protein
reacting with glucose, which was broken down from starch in the digestive system.
d
The Valley team had an easier time hiking; their cells released energy from protein breaking
down in the digestive system, which then combined with oxygen in cells.
Answers
Answer: B. Neither team had an easy time hiking; the Valley team's cells needed more glucose from broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from air.
Explanation:
Before the hiking by the scientists, we are told that the Valley team ate a lunch of mostly protein while the Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen.
Based on the above, none of them had an easier time hiking. This is because since the cells of the Valley team who mostly ate protein, need glucose in order for a reaction to occur. For the Mountain team, even though they are a mixture of starch and protein, they went higher which reduced where there was less oxygen. This will have resulted in a hard time for them.
Therefore, neither had a easy time hiking. The correct option is B.

Chloroplasts contain chlorophyll a, chlorophyll b, and carotenoids. Why is this important in the process of photosynthesis? Support your answer with facts.
Answers
Answer:
Explanation:
Photosynthesis is the process by which green plants synthesize their food from carbon dioxide and water by using the green pigment chlorophyll generating oxygen as product.
Chlorophyll "a " absorbs light from the orange-red and violet-blue areas of the Electromagnetic spectrum. Also Chlorophyll a transfers energy to the reaction center and donates two excited electrons to the electron transport chain
Its main role is as a primary electron donor in the electron transport chain. So the energy from the sun will ultimately become chemical energy that can be used by the plant for cellular processes.
Chlorophyll "b" absorbs blue light. The main role is to expand the absorption spectrum of organisms.
Plant can absorb more energy from the high frequency blue light part of the spectrum. Its presence in cells helps plant convert a wider range of the energy from the sun into chemical energy.
Carotenoids are usually red, orange, or yellow pigments, and include the compound carotene. These compounds are composed of two small six-carbon rings that are connected by a "chain" of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments.
Answer:
The presence of chlorophyll a, chlorophyll b, and carotenoids in chloroplasts allow plants to absorb more energy from sunlight by absorbing multiple wavelengths. Chlorophyll a absorbs blue-violet light and red light. Chlorophyll b absorbs mostly blue light. Carotenoids absorb violet, blue, and blue-green light. The pigments together, therefore, are able to absorb a wider range of wavelengths.
