1. How does the equations help explain the role of
producers in the ecosystem?
1. Producers create energy for other organisms to consume.
2. Producers convert sunlight into usable energy and Nitrogen.
3. Producers convert carbon dioxide and water into sugar.
4. Producers create Carbon dioxide for other organisms.
2. Aerobic Cellular Respiration is important to organisms because
1. It allows plants to produce sugar for food.
2. It releases the oxygen needed by plants for photosynthesis.
3. It converts sugars to usable energy that all organisms need.
4. It helps animals digest the sugars when they eat plants.
Answer:
1. Producers create energy for other organisms to consume.
2. It converts sugars to usable energy that all organisms need
Explanation:
All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.
2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.

Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”
Hypothesis: If the type of food available changes, then…
…because…
Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.
Explanation:
With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
What are different types of bird beaks?There are many types of beaks in birds, some of these can be:
Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.

What do you mean by biome?A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate.
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

support soft tissues inside bones
prevent friction between bones
connect bones to bones
attach muscles to bones
Answer: C
Explanation:
Ligaments are strips of tough tissues that serves as connective tissue for two or more bones and cartilages. These also holds the joints together.
Ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.
What is the significance of the ligament?Ligaments are significant for many different factors, such as that they have an important role in physical activities such as sports and maintain optimal performance and injury prevention as they have a rich blood supply. They have an important role in preventing injuries to joints and bones as they protect bones and cartilage from excessive stress and connect bones to bones.

In the United States, the moon’s pull is strongest during which season?
1. spring
2. summer
3. fall
4. winter
Explanation:
Gravitational pull is affected by mass and distance. Since the moon’s mass does not change, the moon’s distance between Earth and the moon is the main consideration for the strength of lunar gravity. The moon’s pull on Earth waxes and wanes as the moon follows its elliptical orbit around the Earth, the distance between the two celestial objects increases and decreases. When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.
On Earth, the moon’s gravity primarily is manifested as high and low tides, as the water bulges toward the moon. The effects of lunar gravity are felt the most at the constantly changing spot on Earth that is directly beneath the moon, called the sub-lunar point. At most times of the year, the moon has a greater pull on Earth than the sun does, but this changes during the times of year when the Earth’s orbit brings it closer to the sun. At these times, the sun’s gravitational pull causes spring tides, and when these coincide with the moon’s orbital perigee around the Earth, they are called perigean spring tides.
Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth. Over a very long time, the moon’s rotations created fiction with the Earth’s tugging back, until the moon’s orbit and rotational locked with Earth. This is called "tidal locking," and it explains why the same side of the moon always faces the Earth.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.

Which statement best describes Mendelian or complete dominance?
When both the dominant and recessive allele shows.
When the dominant and recessive alleles mix to form a third phenotype.
When the dominant trait or allele completely masks the recessive allele.
Answer:
When the dominant trait or allele completely masks the recessive allele
Explanation:
Mendelian or complete dominance is a relationship of genes in which one allele of a gene pair that codes for a trait expresses itself over the other allele of the gene pair. The allele of the gene pair that expresses itself over the other is the dominant trait or allele, which completely mask the expression of the other allele called the recessive allele or trait.
In the pea plant experiment conducted by Mendel, complete dominance can be seen. For example, for seed color of pea plant, allele for yellow seed color was dominant over allele for green seed color.
