Your assignment is to write a first-person story entitled “Life as a Blade of Grass." In your story, you will write an account of your journey through the digestive tract of a farm animal, from the mouth through the colon and out of the body. Your story should start with something like, "I was just standing there minding my own business when a hungry cow approached..."
Answer:One day a cow named Spots woke up. She noticed she was in a desert. She looked around. She saw there was no grass for her to eat, so she went back to sleep. The next day she was hungry, very hungry. All she saw was a cactus and dirt on the ground. The cactus had little spikes. There was only lizards and flies around. She had no food, no water and no friends. Spots was very sad. She got up and started to walk. She walked all day and the next day too. Finally she came to a farm. She wondered where the animals were. All she saw was a husband and wife. They only had cereal with no milk. It was dry. They wished they had milk. Spots asked if she could help by giving them some milk. They said yes and never went hungry again, neither did Spots the cow.

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.

Will people pick up a dollar bill that is dropped on the floor in the airport during a pandemic?
Answer:
No.
Explanation:
The factors of an experiment is considered as independent because it does not change or not dependent on other while on the other hand, the data is the dependent variable due to its dependency on the treatments. No, people will not pick up a dollar bill which is dropped on the floor in the airport during a pandemic because they can't put their life in danger for a dollar. They knew that life is more important than money.
If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis
Answer:
Leaves have an increased surface area in order to increase light-harvesting and they are thin in order to increase the diffusion rate
Explanation:
Leaves have several adaptations to increase the photosynthesis rate. In the first place, leaves have a large surface area to increase light-harvesting and thus also increase photosynthetic energy conversion. Moreover, leaves are sufficiently thin to increase the gas exchange surface area, i.e., the entry of carbon dioxide (CO2) and the exit of oxygen from photosynthesis, which move by diffusion through stomata.

A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall. After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure. Complete the following statements about the two bat species.

Complete question:
A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall. After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure. Complete the following statements about the two bat species.
Roosting areas in buildings of any height are the _________ of species 1.Roosting areas in buildings of any height are the _________________ of both bat species.____________ between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), __________ of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the __________ of species 1 when species 2 is present.a. fundamental niche
b. realized niche
c. character displacement
d. intraspecific competition
e. interspecific competition
f. (-\-)
g. resource partitioning
h. competitive exclusion
Answer:
Roosting areas in buildings of any height are the fundamental niche of species 1.Roosting areas in buildings of any height are the fundamental niche of both bat species.Interspecific competition between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), competitive exclusion of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the realized niche of species 1 when species 2 is present.Explanation:
The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The fundamental niche refers only to environmental conditions in which a species can live and survive in the absence of any interaction with other species. The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the interaction with other species.Interspecific competition refers to the interaction between two or more species that use the same fundamental niche. These species compete for the same resources like food, shelter, or water, among many others. Eventually one of the species dominates and the other is displaced. Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor. Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely -, migrate or get extinguished.A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.
In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.
