Answer:
-The top bird with a beak adapted for insect eating would not succeed on a Galapagos Island with little insects but plentiful seeds.
-The middle bird with a woodpecker beak adapted for seed eating most likely could dig deeper for larger, harder covered insects more successfully than the top bird with the insect eating beak.
-The bottom right bird with a beak adapted for seed eating would succeed on a Galapagos Island with plentiful vegetation and few insects.
Explanation:
The theory of natural selection explains that organisms undergo changes in their physical and genetic features that make it possible for them to adjust to their environments. There are different types of birds having different shapes of beaks adapted for life in several environments.
There are insectivorous birds whose beaks are adapted for eating insects, granivorous birds with short, conical beaks for cracking seeds, frugivorous birds adapted for eating fruits, nectivorous for sucking nectars, among others. The adaptations are unique to the birds and determine their survival and feeding habits in several environments.
Which of the following is a direct economic advantage associated with aquaculture?
A
Aquaculture breeds genetically modified fish to increase the
amount of biodiversity in the population.
B
Aquaculture reduces the number of fishing operations in an area.
С
Aquaculture produces large amounts of seafood for human
purchase and consumption year-round.
D
Aquaculture requires large bodies of water for its operations.
Answer:
c Aquaculture produces large amounts of seafood for human
purchase and consumption year-round.
Explanation:
Most seafood produced via aquaculture is destined for human consumption, which has added to the sector’s momentum. The ability to dependably harvest many different species of finfish, shellfish and aquatic plants has also facilitated gains for the world’s aquaculture industry.
write a note on profundal zone
Answer:
Profundal zone is the deep water zone of any lentic water body i.e. lake or a pond where the light can no longer penetrate because it is located below the range of effective penetration of light mostly below the thermocline. The lack of light and oxygen determines the type of biological community living there

Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which
occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the
following is an exampleof phenotypic plasticity?
Well-maintained hedges can be shaped into artistic displays.
O A person who experienced malnutrition as a child is short in stature as an adult.
O Bears living in the arctic developed white fur and cold tolerance over many generations.
Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.
Answer:
O A person who experienced malnutrition as a child is short in stature as an adult.
Explanation:
Height is a quantitative trait, i.e., a phenotypic trait that depends on the combined action of many genes and the environment. Moreover, phenotypic plasticity can be defined as the ability of one genotype to produce different phenotypes in different environments. In consequence, quantitative traits are influenced by environmental factors and exhibit phenotypic plasticity. Quantitative traits are characterized to have a large variety of phenotypes and follow a normal distribution (a bell-shaped curve) when they are drawn.

Plants use chlorophyll during photosynthesis to absorb ------------
choices
A. sugar
B. light
C. water
Answer:
B. Light
Explanation:
In addition to giving plants their green color, chlorophyll is vital for photosynthesis as it helps to channel the energy of sunlight into chemical energy. With photosynthesis, chlorophyll absorbs energy and then transforms water and carbon dioxide into oxygen and carbohydrates.
Answer:
B. light
Explanation:
chlorophyll job is to absorb light from the sun
Many people who own pet fish put a pondweed called Elodea canadensis in their
fish tanks. This species of pondweed produces an extremely high amount of oxygen.
If many fish were placed in a tank without this species of pondweed or a filter, what
would likely happen?
Answer:
In the scenario given above, Elodea Canadensis which produces extremely high amount of oxygen is used in raising fishes placed in a tank. This oxygen is needed for easier living in the tank. In a situation whereby the Elondea Canadensis is not present in the tank, the fish would struggle to leave comfortably in the tank. with time, the water will become clouded with carbon-dioxide. This would lead to the fish dying due to lack of oxygen.

Learning Task 6: Complete the chart. Copy this in
your answer sheet.
Answer:
Canopy
Sub-canopy
Understory
Floor of the forest
Explanation:
Canopy refers to the aboveground portion of a plant or crop such as stem, leaves, branches and flowers etc.
Sub-canopy refers to those plants which are present below the trees due to their lower size such as small trees and large shrubs etc.
Understory is the vegetation that is present on underlying layer in a forest such as herbs etc.
Floor of the forest is mainly consists of shed vegetative parts of shrubs and trees, such as leaves, branches, bark, and stems etc. These parts exists in various stages of decomposition present above the soil.
List the layers of Earth’s atmosphere in order of increasing altitude.
A.
troposphere, stratosphere, mesosphere, thermosphere, exosphere
B.
exosphere, thermosphere, mesosphere, stratosphere, troposphere
C.
troposphere, stratosphere, mesosphere, exosphere, thermosphere
D.
stratosphere, mesosphere, thermosphere, exosphere, troposphere
Answer:
A
Explanation:
These are the correct layers in order of increasing altitude.
Answer:
Ionosphere
Explanation:
The temperature in the ionosphere increases as altitude increases. In the ionosphere, a layer known as the thermosphere starts. The name thermosphere comes from the temperature increasing as altitude increases.
describe the effects that fire in the temperate grasslands biome has on grasses and on trees
Answer:
When fire is suppressed, the vegetation eventually converts to scrub and dense forests. Often, the restoration or management of temperate grasslands requires the use of controlled burns to suppress the growth of trees and maintain the grasses. Burning causes new grass to grow, which brings back the grazing animals.

What is the is the difference between the littoral and limnetic zone?
Answer:
The topmost zone near the shore of a lake or pond is the littoral zone. The near-surface open water surrounded by the littoral zone is the limnetic zone. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton.

What causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.

3. How does your body ensure that the new cells are the same?
Answer:
When cells split and increase they do this very important thing in order tonmake the new cells exactly the same as the previous before them. Each cell makes more of all it's genes. Then each one.splits into two with one group of genes in each one of the new cells. During the process they make sure that all are copied correctly.
What do you think the term gene expression means? How do you think the term relates to the total number of genes a human inherits from his or her parents?
Answer: Gene expression is how genes are expressed in an organism. This relates to the total number of genes from each parent because the number of genes from each parent determines how your genes are expressed physically.
