Answer 1

Answer:

true

Explanation:

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

Answers

Answer:

Continental shelf

Explanation:

I checked in lesson also took the exam.

continental shelf exposed during glacial periods but covered by ocean water during non-glacial periods.

What is a continental shelf?

The undersea boundary of a continent is known as a continental shelf. The seven major divisions of land on Earth are called continents. From a continent's shoreline to a point known as the shelf break, a continental shelf runs.

Due to its relative accessibility, the continental shelf is the area of the ocean floor that is most understood. The continental shelf is where the majority of commercial sea resource extraction occurs, including the extraction of hydrocarbons, non-metallic ore, and metallic ore.

Thus, the continental shelf is exposed during glacial periods but covered by ocean water during non-glacial periods.

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops

Answers

Answer:

c The movement of energy between organisms

Explanation:

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.

Furthermore, a list of the types of organisms in an eco pyramid are;

I. Producers: these are autotrophs or self-feeders such as plants.

II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.

III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.

IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.

Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.

Explanation:

In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,

Grass-------> Zebra ---------> lion

(Primary (Primary ( secondary

producer). consumer) consumer)

this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.

Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

7. What biological process occurs after there has been a disturbance such as a flood, or a tornado-in an established ecosystem?

Answers

Answer: Ecological disturbance, an event or force, of nonbiological or biological origin, that brings about mortality to organisms and changes in their spatial patterning in the ecosystems they inhabit. Disturbance plays a significant role in shaping the structure of individual populations and the character of whole ecosystems.

Answers

Answer:

d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates.

Explanation:

In evolutionary biology, a synapomorphy is a shared, derived character/trait which is present in an ancestor and its descendants. Synapomorphies are useful markers to establish phylogenetic relationships between sets of taxa. Tunicates (subphylum Tunicata) are sessile marine invertebrates that are considered chordates (phylum Chordata) because the larval stage has characters/traits that are similar to other chordates. Larval tunicates have a nerve cord, a notochord, tail and gill slits (conserved in adults).

The graph below shows the population of mice living in a certain area over fifteen years Which numeral on the graph points to a time when the birth rate exceeded the death rate of the mice?

I

II

III

IV​​

Answers

Answer:

I

Explanation:

In section I, the graph has a positive slope.

Birth rate - death rate = positive, the birth rate is more than the death rate

Sections II and IV have a balanced population where the birth and death rate are the same

In section III the death rate exceeds the birth rate

The numeral I on the graph points to a time when the birth rate exceeded the death rate of the mice.

What is death rate?

The mortality rate, also known as the death rate, is a measure of the number of deaths in a given population per unit of time, scaled to the population's size.

The birth rate is the number of people born in a population in a given period of time. The number of people born per year per 1000 in the population is referred to as the human birth rate.

In section I, the graph has a positive slope. Birth rate and death rate difference is positive here, it means the birth rate is more than the death rate.

Sections II and IV have a balanced population with the same birth and death rates. Section III has a higher death rate than a higher birth rate.

Thus, the answer is numeral I.
