A train is to cars as a molecule of DNA is to -------

The correct option is

The number of organisms being born equals the number of organisms dying.

Explanation:

A population at carrying capacity is neither increasing nor decreasing. When the numbers of individuals in a population of animals, plants or humans exceed their carrying capacity, deaths outnumber births. As the population drops blow carrying capacity, the birth rate grows until births outnumber deaths. Therefore, the number of organisms being born must be equal to the number of organisms dying.

The right answer is C

The carrying capacity (or carrying capacity, or limiting capacity) in ecology is the maximum size of the population of an organism that a given environment can support, ie the capacity of this environment to:

- provide the necessary resources to ensure the sustainability of this species - repair the attacks (pollution, disruption of natural ecological regulations) inflicted by this species on its environment.

At this size a balance will be reached between the number of organisms born and the number of dead organisms.

The characteristics that are common in angiosperms are flowering plants that have seeds covered under fruits.

What are the characteristics common in angiosperms?

• Angiosperms are flowering plants that have seeds covered under fruits.
• These are eukaryotic, multicellular, and non-motile living organisms.
• These are land plants that have diverse habitats.
• Their plant body is divided into roots, stem, and leaves.
• They have a well-defined vascular system consisting of xylem and phloem vessels.
• Secondary growth is seen in angiosperms.
• These can be annual or perennial, evergreen or deciduous, and woody to herbaceous. These consist of herbs, shrubs, and trees.
• Angiosperms vary in size, from duckweed being the smallest one to Eucalyptus being the tallest one.
• The sex organs are found inside the flower.
• The stamen consists of a filament and anthers, while the carpel comprises stigma, style, and ovary.
• Angiosperms have unique double fertilization.
• The life cycle of angiosperms shows an alternation of generation.
• The sporophyte phase is dominant, while the gametophyte phase is reduced.

#SPJ2

Answer: Flowers (and to be more specific), this includes a fruit which may or may not be your regular "fruit".

Explanation: All angiosperms are flowering plants which include a flower and a flower that produces fruit.

Answer: Endangered species are species whose populations are dwindling in numbers and are in danger of becoming extinct. Extinct species are ones who have no documented individuals left and are therefore believed to no longer exist.

Answer:

It is Individuals

Explanation:

Kilocalories is for energy pyramid g C/m^2 is biomass m/s^2 is probably related to speed, so that leaves us with Individuals.

Answer:

It is a graphical representation of biomass (total amount of living or organic matter in an ecosystem) present in unit area in different trophic levels. Typical units are grams per square meter, or calories per square meter. The pyramid of biomass may be "inverted".

Explanation:

Answer:

B. Convection currents in the mantel cause the movement of crustal plates.

Explanation:

This process is what causes plate tectonics, and doesoccurs in nature. All other options were false.
