<u>The presence of </u><u>embryos </u><u>is the features would definitively identify this organism as a </u><u>land plant.</u>

How could you determine if a plant is heterosporous?

Male and female reproductive structures are located on separate plants.

What is embryo of plant?

Definition. (botany) A young, developing plant, such as the rudimentary plant inside the seed of higher plants or that inside the archegonium of mosses and ferns.

What is embryo and its function?

  • An embryo is an early stage of a multicellular organism's development.
  • Embryonic development is the phase of life cycle that starts right after the male sperm cell fertilizes the female egg cell in sexually reproducing animals.

What is Heterospory ?

Heterospory characterizes plants that produce spores of different sizes: megaspores and microspores which give rise to separate female and male gametophytes, respectively.

<u>The complete question is -</u>

On a field trip, a student in a marine biology class collects an organism that has differentiated organs, cell walls of cellulose, and chloroplasts with chlorophyll a. Based on this description, the organism could be a brown alga, a red alga, a green alga, a charophyte recently washed into the ocean from a freshwater or brackish water source, or a land plant washed into the ocean. The presence of which of the following features would definitively identify this organism as a land plant?

eduard

Answer: Anconeus muscle

Explanation:

The anconeus is a small muscle found at the elbow. It is Attached to the humerus and ulna (it originates on the lateral epicondyle of the humerus and inserts on the olecranon process and superior portion of the ulna). Anconeus muscle allows the forearm to extend and it also provides support for the dorsal joint capsule and the ulna as well.

The radial nerve permits the anconeus muscle to carry all of those functions.

barxatty [35]
Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled. 

The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True

Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

Answer:

Exergonic reaction

Explanation:

  • A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.
  • An exergonic reaction owing to the negative free energy change is a spontaneous reaction.
  • The energy that is released in the exergonic reaction is usually observed  in the form of heat and light.
  • The energy is released due to the breaking of the chemical bonds.
  • Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.
