Answer:
Fern
Explanation:
The plant discovered by the botanist is most likely a fern.
Ferns are referred to as seedless vascular plants. They do not produce seeds and they possess vascular tissues in the names of xylem and phloem. The xylem conducts water/mineral salts from the roots to the body of the plant while the phloem distributes manufactured foods from their sources to other parts of the plant.
Ferns also have independent gametophyte and sporophyte stages. The sporophyte produces haploid spores through meiosis which then germinates to the gametophyte. The gametophyte produces male and female gametes - antheridium and archegonium. The antheridium is motile and swims to meet the immotile archegonium during fertilization to produce the zygote which then divides mitotically to give the sporophyte.

Which of these organisms would most likely be found at the top of an energy pyramid?
A. clams - a primary consumer
B. sardines - a primary consumer
C. sharks - a secondary consumer
D. kelp - a primary producer
Answer:
sharks
Explanation:
Because they are the ones to get the last bit of energy. Secondary consumers are the group in the food chain that eats primary consumers. This means that secondary consumers can either be omnivores or carnivores. These terms refer to whether or not they eat just meat or a varied diet. Secondary consumers don't need to have a specific diet.
The energy pyramid is a representation of the producers and consumers along with the flow of energy. The sharks will be at the top of the energy pyramid. Thus, option C is correct.
What is an energy pyramid?An energy pyramid is a graphical representation of the biomass of the producers and the consumers of the ecosystem. It consists of the trophic levels that have designated producers, primary consumers, and secondary consumers.
A producer is at the bottom of any energy pyramid as they produce the foods for the primary consumers that are most likely herbivores. The secondary or the tertiary consumers are at the top.
Therefore, option C. sharks being secondary consumers are at the top of the pyramid.

Identify the phases in the life cycle of small and big stars. supernova: In this stage, the star collapses and produces elements heavier than iron. planetary nebula: In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core. neutron star: In this stage, the star has reduced to an extremely dense core. white dwarf: In this stage, the star has reduced to a dense core.
Explanation:
Some Astronomers believe the life cycle of small stars begins in this order:
Planetary nebula phase: this phase is the result of the previous red giant phase (when the star turns red in color). However, at this stage, the star keeps expanding, glowing, and getting hotter as it strives to complete its life--cycle.White dwarf phase: As the name implies, the star now has a reduced size and a dense core than during the Nebula phase, while still glowing with surface temperatures of over 100,000°C.Neutron star: This stage occurs next after the White dwarf phase which may result in the final death of the star. Here the star is reduced to an extremely dense core.While the life cycle of big stars begins in the order:
Supernova phase: At this phase, the star collapses and produces other heavier elements.Neutron star phase or may formBlack Holes.Unstable individual atoms are made stable as a result of

PLS HELP ME I’ll GIVE YOU 15 POINTS OR BRAINIEST
Answer:
1.0 mole per dm3 sodium chloride solution
Explanation:
The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.
Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.
Why does humus tend to increase with the clay content of soil?
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
B.
As the clay content increases, the amount of plant lignin in the soil increases.
C.
As the clay content increases, the permeability decreases, which increases the rate of decomposition.
D.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which increases the rate of decomposition.
Answer:
A.
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
Explanation:
This is true because, humus which is the dark rich matter made up of organic matter would be able to be adsorb into the clay content of the soil due to the size of the particles component. The surface area in the soil is a strong factor when compared with other soil type with smaller surface area.

The resting membrane potential of a neuron is generated by Group of answer choices the selectivity of the membrane to pass positive charges only. the greater mobility of small ions. diffusion of ions as a result of their concentration gradients. All of them repulsion of positive and negative charges.
Answer: diffusion of ions as a result of their concentration gradients.
Explanation:
Resting membrane potential can be defined as the basic charge of the cell. It is defined by the concentration difference between the ions due to the action of the ion pumps. The differential permeability of the membrane is because of the charge on the ions and leads to the creation of the ion channels. The negative charged ions accumulate on the inner side of the cell.
If you were to test a small
sample of soda lime with
universal indicator would it
register a pH above or
below 7? Explain your answer
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.
