Answer:
number 3 is the central vacuole and its large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell
Explanation:
Answer:
3. Vacuole
Explanation:
Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).
It occupies 90% of the volume of the plant cell. Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.Some other points:-
Amoeba have contractile vacuole for osmoregulation and excretory purposes. Some protists develop food vacuoles by engulfing food particles.If you were building a swimming pool in your yard, what two metric units would be BEST suited for the measurements?

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.

Determine which of the following statements is true about energy in ecosystems.
A. Primary producers lose 20% of the energy they absorb as urine and feces.
B. Consumers pass on 20% of the energy they get from a lower trophic level.
C. Primary consumers lose 60% of the energy they absorb from producers as urine and feces.
D. 10% of the energy Primary consumers absorb is lost as heat.
The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.
What is an ecological pyramid?An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.
The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.
The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.
Therefore, option D. primary consumers absorb only 10% of energy.

Answer:
The answer is D: The blood pressure would increase.
Explanation:
The typing of human blood is determined by three alleles: A, B, and O. Alleles A and B are codominant to one another and O is recessive to both alleles, A and B.
AA/ AO – type A blood, AB – type AB blood, BB/ BO – type B blood, OO – type O blood.

Explanation:
Use the following information to calculate the correct frequencies: In a population of
Pennsylvanians, only 18% of individuals express the recessive trait of Syndactyly or webbed finger
(formulas: p+q=1 and p²+2pq+q2²=1)
a. What percentage of the population are not Webbed?
If we have the recessive genotypic frequency, we can calculate the phenotypic frequencies in a population in Hardy-Weinberg equilibrium. The percentage is 82%.
What si the Hardy-Weinberg equilibrium theory?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.
The allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies after one generation are
• p² ⇒ H0m0zyg0us dominant genotypic frequency,
• 2pq ⇒ Heter0zyg0us genotypic frequency,
• q² ⇒ H0m0zyg0us recessive genotypic frequency.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
Available data:
18% of individuals express the recessive trait of Syndactyly
Let us say that the dominant allele is A and the recessive allele is a.
The dominant allele A codes for normal finger.The recessive allele a codes for webbed finger.Assuming this gene expresses complete dominance,
H0m0zyg0us dominant and heter0zyg0us -AA and Aa- individuals have normal finger.Their frequency in the population is p² + 2pq.
h0m0zyg0us recessive -aa- individuals have webbed finger.Their frequency in the population is q².
Individuals that express Syndactyly have webbed finger and their genotype is h0m0zyg0us recessive, aa. Their frequency in the population is q².
q² = 18% = 0.18
We can get the frequency of individuals with normal fingers by clearing the following equation,
p² + 2pq + q² = 1
p² + 2pq + 0.18 = 1
p² + 2pq = 1 - 0.18
p² + 2pq = 0.82
The frequency of individuals with normal fingers is p² + 2pq = 0.82 = 82%.
The percentage of the population are not Webbed is 82%.
