Atria is a large part of the heart so too big for cells; arteries & veins lead away or to the heart.
Capillaries are the smallest vascular structures that allow materials to be exchanged easily between cells.
The answer here is a CUTICLE.
Cuticle is a multifunctional exoskeleton. It serves nematodes a variety of benefits. It aids in their locomotion via linkages to the body muscles as well as serve as barrier from the environment. Uniquely, the flexible yet resilient, extracellular matrix is synthesized five times and contains collagen, insoluble proteins, glycoproteins and lipids.
Answer:D) Decomposers break down the remains of producers and consumers
Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.
The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.
This tell us that the ultimate dead part of producers and consumers are used up in this process.
Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.
Note: The biogeochemical cycle is a pathway of movement for chemical elements.
The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem
Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.
All living and non living elements of nature play vital roles in the great biogeochemical cycle.
Answer:
The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.
Explanation:
As you can see in the attached table
1. For the size of the flagella we gave that:
- 241 organisms have long flagella
- 79 organisms have short flagella,
As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.
2. For the number of vacuole we have:
- 247 organisms have one vacuole
- 73 organisms have two vacuole
As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.
Then
Dominant phenotypes = Long flagella and one vacuole
Recessive phenotypes = Short flagella and two vacuoles
The answer is A. EUKARYOTIC PLANT
