You are a biologist looking at samples of pond water. Using a microscope to investigate your samples, you identify a cell with a nucleus. Briefly explain how you know immediately that this is not a prokaryote. Additionally, without further investigation, would you be able to determine if it was a plant or an animal cell?
Answer:
You know it's not a prokaryote, because prokaryotes do not have a nucleus. You would not be able to determine if it was a plant or animal cell without further investigation because both have a nucleus.
Plant cells do have organelles that animals cells don't such as chloroplasts and cell walls, but you would have to investigate further.
The cell is eukaryotic one as it does not possesses a nucleus. For determining that the cell is of plants or of animals, the best way is to look at the criteria like cell wall, vacuoles, etc., which are present only in plant cells.
What is eukaryotic cell?Eukaryotes are organisms with nuclei in their cells. Eukaryotes include all animals, plants, fungi, and many unicellular organisms.
They are members of the Eukaryota group of organisms, which is one of the three domains of life. The other two domains are Bacteria and Archaea.
Plant cells have both a cell wall and a cell membrane. The cell wall surrounds the cell membrane in plants.
This is what gives plant cells their distinctive rectangular shape. Animal cells have only a cell membrane and no cell wall.
A cell wall, chloroplast, plasmodesmata, plastids, and various organelles are all found in plants.
Animal cells do not have cell walls, but they do have organelles such as tight junctions and cilia. The meristematic system, which is located at the tips of roots and stems, is responsible for plant growth.
Thus, this way, one can identify with further investigations that if it was a plant or an animal cell.

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.
Explanation:
both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.
Answer:
The correct answer is both dominant alleles are fully expressed in offspring. In the incomplete dominance inheritance, one allele isn't completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a brand new phenotype. for instance AB blood type in humans. In the given question Y is that the intersection of co-dominance set and incomplete dominance set. Thus, the realm Y may have one dominant allele from co-dominance and one allele which isn't completely dominant from incomplete dominance. Therefore, the label to marked area Y is also - both dominant alleles are fully expressed in offspring.

Answer:
C. Out of the leaf by diffusion.
Explanation:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane.
Examples of Osmosis: Examples include red blood cells swelling up when exposed to freshwater and plant root hairs taking up water. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Examples of Diffusion: Examples of diffusion include the scent of perfume filling a whole room and the movement of small molecules across a cell membrane. One of the simplest demonstrations of diffusion is adding a drop of food coloring to water. Although other transport processes do occur, diffusion is the key player.
Based on the above information, your answer is most likely
C. Out of the leaf by diffusion.

what Mendal law states that two hereditary factors separate when gametes are formed
Mendel's law of segregation states that the two hereditary factors separate when gametes are formed. When fertilization occurs, the offspring receive one hereditary factor from each gamete, so the resulting offspring have two factors. The law of segregation predates our understanding or meiosis.
Hope it helps...Answer:
Mendel's law of independent assortment states that the alleles of two or more different genes get sorted into gametes independently of one another. The allele a gamete receives for one gene does not influence the allele received for another gene.
Explanation:
Mendel’s law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes: every possible combination of alleles for every gene is equally likely to occur. The independent assortment of genes can be illustrated by the dihybrid cross: a cross between two true-breeding parents that express different traits for two characteristics.

All of the above Please select the best answer from the choices provided A B C D.
All of the options are applicable to organic farming.
Organic farmingOrganic farming is a form of farming that relies on natural processes for producing crops and livestock.
Thus, organic farmers avoid using synthetic products such as pesticides and agrochemicals on their farms. This makes them rely on the natural state of soils for crop production.
The natural health of the soil, however, depends on the interaction between organic matters and soil microbes to produce nutrients for the soil.

Why does our heart need two parts that are completely separate from one another?
Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

a-Have reproductive cells with flagella
b-Contain cell walls
c-Release chemicals to break down food
d-Lack hyphae
Answer:
D
Explanation:
Chytrids lack hyphae.
Answer:
d-Lack hyphae
Explanation:
It refers to the difference between them and also the characteristics which chytrid has.
They both have cell wall.They both are reproductive cells with flagella.fungi release chemicals to break down food but chytrids do not.fungi has general hyphae whereas chytrids does not. So chytrids lack hyphae and matches the characteristics.Why is having genetic information packaged into chromosomes beneficial?.
