Answer:
4. The offspring are the result of sexual reproduction
Explanation:
The amount of hyaline cartilage in the embryonic skeleton is much higher than in a child. This is because the embryonic skeleton will still go calcification as the embryo ages to fetus and eventually to being a child to adulthood.
Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.
Answer: Chloroplast, endoplasmic reticulum,lysosomes, nucleus, vacuoles.
Explanation:
The cytoplasm can be defined as the fluid that is found inside the cell. This liquid contains various types of salts and minerals dissolved in it.
All the organelles inside the cell is found in the cytoplasm. The organelles like nucleus, chloroplast, vacuoles, lysosomes and other organelles are found in the cytoplasm.
The cytoplasm provides stability, flexibility to the cell. Being the liquid part of the cell it prevents the cell from drying.
The appropriate title of the scatter plot is solubility curve of sugar
The independent variable is temperature
The dependent variable is mass of sugar in grams that can dissolve in 100 mL of water
The solubility curve is a graph of the amount of solute dissolved in a given volume of solvent against temperature.
The solubility of the solute is plotted on the vertical axis while the temperature is plotted on the horizontal axis.
The independent variable is the temperature while the dependent variable is mass of sugar in grams that can dissolve in 100 mL of water.
