Answer:
the Y chromosome is smaller than the X chromosome.
Explanation:
The male has an X and Y sex chromosome which is an exception to the general rule that homologous chromosomes are identical as the Y chromosome is smaller thus enabling it to swim faster than the X chromosome. The Y chromosome also has a longer lifespan compared to the X chromosome. The male genotypes is XY. Males are heterogametic as they produce two types of gametes, one carrying the X and the other carrying a Y chromosome.
Robert Hooke observed the cells through a combination of lenses.
After Robert Hooke, the development of microscopy take place. After the development of the microscopy, scientist were able to observe the features of the cell. In order to formulate a cell theory observation of most of the cells was necessary. So, it was necessary to observe different types of cells from different organism. So, the advancement of the microscopy and observation process required for the formulation of the cell theory was the reason for the delayed development of the cell theory.
B)
Both occur in only one direction.
The ability of a muscle to exert force is endurance.
Answer:
Ice is not an organic molecule.
Explanation:
Organic molecules are a specific type of molecule that contain at least one carbon atom that is attached to other atoms such as Hydrogen, oxygen.
In the given question lipid,carbohydrate and nucleic contain carbon atoms that are linked together with Hydrogen atoms, oxygen atom and nitrogen atom as a result they can be categorized as organic molecule.
on the other hand ice is the solid form of water(H2O) which itself is an inorganic molecule,from that point of view ice is not an organic molecule.
