Answer:
II. meiosis
III. fertilization
IV. gametes
Explanation:
Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.
Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.
Answer:
For men: 66 + (6.2 x weight) + (12.7 x height) – (6.76 x age)
For women: 655.1 + (4.35 x weight) + (4.7 x height) – (4.7 x age)
Explanation:
Answer:
these seemingly dissimilar organisms might have evolved from a distant
Explanation:
Evolution deals with history of organism survival on Earth.
The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.
Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.
The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.
Therefore, we conclude that "these seemingly dissimilar organisms might have evolved from a distant" is the right answer.
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
