Answer:
1. Having two similar gametes in which no differentiation can be distinguished, or reproducing by the union of such gametes.
e.g. in Spirogyra and Ulothrix
2. Anisogamy refers to a type of sexual reproduction in which two dissimilar gametes unite or fuse. The gametes may differ in size or form.
Example : human beings, the male gamete sperm is smaller and motile while the female gamete egg is non motile and larger.
3. having or involving a small motile male gamete and a large immotile female gamete.
E.g. Volvox, Fucus
Is a carrier of the disorder
The second type of body fluid, the extracellular fluid, have two types: the interstitial fluid and the intravascular fluid. The interstitial fluid serves as a messenger for transferring materials to and from cells. While the intravascular fluid is responsible for being within the circulatory systems of the body, being am addition of 4% of the body's weight.
Answer and Explanation:
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
- During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
- During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
- G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Tree > bird > red fox > bear
tree is the producer. bird is the 1 consumer. red fox is secondary consumer. bear 3rd consumer.
about 8% of energy is being transferred
