Sort the descriptions based on whether they are related to asexual reproduction or sexual reproduction
miss Akunina [59]

Answer:

Sexual Reproduction:

  1. Creates genetically unique offspring.
  2. Organism needs time to  reach adulthood and to reproduce.
  3. Requires the contribution of two parents.

Asexual Reproduction:

  1. Creates genetically identical offspring.
  2. Organism doesn't have to waste energy to find a mate.
  3. Requires the contribution of a single parent.

Explanation:

Sexual Reproduction:

  • Sexual reproduction involves the fusion of a male and female gamete. A gamete is a haploid cell that contains half of the chromosomes as in the parent cell. This process is called fertilization and it results in the formation of a zygote, a diploid cell that develops into an embryo and ultimately an individual.
  • Sexual reproduction involves two parents, each of which contributes one set of chromosomes (23) to the offspring.

Asexual Reproduction:

  • Asexual reproduction produces an exact copy of one single parent. Offspring produced through asexual reproduction do not possess genetic variation.
  • Asexual reproduction occurs through four processes:
  1. Binary fission
  2. Fragmentation
  3. Budding
  4. Parthenogenesis

Look at the image below? When do you think the fault (break) in the rock happened? After which layer was deposited?
ycow [4]

Layer C

Explanation:

The fault break occurred after layer C in the rock sequence.

Layer C is an igneous intrusion through the rock.

To interpret this sequence, we need to apply the law of superposition of strata and cross-cutting .

The law of superposition of strata states that "in an undeformed sequence of strata, the oldest is at the base and the youngest is on top".

Law of cross-cutting states that "intrusions and faults are younger than the rocks they cut through".

  • The intrusion is the last even before the fault because it cuts through layers A, B D and E.
  • After the intrusion then the faulting event happened.

How does the body of a 100m sprinter produce energy for this event?
mafiozo [28]
Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!

A geologist is studying a rock core sample of a hillside. Which would be the BEST evidence that this hillside was once covered b
sergeinik [125]
Answer: Aquatic fossils would be found near the bottom of the core sampleRock cores provide valuable sources of information to geologists because it presents very accurate measurements of porosity of the rock. If a geologist obtained the rock core from a hillside and found aquatic fossils near the bottom of the core sample, he can conclude that this hillside was once covered by a body of water.
