The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.

Answer: 4.6 billion years.

Just clean the garage and ignore the wasps, they shouldn’t hurt you unless you do something to upset them.

1. Your unique genetic identity comes from three different events; crossing over, random alignment, and random fertilization. Ex
svetlana [45]

Answer:

Crossing over and random alignment are the events of meiosis-I that add new gene combinations to the gametes. Random fusion of male and female gametes is called random fertilization.

Explanation:

During the pachytene stage of meiosis-I, part of the chromatids of each of the homologous chromosomes of a bivalent is broken apart and exchanged. This exchange of the genetic material between the members of a bivalent is called crossing over. The recombinant chromatids formed by crossing over have new allele combinations that were otherwise not present in the parental chromatids.

During metaphase I, the homologous pairs are aligned at the cell's equator in a random manner. This means that either the paternal or maternal chromosome of a pair may face one or the other pole of the cell. The arrangement of chromosomes during metaphase-I determines whether the paternal or maternal chromosome of each pair would be distributed to one or the other pole of the cell. This random segregation creates new gene combinations in gametes.

All the gametes have equal chances of getting fused with a gamete from the opposite gender. This is called random fertilization and further adds variations.

Mrrafil [7]

Answer:

Explanation:

The production of ATPs for skeletal muscle contraction  depends on the conditions that the muscles are exposed to.

In presence of abundant oxygen, to the cells  Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each  of the 2 acetyl Co A that enters the  kerb's cycle.

Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.

In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs  from  glycolysis, heat and  2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.

Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up  in  the body.
