Answer:

Melting is the process where the atoms of a rigid solid Crystal lattice held by strong bonds, are broken down which increases the degree of locomotion of these atoms which characterises the liquid state.

The energy that breaks these bonds is heat energy ( latent heat of fusion ), hence temperature increases

Luba_88 [7]

Answer:

Hattie has a calculus in her ureter, or kidney stone. Frequent urinary tract bacterial infections, urinary retention, high levels of calcium in the blood, and alkaline urine are predisposing conditions. Her pain comes in waves when peristalsis waves travel at intervals through the ureter. The pain comes when the ureter walls close in during this period on the hard kidney stone

Explain why water used by plants and animals today has been around for millions of years.

Hitman42 [59]

Answer:

All the water that is on earth today is the water that has been on the planet. Freshwater is a million years old. The same water is flowing in a continuous loop in the form of falling as rain and snow from the clouds to the earth’s surface. Running in rivers and ponds. This is due to the water cycle. The cycle where the water evaporates in the atmosphere and is from the atmosphere and then cloud loses the water as rain or snow.

At which position would the skater have the most kinetic energy? Explain your reasoning

Lera25 [3.4K]

At four he is the highest, with the most potential energy, when he reaches 3 he will have the most kinetic energy as he is in the process of turning all the potential energy to kinetic, as he reaches 3 and 2 he loses all the kinetic energy, when he is at one, and not in motion ha has only potential nergy that is un-used.

Within a pedigree, only males exhibit a trait of interest and the trait commonly passes from a male to his grandsons through his

Anni [7]

Answer:

X-linked/Sex-linked recessive inheritance

Explanation:

The most likely mode of inheritance of the trait is an X-linked recessive inheritance.

The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.

During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.

Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait.

The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.
