Answer:

An organism’s phenotype may influence its ability to find food, and also might affect the organism’s ability to reproduce and pass on favorable alleles.

An organism’s phenotype may influence its ability to produce chromosomes and pass those chromosomes to future generations

An organism’s phenotype may influence its ability to turn on certiain genes necessary for survival.

An organism’s phenotype is not connected with the chances for a species to survive.

Phenotype is the physical appearance of an organism as distinguished from its genetic makeup. The phenotype of an organism depends on which genes are dominant and on the interaction between genes and environment.

A 62.6-gram piece of heated limestone is placed into 75.0 grams of water at 23.1°C. The limestone and the water come to a final

alekssr [168]

Answer:

208.7°C was the initial temperature of the limestone.

Explanation:

Heat lost by limestone will be equal to heat gained by the water

$-Q_1=Q_2$

Mass of limestone = $m_1=62.6 g$

Specific heat capacity of limestone = $c_1=0.921 J/g^oC$

Initial temperature of the limestone = $T_1=?$

Final temperature = $T_2$ =T = 51.9°C

$Q_1=m_1c_1\times (T-T_1)$

Mass of water= $m_2=75.0 g$

Specific heat capacity of water= $c_2=4.186 J/g^oC$

Initial temperature of the water = $T_3=23.1^oC$

Final temperature of water = $T_2$ =T = 51.9°C

$Q_2=m_2c_2\times (T-T_3)$

$-Q_1=Q_2$

$-(m_1c_1\times (T-T_1))=m_2c_2\times (T-T_3)$

On substituting all values:

$-(62.6 g\times 0.921 J/g^oC\times (51.9^oC-T_1))=75.0 g\times 4.186 J/g^oC\times (51.9^oC-23.1^oC)$

$T_1=208.7^oC$

208.7°C was the initial temperature of the limestone.

Li Ming thinks that chlorophyll is a reactant of photosynthesis, but her classmate Julian disagrees. Who is correct, and why?

Eddi Din [679]

Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis.

Explanation:

Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis. The reactants in photosynthesis are carbon dioxide and water.

Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight.
In photosynthesis carbon dioxide combines with water to produce glucose and oxygen.
Chlorophyll in plant is a green pigment that is used to trap sunlight during photosynthesis.

PLS HELP ASAP!!!! Describe metallic bonds, include an explanation of their valence electrons. How this related to the properties

Aloiza [94]

If you look it up it will give you plenty of information. This is what I found:

The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. ... When nonmetals bond together, the atoms share valence electrons and do not become ions
