Give examples of how communities or homes reduce pollution.
JulijaS [17]

Some ways would be to use less gas-powered items, such as some stoves. Communities can encourage carpools and walking. If you  were to drive, don't gun the gas and drive at moderate speeds.

In your own home you can conserve energy by turning off lights and electronic devices when not in use.  You could also use energy efficient light-bulbs.

A husband and wife both have cleft chins, and when you look at their four children, three also have cleft chins; however, one do
Reptile [31]

Answer:

B- A cleft chin is due to a dominant allele

Explanation:

A husband and wife both having the phenotype for cleft chin and producing an offspring without a cleft chin, indicates heterozygousity in their genotype.

With the heterozygous genotype however, they both expressed the phenotype for cleft chin, indicating that the allele for cleft chin is dominant over the allele coding for normal chin.

Since both parents are heterozygous for cleft lip, the  sequence of genotype in their offspring will be:

  • 25% chance of having homozygous cleft chin
  • 50% chance of having heterozygous cleft chin
  • 25% chance of having homozygous normal chin

Because of the dominance of the cleft chin allele, both homozygous and heterozygous forms of the cleft chin allele, will be expressed in the offspring and only the offspring homozygous for normal chin will not express this allele.

A piece of granite rock have a density of 2.57g/cm^3 and a mass of 0.304 kg. What is the volume ?
givi [52]

Answer:

1.183×10∧-4 m³

Explanation:

ρ=m/V

Here, m=0.304kg

ρ=2.57g/cm^3 =2570kg/m^3 [1g/cm^3=1000kg/m^3]

V=1.183×10∧-4 m³

Hope, this helps you.
