<h3>Oxidative Phosphorylation</h3>

Explanation:

The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂  through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.

The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the  mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.

The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient  as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.

In humans, the trait for tongue rolling is dominant over the trait for the inability of a human to roll his/her tongue. If a het
MrMuchimi

50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.

Explanation:

Information given:

the ability to roll tongue is dominant, the genotype would be RR, Rr

the inability to roll tongue is recessive trait the genotype = rr

Given that heterozygous male is crossed with homozygous recessive female, the genotype is

Rr X rr

Punnet square shows that:

    R    r

r   Rr  rr

r  Rr  rr    The genotype ratio is 1:1

                 phenotype ratio is 1:1

There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.

What are the helpful measures to conserve human energy??​
GarryVolchara [31]

Answer:

Adjust your day-to-day behaviors

Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.
