Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient.

Answer:

When high energy electron is passed through electron transport chain, it looses some of its energy.

The complexes associated with the electron transport chain uses some of this energy to pump protons (H⁺) from the matrix towards inter-membrane space.

It leads to the formation of concentration gradient across the inner membrane of mitochondria.

This gradient is used by ATP synthase (located in the inner mitochondrial membrane) for the production of ATP (adenosine triphosphate) with the help of chemiosmosis.

Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission

Dahasolnce [82]

C) all the offspring will be genetically identical.

Explanation:

During binary fission, all the offspring will be genetically identical and little to no variation occurs.

Binary is an asexual form of reproduction which does not involve the combination of gametes from the parents.

During binary fission, the parent simply divides to produce young ones.
In this process, the offspring replicates the genetic component of the parents making it identical.
The offspring is a direct copy of the parents.
It is only in sexual reproduction that genetic materials are exchanged between the parents and offspring. This leads to genetic variation.

If an organism has a diploid number of 6 chromosomes, how many different combinations of maternal and paternal chromosomes are p

Alexxandr [17]

The different number of maternal and paternal chromosomes possible will be 8. that is option A is correct.

Chromosomes are defined as the genetic material within the body. They are thread like structures within the DNA and are made of proteins. In general human body has 23 pairs of chromosomes out of which 22 are numbered while 1 is the sex chromosome. Gametes are genetic material that are generally haploid in nature and they carry only one chromosome along with them. According to the question, there are 6 diploid chromosomes present which means there are 3 pairs of chromosomes. So each gametes will have a total number of 3 chromosomal pairs irrespective of their type that is maternal or paternal. Therefore combination of maternal and paternal chromosomes are given by

Combination = 2ⁿ where n is pair of chromosomes and here n = 3

Combination = 2³ = 8
