n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr

A newly discovered animal reproduces slowly. It has only one offspring each time it reproduces. Which reproductive strategy does

Marizza181 [45]

Answer:

C: K Strategy

Explanation:

The best choice will be C- K strategy because this type of strategy involves greater investment from parents into their offspring. These organisms are mostly higher organisms which reproduce slowly and ensure the maximum survival of their offspring. They compete strongly with other organisms and invest more in their survival by producing fewer quality offspring that have more survival opportunities.

Example of K-selected species include larger mammals (such as primates and horses), birds and larger plants. Unlike their opposite R-selected specie which produce large number of offspring, K selected specie are called in Equilibrium wile R-selected species are called as opportunistic.

Inhibitors of the electron transport chain exert their effects through a variety of mechanisms.

Vladimir [108]

Answer:

Azide and Carbon monoxide block electron transport and proton pumping via inhibition of Complex IV.

Rotenone blocks electron transport and proton pumping via inhibition of Complex I.

Atractyloside blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.

Explanation:

The mitochondrial electron transport chain is composed of different complexes integrated into the inner mitochondrial membrane, which function to generate an electrochemical proton (H+ ions) gradient that is then used to drive the synthesis of ATP, the energy coin of the cell. The mitochondrial complex I catalyzes the electron transfer from nicotinamide adenine dinucleotide (NADH) to ubiquinone and then transports H+ ions across the inner mitochondrial membrane. Moreover, the mitochondrial complex IV, also known as Cytochrome c oxidase, receives electrons via the cytochrome pathway in order to complete the reduction of oxygen (O2) into two molecules of water (H2O). Azide is a selective inhibitor of the complex IV which acts as an uncompetitive inhibitor with regards to O2, while carbon monoxide (CO) binds to the cytochrome c oxidase enzyme, thereby suppressing its activity and thus disturbing ATP synthesis. Rotenone is a potent inhibitor of the mitochondrial complex I that inhibits electron transfer from the iron-sulfur centers in the complex I to ubiquinone, thereby blocking ATP synthesis. Finally, atractyloside is a competitive inhibitor that inhibits the transport of ADP across the mitochondrial inner membrane by blocking the ADP/ATP translocator, thereby preventing ADP from entering mitochondria.
