protons are pumped across the mitochondrial inner membrane as electrons are transferred through the mitochondrial electron trans

If the facts about proton pumping are true, then protons are pumped into the matrix of the mitochondria.

<h3>What causes the electron transport chain's proton pumping?</h3>

Proton pumps are found in the electron transport chain's complexes I, III, and IV. The complexes absorb the energy generated when electrons migrate energetically downward and use it to pump H +start superscript, plus, end superscript ions out of the matrix and into the intermembrane gap.

<h3>when outside of the Matrix are protons pumped?</h3>

At complexes I, III, and IV, the matrix is pumped of protons (2 per complex). The resultant proton gradient drives ATP synthesis: 2 H+ are generated for every ATP. The inner mitochondrion is charged differently due to the proton gradient.

11. If you wanted to obtain 100% roan calves, what would the parents' genotypes need to be?
belka [17]

If you wanted to obtain 100% roan calves, then it si required to cross parents who are homo-zygous (pure lines) for the genes associated with this trait.

<h3>What is a homo-zygous individual?</h3>

A homo-zygous is an individual who has the same gene variants or alleles for a given gene locus.

Conversely, a heterozygous is an individual who has different gene variants or alleles for a given gene locus.

In breeding, pure lines (or purebred) are homo-zygous individuals that may be crossed to obtain the desired trait in the descendence.

For sucrose to be moved from a leaf (source) cell to a root (sink) cell, sucrose is first actively transported into the phloem f
Natali5045456 [20]

Answer:water diffuses into the phloem from the xylem and sucrose moves to the sink

Explanation:Translocation is the movement of ready produced food substances from the site of production to places in the plant where food is needed. such as the roots.the place where food is produced is called the source, the the place where food is used up is called the sink.the leaves are the source in a plant.photsoynthates, which is the plant manufactired food, may move up and down the stem ,majorly to areas of storage and growth.

Surose is the major intermediate product of photosynthesis.it is the form in which sugar is transported.it is conducted by the phloem vessels.this takes place in the long sieve elements that forms the sieve tubes

The high percentage of sucrose in the phloem sap causes water to pass into it from the xylem. This then causes the sap to move from source to sink.

At the sink, sucrose diffuses out of the phloem.it is either stored up or used for growth and repairs

How do ocean currents affect temperature? Check all that apply
zlopas [31]

Answer:

Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.They carry cold water from the poles to the equator and cool air over land.  They move warm water from the equator to the poles and heat air over land.

Explanation:

They carry cold water from the poles to the equator and cool air over land.  They move warm water from the equator to the poles and heat air over land.
