In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a

brown horse produces a brown foal. Is the black horse a homozygous or heterozygous for coat color? BB x bb or Bb x bb

Answer:

Bb X bb

Explanation:

  • It is given that the allele B for the black coat is dominant over allele b for a brown coat.
  • A dominant allele always leads to the expression of the dominant trait in the heterozygous condition. 
  • When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait. 
  • Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
  • The cross is shown in the punnett square.

Answer:

Conduction, simply put, is the transfer of heat through matter. ... Hot air rises, but heat flows from hot to cold, regardless of direction. Heat will continue to flow through matter, from hot to cold, until there is no longer a difference in temperature between hot and cold, a condition known as thermal equilibrium

Answer:

root hairs → 1. absorbs water and nutrients from the soil

vascular tissue → 2. consists of xylem and phloem

chloroplast → 3. the site of photosynthesis inside the cell

stem → 4. holds the leaves up high into the sunlight

leaf → 5. acts like an umbrella to absorb light  

terminal bud → 6. the growing part of the stem

taproot → 7. roots that reach deep into the ground

Explanation:

I have been able to match each term to its correct description.

From the above, we will discover that these are parts of a plant. These parts of the plant enable the plant to carry out photosynthesis and to exist.

The root hairs of the plant absorbs water and nutrients from the soil. When such are absorbed, the vascular tissues help to transport them.

The vascular tissue consists of the xylem and phloem. They  transport fluid and nutrients inside the plant. The vascular tissue is associated with two meristems which are the vascular cambium and the cork cambium. It is at the chloroplast that photosynthesis occur; where light energy is converted to chemical energy.

The stem holds the leaves firmly in order to project it to the sunlight. The leaf absorb sunlight which is needed for photosynthesis. The terminal bud is actually the part of the stem that is growing out. Taproot reach deep down the ground in search of water for the plant.

Answer by Mimiwhatsup: Divergent Boundaries. Tectonic plates will slowly move away from the other, the heat from the mantles convection current will crust the plastic making it much way less dense and the less dense material will rise up and will often form a mountain or elevated area of the seafloor.
