In secondary succession, the pioneer species are plants that are adapted to exploit disturbances rather than bare rock. They typically include plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil so other trees and plants can move into the area.

Acetylcholine binds to a GPCR on heart muscle, making the heart beat more slowly. The activated receptor stimulates a G protein,
kogti [31]

Answer:

The correct answer is option (b) "addition of a drug that prevents the α subunit from exchanging GDP for GTP".

Explanation:

The G protein is a name given to a family of proteins that act as a switch in diverse cellular processes, transmitting signals from outside to inside of the cells. When a G protein receptor is activated by a neurotransmitter such as dopamine, the alpha subunit exchanges its GDP for a GTP and disassociates G-protein itself. An addition of a drug that prevents this action would prevent  G protein disassociation, which would enhance the effect of stimulating G protein that acetylcholine does.

What would happen if there were no abiotic factors in an ecosystem?
Brums [2.3K]

Answer:

Plants would be unable to grow and produce oxygen for the animals.

Explanation:

Sunlight, which supports plants, is considered an abiotic factor. If there were no sunlight, plants wouldn't be able to grow, which means no oxygen for many living things found in that specific ecosystem. In other words, that ecosystem would become uninhabitable.

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
GaryK [48]

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.
