Answer:
1. are heterozygous for the disease.
Explanation:
<em>Since the disease causes the death of chicks before hatching, it means that those with the disease cannot be found in the population. In order for the allele of the disease to be passed from generation to generation, there must be parent birds that are carrying the disease in heterozygous state.</em>
Option 1 is the correct option.
Mycorrhizae are associations between fungi and the roots of plants, where the Fungi provides minerals to the plant. It enabled plants and fungi to be the first organisms to invade land successfully 430 million years ago. In most cases the relationship between host plants and the mycorrhizal fungus is mutualistic, or mutually beneficial. The Mycorrhizal fungi come into direct contact with plant roots and with the soil, adding to the plants ability to gather nutrients and water from the soil through the fungus.
Answer:
d
Explanation:
Because you need the cell to become tissue then the tissue Becomes organs then a bunch of organs become a organ system
Answer:
Electron transport chain and ATP synthase
Explanation:
The inner mitochondrial membrane contains an electron transport chain and ATP synthesis. Four membrane protein complexes serve as the electron carriers and are embedded in the inner mitochondrial membrane. These protein complexes are called complex I, II, III and IV. Transfer of electrons from NADH and FADH2 to terminal electron acceptor oxygen occurs via these protein complexes.
During electron transfer, the pumping of protons towards the inner mitochondrial membrane creates an electrochemical gradient. The downhill transfer of protons back to the matrix via proton channel of ATP synthase drives phosphorylation of ADP. Therefore, presence of all the protein complexes of the electron transport chain and ATP synthase is required for electron transfer and ATP synthesis.
