Answer:

If a prairie dog had the opportunity to perform an altruistic act (that is, give an alarm call) to help its relatives, the combination of the following relatives would the prairie dog be most likely to help <em>the prairie dog would be equally likely to act altruistically to each of the combinations described.</em>

Explanation:

Altruism is the bedrock of morality, based on this fact. It is obvious that the praire dog would help all because of its altruistic mind and also the genetic link

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released  as  ELECTRONS  move through the first electron transfer chain. This energy pumps HYDROGEN IONS  into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

  1. Luminous energy is trapped by chlorophyll in Photosystem II.
  2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
  3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
  4. <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
  5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
  6. <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
  7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
  8. The released energy is used to produce ATP molecules.
  9. Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.

One group of reptiles, exemplified by the fossil Archaeopteryx, led to the evolution of ________. One group of reptiles, exempli
IrinaK [193]

Answer:

birds

Explanation:

<em>Archaeopteryx</em> is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. <em>Archaeopteryx</em> is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of <em>Archaeopteryx</em> indicates that it was similar to that of nonavian theropod dinosaurs, i.e.,  dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, <em>Archaeopteryx</em> had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.

V125BC [204]

Answer:

Increase

Explanation:

Oligomeric enzyme have more than one polypeptide chain and the enzyme show positive cooperativity. It means that binding of the ligand to the enzyme will help other ligands to bind to the enzyme. Hill cofficient is used to measure the determining the degree of cooperativity of the binding between enzyme and substrate or ligand. As in this case, allosteric enzyme show positive cooperativity, its Hill cofficient will increase
