<h3><u>Answer;</u></h3>

is a relationship between distance and velocity

<h3><u>Explanation;</u></h3>
  • According to Hubble's Law the recessional speed of a galaxy is directly proportional to its distance.
  • <em><u>The Hubble Constant is the unit of measurement used to describe the expansion of the universe, it is the relationship of the recessional speed of a galaxy and its distance.</u></em>
  • The formula showing the relationship is given by the formula:

      v = Hd, where: v = velocity of a galaxy, in km/s. H = Hubble Constant, measured in km/s/Mpc and d is the distance in km.

ADH have which role on kidney? Help please ASAP!
NeX [460]

ADH is also called arginine vasopressin. It's a hormone made by the hypothalamus in the brain and stored in the posterior pituitary gland. It tells your kidneys how much water to conserve. ADH constantly regulates and balances the amount of water in your blood.

How are invertebrates better? PLZ help ASAP
Masja [62]
<span>Invertebrate<span>, </span>any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.</span>
