1. The dinosaur and the mammoth existed after the trilobites.

The trilobites are a species that appeared and existed much earlier than any dinosaur or later mammals like the mammoth. The difference in their existence is few hundred million years, and while the trilobites are primitive life form, the dinosaurs and mammoths are much newer, better evolved species.

3. The trilobites and the armored fish died before the dinosaur.

Before the dinosaurs appeared, there were many other species that lived before them, some of which are the trilobites and the armored fish. The trilobites being one of the oldest species, and the armored fish being a more evolved but still primitive fish with exoskeleton. Both of them existed in periods prior to the dinosaur domination.

yKpoI14uk [10]

Answer:

t = ln (N/N°)/(-0.0239)

Explanation :

The decay law is represented as

N = N°e^-kt

Where N is the final number of atom,

N° is the initial number of atoms

k is the decay constant

t is the half-life.

From the above we have,

N/N° = e^-kt

take ln of both sides

ln (N/N°) = -kt

t = ln(N/N°)/-k

At half life, N/N° = 1/2

Therefore, t = (ln 1/2)/-k

t = -0.693/-k

But t = 29 sec

29 = -0.693/-k

k = 0.0239 s^-1

Therefore,

The formula will be

t = ln (N/N°)/(-0.0239)

Electrons are brought to the electron transport system by the oxidation of
Viefleur [7K]

Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.

The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.

NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.

Suppose that in goats, an independently sorting autosomal allele that produces a bearded phenotype is dominant in males and rece
Alika [10]
B+ Bb Ww male × B+ Bb Ww female Because beardedness and coat color independently assort, we can treat them independently. The difference between this cross and a dihybrid cross is that the bearded allele B b is dominant in males and recessive in females. So we deal with male and female progeny separately. For each sex, then, we should get a typical dihybrid ratio. In males, the dominant phenotype is bearded, so we should get ¾ bearded, ¼ beardless. In females the dominant phenotype is beardless, so we should get ¾ beardless and ¼ bearded. Each sex will have ¾ black and ¼ white coats.

In your own word, explain how mutation can benefit a species
makvit [3.9K]

Explanation:

Mutations change an organism's DNA and affect how it looks, how it behaves, and its physiology. A change in an organism's DNA can cause changes in all aspects of its life.

Mutations are essential to evolution; they are the raw material of genetic variation.
