Answer:

Answer number 2

Explanation:

So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.

Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago

Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers

Producers use carbon dioxide in photosynthesis
Alchen [17]

Answer:

Photosynthesis.

Explanation:

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels

Ralph has type B blood and his wife Rachel has type A blood. They are very shocked to hear that their baby has type O blood, and
Cerrena [4.2K]

Answer:

1. The parents genotypes could have been BO and AO

2. wire-hair

Explanation:

There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:

Blood type               possible genotypes

Type A                         AA, AO

Type B                         BB, BO

Type AB                           AB

Type O                              OO

Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO  for them to be able to produce a child with OO. a cross between these two could give rise to OO.

Question 2

Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).

thus, in a cross between homozygous wire haired and smooth haired, we will have:

homozygous wire haired            homozygous smooth haired

P gen              SS                x               ss

F1 gen.                                Ss

phenotype:                     wire haired

I NEED HELP The measure of how resistant a solid is to shape change when a force is applied.
enyata [817]

<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
