The following describes the physical state of the layers of the Earth from the outside to the center- C.solid, partially, melted, liquid, solid

This is the true answer as the outer layer is solid and the inner core is solid.

The Earth's inner core is the Earth's innermost part. It is a solid ball which is composed of an iron–nickel alloy and some other elements.

Hence only option C has these physical states in order.

Naddik [55]

Answer: Life would cease to exist.

Explanation:

The carbon elements is one of the most important elements in the compound that make up living organisms. It is found: in the remains of living organisms; as fossil fuels such as coal, coke and natural gas; as inorganic salts such as carbonates; in water bodies and as gas carbondioxide which makes up 0.03% of air.

Carbon is continuously being circulated in the atmosphere through a process called the CARBON CYCLE. This involves the removal and addition of carbon to the carbondioxide in the atmosphere.

Life would indeed cease to exist if this carbon cycle stops due to the importance of carbon to functioning of living organisms. Important processes which bring about the recycling of carbon between living ( biotic) and non living (abiotic) components of an ecosystem are:

--> photosynthesis: the process used by green plants to remove carbon through carbondioxide from the atmosphere for manufacturing of their food.

--> respiration: animals respire to break down sugar leading to liberation of carbondioxide and water as wastes

--> and decay: decomposers feeds on remains and waste to bring about decay, thus complex carbon compounds are broken down to set free carbondioxide which returns to the atmosphere.

All the above processes are carried out by living organisms to maintain a functioning ecosystem by enabling a linear flow of energy through it.

Anastaziya [24]

Complete question: A phylogenetic tree shows that birds and crocodiles share many features. A hypothesis based on this tree predicts that these features are present in a common ancestor. Which of these predicted traits is supported by fossil evidence?

A) four-chambered heart

B) singing for territory

C) eggs and nests

D) singing to attract mates

Answer: (c) eggs and nests

Explanation:

A hypothesis based on phylogenetic tree shows that birds and crocodiles have ancestral connection. Fossil evidence shows that their common ancestor exhibit oviparity as a means of reproduction (i.e. laying of eggs and embryo develops within the egg), and also housed their eggs in the nest for protection against predators and other important reasons.

In cats, curled ears result from an allele, Cu, that is dominant over an allele cu, for normal ears. Black color results from an

just olya [345]

Answer:

Explanation:

Cross : ggCuCu X GGcucu --------Parents

F1 progeny : GgCucu

Two of the F1 cats mate :

Cross : GgCucu X GgCucu

Gametes :

Gg X Gg = GG, Gg, Gg, gg

Cucu X Cucu = CuCu, Cucu, Cucu, cucu

1/4 GG X 1/4 CuCu = 1/16 GGCuCu (black - curled ears)

1/4 GG X 2/4 Cucu = 2/16 GGCucu (black - curled ears)

1/4 GG X 1/4 cucu = 1/16 GGcucu (black - normal ears)

2/4 Gg X 1/4 CuCu = 2/16 GgCuCu (black - curled ears)

2/4 Gg X 2/4 Cucu = 4/16 GgCucu (black - curled ears)

2/4 Gg X 1/4 cucu = 2/16 Ggcucu (black - normal ears)

1/4 gg X 1/4 CuCu = 1/16 ggCuCu (gray - curled ears)

1/4 gg X 2/4 Cucu = 2/16 ggCucu (gray - curled ears)

1/4 gg X 1/4 cucu = 1/16 ggcucu (gray - normal ears)

Answer : (i). 9/16 black cats, curled ears; 3/16 black cats, normal ears; 3/16 gray cats, curled ears; and 1/16 gray cats, normal ears.

An F1 cat mates with a stray cat that is gray and possesses normal ears :

Cross : GgCucu X ggcucu

Gametes :

Gg X gg = Gg, Gg, gg, gg

Cucu X cucu = Cucu, Cucu, cucu, cucu

2/4 Gg X 2/4 Cucu = 4/16 GgCucu (black - curled ears)

2/4 Gg X 2/4 cucu = 4/16 Ggcucu (black - normal ears)

2/4 gg X 2/4 Cucu = 4/16 ggCucu (gray - curled ears)

2/4 gg X 2/4 cucu = 4/16 ggcucu (gray - normal ears)

Answer : (i). 1/4 black cats, curled ears; 1/4 black cats, normal ears; 1/4 gray cats, curled ears; 1/4 gray cats, normal ears.

List the three laws of Newton in your words. Give an example of each.

OLga [1]

1. For every action there is an equal and opposite reaction

2. Force = mass times acceleration

3. An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by another force.

3. One example is a rock rolling down a hill. You could use a stick or your foot to stop it, but otherwise it would keep rolling

2. An example for law No.2 is pushing a shopping cart. If you push an empty shopping cart, it will go faster than a full shopping cart because the full shopping cart has more mass.

1. One example is a cup on a table. The cup exerts a force down on the table due to gravity, the table exerts an equal and opposite force on the cup to stop it falling through the table

3. use the simulation to observe the first-generation offspring from the cross between flowers c and a. what is the most likely

JulsSmile [24]

To observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck. It can be defined by the following formula: Where P is the probability that an event will occur, A is the number of desired events, and S is the total number of possible events.

With this information, we can observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.
