C. 2KCIO3(s)->2KCI(s)+3O2(g)
D. Mg(s)+2HCI(aq)->H2(g)+MgCI2(aq)

Answers

I believe the correct answer is option A. The equation that has both a liquid and a gas as products is:

2HgO(s)->2Hg(I)+O2(g)

Looking at the state of the products, we have l and g which means for liquid and gas, respectively. This is not exhibited by other choices presented.

A

Reactants are to the left of the arrow and products are to the right of the arrow
(l)=liquid
(g)=gas
(s)=solid

Which coal field location is related to coal fields in the eastern United States and supports the theory of continental drift?eastern India

southern Africa

western Australia

northern South America

Answers

The correct answer is - southern Africa.

The coal fields found in the southern part of the African continent and the eastern part of the United States are a direct evidence that supports the theory of the continental drift. The reason for that is that the coal found in both locations is the same one, from the same type of trees, formed in the same period. All of those clues suggest that the continents were once merged together, as for starters, the type of tree that gave the basic material for the coal is the same, and trees that are totally the same is almost impossible to be found in separated continents as they will have some modifications that will distinguish them. The climate and period in which the coal is formed is also exactly the same, which also leads to the conclusion that there was once a large connected land mass.

As early as the 9th century, it was suggested when organisms change, they may be better ____________.

Answers

Answer:

As early as the 9th century, it was suggested when organisms change, they may be better adapting to survive.

Explanation:

Natural selection, also called Survival of the Fittest, is the process in which the environment influences the fitness of species: organisms that change to adapt better to the conditions they live in, have longer lives and reproduce to leave offspring with the same positive traits.

Two very important people in the development of Evolution Theory are Lamarck (he came up with the theory of acquired characteristics) and Darwin (applied the 'survival of the fittest' to every organism on Earth).

In a car, how does an air bag minimize the force acting on a person during a collision?

Answers

Answer:

It increases the time it takes for the person to stop.

Explanation:

Due to the laws of motion the airbag causes force in the other direction while the person is moving forward, thus trying to equal out the force acting apon the person to make them stay in place.

The wild-type coat color, agouti (AA) is dominant to solid-colored fur (aa). However, a separate gene C, when present as the recessive homozygote (cc), negates any expression of pigment from the A gene and results in an albino mouse. Therefore, the genotypes AAcc, Aacc, and aacc all produce the same albino phenotype. A cross between heterozygotes for both genes (AaCc x AaCc) would generate offspring with a phenotypic ratio of 9 agouti:3 black:4 albino. Which type of gene interaction is thisa. Complementary gene interaction.b. Duplicate gene interaction.c. Recessive epistasis.

Answers

Answer:

This is an example of recessive epistasis.

Explanation:

Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.

The geneticists studying the alien organisms have deciphered their genetic code. For Familiarity, they have used A, C, G, and T to indicate the bases in this code. A comparable genetic sequence in each alien has been identified in the genes that code for eye growth. This genetic sequence has allowed the aliens to be divided into six groups, with the single-tail three-eye group split in half. The geneticists also studied several outgroup species (not shown) to compile a likely ancestral DNA sequence. From this information, they have constructed four possible phylogenetic trees. Based on this genetic information, which phylogenetic tree is most parsimonious? a) phylogenetic tree I b) phylogenetic tree II c) phylogenetic tree III d) phylogenetic tree IV
