Answer:

D

B & C

A

Explanation:

The organism in option D appears only in the outcrop 4 and is not visible in any of the three outcrops. Thus, this organism can be considered as to be least appearing

Hence, option D is correct

The oldest organisms are found at the lowest layer and hence organism in option B and C can be considered as the oldest as they are found in the second most lower layer of their respective outcrops.

Index fossils are the most abundant one. These fossils are easily traceable and must have faced wide range of evolution. Option A fossil is Ammonite which is the most common index fossil known till date

Hence, option A is correct.

Two short-haired guinea pigs have several offspring over the course of a few years. Out of 100 offspring, 25 of them have long h
Llana [10]

The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.

<h3>What is heterozygosity?</h3>

Heterozygous means an organism which has two different alleles of a given gene.

An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;

  • L represents short hair (dominant)
  • l represents long hair (recessive)

Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.

When an automatic battery is fully charged the sulfuric acid and water mixture will have a specific gravity of about
Archy [21]

the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3

the specific gravity of water is -------------------- >1.000 g / cm3.

 The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)

The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer

Why are accessory organs needed for digestion to succeed?.
MakcuM [25]

Answer:

The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal.

Which choice lists the Linnaean taxons in the correct order from least specific to most specific?
Lorico [155]

Answer:

a) Kingdom, phylum, class, order, family, genus, species.

Explanation:

Kingdom is the broadest taxonomic category after domain as proposed by Linnaeus. The Linnaean hierarchy of taxon identifies species as the most specific taxon that include only those organisms that can interbreed to produce the fertile progeny.

Several species with some common features are placed in same genus while related genera are placed in same family. Likewise, related families are placed in same order and the related orders are placed in same phylum.

Hence, kingdom is the least specific or broadest taxon that includes all the related phyla while species is the most specific taxon that include only the organisms that can interbreed.
