Two birds that look very similar to each other have always been considered two distinct species based on differences in their bo

dy size and in where they live. A group of ornithologists studying the two species begins to think they might not be separate species based on observed behavior. What would be the best next step regarding this new hypothesis?

The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.

Answer:

A Genetic structure analysis

Explanation:

An analysis of genetic structure will help to know if these two groups are really different species. For that, some mitochondrial markers could be used first. Mitochondrial markers are used quite frequently for this purpose, since they usually show genetic preferences between different species. This is because they evolve faster than nuclear markers.

<h2>Answer is "long chain fatty acids"</h2>

Explanation:

  • A fatty acid is one of the major components of a triglyceride, which is a form of lipid that is used in the body to store energy. A lipid is just a type of molecule that includes, among other things, fatty acids. Triglycerides are a secondary energy source that the body can use in the event that there is not enough sugar (our primary energy source) in the system. While fatty acids vary in terms of chemical characteristics, they all have some basic qualities in common.
  • Hence the right answer for the fill up the blank is "long chain fatty acids"

Skin color in a certain species of fish is inherited by a single gene with four different alleles. How many different types of g
k0ka [10]

Answer:

4

Explanation:

According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.  

If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.

Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.

Which statement correctly describes the nuclear envelope of a eukaryotic cell? See Concept 6.3 (Page 102) View Available Hint(s)
netineya [11]

The correct answer is: The nuclear envelope is continuous with the endoplasmic reticulum

The nuclear envelope or nuclear membrane is composed of two phospholipid bilayers (outer and inner) that surround the nucleus in the eukaryotic cell. The space between the outer and inner membranes is called the perinuclear space. The nuclear envelop has nuclear pores that are responsible for the transport between nucleus and cytoplasm (e.g. transport of mRNA).

Inga [223]

Answer: The atoms in a gas move at high speed.

The atoms in a gas spread in all directions.  

A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
