Alborosie

Answer:

e. Genes and the environment affect antipredator behavior

Explanation:

Based on the data that was derived from the study we can conclude that Genes and the environment affect antipredator behavior. This is because regardless of the difference in the environment they were reared in both groups fled from the predator which is a genetic trait that has been passed down from generation. Yet, the group reared in low-temperature conditions fled sooner than those reared in high-temperature conditions meaning that the environment has affected the survival and antipredator behavior of the spiders.

Involuntary muscle includes _________.
hodyreva [135]

Answer:

smooth muscle and cardiac muscle only.

Explanation:

because all of these muscles are involuntary meaning all of these muscles are not moveable by choice, you can not decide when to move these muscles. Foe example we can not control the heart muscles, the heart needs to pump involuntary, but the other muscles from the list we have control over. For example we can make a choice when it comes to moving some skeletal muscles, but not a choice when moving smooth muscle and cardiac muscle .

Lesson 01.04 Properties of Water
ryzh [129]

Answer:

1= In living organisms cells are composed of water or we can say that water is one of the important constituent of cells.

2= Hydrogen bonding import man properties to the water such as cohesion, high heat of vaporization, high heat capacity etc.

3= Because of high polarity, all polar substance get dissolve and make it universal solvent.

Explanation:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Hydrogen bond:

The hydrogen bond is the attraction between the toms which already take part in the other chemical bons. The one atom is hydrogen while other may be oxygen, nitrogen or fluorine.

The hydrogen bonding in water import man y properties in it such cohesion, high heat of vaporization, high heat capacity etc. The hydrogen bond hold the water molecules together.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.

The following F2 phenotypic data was obtained from a Drosophila testcross using an F1 offspring. Assume red eye and brown body a
dmitriy555 [2]

Answer:

The genotype of the F1 was wy+/w+y.

Explanation:

One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.

<u>We have two genes with two alleles each:</u>

Red eyes (w+) is dominant over white eyes (w).

Brown body (y+) is dominant over yellow body (y).

The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:

  • wy+/ey (white-eye, brown body): 670
  • w+y/wy (red-eye, yellow body): 650
  • wy/wy (white-eye, yellow body): 38
  • w+y+/wy (red-eye, brown body 56

If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).

Every individual in the offpsring has a <em>wy</em> chromosome, as this was the gamete inherited from the test cross individual.

In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.

Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.
