Answer:

Some protists have one or more flagella, which they rotate or whip: these are typically euglena. Others are covered in rows or tufts of tiny cilia that they coordinately beat to swim—typically paramecium.

Hair pigmentation in mammals follows the generic enzymatic pathway depicted below. Enzyme A synthesizes a black pigment from a p
jenyasd209 [6]

Answer:

Given,

Colourless molecule is converted to black pigment by enzyme A. Black pigment is converted to agouti pigment by enzyme B.

Parent 1: AAbb = Black

Parent 2: aaBB = Colourless

AAbb X aaBB = AaBb (F1) The entire progeny is agouti coloured since dominant alleles for both the genes are present.

When AaBb X AaBb according to dihybrid cross in F2 :

A_B_  = 9 ( Agouti )

A_bb  = 3  ( Black )

aaB_  = 3  ( Colourless )

aabb   = 1 ( Colourless )

Hence genotypic ratio is 9 : 3 : 3 : 1

and phenotypic ratio is 9 (agouti) : 3 (black) : 4 (colourless)

Stage _____ of NREM sleep represents the beginning of actual sleep.
djyliett [7]

Answer: B. Two

Explanation:

     During the first stage, your body starts relaxing and falling into sleep. This is the lightest stage of sleep. You can wake easily during this stage, and are not "fully" asleep.

     During the second stage, your body deepens into it's sleep, your heart rate decreases, your body temperature decreases, and more. <em>This is the stage that "represents the beginning of actual sleep" which is the answer to your question.</em>

     During the third stage, your body is in a deeper state of sleep. Your muscles relax further, your breathing rate slows, and more.

     During the fourth stage, your heart rate and body temperature rise again. Your brain is a bit more active, and your muscles start to "wake up" slowly again.

Nostrana [21]

Answer:

Although each of these strategies is being used to produce fuels, they are ... Algae can produce biomass very rapidly, with some species doubling in as few as 6 h, and ... Microalgae have additional advantages over terrestrial plants. ... The terrestrial models use land that is not presently used for food agriculture. One of the fuel sources of the future is algae, small aquatic organisms that convert sunlight into energy and store it in the form of oil. S. ... Algae could potentially produce up to 60 times more oil per acre than land-based plants. ... In the future, anything that runs on gasoline and diesel could also use biofuel from algae.

If you poke/squeeze/disturb a lepidopteran caterpillar and it produces a y-shaped, odiferous (smelly) osmeteria in response, it
Anna71 [15]

A lepidopteran caterpillar that responds to being prodded, squeezed, or otherwise disturbed by producing a y-shaped, odiferous (smelly) osmeteria is a swallowtail butterfly caterpillar.

<h3>Do Lepidoptera pose a threat?</h3>

In general, moths are calm animals. They just keep to themselves and don't attack or try to harm anyone. In contrast to ants, spiders, and wasps, they do neither bite or sting. They do harm the economy, and having them around the house is certainly annoying.

<h3>Do every caterpillar develop into a butterfly?</h3>

There are numerous caterpillars that change into moths rather than butterflies. There aren't any other exceptions to this rule, though. Every caterpillar will eventually change into either a butterfly or a moth, or both!

<h3>Lepidoptera are they pests?</h3>

Due of their impact as agricultural pests, more species of the taxonomic group Lepidoptera are regarded to be economically significant.
