Answer:
Sandgrouse is the common name for Pteroclidae, a family of sixteen species of birds, members of the order Pterocliformes. They are traditionally placed in two genera. The two central Asian species are classified as Syrhaptes. How the sand grouse adapt to environment. The dense layer of under down which helps insulate the bird from extremes of heat and cold. The feathers of the belly are specially adapted for absorbing water and retaining it. Allowing adults particularly males to carry water to chicks that may be many miles away from watering holes.

Can someone please help
Answer:
P = 0.79.
Explanation:
To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).
Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.
If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.
To prove this, we can insert these values into the equation:
[tex]0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1[/tex]
[tex]0.6241 + 0.3318 + 0.0441 =1[/tex]
[tex]1=1[/tex]
Describe how incomplete dominance and codominance, two non-mendelian traits, are different from each other.
Answer:
Incomplete dominance occurs when the dominant allele did not completely mask the effect of the recessive allele so that, the recessive allele could manifest some of its traits.Therefore the offspring exhibits some phenotype which reflects the blends of the two traits.( four O'clock flower)
However, in co-dominance(e.g AB blood group) none of the dominant allele is completely dominant over one another.That is the two allele of the same gene are present in the same offspring.Therefore the alleles shows their dominating effects, in the offspring, but no blend of the alleles as in the incomplete allele.

a) The important factor in osmosis is not the number of molecules. Instead, it is the number of particles in a given volume of solution. For example, one glucose molecule dissolved in water yields one particle, but one NaCl molecule can yield two ions: Na+ and Cl-. Water moves osmotically in response to the total concentration of particles in the solution.
If there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water? (1 point)
It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.

Why is variation important for natural selection
Explanation:
genetic variation is important as it allowed natural selection to increase or decrease frequency of alleles already in the population. its also important to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
How do enzymes help digestion?
Answer:
Enzymes are essential for healthy digestion.
Explanation:
There are three types of digestive enzymes depending on the type of food on which they act.
Lipases are those that digest fat. After its breakdown into fatty acids and glycerin, they are synthesized by the pancreas.
Proteases are the ones that break the peptide bonds of proteins, reducing them to organic monomers called amino acids. They originate in the stomach or pancreas.
The so-called amylases break down starches and complex sugars in the diet, by breaking the glucidic bonds, releasing mososaccharides (especially glucose). There are 3 types of amylases: ptyaline, pancreatic amylase, and duodenal amylase.
The benefits of these enzymes are:
- They help digestion and reduce the so-called "acidity".
- They reduce the feeling of bloating and gas.
- Improves the digestion of dairy products.
- Food allergies decrease due to good protein digestion.
- They improve the conditions of hiatus hernia and ulcers.

Predict what the effect of a powerful fungicide that killed almost all fungi have on humans and animals. The plants would no longer have any competition and could provide more food for the animals and humans. The amount of waste would build up and the toxins produced would harm the animals and humans The humans and animals would not have any more parasites that could harm them The ecosystems where the fungi were eliminated would flourish and provide more food for the animals and humans
Answer:
The correct answer is option b. "The amount of waste would build up and the toxins produced would harm the animals and humans".
Explanation:
Fungi play a significant position in the ecosystem as decomposers and reuseable. When fungi consume the waste they encourage those other organisms to consume elements such as phosphorus and nitrogen from decomposing matter.
If a dominant fungicide would kill almost all fungi, the amount of scrap would strengthen up and the toxins constructed would injure the humans and animals.

The daughter plant developed from a zygote. The leaf cells of the daughter plant have 12 chromosomes. The daughter plant is genetically similar to the parent plant. The leaf cells of the daughter plant have 24 chromosomes. The reproduction of the daughter plant involved meiosis.
Answer:
The daughter plant is genetically similar to the parent plant. The leaf cells of the daughter plant have 24 chromosomes.
Explanation:
This is because the type of reproduction that is going on here is asexual reproduction, most likely budding. The chromosome number of the parent is going to be preserved and no sexual reproduction is going to be involved (i.e. gametes and meiosis).

Why are desert landscapes jagged and rocky? There is little chemical weathering to round the landscape. Lack of vegetation causes sinkholes between rock formations. The evaporation process creates angular surfaces.
Answer:
A. There is little chemical weathering to round the landscape.
Explanation:
There is little chemical weathering to round the landscape in desert, primarily because there is significantly small to none water available to cause any weathering of the rocks or other structures in deserts.

What is the role of each of the following in the carbon cycle? Include an example of each. a) Producer b) Primary consumer c) Decomposer
Answer:
Explanation:
Producer- plants like grass
primary consumer- herbivore , like a rabbits
decomposer - earthworms and maggots.
Producer consumes carbon whereas primary consumer and decomposers consumes as well as releases carbon.
Producer takes inside carbon in the form of carbondioxide gas which is used as a raw material in the process of photosynthesis while on the other hand, primary consumer consumes carbon in the form of starch and cellulose by eating producers and releases carbon in the form of carbondioxide in the atmosphere. Decomposer feeds on carbon that is present in the dead bodies of animals and plants which also releases carbon in the form of respiration so we can conclude that producers take inside carbon whereas primary consumers and decomposer releases carbon in the atmosphere.

Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
Answer:
Light microscopes do not magnify at the same level as other options.
The typical light microscope cannot magnify as closely as an electron microscope when looking at some of the world’s smallest structures. Most models are capped at 2,000 times or thereabouts, with some entry-level models offering significantly less to the user. Because the relatively long wavelength of light decreases the ability of the equipment to magnify in the small focus lens, you may not always see everything that is going on with a slide when choosing this option.
