a small number of finches live in a protected bird sanctuary natural selection is like least likely to occur in this population
Answer:
Natural selection
Explanation:
Answer:
Natural selection is least likely to occur because the birds are living in a protected sanctuary.
Explanation:
A protected sanctuary is important for protected species or "small numbered finches. Protected sanctuaries are made so that almost extinct species can start to repopulate without the effect of any natural selection.
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.

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.

what kinds of bacteria are spherical, endospores,cocci, bacilli, spirilla
The cocci kind of bacteria are spherical in shape. Rod-shaped bacteria are bacilli, and spiral-shaped bacteria are called spirilla. Thus, the correct option is C.
What are the cocci bacteria?A coccus or cocci bacteria is any bacterium or archaeon which has a spherical, ovoid, or generally a round shape. Bacteria are categorized into different classes on the basis of their shapes into three classes which are cocci (spherical-shaped bacteria), bacillus (rod-shaped bacteria) and spiral (two types: spirillum and spirochete bacteria).
Different classes and examples of bacteria are Streptococci, in which cocci are arranged in chains. Example: Streptococcus mutans. Diplococci, in this cocci are arranged in pairs. Example: Neisseria gonorrhoeae. Monococci are single cocci. Staphylococci are the clusters of cocci. Example: Staphylococcus aureus.
Therefore, the correct option is C.

Name one disadvantage of light microscopes
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.

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]
