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.

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]

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).

Which of the following traits are characteristic of all mammals?
A. They breathe through gills.
B. They walk on two limbs.
C. They lay eggs that develop outside the mother's body
O D. The mother feeds her young with her own milk.
Answer:
D
Explanation:
Humans are mammals, so let's analyze the answer choices using this information.
A. They breathe through gills
Humans don't breathe through gills, so this answer cannot be correct.
B. They walk on two limbs
Humans do walk on two limbs, but let's think of other mammals. Cats and dogs are mammals, but they walk on four, not two limbs. Therefore, this answer is not correct.
C. They lay eggs that develop outside the mother's body
Humans don't lay eggs, and neither do other mammals. This is not correct.
D. The mother feeds her young with her own milk.
Humans do feed their young using milk. Nursing their young through milk is a characteristic of all mammals.
The correct answer is D. The mother feeds her young with her own milk.

Do all the red flowers have the same chemical components (pigments). Investigate if the pigments are different or similar in different flowers.
Answer:
The color of the flowers is generally caused by anthocyanin pigments
Explanation:
Anthocyanins are hydrosoluble vacuole pigments from the family of flavonoids. Anthocyanins are characteristics of flowers that have distinct colors depending on the pH (i.e., red, blue, purple, etc). These phytochemicals are commonly present in different parts of the plant including stems, roots, leaves, flowers and fruits.
Carotenoids, another type of phytochemicals, are known to confer their color to tomatoes and carrots. It is a class of isoprenoid pigment that produces yellow and orange colors.
Finally, betalains are another type of glycoside pigments that may also confer color to plants.

Answer:25;
Explanation:
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.
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)
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.
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.
Explanation:
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.

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.
