OB.
Darwin believed that all organisms were created simultaneously by the force of nature.
C.
Darwin believed that all organisms have descended from two different ancestors.
Answer:
Darwin's theory of evolution declared that species survived through a process called "natural selection," where those that successfully adapted or evolved to meet the changing requirements of their natural habitat thrived and reproduced, while those species that failed to evolve and reproduce died off.

Which statements about light microscopes are correct?
1. To calculate the magnification of a light microscope the eyepiece lens and objective lens magnifications are added together.
2. As the magnification increases the resolution decreases.
3. The resolution of a light microscope is limited by the wavelength of light.
4. The scale on a stage micrometer is resolved more clearly than an eyepiece graticule.

Light Microscope:The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. The resolution of a light microscope is limited by the wavelength of light. Resolution is a somewhat subjective value in optical microscopy because at high magnification an image may appear unsharp but still be resolved to the maximum ability of the objective.Thus, statements 3 and 4 are correct. Therefore option C is right choice.

In '57 Chevy's, the gene for having fuzzy dice (F) on the rear view mirror is dominant
over the gene for having smooth dice (f) on the rear view mirror. The genotype of a
smooth dice is -
FF
heterozygous
ff
cannot be determined
Answer:
ez i just took the test is FF pls give brainly
Explanation:
According to the scenario, the genotype of a smooth dice is ff. Thus, the correct option for this question is C.
What is a Genotype?A genotype may be defined as the ultimate combinations of alleles of those genes which are significantly taken for specific studies in order to determine some facts and knowledge.
According to the context of this question, it is clearly given that the gene for having fuzzy dice (F) on the rearview mirror is dominant over the gene for having smooth dice (f) on the rearview mirror. This means that F>f. So, it the phenotype of a recessive allele has to visualize in any organism, its genotype must carry form forms of the recessive allele.
Therefore, according to the scenario, the genotype of a smooth dice is ff. Thus, the correct option for this question is C.
