You are learning about mimicry in entomology. Which microscope would be best to look at the wings of two different butterflies to determine which is a Monarch Butterfly and which is a Viceroy Butterfly?
The greatest tool to use to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly is a scanning electron microscope, hence option C is correct.
What is a scanning electron microscope?A focused stream of electrons is used by an electron microscope known as a scanning electron microscope (SEM) to scan a sample's surface and produce images of the material.
Various signals that reveal information about the sample's surface topography and composition appear as the electrons make contact with the sample's atoms.
The electron beam is scanned using a raster scan pattern, and an image is produced by fusing the position of the beam with the intensity of the signal that is detected.
Therefore, to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly with a scanning electron microscope, hence option C is correct.

Gel electrophoresis allows molecules to migrate along the gel at different rates by using:
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.

how the development of the microscope played an important part in helping to convince people that mendel was right
The microscope can be used to demonstrate the segregation of chromosomes during cell division. The law of segregation of characters is a Mendel's Law.
Each allele or gene variant is located at a specific chromosome location known as a gene locus.
The Law of Segregation indicates how one offspring receives one allele from each parent for each locus in a diploid organism.
The development of microscopy confirmed the idea that offspring receives one allele (which is located at a specific chromosome) from each parent for each gene locus.

Which of the following is a description of a resource that belongs to a country
with a high carrying capacity?
A. Homes are small and house many people.
O B. Food is brought in from other places.
C. Water comes directly from bodies of water.
OD. Food is not always available.
SUBMIT
Answer:
c
Explanation:
cause it comes straight from the creek behind the houses
Carrying capacity defines the population size supported by a region. Water coming directly from water bodies suggests a high carrying capacity. Thus, option C is correct.
What is carrying capacity?Carrying capacity is the quantity of the organisms or the population that can be supported in a habitat without any degradation and damage to the environment. It is a crucial factor in ecology.
It can be high and low depending on the availability of water, food, and space. A high carrying capacity can support a large population than a low carrying capacity because of the abundant resources.
Small homes with large family members, imported food items, and scarcity of food are limiting factors that are not the property of the high carrying capacity, instead, abundant availability of water is the characteristic of the high carrying capacity.
