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?

Answers

SEM scanning electron microscopy

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.

B. Water will enter the cells and cause them to grow in size.
C. Water will neither enter or exit the cells and their sizes will remain the same.
D. Water will enter and exit the cells at a steady rate and their sizes will remain
the same.

Answers

Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.

Explanation:

Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.

Division of cells resulting in the development of an embryo from a zygote happens after fertilization. Therefore, option "A" is correct.

What is fertilisation?

The creation of a single cell known as a zygote by the fusion of a female gamete is egg and a male gamete a sperm. The biological process of fertilization in animals entails the union of a sperm as the male gamete and an egg as the female gamete or ovum.

The three techniques of internal fertilization are oviparity is an egg deposited outside of the female body, oviparity is an egg kept within the female, and viviparity is said to be developed within the female followed by live delivery.

Therefore, fertilization is the first step in the development of the zygote and the development of life.

Explanation:

Mitosis is the only type of cellular division in which number of chromosomes is maintained

What is mitosis?

During the phase of the cell cycle known as mitosis, duplicated chromosomes are physically split in half to form two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Mitosis serves a very vital purpose in living creatures, and one of its functions is the regeneration and replacement of worn-out and damaged tissues. Mitosis contributes to the generation of identical copies of cells and, as a result, assists in the process of healing damaged tissue or replacing cells that have been worn out.

Answers

Explanation:

Why anti-poaching?

Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.

In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.

It is therefore our call to stop the slaughter of rhinos with all our might.

C. 22°C (86°F) with sunny skies
D. 32°C (90°F) with sunny skies

Answers

Answer:

B

Explanation:

jus CS its right

The relative humidity of the air affects how much water vapor it can hold. 30°C (86°F) with cloudy skies would air hold less water vapor than it holds at 30°C (86°F) with sunny skies. So, the correct option is B.

What is Relative humidity?

Relative humidity (RH) measures the amount of moisture in the air compared to the maximum amount of moisture in the air at a given temperature and pressure. It is a standard figure for describing the moisture content of the air and is expressed as a percentage.

At a given temperature and pressure, air is considered to have 100% relative humidity when it contains all the moisture it can hold. The temperature at which the moisture in the air begins to condense into droplets is known as the dew point.

Therefore, the correct option is B.
