The magnification of the image is × 11

From the formula,

Image size = Actual size × Magnification

Then,

[tex]Magnification = \frac{Image \ size}{Actual \ size}[/tex]

From the question,

The length of the image = 22mm; and

The ant's actual length = 2mm

From

[tex]Magnification = \frac{Image \ length}{Actual \ length}[/tex]

Then,

[tex]Magnification = \frac{22 \ mm}{2 \ mm}[/tex]

Magnification = 11

Hence, the magnification of the image is × 11

The answer is B. Data

A chart showing the amount of rain each month in a region is an example of a scientist's data. Thus, the correct option is B.

What is Scientific data?

Scientific data may be defined as the source of information that is significantly based on research completed by scientists and which has been published in a peer-reviewed journal. This source of data also assists future research based on a specific topic.

Inferences may be defined as the sort of predictions that are usually made before the actual performance of any research. A Conclusion may be defined as the outcome of any research that satisfactorily delivers the evidence to prove the hypothesis.

Variables are those that involve complete methodology on the factors which have to be estimated during an experiment or research.

Explanation:

In peas, yellow pea pods (Y) are dominant to green pea (y) pods. If a heterozygous
dominant male is crossed with a heterozygous dominant female, what is the probability
that the offspring will be green?

Answers

Answer:

In crossing heterozygous pea plants for the color of the pea pods trait, the probability of a offspring with the green pea pod is 25%.

Explanation:

Taking into account that the dominant trait is the yellow pea pod, and that both members of the parental generation are heterozygous (Yy):

Parental generation:

♂ Yy

♀ Yy

Making a Punnet's Square for this crossing:

Yy x Yy

Alleles    Y      y

Y            YY   Yy

y             Yy   yy

In the offspring, the phenotypic probabilities are :

Plants with yellow pea pods (Yy) 50%. Plants with the yellow pea pod (YY) 25% .Plants with green pea pods (yy) 25%.

The Yy:YY:yy ratio is 2:1:1

Why do higher trophic levels in most ecosystems contain fewer organisms than lower trophic levels?

Answers

Answer:

There is less energy in higher trophic levels.

Explanation:

With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels!

The second rule of thermodynamics indicates that some energy is wasted as heat with each energy transfer or transformation, hence higher trophic levels in most ecosystems have fewer organisms than lower trophic levels.

How energy is transferred in the ecosystem?

In an ecosystem, producers like plants use the sun's energy to build organic molecules through a process called photosynthesis. Primary consumers like herbivores then eat these organic compounds. Although the herbivores receive the energy from the organic molecules, some of it is wasted as heat during metabolism along with other biological processes.

The remaining energy is subsequently given to secondary consumers, such carnivores, with part of it once more being lost as heat. The same holds true for higher trophic levels. As we progress up the food chain, the amount of energy available at each trophic level declines, and fewer species can be supported at each higher level.

Therefore, the second rule of thermodynamics indicates that some energy is wasted as heat with each energy transfer or transformation, hence higher trophic levels in most ecosystems have fewer organisms than lower trophic levels.

Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.

Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast.

They lack a nuclear membrane. Mitochondria, Golgi bodies, chloroplast, and lysosomes are absent. The genetic material is present on a single chromosome. The histone proteins, the important constituents of eukaryotic chromosomes, are lacking in them.

People tried to use herbal treatments to cure infection, but this was ineffective. Then, Louis Pasteur discovered that germs would not grow on a certain bread mold. Pasteur's discovery led to the study of antibiotics. For many years, scientists tried to find out why germs would not grow on molds. This process was perfected when Sir Alexander Fleming made a breakthrough in 1928. His discovery was completely by accident. Fleming was known for being untidy. He had left a dish of bacteria out on a table overnight, and it became contaminated with a fungus. Fleming found that this fungus produced a substance he called penicillin. He then just needed to find a way to get the drug to the public. Fleming worked hard for years to make his drug available to large numbers of people. The earliest form of the drug was a powder. The idea was to sprinkle the powder on the wound to treat infection. This did not work often because the drug did not get deep enough into a wound, and the patient would become infected. About fifteen years later, two American companies discovered methods to make the drug on a large scale. They began selling penicillin to the public. Soon, everyone was recovering from bacterial infections, especially the type in wounds. This was good news, too. Nations around the globe had just become involved in World War II.From this article, it is reasonable to infer that A. many soldiers survived infected wounds because of penicillin. B. Sir Alexander Fleming knew and worked with Louis Pasteur. C. the United States is responsible for the discovery of penicillin. D. research is a waste because discoveries are made by accident.
