Answer:

Viruses and prions are considered microbes.

Some microbes are visible to the naked eye.

Explanation:

Microbes are the tiny organisms that can not be seen with unaided eyes. However, this does not hold true for all and some microbes like <em>Epulopiscium fishelsoni</em> can be seen with unaided eyes. Bacteria, viruses, protozoans, and prions are some of the microbes. Viruses are the microbes that have a protein coat around their genetic material. Prions are proteins that can cause infections. Prions do not have any genetic material.

Answer: option A and D.

Some microbes are visible to the naked eye. Virus and prions are considered as microbes.

Explanation:

Microbes or microorganisms are small living creatures that are either microscopic (not visible with the naked eye or seen with microscope) or visible to the naked eye when they form colony that are found everywhere. Most microbes are beneficial to man in that they aid digestion of food and decomposition of organic material which serve as fertility to soil. Examples of microbes are Bacteria, fungi, viruses, prions e.t.c.

Though some microbes are pathogens I.e they cause diseases but many microbes are beneficial.

Label the features of the stomach and nearby regions in this frontal section of a cadaver (anterior view)
Fantom [35]
1- Pyloric sphincter
2-Duodenum
3- Bile duct
4-Pancreatic duct
5-Esophagus
6-Lower esophageal sphincter
7-Fundus of stomach
8- Cardia
9-Body of stomach
10-Pyloric part

The <span>esophagus(5) connects to the stomach.</span>
<span> The food passes,from the pharynx, to the esophagus, to the stomach. This process is aided by peristaltic movements done by esophagus muscles.
This organ contains two sphincters:</span><span>the upper and the lower esophageal sphincter.
 
</span>The stomach is divided into four parts:
<span><span>1-The cardia (8) - this part is connected to  the esophagus and its where  the epithelium changes from stratified squamous to columnar.
In this region is the lower esophageal sphincter (6).

</span>2--The fundus(7)- It's formed by the upper curvature of the stomach.

3- the body(9)- is the main part; and the biggest

4-The pylorus/</span><span> Pyloric part (10) - is the lower region. This part is connected to the small intestine, the duodenum. In this region there is a </span>
strong ring of muscle called the (<span>1) Pyloric sphincter.


In the first part of the duodenum there is a connection with a duct that comes from the pancreas -4-</span>Pancreatic duct .
There is another duct that ends in the duodenum called- <span>Bile duct, that caries bile to digest fats.</span>

What is classification? Why is it necessary to classify animals and plants?​
DIA [1.3K]

Answer:

Explanation:

Scientists use Taxonomy, the science of classifying living things, in order to make sense of biodiversity and how living things are related. For example, the classification of species is important in light of a changing environment because it helps scientists keep track of endangered species and what new species were formed because of the environmental change.

When crossing two individuals, the offspring display only one of the two traits found in parents. Which principle of Mendelian g
Kipish [7]

Complete question:

Question: When crossing two individuals, the offspring display only one of the two traits found in parents. Which principle of Mendelian genetics is supported by this observation?

a) segregation

b) independent assortment

c) dominance and recessiveness

d) allele frequency

Answer:

c) dominance and recessiveness

Explanation:

According to Mendel's principle of dominance and recessiveness, the alleles of one gene may be dominant or recessive in nature. When present together, only the dominant allele is able to express itself. Therefore, a hybrid individual for a gene would express only the dominant phenotype. In the given cross, the progeny express only one of the two traits found in the parents. This means that the progeny is heterozygous for the trait and is expressing the dominant trait. The recessive trait is not expressed due to the presence of the allele for the dominant trait.

What happens when a cycle res turns to its starting point
jarptica [38.1K]

Explanation:

Now that we’ve learned how autotrophs like plants convert sunlight to sugars, let’s take a look at how all eukaryotes—which includes humans!—make use of those sugars.

In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration. Cellular respiration extracts the energy from the bonds in glucose and converts it into a form that all living things can use.
