Q6.7. During many epidemics, health-care professionals emphasize the importance of

Serga [27]

During many epidemics, healthcare professionals emphasize the importance of community mitigation strategies, such as wearing masks, frequent hand-washing, and social distancing because these strategies help reduce transmission even when drug-based treatments and vaccines are unavailable.

It is of vital importance in cases of epidemics to implement strategies such as:

Hand-washing
Wearing masks
Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to eliminate the presence of a pathogen from the surface of your hands, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a final barrier that the pathogen will rarely be able to surpass, given that most pathogens cannot remain airborne over large distances.

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission until vaccines or drug-based treatments become available and herd immunity can be reached.

Three generations of a family afflicted with hemophilia are illustrated in the pedigree chart family members used the pedigree c

nasty-shy [4]

For the given situation above, I'm afraid I cannot answer your question since a pedigree chart isn't provided along with the question. You can resubmit your question together with the chart and we'll analyze it. Thank you for posting though. Here is what pedigree analysis is about.

Scientists have devised an approach, called pedigree analysis, to study the inheritance of genes in humans. Pedigree analysis is also useful when studying any population when progeny data from several generations is limited. Pedigree analysis is also useful when studying species with a long generation time.

Use what you know about natural selection to fill in the blanks in the hypothesis.It should answer the lab question what is the

Vinil7 [7]

Answer:

The correct answer would be -

If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.

Explanation:

According to the theory of natural selection, an organism that is able to adapt according to the change in the environment, it helps in their survival and increases their number in the system.

It is given that the type of food available is changing, so it will lead to the change in the frequency of bird beaks in that particular area. So, if they adapt to survive under the changes in the available food type, otherwise not be able to survive and die.

So,

If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.

tester [92]

Answer:

Each species has a specific identifying number of chromosomes. For example, a cat, Felis catus, has 38 chromosomes, while corn, Zea mays, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.

Explanation:

Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.

Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.

Genes vary in size and shape. They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.

Each chromosome carries specific genes that code for specific proteins that have specific functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But not all chromosomes carry the same gene sequences. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
