Answer: Giant-Impact Theory

Explanation:

There are many theories discussing the formation of moon. One of the most accepted theories is:

Giant-Impact theory which suggests that a Mars sized object collided with the Earth and the debris clumped together due to gravitational force and started orbiting earth which is now the Moon. Thus, the moon has similar composition as the outer portions of the Earth.

What is the expected phenotype of F1 progeny from a cross between two homozygous recessive mutants disrupted in different genese

LenaWriter [7]

Answer:

The correct answer would be - wildtype.

Explanation:

Let assume there are four genes which are :

A-B-C-D

In mutant first, the genotype would be:---a-b-C-D

In the mutant second, the genotype would be:--A-B-c-d

If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.

Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first. This is possible only due to different genes are present in mutants.

Thus, the correct answer is - The correct answer would be - wildtype.

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.

Why is bacteria placed in the kingdom prokaryotes

sukhopar [10]

Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.

Hope this helps! :)
