The answer is Surgical Contraceptive Methods e.g. Vasectomy(For males) and Tubectomy(Females).

Vasectomy:- In this method vas deference is cutted and tied so that sperms can't reach uthera.

Tubectomy:- In this method both fallopian tubes are cut and tied, so that no egg can head towards the site of reproduction(Cervix).

Note:- Both process are irreversible.

You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they

Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

Dima020 [189]

Answer:

Squamous cell carcinoma presents with a firm, nodular lesion topped with a crust or with a central area of ulceration.

Explanation:

The nurse is providing home care instructions to the client who just had surgery for squamous cell carcinoma. The nurse provides follow-up teaching and explains to the client to watch for squamous cell carcinoma presents with a firm, nodular lesion topped with a crust or with a central area of ulceration. As we know "Squamous cell carcinoma" most generally emerges as a firm, soft, or hyperkeratotic papule either plaque, besides with convenient ulceration.

Why are scientists interested in the origin of organic molecules? help me please...

valentina_108 [34]

Answer:

Gas from Earth's core came to the surface through volcanoes.

Recent hypotheses about the origin of organic molecules suggest that these molecules may have formed in hydrothermal vents deep in the oceans, where hot gases and elements emerge from cracks in Earth's crust.

Which does not occur when ATP is hydrolyzed?

Elena-2011 [213]

I think the correct answer from the choices listed above is the third option. When ATP is hydrolyzed energy is not stored. Rather, it is released. Hope this answers the question. Have a nice day. Feel free to ask more questions.

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern

Keith_Richards [23]

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.

<h3>What are homeotic genes?</h3>

Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
The loss of function of any of the gene changes the body pattern and affects the development.
