Answer:

Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

Answer:

Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.

Explanation:

Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.

Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

Answer:

Para comer alimentos sanos y frescos.

Explicación:

Recomiendo a mi familia los alimentos que aún no están vencidos o que son frescos porque los alimentos frescos hacen que nuestra condición de salud sea buena en comparación con los alimentos vencidos. Hay un crecimiento de patógenos como bacterias, hongos, etc.en los alimentos que los hacen dañinos para las personas y causan intoxicación alimentaria en las personas que los consumen, por eso tenemos que ver las etiquetas presentes en los alimentos para verificar su condiciones.

Answer:

where is the question???????????

Answer:

Inherited mutations exist in all cells in the body and somatic mutations only exist in the cell type that mutated. … Somatic mutations are gene mutations that exist in only certain cell types that are mutated, not in every cell in the body and it take place at some time during an individual's life.

Answer:

Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, and other more earthbound elements. In a sedimentary cycle elements move from land to water to sediment. Main reservoirs are the soil and sedimentary rocks.

Answer:

A. 25 weeks

Explanation:

It's the shortest amount of time.

Hope this helps! :)

Answer:

25 weeks

Explanation:

25 minutes would probably be a short term goal. If it takes someone only 25 minutes to do, that would be a pretty short and easy goal. It COULD be 25 weeks.

Answer:

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

Answer:

Both bacteria and archaea have a cell wall that protects them.

Answer: Both bacteria and archaea have a cell wall that protects them. In the case of bacteria, it is composed of peptidoglycan, whereas in the case of archaea, it is glycoproteins and so on.

Answer:

Explanation:

The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

Answer:

D.They carry human waste to treatment facilities away from cities.

Explanation:

Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.

Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.

Answer:

It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)

Explanation:

An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.

Answer:

Rocks

Explanation:

Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the part of the Earth that includes all the rocks, minerals and landforms of the surface and interior that make up the Earth. It starts at the ground and extends all the way down to Earth’s core.

The feature of the Earth that is part of the geosphere is rocks. The correct option is C.

The geosphere is made up of every rock on Earth, from the melting rock beneath the crust to the massive, age-old mountains to the sand grains on the seashore.

The biosphere, a global ecosystem that includes all life on Earth, has a home in both the geosphere and the hydrosphere and lithosphere, etc. Organisms live in both, the geosphere and the hydrosphere.

The geosphere is always moving because the tectonic plates are always moving, and they sometimes collided with each other. The formation of new landmass, volcano eruptions, lava, molten magma, plants and other things, earthquakes, etc. all happened in the geosphere.

Thus, the correct option is C. rocks.

Answer:

The correct answer is ''the total amount of energy an animal uses in a unit of time''

Explanation:

The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

Answer:

The genotype of all children in generation III is Hh. as H comes from dad and h comes from the mother for every case.

yes, their figures should be shaded.

reason :-

The dominant allele Fort this disease is shown by H whereas the recessive trait shown by h.

each offspring in generation III has the genotype Hh

and the presence of one dominant allele is enough to cause the disease.

all children in generation 3 suffer from the disease and so their figures should be shaded

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.

=============================================

For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.

Recall that

distance = rate*time

we can rearrange things to say

rate = distance/time

So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.

----------

So,

rate = distance/time

rate = (260 meters)/(180 seconds)

rate = (260/180) meters per second

rate = 1.44 meters per second, which is approximate

I'm rounding to 3 sig figs.

DNA synthesis

If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2. This self-destruction mechanism ensures that damaged DNA is not passed on to daughter cells and is important in preventing cancer.
