3. How many chromatids do you have?
RUBE

Answer:

1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .

2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

Answer:

Humans , technology , and environment are always interrelated.

Explanation:

To procure nutrition, water, electricity, medications, construction materials, and several other objects, humans must communicate with the environment. Development of science and technology had already allowed us to take advantage of the eco system, but they have also resulted in massive environmental damage and exploits.

Answer:

67%

Explanation:

When taking random samples from a population, the observed numbers are not always as the expected ones. The difference is by chance, instead of 50% heter0zyg0us, the sample included 67%.  

--------------------------

Available data:

-  Moths' color ⇒ diallelic gene

- f(G) 1960 = 0.8

- f(G) 1965 = 0.7

- f(G) 1970 = 0.6

- f(G) 1975 and 1980 = 0.5

-  1980 ⇒ N = 2000 pupae

-  Population in H-W equilibrium

Hardy-Weinberr equilibrium,  

In this problem we assume that the population is under H-W equilibrium, and we know that p = 0.5.

Considering that p + q = 1, then by clearing the equation, we get the value of q = 0.5    

Finally, we know that the genotypic frequency of the heter0zygous genotype is 2pq, so,

F(Gg) = 2pq = 2 x 0.5 x 0.5 = 0.5 = 50%

Now, among the options in the problem, there is not 50% but others. One of them, and the closest to 50%, is 67%.

The chart reflects that through the years, the moth's populations stabilized. Both alleles were favored, and their frequencies got to be equal to each other -0.5-. So there is a high probability of getting heter0zyg0us individuals in the population -50%-, more than any of the h0mzyg0us ones -25%-.  

However, in a natural population, the amount of h0m0zyg0us and heter0zygous individuals observed is not always the same as the expected ones. This fact happens especially when there are random samples.

In this experiment, the researcher took 2000 pupae, but they did not know their genotype. They just took them randomly. Even though the population is in H-W equilibrium, when sampling, the researcher took more heter0zyg0us individuals than the expected ones. It does not mean that the population is not under H-W equilibrium. It just means that by chance, more heter0zyg0us were selected.

So what you need to do in these situations, is to analyze your problem and the provided information, and think about the most feasible answer.

In this case, the expected number is 50% heter0zyg0us. The closest option is 67% and the most feasible. So that would be the answer.

Because the principle of superposisiton states that younger layers of rock will be closer to the surface while older layers of rocks will be father to the surface therefore older

Answer:

energy passing through the water, causing it to move in a circular motion. When a wave encounters a surface object, the object appears to lurch forward and upward with the wave, but then falls down and back in an orbital rotation as the wave continues by, ending up in the same position as before the wave came by.

Explanation:

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. The gravitational pull of the sun and moon on the earth also causes waves.

Answer:

The model is right.

Explanation:

The model made by the students about transform plate boundary is right because in the transform plate boundary, the tectonic plates moves horizontally by rubbing each other. As the tectonic plates rub against each other, huge stresses are created that can cause breaking the portions of the rock that results in earthquakes in that region. The area or regions where these breaking of rocks occur is known as faults. San Andreas Fault in California is the example of transform plate boundary.

When there is no pattern to a population's growth, it is known as stable. The correct option is B.

The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.

The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.

When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.

Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.

Thus, the correct option is B.

Answer:

Hey there,

The answer is A.

This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.

They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.

It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.

It is not C as the mantle is semi molten not solid.

And it’s not D because it’s not a single layer but multiple layers.

So A is the answer.

Answer:

In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Explanation:

Storage, waste disposal and structural support  are the functions of vacuoles, lysosomes, and the cytoskeleton.

The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

Answer: Your correct answer would be both A & B.

Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)

The two correct statements about the geocentric and the heliocentric model are:

The geocentric model

The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model

The heliocentric model:

The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.
