Answer:
B. Mating must happening randomly
Explanation:
hope this helps! :)
Matting must happen randomly in the population for Hardy- Weinberg equilibrium to occur. Therefore, option "B" is correct.
What is Hardy- Weinberg equilibrium?
Hardy- Weinberg equilibrium states that when in a random matting large population, genotype and the allele frequencies remain constant as evolutionary changes are absent. Influences of other factors are inclusive such as genetic drift, mate selection, bottleneck effect, and founder’s effect.
[tex]p2 + q2 = p2 +q2+2pq[/tex] is known as the Hardy- Weinberg equilibrium equation.
The assumption of the Hardy- Weinberg equilibrium is matting should be sexual only, random matting, and organisms should be diploid.
For the application of the Hardy- Weinberg equilibrium, random matting should stake place.

Which of the following is NOT true about blood typing?
a. It is quicker and less expensive than DNA profiling
b. It identifies the presence or absence of particular proteins embedded in the cell
c. It can provide class evidence to a forensic investigator
d. It can help determine the manner in which a victim died
e. All of the above are true
Answer:
d
Explanation:
The incorrect statement about blood typing is that it can help determine the manner in which a victim died. Information about the cause or manner of a victim's death is usually derived from an autopsy, not blood typing.
Explanation:The statement that is NOT true about blood typing is option d: 'It can help determine the manner in which a victim died'. While blood typing can be particularly useful in forensic investigations for identifying individuals, determining kinship, or excluding individuals as potential sources of biological evidence, it does not provide any information on the manner of death. Detailed information about cause or manner of death is typically obtained through a complete autopsy and not merely by examining blood type.

Explain why it is advantageous for organisms such as fungi and algae to
form mutualistic relationships.
Answer:
Each organism benefits from the other, because each organism provides something the other cannot get on its own.
Explanation:
Fungi and algae form mutualistic relationships because they eat decomposing material and provide protections to other organisms.
Mutualistic relationships between fungi and algae are advantageous because each organism provides a benefit to the other; fungi get nutrients from algae, and algae get a safe environment from fungi. Both organisms can thus survive in environments they otherwise couldn't.
Explanation:It's advantageous for organisms such as fungi and algae to form mutualistic relationships because they each offer something beneficial to the other. In a mutualistic relationship, both organisms benefit. For instance, fungi get photosynthesized nutrients from algae. On the other hand, algae get a safe, moist environment where they can grow, which is provided by the fungi. Through a mutualistic relationship, both algae and fungi can survive in environments where they might not be able to live independently. This type of relationship is a prime example of mutualistic symbiosis at play in the natural world.

When an oceanic plate collides with a continental plate:
A- The oceanic plate is forced beneath the continental plate
B- The oceanic plate is folded into mountain ranges
C- Both plates sink into the fluid mantle
D- Both plates are folded into mountain ranges
When an oceanic plate collides with a continental plate: - A- The oceanic plate is forced beneath the continental plate.
The oceanic plate is subducted under the continental plate due to the high density of the oceanic plate when an oceanic and a continental plate collide.
In this process, the oceanic plate will bend and slide under the other.This happens because the oceanic plate is denser (heavier) than the continental plate.This process is called subduction that forms a deep ocean trench at this subduction boundary.It forms a subduction zone.Thus, When an oceanic plate collides with a continental plate: - A- The oceanic plate is forced beneath the continental plate.

By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn which of the following?
which types of organisms were more common during various time periods
the relative age of different species
how species have evolved over time
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn which types of organisms were more common during various time periods, the relative age of different species, and how species have evolved over time.
Explanation:By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn which types of organisms were more common during various time periods, the relative age of different species, and how species have evolved over time.
Fossils provide solid evidence that organisms from the past are not the same as those found today and show the gradual evolutionary changes over time. By observing the order in which fossils appear in rock layers, scientists can determine the relative age of different species and track the changes in organisms over time.
Final answer:
Comparing fossils from different sedimentary layers enables scientists to understand when certain organisms were prevalent, their relative ages, and evolutionary changes over time using the fossil record and relative dating techniques.
Explanation:
By comparing fossils in higher sedimentary layers with those in lower sedimentary layers, scientists can determine which types of organisms were more common during various time periods, the relative age of different species, and how species have evolved over time. The fossil record is a critical tool for understanding the history of life on our planet, providing evidence for when organisms lived and how they have changed. Relative dating techniques allow scientists to establish the sequence of these changes and correlate the ages of different fossils without knowing their exact ages in years.

Use evidence from the text to support your answer.
10. What can be concluded about the increase of allergies in the future? Use the
evidence from the text to support your answer.
Answer and explanation:
8. What can be concluded from the evidence that coughs and sneezes are natural reflexes and from the evidence that our immune system attacks allergens?
Coughing and sneezing are natural defense mechanisms that consist of the sudden expulsion of air from the respiratory tract, with the intention of expelling any substance harmful to the body.
Allergies are the product of an exaggerated response of the body to the presence of environmental substances, such as dust, fungi and pollen, called allergens. This abnormal response is caused by an immune system previously sensitized to these substances.
Under normal conditions, the immune system is designed to defend an individual against potentially harmful elements. Coughs and sneezes are natural defense mechanisms, which are exaggerated in allergy sufferers.
9. What two possible reasons for the increase in allergies are explained in the passage?
- "Some scientists think our immune systems don't have enough to do ..." "... when our immune system have fewer germs to fight, they can get confused".
According to the excerpt, an immune system that has been inactive due to less contact with germs, looks for a way to attack any substance foreign to the body, which would be a mechanism that promotes the presence of the allergic response.
The confusion of the immune system would be given in some people by reacting in an unusual way to environmental stimuli or food, which do not affect the majority of people.
- ... "weather is warmer for longer periods now, so plants bloom longer .. release pollen, which is a common allergen".
Plant pollen is considered an aeroallergen capable of producing the response with sneezing or coughing in sensitive people.
Other evidence implies an increase in the amount of aeroallergens, as a consequence of the temperature change. A warm temperature for long periods of time promotes flowering in plants more frequently, and there is more pollen dispersed in the environment.
10. What can be concluded about the increase of allergies in the future?
In the text it can be clearly seen how, according to statistical data, the presence of allergies in more people has increased over time.
Many factors may induce an increase in the number of allergic patients in the future, such as the example provided by the passage of children less exposed to germs due to the use of increasingly available medications.
In the past, there were fewer allergies because the immune system remained active to defend the body without the help of drugs.Additionally, the increase in processed food products may be a factor that in the future increases the appearance of allergies in the population. Again, the environmental factor plays a determining role. Over time, many climatic changes occur, which, combined with environmental pollution, may lead to increased allergies in the future.In the images below you will find the information of the article about allergies.
Coughs and sneezes are natural reflexes that help expel irritants while our immune system attacks allergens. The increase in allergies can be attributed to the hygiene hypothesis and genetics. Allergies are expected to continue increasing in the future.
Explanation:The evidence that coughs and sneezes are natural reflexes suggests that they are part of our body's defense mechanisms to expel irritants or pathogens. Similarly the evidence that our immune system attacks allergens indicates that it recognizes them as harmful substances and launches an immune response to protect the body. In the passage two possible reasons for the increase in allergies are explained. The first reason is the hygiene hypothesis which suggests that reduced exposure to pathogens in childhood may lead to an overactive immune response to harmless substances. The second reason is the role of genetics, as allergies can be inherited. Based on the evidence from the text, it can be concluded that allergies are likely to continue increasing in the future. The passage mentions the rise in prevalence and the need for more effective allergy treatments, indicating that the problem is expected to persist.

The theory of plate tectonics is a relatively new idea, developed in the mid-20th century following the discovery of tectonic features on sea-floors. Can you imagine our explanation of faults, earthquakes, mountains, and rifting before the plate tectonic revolution?
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
Explanation:
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Answer:
boom ka boon sorry cant ill try
Explanation:
Plate tectonics has revolutionized virtually every discipline of the Earth sciences since the late 1960s and early 1970s. It has served as a unifying model or paradigm for explaining geologic phenomena that were formerly considered in unrelated fashion. Plate tectonics describes seismic activity, volcanism, mountain building, and various other Earth processes in terms of the structure and mechanical behaviour of a small number of enormous rigid plates thought to constitute the outer part of the planet (i.e., the lithosphere). This all-encompassing theory grew out of observations and ideas about continental drift and seafloor spreading.
In 1912 the German meteorologist Alfred Wegener proposed that throughout most of geologic time there was only one continental mass, which he named Pangaea. At some time during the Mesozoic Era, Pangaea fragmented and the parts began to drift apart. Westward drift of the Americas opened the Atlantic Ocean, and the Indian block drifted across the Equator to join with Asia. In 1937 the South African Alexander Du Toit modified Wegener’s hypothesis by suggesting the existence of two primordial continents: Laurasia in the north and Gondwanaland in the south. Aside from the congruency of continental shelf margins across the Atlantic, proponents of continental drift have amassed impressive geologic evidence to support their views. Similarities in fossil terrestrial organisms in pre-Cretaceous (older than about 146 million years) strata of Africa and South America and in pre-Jurassic rocks (older than about 200 million years) of

Radiation can be absorbed, transmitted, reflected, or scattered.
A good example to understand the nature of radiation is the Sun. The sun's radiation is absorbed, transmitted, reflected or scattered by the earth, in order to thrive and maintain a climate suitable for the habitat.
Absorption is also called the "interaction of light with matter". When this happens, absorption, light is converted into heat energy. This phenomenon can be explained through an example: during summer people avoid wearing black clothing since it absorbs light and gets very hot.

Why do dark-colored shirts get hotter in the sun than light-colored shirts!
Answer:
O A. Dark-colored shirts reflect less radiation.
Explanation:
Darker shirts absorb more heat then the light colored shirts because of the light energy. Dark colored shirts reflect little solar light and heat energy but get hotter in the end.
Due to the light energy, darker shirts absorb more heat than lighter shirts, hence option A is correct.
How do dark-colored shirts get hotter in the sun?Light-colored clothing reflects the majority of visible wavelengths, which reduces heat absorption. Contrarily, clothing that is darker or blacker absorbs more wavelengths and heat, making it warmer to wear.
On the day, you walk, dash to make it to the bus on time, go to lunch, and the shirt ends up soaking all the sunlight.
This light is transformed into different types of energy because it does not just vanish heat enters and is then released.
Therefore, because black clothing is a superb light absorber, it will thus produce more heat the darker it is, hence option A is correct.

It's unlikely for a child at that age to be forgetful of things like brushing their teeth or walking.
Explanation:
If a caregiver notices a preschooler losing previously acquired skills or a slowdown in development, it is crucial to consult with a pediatrician or child development specialist. This could indicate a developmental concern, which could potentially be addressed through early intervention.
Explanation:As a caregiver of a preschooler, if you notice that a child is losing skills they once had or if their development starts to slow down, you should not take this lightly. A range of skills and developmental milestones are associated with certain time frames, and failure to meet these can be an indicator of a potential issue. It is important to consult with a pediatrician or a child development specialist in such cases.
For instance, by the age of 2-3 years, a child starts showing signs of autonomy; they may choose their clothes, food, or toys. If you observe a reversal in such behaviour, it can signal some developmental concern.
Children also display cognitive abilities at certain ages, such as understanding object permanence or realizing certain facts about their environment. Reversal or stagnation in such cognitive abilities could be a cause for concern.
It is therefore important not to ignore such signs, but to communicate and address these through early intervention with specialized professionals. The goal is to promote healthy development and ensure the well-being of the child.
