During ecological succession, why is one type of tree that is short get replaced by taller
tree types?
Answers
Answer:
change in environment
Explanation:
During ecological succession, short type of tree get replaced by taller tree because the environment is in favor of the taller trees. The suddenly and drastically change that occurs in an ecosystem is the main reason for ecological succession. In this ecological succession, the old species becomes vanished and replace by new species which has the ability to survive in that changed environment. The short type of tree get replaced by taller tree because the shorter trees did not get sunlight and nutrients from the soil so tall trees takes their place. The tall trees are more competitive that short trees.

2 hairs from the same head are always morphologically identical. 2 hairs from the same head are always morphologically identical. true false
Answers
It is true that two hairs from the same head will always have the same morphology.
It is possible for two hairs from the same head to have different morphological traits. Through the makeup of its trace elements, hair can be uniquely identified. Humans have unique variations in their hair. Additionally, individual hairs from the same spot on a person can vary. On a person's head, not every hair is identical.
For instance, a suspect may have some gray hairs mixed up with his brown hairs in a head sample. The features of hairs might vary not only from one person to the next but also within a single individual. Hair morphological characteristics that can distinguish human hair can be seen with a rigorous microscopic study.

Explain what Mendel reasoned from the existence of yellow and green seed colors
Answers
Answer: The results of these experiments showed that pea color is controlled by one gene, which has a "green" form and a "yellow" form. If we suppose that a pure-bred green seed plant has two "green" alleles (y) and the pure-bred yellow seed plant has two "yellow" alleles (Y), we can diagram these plants like this.
I Hope This Helps!!!
Mendel considerably reasoned from the existence of yellow and green seed colors that the yellow color (Y) of the seed is dominant over the green color (y). It means that if you want green phenotypes then the genotypes of the offspring must contain both forms of the recessive allele, i.e. yy.
Why Mendel selects the Pea plant in his experiment?Mendel Selects the Pea plants in his experiment because of the following reasons:
It is an annual plant with a short life cycle. So, several generations can be studied within a short period.It has perfect bisexual flowers containing both male and female parts.They produce a large number of seeds in one generation.Pea plants could easily be raised, maintained, and handled during the experiment.Their flowers are predominantly self-pollinating.This demonstration by Mendel directed a revolution and interest in the branch of science which is known as Genetics. It completely changes the theoretical aspect of aspect and gave the concept of dominance.

social class is determined by which two of the following
Answers
Social class is determined by two of the following factors: income and occupation. Social class is a social construct that categorizes individuals into groups based on socioeconomic criteria such as wealth, income, education, and occupation.
Social classes, like other social constructs, are not set in stone but are instead influenced by a variety of factors such as politics, economic policies, and the cultural environment. Social classes are used to stratify society, with people in different classes having varying degrees of access to wealth, power, and influence.
Income is the amount of money a person earns, and it is frequently used as an indicator of social class because it indicates an individual's buying power and financial status.Occupation, on the other hand, refers to the type of work a person performs. Many jobs are related to particular levels of education, and education is frequently seen as an indicator of social class because it is often tied to the socioeconomic status of a person's family and upbringing. Other criteria, such as property, education, and inheritance, also influence social class, but income and occupation are two of the most significant determinants.

Operations performance objectives trade off against each other as the performance of one objective can be improved by compromising on another.
These trade-offs are mostly due to resource constraints, and thus, they are a significant factor in operations management.
What are operations performance objectives?Operations performance objectives refer to the specific outcomes that an operation seeks to achieve. They are the goals of an operation. Organizations use operations performance objectives to create a strategy that addresses the objectives and outlines how to achieve them. Operations performance objectives are split into five categories: Cost: This objective refers to providing a service or product at the lowest possible cost.
Quality: This objective refers to providing a service or product that meets or exceeds customer expectations. Speed: This objective refers to delivering a service or product quickly. Dependability: This objective refers to delivering a service or product as promised. Flexibility: This objective refers to the ability to provide a service or product that meets customer needs. Operations performance objectives trade-offs Operational performance objectives trade-offs refer to the relationship between performance objectives. In operations management, achieving one objective often means sacrificing another. For example, achieving higher quality may mean incurring higher costs, which is a trade-off between quality and cost. In some cases, achieving one objective may enhance another. For instance, a quicker turnaround time (speed) can increase dependability and flexibility. These examples show that trade-offs can be positive or negative. The following are common trade-offs among operational performance objectives: Cost vs. quality: Offering higher quality goods or services will increase costs. Flexibility vs. speed: Being flexible slows down the speed of operations. Speed vs. quality: Higher speed may lead to lower quality. Dependability vs. flexibility: To be dependable, the operations need to be standardized, limiting flexibility.

Straw is an agricultural byproduct consisting of the dry stalks of cereal plants after the grain and chaff have been removed. It makes up about half of the yield of cereal crops such as barley, oats, rice, rye and wheat. It has a number of different uses, including fuel, livestock bedding and fodder, thatching and basket making
How would the supply of straw be affected by an increase in the price of wheat?
A) Movement up and to the right on the supply curve
B) Movement down and to the left on the supply curve
C) Supply increases
D) Supply decreases
Answers
An increase in the price of wheat would lead to a decrease in the supply of straw. This is because farmers would allocate fewer resources to the cultivation of other cereal crops, reducing the production of straw as a byproduct. Therefore, the correct answer is D) Supply decreases.
An increase in the price of wheat would affect the supply of straw by decreasing it. When the price of wheat rises, farmers have a greater incentive to allocate more resources towards growing wheat rather than other crops. Since straw is a byproduct of cereal crops like barley, oats, rice, rye, and wheat, an increase in the price of wheat would lead farmers to focus more on producing wheat, reducing the production of other cereal crops.
As a result, the supply of straw would decrease because farmers are allocating fewer resources to the cultivation of crops that generate straw as a byproduct. This decrease in supply would be represented by a movement down and to the left on the supply curve, as less straw would be available at each price level.
To illustrate this, consider a hypothetical scenario where the price of wheat increases. Farmers, motivated by higher profits, would shift their production towards growing more wheat. This would result in less land, labor, and resources being allocated to other cereal crops, ultimately reducing the overall production of straw. Consequently, the supply curve for straw would shift to the left, indicating a decrease in the quantity of straw supplied at each price level.

Answers
Telescopes use lenses or mirrors to manipulate light paths. Transparent substances follow refraction, while reflective surfaces follow reflection.
Telescopes utilize optical components such as lenses or mirrors to manipulate the paths of light rays. When light rays pass through transparent substances like glass or plastic, they undergo a change in direction due to the phenomenon of refraction. This bending of light follows the law of refraction, which relates the angle of incidence to the angle of refraction.
On the other hand, when light rays encounter reflective surfaces like polished aluminum, they undergo reflection, obeying the law of reflection. The law of reflection states that the angle of incidence is equal to the angle of reflection, with both angles measured relative to the normal of the surface.
In the given lab instructions, the Ray Optics Demonstration Set is used to measure the angles of refraction and reflection and create a graph illustrating the behavior of light rays in each case. By comparing the angles of incidence and observing how they change with increased incidence, students can analyze the behavior of light rays in different optical configurations.

Haemophilia is a genetic condition that impairs people's ability to form blood clots. Some forms of it are known to be sex-linked. Suppose that equal proportions of people are men and women, ignoring further gender variance. One meta-study estimates that 2-in-10,000 men and 1-in-100,000 women have a particular sex-linked form of haemophilia. (a) What is the probability that a randomly chosen person has haemophilia? (b) What is the probability that a given person with haemophilia is a man?
Answers
(a) The probability of a randomly chosen person having hemophilia is 0.000105.
(b) The probability that a given person with hemophilia is male is approximately 1.9.
(a) Probability that a randomly chosen person has hemophilia:
Haemophilia can affect both males and females, but we need to find the probability for both. Hence,
the probability of having hemophilia = probability that a randomly chosen person is male × probability that a male has hemophilia + probability that a randomly chosen person is female × probability that a female has hemophilia
Probability of having hemophilia in males = 2/10,000 = 0.0002
Probability of having hemophilia in females = 1/100,000 = 0.00001
Probability of a randomly chosen person is male = 0.5
Probability of a randomly chosen person is female = 0.5
Probability of having hemophilia = 0.5 × 0.0002 + 0.5 × 0.00001 = 0.000105
(b) Probability that a given person with haemophilia is a man:
From (a), we know that the probability of having hemophilia is 0.000105. Therefore, the probability that a given person with hemophilia is male is:
probability that a given person with haemophilia is a man = probability that a male has hemophilia/ probability of having hemophilia = 0.0002/0.000105 = 1.9048≈1.9 (approximately).
