Answer:
I would say A but im not 100% sure
Explanation:
The parallax method uses the angle to measure the distance of the objects in space. When the method is used 6 months after then, the star further away changes its position the most. Thus, option A is correct.
What is the parallax technique?The parallax method determines the displacement of the object in the space when viewed from the line of sight and is determined by the angle of the inclination of the shift.
It is used to measure the distance of the planet to the nearby stars and is measured again after six months. It is the change of the position of the object or the celestial body with respect to the observer's position.
Therefore, the star located farthest will change its position the most.

As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis
Answer: Is a result of genetics and environmental factors.
Explanation:
Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.
A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.
Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.
So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

7. To test a new voice feature in a cockpit design a flight simulator was used. The simulator was programmed to
give visual readings of flight information, or to give visual and auditory (voice) readings of flight information. All
test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the
visual, or visual and auditory conditions. Flight experts rated each pilot's performance in the simulator on a
scale of 1 (very poor) to 10 (excellent).
The variables in the simulation procedure carried out are :
Independent variable = Simulator Independent variable = Simulator Dependent variable = PerformanceThe dependent and independent variables are critical in any experimental study as both variables encompasses the variable to be measured and the variables manipulated in other to obtain the variable to be measured.
Independent variable : This is also called the predictor variable which is tweaked in other to obtain changes in the measured or dependent variable. In the experiment performed, the simulator is the independent variable has it has different visual or visual and auditory conditions capable of causing changes to the performance rating. The dependent variable is the variable being measured in an experiment. In this case, it is PERFORMANCE. It is the measured output obtained as the the pilot are being rated based on the simulation.Learn more : https://brainly.com/question/4497530
Forming a hypothesis is the first step of the scientific method.
Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Explanation:
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables

the discovery of isotopes disprove one part of
Dalton's atomic theory
Answer: Because Daltons theory states all atoms of a given element are identical in mass and properties.
Explanation:
The discovery of isotopes demonstrated that atoms of the same element can have different atomic weights, implying that atoms of the same element are not identical in every way.
What is Dalton's atomic theory?Dalton's atomic theory postulated that matter is made up of indivisible particles known as atoms, and that atoms of the same element are all identical and cannot be created or destroyed.
Compounds are formed by the simple combination of atoms into compound atoms.
Dalton, John Experiments with gases became possible at the turn of the nineteenth century, prompting John Dalton to propose a modern theory of the atom based on certain assumptions.
Dalton's theory is debunked. This is because Dalton's theory states that all matter is made up of identical, indivisible, and indestructible atoms. Isotopes have the same element but a different number of neutrons.
Thus, this way, the discovery of isotopes disprove one part of Dalton's atomic theory.

In meiosis, sister kinetochores are attached to the same pole of the cell during meiosis I, and sister chromatid cohesion is released during anaphase II. What would be the likely result if sister kinetochores were attached to different poles of the cell during meiosis I and sister chromatid cohesion was released during anaphase I
Answer:
sister chromatids would migrate to opposite poles in anaphase I
Explanation:
Kinetochores are multiprotein structures that establish the attachment of spindle microtubules to the chromatids during cell division (either mitosis or meiosis). Sister chromatid cohesion at the centromeres refers to the mechanism by which sister chromatids are paired and held together during meiosis I. This process (sister chromatid cohesion) is fundamental to ensure the correct orientation of chromatids on the spindle microtubules and their subsequent segregation in meiosis II. The fusion of sister kinetochores in meiosis I underlies sister chromatid cohesion during this stage of the cell division, thereby their disruption or destruction of sister chromatid cohesion would lead to separation and segregation of sister chromatids to opposite poles of the cell in anaphase I.
According to the ESRT, the rate of temperature increases below the Earth's surface is greatest between depths of
Answer:
Between depths of tectonic plate boundaries and the outer core.
Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.

The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
Answer:
Last choice: ribose; deoxyribose
Explanation:
Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.
Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base: adenine, thymine, cytosine, guanine, and deoxyribose.
Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.

Where is amyglada located in a brain ? How does it function ?
Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.
Explanation
The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).
