Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures

Answers

Answer 1

Answer:

B and D

Explanation:

Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE

Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT

Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE

For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.

Answer 2

The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.

So, option B and D are correct one.

Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE

Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT

Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE

By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct

What is Carbon dating?It is also referred as radiocarbon dating.It is the method used to determine the age of the living organism containing organic( carbon ) based material by using isotopes of carbon which is radioactive.

Qque sensacion experimentas a la boca cuanco tienes ganas i estas delante de un alimento wue te gusta mucho¿

Answers

Answer:

La sensación que experimento en la boca cuando tengo ganas de comer y estoy delante de un alimento que me gusta mucho es la de que "se me hace agua la boca".

Así, al percibir la presencia de un alimento, el cuerpo humano instintivamente comienza a generar saliva en una proporción mayor a la normal, con el objetivo de lubricar la boca y la garganta para facilitar la ingesta de alimentos.  A esta situación se la conoce coloquialmente como "hacer agua la boca".

Which type of rock is shown in each of these photographs?

Answers

Let us see the choices

In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.

Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.

Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.

_______________ and ________________________________ factors can affect an organism’s traits.

Answers

Answer: Genetic makeup and environment

Explanation:

Genetic makeup of an organism is dependent upon the genes inherited from the parents. The genes when express are responsible for the development of specific traits in an organism. The environment is also responsible for contributing to the development of traits in an organism. For example, an organism is able to tolerate the cold environmental conditions and can survive in cold habitat as it has inherited traits from the parents but when exposed to hot environmental conditions then it will adapt to the changes in the environment due to development of heat tolerant trait. Also a person has inherited traits of short height from parents but when provided with nutritious food and performs regular physical activities the person had attained tallness due to environmental factors.

1) Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force.

2) The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.

3) There are the two components of the projectile's motion - horizontal and vertical motion.

4) The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Dr. Flores wants to know which of the forum claims is best supported by the evidence you have gathered from your previous Sim observations and the text. Select the claim you think is best supported from the options below. Claim 1: Molecules in a substance disappear or no longer exist when a substance changes phase. O Claim 2: Molecules in a substance move differently when a substance changes phase. Claim 3: Molecules in a substance change into a new kind of molecule during a phase change.​

Answers

Answer:

Claim 2: Molecules in a substance move differently when a substance changes phase.

Explanation:

Molecules in a liquid phase move freely and bump into each other. In a gas phase, the molecules move with a lot more energy and bump more times against each other; there is a lot of space for the molecules to move. In a solid phase, the molecules hardly move, there is not much space between them, and they are together, often in a regular pattern.

In conclusion, when matter changes from one phase to another, the molecules move differently.

Answer:

you will need to either add or take away energy and pay attention to how the molecules move. Molecules of a solid move in place, molecules of a liquid move around each other, and molecules of a gas move away from each other.

Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

What is oesophagus?

The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.

The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.

The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.

Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

The Board of Ursinus College in Pennsylvania raised its tuition and fees 17.6 percent to $23,460 in 2000. It subsequently received 200 more applications than the year before. The president of the college surmised that "applicants had apparently concluded that if the college cost more, it must be better." Other colleges that raised tuition to match rival colleges in recent years include University of Notre Dame, Bryn Mawr College, Rice University, and the University of Richmond. They also experienced an increase in applications. In contrast, North Carolina Wesleyan College lowered their tuition and fees about 10 years ago by 22 percent and attracted fewer students. The college president concluded that "it didn't work out the way it had been hoped. People don't want cheap." You are hired as a consultant to a President of a liberal arts college in the East. You are asked to evaluate a recommendation by the college's Admissions Director. Susan Hansen, to increase tuition and to reduce financial aid to students. Susan argues that the data from competing colleges suggest that the demand curves for colleges slope upward-the quantity demanded increases with price. Susan projects that the increase in tuition and reduction in financial aid will solve the school's financial problems. Last year, the college enrolled 400 new students who each paid an effective tuition of $15,000 (after financial aid), totaling $6,000,000. She projects that with the increased demand from charging an effective tuition of $25,000, the college will be able to enroll 600 new students (of equal or better quality), totaling $15,000,000.
