20. Describe the differences between the respiratory system of frogs and the respiratory system of humans. Your answer
Answers
Answer:
Humans breathe exclusively through their lungs, but frogs use their lungs for only part of their respiration. Frog lungs have thinner walls and are almost like balloons. Both species have bronchial tubes leading to the lungs, but human systems are more complicated, with many branching bronchiole

Answer:
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.

The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.

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:
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.
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.Learn about carbon dating

30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answers
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answers
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.

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.

Plants that reproduce sexually generate seeds. These seeds are often dispersed away from the parent, either through wind , animals , or water. Look at the seed shown in this image of bullrush plants. What form of dispersal do you think it uses, and why ?
Can anyone help me in this question
Help!!!
Answers
Answer:
wind/water either one.
Explanation:
It can reproduce from rhizomes or seed and uses the wind and water to disperse its seeds.
Based on the appearance of the seed shown in the image of bullrush plants, it appears that these seeds are dispersed by wind.
What are different form of seed dispersal?Seed dispersal is the movement of seeds away from the parent plant, allowing them to establish in new locations and increase the chances of survival and reproduction. There are several forms of seed dispersal, including:
Wind dispersal: Seeds with feathery structures or plumes, such as dandelions, are carried by the wind.Animal dispersal: Animals can carry seeds away from the parent plant in their fur or digestive systems, such as berries eaten by birds.Explosive dispersal: Some seeds are expelled from their pods with great force, such as in the case of squirting cucumbers.Water dispersal: Seeds with waterproof coats can float on water and be carried long distances, as seen in coconut palms.Biotic dispersal: Seeds can also be dispersed by other living organisms, such as ants that carry seeds to their nests and bury them there.Learn more about seed dispersal, here:
