Answers

Answer:

4.

Explanation:

Everyone's DNA is unique unless they are identical twins or if you have some kind of transplant.

Of the following best explains why DNA fingerprints can be used to identify an individual, such as from a crime scene sample it is the situation that Each individual has a unique DNA sequence, with the exception of identical twins. The correct answer is option 4.

What are identical twins ?

These are the babies that are formed from  multiple fusion of gametes and resulting into double fertilization.

DNA is inherited from both maternal and paternal parents. Yes, it is so but the pattern is not same as it will be possible to get the idea of the pattern and analyse along with the prediction of the genome as only few % is predicted.

DNA is used to make proteins during protein synthesis and this situation is clearly correct too but the fact is that this is not helping in the case of DNA fingerprinting where it is not easy to firstly see the DNA pattern then the RNA and then the amino acids and then the proteins.

Scientists have concluded that Tiktaalik lived when deciduous trees began appearing on land, an event that occurred hundreds of millions of years ago. Which radiometric probe (Carbon-14, Iodine-129, Uranium-238) would you choose to determine a more accurate age of the Tiktaalik fossil? Explain your reasoning.


PLEASE HELP ME ILL GIVE 25 POINTS

Answers

Answer:

Carbon

Explanation:

Carbon leaves a bigger footprint when investigating fossils or skeletons scientists use carbon samples.

The Carbon-14 radiometric probe should be used to determine a more accurate age of the Tiktaalik fossil. Radiometric dating is the technique used to calculate the age of fossils.

What is radiometric dating?

Radiometric dating or radioactive dating is a technique which is used to date the materials such as rocks or carbon, in which trace amounts of radioactive impurities were selectively incorporated when they were formed in the fossil such as trees.

Radiometric dating is used to calculate the age in years for a geologic material by measuring the presence of a short-life radioactive element in the fossil. For examples, carbon-14, or a long-life radioactive element plus its decay product which is potassium-14 or argon-40.

Describe how ATP synthase produces ATP.

Answers

Answer:

so it spins the hydrogen molecules to make the ATP

Explanation:

it occurs in the inner membrane of the mitochondria. The electrons drop off the energy and the hydrogen atoms are moving through the Protein channels/pumps. after that the NADH turns into nad+ and the fadh2 turns into fad. these then go back to the citric acid cycle to get the electrons back. (known as electron carriers) the hydrogen molecules get pumped up to the inner membrane space which would be active transport since we are going from low to high concentrations. the hydrogen molecules go down the atp synthase which spins to make the atp. this would be passive transport since its moving from high to low concentrations.

Why did Mendel study pea plants?

They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.

Answers

Answer:

For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.

Why did Mendel choose pea plants to study?

Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.

What was the purpose of the pea plant study?

Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.

Deforestation refers to the loss of forest area worldwide to other uses such as agricultural land, urbanization and mining activities. Deforestation, greatly accelerated by human activities since the 1960s, has adversely affected natural ecosystems, biodiversity and climate.

Several factors, both human and natural, cause deforestation. Natural factors include natural forest fires and diseases caused by parasites that can lead to deforestation. Nevertheless, human activities are one of the main causes of global deforestation.

What is ONE major difference in the problems associated with obtaining measurements on the sizes or densities of animal populations versus plant populations?

Answers

I think one major difference with that is that animals can move around, go distances in search for food or mate, and thus make the animal densities per geography vary greatly. Birds migrate regularly, so their population densities tend to vary with seasons. Their mobility also depends on the availability of food, so animals go away if there are no food in the area.

Plants on the other hand don't move around faster (they can migrate by reproduction: it's their seeds moving around). Thus their densities tend to be more constant per season/life cycle.
