Answer:

2.447 × 10⁴ years

Explanation:

Step 1: Given data

Step 2: Calculate the rate constant

Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.

k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹

Step 3: Calculate the time elapsed (t)

For first-order kinetics, we will use the following expression.

ln ([A]/[A]₀) = -k × t

t = ln ([A]/[A]₀)/ (-k)

t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y

Answer:

In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals.  Food and predators.

First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.

Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.

As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.

Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.

In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.

Explanation:

In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.

We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.

Fire is man made because for there to be fire you have to strike a match or use other man made sources

Answer:

mutualism -Both species benefit

commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.

parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.

predator/prey -One species (the predator) hunts and kills another species (the prey)

competition -The struggle among organisms for the same limited resources in an ecosystem

What types of organisms are preying on the mosquitoes in their new habitats?

Explanation:

I think it is all the answers except for What types of organisms are preying on the mosquitoes in their new habitats? this is because when a new species comes to an area it does not have anything to prey on it

Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,

The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.

Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.

It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:

Answer:

Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through transpiration.

Explanation

They have to realease things somehow

Answer:

- The ovary is the female organ that produces the female gametes

- The oviducts are tubes that extend from the ovaries to the uterus  

- The uterus is an organ that acts to nourish and house a fertilized egg until the fetus is delivered  

- Materials are supplied by the mother's placenta  

Explanation:

The ovaries are the female gonads that function to produce and release female gametes (i.e., oocytes) into the reproductive tract. These organs are also in charge of producing female hormones (e.g. progesterone). The oviducts, also known as fallopian tubes, are a pair of tubes that extend from each ovary to the top of the uterus. The uterus is a thick muscular organ of the female reproductive system that nourishes and houses the embryo and fetus. Finally, materials such as oxygen and nutrients pass from the mother's bloodstream through the placenta which is connected to the fetus by the umbilical cord.

Blood has RBC's, WBC's, platelets and a fluid called plasma. Whereas lymph has WBC's and watery fluid. They both have immune and also circulatory functions in them. One of the major differences between them is that blood flows through blood vessels and lymph through lymphatic vessels.
