If the half-life of a radioactive atom is 3,500 years. How old is the substance if the parent-daughter ratio is 1:127?
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
Half-life of the radioactive atom (t1/2): 3,500 yearsParent-daughter ratio ([A]/[A]₀): 1:127 (1/127)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
How do gravity and inertia work together in our solar system?
Answer:
They work together to keep things in orbit.
Explanation:
Gravity pulls things in, while inertia says that all celestial objects will try their best to continue forward. The results in the orbiting of celestial objects, like the Earth, around other celestial objects, like the Sun.
Answer:
The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.(Source: sciencing.com)

Tell me a brief summary of what happens in meiosis
**will mark brainliest**
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,
Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.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.
_____________________________________[tex]\huge{\text{Why is Meiosis Important?}}[/tex]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:
During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity.During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'Select the processes that allow water to return to Earth's atmosphere.

evaporation, precipitation, condensation, respiration
condensation, precipitation, evaporation, sublimation
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.

In the United States, there has been an increase in the number of people infected by mosquito spread diseas that were previously found only in countries south of the United States. Scientists want to investigate the cause of the increase in mosquito spread diseases. Scientists have predicted that the mosquitos carrying disease have moved further north as global temperatures have increased. Which questions would help investigate how the new mosquitoes are affecting the ecosystems of the United States ? Select all that apply. AHow much money has been spent to fight the diseases caused by these mosquitoes across the globe? B. How have the food webs in the United States changed as a result of the new mosquitoes? the natural predators to the mosquitoes also migrated north? What types of organisms are preying on the mosquitoes in their new habitats? E Are places in the United States using more pesticides to kill the new mosquitoes? If so, how are these pesticides impacting others in the ecosystems
Answer:
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

Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".
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.

Mention the function of oveary ,ovduct and utterus in the female reproductive system. how essential materials are supplied for the development of foetus?
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.
functions of the fine cytoplasmic filaments
Answer:
Striated, smooth, and cardiac muscle cells contain vast numbers of cytoplasmic filaments that function during the contraction of these cells. ... The contraction of striated muscle cells shortens the muscle, which then moves the skeleton.Define these types of relationships (symbiosis).
a. mutualism -
b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -
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
