Explain why natural selection happens to the individual but adaptation happens to an entire population.
Answer:
Natural selection kills a single individual that was weaker/less suited for the environment than the others. Adaption happens to one individual but through breeding, it becomes a trait for the entire species.
Explanation:
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.

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)

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.

Answer:
the 3rd one
Explanation:
Rasheeda made a model of a plant cell and labeled parts of the cell that are not found in animal cells. Which other part of the cell should Rasheeda label
Answer:
Cell wall, chloroplasts, plastids, and a central vacuole.
Explanation:
Rasheeda has to label cell wall, chloroplasts, plastids, and a central vacuole because these parts are not present in the animals cell. The outer boundary of animal cell is cell membrane whereas the outer boundary of plant cell is cell wall. The plant cell has chloroplast due to its function of making their own food with the help of sunlight so that's why it is not present in animal cell which can't make their own food. Plastid is also absent in animals cell and present in plant cell which is responsible for manufacturing and storing of food. Both plant cell and animal cell has vacuole but different in their size and location in the cell.
5. Why are fingerprints stronger individual evidence than nDNA?
Compared to fingerprint evidence alone, DNA was far more likely to lead to suspects and result in arrests. In crime scenes where biological evidence was collected and tested, DNA evidence was five times more likely than fingerprints to yield a suspect and nine times more likely to lead to an arrest.
Select the correct text in the passage.
One way to improve food security is to avoid food spoilage. Identify the correct ways that Devon reduced food spoilage in the passage.
Devon prepared spaghetti and homemade sauce for dinner. The dinner served up to four people, but only Devon was around to eat it. He brought one serving to his neighbor’s house, and stored the other two servings in the refrigerator. Devon ate one more serving of spaghetti the following day. Later that week, his refrigerator broke and the remaining spaghetti spoiled. He immediately called a repair service and got the refrigerator fixed.
Answer:
Explanation:
The dinner served up to four people, but only Devon was around to eat it
Answer:
1.) Devon prepared spaghetti and homes made sauce for dinner.
2.) he brought one serving to his neighbor's house and stored the other two servings in the refrigerator.
3.) he immediately called a repair service and got the refrigerator fixed.
Explanation:
1.) making homemade sauce for dinner he made last time for it to spoil.
2.) by bringing a servant to his neighbor's house made less amount of food that would spoil.

Select the processes that allow water to return to Earth's atmosphere.
evaporation, respiration, sublimation, precipitation
evaporation, respiration, transpiration, sublimation,
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.

Explain how the sun determines climate distribution. What type of weather conditions does the sun control?
Answer:
The rate of energy coming from the Sun changes slightly day to day. It has been suggested that changes in solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes
The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.

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
Explanation:
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
