4. A woman pushes a stroller with a force of 8.2 N and performs 28.7 J of work on the stroller. Over what distance was the
Force applied?
Answer:
3.5m
Explanation:
Given parameters:
Force applied = 8.2N
Work done = 28.7J
Unknown:
Distance through which the force was applied = ?
Solution:
Work done is the force applied on body to move it through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
28.7 = 8.2 x distance
distance = 3.5m
Carbon, nitrogen, and phosphorus are examples of nutrients that organisms need to stay alive. Nitrogen can be the Choose... in an ecosystem when its available forms are in short supply.
Answer:
Nitrogen is present in the soil in the form of ammonium and nitrates.
Explanation:
Nitrogen present in large amount in the atmosphere about 78 % by volumes but in an ecosystem such as land and water its available forms are in short supply because very less amount of nitrogen is produced due to the process of decomposition and some quantity of nitrogen comes from the atmosphere with the rainfall and mixes with soil and present in the soil in the form of ammonium and nitrates.

Imagine that four genes on a single chromosome in a mutant phenotype of Drosophila cross over at half the normal rate as in the wild-type phenotype. How, if at all, would genetic maps of that chromosome differ between this mutant and the wild-type fly
We know that frequency of recombination is proportional with the distance between the genes on the chromosome. Therefore when the recombination rate is higher that means the distance between the genes on the chromosome is bigger. If the recombination rate is lower that means the genes are closer to each other on the chromosome. In this case the cross over rate is half the normal rate in the wild-type. That means that on the genetic map the distance between the two genes on the wild type will be twice bigger than the genes of the mutated Drosophila.
What is the function (purpose) of the valves which connect the heart chambers?
allows blood to flow between the two atria
allows blood to flow from the atria to the ventricle
prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles
Answer:
allows blood to flow between the two atria
allows blood to flow from the atria to the ventricle
prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles
prevents blood from flowing into the atria when ventricle pumps
The valves allow the blood to flow in only one direction so for example when the left ventricle contracts the mitral valve prevents the blood from going back into the left atrium.

Which of the following is not a true statement about seed bearing plants?
The wind and animals can plant the seed in different locations.
Some seed bearing plants produce flowers.
Seed bearing plants produce spores.
Some seed bearing plants produce cones.
Answer:
Seed bearing plants produce spores is not a correct statement.
Explanation:
The plants have different mechanisms of reproduction. The more primitive plants, for example, tend to reproduce through spores that are dispersed over a wide area by the wind. The plants that evolved later in history tend to produce seeds through which they reproduce, and the seeds can be dispersed in numerous different ways.
Some of the plants that bear seeds produce flowers, some fruits or vegetables, while some cones. The reason why they produce such things is to be more attractive for animals because by eating or getting near them the animals manage to disperse the seeds over a wide area. The plants of this type that have the smallest seeds don't really need animals though, as the wind is able to easily pick up and move their seeds around with ease.
Answer: best guess: A. The wind and animals can plant the seed in different locations.

Which of the following is found in both cellular respiration and
photosynthesis?
A. Glycolysis
B. The Calvin Cycle
C. The Krebs Cycle
D. Electron transport chains
The process found in both cellular respiration and photosynthesis is Electron transport chain.
Photosynthesis is the process whereby green plants obtain their food using energy from sunlight. Cellular respiration is the process whereby living organisms obtain energy by breaking down food molecules in their cells. Photosynthesis occurs in the chloroplast organelle where a process called electron transport chain (ETC) synthesizes ATP (energy). The process of ETC occurs in the mitochondria organelle, which is the site of cellular respiration. Therefore, process found in both cellular respiration and photosynthesis is Electron transport chain.Learn more at: https://brainly.com/question/13721588?referrer=searchResults
How do minerals enter root cells from surrounding soil
Answer:
Absorption of mineral elements by the root from the soil takes place by active transport. The water film around the soil particles also contains a low concentration of mineral elements. These mineral elements move from soil into the root cells against the concentration gradient.
Answer:Root cells contain proton pumps that actively expel H+ ions stored in the vacuole of root cells
into the surrounding soil.

How do police use DNA to try and solve crimes? Do you think city police departments should make their own DNA databases? Explain why or why not. Back up your answer with facts and details from the Article.
Answer:
Police matches the DNA with the criminal present in their database.
Explanation:
Police use DNA that are collected at the site of crime in order to solve crimes because the criminals DNA are mostly found at the site of crime. the police collected these DNA and search in their database where the DNA of all the criminals are present. if the DNA matches with the criminal present at the database so it means that this criminal commit this crime so it is arrested and further investigation will be held. Yes, city police departments should make their own DNA databases in order to solve the case quickly.

what is budding in plants
Answer:
Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. In the budding process, a bud is taken from one plant and grown on another. Although budding is considered a modern art and science, grafting is not new.

Help me with this question plsssss answer this in a complete paragraph
Answer:
It's possible.
Explanation:
It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.
Do red blood cells cause blood clots? And how/why?
Answer:
yes
Explanation:
RBCs are involved in platelet‐driven contraction of clots and thrombi that results in formation of a tightly packed array of polyhedral erythrocytes, or polyhedrocytes, which comprises a nearly impermeable barrier that is important for hemostasis and wound healing.
Answer:
Red blood Cells Cause clots because->
Explanation:
Cholesterol builds up in certain parts of the body and blood gets stuck on these piles of Cholesterol. Soon Cholesterol piles up and as more blood cells get stuck, the vein gets clogged.

explain digestion Process
Answer:
Digestion is the process of converting complex food any individual eats, into the smaller components and nutrition that is absorbed and assimilated into the body to produce energy and nutrition for the cell and body. The digestion process takes place in the digestive system that includes the gastrointestinal tract and organs like the liver and pancreas.
It includes ingestion of food through the mouth or buccal cavity, propulsion of food, physical digestion by making it small pulp with help of peristalsis, chemical digestion by the enzymes and acid, absorption through the intestine into the blood, and defecation of waste.
