Answer:
Work done W = 125 N-m
Explanation:
Given:
Force F = 5 n
Distance D = 25 m
Find:
Work done W

Krebs cycle
Electron transport chain
Fermentation
Glycolysis
Answer:
The answer is B- Electron Transport Chain

Stomata are pores in the leaves of plants that allow gases to enter and exit the cells.
During the sunniest part of the day, the leaves are most actively performing photosynthesis.
During this time, which gas do the stomata allow into the leaf cells?
Answer:
carbon dioxide
Explanation:
In most plants, the roots absorb water from the soil. The water travels up through the xylem, a specialized layer of cells. In some plants, the water is absorbed through the leaves, directly from the air. Carbon dioxide, an atmospheric gas, enters the leaf through the stomata, the tiny pores in the leaves (a stoma is a single pore).
true or false: if molecules move from where there is less to where there is more , they move down the concentration gradient

explain how matter behaves differently than energy in a ecosystem
Answer:
Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.
Sea turtles dig holes on coastal
beaches and lay their eggs in the
hole. The mothers then retreat
back to the ocean. Based on this,
sea turtles could be considered
-selected.
A. K
B. S
C.
D. r
r-strategist are species that have large offsprings, but spend no time in parental care. Sea turtles can be considered exaples of r-strategist species.
What are r and k strategists?Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
r strategist species have a high growth rate per capita, and low competition capabilities. This is why they can colonize new environments. But they can not compete with new-established species. r species are often displaced by k species.These species are mostly small-sized organisms with short life cycles. They reach sexual maturity early and have numerous descendants spending no time or energy in parental care.
k strategist species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources.These are big-sized species that live for a long time, reaching sexual maturity in the advanced stages of their lives. They do not have numerous progenies, but they spend time parenting.
r and k strategies are closely related to reproductive strategies, habitat selection, and dispersion ability.
Considering this difference, we can assume sea turtles are r strategist.
They lay several eggs and leave them on the beach. They spend no energy in parenting. Even though they are buried, eggs are still in danger of being attacked by predators.When little turtles emerge, they have to manage to go to to the sea by themselves, being exposed to other predators.The strategy is to spend more energy in laying several eggs to increase survival probabilities, and less energy in parenting.

Answer:
it is the kind of science where scientific knowledge is used to solve criminal cases and other stuff.
benefits:Forensic science technicians can derive deep personal satisfaction from knowing that their work is crucial to solving crimes and achieving justice. They receive respect from the public for their expert knowledge, for example when testifying in court.
limits:Emotional and Physical Effects. Many of the crimes forensic scientists investigate involve violence. As part of their analysis, they may examine bloody clothing, study blood spatter and possibly view victims' bodies. In some cases, the bodies might be severely decomposed.

Which is the following is true about saturated fats?
a. They are typically solids at room temperature.
b. They are generally the healthiest fats to consume.
c. They cannot be broken down by enzymes.
d. By definition, they always contain one or more double bonds.
The following is true about saturated fats: they are typically solids at room temperature, which is in Option A, as they have a high melting point due to the absence of double bonds in their fatty acid chain.
What are saturated fats?Saturated fats are a type of fat molecule that consists of long chains of fatty acids. These fatty acids are called "saturated" because they are fully "saturated" with hydrogen atoms, that is, there are no double bonds between the carbon atoms in the fatty acid chain. This results in a straight, rigid structure that allows these fats to pack tightly together, which is why they are usually solid at room temperature.
Hence, the following is true about saturated fats: they are typically solid at room temperature, which is in Option A.

Why does it hurt when you get kicked in the balls?
Answer:
The first sign of trauma to the testicle or scrotum is most often severe pain. Pain around the testicle may also be due to infection or swelling of the epididymis ("epididymitis"). Because the epididymis has a very thin wall, it easily becomes red and swollen by infection or injury.

Which of the following describes the relationship between photosynthesis and cellular respiration?
A.Only animals carry out cellular respiration, only plants carry out photosynthesis
B.Photosynthesis releases energy from glucose and cellular respiration stores energy as glucose
C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide.
D.Photosynthesis requires oxygen and cellular respiration releases oxygen
Answer:
C.C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide
Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide. Hence, option C is correct.
What is cellular respiration?The process through which organisms use oxygen to break down food molecules in order to get chemical energy for cellular processes is known as cellular respiration. The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration. It takes place in mitochondria and cytoplasm.
Cellular respiration serves the straightforward objective of giving cells the energy they require to function. Food would be completely useless if living beings couldn't obtain the energy they required from it.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen). During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.

Explanation:
Which phases of the cell cycle are included in interphase? Check all that apply.
G1 phase
S phase
G2 phase
mitosis
cell division
Answer:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs.
The interface is the first phase of the cell cycle during which the cell grows to its adequate level to start the duplication of its genetic material, the phases included in interphase are:
G1 phase.The cell physically grows, duplicating its organelles and the proteins needed for subsequent stages.
S phase.A complete copy of the cell's DNA is synthesized, as well as a duplicate of the centrosome, which will help separate the DNA in later stages.
G2 phase.The cell grows even larger, generates new proteins and organelles, and prepares for mitosis, cell division.
Therefore, we can conclude that the interface comprises the G1-S-G2 stages, and during them it grows to its proper level to start the duplication of its genetic material.
