in which of these is osmosis occurring
1 plant is absorbing water from the soil
2sugar is being taken up into the blood from the gut
3 water is evaporating from a leaf
4oxygen is entering the blood from the lungs
Answer:
1.Plant absorbing water from the soil.
Explanation:
Osmomsis occurs by the movement of a water from a region of higher concentration of water molecules to a region of lower concentration of water molecules, through a semi permeable membrane,
OR
It occurs as a result of movement of substance molecules from a region of lower concentration to a region of Higher concentration of the substance.
Note: The higher the concentration of the substance molecules,the lower the concentration of water molecules.
The movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.
What is Osmosis?Osmosis may be defined as a type of process through which the movement of a solvent such as water takes place from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane.
The absorption of sugar into the blood from the gut is mediated by secondary active transport with the help of transporters like SGLT-1 and SGLT-2. The process through which water is evaporating from a leaf is known as transpiration. The process of entering oxygen into the blood from the lungs is known as diffusion.
Therefore, the movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.

How does thermal energy affect the earth's layers?
Answer:
The thermal energy of the Earth remains from its formation and is continuously generated from radioactive decay of long-lived radionuclides in the Earths interior. The deeper the Earth layers the higher the temperature with the geothermal gradient of temperatures through the Earth’s crust on average as high as 25–30°C/km.
Explanation:
The thermal energy affect the earth's layers by forming a thermal gradient.
Thermal energy of the Earth:
Deep inside the earth the thermal energy is generated by the radioactive decay of long-lived radionuclides.
This creates a thermal gradient from core to surface of the earth. The temperature of the core is highest, then the manle is semi-solid or liquid.
The crust of the earth is solid and have relatively less temperature,
Therefore, the thermal energy affect the earth's layers by forming a thermal gradient.

Examples of obligate intracellular parasites that can only replicate inside a host cell are:
viruses and prions
rickettsia and viruses
viruses and bacteria
rickettsia and prions
Answer:
rickettsia and viruses
Explanation:
This is because obligate intracellular parasite are parasite that affect humans and they grow, reproduce and survive inside the host cell. These parasite cannot live or survive outside host cell but they live inside host cell, replicate and they depend on the host cell resources i.e the use host cell resources thereby causing harm on the host cell. rickettsia and viruses are parasite that can only survive inside a living organism.
Answer:
rickettsia and viruses

How are rivers made ?
Answer:
Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.
Explanation:
Hope this helps!
Answer:
A river is created when water moves from higher elevation to lower elevation. It usually goes downhill, and can join with other rivers. The river ends when it flows into an ocean.

What are some of the WORST things about coal fuel?
help me please help me
Answer:
Explanation:
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Answer:
Air pollution
Can impact health of citizens like asthma, breathing difficulties, etc.
Can lead to death if not treated or fixed.
Releases greenhouse gases into the atmosphere.
Contributes to global climate change.

Police are investigating a series of murders in which the suspect is leaving little to no physical evidence, such as fingerprints or DNA. They cannot even establish an obvious link between victims. The only real evidence they have are strange pieces of typewritten poetry found tucked into the victims’ pockets. Who might the police call on to give valuable insight to help them identify the perpetrator and possible future victims? Forensic anthropologist Forensic entomologist Forensic pathologist Forensic psychiatrist
Answer:
Forensic anthropologist
Explanation:
Forensics is a branch of science that deals with the solving of crimes. According to this question, police are investigating a series of murders in which the suspect is leaving little to no physical evidence such as DNA or fingerprint. However, strange pieces of typewritten poetry was found tucked into the victims’ pockets as evidence.
Based on this evidence found, a FORENSIC ANTHROPOLOGIST is the person that can give valuable insight to help the police identify the perpetrator and possible future victims. This is because ANTHROPOLOGY is a social science subject that deals with past events, hence, forensic anthropologists will be able to work on the typewritten poetry.

The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.
Explanation:
Mutation Classes
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - CFTR is made in smaller than normal quantities

How does hair help prevent diseases?
Hair plays an important role in our lives. The hair on our head keeps us warm and acts as a cushion for our skull. Hair appearance can also help form our identity and self-image, which makes hair loss very troubling.
Most hair disorders aren’t serious, but they are often considered major cosmetic issues that require treatment. Androgenetic alopecia is the most common form of hair loss, although there are a number of other hair conditions that can affect the scalp and other parts of the body.

A. 1:1
B. 1:3
C. 1:2:1
D. 4:1
The expected genotype ratio is 1:3.
The genotype of an organism is the sum total of the gens that the organism received from its parents. The genotype determines the traits of an organism (phenotype).
Let the dominant gene be R and the recessive gene be r then we have a cross between RR and Rr. The expected genotype ratio is 1:3.
