Answer:

a

Explanation:

because it is beneficial in both plant an water

Answer:

(B) No this would not be a symbiotic relationship.

Explanation:

this is because symbiotic relationship is where the two organisms have a mutual relationship where they depend on each other. The plants depend on water for their growth while the water does not depend on anything from the plants.

An example of a symbiotic relationship is between rhizobium bacteria and leguminous plants.The rhizobium bacteria gets shelter and food from the leguminous plants while the leguminous plants use the bacteria to convert nitrogen in the air to nitrates through a process called nitrogen fixation.

In a murder trial, which person testifying to the jury is classified as an eyewitness?

The medical examiner who found poison in the victim's stomach
An expert discussing evidence collected during an investigation
A defendant's best friend, who was out of town when the crime was committed
A person who claimed to see a car of a certain make/model leaving the scene of a crime

Answers

Answer:

A person who claimed to see a car  of a certain make/model leaving the scene of a crime.

Explanation:

Key words to the answer:

"See"

"leaving the scene of a crime."

Eyewitnesses have a firsthand glimpse of events that occurred and they usually have to have seen something that has occurred to be considered a eyewitness, in this case the person who saw the Make/Model of the car that left the crime scene has some claims that can be used to find the criminal and also when the eye witness sees the car they can  tell which direction it went in to give a bit of a clue(although this depends in certain situations). The eye witness  can also be anyone who was anywhere near the crime scene when it happened or even a little bit after it happened.

Answer:

D. A person who claimed to see a car of a certain make/model leaving the scene of a crime

Explanation:

It is D because it would be the closest possible lead for finding who did the crime. Anyone around the time of the murder and anyone going in and out at the time is a suspect, even the eyewitness. If the eyewitness saw someone leaving the location moments before it was reported, that would be suspicious.

(lol among us vibes. it hyped me up for this moment.)

The medical examiner who found poison in the victim's stomach

It would not be this one because they were called after the crime took place, the medical examiner only saw the aftermath of said way to k!ll the person.

An expert discussing evidence collected during an investigation

The expert collected data of the crime scene after it had happened. Otherwise, this would not have been possible. So, they were not an eyewitness since they were not present at the time.

A defendant's best friend, who was out of town when the crime was committed

How would the addressed person out of town see the crime scene? Maybe they were threatened to leave the city? Anyway, it just would not make since for the best friend to be an eyewitness at the time of the crime if they were miles away.

Answers

The two transfers of thermal energy involved in this system are examples of conduction that may include the burner to the bottom of the pot and from the pot to the water. Thus, the correct options for this question are C and D.

What is Conduction?

Conduction may be defined as the process through which heat energy is typically transmitted through collisions between neighboring atoms or molecules. The process of conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.

The mechanism through which heat is transferred from the hot part to the cold part of the body through the transfer of energy from one particle to another particle of the body without the actual movement of the particles from their equilibrium positions is called conduction.

Therefore, the correct options for this question are C and D.

In a partially diploid F′ exconjugant, there are two alleles for lac (1 and 2) and two alleles for his (3 and 4). The phenotype of this cell is identical to a lac 1 his 4 cell. What is the best interpretation?

Answers

Answer:

Explanation:

Lac 1 and his 4 that shows identical phenotype are wild types.

Wild types are the native, the original species or individual of a particular habitat or colony.

Since lac 1 and his 4 are the wild type, lac 2 and his 3 shares the phenotype of Lac 1 and his 4 this because a cross with a wild type will give an individual with a blend of the two gene with phenotype as the wild because they have a dominant gene.

Lac 1 will shows its phenotype when his 4 is also present this is because a cross between the two will give an individual that is phenotypically identical with the parents

Lac 1 and his 4 are dominant.

The given question is incomplete, however, the questions related to this is as follows:

What are the characteristics of the water cycle?

What part do plants play in the water cycle?

Answer:

The correct answer is -

- The characteristics of the water cycle are evaporation, transpiration, condensation, precipitation, surface runoff, and groundwater.

- Plants perform transpiration.

Explanation:

The water cycle is the movement of the water in between different spheres of the earth that include the atmosphere, hydrosphere, geosphere and biosphere. The water cycle has various components and processes that complete the water cycle and connect different spheres.

The components of the water cycle are evaporation of water and transpiration from the hydrosphere or geosphere and plants respectively to the atmosphere. The condensation and precipitation to water again to the geosphere and hydrosphere from atmosphere and runoff on the surface on earth to the water resrvoirs.

What is a major obstacle in cellular respiration? It is limited by the low amount of energy stored in a glucose molecule It is an exergonic reaction, with much of the energy lost as heat, which potentially might damage cells It is an inefficient reaction and doesn’t provide eukaryotic cells with enough energy It requires oxygen to be actively pumped against its concentration gradient into cells

Answers

Answer:

It is an exergonic reaction, with much of the energy lost as heat, which potentially might damage cells

Explanation:

Cellular respiration is an important process carried out by the cells of living organisms in order to supply energy needed for their various cellular functions. Cellular respiration generally involves the breakdown of the stored energy in glucose molecules (in the presence of absence of oxygen).

However, since the process of cellular respiration releases energy as chemical energy (ATP) and majority as heat energy, it is said to be an EXERGONIC REACTION i.e energy-releasing. This hear energy released can damage living cells, which is a major setback to cellular respiration.

An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.

Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.

A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.

Which statement best describes the expected result?

A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.

Answers

Answer:

B: Embedded within the hydrophobic and hydrophillic regions of the bi layer

Explanation:

They are integral protiens and have to be inside

i took a test

This movement aids the cell membrane in preserving its function as a partition separating the interior and exterior cell surroundings. Thus option B is correct.

What is the role of transport protein in fluid mosaic model?

Integral proteins protrude from each end of the phospholipid bilayer and are tucked inside. Larger molecules like glucose can be transported through cell membranes with the aid of integral proteins.

They have sections that match the polarity of the phospholipid bilayer, known as "polar" and "nonpolar" regions.

This movement aids the cell membrane in preserving its function as a partition separating the inside from the outside environments of the cell.

Therefore, in the fluid mosaic model, the transport protein is connected to the phospholipid bilayer's outer layer.

Under normal conditions, gases diffuse through small holes in the leaves of a plant. When the weather is very hot and dry, plants may close these openings to conserve water. How are the closures most likely to affect photosynthesis? O They increase the rate of photosynthesis by increasing the amount of water in the leaf They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf They increase the rate of photosynthesis by increasing the amount of oxygen in the leaf They have little or no effect on photosynthesis because gases do not take part in the process​

Answers

Answer:

They increase the rate of photosynthesis by increasing the amount of water in the plant.

Explanation:

It is hot and dry when these openings close, so the Sun has to be out. Photosythesis is caused when the Sun and water are used by a plant to make food.

The answer to the question should be they increase the rate of photosynthesis by increasing the amount of water in the plant.

A diagram of photosynthesis is below.

The closures that are most likely to affect photosynthesis are they increasing the rate of photosynthesis by increasing the amount of water in the plant. The correct option is A.

What is photosynthesis?

Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.

Photosynthesis depends on some factors. These factors are water, sunlight, and carbon dioxide. If there is a scarcity of any factors, it impacts the process of photosynthesis. If the water does not get enough water, it will dry and there is less chlorophyll for the plant to carry out photosynthesis.

Therefore, the correct option is A. They increase the rate of photosynthesis by increasing the amount of water in the leaf.
