If sunlight and a radio wave are both traveling through water, compare the speed of each wave. Explain how you know.
Answer:
Speed of both will be decreases when they travel through the medium of water.
Explanation:
Both sunlight and radio wave has the same speed in vacuum but both speed will be decreases when they travel through the medium of water because the consistency of water is more than air which make hard to travel for sunlight and radio wave. The speed of sunlight is slightly decreases but the radio wave can't go too far in the water and finally stops so we can say that sunlight can travel through water but radio wave none.

What is the function of a pollen tube?
to lead sperm cells into the ovary
to create more pollen
to create sperm cells
to lead egg cells to the sperm cells
Answer:
The function of the pollen tube is to lead sperm cells into the ovary.
Explanation:
In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.
The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.
The other options are not correct because the pollen tube:
Do not create more pollen. Do not create more male spermatophytes. Does not lead the eggs to the male spermatophytes.Answer: to lead sperm cells into the ovary .
Explanation: There needs to be a way for the sperm cells formed by the pollen's generative nucleus to reach the egg cells that are found in the ovary.
2. The experiment proceeded as normal, with the experimental group hearing about the
potential presence of a gun as the confederates left the study and the control group not
hearing about the gun. All participants returned on day two for the interview with the
police detective. After debriefing, none of the participants said they were aware that the
theft was staged. The researchers found that those in the experimental group did
incorporate the gun misinformation into their memories of the theft more than those in
the control condition. That is, the mean score that a gun was present was much higher for
the experimental group (M= 67%, SD = 12.4%) than the control group (M= 33%, SD =

Answer:
Increasing carbon dioxide concentration increases the rate of photosynthesis as carbon dioxide (CO2) is a limiting factor.
Explanation:
Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.
The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.
What is the product and the bubble formation in photosynthesis?The bubbles that are seen in water when plants are kept in light are actually oxygen bubbles. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The oxygen produced during photosynthesis is released into the surrounding environment as a waste product. When plants are submerged in water, this oxygen can accumulate and form bubbles. This process is called bubbling. The bubbles that are seen in the water are an indication that the plant is actively photosynthesizing and producing oxygen.
Hence, she observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.

What cell parts are common to What cell parts are found only in plant cells? What are found only in animal cells?
all of these cells?
Answer:
The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis. What is the composition of a plant cell wall? The cell wall of a plant is made up of cellulose
Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation
Answer: the plant cell has a cell wall, chloroplasts, plastids, and central vacuole structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

2. What fluvial landform is A?
Answer:
The landform marked with A is an ox-bow lake.
Explanation:
In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.
The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

Indicate whether a solution will have more OH– or H+ if the pH value of the solution
is 10.
The solution with a pH value of 10 will have more OH- ions.
In chemistry, pH is described as a scale that is specifically utilized to specify the basicity or acidity of an aqueous solution. The pH of different solutions are described as follows:
Acidic solution: If a solution has pH<7, then the solution is acidic and tend to have more H+ ions than OH- ions Neutral solution: The solution is neutral when pH=7 and the concentration of H+ and OH- ions are the same Basic solution: If a solution has pH>7, then the solution is Basic and tend to have more OH- ions than H+ ionsThus, in this case, pH>7 and thus we can conclude that the solution will have more OH- ions than H+ ions.

Which of the following statements best describes the role of adenylyl cyclase in
the epinephrine signaling pathway?
A.It converts a polymer to its monomer subunits.
B.It moves substances across the plasma membrane.
ect!
C.It accelerates the production of a second messenger.
D.It transfers phosphate groups from to protein substrates.
Answer:
C.It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP), a second messenger that activates the protein kinase A (PK-A) protein by dissociation of its regulatory subunit from the catalytic subunit. The first step of the epinephrine signaling pathway consists of the hormone binding to the epinephrine receptor localized on the cell surface. This binding activates a G protein inside the cell, which in turn activates the adenylyl cyclase enzyme. Subsequently, adenylyl cyclase converts ATP molecules into cAMP molecules. Since cAMP transports the message of the epinephrine hormone within the cell this molecule (cAMP) is considered to be a second messenger. Finally, cAMP activates the PK-A enzyme which phosphorylates different proteins and thus triggers different biological processes.
Describe how positive control in prokaryotes can be altered by the external environment
Answer:
The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.
External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.
In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.
