Explanation:
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.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
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 =
11.16%).

What part of the eye dilates and lets in the correct amount of light so
you can see properly
Answer:
The iris is the colored part of your eye. The iris controls the pupil to let the right amount of light into the eye. In bright light, the pupil narrows (constricts) to let in less light. In dim light, the pupil widens (dilates) to let in more light.

A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.
Answer:
The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.
Explanation:
Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.
They are found to be very ardent and quicker at recycling natural waste than animals and plants.
Without adequate moisture, Millipedes can die within 48 hours.

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.

. Which of the following is used to avoid bias in a clinical trial
A) Data manipulation
B) Unfair prejudice
C) Personal interest
D) Double-blind testing
Answer:
D.
Explanation:
Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

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.
What is an ion pump??
Answer:
Active transporters or ion pumps are transporters that convert energy from various sources—including adenosine triphosphate (ATP), sunlight, and other redox reactions—to potential energy by pumping an ion up its concentration gradient.

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.
