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.

What are the 3 main pros and 3 main cons of climate change ? and explain why they are a pros and a cons.
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.
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.

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.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen

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.
. 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.
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%).

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.

Below is a sequence from a template strand of DNA. Write the sequence of the mRNA that would be transcribed from this. Be sure to label the 3’ and 5’ ends.
DNA:3’ A G G T C T T C A C 5’
mRNA:
Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

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.

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.
