Choose one of the two major phases of photosynthesis. Draw a model of that phase that corrects one of the weaknesses in the student’s original model.
Answer:
Choosing light dependent phase of the photosynthesis process.
Explanation:
When the sunlight falls on the leaves of the plant, Light is absorbed by the leaves. The photosystem II captures or traps the photons of the light that leads to electrons of a chlorophyll in excited state with a very large energy charge.
Primary electron acceptor traps the excited electron and simultaneously electrons captured from the water as well. Electrons then move to the PSI (photosystem I) through cytochrome b6f. At the photosystem I these electrons result in the energy imbalance, the electrons that are captured by electron acceptor again that move it to ferredoxin that take them for the production of ATP to ATP synthase.

which structure acts as traffic police in the above passage?
hi friends please answer to this question with the help of give passage in the pic I posted above.. please help me guys..
Answer:
epiglottis
Explanation:
let me give you an activity swallow saliva and see if you breath
a traffic police stops traffic from one end to let traffic on another end pass

Answer: Options are not given, below are the options.
A. Stabilizing effect
B. Intraspecific competition
C. Abiotic factors
D. Interspecific competition.
The correct option is B.
It is intraspecific competition
Explanation:
It is intraspecific competition because the same species of plants are competing for limited available resources.
Intraspecific competition occur between member of the same organism where organism of the same species compete for limited available resources.
A grove of pine trees grows in a cluster around the bank of a lake is an example of intraspecific competition because the pine trees are of the same species and they compete for available limited resources.

Place cells, which are located in the hippocampus, become active in birds when searching for previously-hidden food. Helping them remember where things are, these cells help animals create a:____________
Answer:
Spatial memory
Explanation:
When the need arise to plan and manoeuvre ones way out of a familiar location,or to recollect where particular object is located or an incident happened, the type of memory stored and retrieved from the brain is called Spatial memory.
Generally,animals store information about their environments during their itineraries at different locations,as spatial representation memories of the environments.These are stored in their hippocampus. These are retrieved each time they need to navigate in the environment.
Generally the hippocampus located in the temporal lobes,and medial temporal lobes are the sites where the spatial memory of the environment is stored,and retrieved by the animals(birds)
Generally the hippocampus is the region of the brain which helps to produce ,consolidates,and recollects memories of a specific events in all animals.
What is difference between paranchyma tissues and sclernchyma tissues ?
Answer:
Parenchyma cells are the abundant cells that make up ground tissues in plants.They are flat at point of contact.they have thin primary cell walls and have large vacuoles for storage of food.In leaves they are called mesophyll and are sites of photosynthesis.In other parts they are sites for respiration and protein synthesis.
Sclerenchyma cells are cells with rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.Mature sclerenchyma cells cannot elongate and most of them are dead.

How do you think pollination takes place in flowering plants?
Answer:
My answer is down below.
Explanation:
Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.
Explanation:
insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.

Q23 Which of the following describes the correct relationship between heart sounds and blood pressure? A.Systolic blood pressure is associated with the first heart sound. B. Systolic blood pressure is associated with the second heart sound. C. Diastolic blood pressure is associated with the first heart sound. D. Diastolic blood pressure is associated with the second heart sound.
Answer:
diolostic blood preasure is associated with the second heart sound
Explanation:
Korotkoff sounds are the sounds heard by the health professional who measures the blood pressure with a blood pressure monitor and a stethoscope placed on the patient's brachial artery.
Korotkoff described five types of noise:
* The first sound is a snap corresponding to the systolic pressure. The noise is clear, repetitive on at least two consecutive systoles.
* The second sound is a soft whisper, more or less prolonged, audible between the systolic pressure and the diastolic pressure.

If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered to be older than B. This relative dating technique is based on the principle of Group of answer choices fluorine analysis. paleomagnetism. geolayering. superposition.
Answer:
superposition
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle.
Sediments can be incrusted in horizontal layers in the ground, called stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.
Why are legumes self sufficient when it comes to nitrogen?
A. They have a different way of creating proteins that does not require nitrogen.
B. They have an organic process for using atmospheric nitrogen.
C. They have nitrogen fixing bacteria in their roots that converts nitrogen to nitrates for them.
D. They have bacteria that make them immune to eutrophication.
Answer:
It's c. They have nitrogen fixing bacteria in their roots
that converts nitrogen to nitrates for them.
Explanation:
Legumes are sufficient when it comes to nitrogen because they have nitrogen-fixing bacteria in their roots that convert nitrogen to nitrates for them. Thus, the correct option is C.
What are Legumes?Legumes may be defined as a plant that has fruit or seed, is utilized for food, and belongs to the family of legumes such as pea and bean.
Legumes plants have an excess of nitrogen-fixing bacteria in their roots which assists them with a sufficient amount of nitrogen by converting the organic nitrogen into inorganic nitrates that are easily consumed by plants.
Therefore, the correct option for this question is C.

What process creates mRNA?
Answer:
DNA transcription creates mRNA. Transcription is when information in a strand of DNA is replicated or copied into a new strand of mRNA. The DNA sequence serves as a template for mRNA to be synthesized in the nucleus. mRNA is catalyzed by the enzyme RNA polymerase and requires nucleotide triphosphates as substrates in order to initiate and sustain DNA synthesis.
