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.

The cell theory was first proposed in 1838. Evidence obtained through additional scientific investigations resulted in the current cell theory. Which statement describes a component of the original cell theory that was removed because of the new scientific knowledge?
Answer
The correct answer is option D, that is, cell produce through the spontaneous generation.
Rate me please :):)
It is now recognized that life originates from prior life and that cells originate from preexisting cells as a result of experiments and the discovery of the microscope. Thus, option D is correct.
What is original cell theory?All living things are made up of one or more cells, which is one of the three principles of the cell theory. The fundamental unit of structure and organization in organisms is the cell.
While doing studies on tissues in the late 1830s, zoologist Theodor Schwann and botanist Matthias Schleiden proposed the united cell theory.
The unified cell theory states that each living thing is composed of one or even more cells, every cell is the basis of life, and new cells can be created from existing cells.
Therefore, cell produce through the spontaneous generation.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. How would you conduct your investigation? In your answer, explain your independent and dependent variable?
Answer:
The student has observed that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow at a faster rate than they grow in plain soil.

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.

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.
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.

Hope this helps :)
Explanation:
Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.
Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentcan lead to natural selectionalways decreases the size of a populationdoes not affect the frequency of expression of traits in succeeding generations of a populationincreases variation
Answer:
can lead to natural selection
Explanation:
Unequal reproductive success _can lead to natural selection_____.This is because if there is unequal reproductive success then one of the organisms is better suited for reproducing, surviving, and passing down their genes to their offspring rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where individuals better suited for their environment produce more and have better survivality.
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "Nature selected" the better fit organism.
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.
