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.

Name and explain the archetypes illustrated in the myth of Cupid and Psyche.
Answer:
Underneath is provided the archetypes depicted throughout the Cupid as well as Psyche myths.
Explanation:
The Cupid as well as Psyche myth seems to be an illustration of many other archetypes. Initially, it seems to be using the Tasks as well as Tests particular circumstance archetype something which Psyche should therefore accomplish. Psyche herself would be an instance of both the individual Ingénue and perhaps Maiden. She also seems to be naturally beautiful and then becomes a smart teenage girl. Venus has always been depicted with her impossible demands as that of the evil queen, or Stepmother.
The story brought to mind many characters of situations:
Beauty and BeastThe cuddle of eternal loveThe faith and nature of life are indeed visible in this story.Such as the above story, Psyche appears to believe that she'll be wanted to send to have been the bride of such a terrifying dragon who conceals from her after week as well. Very much like that novel, she was therefore persuaded by her sisters to deceive himself, who forced herself to inform on him. Cupid waking someone up from her deep sleep is like the conventional Touch of true soul mate administered by innumerable royalty to activate respective princesses. However, when Psyche has always been helped make immortal, the power of prayer overcomes everything so that the two main characters can indeed be formed forever.

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.

After surgical removal of the spleen (i.e., a splenectomy), some other organs take over most of its functions. Which of the following spleen functions in the adult can not be performed by bone marrow?
A) immune surveillance
B) erythropoiesis
C) removal of aged and damaged red blood cells from the blood
D) storage of platelets
Answer:
removal of aged and damaged red blood cells from the blood
Explanation:
Spleen is an organ found in vertebrates and it is located in the upper part of the abdomen that act majorly to filter blood. It recognizes and removes old, malformed, or damaged and aged red blood cells. When blood flows into the spleen, the spleen performs "quality control"; the red blood cells must pass through a maze of narrow passages.
The bone marrow is a spongy tissue that produced red blood cells and this perform similar function as the spleen except that it cannot remove aged and damaged red blood cells from the blood this is because it does not have the ability to remove age and damage red blood cells due to inability to support the immune system.
The spleen help remove age and damage red blood cells thereby boosting the immune system in fighting against infections ,preventing blood clot .

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.

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.

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.

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.

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.
