During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
What is a tetrad?A tetrad is a structure formed during the prophase I stage of meiosis I whereby two homologous chromosomes pair together.
Meiosis occurs in two stages of division namely;
meiosis I meiosis IIIn meiosis I, homologous chromosomes are separated but are first paired during the prophase stage to form the tetrad or bivalent structure.
Therefore, during prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.

What happens to the rate of diffusion if the temperature is raised?
Answer:
The rate of diffusion increases
Explanation:
This is because increase in temperature causes increase in the average speed of molecules which increases the rate of diffusion
Answer:
The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

During which phase of meiosis do the homologous chromosomes line up across from each other in the center of the cell?
Answer: In metaphase I, homologous chromosomes line up along the center of the cell in order to be pulled apart.
Explanation:
Meiosis is the type of cell division in the germinal cells. In metaphase I of meiosis, the homologous chromosomes line up across from each other in the center of the cell.
What is metaphase I?Metaphase I is one of the stages of meiosis I in which the duplicated homologous chromosome pairs align at the center of the cell along the midline and are connected through the centrioles.
In prophase I the homologous chromosomes are created and in anaphase I, the aligned chromosomes move towards the opposite poles so that after division each cell has the same number and equal composition of chromosomes.
Therefore, in metaphase I the homologous chromosomes are aligned at the midline.

The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.
The pulmonary circulationThe circulatory system is divided into two main parts namely:
pulmonary circulation and systemic circulation.The pulmonary circulation involves the movement of blood between the lungs and the heart.
Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.
After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.
The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.
Which question most closely relates to the biologist's observations and collected data?
Are the golden frogs succumbing to a fungal infection?
Did the golden frogs migrate to a new habitat?
Why was a copper mine built so close to the stream?
Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?
Answer:
The most likely answer would be D, Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?
Explanation:
The golden frogs live either close to the stream or in it, which means the acidity and toxicity could kill them.

A student is asked to draw a food web in which the same organism is a primary consumer as well as a secondary consumer. How should the organism be represented in the food web?.
Answer:
The primary producers (grass, flowers, weeds) should be at the bottom because they are then eaten by primary consumers (rabbits, mice, squirrels). The secondary consumers would be on top (owls, eagles, hawks) because they eat the primary consumers.

Can someone please help me? :(
Answer:
B
Explanation:
only option that reduces the use of motorized vehicles
Answer:
B. Building new bike paths in the city.
Explanation:
This is the most possible way since...
If there are more bike paths, then there are more ways that they are going, which means more usage of them. If there is going to be more usage of them, then there is going to be less usage of cars in the city.So hence, your answer is B. Building new bike paths in the city.
Now, let's look WHY are the other ones NOT the right answer:
A. Widening roads throughout the city
This just won't do anything, rather, it will make drivers more want to go on the road since the roads are wider and easier to drive on.
B. Buliding new bike paths in the city
this is the right answer, for explanation, look above
C. Expanding the city into nearby areas
There is no use of the city being expanded, that way, if you live in one corner of the city, and your office is in the other side, then you wouldn't want to use your bike, you'll want to use the car, which is what you don't want to do.
D. Raising the price of riding the city bus
Not helpful either, this won't help that much, since 1 job will lose, 2nd, people who don't know how to drive or are pregant(probably can't ride a bike) won't be able to travel. And last, it's just so selfish..
So from all these conclusions, we can see that B is truly the answer.Buliding new bike paths in the city.-------------------------------------------------------------------------------------------------------"The beautiful thing about learning is that no one can take it away from you!" B.B.King

Your body needs a constant supply of oxygen for cellular respiration to produce the ATP needed to fuel your body processes. When you exert yourself in a strenuous workout the oxygen demands of your muscle cells quickly outpace the oxygen your body can provide. Skeletal muscle cells that have an insufficient oxygen supply to allow aerobic respiration to continue will undergo lactic acid fermentation. Refer to the model above. Predict what changes will occur when your body shifts from aerobic respiration to anaerobic respiration (lactic acid fermentation). Select ALL that apply.

how is the level of thyroxine controlled gsce
Explanation:
Its levels are controlled by negative feedback. The hypothalamus and pituitary gland have important roles in detecting and controlling thyroxine levels. Low thyroxine levels in the bloodstream stimulate the hypothalamus to release TRH and this causes the pituitary to release TSH so the thyroid releases more thyroxine.
