Answer:
50%, and 0%
Explanation:
Make a chart, and fill it in
a)
_ |E | e
e |Ee | ee
e |Ee | ee
2/4 have Ee, and 2/4 have ee, ee is the attached, so the chance is 2/4, or 50%
b)
hom*zygous means that both letters are the same, so EE, or ee
the mother is EE, while the father is ee
make a table:
_ |E | E
e |Ee | Ee
e |Ee | Ee
As you can see, it's all Ee, so the only possibility is for the child to have detached earlobes, and no attached earlobes are produced (in theory, at least)

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.

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.

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.

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.

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.

The important biochemical process that receives a supply of NAD+ ions from the fermentation process during anaerobic respiration is glycolysis. Hence option C is correct.
What is Glycolysis?Glycolysis is the first step in both aerobic and anaerobic respiration. It takes place in the cytoplasm and involves the breakdown of glucose into pyruvate. During the process, NAD+ ions are reduced to NADH, which is an energy-rich molecule that is used in the electron transport chain to produce ATP.
In anaerobic respiration, when oxygen is not available, the electron transport chain cannot function, and the cell must rely on other processes to regenerate NAD+.
Fermentation is one such process, and it involves the reduction of pyruvate to other organic molecules, such as lactic acid or ethanol. This process regenerates NAD+ from NADH, which can then be used in glycolysis to produce more ATP.
Therefore, during anaerobic respiration, the fermentation process supplies NAD+ ions to glycolysis, allowing the cell to continue producing ATP in the absence of oxygen.
Hence option C glycolysis is correct.
