Mendel crossed homozygous tall and short plants. The law of segregation dictates that each sperm of the tall plant randomly pass

es
down one allele for height and the eggs of each short plant also pass down one allele for height to the F1 generation seed. Predict the F1
generation genotype.
O If the homozygous tall plant (TT) crosses with a heterozygous short plant (Tt), then all the F1 plants become heterozygous tall plants (Tt).
O If the heterozygous tall plant (TT) crosses with a heterozygous short plant (Tt), then all the F1 plants become heterozygous tall plants (Tt).
O If the heterozygous tall plant (Tt) crosses with a homozygous short plant (tt), then all the F1 plants become heterozygous tall plants (Tt).
O If the homozygous tall plant (TT) crosses with a homozygous short plant (tt), then all the F1 plants become heterozygous tall plants (Tt).

Answer:

D.) If the homozygous tall plant (TT) crosses with a homozygous short plant (tt), then all the F1 plants become heterozygous tall plants (Tt).

Explanation:

Homozygous indicates that the alleles in the genotype are the same. Therefore, the genotype for homozygous tall plants is (TT) and the genotype for homozygous short plants is (tt).

After performing a cross, we know that all of the children will have the heterozygous genotype (Tt).

When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!

4. Your classmate is viewing a sample
Serhud [2]
I would recommend to move the slide away from the end of the viewing part of the microscope, so that if the lab partner were to adjust too much, that the viewing part of the microscope wouldn’t collide and passively crack the slide.

What are possible negative effects of building a hydropower dam? Select the two correct answers.
MrMuchimi

The correct answers are B; Displacement of people living near the proposed dam and C; Lower river water levels in other areas.

Further Explanation:

The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.

When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.

In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.

1.6. Sierra is asked to demonstrate how carbon travels from the atmosphere to living organisms, then
stiks02 [169]

Answer:

<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>

Explanation:

The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.
