Unattached earlobes is a dominant trait, E. A parent who is homozygous for unattached earlobes is crossed with a parent who is
homozygous for attached earlobes. Which describes the genotypes of their offspring?
100 percent Ee
100 percent unattached earlobes
100 percent ee
100 percent attached earlobes

Answers

Answer 1

Answer:

100 percent Ee

Explanation:

This is a cross involving a single gene coding for attachment or not of earlobes. The allele for unattached earlobes (E) is dominant over the allele for attached earlobe (e). This means that allele E will always mask the phenotypic expression of e in a heterozygous state.

A parent that has same alleles for unattached earlobes i.e. EE is crossed with a parent that has same alleles for attached earlobes i.e. ee. In this cross, all of the offsprings will have a heterozygous genotype, Ee because gametes E and e will be produced respectively by each parent.

Hence, since all of the offsprings will have an Ee genotype, it means 100% of their offsprings will have Ee (HETEROZYGOUS).

Unattached Earlobes Is A Dominant Trait, E. A Parent Who Is Homozygous For Unattached Earlobes Is Crossed

Answers

tendons connect muscles to bones.

Answer : d
Explanation:
Lying outside the epitenon and contiguous with it is a loose elastic connective tissue layer known as paratenon, which allows the tendon to move against neighbouring tissues. The tendon is attached to the bone by collagenous fibres (Sharpey fibres) that continue into the matrix of the bone.

THIS IS DUE TOMORROW - Why is it important to reduce your ecological footprint? What services do ecosystems provide for us/future generations?

Answers

Answer:

The ecological footprint (EF) estimates the biologically productive land and sea area needed to provide the renewable resources that a population consumes and to absorb the wastes it generates—using prevailing technology and resource-management practices—rather than trying to determine how many people a given land area

Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provisioning, regulating, and cultural services that directly affect people, and supporting services needed to maintain the other services.

what is the composition of gastric juice and their functions?

Answers

Answer:

Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes

Explanation:

The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.

Answers:

It is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. It is found in all vertebrates.

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model

Answers

Answer: its C

Explanation:

Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.

A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.

In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.

Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.

Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.

Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.

In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

How does transferring energy into a container of magnetic marbles affect the speed by shaking the container gently?

Answers

By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.

What is kinetic energy?

All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

It is only possible to see the moon when it is reflecting sunlight.In this case, no other type of celestial body must be in front of the moon, blocking the sunlight.As we can see in the question above, sunlight is being emitted from left to right.Although the moon is in the right direction to reflect this light, the earth is in front of the moon.Therefore, sunlight will not shine on the moon, because the earth will block it and cast a shadow over the moon.

Therefore, it will not be possible to see the moon, as Felipe said.

It would be located on the picturesque banks of Grays Harbor and have its own championship-level golf course. The cost to purchase the land would be $1 million, payable now. Construction costs would be approximately $2 million, payable at the end of year 1. However, the construction costs are uncertain. These costs could be up to 20 percent higher or lower than the estimate of $2 million. Assume that the construction costs would follow a triangular distribution. ADC is very uncertain about the annual operating profits (or losses) that would be generated once the hotel is constructed. Its best estimate for the annual operating profit that would be generated in years 2, 3, 4, and 5 is $700,000. Due to the great uncertainty, the estimate of the standard deviation of the annual operating profit in each year also is $700,000. Assume that the yearly profits are statistically independent and follow the normal distribution. After year 5, ADC plans to sell the hotel. The selling price is likely to be somewhere between $4 and $8 million (assume a uniform distribution). ADC uses a 10 percent discount rate for calculating net present value.
