In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies.

The Galapagos pink land iguana, Conolophus marthae (C. marthaes, is native to
only one of the Galapagos Islands. its entire range is currently limited to Wolf
Volcano on Isabella Island. The iguana was first discovered this island in 1986
Genetic studies of the animal began sometime later, and it was identified as a
species separate from other guana populations on the Galapagos in 2009. Its
population might have been as high as 100 in 1986, but now there might be as few
as 10 of the animals left alive
Other evidence indicates at this species could have diverged from another line
of iguanas about 5.7 million years ago. After that the other line of iguanas diverged
into two other species. Cpallidus and C subcristatus

Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD.
a. True
b. False
Answer:
As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Many times, a person will fracture a bone before they even know they have bone loss.

Living organisms are classified in different ways. Cells can help determine an organism's classification. Describe how an organism with plant cells might be classified differently than an organism with animal cells.
Explanation:
A plant cell consists of one large vacuole that maintains the shape of the cell and stores nutrients. Animal cells, on the other hand, have multiple smaller vacuoles. Both plant and animal cells have a cell membrane, but only the former has a cell wall.

Describe the force of Earth’s gravity.
Answer
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

Why does the mass of a substance remain the same after a chemical reaction
Answer:
Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.
The chemical properties of an element
are determined by its
A- atomic mass
B-proton number
C-electron arrangement
D- atomic size
Answer:
C. electron arrangment
Explanation:
Electrons are the subatomic particles that influence an element's reactivity since they are exchanged during reactions.
Describe passive and active freezing protections that could be set in place for an orchard of apples being grown in New York State and explain why they might be effective.
3 SENTENCES AT THE LEAST
Answer:
A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.
Explanation:
this is the example answer. do what you will w it
The passive and active freezing protections can be done by planting facing north hill and providing overhead irrigation respectively.
What is Protection?This is the process of guarding something against damage from an external force.
The passive and active freezing protections are effective as it minimizes the risk of freezes and frosts during spring blooms.
