Fossils are typically recovered within Sedimentary Rock exposures. This is because Sedimentary rock is the rock found closest to that of Earth, and is practically exposed 24/7 to all of Earth's natural disasters and what-not.

A summer squash plant that produces disc‑shaped fruit is crossed with a summer squash plant that produces long fruit. All of the
ivanzaharov [21]

Explanation:

In the given question,

suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.

The genotype for white, disc shape fruits is- AABB

the genotype for yellow, long fruits is- aabb

F1 progeny will be- AABB x aabb

                                 AaBb

F2 cross-    AaBb    x    AaBb

                      AB          Ab          aB           ab

      AB        <em>AABB       AABb    AaBB       AaBb</em>

      Ab       <em>AABb       AAbb     AaBb       Aabb</em>

      aB      <em>  AaBB      AaBb      aaBB       aaBb</em>

      ab        <em>AaBb       Aabb      aaBb      aabb</em>

          The genotype of F2 cross are-

1.  9/16 A- B- disc-shaped (like F1)

2. 3/16 A- bb spherical

3. 3/16 aa B- spherical

4. 1/16 aa bb long.

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

What does active transport in cells need that passive transport does not?
hichkok12 [17]

Answer:

Passive Transport - Taking the Easy Road

While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules. It could be as simple as molecules moving freely such as osmosis or diffusion.

During a lunar eclipse, what blocks the light from hitting the moon's surface?
Allushta [10]

Answer:

Lunar Eclipse: The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. (This sunlight is what causes the moon to shine.)
