HELP PLEASE In the following cross, assume simple dominance and independent assortment for each trait. What proportion of the progeny will be expected to phenotypically resemble the second parent?
AABB x Aabb
1. 1/4
2. 1/8
3. 3/4
4. 3/8
Answer:
0
Explanation:
This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:
AABB- AB, AB, AB, AB
Aabb - Ab, Ab, ab, ab
Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:
AABb = 4/16 = 1/4
AaBb = 4/16 = 1/4
Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).

What are the three forces that drive (create and cause to continue) ocean currents?
Answer:
The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. ...
Wind. Winds drive currents that are at or near the ocean's surface. ...
Thermohaline circulation.
Explanation:
The three forces that drive (create and cause continuing) ocean currents are wind, water density differences, and tides.
What are ocean currents?Gravity, wind, and water density all contribute to the continuous, predictable, directed movement of seawater known as ocean currents. Water in the ocean can move both horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or dwellings.
The three main water flows in oceans are waves, tides, and ocean currents. Waves are produced by the wind's effect on the ocean's surface. The temperature difference between the warmer equator and the cooler poles causes ocean currents.
Therefore, the three factors of wind, water density variations, and tides are what drive (make, generate, and sustain) ocean currents.

How did the Cuyahoga RIver in 1969 impact the future of our environment?
Answer:
Answer:The 1969 Cuyahoga River fire catalyzed water pollution control activities, resulting in the creation of the federal Environmental Protection Agency (1970) and the Ohio Environmental Protection Agency (OEPA), and passage of the Clean Water Act (1972) and the Great Lakes Water The Cuyahoga River has caught fire a total of 13 times dating back to 1868. But the fire in 1969, helped spur action that ultimately led to the passage of the Clean Water Act in 1972. Later that year, Congress passed the National Environmental Policy Act.Quality Agreement (1972).

According to the rock cycle, how can sedimentary rock be transformed into metamorphic rock?
A)
by melting the sedimentary rock
B)
weathering and erosion of the sedimentary rock

by the process of uplifting the sedimentary rock
D)
exposing the sedimentary rock to extreme temperature and pressure
Ok
Answer:
D
Explanation:
Those sediments can be formed from the weathering and erosion of preexisting rocks. Sedimentary rocks also include chemical precipitates, the solid materials left behind after a liquid evaporates. Metamorphic rocks form when the minerals in an existing rock are changed by heat or pressure below the surface.

5. Peppered moths vary in darkness. Some have a lighter
coloration and some have a darker coloration. Before the
industrial revolution only 2% of the moth population was
darker in coloration. After the industrial revolution, 95% of
the population showed this darker coloration. Birds eat the
moths they can see on the trees.

Why are viruses labeled as parasites/pathogens
Answer:
Parasites are part of a large group of organisms called eukaryotes. Parasites are different from bacteria or viruses because their cells share many features with human cells including a defined nucleus. Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.
Explanation:

During the propagation of the excitation wave along the sarcolemma, the action potentials travel down the _________, stimulating the intracellular release of calcium ions.
Answer:
T-tubules (transverse tubules)
Explanation:
T-tubules, also known as transverse tubules, are narrow tubes that are continuous with the sarcolemma (i.e., the cell membrane of striated muscle cells). In skeletal/cardiac muscle cells, T-tubules form invaginations of the sarcolemma that contain many ion channels involved in excitation-contraction (e-c) coupling of muscle cells. Thus, transverse tubules function to conduct the action potential from the cell membrane (sarcolemma) to the interior of the muscle cell.
