Answer:
Offspring acquire a mix of traits from their biological parents. Different organisms vary in how they look and function because they have different inherited information. In each kind of organism there is variation in the traits themselves, and different kinds of organisms may have different versions of the trait.
You want to determine whether short wings in fruit flies are the result of a dominant or recessive mutation. You cross a short-winged fly stock with a long-winged fly stock (which is considered to be wild type or / ). The progeny have a 1:1 ratio of short to long wings. You then allow the F1 short-winged flies to mate. The F2 progeny have a phenotypic ratio of 3:1 short to long wings. Short wings are likely the result of:
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

The pectoral girdle includes the_____
and the_____.
1)
-ischia
-sacrum
-clavicles
-ilium
2)
-ilium
-ischia
-sacrum
-clavicles
Answer: Clavicle and Scapula
Explanation:
The pectoral girdle also known as the shoulder girdle forms part of the appendicular skeleton also known as the upper limbs.
It is located at the upper part of the body, connecting each arm to the body.
It consists of the scapula (found on either side of the body) also known as the shoulder blade that joins the collar bone to the humerus.
It also consists of the clavicle ( the only one bone in the body that lies horizontally) located on either side of the body which serves as a system of support for the breastbone and the shoulder blade
What is the main difference between the intertidal zone and the neritic zone?
the amount of exposure to sunlight
the amount of salt in the water
the amount of time covered by water
the presence of plants and animals
Answer:
intertidal zone is the area of shore between the high tide and low tide lines whereas neritic zone is the area of the ocean from the low tide line out to the continental shelf.
The main difference between the intertidal zone and the neritic zone is the amount of time covered by water.
What is intertidal zone and the neritic zone?The intertidal zone is the area of the shoreline that is regularly exposed to air at low tide and submerged at high tide. This area is characterized by its exposure to fluctuations in water level, temperature, and salinity, and is home to a diverse range of organisms that have adapted to these conditions.
The neritic zone, on the other hand, is the shallow ocean water over the continental shelf, extending from the low tide mark to a depth of about 200 meters. Unlike the intertidal zone, the neritic zone is always covered by water and is characterized by relatively stable physical conditions, including a relatively constant temperature and salinity.
While the amount of exposure to sunlight can vary in both the intertidal and neritic zones, the main difference between these two habitats is the amount of time covered by water and the resulting stability of environmental conditions.

Which type of cell has a nucleus?
Prokaryotic Cell
Or
Eukaryotic Cell
Answer:
Eukaryotic cell
Explanation:
The cell of living organisms have been classified as either eukaryotic or prokaryotic depending on whether or not it contains a NUCLEUS. A prokaryotic cell is a cell that does not contain a membrane-bound nucleus to house its genetic material e.g bacteria, archaebacteria etc.
On the contrary, eukaryotic cells possess a membrane-bound nucleus that houses their genetic material e.g fungi, animals, plants etc. Based on the above explanation, an EUKARYOTIC type of cell produces a nucleus.

Under which condition below would you expect a coarse- grained intrusive rock like diorite to form?
Answer:
Diorite is a course-grained igneous rock that forms when magma rich in silica cools slowly deep within the Earth's crust.
Or Slow cooling in the upper mantle.
Explanation:
Upper mantle is the condition below would you expect a coarse- grained.
What is Upper mantle?The Earth's upper mantle is a very thick layer of rock that extends from just below the crust (at a depth of 10 km (6.2 mi) beneath the oceans and 35 km (22 mi) beneath the continents) to the top of the lower mantle at a depth of 670 km (420 mi).
At the top boundary with the crust, temperatures range from roughly 500 K (227 °C; 440 °F) to roughly 1,200 K (930 °C; 1,700 °F) at the lower mantle border.
Depending on depth, the upper mantle material that has reached the surface is made up of roughly 55% olivine, 35% pyroxene, and 5–10% calcium oxide and aluminum oxide minerals like plagioclase, spinel, or garnet.
Therefore, Upper mantle is the condition below would you expect a coarse- grained.
