Answer:

The correct answer would be - the ratio of phenotypes in an organism cross will tell if the genes are linked or not.

Explanation:

In this question, we perform a test cross with a fruit fly that is heterozygous If we perform a test cross between two parents with identical heterozygous genomes AaBb.

If there is no recombination found in the offspring of this cross it means there are no linkage of genes present.  And if there are new or recombinant phenotypes present it means that there are genes linked together.

<span>The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history. In Precambrian rocks, however, fossils are rare; thus, the geologic record of this important part of the Earth’s history has been especially difficult to decipher. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.</span>

Take a hypothetical bowl and add some water and some cooking oil and let the mixture settle. As you know, the mixture will separ
bazaltina [42]

Answer:

Phospholipid is the molecules that are amphipathic in nature means the molecule has both hydrophobic as well as hydrophilic regions. The phospholipids are the important constituent of the plasma membrane.

The water and oil gets separate when mix together. If the phospholipid is mixed with the oil and water solution than the oil part is mixed with the hydrophobic part and water will mix with the hydrophilic parts. They can form micelles together.

Jon likes hiking. He observes that whenever he hikes up a hill he breathes heavier than when he is on flat ground. Which 2 state
Alekssandra [29.7K]

Answer:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

Explanation:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

-The body has too little carbon dioxide to maintain function.

-The body is using carbon dioxide instead of oxygen to make energy.

-Blood pressure has decreased, so less blood is being pumped to the muscles.

<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>

At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.

<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>
