Complete dominance occurs when the dominant allele completely masks the recessive allele in heter0zyg0us individuals. 1) 100% / 2) no chance / 3) 50% / 4) no chance / 5) 1:2:1.
------------------------------------------------------------
Available data:
→ Six diallelic genes code for six different traits.
→ All genes express complete dominance, meaning that the dominant allele hides the expression of the recessive one.
→ Beyonce ⇒ ee ww Dd Hh cc Bb
→ Bruno Mars ⇒ ee ww dd Hh CC Bb
→ Cross: Beyonce x Bruno Mars

There is no chance for their children to have widow’s peak because both of them are h0m0zyg0us recessive for the trait.

4) Chin
Parentals) CC x cc
Gametes) C C c c
Punnett square) C C
c Cc Cc
c Cc Cc
F1) 100% of the progeny is expected to have cleft chin, Cc
There is no chance for their children to have smooth chin because one of them is h0m0zyg0us dominant and the other one is h0m0zyg0us recessive for the trait. C hides the expression of c.
The whole porgeny is expected to be heter0zyg0us, Cc, expressing cleft chin.

F1) 3/4 = 75% of the progeny is expected to have brown eyes, BB + Bb
1/4 = 25% of the progeny is expected to have blue eyes, bb
Genotypic ratio ⇒ 1:2:1 Phenotypic ratio ⇒ 3:1

In a signal transduction pathway, fine tuning of the cellular response occurs in several steps. Which of the following best describes how the response would be affected if the molecular changes that occur during a signaling pathway lasted for a prolonged period?
Inactivation mechanisms would be triggered before the pathway could be completed.
Receptors would be unable to return to their inactive form and respond to new signals.
Scaffolding proteins would cause potentially harmful signal amplification in the cytosol.
Signaling proteins would be unable to take part in multiple pathways, as specificity is lost.
Answers
Answer: Receptors would be unable to return to their inactive form and respond to new signals.
Explanation:
Many signaling pathway involves the regulation of the protein synthesis. It involves the turning off or on of some of the specific genes present in the nucleus. If the receptors become unable to resume to the inactive form the may not be able to produce new signals during protein synthesis. The final activated molecule in a signal pathway may not function as transcription factor.
Answer:
Receptors would be unable to return to their inactive form and respond to new signals.

What are the four major categories of Marco molecules? Describe the basic structures and primary functions of each
Answers
Answer:
Explanation:
question 1:
Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules. these are carbohydrates, lipids, proteins, and nucleic acids. Each is an important cell component and performs a wide array of functions.
question 2:
Carbohydrates
Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.
Lipids
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon–carbon or carbon–hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals.
Proteins
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. mail me via at 16jacktwinwritters for more explanation and further clarification. Each cell in a living system may contain thousands of proteins, each with a unique function. Their structures, like their functions, vary greatly.
Nucleic Acids
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

Long Bones.
Explanation:
Hope this helped :).
The femur, tibia, humerus, and radius are all classified as Long bones.
Thus, Long bones are tough, dense bones that offer stability, movement, and strength. The femur, or thigh bone, is a long bone. A long bone has two ends and a shaft.
Despite their small lengths, some of the fingers' bones are categorized as long bones. Not the size of the bones, but their shape is to blame for this. Red and yellow bone marrow, which are found in long bones, are responsible for producing blood cells.

Provitamin A, also known as beta-carotene, is necessary for human health. People who do not make this substance suffer serious medical problems. Which application of genetic technology has been the MOST promising for treating people who suffer from a deficiency of provitamin A?
Answers
Answer:
The application of genetic engineering called golden rice
Explanation:
Golden Rice is a genetically engineered biofortified crop designed by biosynthesizing beta carotene in the edible part of rice. Golden rice was created by transforming rice with two beta-carotene biosynthesis genes: psy (phytoene synthase) from daffodil ('Narcissus pseudonarcissus') crtI (phytoene desaturase) from the soil bacterium Erwinia uredovora.
Golden rice was genetically modified to provide beta-carotene, which is converted into vitamin A in the body, which is an essential nutrient that white rice lacks.

Explanation:
The uplifting of water occurs due to earthquake in the sea floor is refers to potential energy while on the other hand, the movement of water to the land in the form of waves is the kinetic energy. So we can see that the transformations of energy occurs from potential energy due to earthquake into kinetic energy occurs due to movement of water in the form of giant waves (tsunami).

Some entomologists believe that the evolutionary reason that plants expend energy to produce fall color is to warn pests. A plant that is healthy is able to produce lots of carbohydrates, and therefore more anthocyanins. Some insect pests will not lay eggs on bright colored leaves. Instead, they will find a “weaker” drab/dull colored tree on which to lay eggs. Some scientists believe that anthocyanins may act as a sunscreen to inhibit the destruction of the chlorophyll, help to prevent frost injury to leaf tissues, or limit water loss during dry spells in autumn. As far as the fall foliage watcher is concerned, their purpose is simple—they signal a last hurrah for the growing season and delight the optic nerve.

Answer:
How do trees turn color?
In the fall, trees break down the green pigments and nutrients stored in their leaves. The nutrients are shuttled into the tree's roots for reuse in the spring. It's then that the trees take on their autumn hues. As leaves lose their chlorophyll, other pigments become visible to the human eye, according to Bryan A.
