NOT MY ANSWERS! COPIED FROM palmchika13!!

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

F1) 100% of the progeny is expected to have straight hairline, ww.

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

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.

      1/4 = 25% of the progeny is expected to have blue eyes, bb

Answer:

Systemic circulation is the movement of blood between the heart and the rest of the body.

Explanation:

The oxygenated blood will pass through the left ventricle to arteries then the capillaries of the body. After the oxygenated blood is distributed to all parts of the body, the now deoxygenated blood will return through a network of veins thus, to the right atrium of the heart.

Parents pass their traits down to their offspring through their genetic material in gametes. Details about genetic material can be found below.

Biological traits are passed from parents to their offsprings during reproduction.

These traits are encoded by the genes contained in living organisms. These genes are present in the genetic material of the organism.

This means that parents pass their traits down to their offspring through their genetic material in gametes.

Answer:

Explanation:

1. Since brown is dominant to black, in order for the farmer to determine the genotype of the brown bull, he will need to test-cross the bull with a black bull. The phenotypes of the offspring from the testcross will determine whether the brown bull is a true-breeding one or a heterozygous one.

If all the offspring from the testcross are brown, it means the bull is a true-breeding brown. If the offspring is a mix of brown and black, it means the bull is heterozygous for the brown genotype.

To further illustrate the explanation, let us assume that the brown allele is B and the black allele is b. B is dominant over b, hence, a brown bull can BB or Bb while a black bull can only be bb.

The rancher is not sure if the bull he bought is BB or Bb, hence, he needs to testcross with another bull that is bb. Assuming that the rancher's bull is BB

           BB     x     bb

       Bb    Bb    Bb    Bb (all brown)

Assuming the rancher's bull is Bb

            Bb     x     bb

        Bb    Bb    bb    bb (50% brown, 50% black)

2. All the information that the rancher needs have been explained above. No other information is needed

Answer:

Shared characteristics are features or qualities that organisms or species have in common.

Shared characteristics can be characteristics that existed in the common ancestor and still exist in modern organisms.

Shared characteristics can be new characteristics that have been modified from what was found in the common ancestor.

Answer:

The use of enzymes or microorganisms in food preparations is an age-old process. With the advancement of technology, novel enzymes with wide range of applications and specificity have been developed and new application areas are still being explored. Microorganisms such as bacteria, yeast and fungi and their enzymes are widely used in several food preparations for improving the taste and texture and they offer huge economic benefits to industries. Microbial enzymes are the preferred source to plants or animals due to several advantages such as easy, cost-effective and consistent production. The present review discusses the recent advancement in enzyme technology for food industries. A comprehensive list of enzymes used in food processing, the microbial source of these enzymes and the wide range of their application are discussed.

Thrust helps to move the rocket against gravity.

Explanation:

The amount of a rocket's thrust affect its trajectory because this thrust help the rocket to move against the gravity of the earth. More force in the form of thrust is needed by orbiting spacecraft to escape its orbit because the orbit does not allow the orbiting spacecraft to escape so for that force is needed to to against its orbit. First, we need to escape from the gravity of earth then go towards the mars. after entering the gravity of mass, we used a force which helps in safe landing on the mars.

Explanation:

Answer:

its 30 N

since it didn't change it stays the same 30N.

Since the forces are in opposite direction to each, the net force of the two players is equal to zero Newton.

If two players push against each other with 30 N of force, That is, player 1 exert 30 N of force on player 2 while player 2 also exert 30 N of force on player 1 and no yardage is gained or lost.

Force is a vector quantity, that is, we will consider both the magnitude and direction. The resultant or net force of the two players can be expressed as:

Net Force = Player 1 force - Player 2 force

Net force = 30 - 30

Net force = 0

Since the forces are in opposite direction to each others and they are also of the same magnitude without any gain or loss of energy, the two forces will counterbalance each other.

Therefore, the net force of the two players is equal to zero Newton.

It can only be produced in sunny areas.

Answer:

It can only be produced in sunny areas

Explanation:

when an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism , reproduction occurs by fragmentation.

Photosynthesis allows plants, algae and certain bacteria to turn sunlight into chemical energy. The amazing feat is achieved because sunlight can fuel a reaction between water and carbon dioxide that, in turn, produces carbohydrates (simple sugars) and oxygen.

Answer:

The answer is below

Explanation:

1. Path A (Atmosphere) :

Carbon Path: Atmospheric CO2: this arises from geological sources such as volcanoes, burning fossil fuels, etc. This gets carbon dioxide back into the atmosphere during these processes.

2. Path G (Geosphere)

Carbon Path: Lithosphere: Earth’s carbon has been researched to have large limestone deposits. This limestone can be found in the Earth's lithosphere. Through the heating of limestone, carbon dioxide gets back to the atmosphere.

3. Path H (Hydrosphere)

Carbon Path: Oceania CO2: there is a large deposit of dissolved CO2 underneath the ocean. As the ocean gets colder, it dissolves more. The plants absorbed carbon dioxide through photosynthesis and get back to the atmosphere

The earth's atmosphere has layers: the exosphere, thermosphere, mesosphere, stratosphere, and troposphere from highest to lowest levels.

These layers are composed of Nitrogen, oxygen, other gases and are defined by unique characteristics of temperature and pressure.

1. Path A (Atmosphere)

The carbon path in this layer involves atmospheric carbon dioxide. The burning of fossil fuels like petrol, coal, diesel, volcanic explosions and wildfires brings back the carbon dioxide in the atmosphere during these processes.

2. Path G (Geosphere)

The carbon path involves the lithosphere. Expiration by plant and animal, burning of carbonate rocks like limestone, shale gas and coal release carbon which get backs in the atmosphere.

3. Path H (Hydrosphere)

The carbon path involves oceanic carbon dioxide. Ocean and water bodies have enormous amounts of dissolved carbon in them. Aquatic plants use this diffused carbon dioxide and free it back into the atmosphere.

Sorry, I don't know the answer, but I do know this:

Explanation:

Cold-blooded animals have resistance against microorganisms, and when they are infected, they reduce body temperature as a defense mechanism. Warm-blooded animals have a much stronger immune system to defend against such microorganisms. They gain energy in the form of heat to regulate body temperature for survival.
