Discuss how constraints related to biology and management affect the choice of a crossbreeding system. Please be descriptive.

Answers

Answer:

Some important constraints:  

-Plant breeding: autogamy and allogamy, self-sterility, etc  

-Animal breeding:  trait compatibility

- Breeding systems in general (i.e., both in plants and animals): barriers for sexual reproduction  

Explanation:

Crossbreeding systems consist of the breeding between two breeds in order to develop progeny with particular advantageous phenotypic traits. In-plant crossbreeding systems, it is imperative to have into account whether the plant is autogamous (reproducing by self-pollination) or allogamous (reproducing by cross-fertilization), because it will affect the fitness of the progeny resulting from these breeds. Moreover, the biological mechanisms of self sterility and compatibility must be also taken into consideration. In-animal breeding systems, it is important to have into consideration that phenotypic traits we desire to obtain in the progeny must be compatible between races. In addition, the barriers for sexual reproduction are also an important issue both in plant and animal breeding systems, it thus being impossible, for example, to get a breeding between Chihuahua and Great Dane dogs.

Maltase is an enzyme that catalyzes the hydrolysis of the disaccharide maltose. This process occurs during human digestion when maltase is secreted by the intestine and then converts maltose into glucose. Which two classes of biomolecules are directly involved in this process?

A .proteins and carbohydrates

B. lipids and proteins

C. carbohydrates and nucleic acids

D. carbohydrates and lipids

Answers

Answer: D

Explanation:

Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.

What is Maltase?

Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.

Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.

Therefore, the correct option is D.

Jaden's father is not sensitive to poison ivy. Jaden is also not sensitive to poison ivy. Jaden's lack of sensitivity to
poison ivy is which kind of trait?
environmental
acquired
learned
inherited

Answers

Answer:

Jaden's lack of sensitivity to poison ivy may be an inherited trait.

Explanation:

The poison ivy poisoning is due to the essential oils of this plant, mainly uroshiol, causing a reaction in the skin characterized by intense itching, redness and even burns with flicthenes, manifesting as an allergic reaction of varying severity.

Some people may have a low sensitivity or be insensitive to uroshiol, which does not rule out the possibility that they may become sensitive at some point in their lives.

The fact that Jaden and her father are insensitive to poison ivy venom may be an inherited trait, determined by a resistance to the allergic reaction the plant produces.

Regarding other options:

    Environmental, acquired or learned traits, do not determine the resistance to certain hypersensitivity or allergy reactions, which depends on each person's immune response or sensitivity.

inherited

Which two phrases describe a situation that will cause a stationary object to start moving?

A. a net force greater than 0
B. unbalanced forces
C. a net force equal to 0
D. balanced forces​

Answers

Answer:

A .a net force greater than zero

B. Unbalanced Force

Explanation:

A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .

B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .

Which pair of factors affects the force of gravity between objects? direction and distance mass and distance mass and shape shape and time

Answers

Answer:

It's B

Explanation:

Mass and distance affects the force of gravity between objects.

Thus, option B is correct.

What is force of gravity?

Force of gravity is defined as the force of attraction between any two objects in the universe.

The force of attraction depends upon the mass of the object and the square of the distance between them.

Mass is the total amount of matter contained by an object.More the matter of the object has, the more the mass.Weight of an object can be zero but mass of the object cannot be zero.

Distance is defined as the amount of space between two places or things. Measurement of distance are kilometer, inch, foot, yard.

Therefore,Mass and distance affects the force of gravity between objects.

Thus, option B is correct.
