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
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.
Answer:
inherited

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
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.

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

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

Describe where in nature you would see contaminated water actively weathering rocks and how it may differ from non-contaminated water.
Answer:
The contaminated water contains harmful chemicals which results in the cracking of rock.
For example: The feldspar crystals within the granite react with the water chemically to form clay minerals which makes the rock weak and hence result in weathering.

Answer:
I am pretty sure it is, The consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton. But I am not positive, I hope this helps!!
Explanation:
Option C, It consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton.
The part of the vertebrate skeleton that has the bones that hold up the body is the appendicular skeleton, which comprises the elements within the limbs, pelvic and pectoral girdle. It holds the bones that produce and uphold the libms and joins them with the axial skeleton. The appendicular skeleton has 126 bones and helps manipulate the upper limbs.
What two basic geologic processes contributed to the formation of folded mountain ranges like in Glacier National Park?
A. Folding and breaking of ingenuous rocks and tectonic uplifting.
B. Faulting of sedimentary rock and erosion.
C. Volcanic ash buildup and faulting of rocks.
D. Folding and breaking of sedimentary rocks and erosion.
Answer:
D. Folding and breaking of sedimentary rocks and erosion.
The two basic geologic processes that contributes to the formation of folded mountain ranges are ; ( D ) Folding and breaking of sedimentary rocks and erosion
Folded mountains are formed by the collision of two or tectonic plates, the movement and collision is mostly caused by massive erosion.
Tectonic plates are formed by the breaking down of the earth's outermost layer into large rock slabs which lies on a molten layer of rock these large slabs are components/make up the sedimentary rocks
Therefore the folding and breaking of sedimentary rocks caused by massive erosion leads to the formation of folded mountain ranges.
Hence we can conclude that The two basic geologic processes that contributes to the formation of folded mountain ranges are ; Folding and breaking of sedimentary rocks and erosion

More than 90% of plants have mycorrhizal associations with fungi. How might this association have evolved (include mechanisms)
Answer:
It is a symbiotic relationship and it evolved because of the benefits both plants and fungi derive from the association.
Explanation:
Mycorrhizal association is a symbiotic association between fungi and plants where both of the benefits from the relationship. The fungi inhabit the root system of plants which increase the ability of the plant's root system to absorb water for it own use and the fungi benefited from it by carbohydrates from plants which is produced as a result of photosynthesis.
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
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 .
