If free ear lobes ( L ) are dominant over attached ear lobes ( l ) what is the phenotype of an individual with a genotype of l l ?
a. attached ear lobes
b. Free ear lobes
c. L L
d. One ear lobe attached, one ear lobe free
Answer:
An individual with an ll genotype (recessive) for the ear lobe shape trait will have a phenotype of attached ear lobes (option a).
Explanation:
The phenotypic expression of a recessive trait only occurs when both members of the allelic pair are recessive, while the presence of at least one dominant allele inhibits the expression of the recessive trait.
In this case, for the "ear lobe shape" trait, an individual with a genotype ll has a phenotype of attached ear lobes, which is recessive. In contrast, LL and Ll genotypes would express a free ear lobes phenotype.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
What is the process by which food produced in
photosynthesis is transported from the leaves to
the growing regions of plants and storage
organs?
Answer:
Translocation
Explanation:
Biosynthesis of carbohydrates in green plants is called photosynthesis. This proces uses inorganic carbon (CO2), water and solar energy in a complex, multi-step process in mesophyll cells of leaves (sources).
Afterward, plants optimize the reaction products for use or storage in other regions. Plants form sucrose, as an energy-efficient storage molecule for transportation and later storage.
Sucrose contains more energy than the monomer, glucoseSucrose is a highly stable non-reducing sugar- it is non-reactive.These sugars move through the mesophyll via plasmodesmata; here, they reach phloem sieve tube elements in vascular bundles. From the STEs, they are actively transported against their concentration gradient to the phloem.
When the sugars enter the phloem, their high concentration cause water to move into the phloem from neighboring xylem vessel. This increases the water pressure inside the phloem, causing the sap to move towards sinks. Sinks may be actively growing regions or storage like the roots. There, the sucrose is polymerized into starch for long term storage.

Since oxygen gas is being released, it can be inferred
that the plant is
A. producing glucose
B. releasing energy from water
C. making protein
D. carrying on active transport
Answer:
Option A
Explanation:
The answer is option A or "producing glucose." Glucose is a sugar that is a main component for all living organisms because it contains carbohydrates. When oxygen is being released from a plant it means that it's producing glucose which is released through the plants stomata.
Hope this helps.
Since oxygen gas is being released it can be inferred that the plant is PRODUCING GLUCOSE. (Option A).
Photosynthesis is a series of metabolic reactions by which plants and algae use the energy from the sun and carbon dioxide to produce simple carbohydrates (e.g., glucose) and oxygen.
Photosynthesis has two main types of reactions: light-dependent reactions and light-independent reactions (i.e., the Calvin cycle).
During light-independent reactions, carbon-containing molecules such as, for example, glucose molecules, are produced from carbon dioxide.
In conclusion, when oxygen gas is being released it can be inferred that the plant is PRODUCING GLUCOSE (Option A).

C. not moving
D. speeding up
Answer:
1) D
2) C
3) B
Explanation:
1) The position and time increase, speeding up
2) The position and time do not change, therefore it is not moving
3) The position and time are moving, but at a constant speed.
Object's motion with the position-time graph that represents at:

2) C
3) B
What do you mean by motion of an object?Motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed.
Moreover, the free movement of a body with respect to time is known as motion. For example-the fan, the dust falling from the carpet, the water that flows from the tap, a ball rolling around, a moving car etc. Even the universe is in continual motion.
Therefore, it is a change of position or orientation of a body with the change of time. Motion along a line or a curve is named translation. Also, the motion that changes the orientation of a body is rotation.

How does static electricity work?
Answer:
"Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. ... Remember, objects with the same charge repel each other." ~ www.loc.gov
Essentially saying that if you have a lot of friction, it will create a positive and negative electric charge, this electric charge also contains a small magnetic field which is static electricity.

The following four ears of corn were taken from separate plants. Each kernel represents an offspring. The kernels on the four ears were counted for the color trait (purple or white) and/or sweetness trait (starchy or sweet). The data gave these phenotypic ratios for the four ears:
Ear #1 – 3 purple : 1 white
Ear #2 – 3 starchy : 1 sweet
Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Ear #4 – 1 purple : 1 white
Which traits are recessive?
Answer:
the answer is white and sweet, i just took the quiz
Explanation:
The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.
-------------------------------
By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.
Let us assume two diallelic genes, each coding for one trait.
Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.
When we are only considering one single gene,
the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1
9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.
Now let us analyze each Ear,
Ear #1 – 3 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white
Ear #2 – 3 starchy : 1 sweet
Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweetEar #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweetEar #4 – 1 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: WhiteThe recessive traits are white color and sweet taste.
