dominant genes mask recessive genes are represented by lower xase letters are only inherited from the male parent are masked by recesive genes
Answer:
Dominant genes mask recessive genes.
Explanation:
Alleles are different variations of a gene. Every person has two alleles - one from each of their parents. Depending on whether it is expressed, an allele can be dominant or recessive.
A dominant allele is the one that is expressed even if the individual has one dominant and one recessive allele. This means that dominant alleles mask recessive alleles.
An example of a dominant allele is the one for brown eyes. This means that you need only one allele of this type to have brown eyes, which is why brown eyes are the most common.

What would happen to an organism if the enzymes that break down lipids were denatured?
Answer:
It will change shape and the substrate will no longer fit
Explanation:
if the enzymes that break down lipids were denatured, it will change shape and the substrate will no longer fit.
What are enzymes?Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Moreover, enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
Hence, enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced naturally in the body and help with important tasks, including: building muscle. destroying toxins.

Look at the diagram of a solar eclipse.
A solar eclipse with labels 1 through 4. 1: The moon. 2: A location on Earth directly in line with the center of the Sun and Moon. 3: A location above 2. 4: A location below and right of 2.
At which location is the solar eclipse viewed in totality?
Answer:
2
Explanation:
It is at the center of the area that gets to most attention.
At location 2 the solar eclipse will be viewed in totality. Therefore, at this point, the solar eclipse will be clearly visible.
What is a solar eclipse?A solar eclipse is a natural phenomenon which occurs when the Moon moves in front of the Sun and blocks some of Earth's view of it, either completely or partially. A similar arrangement happens roughly every six months, during the new moon phase of eclipse season, when the Moon's orbital plane is closest to the Earth's orbital plane.
In the case given here, at point 2 the eclipse will be visible clearly as the moon is precisely aligned between the earth and the sun at that location due to which the eclipse is focussed at that point.Therefore, the correct location is 2.

Weather and climate are affected by ocean currents because they
A. are caused by Earth’s rotation.
B. cause upwellings along certain coastlines.
C. move large volumes of water vertically in the deep ocean.
Answer:
C.
Explanation:
What causes currents in the ocean.Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Coriolis effect which also influences ocean currents.Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate.The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

What should be done before measuring an unknown pH of a solution using a pH meter?
Before measuring the pH of an unknown sample, the pH meter should be calibrated by putting in the buffer solution, and then only it can show the correct result of the sample that needs to be tested.
What is pH?pH explains and shows the result of the hydrogen ion concentration in the solution; the higher the concentration of hydrogen ions, the lower the pH. This is called acid in nature. The lower the concentration of this ion, the more value it shows and the more likely it is to be considered a basic solution.
The neutral value is 7, while the range above it is classified as basic and the range below it as acid. The pH of an unknown sample can be determined by using pH paper or a pH meter, but the pH meter is more accurate for the sample. The PH meter is first calibrated and put in the buffer mixture to get accurate data. Then it is inserted into the target solution.
Hence, the pH meter should be calibrated by putting in the buffer solution, and then only can it show the correct result of the sample that needs to be tested.

chewing that involves up/down, forward/backward, and side-to-side movements of the mandible is also known as Rotary chewing.
True or False?
Answer:
True
Explanation:
In the temporomandibular joint, there are two kinds of movements: rotation and translation.
Rotation is the movement around an axis. It is the movement of an object around its axes.
The mandibular rotation movement occurs in the condyles and might be produced in three planes: horizontal plane, frontal, and sagittal planes.
- Sagittal Plane: There are up/down, forward/backward movements involved.
- Horizontal Plane: These are lateral movements together with back and foward movements.
- Frontal: Involves up/down, and lateral movements.

How do parents' traits predict the offspring? (Explain)
Answer:
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. If a gene pair contains a dominant allele, then the offspring will show this dominant trait.
