No
Explanation:
These traits are not genetic, thus the parents do not carry the sex-specific Alleles to pass off to offspring.

What is the action force and the reaction force when someone swims?
No link
Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Answer:
the force is push and the reaction is moving forward.

A. electrons
B. isotopes
C. molecules
D. radiation
tysm!
Answer:
Isotopes
Explanation:
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes. Two terms we use to identify nuclides (isotopes) are atomic number and mass number.

what is the temperature at which enzymes work best and worst?
Answer:
There is a certain temperature at which an enzyme's catalytic activity is at its greatest which is 37.5 oC
Enzymes are still proteins, and as with all proteins, temperatures above 104 degrees Fahrenheit, 40 degrees Celsius, will start to break them down.
Explanation:
The temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius).There are also enzymes that work well at lower and higher temperatures.

A virus has wiped out the grasshopper population in the area. What effects to the ecosystem will most likely occur?
Answer:
Those who prey on grasshoppers will have their population decline while the grass population will rise.
Explanation:
Organisms need food to survive. If their food is gone, they won’t thrive as well. This isn’t saying they’ll go extinct, as they may have other food sources, but life will be harder with one food source gone. Since grasshoppers eat grass, the grass population will rise some due to a lack of predation. Hope it helps :)

Which of the following correctly matches a property of an organic molecule with how that property helps the organic molecule function in living organisms?
A. Carbohydrates lower the activation energy of certain reactions. This allows metabolic processes to take place at a rate that can sustain life.
B. Proteins contain nucleotides that encode genetic material. This allows proteins to accurately pass genetic information from one cell to another.
C. Nucleic acids contain multiple carbon-hydrogen bonds. This allows nucleic acids to provide energy for living organisms by breaking these bonds.

What process creates stalagmites? Group of answer choices Rivers carrying rocks down a mountain Windblown sand shaping large rocks Minerals being deposited as water drips Glaciers pushing large rocks
Answer:
Minerals being deposited as water drips.
Explanation:
Stalagmites grow on the floor of a cave. The process that creates them starts with the filtration of rainwater drops through the rock picking gases and minerals, amongst these ones is calcite. When the drops containing these elements pass through the rock and are in contact with the air, a chemical reaction happens. As a consequence, the calcite precipitate on the floor of the cave. This process has to happen many times to form a stalagmite.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.
What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.
integumentary and lymphatic systems
PLZZ HELP QUICKKK
The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

How is your body temperature held constant?
The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.

Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules
