Which best describes the way a sound wave is sent through the radio?
sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave
Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.
What is a sound wave?A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.
The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.
These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.
Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

explain reproduction in hydra
Answer:
Budding
Explanation:
The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent. Buds are produced every two to three days under favorable conditions. Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.

Tim does not need to factor his amino acid consumption into the total protein intake because they are components of protein, not full protein
Answer:
Yes.
Explanation:
Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid into total protein.

Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.

The correct answer is -
a) A plant cell B animal cell
b) nucleus
C) Vacuole
Explanation:
In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.
In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -

Animals release _____ into the atmosphere through _____
Answer:
animal release carbon dioxide into the atmosphere through respiration
Explanation:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.
Animals breathe, taking in oxygen and releasing carbon dioxide. Animals release carbon dioxide gas into the outer atmosphere through respiration process.
What is respiration?
This process completes in two steps: external respiration and internal respiration. External respiration, or breathing, includes inhaling (inhalation) oxygen from the outside atmosphere and exhaling (exhalation) carbon dioxide to outside. In this process, gas exchanges take place at the lungs, and deoxygenated blood oxygenates before going back to the left heart.
In cellular respiration, the cell takes oxygen from the oxygenated blood and uses it in different cellular metabolic reactions, releasing carbon dioxide into the blood. So in cellular respiration, oxygen is taken up by the cell and carbon dioxide is released by the cell. This carbon dioxide goes to the lungs, and by the process of exhalation, it is released into the atmosphere.
Hence, animals release carbon dioxide into the atmosphere through the respiration process.

After a devastating forest fire, the surrounding area contained no life. After some time, small plants began to grow along the remaining soil.
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: CORRECT (SELECTED)

The correct answer is given as follows:
Explanation:
Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.
In this case: 37 is the mean value that can be calculated by:
adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259
Number of sets = 7
then mean = 259/7
= 37
Thus, the mean can be calculated by total value divided by the number of sets

What is the relationship between capillaries and lymph vessels
Answer Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.
: Lymphatic capillaries collect lymph fluid from the tissues, which allows them to regulate the pressure of interstitial fluid. This fluid is essentially plasma that leaks out of cardiovascular capillaries into the tissues due to the forces of hydrostatic or oncotic pressure.

recessive alleles for a trait (heterozygous). What is the
probability of the offspring expressing the recessive
phenotype?
Answer:
25%.................
Answer:
D, 25%
Explanation:
We can do this with simple math! Since we have a 1:4 ratio of possibly expressing the recessive phenotype, we will do 1/4.
1/4 = .25
Then, we will multiply this by 100, which results in 25.
