Answer:
the answer is D
Explanation:
Because when they are eaten their left over air goes into the other animals.
A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.
C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.
Answer:
The answer should be C
Explanation:
The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.
The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.
Answer: For building amino acids, proteins and nucleic acids.
Explanation:
Living cells requires nitrogen because they are major part of amino acids. They form the building block of protein and nucleic acids such as DNA which carry the genetic information and is passed from generations to generations. Plants and animal need nitrogen for growth and survival. The protein is use for building and repairing muscles and it is a necessity for growth.
Nitrogen is crucial for all cells as it forms the backbone of amino acids, proteins, and nucleic acids which perform essential roles in cell function.
All cells require nitrogen as an essential component for living organisms as it is an essential part of amino acids, proteins, and nucleic acids. Nitrogen forms the backbone of these molecules, which are fundamental structural and functional elements in cells. Amino acids are the building blocks of proteins, which perform many vital biological functions in cells. Similarly, nucleic acids, namely DNA and RNA, carry genetic information and are crucial in the synthesis of proteins. Without nitrogen, these molecules cannot exist and therefore, nitrogen is fundamental to all living organisms.

Answer:
Towards the southern of the sound
Explanation:
As the motion of the source of sound is moving,the percieved sound frequency varies .this is known as Doppler effect.the sound waves emited by the sources tends to bunch up in front of the source and spread out behind the source.
Since the falcon is moving towards the sound,the frequency increases and so does the pitch of the sound
B) axons of sensory neurons.
C) cell bodies of motor neurons
Answer:
C) cell bodies of sensory neurons
Explanation:
The dorsal root ganglia mainly contain cell bodies of sensory neurons.
See attachment for better visual understanding.
The dorsal root ganglia mainly contain cell bodies of motor neurons. The correct option is C.
Thus, Along the spinal cord are structures called dorsal root ganglia. They are a component of the peripheral nervous system and are mostly made up of sensory neurons' cell bodies.
These sensory neurons pick up sensory data from many body areas, including touch, temperature, pain, and proprioception (a sense of one's own bodily location).
The dorsal root ganglia serve as processing centres for incoming sensory information from the periphery before they are sent to the spinal cord and ultimately the brain for further decoding and action.
Thus, The dorsal root ganglia mainly contain cell bodies of motor neurons. The correct option is C.

Answer:
The Moon's gravity pulls more on the planet than the water on the opposite side. These two water bulges on opposite sides of the Earth aligned with the Moon are the high tides. Since ocean water is pulled higher in the areas of the two high tides, there is less water in between the two high tides.
