Answer:
The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells. The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).
Explanation:
Blood type is controlled by the inheritance of any two of the following alleles: IA, IB, or i. IA codes for type A blood. IB codes for Type B blood. Both IA and IB are codominant. The i allele is recessive and will cause Type O blood whenever two copies of the allele are present.
If a mother has Type AB blood (IAIB) and a father has Type O blood (ii), what percentage of their children are likely to have Type A blood?
A. 25%

Assume that a DNA double helix contains 100 base pairs (one pair is A-T or C-G) and there are 45 cytosines.
a. How many guanines are there?
b. How many adenines are there?
Cytosine(C) binds with Guanine(C)
Adenine(A) binds with Thymine(T)
a.From here we can deduct that there are the same number of nucleotides of guanine that as cytosine=>G=45 base pairs
b.2A=100-G-C
2A=100-90 2A=10 A=5 base pairs
All living organisms, including animals, plants, fungi, bacteria, and protists, must perform certain processes in order to survive. For
example, all living organisms must be able to obtain energy so they can use that energy to perform their life functions. In what part
of a living organism do these life functions occur?
Answer:
the cell im assuming. wait for another answer tho because I could be wrong
Answer: D. cells
Explanation: Green plants and some bacteria and protists obtain energy by absorbing light energy from the Sun to make sugar, a process known as photosynthesis. Animals, fungi, and other bacteria and protists obtain energy by consuming plants or other organisms. Then, once the energy is obtained, the energy is released through a process known as cellular respiration.
These life functions (e.g., waste breakdown and removal, growth and division, transport, respiration) occur in the cells of organisms, and these functions are similar in different organisms.
What is the relationship between the Earth, moon, and Sun during a solar and Lunar eclipse?
Answer: The relationship between the Earth, moon, and sun during a solar and Lunar eclipse is Lunar eclipses only happen once the Moon is in the opposite direction of the Sun in the sky, a montly occurence, which is known as a full moon.
Explanation: Once the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When this happens, Earth passes directly between the Sun and the Moon, which causes its shadow to create a lunar eclipse.
Answer:
during a luner eclipse the earth comes between the sun and the sun and the moon blockimg the sunlight falling on the moon.

Answer:
C, is the answer
Explanation:
Option C. sound vibrations are converted to nerve impulses.
What is in the cochlea?The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact, takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turn around a hollow central pillar, the modiolus.
What is the main function of the cochlea?The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.

Describe the steps of protein synthesis in a eukaryote.
The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.
The second step is translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.
Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.
What is protein synthesis in a eukaryote?The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.

Which statement best-describes the function of the human body system in the above diagram
Answer:
Supplies oxygen to blood and removes carbon dioxide from blood
Explanation:
hope it helps
“Although part of your question is missing, you might be referring to this full question: Which statement best describes the function of the human body system in the above diagram (Refer to attached diagram)?
a) Produces and secretes hormones that regulate metabolism, growth, and development
b) Provides support and movement for the body
c) Breaks down food into nutrients and wastes
d) Supplies oxygen to blood and removes carbon dioxide from the blood”
The statement that best describes the function of the human body system in the given diagram is “Supplies oxygen to the blood and removes carbon dioxide from the blood”. Hence, option (d) is the correct answer.
The human body system in the given diagram is the respiratory system. The characteristics and function of the respiratory system are described as follows:
The respiratory system includes lungs, airways, and blood vessels It is the organs and tissues network that helps the individuals to breathe The primary role of the system is to move oxygen throughout the body with the help of blood and remove the waste gases like carbon dioxide from the blood that is obtained from various organsThus, we can conclude that the function of the respiratory system is defined by the statement " Supplies oxygen to the blood and removes carbon dioxide from the blood”. Hence, option (d) is the correct answer.
