Answer:
The vertebral column and vestigial tailbones suggest a common evolutionary pattern among snakes, dogs, and humans, while the presence of limbs in dogs and humans but not in snakes highlights further diversification in their evolutionary paths.
Explanation:
The presence of a vertebral column in all three organisms suggests a common ancestry and evolutionary pattern. While snakes and dogs have tails, humans have vestigial tailbones that indicate a reduced or non-functional tail. This reflects an evolutionary change over time, where humans have lost their tails but still retain a remnant of the ancestral structure. Additionally, the presence of limbs in dogs and humans, but not in snakes, suggests further diversity and modification in the evolutionary patterns of these organisms.

The options attached to the question above are given below:
A. All living and nonliving things consist of one or more cells.
B. Cells and living organisms are spontaneously created.
C. Cells are the most complex unit of structure and function in living things.
D. A cell is the basic unit of structure and function of all organisms
ANSWER
The correct option is D.
The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.
the correct answer is d
Answer:
Chloroplast
Explanation:
Chloroplasts are organelles, small organs of plant cells, and other organisms capable of photosynthesis, such as algae.
They are green in color because of the presence of chlorophyll. It is in chloroplasts that the chemical reactions of photosynthesis occur.
In addition, these structures have DNA, RNA and ribosomes, so they can multiply and synthesize proteins naturally.
A chloroplast is a type of plastid in plants that contains chlorophyll for photosynthesis. This process uses sunlight, carbon dioxide, and water to produce glucose and oxygen. The chlorophyll appears green because it absorbs blue and red wavelengths of light but reflects green.
The plastid with chlorophyll in plants that photosynthesize is called a chloroplast. Chloroplasts are plant cell organelles that contain a green pigment called chlorophyll, which captures the energy of sunlight for photosynthesis. This process involves a series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen.
Photosynthetic eukaryotes, including plants and some protists, possess these chloroplasts. However, some bacteria also perform photosynthesis, but their chlorophyll is not located in chloroplasts but instead, within the cell itself.
All photosynthetic organisms contain a pigment called chlorophyll a, which humans perceive as green. This is because it absorbs wavelengths from either end of the visible spectrum (blue and red), but not green, which is reflected, making chlorophyll appear green.

B. identical to an entire single strand of DNA
C. double stranded and inside the nucleus
D. complamentary to part of one strand of DNA
During eukaryotic transcription, an RNA molecule is formed that is complementary to part of one strand of DNA.
During eukaryotic transcription, an RNA molecule is formed that is complementary to part of one strand of DNA. This RNA molecule, known as messenger RNA (mRNA), is transcribed from a specific gene and carries the genetic information from the DNA to the ribosome for protein synthesis. It is single-stranded and not double-stranded like DNA.
