Answer:
option 1
Explanation:
The size of most prokaryotic cells is about in diameter.
1-2µm
The size of most prokaryotic cells is about 1-2µm in diameter. Therefore option A is correct.
Most prokaryotic cells are relatively small, typically ranging in diameter from 1 to 2 micrometers (µm). Prokaryotes are unicellular organisms without a true nucleus or membrane-bound organelles.
Their small size is advantageous as it allows for efficient nutrient uptake and waste elimination, facilitating rapid growth and replication.
Despite their small size, prokaryotic cells are highly diverse and can be found in various environments, including soil, water, and even within the human body.
Therefore option A is correct.

Brad is swimming in the ocean on a hot sunny day. he finds the water to be much colder than the sand on the beach, even though the sun is warming them both. identify the reasons for brad’s observation. the water is colder than the sand because it requires more to change temperature. this is because the water has a higher than the sand.
Answer:
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up. The sand has a lower SHC so it requires less energy to heat up therefore heats faster and Brad will observe the sand to be hotter than the sea
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up.
What do you mean by specific heat capacity?The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
In thermodynamics, the specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity.
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.

The word transcribe means 'to write out' and the word translate means 'to express in a different language'. Review the meanings of transcription and translation in protein synthesis. How do the technical meanings of these words relate to meanings of the words in ordinary language.
The word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.
What is the genetic code?The genetic code is a series of instructions that indicate how to synthesize proteins from a given gene sequence.
During transcription, the DNA gene sequence is transcribed into a messenger RNA (mRNA).
During translation, triplets of nucleotides or codons in mRNA determine specific amino acids in the growing protein sequence.
In conclusion, the word transcribe means 'to pass the code from DNA to RNA', whereas the word translate means 'change from mRNA to protein', which is a different language.

Which of these describes ATP?
A. the site of photosynthesis
B. genetic material
C. energy storage
D. cell waste
Answer:
C
Explanation:
ATP has to do with energy so the correct answer would be energy storage.
The one that describes ATP is energy storage. The correct option is C.
What is ATP?A chemical that is a part of all living cells and gives energy to a variety of metabolic processes, including the production of RNA.
In patients with advanced solid tumors, the effects of laboratory-produced ATP on weight loss and muscle strength are being investigated. Likewise known as adenosine triphosphate.
The principal energy source for critical biological processes such muscular contraction, nerve impulse transmission, and protein synthesis is ATP generated in mitochondria.
For example, large levels of ATP signal that the cell has enough ATP and does not need to produce any more through cellular respiration. In this instance, a product "feeds back" to block its pathway, which is a form of feedback inhibition.
Thus, the correct option is C.

What are some possible benefits and dangers if the DNA is used to create a mutant form of the organism?
Explanation:
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Many other mutations have no effect on the organism because they are repaired beforeprotein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure below. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is likely to be prevented from dividing.

A basic permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached. They are non-vascular and made up of undifferentiated, primitive living cells that have undergone modifications to carry out distinct tasks.
Xylem, along with phloem and cambium, is a key component of vascular tissue. Its primary functions include providing mechanical support and storage as well as moving water and solutes from the plant-soil interface to the stems and leaves.
