the time interval required for the formation of two cells from one is called the
Answer:
The Generation Time.
Explanation:
When septum formation is complete the cell splits into two progeny cells. The time interval required for a bacterial cell to divide or for a population of bacterial cells to double is called the generation time.
Hope this helps!! Brainliest? Anyways have a great day!! :))
Cells are living entity, which undergo division for the continuity of life and transmitting genetic information.
The time interval required for the formation of two cells from one is called the generation time.
Generation time is defined as:
The time required for a bacterial cell or population of the bacteria to double in number is referred to as generation time. In general, generation time is the average interval of time required between the birth of an individual and the birth of offspring.
Thus, the generation time is the interval between the formation of two cells.

during dna replication the chromosomes contract and the identical halves are called
Answer:
Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.

If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same.True orFalse
Answer:
True
Explanation:
Temperature is the measure of average kinetic energy of objects, in this case it is water in a glass. If both temperatures are the same, then both average kinetic energies are the same.

in the process of respiration, organisms use carbon-based molecules to make __ and carbon dioxide.
Answer:
The products of respiration are CO2, Water Vapour and Energy.
C6H1206 + O2 ➔ CO2 + H20 + Energy
In the process of respiration, organisms use carbon-based molecules to make energy and carbon dioxide.
What do you mean by Respiration?Respiration may be defined as the process by which cells use oxygen to break down sugar and obtain energy.
The product of respiration depends on the condition where it is held. But the ultimate product that will definitely release is energy and carbon dioxide.

Why do we have high and low tides?
Answer:
It often accompanies a new moon and when the moon is closest to the Earth. The moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause high and low tides. Tides move around the Earth as bulges in the ocean.
during which of the following processes do sister chromatids separate from each other?
Answer:
Sister chromatids separate from each other during anaphase of mitosis and the anaphase II of meiosis II. During the anaphase stage of mitosis these chromatids separate and one chromatid goes into each daughter cell. During cell division they are separated from each other and each daughter cell receives one copy of the chromosome.

An ecosystem that can experience a disturbance without being fundamentally damaged is said to have: Inertia.
An ecosystem can be defined as a biological community or space that comprises all living organisms (biotic factors) and the physical environment (abiotic factors) with which they interact.
Basically, an ecosystem is responsible for the provision of the following essential services that are very vital and important for the sustenance of life in all living organisms;
Plant pollination.Water purification.Nutrient cycling.Additionally, an ecosystem is said to have an inertia if it experiences a disturbance or factor of changes without it being damaged significantly or fundamentally.
For example, the development of shrub forests during the Medieval Warm Period is an inertia of the ecosystem.

Resource partitioning reduces the number of species that can share a given resource.
True
False
Answer:
true
Explanation:
When two species compete with one another for the same resource, their niches overlap. Resource partitioning reduces the number of species that can share a given resource. Some bats prey on certain moths, hunting them using echolocation. i.e. bats, have evolved to change the frequency they use for echolocation.
at the end of glycolysis the carbons of glucose are converted to
