Answer:
When a single-celled organism splits into 2 new organisms it is called fission.
When a single-celled organism splits into 2 new organisms it is called fission. Therefore, option (A) is correct.
What is binary fission?In biology, fission is the split of a single organism into two or more pieces, followed by the regeneration of those parts into new, distinct organisms that resemble the original. Cells are often the thing that undergoes fission, although the phrase may also describe how creatures, bodies, populations, or species divide into distinct sections.
Asexual reproduction in bacteria occurs via a mechanism called binary fission. A single organism splits into two separate ones during binary fission. The duplication of organelles in eukaryotes is sometimes referred to as binary fission.

Explanation:
Why does the cell sometimes have to expend energy to move individual molecules across the cell membrane?
Answer:
Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.
Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.
Under ideal laboratory conditions the rate of growth of bacteria is proportional to the size of the population at time tt. Suppose that 21002100 bacteria are present initially and that 42004200 are present 1 hour later. How many bacteria are there at the end of 55 hours?
Answer:
The amount of bacteria that are there at the end of 55 hours is 2310231000
Explanation:
From the description in the question, the bacteria's population size doubles per hour;
Within 1 hour = 21002100 × 2 = 42004200
Thus
After 1 hr ⇒ 42004200
55 hrs ⇒ ?
? = 55 × 42004200 = 2310231000
The amount of bacteria that are there at the end of 55 hours is 2310231000

Write a paragraph 4-5 sentences as to which one you think is better sexual or asexual reproduction
Answer:
Asexual
Explanation:
I think Asexual reproduction is better because you only need one reproduction Creature. For example plants, they are asexual so they do not need to worry about mating. Instead they can just create more plants by doing nothing. This helps us because we get more plants in a shorter amount of time. another example of Asexual reproduction is cross-pollination which is also an amazing way of creating more plants in a shorter time.

Relative dating techniques have been around for hundreds of years. How did newer
absolute dating techniques change the way we look at seologic cross section
It allowed us to put reologie cross sections lo better order
It allowed us to put a formation date on some geologic crosections
It allowed us to disprove the existence of land bridges
It allowed us to start using the idea of superposition
Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.
What was the result of using drainage blocks to keep water in the field level during the growing season?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

How is energy converted and stored in the process of photosynthesis?
During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.
What is photosynthesis?Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore,During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.
Answer:
The correct answer is - option D. 1/2
Explanation:
Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.
In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.

Man = Dd
Woman = dd
Their children :
D d
d Dd dd
d Dd dd
Probability of polydactyl child = 2/4 or 1/2 or 50%

A biologist from another galaxy might think that automobiles are a dominant form of life on planet Earth. Automobiles move, consume gasoline and oil, and produce wastes. They are sheltered in garages and respond to stimuli. Automobiles age and break down, but new automobiles appear every year. They evolve, changing in appearance from year to year.
What arguments would you use to persuade the alien visitor that cars are not alive?
Answer:
Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.
Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Answer:
Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Explanation:
It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.
