Why do you think there were so many heated debates around the development of the cell theory?.
The debates around the development of the cell theory are fueled by the fact that yet there is no conclusive evidence about how the cell emerged in the geological past, thereby increasing the arrival of diverse theories.
What is the cell theory?The cell theory is a well-accepted scientific model that state all organisms are composed of one or more than one cell (the functional unit of all biological systems), which has been proved by empirical evidence.
The debates around this theory (the cell theory) are fueled by the fact that there is not conclusive evidence about the origin of the first primitive cells.
In conclusion, the debates around the development of the cell theory are fueled by the fact that yet there is no conclusive evidence about how the cell emerged in the geological past, thereby increasing the arrival of diverse theories.

Why does a pH of 5 produce high ATP synthase activity, but a pH of 3 and 9 very low ATP synthase activity?
Answer:
ATP synthase works best at a pH of 5, but changes in the pH of the medium can alter its enzymatic activity, decreasing it.
Explanation:
Enzymes are specialized proteins that contribute to biochemical reactions occurring faster, decreasing the activation energy.
Under ideal conditions of temperature and pH, enzymes can work at their maximum capacity, but changes in these conditions can affect the speed with which an enzyme acts.
ATP synthase, an important enzyme for ATP synthesis and oxidative phosphorylation, works best at a pH of 5 (weak acid), but as the acidity or alkalinity of the medium increases, enzymatic activity decreases.
How has evolution shaped human memory? 20pts
A population of ducks lives in an area that floods many times each year. Some of the ducks are better at finding food on dry land, while other ducks are better at finding food in wet, muddy areas. Eventually, the land around the lake permanently changes from dry soil to wet, marshy mud.
How will this change to the land most likely affect the duck population?
The population will remain stable because the ducks will not be affected by this kind of change.
The population will eventually balance out so that there are equal numbers of both types of ducks.
The population will evolve so that most ducks survive no matter how they find food.
The population will evolve so that most ducks are better at finding food in wet, muddy areas.
Answer:
D. A duck flies to another pond.
The above sentence is an example of emigration. Emigration refers to moving from one area to another for a long or permanent period. In this instance, a duck is leaving the pond it originally resided in (along a population other ducks) in order to reside in another pond. Therefore, it can be said that the duck "emigrated".

The diagram shown represents a cell that will undergo mitosis. Which diagrams below best illustrate the nuclei of the daughter cells that result from a normal mitotic cell division of the parent cell shown?
Diagram A best illustrates the nuclei of the daughter cells that result from a normal mitotic cell division.
Mitosis is a type of cell division by which a parental cell divides to produce two genetically identical daughter cells.In this case, the parental cell has three homo-logous pairs of chromosomes, thereby both daughter cells will also have three pairs of homo-logous chromosomes-Somatic (body) cells reproduce by mitosis, while germinal cells reproduce by meiosis.In conclusion, diagram A best illustrates the nuclei of the daughter cells that result from a normal mitotic cell division.

explain one way that HYDROGEN GAS is commercially produced
Explanation:
There are a number of ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.
Why do humans , bees , and flowers need glucose and not rocks ?
One of the most crucial chemicals in human biology is glucose, a six carbon aldose. Since glucose is a carbohydrate, it exists in a partially oxidized state and can give the cell a moderate amount of energy.
Because glucose is the primary catalyst for catabolism in all cells, it is significant. Since the cellular activities that comprise the complete TCA cycle and chemiosmosis rely mostly on glucose to supply energy, glucose is used to provide energy for cells. The products of each of the sequence of oxidations that glucose undergoes can effectively donate electrons, allowing them to be utilized for the process of oxidative phosphorylation to produce ATP.

India has a sharp rising trend and a quickly growing population, so it appears to be growing exponentially. It seems that Japan's carrying capacity has been achieved.
How do population growth and carrying capacity relate to one another?Growing populations may be impacted by increased density in a given area. The greatest number of a species that an ecosystem can sustain is referred to as the carrying capacity of a region. Carrying capacity is based on the amount of resources available (food, habitat, water).
What are some examples of exponential population growth?The term for this quick trend of population rise is exponential expansion. The best illustration of exponential development is found in bacteria. Via prokaryotic fission, prokaryotes, such as bacteria, divide.

a It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.
Answer:
A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
Explanation:
The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.
Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.

Why are elliptical galaxies important??
Answer:
Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they're frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies.
Explanation:
Answer:
Astronomers have identified and named more of the spiral galaxies because their swirling arms and brightness make them easier to spot. Elliptical galaxies are older and give off less light than other galaxies. They also have less dust and gas in them, so they don't form many new stars.

O A. An allele that mutates with each generation
B. An allele that is found on many genes
C. An allele present in all members of a population
ОО
D. An allele that formed by adaptive radiation
Answer:
C. An allele present in all members of a population
Explanation:
Just took the quiz
A fixed allele is an allele that is present in all members of a population and has a frequency of 100%. Therefore, option (C) is correct.
What is an allele?An allele is a variant form of a gene that arises through mutation and is located on a specific location on a chromosome, known as a locus. Genes code for specific traits or characteristics, such as eye color or blood type, and alleles determine the variations of these traits.
For example, the gene that determines eye color has several different alleles, including blue, green, and brown, which produce different variations of the trait.
Alleles can be dominant, meaning that they are always expressed in the phenotype of an organism, or recessive, meaning that they are only expressed when paired with another recessive allele. The combination of alleles that an individual inherits from their parents determines their unique genotype and phenotype.
