Answer:
The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%
Explanation:
A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.
In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

1. If you could zoom in really close to see what was happening on a petri dish, what do you think you
would see?
Answer:I need some points,, I hope y’all can understand
Explanation:
The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.
What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.

How do you know if something is alive? Describe some of the characteristics of living things.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
To be alive organisms have to include all of the following:
- Made up of a cell or cells
- Has DNA
- Can reproduce
- Responds to the environment
- Grows and develops
- Exchanges energy
- Evolves
Explanation:
Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.
45 / 10000 Word Limit Question 2 (b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
Answer:
Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water
Explanation:
In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.

In the question “How does pineapple consumption affect the number of digestive bacteria?”, pineapple consumption is
A) the control group B) independent Variable
C) dependent variable D) experimental group
Answer:
For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is the independent variable (option B).
Explanation:
The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.
The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.
According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the independent variable is the consumption of pineapple, which can be controlled and modified, while the characteristic that is under the influence of this variable is the amount of bacteria, so that the latter is the dependent variable.
The other options do not apply because:
The experimental (D) and control (A) groups refer to the population in which the study is conducted. The dependent variable (C), in this case, is the amount of digestive bacteria.Which is the correct ratio of Carbon Hydrogen Oxygen found in a carbohydrate? 2:21 1:1:2 0212 121

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

When you stop growing, your cells stop dividing.
True
False
Help please
Answer:
Absolutely not mitosis and meiosis don't stop until your heart stops beating.
It is false that When you stop growing, your cells stop dividing.
When you stop growing, it does not mean that all your cells stop dividing. In fact, cells in the human body continue to divide and replenish throughout life, albeit at different rates depending on the type of cell.
The human body is composed of various cell types that have different lifespans and rates of cell division. For example, cells in the skin, gastrointestinal lining, and blood undergo continuous division and turnover to replace old or damaged cells. These tissues are constantly renewing themselves.
However, some cells, such as neurons in the brain and muscle cells, have limited or no capacity for cell division after a certain stage of development. These cells primarily grow in size rather than dividing to create new cells. Therefore, not all cells in the body continue to divide once growth stops.

Some scientists today believe that adaptations are more caused or provoked by the fact of competition.
What is meant by Adaptation?Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.
Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.
Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.
