What can be interpreted from the graph?
A)Number of microbes reduces with the time.
B)Number of microbes remains constant with time.
C)Number of microbes increases at a constant rate.
D)Number of microbes increases exponentially with time.
Answer:
The correct option is D) Number of microbes increases exponentially with time.
Explanation:
As we can see from the graph, the population of the microbes is starting with a slow growth in the start but as time increases, the population starts to grow in an exponential manner. Exponential growth occurs when there is enough supply of food and other resources to support growth. But with the passage of time, the resources will start to decline and we will see a decline phase after the exponential phase has occurred.

- Higher Order Thinking Nicole, Tasha,
Maria, and Joan each walk to school from
home. Nicole walks 1.11/12 miles. Tasha
walks 2.1/12miles. Maria walks 1.7/12miles.
Joan walks 2.2/12miles. How can you find
how much farther Joan walks to school
than Maria?
Answer:
Joan Walks [tex]\frac{7}{12}[/tex]miles farther than maria
Explanation:
Given:
Distance walked by Nicole = 1. 11/12 miles
Distance walked by Tasha= 2. 1/12 miles
Distance walked by Maria = 1. 7 /12 miles
Distance walked by Joan = 2. 2/12 miles
To find:
How much farther Joan walks to school than Maria = ?
Solution:
We can find the distance that Joan walk more than maria by subtraction
Joan distance - maria distance
here the distance are given in mixed fraction , so lets covert them into fraction and perform subtraction
=> [tex]2\frac{2}{12} - 1 \frac{7}{12}[/tex]
=>[tex]\frac{24+ 2}{12} - \frac{12 +7}{12}[/tex]
=>[tex]\frac{26}{12} - \frac{19}{12}[/tex]
=>[tex]\frac{26 - 19}{12}[/tex]
=>[tex]\frac{7}{12}[/tex]
Final answer:
To find out how much farther Joan walks to school than Maria, subtract Maria's walking distance (1.7/12 miles) from Joan's (2.2/12 miles), yielding a difference of 0.5 miles.
Explanation:
To find out how much farther Joan walks to school than Maria, we need to calculate the difference between the distances they walk. Joan walks 2.2/12 miles, and Maria walks 1.7/12 miles. To find the difference, we subtract Maria's distance from Joan's distance. This can be done by converting the fractions to twelfths to make it easier to subtract:
Joan: 2.2/12 milesMaria: 1.7/12 milesThe difference in the distances they walk to school is:
(2 + 2/12) miles - (1 + 7/12) miles = 1 + (2/12 - 7/12) miles = 1 - 5/12 miles.
Therefore, Joan walks 0.5 miles farther to school than Maria.
According to the text, what happens when organisms cannot adapt to changes in their environment?
A. They move to another environment.
B. They risk dying out.
C. Nothing happens.
D. They wait for the environment to change again.
Answer:
The correct options are A) They move to another environment.
B) They risk dying out.
Explanation:
According to natural selection, only those organisms are able to live and survive in an environment which can adapt to the changes in an environment. Such organisms reproduce and pass on their characteristics to their offsprings.
Organisms which are not able to adapt to changes in an environment either migrate to other places or die as they are not able to survive by the changes being made.
If organisms can't adapt to environmental changes, they risk dying out, which can lead to extinction. Adaptation is key for maintaining internal stability and handling external changes.
Explanation:When organisms cannot adapt to changes in their environment, they risk dying out. The inability to adapt may lead to extinction, as has happened with the majority of species in evolutionary history. Adaptation is crucial for survival because it enables organisms to maintain their internal environments and respond to external changes. If a species develops a disadvantageous mutation, competing species that remain unchanged could become relatively better adapted without any change on their part. This concept reflects the importance of continuous adaptation just to maintain a species relative standing in its ecosystem.
what’s an independent and dependent variable
Answer:Independent Variable
A variable that you (the scientist) changes and you have control over. The factor being tested in an experiment.
Dependent Variables
Factor(s) that change in response to other factors. It's what your measuring in your experiment to see whether or not the independent variable made an impact. This is what the scientist focuses their observations.
Explanation:
Answer:

Which makes viral infections difficult to defend?
A.) the immune system must attack the body’s own cells
B.) viruses are attacked by a nonspecific immune response
C.) viruses live outside of cells
D.) macrophages work slowly
Answer:
Viral infections are difficult to defend as viruses are attacked by a nonspecific immune response.
Explanation:
Viral infections often tend to weaken the immune system of the body by turning it incapable of fighting the virus. Any external drug administered to fight the virus also leaves an impact on the beneficial cells causing them to cause side effects. The response of the immune system to the virus often fails to address the root of the virus and hence, the virus keeps growing stronger.please help asap

Burning a nut raises the temperature of 100 grams of water from 20 degrees C to 60 degrees C. How much heat does the water gain? Heat is measured in calories. 1 calorie = 4.18 J
Answer:
16 KJ or 16,720 J energy has gained by the water.
Explanation:
Given data:
Mass of water = m = 100 g
Temperature difference = ΔT= (60 - 20)∘C
specific heat of water 1 calorie = c = 4.18 J
To find:
Heat absorbed by water = q=?
Formula:
q = m . c . ΔT
Solution:
q = (100 g) x (4.18J/g ∘C) x (60 - 20)∘C
= 16,720 J
Final answer:
The water gains 4,000 small calories (cal) or 4 large calories (Cal) of heat when a nut is burned and raises the temperature of the water from 20°C to 60°C.
Explanation:
To calculate the amount of heat gained by the water when a nut is burned, we can use the formula:
Q = mcΔT
where:
Q is the heat in calories,
m is the mass of the water in grams,
c is the specific heat capacity of water (1 cal/g°C),
ΔT is the change in temperature in degrees Celsius (°C).
Given:
m = 100 g,
ΔT = 60°C - 20°C = 40°C.
Plugging the values into the formula:
Q = 100 g × 1 cal/g°C × 40°C = 4000 cal
Since 1,000 small calories (cal) make up 1 large calorie (Cal), the heat gain in large calories would be:
4 large Cal (since 4000 cal / 1000 = 4 Cal).

Explanation:
BRAINLIEST
Part A: explain my process to his important to sexual reproduction.
Part B: identify processes 1 and 3. State one difference between the cells produced by process with 3.
Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
Sexual reproduction involves meiosis and the fusion of gametes to produce genetically distinct organisms.
Explanation:Sexual reproduction involves the process of meiosis, which produces haploid cells called gametes. These gametes from two different organisms fuse together, forming a new diploid cell, a zygote. This fusion of gametes generates a genetically distinct organism.
Process 1: Meiosis - Meiosis is the process in which a diploid cell divides twice to produce four haploid cells. These haploid cells are the gametes. The main difference between the cells produced by meiosis and those produced by process 3 is that the cells produced by meiosis are genetically distinct from each other, while the cells produced by process 3 are genetically identical to each other.
Process 3: Fusion of Gametes - The fusion of gametes from two different organisms results in the formation of a new diploid cell, a zygote. This zygote develops into a new organism.
Peppered moth simulation
Answer:
yes
Explanation:
because
The Peppered Moth Simulation is a biological illustration of natural selection. The color of these moths changed in response to industrial pollution in 19th-century England, with darker moths having a survival advantage because they were better camouflaged. This color balance has been shifting back as air quality improves.
The Peppered Moth Simulation is a classic example of adaptation and survival in biology, often used to demonstrate the concept of natural selection.
In the mid-19th century, nearly all peppered moths in industrialized areas of England were dark (or 'melanic'), whereas before industrial pollution the majority were 'typica' or lighter colored. The color change is believed to have been a response to pollution: dark moths were better camouflaged against soot-covered trees and therefore less likely to be eaten by birds. This is known as industrial melanism.
Tests carried out in various ways have shown that the large changes in frequency of the dark moth could not have happened by chance, which indicates natural selection. With improvements in air quality, the 'typica' variety of the moth is again predominant today.

Final answer:
Research is vital for creating evidence-based public policy and informed personal decisions, as well as for demonstrating scientific links, like those between smoking and cancer. Studies' replication ensures the validity and reliability of findings, which is essential in fields that impact public health and policy.
Explanation:
Research is significant for various reasons, particularly in guiding public policy and personal decisions with evidence-based findings. One reason research is important is that it allows scientific demonstrations of links between phenomena, such as how early longitudinal studies by the American Cancer Society showed connections between smoking and increased cancer rates. Another reason is that replicating studies strengthens the reliability of the findings, providing confidence that results are not due to chance or specific conditions. In addition, by using archival or secondary data, researchers lay a solid foundation for developing their central research questions and conducting thorough investigations.
For researchers, it is paramount that others attempt to replicate their studies to ensure that the findings are valid and not an anomaly. This replication contributes to the strength of scientific evidence and eventually, to consensus within the scientific community on certain issues. This is crucial in psychological research and any field where understanding behavior and its implications can significantly affect public health, policy, and individual life choices.
