in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.
What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
Answer:
the process by which neutrophils ingest a bacterium
Explanation:
Neutrophils ingest bacteria via a process known as phagocytosis, or "cell eating." (also, I took the quiz)

The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
a. vital capacity
b. respiratory minute volume
c. pulmonary ventilation rate
d. alveolar ventilation rate
e. external respiration rate
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.
How have human activities effected the air in earth’s atmosphere?
Answer:
Human activities have had a negative impact on Earth's atmosphere.
Explanation:
Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.
This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.

What gametes are produced by the following organisms:_______.
a. Genotype YyRr, if Y and R are on different chromosomes
b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

Note: The question is incomplete. The complete question is found in the attachment below.
Explanation:
High temperatures or changes in pH can denature an enzyme, causing it to lose its shape and activity.
Enzymes speed up chemical reactions by lowering the activation energy which allows the reaction to proceed much more quickly.
An enzyme is considered a(n) catalyst because it speeds up a chemical reaction without being used up.
The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed.
A(n) inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.
During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product which are released.
The specific location within an enzyme molecule where the substrate binds is called the active site.
Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) enzyme.

Explain whether an experiment or an observational study would be more appropriate to investigate whether meditation is effective in lowering blood pressure.
Answer:
Experiment.
Explanation:
An experiment would be more appropriate method to investigate whether meditation is effective in lowering blood pressure because experiment has a control group as well as a testable group. Due to control group and testable group, we can easily find out the effect of meditation in lowering blood pressure if we apply meditation techniques to the testable group and compared it with the control group, we get results.

What is the role of carbon storage in organisms?? Plz answer fast in paragraph form if possible
Biological carbon storage happens when the carbon is stored in natural environment in animals and plants. This process includes what are known as carbon sinks, such as forests, grasslands, oceans, and other bodies of water.
What is Carbon storage?Carbon capture and storage is an attempt to remove the carbon dioxide gas from atmosphere after burning gas, oil, coal, or biomass before it actually enters the atmosphere, and to store it in the environment in various forms. Carbon storage has a success rate of between 50% to 68% of captured carbon, while aspirations of a 90% or 100% capture rate have not been achieved properly.
Carbon storage is carbon which is not emitted into the atmosphere. Less amount of carbon in the atmosphere will reduce the greenhouse gas effect and thus also lessens the impact of climate change and global warming.

What is true about cardiac (heart) cells compared to brain cells?
Different DNA which make different proteins
Same proteins being used to create different DNA
Same DNA being used to make different proteins
Different proteins used to create different DNA
Answer:
Same DNA being used to make different proteins
Explanation:
Cells of all living organisms contain the genetic material called DNA. One of the characteristics of multicellular cells is the ability of their cell to DIFFERENTIATE i.e. form specialized cells during division.
However, it is worthy to note that all cells possess the same DNA but some of the genes contained are expressed into proteins while others are not. This leads to why cells that contain similar DNA make different proteins and perform differently.
In this case, cardiac (heart) cells and brain cells contain the same DNA but due to the expression of some genes and repression of others, they are able to differentiate into different cells.
In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.

Identify the relationship described below:
Killer whales, also known as orcas, hunt and eat numerous other organisms — more than 140 species. However, orcas themselves are not hunted by any other organism. In other words, they are at the top of the food chain.
Group of answer choices
Mutualism
Parasitism
Commensalism
Competition
Predator-Prey
hi :)
The relationship described is predator-prey.
The orca is hunting and eating other organisms, which is known as a predator-prey relationship.
In case you need help with any more of these-
Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.
Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.
Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.
Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.

Describe the nervous response pathway when you taste something bad and spit it out. Using these keywords: stimulus, chemical receptor, sensory neurone, relay neurone, motor neurone, muscles, response, electrical impulse, chemicals
Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.
Explanation:
The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain. The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.
