The third law of motion states that for every action, there is an equal and opposite reaction. This can be observed both in objects at rest and those that are accelerating. For example, a resting box pushes down on the ground due to a gravitational force.
Thanks Hope it helps6. Which of the following is NOT true of the excretory system? a. Kidneys remove waste from the blood b. Removes waste from sweating c. Excretes feces d. Excretes urine
Kidney waste from sweating is not true of the excretory system.
The correct answer is option B.
What does the excretory system do?The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
What are the parts of the excretory system and their functions?The primary excretory organs in the human body are the kidneys, ureters, and urinary bladder, involved with the creation and expulsion of urine. Through these organs, much of the nitrogenous waste of the body, especially urea, is expelled.

When you were translating the mRNA to an amino acid sequence, where in the cell were you located?
And, on which organelle?
Answer:
It occurs in the organelle ribosome which can either be located in the cytoplasm or in the rough endoplasmic reticulum
Explanation:
This is because the translation of mRNA into amino acids forms proteins and as we know the organelle ribosome is responsible for synthesizing proteins
One way of representing the structure of an ecosystem is through ecological pyramids. Ecological pyramids represent the amount of organisms, biomass or energy at each tropic level, which most often is in a pyramidal shape. Why are most visual representations of ecosystems in the shape of a pyramid?
Select one:
a. Producers use a low amount of sunlight and produce a high amount of energy for all other organisms.
b. Very large carnivores (for example, wolves) have the most energy available to them from the trophic levels below.
c. The large number of primary consumers supplies a large amount of energy for fewer autotrophs.
d. At each trophic level, energy is lost (as heat) in the transfer of energy from one trophic level to another.

How would the finch populations on these islands change over time?
The finch population's beaks will be modified; on dry islands, they will have larger beaks, while on rainy islands, they will prefer medium or short beaks.
What is natural selection?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are more likely to survive and pass on the genes that helped them thrive. Species change and diverge as a result of this process.
Because of the differences in environmental conditions, the finch populations on the dry and wet islands are likely to change differently over time.
Finches with traits that allow them to efficiently extract nutrients from dry seeds would have an advantage on the dry island, where food and water resources are limited.
Natural selection would favour these traits over time, increasing the frequency of these advantageous traits within the dry island finch population.
Thus, this way, the finch populations on these islands change over time.

Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

What leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions?
A. less biodiversity
B.smaller food webs
C.greater biodiversity
D.specialist consumers
Answer: I think it’s C
Explanation: more biodiversity, the more reproduction and success.
Greater biodiversity leads to the likelihood that there are successful traits in an ecosystem. Therefore, option (C) is correct.
What is biodiversity?Biodiversity refers to the variety of species and the genetic diversity within those species that exist within an ecosystem. When an ecosystem has high levels of biodiversity, there is a greater chance that at least some species will have the traits necessary to survive and reproduce in changing conditions.
Organisms with successful traits in one set of conditions may not necessarily have those same traits in different conditions. Therefore, a diverse range of species with various sets of traits increases the likelihood that some of those traits will be beneficial in different conditions.

Which is one way that DNA replication is similar in eukaryotic cells and prokaryotic cells?
What is a mutagen?
A. A way to test for chromosomal mutations
B. A type of mutation involving chromosomes
C. An environmental agent that changes DNA
D. A mutation that is inherited from parents
The answer to the question is that Mutagen is an environmental agent that changes DNA.
Types of Mutagens:
Physical mutagens: Ionising radiation, such as X-rays, gamma rays, and alpha particles, is one example. UV radiations can also act as possible mutagens.Chemical mutagens: Mutagens include arsenic, nickel, and chromium. Some organic chemicals, such as benzene, are also mutagenic in nature.Biological mutagens: Transposonas and viruses are two examples of biological mutagens. Furthermore, some bacteria, such as Helicobacter pylori, have been linked to an increased risk of stomach cancer.Thus we can conclude that A mutagen is a physical or chemical substance that permanently alters genetic material in an organism, generally DNA, increasing the incidence of mutations over the natural background level.
