Answer:
Fossils
The fossil record of course shows evidence for evolution because the fossils of same species can perhaps change AND be found in difference places. The molecular record is true too because the DNA of the species are the same but their appearances look different. So you know that they had to adapt to their different environments.
I hope i was able to help you (:
The evolution can be studied with evidence. The genetic engineering process will not add evidence to the evolutionary study.
What is evolution?Evolution can be defined as the process of heritable changes in organisms over a period of time. The evidence of evolution helps in studying the evolution pattern and relation between the studies.
The evidence for evolution can be fossils, anatomy, observation in the traits, similarity in the DNA, and embryonic similarity.
Genetic engineering is the process of the alteration of genes. The process will not aid the evidence to the evolutionary study.

Rising temperatures in the Arctic Ocean can lead to large die offs of phytoplankton which are autotrophs what would most likely happen in an arctic ecosystem if the phytoplankton population decreased
Answer:
C. The populations of all other organisms in the food web would decrease because there would be less energy.
Answer:
C. The populations of all other organisms in the food web would decrease because there would be less energy.
Explanation:
In the Arctic ecosystem, phytoplankton is producers which synthesise food with the help of sunlight. In this ecosystem, zooplankton and krill are primary consumers as they feed on phytoplankton.
Arctic cod and bowhead whale are secondary consumers which feed on primary consumers. In the arctic ecosystem, the temperature is rising which is killing the phytoplankton.
If the phytoplankton population decreased, then all the consumers in the food chain in this ecosystem would decrease due to lack of food.
What can help convince developers to implement environment-friendly designs and materials during construction?
Answer:
In order to convince the developers proper petitions and incentives must be used.
Explanation:
The developers at the time of construction must be willing to applying eco-friendly designs and substances, and this can help in saving the environment for a longer time. Thus, in order to convince the developers, proper petitions and incentives must be applied.
If there would be no use of petition, then the developers may not use the eco-friendly substances at the time of construction, thus implementing petition would be an ideal step for the developers to use eco-friendly materials and designs.

George Brooks and his colleagues found that pyruvic acid produced through glycolysis can be used in aerobic respiration or converted to lactic acid in muscle cells, with lactic acid later being reconverted into pyruvic acid for further energy production. These findings have significant implications in athletic training, helping athletes understand how to manage lactic acid build up and utilize metabolic processes for optimizing muscular performance.
Explanation:George Brooks and his colleagues completed research into lactic acid in muscle cells. This research discovered that during exercise, pyruvic acid, formed as a product of glycolysis, can either be used in aerobic respiration or converted to lactic acid. This process involves the enzyme lactate dehydrogenase (LDH).
It was initially thought that an accumulation of lactic acid caused symptoms such as muscle stiffness, fatigue, and soreness. However, newer research conflicts with this. Now, it's understood that once lactic acid has been removed from the muscle and circulated to the liver, it can be reconverted into pyruvic acid and catabolized further for energy.
One significant application of these findings in the field of athletic training is understanding that in the absorptive state following intensive exercise, muscle cells can convert excess glucose to glycogen for storage. Additionally, amino acids are utilized in synthesizing actin and myosin, the proteins responsible for rebuilding muscle fibers.
Furthermore, understanding these metabolic processes in muscle fibers can help devise methods of training and recovery that optimize muscular performance. This understanding can also help individuals increase muscle endurance and delay fatigue by managing the buildup and removal of lactic acid in muscle cells during and after exercise.

Look at the sample of sedimentary rock to determine which fossil is the oldest.
A) 1
B) 2
C) 3
D) 5
Answer:
Option (D)- which is fossil 4, as given in the image
Explanation:
From the law of superposition of rocks, it is known that the rock layer forming the bottom of an undisturbed sedimentary sequence are the oldest rocks because they those sediments were first deposited there and due to compaction and lithification it formed a rock layer, and subsequently new sediments are deposited on top of it. The rocks that are found to be present at the apex portion of a rock sequence signifies the youngest rocks, where the recent sediments are deposited.
So the fossils present in the bottom layers will be oldest and those fossils that are present on the top rock layers are the youngest.
Thus, the fossil sample number 4 (trilobites), as given in the image is the oldest fossil.
Hence, the correct answer is option (D), which is fossil 4.
In the town of Edmonton, a breeze blows from the north during the day and toward the north in the evening. What is most likely located to the north of Edmonton?
A.
a desert
B.
a mountain range
C.
an ocean
D.
a forest
Answer:
C. an ocean
Explanation:
You should already know that the breeze leaves the place with the highest pressure and cold air towards the place with the lowest pressure and the warmest air. This movement is done as a way to balance pressure and temperature between these two locations.
During the day, the ocean is the place of great pressure and cooler air, so it is common that at that moment the breeze comes out of the ocean towards the terrestrial portion of the planet. However, at nightfall, the pressure of the ocean becomes lower and the air warmer than that of the land. The breeze at that moment makes the opposite way, leaving the land towards the ocean.
For this reason, we can say that the letter C is the correct answer to your question.

D. They show how certain compounds and elements move through the environment and are continually used and recycled
Please help!!
Answer:
D. They show how certain compounds and elements move through the environment and are continually used and recycled
Explanation:
The biogeochemical cycles are the cycles through which the chemical compounds are moving through the different spheres, both abiotic and biotic, and they get constantly used and constantly recycled through them. This basically means that the biogeochemical cycles are the ones that occupy every sphere, as they are what units all of the spheres. By moving through all of the spheres, the chemicals change their composition, getting used, dissolved, merged with other chemicals, and at the end they get recycled and the process continues all over again.
After three half- lives, a sample contains 10 grams of parent isotopes. How many grams of the parent isotope were present to start?
its not for biology..... its for Earth/Space Science
Answer: Initial amount of parent isotope present in the sample was 80 grams.
Explanation: Initial amount was= 80 grams
The sample undergone radioactive decay and after first half-life, it has= 40 grams (half of initial amount)
after second half-life, it has= 20 grams
And after third half-life, it has= 10 grams
Thus, the sample at present has 10 grams and initially had 80 grams of the parent isotope materials.
Answer:
The answer is 80
Explanation:
a half lives takes away half of an amount, in the question it said 3 half- lives.
the only posible answer is 80.
FIRST half lives: 80-40=40
SECOND half lives: 40-20=20
THIRD half lives: 20-10=10
80 is the only way to get to 10 with three half-lives.

I’m fairly sure that that is an animal cell
anna is working the study guide for her biology semester exam. The statement is made that ATP is required for ALL cellular functions. Anna is not sure this is true, so she starts generating a list of cellular processes she has studied this semester. She sorts them by processes that require ATP and those that do not. She concludes that while ATP is required for cellular processes requiring energy input, ATP is not a requirement of all cellular processes. Evaluate Anna’s list and her conclusion. Do you agree or disagree, why or why not?
Answer:
I agree with her.
Explanation:
ATP definitely is the most widely used high energy molecule - especially for cells. But, it is not absolutely necessary for some "passive" cellular mechanics. We can look at passive diffusion of cellular processes which may include; passive diffusion of water, or sugar molecular across a cellular membrane.
ATP is vital for energy-demanding cellular processes, like growth or movement, supporting its role as the 'energy currency for cells'. However, not every cellular process requires ATP. An example of this is passive transport, which typically functions along a concentration gradient, without the need for ATP.
Explanation:I agree with Anna’s conclusion. While ATP (adenosine triphosphate) is vital for many cellular processes, it is not required for all. ATP is known as the energy currency for cells. This means it is essential for energy-demanding processes, which include growth, movement, and active transport among others. During these processes, ATP is broken down, and a phosphate group or two are detached, supplying energy to the cell.
However, some cellular processes are non-energy demanding or have different mechanisms for acquiring the energy necessary. For instance, passive transport of materials across cell membranes occurs along a concentration gradient and does not typically require ATP. Hence, while ATP is incredibly important, and many cellular functions would be impossible without it, Anna is correct in her conclusion that it is not a requirement for every single cellular process.
