Answer:
The correct order in which body structures would respond to changes in environmental conditions such as temperature is:
cell, tissue, organ, organ system, organism
The response to environmental changes typically begins at the cellular level, where individual cells detect and react to the changes. These cells then work together to form tissues, which collectively respond to the environmental stimuli. Organs, composed of different tissues, coordinate their activities to produce a response. Organs within an organ system work together to carry out specific functions related to the environmental change. Finally, the overall organism as a whole responds and adapts to the changes in its environment.

Explain how genetic information, along with an understanding of the process of descent with modification, enables scientists to reconstruct phylogenies that extend hundreds of millions of years back in time.
By comparing the DNA sequences of different species, scientists can identify shared ancestry and determine how closely related different species are. This enables them to make predictions about the evolutionary relationships between different species and to reconstruct phylogenies that extend back in time, providing insights into the evolutionary history of life on Earth. Molecular techniques, such as DNA sequencing, are particularly useful for this purpose because DNA is a stable, heritable molecule that is passed from one generation to the next.
What are Bald eagle homologous structures
The wing of a bald eagle is homologous to the wing of a penguin. Homologous structures are structures that are of similar evolutionary origin.
How do we explain?Homologous structures are described as anatomical features found in different species that have a common evolutionary origin. These structures may have different functions in different organisms, but they share a similar underlying structure and can be traced back to a common ancestor.
The wing of a bald eagle and the wing of a penguin are considered homologous structures because they both evolved from a common ancestral structure, even though they serve different purposes which is flight in the case of the bald eagle and swimming in the case of the penguin.

Carbon-14, a naturally occurring radioactive isotope of carbon, is found in the remains of organic matter. It has a half-life of 5,730 years, and decays as shown below.
The radioactive isotope containing carbon with the symbol C-14, often known as radiocarbon, has an atomic nucleus made up of 6 protons with 8 neutrons.
Carbon-14 is radioactive, but what kind?Due to its low energy beta emission, even very high concentrations of carbon-14 do not present a significant risk to those who are exposed. The outer, protective, dead layer of a body's epidermis is only just slightly penetrated by beta radiation.
Is the carbon-14 an isotope that exists naturally?Three isotopes of carbon are found in nature: carbon 13, that has 7 neutrons, carbon 14, that has 8 neutrons, and carbon 12, which now has 6 neutrons (6 protons = 12). There are various isotopes for each element. One little neutron can significantly alter an isotope's characteristics.

what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

What is transcription ?
During transcription, the DNA sequence is used as a template to synthesize an mRNA molecule, where each nucleotide in the DNA sequence is complementary to a nucleotide in the mRNA sequence. In RNA, the nucleotide uracil (U) replaces thymine (T) found in DNA. So, the complementary RNA sequence to the given DNA sequence will have uracil in place of thymine. Thus, the mRNA sequence will have the complementary sequence to the DNA sequence as shown above.
What is DNA?
DNA stands for deoxyribonucleic acid. It is a long molecule made up of repeating units called nucleotides. Each nucleotide consists of a sugar molecule called deoxyribose, a phosphate group, and one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T).

Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.
It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.
What are the important factors for the experiment?This experiment requires you to measure how acceleration changes if the mass changes. This implies you need to consider the following factors:
Acceleration: This factor is the one you will measure in your experiment.
Mass: This factor is the one you will need to control, this implies using objects from different masses and comparing if mas has any effect on acceleration.
Other: Net force, wind, etc. are other factors that need to be constant to prevent them affect the results.
Steps for the experiment:
Choose a specific heigh: One of the ways of measuring acceleration is to throw objects and determine the acceleration as they fall, so the first step will be to establish a height.
Throw different objects with different masses: You can begin with light objects and move into heavier objects.
Measure acceleration: Every time you throw an object, measure acceleration using the formula A = change in velocity/ time.

Describe Sex Cell?
Please put in full sentences and give an explanation and you will get thanks from me.
Don't forget the brainliest when I get one. I'm a beginner.
Answer:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.
Explanation:
A bacterial cell usually contains a single loop of DNA that is located in the cytoplasm of the cell and is not surrounded by a nuclear membrane. Some bacteria have additional loops of DNA called plasmids. Plasmids can be used for genetic engineering because DNA from other organisms can be spliced into a plasmid loop. For example, scientists in the late 20th century discovered a way to insert the portion of human DNA that codes for the protein insulin into plasmid E. coli bacteria. Which statement best explains why these genetically modified bacteria have been useful to society?
A. Human diabetics are now more resistant to bacteria
B. The bacteria are resistant to human diabetics
C. The bacteria can now make their own insulin
D. the bacteria are used to produce cheap insulin.
Answer: A is the correct answer.
because for the treatment of one type of diabetes insulin should be provided but isolation of insulin and production is so costly.
but as DNA recombination has developed we can use bacterial replication system to produce insulin. they replicate very fast so large amount of insulin will be produced and then it can isolated.
but we also know that insulin of bacteria needs some modification before it can be used in human.

(HELP ASAP, I WILL GIVE BRAINLEIST TO THE BEST ANSWER) How do you solve problems concerning 1 trait and 2 traits?
Answer:
1. Read the problem.
2. Determine what traits are dominant and which are recessive. Often you must marshal background knowledge to do this – which may not be explicitly mentioned in the problem.
3. Are any letters assigned to the genes? If not, make some up. We usually take the dominant characteristic and use the first letter of that word. For example, if polydactyly ( extra fingers ) is dominant over the normal five–fingered condition, we would pick P for the dominant gene, and small p for the recessive normal allele.
4. Determine, if possible, the genotypes of the parents. In 9 out of 10 problems this information is given, or at least implied. Sometimes you have to deduce it from other information given. Write it down so that you can remember what it is, e.g. Pp.
5. Determine all the possible kinds of gametes that can be made by each parent. Be careful, remember that a gamete can ordinarily receive only one gene of a pair of alleles. This is the part that most people have trouble with! e.g. P p.
6. Make a Punnett square, using each of the gametes for one parent across the top of each column, those of the other parent go vertically. If you have done step 5 properly you shouldn’t have any trouble with this step.
7. Work the cross carefully.
8. Now read the problem again. Find out exactly what it is asking for. Don’t assume too much. This is another place where many people get lost.
9. In most problems, these steps should get you through adequately. Some are slightly altered – for example, if the genotype of one of the parents is unknown, and that is what the problem wants you to discover. You may assign that parent something like A_ or __ genotype and see if that helps. Put the offspring genotypes in the square and work backward. Remember this won’t get all the problems – there is still nothing like real understanding – but it can help organize your attack on a genetic problem. and of curse, unless you understand the terms, such as homozygous, heterozygous, dominant, recessive, allele, and so on, you cannot begin to think of working problems.
10. Finally, the actual genetic information you need to solve these problems often appears concealed rather than revealed by the wording of the problem. learn to translate such a sentence, “Mary is normally pigmented but had an albino father”, into its logical consequence: “Mary is heterozygous for albinism” and then into “Mary is Cc”. Notice that, in this kind of a problem you may need to solve several subsidiary problems before you can proceed with the final solution.

Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food
Answer:
D. Increased availability of food
Explanation:
Trust
The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.
Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.
Thus, the correct option is D.
