Photosynthesis -is a process in which plants use to make their food by the help of sunlight
Cellular respiration- means the break down of simple sugars into CO2 and H2O and release energy in the form of ATP . so it takes place in all living things ,in plants and also in animals.
ventilation -means breathing in other word so every living thing doesn't live without breathing .
Absorb sunlight - it is done by plants to make their own food.
Make glucose-plants and animals both use glucose as their main source of energy. The main source of glucose in animals include the diet and process of gluconeogenesis and the primary source in a plants is the process of photosynthesis .

Does every environmental change lead to an adaptation?
Answers
Yes, most of environmental changes lead to an adaptation.
Adaptation is a process of deliberate change in anticipation of or in reaction to external stimuli and stress. The dominant research tradition on adaptation to environmental change primarily takes an actor-centered view, focusing on the agency of social actors to respond to specific environmental stimuli and emphasizing the reduction of vulnerabilities. The resilience approach is systems orientated, takes a more dynamic view, and sees adaptive capacity as a core feature of resilient social-ecological systems. The two approaches converge in identifying the necessary components of adaptation. We argue that resilience provides a useful framework to analyze adaptation processes and identify appropriate policy responses. We distinguish between incremental adjustment and transformative action and demonstrate that the sources of resilience for taking adaptive action are common across scales. These are the inherent system characteristics that absorb perturbations without losing function, networks, and social capital that allow autonomous action and resources that promote institutional learning.

Reproductive isolation is a type of isolation that occurs when two populations of organisms are unable to interbreed and produce viable offspring.
There are several types of reproductive isolation, including behavioral isolation, anatomical isolation, and chromosomal isolation. In the case of horses and donkeys, their offspring, called mules, are sterile and cannot produce viable offspring. This is an example of reproductive barrier, specifically chromosomal isolation.
12. Horses and donkeys are different species, and they have different numbers of chromosomes. Horses have 64 chromosomes, while donkeys have 62 chromosomes. When horses and donkeys breed, their offspring have a combination of chromosomes from each parent that is not viable, resulting in sterility.
Behavioral isolation is a type of reproductive isolation that occurs when two populations of organisms are unable to interbreed due to differences in behavior, such as seasonal migration or courtship displays. Anatomical isolation is a type of reproductive isolation that occurs when two populations of organisms have physical differences.

how is the right optic tract anatomically different from the right optic nerve
Answers
The right optic tract is a fiber bundle that carries visual information from the right visual field of both eyes to the brain, while the right optic nerve is a cranial nerve that carries visual information from the right eye only.
The optic nerve is a paired cranial nerve that originates from the back of each eye and carries visual information from the retina to the brain. The right optic nerve carries visual signals from the right eye specifically, while the left optic nerve carries signals from the left eye.
After leaving the eye, the fibers from the nasal (inner) half of each retina cross over at the optic chiasm, resulting in the right optic tract carrying information from the right visual field of both eyes. On the other hand, the temporal (outer) half of each retina does not cross over, so the left optic tract carries information from the left visual field of both eyes.
In summary, the right optic tract carries visual information from the right visual field of both eyes, while the right optic nerve carries information exclusively from the right eye. The anatomical difference lies in the scope of visual field each structure represents.

Answers
The specific expression pattern of gene X in nerve cells is likely contributed by the presence of a sequence-specific DNA-binding activator that is not present in other tissues. This activator helps regulate the expression of gene X by enabling RNA polymerase II to bind effectively and allowing transcription to occur in a tissue-specific manner.
The specific expression pattern of gene X in nerve cells is most likely due to the presence of a sequence-specific DNA-binding protein. This activator is present in some tissues, such as nerve cells, but not in others, like liver cells. The activator's function is to bind to a particular DNA sequence and facilitate the transcription process by enabling RNA polymerase II to bind effectively.
In the case of gene X, its expression produces large amounts of tRNA but undetectable amounts of mRNA, suggesting that the activator plays a crucial role in the regulation and selective expression of this gene.
Additionally, general transcription factors can inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II. This further supports the importance of the activator in the tissue-specific expression of gene X.

Answer:
A The oldest rock layer will occur at the bottom of the sequence
Explanation:
Answer:
A) At the bottom of the sequence
Explanation:
If undisturbed, rock layers will build up with time, leaving the oldest ones on the bottom as new layers are on the top.
The Earth is made up of four layers. From the inside out, there is the inner core, outer core, mantle and crust. The core is about as hot as the surface of the sun. Heat energy from the core is constantly trying to escape. This energy continually pushes outward toward the mantle and crust. The crust usually keeps the mantle contained below, but not always! Earth’s crust is broken up into about 15 different pieces called tectonic plates. The boundaries between these plates are called faults. At these fault lines, magma—molten rock from the mantle mixed with hot gas—can build up. Volcanoes are openings in the ground found at these fault lines. When the pressure beneath Earth’s surface becomes too much, magma releases from deep inside the Earth through a volcano. Once it reaches Earth’s surface, magma is called lava.
Which of the following best describes the relationship between Earth’s crust and tectonic plates?
A
Earth’s crust is one large tectonic plate.
B
Earth’s crust is found between the outer core and tectonic plates.
C
Earth’s crust is made up of separate pieces called tectonic plates.
D
Earth’s crust sits above tectonic plates, which are suspended in the mantle.
Answers
The following best describes the relationship between Earth’s crust and tectonic plates: The earth's crust is made up of separate pieces called tectonic plates, which are in option C.
What is the earth?The earth's crust is the outermost layer of the earth, and it is not a single solid piece but is broken up into a number of large and small pieces known as tectonic plates. These plates float on the molten rock of the mantle, which is located below the crust. The movement of these plates is driven by convection currents in the mantle. As the plates move, they can collide with each other, move apart, or slide past each other. The boundaries where the plates meet are known as plate boundaries or faults. These plate boundaries are where most earthquakes and volcanic eruptions occur.
Hence, the following best describes the relationship between the Earth’s crust and tectonic plates: The earth's crust is made up of separate pieces called tectonic plates, which are in option C.

It adds new DNA to both strands of the telomere overhang. C. It adds new DNA to the longer strand of the telomere overhang. D. It makes special primers that do not need to be removed. E. It synthesizes new DNA without the use of a template.
Answers
The function of telomerase at the telomere is to add new DNA to the shorter strand of the telomere overhang.
Telomeres are the protective caps at the end of each chromosome, which consist of repeated DNA sequences that shorten with each cell division. Telomerase is an enzyme that adds new DNA to the telomere, which helps to maintain its length and prevent it from getting too short.
This is important because when the telomere becomes too short, it can no longer protect the chromosome from damage, which can lead to cell death or mutations that can cause diseases like cancer. Therefore, telomerase plays a critical role in maintaining the stability and integrity of the genome. Option A is the correct answer.

For the transformation of bacteria lab (to transform e. coli bacteria with a gene encoding green fluorescent protein -GFP using pGLO plasmid along with LB agar and ampicillin),
1. What new gene (s) were you looking for in the transformed E. coli?
2. Why do you expect colonies on the ampicillin agar to fluoresce?
3. How could you rule out contamination? Mutation?
4. Why was the discovery of GFP so noteworthy?
Answers
In the transformation of bacteria lab, we were looking for the gene encoding green fluorescent protein (GFP) in the transformed E. coli.
1. In the transformation of bacteria lab, we were looking for the gene encoding green fluorescent protein (GFP) in the transformed E. coli. The pGLO plasmid used in the transformation contains a gene for ampicillin resistance and a gene for GFP expression under the control of an arabinose-inducible promoter. By transforming E. coli with this plasmid, we introduce the GFP gene into the bacterial genome, and if successful, the transformed bacteria will express GFP.
2. The ampicillin agar used in the transformation contains ampicillin, an antibiotic that kills bacteria that do not have the ampicillin resistance gene. The pGLO plasmid contains the ampicillin resistance gene, so any transformed E. coli that have taken up the plasmid will be resistant to ampicillin. Therefore, we expect colonies on the ampicillin agar to fluoresce because they contain transformed E. coli that express GFP and are resistant to ampicillin.
3. To rule out contamination, we can perform controls such as using sterile technique during the experiment, using sterile media and reagents, and running negative controls with non-transformed E. coli. To rule out mutation, we can perform genetic sequencing to confirm that the GFP gene is present and has not undergone any mutations.
4. The discovery of GFP was so noteworthy because it revolutionized the field of cell biology by allowing researchers to visualize and track cellular processes in real-time. Prior to the discovery of GFP, researchers had to use dyes and stains to visualize cells, which often required fixation and killed the cells. With GFP, live cells could be imaged and tracked over time, providing a wealth of information on cellular dynamics and function. GFP has since been used in a wide range of applications, including genetic engineering, cancer research, and neuroscience.

Why does a plant need to store glucose...
Answers
Answer:
Because glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That's why some foods that we eat, like rice and grains, are packed with starch.
Explanation:
Sugars facilitate the assimilation of nutrient elements and their transport by the plant since they reduce osmotic pressure, thus improving their entry into plant tissues. During vegetative development, transport takes place towards the stem and root tips.
