What is Cladogram?A cladogram is a representation of a potential link between groupings of species, including their shared ancestors. The Greek terms "clados" and "gramma," which mean "branch" and "character," respectively, are the origin of the words "cladogram."
The image gives the impression that a tree trunk is sprouting branches. Yet, the cladogram's form is not necessarily vertical. The diagram's sides, top, bottom, and center can all branch off of it.
Cladograms can be exceedingly complicated, potentially classifying all forms of life, or very simple, comparing only a few types of organisms.
Therefore, The frog has 2 limbs at the back and 2 on the front. a pigeon walks with its two tiny legs.

Answers
Answer is homeostasis
Explanation:
Homeostasis is the stable point of a cell
is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Describe what happens to these four substances during photosynthesis.
Answers
Answer:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
During photosynthesis, water and carbon dioxide in presence of sunlight are converted into glucose and determining product oxygen.
What do you mean by Cellular respiration?Cellular respiration may be defined as the process through which each cell can utilize energy from the glucose molecules broken down.
Being complex process photosynthesis converts light energy into chemical energy. The chlorophyll pigment of green plants captures sunlight and converts water and carbon dioxide into glucose (sugar), an energy compound, and oxygen.
Therefore, during photosynthesis, water and carbon dioxide in presence of sunlight are converted into glucose and determining product oxygen.

9. A section of a topographic map is shown below. X- 1600 1500 1400 1300 Contour interval: 20 m 1200- What is the difference in elevation in meters between Point X and Point Y on the map?
Answers
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
the elevation is increasing from southeast toward northwestthe difference in elevation between the contour lines is 20 mthe difference in elevation between the main contour lines is 100 mPoint X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.

Other immune cells attack the targeted pathogen by detecting its ______________. plz help due today will mark brainly
Answers
Answer:
An immune system identifies a pathogen by recognizing molecules on the surface of the microbe called epithelials. These cells send signals to the cytoplasm to produce chemicals called lipopolysaccharides that bind to the antigen and mark the pathogen for destruction. Other immune cells attack the target pathogen by detecting its immune system.
Explanation:
Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.) thus as for the commensal flora.

C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answers
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.
