Answer:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects.
Explanation:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects are the animals that have a complete tube-like gut with two openings. A system having a tube with two openings i.e. mouth and an anus is called tubular system. In this tubular system, the animals eat with one opening and the other opening is used for excretion of waste and nitrogenous materials from the body so that's why most of the animals have two openings.

name the peocess used by living things to obtain energy
Answer:
All the organisms (plants and animals) require energy for performing various activities and maintaining their life. This energy is obtained by the breakdown of digested food during the process of respiration. The process of releasing energy from food is called respiration.
Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat those plants to obtain energy. Carnivores eat the herbivores, and decomposers digest plant and animal matter.
Two ways that living things get their energy is by, Cellular Respiration and Photosynthesis.
Cellular Respiration: Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Photosynthesis: it's process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by product.
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Describe the changes that occurred during the evolution of dogs from wolves?
Answer:
The dog, Canis familiaris, is a direct descendent of the gray wolf, Canis lupus: In other words, dogs as we know them are domesticated wolves. ... Not only their behavior changed; domestic dogs are different in form from wolves, mainly smaller and with shorter muzzles and smaller teeth.
Explanation:
hope this helps
Dogs were most likely domesticated by chance when wolves began following ancient hunter-gatherers to eat their garbage. The theory goes that docile wolves were given extra food scraps to help them survive and pass on their genes.
What is evolution?The gradual change in the genetic composition of the organism that led to the generation of new characters in the next generations is called evolution.
Dogs may have become domesticated because the forefathers had too much meat to eat. During the ice age, hunters and gatherers may have shared their surplus with wolves, who became their pets.
All dogs are descended from wolves, according to their ancestors. Gray wolves and dogs diverged about 15,000 to 40,000 years ago from an extinct wolf species.
Thus, it can be concluded that many changes occurred during the evolution of dogs from wolves.

How can the carrying capacity of an ecosystem change?
Answer: Carrying capacity can be decreased by disease, an increase in predation, hunting or harvesting by humans, a decrease in available habitat such as habitat destruction by humans, parasites, competition with another species for a resource, or changes in the weather that make the species less suited to the environment.

The statement which is not true about genetic disorders is that genetic disorders are curable.
What are genetic disorders ?A genetic disorder is a disease that is caused by a change, or mutation, in an individual's DNA sequence.
Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

What is natural selection? Describe the peppered moths example of natural selection. NO LINKS PLEASE
Natural selection is the mechanism by which beneficial alleles rise in frequency in the population over time.
The peppered moth is an example of natural selection acting to change the frequency of a certain trait in the population over time. During the Industrial Revolution, there was a directional change in the color of the peppered moth population around Manchester. That is, there was an increase in the frequency of dark colored peppered moths within the population. This was because the increased air pollution due to the industrial revolution created a situation where the dark colored version of the peppered moths had a higher relative fitness than the light colored peppered moths (which were the traditional variety). After pollution was reduced later on, there was a increase in frequency of light colored moths, as the dark colored moths no longer received a relative fitness benefit from their dark coloration.

Answer:
the Frequency remains constant
Answer: So if a wave slows down, its wavelength will decrease. ... Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

In two or more complete sentences, describe a scenario where human activities are related to an increase or decrease in blodiversity in an ecosystem. Write your answer in the essay box below
Answer:
Deforestation and loss of green areas so that factories can use those areas for their benefit, exploiting the natural resources around them decrease an ecosystem's biodiversity. The invasion of industrial areas and excessive use of their natural resources causes a disbalance in the ecosystem because the plants, water, nutrients, minerals, amongst other elements, are used by industries killing animals and species, reducing populations due to pollution, and lack of food.
Explanation:
An ecosystem is a system where animals and living organisms, such as plants or bacteria, live together with nonliving elements. Living organisms interact with each other and with nonliving ones to keep the system balanced.
We can define biodiversity as the variety of living things that exist in an ecosystem.
Human activities like deforestation and the building of big factories near areas with large amounts of natural resources lead to the killing of many species. As industries kill in excess species, or they pollute an ecosystem's soil and water, the species' population decreases. Asa result, there is a disbalance in the ecosystem.
A human activity that increases biodiversity is the protection of endangered animals or laws to protect natural areas where there are many species of plants and animals that are of high importance for the planet.
factors that affect on the characteristics of plants and animals.
Soil structure, pH, and its nutrient content affect the distribution of plants, which in turn influences the distribution of the animals that feed on them. Oxygen availability is an important abiotic factor affecting species in both aquatic and terrestrial environments.
