Answer:
sponges
Explanation:
because sponges need photosynthesis in order manufacture their food
The organisms namely sponges and coral animals are most likely to starve to death in the lack of photosynthetic endosymbionts. The correct option is 1 and 2.
What are endosymbionts?Endosymbionts are organisms that live in close proximity to another cell or organism.
As sponges are predominantly filter feeders, consuming detritus, plankton, viruses, and bacteria. They also absorb nutrient solution from water directly through their pinacocyte cells.
Due to the lack of photosynthetic endosymbionts the organisms namely sponges and coral animals are most likely to starve.

In the early 1900s, the Florida panther was found all over Florida. By 1967, the population had dropped to only 30 panthers statewide, and the panther was listed as an endangered species. What is the most likely reason for the decline in the panther population?
A. Florida's climate changed dramatically.
B. Panthers were hunted by humans for many years.
C. The panthers moved north into Georgia and South Carolina.
D. Alligators stopped eating other animals and started eating panthers.
Answer:
B.
Explanation:
Florida's climate itself hasn't particularly changed a bunch, but in the 20th century the population of Florida has increased. Plus D and C are easy to rule out. The easiest explanation for the panther's decline is the fragmentation of their habitat, and human interaction with the environment, not hunting per se. Good news is that the Florida panther's population has gone up to over 100!

Bacteria convert the nitrogen in the atmosphere into
a.Usable nitrogen
b.Non-usable nitrogen
Answer:
b. Usable nitrogen
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.

A company called Sierra Pacific Industries is destroying forests by a destructive and non-sustainable practice called clearcutting. This is being done at an alarming rate in specific counties in California.
A.Primary Succession
B.Secondary Succession
Answer:
Secondary succession.
Explanation:
Clearcutting leaves an area barren. It is a horrible practice and is opposed by every environmental group. There are better ways of logging without destroying the plant life present there. This is secondary succession because plant life did exist in the area that clear cut and will again if the logging company or the government will replant the area.

In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.
Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity in the neighborhood you chose.
Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.
Answer:
The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

Answer:
The correct answer is -
Adult body symmetry
The embryological formation of body cavities
Gene sequences
The number of tissue layers
Explanation:
Scientists and taxonomists use different criteria to assign different animals to particular phyla. The various systematic criteria that are used more frequently by systematists are as follows:
1. Adult body symmetry
Body symmetry is one of the criteria used to assign an organism or animal to a particular phylum. There is two symmetry found in animals radial and bilateral. If any plane passes through the middle axis and divides into two identical segments called radial symmetry and Bilateral symmetry is where only a single plane divides the body into halves. However, there are many animals that do not have any symmetry and called assymetrical.
2. The embryological formation of body cavities
Other than layers body cavities also helps in assigning the animals that depend on coelom - body cavity between the body wall and gut wall
Animals could be - coelomate(coelom present), pseudocoelomate -(not lined with mesoderm) and acoelomate(coelom absent).
Gene sequences
Genetic similarities also consider and how close an organism to their organism of the phylum or species.
The number of tissue layers
Different body parts, tissues, muscles, and organs developed from the different cell layers that are formed during embryo, therefore, called embryonic layers.
Animals on the basis of these embryonic layers could be diploblastic or triploblastic. Diploblastic animals form 2 embryonic layers the outer and inner layers called the ectoderm and the endoderm respectively. Triploblastic animals have an extra middle layer known mesoderm.

Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).

The examples of plant processes that involve an interaction between stems, roots, and leaves is water is transported up the stem from roots to leaves via the xylem. Hence option A, B an E is correct.
What is homeostasis?Homeostasis is defined as any self-regulating mechanism by which biological systems have a tendency to keep their stability while responding to environmental factors that are best for survival. The preservation of essentially constant internal conditions is referred to as homeostasis.
The xylem carries water up the stem from the roots to the leaves. Water must be absorbed by the root system in order for photosynthesis to occur in the leaves. The phloem circulates glucose produced by photosynthesis in the leaves throughout the plant.
Thus, the examples of plant processes that involve an interaction between stems, roots, and leaves is water is transported up the stem from roots to leaves via the xylem. Hence option A, B an E is correct.

How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.
Elephants are not the most common species in African grasslands. And although they are large, their combine biomass is really not that big compared to some of the combined biomass of plants in those habitats. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of the elephants. Take away the elephants, and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grasslands. What term best describes the role played by elephants in these communities
Answer:
This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.
Explanation:
The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.
Answer:
A. Keystone species.
Explanation:
A species that has huge impact on the other in the case when there is not much abundant species. In addition to this, it would keep the other populations in the ecosystem. Moreover, if the species would be removed so this would lead in diversity loss
So according to the given situation, the role that played by elephants in these communities is keystone species
