A possible hypothesis for this situation is that tank 1 contains denitrifying bacteria, tank 2 contains nitrite nitrifying bacteria, and tank 3 contains ammonia nitrifying bacteria.

A hypothesis, which is a common term used in experiments refers to a possible explanation for the results or phenomenon observed. In this case, a hypothesis needs to focus on the type of bacteria that are present in each of the tanks.

This means that to write a hypothesis we need to relate the type of bacteria to each of the tanks.

A frog that has more offspring than can survive on available resources is an example of overpopulation.

Overpopulation is a process whereby there are more individuals of a population than the available resources.

According to this question, a frog has more offsprings than can survive on available resources. This means that there are more frogs than resources.

Therefore, frog that has more offspring than can survive on available resources is an example of overpopulation.

Answer:

habitat loss, over-harvesting, and introduction of exotic species

Explanation:

The way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

The term "biodiversity loss" describes the decline in biodiversity brought on by the extinction or relocating of species. Some people might not consider the extinction of a certain species to be significant, especially if it is not a charismatic species such as the Bengal tiger or the humpback dolphin.

However, according to estimates from scientists, the present pace of species extinctions is several times higher than the background, or average, rate seen throughout Earth's history. Within our lifetimes, this amounts to the extinction of tens of thousands of species.

The breakdown of ecosystems is anticipated to have drastic repercussions on human welfare. Because of the intricate relationships between species, a loss of biodiversity may have a ripple effect on ecosystems.

One species' extinction, for instance, may result in the extermination of another. Scientists evaluate which species are in danger of extinction as well as the state of the ecosystems to gauge the loss of biodiversity.

Therefore, the way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

Answer:

faced a struggle for survival

Explanation:

The woolly mammoths became extinct, unlike the other species, because the woolly mammoths faced a struggle for survival due to changing of environmental conditions. Global warming is the main cause of extinction of woolly mammoth which destroy their habitats about 10,500 years ago. The environmental conditions are not favourable for them so they faced struggle for survival which causes extinction of woolly mammoth.

Answer:

5 g/cm²

Explanation:

Density = Mass/Volume = 20/4 = 5

Therefore, the density of the mineral is 5 g/cm². (Assuming those are the proper units).

Explanation:

d =mass/volume

d=20/4 =5

Answer: 4. Abnormal production of chain of Hemoglobin

Explanation:

Anemia is a condition where the cells in the body do not get enough oxygen because the red blood cells needed to transport them are either too little or are dysfunctional.

One way the red blood cells can be dysfunctional is when they have an abnormal type of hemoglobin. Hemoglobin is necessary in red blood cells to enable to transportation of oxygen and if it is dysfunctional, oxygen will have problems being transported which would lead to anemia.

Answer:

The correct answer is - NADH.

Explanation:

Glycolysis is a multistep part of cellular respiration in which food is broken down to give off energy in a form of ATP. In glycolysis, the end product is converted to Acetyl-CoA using the pyruvate dehydrogenase enzyme.

During the citric acid cycle and oxidative phosphorylation, there is NAD reduces and turns to NADH that moves to the mitochondria. It is converted to energy using redox reactions. Most of the energy from original glucose molecules are transported and exists in the forms of NAD to NADH.

Answer:

Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of high sodium concentration to the area of low sodium concentration

Explanation:

In this process, only water molecules can pass through the selectively permeable membrane. As the solution has different concentrations of solute, the water molecules will move from the more concentrated solution to the less concentrated solution. The process is called osmosis and is completed when both solutions have the same concentration.

Hi there!

We are given the hair types of two cats

The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair  

The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Answer:

The results may not be true for humans if the experiment used a model organism.

Explanation:

An animal model is an animal species used in research that mimics diverse human traits/features such as, for example, human response to certain diseases. Thus, animal models may provide useful information related to human developmental biology and human diseases (i.e., prevention, diagnosis, treatment, etc). However, in general, experiments involving animal models cannot be used to predict human outcomes. For example, in genetics, animal models exhibit different features to humans, including but not limited to genomes (i.e., different number and structure of chromosomes), genes, gene regulatory pathways, epigenetics gene regulatory mechanisms, etc. In consequence, animal tests may be unreliable and therefore their results cannot be directly extrapolated to human subjects.

Hi. Unfortunately, you didn't show the answer options, which makes it impossible for me to answer your question. However, I'm going to give you some general information about seeds that can help you find the right answer. Hope this helps you.

Seeds are structures responsible for plant proliferation. They exist only in gymnosperms and angiosperms and are absent in bryophytes and pteridophytes. All seeds are formed in the ovary of flowers as a result of the plant fertilization process.

All seeds are formed by three structures known as integument, nutrient and embryo. The embryo is what gives rise to another plant, which will grow after the seed is planted and germinates. Nutrients will be responsible for meeting the needs of the new plant during the beginning of its development. The integument, in turn, has the function of protecting the embryo.
