Neuron-  the level of organisation is cells.Because it s the functioning unit of nervous system.

The Blood's level of organisation is  tissues because if is made of group of cells.

The stomach level of organisation is organ, because it is made up of group of cells and tissues to form part of the digestive system.

Heart muscles is made up of organs as it is the combination of tissues and cells therefore a muscular organ,

DNA -represents a molecular level,but because it is located in the cells , its represented this level.

Egg belongs to level of organisation which is cellular.

Oxygen atom level of organisation is.(cell)

water is a Compound.( tissues )since it is the combination of two atom cells( hydrogen and Oxygen)

Human being is organism.

electron level of organisations are the smallest particles.(cells)

Answer:

The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.

There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.

In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.

Explanation:

In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.

This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.

The loss of Artic ice is negative between human population. It will cause human population who live in coastal areas in the artic circle will have to deal with erosion on the coast lines.

Answer:

Chromosomal rearrangment was not the cause because it wouldn't lead the mass of DNA per cell in Calix to appreciate by 40fg. It also wouldn't explain how he ended up with an additional sex chromosome altogether.

Explanation:

Nonnative species is defined as the introduction of an alien species, foreign species or exotic species to a new region and affect the native species.

The exampe of nonnative species is introduction of water hyacinths from Asia in the United States which is affecting the native species and making the ecosystem crowdy.

Introduction of non-native species can disturb the balance of an already-established ecosystem by the native species including plants and animals.

Hence, the correct option is D.

Answer:

Cryptosporidium parvum is an apicomplexan pathogen that obtains glucose either directly from its host or by the degradation of polysaccharides.

Explanation:

C. parvum only can produce ATP by glycolysis. Lactate dehydrogenase (LDH) is a universal enzyme required to synthesize pyruvate, which is the final product of the glycolysis process. This enzyme has been subject of research to understand the metabolism and evolution of apicomplexan parasites, including C. parvum.

Cryptosporidium parvum is a pathogenic agent that causes the disease cryptosporidiosis. The pathogen obtains glucose directly from the host. It can also obtain by the breakdown of polysaccharides.

C. parvum produces ATP through glycolysis. The enzyme lactate dehydrogenase is used by the C. parvum to generate metabolic ATP. It generates this ATP through the glycolytic pathway. The enzyme allows the conversion of NADH to NAD+. NAD+ is necessary for glycolysis to produce ATP. Metabolic energy plays a crucial role in the growth and proliferation of the pathogen in the host.

Some of the features of C. parvum are:

Therefore, C. parvum consists of enzyme lactate dehydrogenase that helps in energy production through the glycolytic pathway.

Answer:

I will go with sponges :)

Sponges reproduce asexually. The parent begins budding, when the buds grow to a certain point, they break off and drift with the oceans current to a new place, settle down into the sand or rocks, and start the cycle all over again. Since sponges are stationary organisms (meaning that they cannot travel on their own.) They rely on the oceans current to spread their species across the oceans.

Answer:

I would do a Moon Jellyfish

Explanation:

Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower. The polyp essentially clones itself. The clone buds out of the original polyp and detaches to float freely in the water.

To preserve Zoological garden expertise are needed to manage the creatures that are there.

Good and conducive environment should be provided for the animals.

Routine cleaning to avoid outback of diseases

Adequate resources should be provided this include food to avoid eviction of important species.

Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.

Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide

Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.

Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.

Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.
