Answer:D warm water and low salt content

Explananation

i took the testr

The oceanic water is salty as they have salts mixed in it.

The correct option is C.

70% of the earth is made up of water and most of the water is salty due to the leaching process of salt during the formation of the earth.

In that time rain pours on earth for millions of years which digested the rock and dissolves its nutrient.

Hence, the correct option is C that is warm water with high salt content. The salt concentration remains the same throughout the water.

Answer:

The difference between a stimulus and a response is that a change in the environment is the stimulus; the reaction of the organism to it is the response.

Answer:

║∦║Hello Friend║∦║

Answer:

Sporophytes were branched before the evolution of vascular tissues

In early land plants the gametophytes were branched and complex like the sporophytes

Explanation:

The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).

Answer:

sinusitis

Explanation:

Sinusitis is defined as the swelling or inflammation of the linings of the tissue of sinuses. It is a condition where the cavities where the nasal cavities swells up.

The healthy nasal cavity or sinuses are always filled with air. But sometimes they get blocked and then they are filled with a fluid where bacteria germs grow and causes infection. This causes swelling up of sinuses cavities and a lot of pain is experienced by the person.

Other symptoms are runny nose, headache, nasal congestion and facial pain.

The basic process of disease transmission involves:_________

a. a source, a mode of transmission, and a susceptible host.

Explanation:

The sources of a disease include individuals, animals, and the environment.  Transmission occurs when there is a transfer of the pathogen from one individual or source to another.  Disease transmission cannot be complete without the host.  As always, a successful transmission happens when the host becomes susceptible to the disease, which will weaken its immune system.

Explanation:

Answer:

However, a lot of gene regulation occurs at the level of transcription. Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA. Often, these molecules act by binding to DNA near the gene and helping or blocking the transcription enzyme, RNA polymerase.

Explanation:

Plz mark brainliest thanks

Controlling transcription effect prokaryotic gene expression as when the resulting protein is no longer needed, transcription stops.

Transcription is the primary control point for prokaryotic gene expression. At the levels of epigenetics, transcription, post-transcription, translation, and post-translation, eukaryotic gene expression is regulated.

Due to the lack of a clearly defined nucleus, prokaryotic gene expression takes place within the cytoplasm of a cell; as a result, the DN is freely located within the cytoplasm. Eukaryotic genes are expressed in the cytoplasm and nucleus, respectively.

These molecules frequently work by attaching to DNA close to the gene and assisting or inhibiting the RNA polymerase transcription enzyme.

Therefore, specific regulatory molecules in bacteria determine whether a given gene is translated into mRNA.

Explanation: The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.

The air in the atmosphere becomes thinner and thinner until it fades into the space because thermosphere has less air pressure and gases.

A layer (or layers) of gases that surround a planet and are held in place by the gravity of the planetary body is known as an atmosphere.

The air at the bottom of the atmosphere is under much more weight than the air nearer the top, like the acrobat at the bottom of a stack of acrobats. It follows that the air closer to the Earth's surface is compressed by the air above it and is subsequently denser. The air gets thinner as you go higher in the atmosphere.

Therefore, as we go further into the space the thermosphere becomes thinner and thinner until it fades into space.

Answer:

a. habitat isolation

Explanation:

Habitat isolation is a type of prezygotic reproductive barrier caused by differential habitat preferences, thereby lowering the probabilities of mating between individuals living in different habitats. Habitat isolation is a mechanism of ecological speciation that over time leads to divergence of populations and reproductive isolation. In habitat isolation, different species or populations that could interbreed with one another to produce offspring are prevented from mating as a consequence to be isolated by habitat barriers. In India, for example, lions and tigers can mate to produce offspring; however, they don't interbreed due to habitat barriers (tigers are found primarily in rainforests and lions inhabit the grasslands).

Explanation:

Mitosis is a process of cell division, whereby a single cell divides into two genetically identical daughter cells. The five stage of mitosis are interphase, prophase, metaphase, anaphase and telophase.

1. Interphase:

The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.

Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.

During interphase, microtubules extend from these centrosomes.

2. Prophase:

The chromosomes condense into X-shaped structures that can be easily seen under a microscope.

Each chromosome is composed of two sister chromatids, containing identical genetic information.

The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.

At the end of prophase the membrane around the nucleus in the cell dissolves away releasing the chromosomes.

The mitotic spindle, consisting of the microtubules and other proteins, extends across the cell between the centrioles as they move to opposite poles of the cell.

3. Metaphase:

The chromosomes line up neatly end-to-end along the centre (equator) of the cell.

The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.

The mitotic spindle fibres attach to each of the sister chromatids.

4. Anaphase:

The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.

5. Telophase:

At each pole of the cell a full set of chromosomes gather together.

A membrane forms around each set of chromosomes to create two new nuclei.

The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

Answer: Layers of the Epidermis. The epidermis is the outermost layer of our skin. It is the layer we see with our eyes. It contains no blood supply of its own—which is why you can shave your skin and not cause any bleeding despite losing many cells in the process.

Answer: Metamorphic

Explanation:

which means a change in form. The original rock is subjected to heat and pressure, causing profound physical or chemical change. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism.
