Answer:

Explanation:

1. Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.

2. Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

3. Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.

4. Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean

Explain about the temperate forest biome. Explain how the organisms in cold forests biome adapt to their environment. Also expla
antiseptic1488 [7]

Answer:

In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.

Andre45 [30]

Answer:

B) stain only the thicker peptidoglycan cell walls

Explanation:

Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.

He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.

Thus, Option-B is correct.

Refrigerating or freezing foods will kill most or all bacteria present in the food. refrigerating or freezing foods will kill mo
ExtremeBDS [4]

<u>Answer</u>: Option b false

<u>Explanation</u>:

  • Refrigerating or freezing foods <em>does not kill all or most of the bacteria</em> in the food as lowering the temperatures of the food only renders the microbes present in it <em>inactive</em>. As soon as the food is brought back to normal temperature, the microorganisms present in it become active again.
  • The advantage of freezing food is only limited to the fact that once the food is frozen, all the microbes be it fungus, bacteria etc. become inactive and do not multiply and thus, freezing prolongs the shelf life of food, however once this food is thawed the micro organisms again become active  and start multiplying and can easily cause food borne illness.
  • So, the only way to kill the micro organisms present in the food is to cook the food to correct temperatures and not freezing.
