The thing which is green when you see it in the morning, black if you see it at noon, blue if you see it in the evening, and white if you see it at night is algae.
To be precise, this refers to blue-green algae, which are known to change color depending on the period of the day. These types of algae are known as cyanobacteria, and they can be harmful to the water they are found in, as well as to living beings.

Answer and Explantion

Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.

Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.

Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.

Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.

If a population is steady at its carrying capacity, but then a group of organisms from that species moves in to the same space o

baherus [9]

Answer:

It will remain relatively stable

Explanation:

The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has.

Below the carrying capacity, the population of a species still has the potential to increase due to resource availability, and above the carrying capacity, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.

Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level.

Choose the CORRECT statement concerning the cell membrane lipid molecules

VashaNatasha [74]

Answer:

The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)

Explanation:

Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.

Lipids can easily change places with other neighbor lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.
