The cell membrane is made up of many different kinds of proteins. These proteins can be classified as either peripheral, transme
joja [24]

Answer: Cell membrane has many properties which is stated below.

Explanation:

The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.

The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.

It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Gnom [1K]

Answer:

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.

Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

Crawfish are shelled organisms that live in shallow freshwater rivers. They can have antennae of different lengths. Two parents
vredina [299]

The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.

The gene determines the amount of protein to be present in the antenna to determine its length.

Explanation:

Data given:

Two crawfish parent = medium length antennae, genotyoe Ll

One offspring = short antenna, genotype ll

one offspring = long antennae, genotype LL

The traits in offspring is shown as:

       L    l

L   LL    Ll

l   Ll     ll

The proportion of allele present in the gene determined the length of the antenna in crawfish.

The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
