Select all that apply.Which of the following animals filter feeds?

dolphins
fish
baleen whales
clams
sponges

Answers

Animals that filter feeds are called filter feeder. These are a sub-group of feeding animals that eat by filtering the food from water. They use a specialized filtering system from their body to filter their food. Filter feeders are important in cleaning the water. Examples of these are baleen whales, clams, sponges and some fishes. Thus, all are animals which filter feeds except dolphins.

Human impact on the environment can be seen in the deterioration of the alps. a. True

b. False

Answers

Answer:

True.

Explanation:

Environmental impacts can be defined as changes in the environment caused by man and his activities. In the case of the deterioration of the Alps, the constant degradation of nature caused by industrial processes has caused an increase in global temperature, causing the melting of glaciers and degrading the Alps.

Any activity that man performs in the environment will have an environmental impact. This impact, however, can be positive or not. Unfortunately, in most cases, the impacts are negative, leading to degradation and pollution of the environment.

The negative impacts on the environment are directly related to the growing increase in urban areas, the increase in automotive vehicles, the irresponsible use of resources, the excessive consumption of material goods and the constant production of waste. We realize, therefore, that not only large companies affect the environment, we, with small attitudes, cause environmental impacts on a daily basis.

Answer is true!!

Which non-specific defense mechanism is mismatched with its associated body structure or body fluid?

Answers

Answer:

Mucociliary escalator- intestine

Explanation:

This is a complete mismatched. Simply because this defense mechanism maintains the respiratory tract by sweeping foreign substances inhaled with air molecules upwards in the trachea, to be swallowed or spit out .

It is composed of the Goblet cells and Ciliated Epithelium.It is a defence mechanism which protects the lungs parenchyma from infection and inflammation from foreign particles and microorganism. The mucus produced from the Goblet cells trapped theses particles,at the same time moistening the pathways, while the cilliated epithelium beat in upward fashion to sweep them out through the trachea. To complete mucociliary clearance.

The virus that causes mumps in humans is composed of a protein outer shell containing a core of DNA. The virus that causes the flu in humans is composed of a protein outer shell containing a core of RNA. Vaccines that are effective against mumps work efficiently year after year. Vaccines that work against the flu must be revised and changed every year. What accounts for the difference in the effectiveness of these two vaccines?

Answers

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.

DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
