Your lab group is assigned an unknown organism to identify to the level of phylum. You have it narrowed down to either Phylum Porifera or Phylum Cnidaria. Which feature would allow you to identify the phylum of your unknown creature
Answer:
The correct answer is - the presence of pores.
Explanation:
The name Porifera is a term that means pore bearer as these individuals are one cell thick with many tiny pores present on their body and some big openings as well. These small pores are one of the characteristic features of these organisms. It distinguished the Porifera phylum from the Cnidaria phylum. There are many other microscopic and behavioral features present to classify them but in the lab presence of pores is important.

Which of the following is a potential benefit of a disturbance to a
community?
O a decrease in availability of resources
o the community may be unable to recover
O some species depend on disturbances
O links between the native species break
Answer:
I'm pretty sure it is 'some species depend on disterbences'
The potential benefit of a disturbance to a community is that some species depend on disturbances.
Importance of disturbance in a communityCommunity disturbance can be defined as a force, which may be biological or non biological, that results in mortality of organisms or loss of biomass.
Different types of disturbance that can affect a community include:
fires, storms, diseases, volcanic eruptions, earthquakes, contaminant spills, and land clearing.Some species depends on community disturbance because the cleared habitat caused by the disturbance leads to species movement into the newly cleared area, that is, secondary succession.

A. The DNA in the nucleus would be protected from harmful substances
B. Enzymes would not be able to speed up reactions in the nucleus.
C. The nucleus would not be able to communicate with the rest of the cell.
D. Large molecules would be able to enter and damage the nucleus.
Answer:
D
Explanation:
If the layer of nucleus were permeable to most substance, then the large molecules would be able to enter and damage the nucleus.
What is nucleus?It is a membrane-bound organelle present in the centre of cell in which thread like structures called chromatins are present which condenses to form chromosomes contains genetic material (that carries genetic information from parents to offspring).It controls all function of the cell.The layer or membrane around nucleus is called nuclear membrane is semi-permeable in nature which means that only specific molecules and ions can move across it.If the membrane would become permeable, then movement of all types of molecules will occur which will disturb the homeostasis (maintaining balance) of cell and can damage the nucleus.Hence, the correct option is: D. Large molecules would be able to enter and damage the nucleus.

electrons.
B. Covalent bonds are formed when atoms transfer one or more
protons.
C. Covalent bonds are formed when atoms share one or more
protons.
D. Covalent bonds are formed when atoms transfer one or more
electrons.
Answer:
A
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Answer: The answer is A Covalent bonds are formed when atoms share one or more electrons

Which list identifies the order of events that formed a volcanic crater?
A) CBDA
B) BACD
C) CADB
D) DBAC
Based on the given image, the order of events that formed a volcanic crater is CADB. Thus the correct option is C.
What is a volcanic crater?A nearly circular hole in the ground produced on by volcanic eruptions is known as a volcanic crater. It is a valley that typically stands just above the eruption where volcanic debris is emitted, and it has the shape of a bowl or funnel.
During volcanoes, craters' dimensions and shapes could alter. A volcanic crater, also known as a caldera, is a sizable depression created when a natural disaster occurs and then collapses.
Underneath the surface of the Earth, the molten rock is known as magma. Less dense than normal lava is being pushed upward to the surface by intense pressure. When magma seeps through layers of preexisting rock, it forms another structure.
Therefore, option C is appropriate.
