Answer:
Part D: pilus
Explanation:
Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.
The structure in bacteria that allows them to exchange genetic material and evolve is the pili
Bacteria piliPili (pilus, singular) are thin, proteinous structures located on the surface of bacteria that serves as:
they help bacterial cells to attach to surfacesthey serve as channels for the transfer of genetic materials during conjugationWhen genetic materials are transferred through the pilus, gene recombination occurs and bacteria evolve as a result.

Why is DNA locked in the nucleus of the cell ?
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.

The term used to describe the front of the elbow is
Answer:
Antecubital
Explanation:
In technical anatomical terms, antecubital refers to the area anterior to the elbow—meaning the opposite side. In the human body, the antecubital area is where the humerus (upper arm bone) connects to the radius and ulna bones of the forearm.
The term used to describe the front of the elbow is: Antecubital fossa
Antecubital fossa is the term used to describe the front surface of the elbow. this area is important in the human arm because it is the area where the upper arm bone connects with the bones of the forearm ( ulna and radius ).
The name Antecubital fossa is derived from the Latin name Cubitus
During the insertion of IV into the human body or during blood donation, the Antecubital area is very vital because veins can be easily located around the area than any other part of the body.
Hence in conclusion the term used to describe the front of the elbow is Antecubital.

Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
What is the function of the surface protein on the influenza virus?
A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA
Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.

What is the name for winds that usually blow in the same direction?
Dry winds
Prevailing winds
Smart winds
Strong winds
Answer: (B) Prevailing winds
Explanation: the name for winds that usually blow in the same direction is Prevailing winds
The name for winds that usually blow in the same direction is "Prevailing winds". Therefore, option (B) is correct.
What is prevailing winds?Prevailing winds are the dominant winds that blow consistently over a region, resulting from the combined effects of global atmospheric circulation patterns, the Coriolis effect, and local geography. These winds typically blow from the same direction and have a significant impact on regional climate, as they can bring in moisture, temperature changes, and other weather conditions.
Prevailing winds can be important for agriculture, transportation, and other human activities that are affected by weather patterns. Therefore, option B, prevailing winds, is the correct answer

4. jellyfish
Answer:
2. octopuses
Explanation:
A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus.
Octopuses belongs in class Cepholopoda. So, the correct option is (B).
What is Cephalopod?A cephalopod is defined as any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus where specifically marine animals with bilateral body symmetry, a prominent head, and arms modified from primitive molluscs or is characterized by a set of tangents foot. These animals use gills to breathe and are invertebrates (lack backbones).
Cephalopods are most notable for their many arms and soft bodies, while ancestral cephalopods are known mostly from their shells because they are well preserved as fossils. The octopus, squid, cuttlefish, and chambered nautilus are familiar representatives.
Thus, Octopuses belongs in class Cepholopoda. So, the correct option is (B).

and produces soot. This soot begins to cover the trees. Eventually the trees become darker, see the picture on the right. Use the data below to explain what
happened
Answer:
This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.

Velocity is The amount of time it takes an object to move from point A to point B. Therefore, option B is correct.
What is velocity?When an item is moving, its velocity is the rate at which it is changing position as seen from a particular point of view and as measured by a certain unit of time. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed). The various forms of velocities include uniform, variable, average, and instantaneous velocities.
There are countless practical uses for velocity, but one of the more frequent ones is figuring out how quickly you (or anything in motion) will get somewhere from somewhere.

Answer:
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. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.
