Answer:
B: It produces antibodies specific to an antigen.
Explanation:
B lymphocytes (aka B-cells) are lymphocyte white blood cells. They release antibodies that are specifically made for each pathogen and attach themselves onto invading cells and flag it as a harmful cell so that T-cells can come and dispose of it.
If i'm wrong let me know. Hope this helps tho. :D
Answer:
Antigens cause the production of antibodies, and antibodies attack antigens. (D)
Explanation:
From some online research,
1)An antibody is specifically produced in response to an antigen. (Taken from Quizlet)
2)Antibodies bound to antigens on a pathogen's membrane may activate complement proteins to form a membrane attack complex (Taken from a Quizziz)
3)Antigens trigger your immune system to launch an antibody response. This means each antibody wages war against one target antigen. Once antibodies detect antigens, they bind and neutralize them. (Taken from Healthline)
Basically, this means antibodies are formed whenever antigens exist to counter-act it.

Given Proposition: The Shark Population has increased. This is assuming that we only base it off of the given food tree, rather than using the food web, which is more factually correct. This means that the sharks in the area can only eat sea otters, and that sea star populations and sea otters can only eat clams.
1) In this case, the shark population increases. This generally means that the sea otter population by itself has increased, suggesting a positive net change within the given food chain. However, with increased shark populations, would mean a damage to the amount of sea otters in the area. This can create an underpopulation of sea otters, which, if sea stars were not a factor, can mean a increase of clam population.
However.
2) Sea stars are a part of the food chain given. Therefore, it can be suggested that while the sea otter population may stabilize and/or diminish, the sea star has no "predator". This means that with the decrease of the sea otter population, the sea star population may actually grow, as the competition for the same source diminishes. Again, with the demand taking over the need, the sea star population may fall once again due to overfeeding, and essentially starvation.
In essence:
Shark Population: Increased
Sea Otter Population: Decreases (is eaten)
Therefore, Clam Population is speculated to increase.
However, the Sea star population would thereby increase due to having more food.
A larger sea star population in which the clam population cannot sustain would collapse, leading to a fall.
Also, due to the smaller amounts of sea otters in the area, the shark population may also see to an decrease of population, as they die from starvation.
The sea otter population would then stabilize when the predatory amounts or less, and their competition collapses.
Of course, there will always be a "food web". Sea otters do not solely rely on clams, neither do sharks solely rely on otters.

Which of the following is an example of how plankton are beneficial to humans?(diagram is linked) (multiple choice)
A. Plankton are a food source for humans
B. Plankton provide food for fish which humans can eat
C. Plankton are parasites that take out unwanted bacteria
Answer:
B. Plankton are a food source for humans
Plankton is food for many small fish. With the abundance
of Plankton, these fish can thrive. When these smaller fish thrive they are food to bigger fish that we eat. Since the smaller fish thrive then the bigger fish that we eat also thrive. This makes bigger fish an abundant food source due to plankton supporting the smaller fish and other organisms.

Could a man with Type O be the father of a Type AB child? Explain.
Answer:
Yes, I think so
Explanation:
I think yes because if the father has Type O but the mother has Type AB then, I suppose yes. However the alleles would be ABO...I'm not very sure.
"How are ABO alleles inherited by our children? Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter."

Meiosis is a life process associated with sexual reproduction which choice correctly summarizes meiosis into one statement?
SC 912. L. 16.17
O Haploid cells join and produce diploid daughter cells
Chromosomes in a haploid cell are pulled apart, creating two haploid daughter cells
Chromosomes in a diploid cell uncoil and line up, creating two diploid daughter cells.
O Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells
Answer:
Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells
Explanation:
Meiosis is a process in sexual reproduction in which one cell divides twice to form four daughter cells.
Meiosis is a cell division of germ cells that produces sperm or egg cells in male and female respectively. Meiosis undergoes two stages of cell division and finally produces four daughters cells. Each daughter cell in meiosis is haploid and not diploid as it carry half of the chromosomes of its parent chromosomes. Thus, diploid cell separate into 4 haploid daughters in meiosis.
So, the correct choice to summarize meiosis is "Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells".

What is the effect when one part of a system changes?
Answer:
The entire system changes or could stop working.
Explanation:
When one part of the system changes, it may affect the entire system with a systematic consequence of the effective operation of the system.
What is a System?A system may be defined as the arrangement of things or objects that are gathered together and working as parts of a mechanism or an interconnecting network.
When any alteration will be made at any part of the system, it may affect the working of the whole system with respect to the type of alteration made.
Sometimes, this alteration is also responsible for the termination of the entire system.
Therefore, it is well described above.

Explanation:
how does a mitochondrial facilitate the movement of some materials between cells?
Answer:
The key function of the mitochondria is to supply energy by the mechanism of aerobic respiration for cellular activity. Glucose is converted in the cytoplasm of the cell in this step to form pyruvic acid, which is transferred into the mitochondrion.
Explanation:
Like other organelles, by means of organelle-specific adaptors, mitochondria are linked to specific motor isoforms and their movement is vulnerable to degradation of these motors and adaptor proteins.

What is parent material?
Answer:
Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode by which the materials were most recently transported.
What is the relationship between Hox genes and embryological development?
Answer:
Hox genes control the timing of development and growth of embryos. Organisms A and B have very similar Hox genes, and their embryos, in the earliest stages of development, are also very similar.
Explanation:
Hox genes are a family of transcription factors that play a critical role in the development of the body plan during embryogenesis by controlling the spatial patterning of the developing embryo.
What are hox genes?Hox genes play a critical role in embryological development by controlling the formation and patterning of the body segments in animals. These genes are responsible for specifying the identity of different regions of the body, such as the head, thorax, and tail, during the early stages of development. They do this by regulating the expression of other genes that control the differentiation and growth of cells in specific regions of the embryo.
Hox genes are arranged in clusters on chromosomes and are activated in a specific order along the anterior-posterior (front-to-back) axis of the developing embryo. This sequential activation pattern helps to establish the body plan and shape of the organism. For example, the Hox genes that are activated in the head region will determine the formation of the head and brain, while those activated in the thorax region will control the formation of the heart and lungs.
