Answer:
The correct answer is: marking or tagging pathogens so phagocytes can find and ingest them.
Explanation:
Opsonins are proteins of great importance in our immune system that can intervene in the innate and the adaptative immune response thanks to the complement system.
Opsonins can recognize pathogens or diseased cells and bind to their surface molecules, thus marking them for other cells (particularly phagocytes such as macrophages and neutrophils) to phagocyte (eat) them. This process is hugely important in removing potential threats and non-functioning cells.
Which of the following statements is false?
a. Performing a cross to produce an F1 generation can be used to show if an allele is dominant.
b. The F1 generation is always hybrids.
c. An F1 cross produces an F2 generation.
d. All of the offspring of a cross may exhibit the same trait.
Answer:
d
Explanation:
cannot be same if they produce f2 will take time to be the same!
Thank you!
The correct answer is d. All of the offspring of a cross may exhibit the same trait as it is only in purebred.
The phenomenon of dominant phenotypes springing up from the allele interactions exhibited on this go is called the precept of uniformity, which states that every one of the offspring from ago in which the mother and father fluctuate through best one trait will seem identical.
What are Inherited traits?Inherited traits tendencies encompass matters along with hair color, eye color, muscle structure, bone structure, or even functions just like the form of a nose. Inheritable tendencies are tendencies that get exceeded down from era to the subsequent era. This would possibly encompass such things as passing pink hair down in a family.
Thus it is clear that All of the offspring of a cross may exhibit the same trait is false.

Give differents between lytic and lysogenic cycles
Answer:
the spread of the viral DNA
Explanation:
The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.

why is using dendroclimatology not always a true measure of the past climate
Answer:
Because,There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited.
Explanation:
Along with the advantages of dendroclimatology are some limitations: confounding factors, geographic coverage, annular resolution, and collection difficulties. The field has developed various methods to partially adjust for these challenges.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

Which process produces four genetically different gamete cells?
A. Mitosis
B. Meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Answer:
B. Meiosis
Explanation:
Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes
Answer:
Chromosomes form is DNA in during mitosis.
Explanation:
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.
During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.

Samuel has a block of modeling clay, three heavy blocks, and a hot plate covered by a tray as shown. How could he use these items to model the process of an existing rock becoming a metamorphic rock, according to the rock cycle, and to model the flow of energy that drives this process?
Answer:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray.
Explanation:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray is used for forming a metamorphic rock. Metamorphic rocks are formed when the rocks are placed to high heat, high pressure, hot mineral-rich fluids or combination of all these three factors. Conditions like these are found deep within the Earth so by placing block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray formed metamorphic rock.
¿Qué tipo de célula apareció primero en la Tierra?:___, y se presentan en seres vivos como las:___ y se caracterizan porque:___. *
Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
