Answer:

The correct answer is - drying the grains in sunlight to remove or reduce moisture.

Explanation:

In agriculture storing the crops and storing the grains of these crops are essential to maintain their germination quality, time, and other factors such as storing for a long time.

In order to store the food grains that are obtained by the crops, farmers should dry the grains in the sunshine before storing them to reduce their moisture content. Reducing the moisture content in grains before storing is essential as moisture increases the growth of fungus and that leads to spoilage of the grains.

C. The particles that make up the aluminium bar are moving faster.

Explanation:

You can notice how you rub your hands outside during winter, right? It gets warmer the more you rub your hands, so it is basically like that, but with the particles of the aluminium bar.

The particles that make up the aluminum bar are moving faster.

It takes greater energy to elevate the temperature of aluminum by 1°C than it takes to raise the temperature of gold by 1°C. Gold's temperature will grow extra and it'll have a higher final temperature and could experience hotter to touch.

Every steel and each fabric has a different rate of heating. here we see that gold heats up 7 times faster than aluminum. This means that the whole lot has its very own specific warmth (also known as warmness capability). Aluminum's precise warmth is zero.216 cal/g·°C, which is set 7 times extra than that of gold (0.031 cal/g·°C).

The difference between speed and velocity is that velocity includes A) direction

The main difference between speed and velocity is that velocity includes direction. Speed refers to how fast an object is moving, measured as the rate of change of distance traveled over time. It is a scalar quantity that only considers magnitude.

On the other hand, velocity is a vector quantity that not only considers the magnitude (speed) but also the direction of motion. Velocity provides information about both the speed and the direction of an object's movement. It indicates the rate of change of displacement over time.

Answer: Age 5.

Explanation: Incredibly, it doubles in size in the first year. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5. The brain is the command center of the human body.

According to neuroscience, the human brain reaches 90 percent of its adult weight at around the age of six years.

Although the brain remains to grow for several years, the vast majority of its growth occurs in the first few years of life. The growth of the brain takes place more in terms of development than in size. The increase in brain size in the early years of life is mostly because of the growth of neural connections. A child's brain continues to develop and grow over time and adolescence, however, the pace of growth decreases with age as the number of neural connections reduces.

In the first two years of life, the brain doubles in size and continues to grow rapidly until about the age of six years. The brain reaches almost its full adult size by the time a person is six years old. However, the neural connections in the brain continue to develop throughout life as the brain experiences new things and learns new skills. Thus, the human brain never stops changing, and it is capable of growing and adapting throughout the individual's lifespan.

Anaxonic neurons are found in the brain and some sensory organs, and their functions include local processing and integration of signals within a small region. Microglia are a type of glial cell that play a crucial role in maintaining the health of the nervous system by monitoring the environment for potential threats, such as pathogens and damaged cells.

They act as the primary immune cells in the central nervous system and perform phagocytosis to remove pathogens and cellular debris, thus helping to maintain a healthy neural environment.

In the field of biology, mucosal cells can be described as cells that make up the lining of various organs of the body. They separate various body cavities from the exterior.

The mucosal cells of the lumen are actively involved in the secretion of mucus. This mucus helps in providing lubrication to food as well as protects the lumen from invading pathogens.

This separation means that each of the daughter cells that results from meiosis I will have half the number of chromosomes of the original parent cell after interphase.

Also, the sister chromatids in each chromosome still remain connected. Chromosomes have been known to travel to the cell's opposing poles during anaphase 1.

This happens from the microtubule network imploding, which decreases the microtubule strands and allows the chromosomes to consolidate at the magnetic sides.

Anaphase A is the first component of anaphase 1, that occurs when the microtubule - connected filaments constrict and shorten. As a result, kinetochores travel in any of 2 ways: up or down.

The chromosomes move in the opposite direction from the kinetochores despite face the pole through this whole process. The third stage of meiosis in one is anaphase 1, whereas the third phase in another is anaphase 2.

With the assistance of centrosomes linked to the nucleus by cytoskeleton, a single pair of paired pairs, which forms a bivalent, is pushed toward the opposite poles of the cell throughout anaphase 1.

The centromere does not split in anaphase 1. It remains unchanged as a whole instead. This is so that the complete chromosome would travel to the polar poles, when in anaphase 2, both homologous chromosomes' centromeres split.

By combining the possibilities for each trait, we can determine the gamete possibilities for this plant. In this case, the gametes would be:

To determine the gamete possibilities for a pea plant with the genotype TtAa, we need to consider the different combinations of alleles that can be passed on during gamete formation. In this case, the genotype TtAa indicates that the plant is heterozygous for two traits: tallness (Tt) and axial flowers (Aa).

During gamete formation, the alleles segregate, and each gamete receives one allele from each gene. The possible gametes for this plant can be determined by separating the alleles and considering all possible combinations.

For the trait of tallness (Tt), the plant can produce two types of gametes: one carrying the dominant allele (T) and one carrying the recessive allele (t).

For the trait of axial flowers (Aa), the plant can also produce two types of gametes: one carrying the dominant allele (A) and one carrying the recessive allele (a).

(B)  A suspect's mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene

Explanation:

I got it right lol and have a good day <3

Option B A suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene is correct.

Mitochondrial DNA (mtDNA) typing is used in forensic science to analyze DNA evidence in cases where the DNA material is degraded or present in small amounts, such as in hair shafts, bones, and teeth.

mtDNA typing is also useful in cases where a person's nuclear DNA (which is unique to each individual) is not available or is contaminated with DNA from multiple sources.

mtDNA is inherited maternally and is present in multiple copies in each cell, making it more abundant and resistant to degradation than nuclear DNA.

Forensic scientists can compare the mtDNA profile of a suspect with mtDNA evidence found at a crime scene to determine whether the suspect's DNA could have contributed to the evidence.

Since mtDNA is not unique to each individual and is shared among maternal relatives, mtDNA evidence alone cannot definitively identify a suspect, but it can help exclude individuals who do not share a common mtDNA profile with the evidence.

Hence option B is correct.
