Janelle thinks that genetic engineering could be used to
make a larger fruit rather than cloning the fruit. Which would best support her point of view? A. Genetic engineering does not cost as much.
B. Genetic engineering does not result in genetically identical organisms. C. Genetically engineered foods never cause allergies in people. D. Genetically engineered foods have not been modified.
Genetic engineering is the process by which scientists choose a particular group of genes and insert them into an organism in such a way that the resulting features will be beneficial to the organism. Therefore, option (B) is correct.
What is genetic engineering?The modification and manipulation of an organism's genes through technology is known as genetic engineering, often referred to as genetic modification or genetic manipulation.
Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA. Therefore, option (B) is correct.

1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older
Answer:
Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.

14. Why doesn't the inner core have convection?
Answer:
The inner core has subsequently been growing at the rate of around 1mm a year as iron crystals freeze and form a solid mass. The heat given off as the core cools flows from the core to the mantle to the Earth's crust through a process known as convection.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

A lake in Minnesota was thriving with black bass and bluegill. These particular fish build nests on the sandy bottom of the lake. Now, ecologists are finding that over time a layer of humus has slowly been covering the pond. The ecologists are noting that the populations of black bass and bluegill are declining, and the fish that are able to make nests in humus are rising in numbers.
The ecologists can probably conclude that this event is an example of:
commensalism
parasitism
primary succession
succession
Answer:
Explanation:
https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession
The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.
Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.
In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.
The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.
The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.
Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

Work
Power
Energy
Answer:
Power
Explanation:
The formula work divided by time is the expression for finding the power consumed or expended by a body.
Power is defined as the rate at which work is done.
Power = [tex]\frac{work done}{time taken}[/tex]
The unit is always expressed in watts and symbolized as W
Work done is force applied to move a body through a certain distance.

The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.
What is Circulatory System?The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.
The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.
Therefore, the correct option is D.
