The plant hormone that triggers the withering of petals and stamens and promotes fruit ripening is
A. abscisic acid.
B. cytokinin.
C. gibberellin.
D. auxin.
E. ethylene.
Answers
The plant hormone that triggers the withering of petals and stamens while promoting fruit ripening is ethylene.
Correct option is E.
Abscisic acid is a plant hormone primarily involved in controlling processes such as seed dormancy, leaf abscission, and inhibition of cell division. It is produced in growing leaves and buds and is also found in fruits and seeds, where it performs a ripening and ripening-related functions. When abscisic acid accumulates in the reproductive organs, it causes the petals and stamens to wither and fall off.
It also triggers the ripening of fruits and vegetables by activating specific enzymes in the cells. Abscisic acid is also involved in other important processes like controlling leaf water stress through the stomatal closure and promoting bud dormancy. It primarily works in opposition to auxin, a plant hormone that stimulates fruits and leaf abscission.
Correct option is E.

C. A system that only repairs thymine dimers is _______ .
D. In _______ , the damaged section of one DNA strand is removed and replaced with new DNA that is synthesized using the undamaged strand as a template.
E. Cells can repair damage that produces breaks in DNA using enzymes related to those involved in _______ during meiosis.
Answers
A. Repair systems that target a single type of damage in DNA and repair only that type of damage are called specific repair systems.
B. Repair systems that use a single repair mechanism to repair multiple types of damage in DNA are called nonspecific repair systems.
C. A system that only repairs thymine dimers is photo repair.
D. In excision repair, the damaged section of one DNA strand is removed and replaced with new DNA that is synthesized using the undamaged strand as a template.
E. Cells can repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis.
Specific repair systems target and repair a single type of DNA damage, such as photo repair which repairs only thymine dimers caused by UV light. In contrast, general repair systems use a single mechanism to repair multiple types of DNA damage, such as excision repair which can repair damage caused by chemical exposure and radiation.
Photorepair is a specific repair system that repairs thymine dimers in DNA caused by UV light. The process involves using energy from visible light to break the bonds between the thymine molecules and return them to their normal state. Excision repair is a general repair system that involves removing a damaged section of DNA and synthesizing a new, undamaged strand using the complementary strand as a template.
Cells can also repair the damage that produces breaks in DNA using enzymes related to those involved in recombination during meiosis. This process, known as homologous recombination, involves exchanging genetic material between two homologous chromosomes to repair a break. This mechanism is highly regulated to prevent errors and ensure proper repair of DNA damage.

What are the similarities between solution and substance?A substance and solution are similar to each other in many ways because a solution is a homogeneous blend of two or more elements and/or compounds. Whereas a substance is an element or compound, therefore, a solution is a homogeneous combination of two or more substances.
A substance is different from solution because substance is an element or a compound whereas a solution is made up of combination of two or more substances. In a mixture, substances are generally just mixed and are not completely dissolved. In a solution, substances are dissolved completely and they cannot be filtered out.
So we can conclude that the substance and a solution are different as well similar to each other because the solution is a homogeneous mixture whereas substance is an element or a compound.

a heterozygous dihybrid cross resulted in three possible genotypes. what can be concluded?
Answers
If a heterozygous dihybrid cross resulted in only three possible genotypes, it can be concluded that the two genes are either linked or they are located very close to each other on the same chromosome.
In a typical dihybrid cross, four different phenotypes are expected in a 9:3:3:1 ratio, assuming that the genes assort independently. However, when two genes are linked or located close together, they tend to be inherited together more often than not, resulting in fewer than four possible phenotypes. This phenomenon is known as genetic linkage.
Alternatively, it is possible that there was some sort of genetic mutation or epigenetic change that affected the inheritance of the two genes in question. However, without more information, it is difficult to say for sure what caused the observed outcome.

The examples of plant processes that involve an interaction between stems, roots, and leaves is water is transported up the stem from roots to leaves via the xylem. Hence option A, B an E is correct.
What is homeostasis?Homeostasis is defined as any self-regulating mechanism by which biological systems have a tendency to keep their stability while responding to environmental factors that are best for survival. The preservation of essentially constant internal conditions is referred to as homeostasis.
The xylem carries water up the stem from the roots to the leaves. Water must be absorbed by the root system in order for photosynthesis to occur in the leaves. The phloem circulates glucose produced by photosynthesis in the leaves throughout the plant.
Thus, the examples of plant processes that involve an interaction between stems, roots, and leaves is water is transported up the stem from roots to leaves via the xylem. Hence option A, B an E is correct.

sodium is pumped into the medulla from the thick segment of the loop of henle. if the concentrations of the fluid and medulla are equal, what mechanism would produce the movement of sodium into the medulla?
Answers
The mechanism that would move the sodium into the medulla is an active transport mechanism across the membrane.
Active transport is the term that describes the movement of molecules or ions across a cell membrane against the concentration gradient. It requires cellular energy in the form of ATP to be done.
One case of active transport in the human body is the sodium-potassium pump. It's a mechanism in the form of an enzyme that maintains osmotic equilibrium in cells. One place where it's found is in the kidney around the medulla and the loop of Henle. When the concentration of the fluid and medulla are equal, sodium-potassium transport work to maintain the proper concentration of K+ and Na+ ions inside and outside of the cells.

n most muscles, when a muscle contracts and its fibers shorten, the origin moves toward the insertion. True False
Answers
In most muscles, when a muscle contracts and its fibers shorten, the origin moves towards the insertion. This is true. Muscle contraction is the shortening, tightening and lengthening of muscles due to some physical activity.
During muscle contraction, one end of the muscle moves while the other end is fixed in its position. The point of attachment that moves during any action is called insertion while the point of attachment that doesn't move during action is called origin. The origin has more muscle mass and is less movable whereas the insertion has less muscle mass and is more flexible and movable. Muscle contraction occurs in the following sequence :
formation of cross bridgepower stroke dissociation of cross bridgecocking of myosinThe muscle unites the immobile bone at the origin which is fixed whereas the muscle unites the moving bone at the insertion.

how does sustainable development supports the appropriate use of natural resources and long lasting development?
Answers
Answer:
Sustainable development is the management of renewable resources for the good of the entire human and natural community. The goal of sustainable development is to provide resources for the use of present populations without compromising the availability of those resources for future generations, and without causing environmental damage that challenges the survival of other species and natural ecosystems.
Explanation:
the stocks of non-renewable resources, such as metals, coal, and petroleum, can only be diminished by use. Consequently, sustainable economies cannot be based on the use of non-renewable resources. Ultimately, sustainable economies must be supported by the use of renewable resources such as biological productivity, and solar, wind, geothermal, and biomass energy sources. Central to the notion of sustainable development is the requirement that renewable resources are utilized in ways that do not diminish their capacity for renewal, so that they will always be present to sustain future generations of humans. To be truly sustainable, systems of resource use must not significantly degrade any aspects of environmental quality, including those not assigned value in the marketplace. An ecologically sustainable economy must be capable of supporting viable populations of native species, viable areas of natural ecosystems, and acceptable levels of other environmental qualities that are not conventionally valued as resources for direct use by humans.

Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.
