The energy in a sucrose molecule is stored in the bonds between the atoms.
Hope this helps!
The energy stored in the sucrose molecule is stored in the bonds between the atoms.
Option C
Explanation:
During photosynthesis the sugar molecules are synthesized with help of captured light energy. The bonds between the carbon atoms of sucrose molecule are the covalent bonds and during their breakdown they produces reduced co-factors like NAD and FAD into NADH and FADH2. These reduced cofactors transfer their electrons into electron transport chain which later help ATP synthase to catalyse the production of ATP. Hence the bonds which were made by utilising the photon energy of sun are responsible for the production of energy molecule ATP so the energy is stored in the the bonds between the atoms of sucrose molecule.

Scientific research about the nitrogen cycle and water quality is most
valuable to human populations with:
A
few sources of electricity.
B. few sources of fresh water.
C. large coastal populations.
D. large amounts of farmland.
Answers
Scientific research on the nitrogen cycle and water quality is most valuable to human populations with large coastal populations, as they heavily rely on coastal resources for various purposes. The correct option is C.
Large coastal populations are particularly dependent on the health of marine ecosystems, including water quality. The nitrogen cycle plays a crucial role in maintaining water quality, especially in coastal areas where nitrogen runoff from agricultural activities, sewage discharge, and atmospheric deposition can significantly impact marine environments.
Excessive nitrogen inputs into coastal waters can lead to harmful algal blooms, hypoxia (low oxygen levels), and eutrophication, all of which can have detrimental effects on marine biodiversity, fisheries, and human health. Research on the nitrogen cycle helps to understand the sources, pathways, and impacts of nitrogen pollution, allowing for the development of effective management strategies to mitigate its adverse effects.
Furthermore, large coastal populations often rely heavily on coastal resources for drinking water, recreation, tourism, and economic activities such as fishing and aquaculture. Therefore, maintaining water quality in coastal areas is essential for safeguarding public health, sustaining livelihoods, and preserving the overall well-being of coastal communities.
In conclusion, scientific research on the nitrogen cycle and water quality is most valuable to human populations with large coastal populations due to the significant ecological, economic, and societal implications of nitrogen pollution in coastal environments.
Scientific research on the nitrogen cycle and water quality is most valuable to human populations with:
C. large coastal populations.

In what type of cell must a mutation occur for it to be passed to offspring
Answers
Answer:
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. A single germ line mutation can have a range of effects: No change occurs in phenotype.
Explanation:
A mutation must occur in a germ cell, or gamete, for it to be passed to offspring. This type of mutation is known as a germline mutation, and it can be inherited, affecting every cell of the offspring.
For a mutation to be passed to offspring, it must occur in a germ cell, also known as a gamete. These germline mutations are present in the sperm or egg cells and can be transmitted to future generations. When such a mutation occurs, it can result in every cell of the offspring containing that mutation, as the mutation will be present from the initial zygote stage and is replicated during every cell division. Somatic mutations, in contrast, occur in the non-reproductive cells of the body and are confined to the individual in which the mutation occurs; they cannot be passed on to offspring.

Option C, from the bottom of the meniscus
Explanation:
The meniscus in a graduated cylinder represents the volume of the liquid being measured
The prime aim is to take the reading at the center of the meniscus whether it takes concave shape or convex shape
In case of water, the reading is taken from the bottom of the meniscus and in case of mercury the reading is taken from the top of the meniscus.
However, except mercury in most of the cases the reading is taken from the bottom of the meniscus. Hence, option C is correct

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
A. All children born in future generations will be affected by this disorder.
B. This gene mutation is a dominant disorder.
C. This gene mutation is a recessive disorder.
D. The generation I mother is a carrier of this gene mutation.
Answers
Answer:
B. This gene mutation is a dominant disorder.
Explanation:
Since all the children in generation III do not have the disorder, there is no indication that all the children born in the future generations will be affected by this disorder.
The gene mutation appear dominant from the pattern of inheritance. The children in generation II are all affected because there are two dominant alleles for the disorder in the father. Some of the children in generation III do not have the disorder because only one allele is dominant in the mother, hence, the unaffected children inherited the non-dominant allele from the mother.
The gene mutation is not recessive, otherwise, not all the offspring in generation II are supposed to be affected for the disorder.
The mother in generation I cannot be a carrier because the disorder is a dominant one. There can only be heterozygous for a dominant disorder but they are usually phenotypically affected for the disorder.
The correct option is B.
Answer:
B. This gene mutation is a dominant disorder.

➤ Reason[[Im mainly going of the knowledge I already know, I don't know if I'll be wrong about any of this.]]
Electric energy is energy in general, which can totally cause somewhat disturbing vibrations to the surrounding area. Examples of this are thunder, but, the reason this doesn't count as it is actually converting electric energy, into heat energy, into sound energy. The heat warms up the air so fast it creates a wave of pressure, a shock wave, which is powerful enough to rumble into the distance for miles. What would count is electrical energy by itself. Everyone has heard the sound electricity makes when it zaps and buzzes. It can be rather loud to. This is the energy from the electricity causes vibrations, which is sound energy that can be heard by our ears. Electricity can also power things such as speakers which turn electrical pulses into sound that we can hear with our ears, which is kinda amazing. Science is epik.

A hill is made of rock particles of different sizes. Which of these agents of
erosion probably caused the hill to form?
A. Glacialice
B. Waves
C. Wind
D. Flowing water
Answers
Answer: The answer is A. Glacial Ice
Explanation:
Final answer:
Flowing water is the most probable agent of erosion responsible for the formation of a hill made of rock particles of different sizes, due to its capacity for erosion and deposition based on particle size and gravity's role in pulling it downhill.
Explanation:
A hill made of rock particles of different sizes is likely influenced by several agents of erosion. Among the listed options, flowing water is the most probable cause for the formation of such a hill. Flowing water can transport rock particles of various sizes through erosion and deposition processes. As water moves over land, it picks up smaller particles first, leaving behind larger particles which can accumulate to form a hill. Besides, water moving over steeper slopes increases erosion potential, contributing to the shaping of the landscape.
Although other agents like glacial ice, wind, and waves can also cause erosion, they are less likely to be responsible for the formation of a hill comprised of rock particles of mixed sizes. Glacial ice, for instance, typically forms more uniform deposits and has a distinct erosion pattern, including features like U-shaped valleys rather than hills mixed with varying particle sizes.
It is important to note that gravity also plays a role in the process of erosion by pulling water and ice downhill, which in turn shapes the earth's surface. Flowing water also contributes to the formation of distinctive geological features through the differential erosion of rocks with varying levels of erosion resistance.

Answers
Answer:
b
Explanation:
so that the habitat doesnt get overcrowded
The competition increase stability in an ecosystem by keeping population Balanced.
Explanation:
There is increase in competition this will in turn deals with stability in ecosystem. Because this creates continuous food chain where a larger animal will eat the smaller one and this cyclical chain keeps in check. The food chains creates complexities in the biodiversity this again is compensated with increase in population. With a lot more increase in species again the food chain demands the cyclical procedure. This is how in our biodiversity the stability in the organism is maintained.

What are the functions of Uterus?The uterus is an organ of the female reproductive system. It’s shaped like an upside-down pear and has thick walls. The main function of the uterus is to house and nourish a fetus until it’s ready for birth.If conception occurs, the fertilized egg (the embryo) burrows into the endometrium from which the maternal portion of the placenta, the decidua basalis, will develop.As pregnancy progresses, the uterus grows and the muscular walls become thinner, like a balloon being blown up, to accommodate the developing fetus and the protective amniotic fluid produced first by the mother and by the urine and lung secretions of the baby.During pregnancy, the muscular layer of the uterus begins contracting on and off in preparation for childbirth.Hence, option A is the answer.
