Answer: Chemical energy
Explanation: During light dependent reactions of photosynthesis, light is absorbed by chlorophyll and other light absorbing pigments. The light energy absorbed is conserved as ATP and NADPH. In light dependent reactions, the light energy is used to split water molecules into hydrogen ions and oxygen molecules and consequent production of ATP and NADPH. This reaction is called photolysis of water. The oxygen molecules is evolved while the hydrogen ions are transferred to NADP+ to produce NADPH. In light dependent reactions, ATP and NADPH are produced.
ATP and NADPH are forms of chemical energy which are usable in the cells. Therefore, light energy is converted into chemical energy in light dependent reactions of photosynthesis.
Which of the following would be a body response when stepping outside without a coat on a snowy day?
On a snowy day, without a coat, our body responds in three ways. It gives goosebumps to trap heat, induce shivering to generate heat, and constricts blood vessels to preserve body heat.
Explanation:When stepping outside on a snowy day without a coat, our bodies respond to the freezing temperatures in several ways. First, you'll likely experience goosebumps, a reflex action aimed at raising body hair to trap warm air closer to the skin. Second, you might also begin to shiver, a rapid contraction and expansion of muscles to generate heat in your body. Third, blood vessels near the skin will constrict (vasoconstriction) to preserve body heat, diverting it towards vital organs.

The body response to cold when stepping outside without a coat includes narrowing and contracting blood vessels in the skin (vasoconstriction) to reduce heat loss and maintain core body temperature.
When stepping outside without a coat on a snowy day, the body responds by initiating thermoregulation to preserve heat. The correct response is A. Blood vessels in the skin narrow and contract, a process known as vasoconstriction. This action reduces the flow of blood to the skin's surface, thereby minimizing heat loss. In contrast, during activities that increase body temperature such as running or skiing, the body would dilate the dermal blood vessels and increase sweat secretion to prevent overheating, but this is not the case in cold environments. Instead, the body conserves heat to maintain core temperature.
The complete question is:
Which of the following would be a body response when stepping outside without a coat on a snowy day?
A. Blood vessels in the skin narrow and contract.
B. More liquid is transported by the body to the skin for insulation.
C. Sebaceous glands secrete more sebum.
D. Blood vessels in the skin expand
Why is open pit mining so devastating to the environment?
Answer:
A. It completely removes any available topsoil.
Explanation:
Open pit mining is damaging to the environment because it entails the removal of topsoil and subsoil that house important organisms, it leads to water contamination due to discharge of harmful chemicals from processed minerals, and triggers deforestation, which affects biodiversity and contributes to carbon release.
Explanation:Open pit mining, also known as strip-mining or mountaintop mining, is incredibly devastating to the environment. There are several reasons for this.
Firstly, the process involves the removal of large quantities of topsoil and subsoil. These layers are home to many organisms that form a crucial part of the ecosystem, and their removal can disrupt this fragile balance.
Also, open pit mining often leads to water pollution. The extracted minerals are usually processed with water, which can then discharge harmful chemicals into nearby streams and groundwater. This is termed water contamination, and it can affect animal, plant, and human life.
Finally, open pit mining leads to deforestation. To make room for the mines, large areas of forest must be cut down, which results in loss of habitat for many species and a significant release of carbon dioxide into the atmosphere.

Explanation:
Blood type in humans is an example of a trait that has multiple alleles. The alleles for type A blood and type B blood are codominant, and type O blood is recessive to both type A and type B. If a girl with type AB blood has a brother with type O blood and a sister with type B blood, which of the following genotypes could it be possible for their parents to have?
Given that the offspring have blood types AB, B, and O, it is possible for the parents to have genotypes of IAi and IBi. This demonstrates the facets of multiple alleles and codominance in the determination of blood types in humans.
Explanation:The possible genotypes for the parents are IAi and IBi. The girl with blood type AB must inherit an A allele from one parent and a B allele from the other, making her genotype IAIB. The sister with blood type B could have inherited an B allele from either parent and an i allele from the other, making her genotype IBi. The brother with blood type O inherited an i allele from each parent, making his genotype ii. Therefore, the parents' possible genotypes could be IAi and IBi.
As background, the ABO blood groups are determined by three alleles. The IA and IB alleles are codominant, meaning that when present simultaneously, both are expressed, leading to the type AB blood group. The i allele is recessive to both the IA and IB alleles, and in the absence of either of these, the O blood type results.

Natural selection is the idea that species change over time, and evolution is the idea that our world changes over time. C. Natural selection is the idea that species change over time, and evolution is the idea that the species' food source also changes over time. D. Evolution is the idea that species change over time, and natural selection is the idea that nature changes over time.
The correct answer is A
Answer:
The correct answer will be option A.
Explanation:
Evolution is a process which changes the characteristics of a species over several generations which changes species over time.
Natural selection is one of the mechanism by which species become adapted to their environment and evolve over time.
Natural selection takes place at the genetic level as the genetic mutations beneficial to survival are passed on to next generations through reproduction which result in generation of new organisms.This causes species to change and diverge over time.

the fossil record shows that an organism is relatively unchanged for a long period of time, followed by several changes over a short period of time, followed by another period of stability. this provides evidence for which view of evolution?
A. biotic potential
B. monophyletic development
C. graduated speciation
D. punctuated equilibrium
Answer:
D. punctuated equilibrium
Explanation:
Punctuated equilibrium refers to the process of evolution which includes two long periods of little or no change in the gene pool of population. These periods of stability are disturbed by a short active phase of rapid changes in the gene pool and appearance of adaptations in individuals of population. Hence, the organism showing two prolonged periods of stability in terms of evolution punctuated by short phase of changes represents punctuated equilibrium.
Answer:
The correct answer is option D. "punctuated equilibrium".
Explanation:
Punctuated equilibrium is an evolutionary theory that states that a species stays in a long period of time without suffering any substancial change called "statis", followed by a short and rare period of dramatic changes called cladogenesis. Punctuated equilibrium states that evolutionary changes occur quickly and in separated periods of time. This theory of evolution contrast the theory of phyletic gradualism, which states that evolution occurs constantly and uniformly by gradual transformations.

12. Plants that we recognize today spend the majority of their life in the
A. seed phase
B. diploid phase
C. gametophyte phase
D. haploid phase
Answer:
B. diploid phase
Explanation:
The plants that we recognize today are most angiosperms and they like all other vascular plants. The dominant phase is the sporophyte generation. Each cell of the sporophyte generation is diploid. Most of the time in the life cycle of a plant is spent in vegetation phase (root, stem and leaf) and reproductive phase (flowers). Flowers produce spores after meiosis. Spores are geminate to form gametophytes which are haploid. Male gametophyte develops within a pollen grain and produces sperm. Female gametophyte develops in the ovary and produces eggs. After pollination and fertilization, a diploid zygote which is the first cell of sporophyte is formed. The zygote develops into an embryo inside a seed.

what phenomenon is responsible for Hotspot volcanism
A. ridge push
B. pyroclastic flows
C. subduction
D. mantle plumes
Answer:
D. mantle plumes
Explanation:
The hotspot volcanism occurs because of mantle plumes. This type of volcanic activity can occur both in oceanic plates, or in continental plates. The mantle plumes are very powerful. They manage to penetrate through the crust without any particular problem, even if it is the the thickest part of the crust. This is why the hot spot volcanism is mostly found in the middle of the tectonic plates, or at least far away from the plate boundaries. The plates move above the mantle plumes, or rather the hotspot, and as they do they drag away with them the volcanoes that have been created. The volcanoes will lose their connection with the hotspot and they will stop being active, but the hotspot will create another, new volcano above, and the process continues. This type of volcanic activity can be seen on the Hawaii Islands, as well as the Yellowstone supervolcano.
Which of these is most likely to cause noise pollution
A - Power plant
B - Rock concert
C - Street lamps
D - Pavement runoff
(APEX) Hellllpppp me:(
Answer: B - Rock concert
Explanation:
Noise pollution can be define as an environmental pollution which is caused by the emission of elevated levels of sound for a considerable long period of time. The elevated level of sound may have an adverse impact over the human and other animal hearing ability. According to world health organization, the sound level beyond 85 db for a period of 8 hours is hazardous.
Among the options given, rock concert is the correct. The rock concert is associated with noise pollution as it will involve the use of loud speakers with high volume which can cause heart problems and hearing impairment.
Among the given options, a Rock concert is most likely to cause noise pollution due to the high levels of sound produced that can impact both human and animal life, unlike street lamps and pavement runoff which relate to other types of pollution.
Explanation:Noise pollution is a significant environmental concern that can arise from various human activities. Among the options provided, B - a Rock concert is most likely to cause noise pollution. This is attributed to the high decibel levels typically associated with concerts, which can include amplified music and large crowds, both contributing to the creation of noise that can disrupt human and animal life. For example, chronic noise pollution from events like concerts can lead animals to abandon habitats, disturb reproductive functions, and increase vulnerability due to impaired hearing. Additionally, regular exposure to loud noise can result in hearing damage in humans.
Other human activities such as operating power tools, listening to MP3 players at full volume, and living near areas with frequent traffic noise can also contribute to noise pollution. These sources can affect children's learning capacities and cause varying levels of stress and discomfort in people. In contrast, street lamps and pavement runoff are not typically associated with noise pollution, but rather with light pollution and water pollution, respectively.
