Answers
Answer:
Below is the numbers that is in the equation of photosynthisis
Explanation:
Answer:
A. Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar.
Explanation:
Photosynthesis is a process through plants synthesize their own food with the help of sunlight. In this process, light energy from sun is converted into chemical energy through a series of reactions which is stored in the form of food.
In the process, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react in the presence of sunlight to produce 1 molecule of glucose sugar. Apart from glucose, 6 molecules of oxygen are also produced during photosynthesis.
A balanced chemical reaction for photosynthesis is as follows :
Sunlight
6CO2 + 6H2O —---------> C6H12O6 + 6O2.
(carbon (water) (glucose) (oxygen)
dioxide)

If you put the 2 rats in different environments, you will not only observe the adaptations they use to survive in different environments, but what consequences will occur if they are in a unfamiliar environment
Answer: C. Put the two groups in different environment.
Explanation:
Speciation is the process in which new species develop from the parent or pre-existing species in due course of evolution. The following are the types of speciation.
1. Allopatric speciation: This results when the two populations of the same species, are separated geographically.
2. Sympatric speciation: This results when the two populations living in the same area diverge due to changes in the behavior, morphology and in genomic level. This results in reproductive isolation among members of the same species belonging to two distinct populations.
Among the options given, C. Put the two groups in different environment. is the correct option. This is because of the fact that this will favor allopatric speciation. As due to geographical barrier, the separated groups will develop traits different from the parent species. Hence, result in development of new species.
Infants and young toddlers find it more difficult to recover from brain damage than adults because their brain has not developed plasticity yet.
Answers
Answer:
False
Explanation:
If it is a T or F questions then yes it is false.
Contrary to the misconception, infants and young children have a high capacity for brain recovery due to neural plasticity, which allows the brain to form new neural connections.
Neural plasticity refers to the brain's ability to reorganize itself by forming new neural connections throughout life. For instance, when an infant suffers damage to the temporal lobe's facial recognition areas, although they may face challenges, the brain's ability to adapt is still significant.
Neuroplasticity continues into adulthood, although its effects may be less pronounced compared to those in children. Adult brains can still rewire to compensate for injury and change in response to experiences, which is evident in cases such as accomplished musicians displaying larger auditory cortexes or requiring less neural activity for finger movements. Despite these adaptive capabilities, some conditions like neurodegenerative diseases do pose much greater challenges and may not show strong evidence of the brain's capacity to recover.

formed where mantle erupts through crust
Answers
Answer:
- formed in the middle of a plate
- formed where mantle erupts through crust
Explanation:
The Hawaii Islands are a chain of volcanic islands. They have been formed by a hot-spot in the middle of an oceanic plate, the Pacific tectonic plate. The convection currents in the mantle are much stronger in this part, and it manages to easily break through the crust. As it does, the magma from the mantle has been rising the seafloor and as it was going up it emerged above the surface of the water, resulting in the formation of volcanic islands. Because the plate is moving over the hot-spot, the volcanoes are moved away and detached from the hot-spot, so they stop being active. The hot-spot though continues to propel magma upwards, so it forms new volcanic island, and the process goes on and on, so a chain of numerous volcanic islands is formed, and maybe a new continent in the future.
Answer:
- formed in the middle of a plate
- formed where mantle erupts through the crust
The amount of radioactive isotopes contributing heat to Earth is greater now than it was when Earth was newly formed.
Question 20 options:
True
False
Answers
Answer:
false
Explanation:
The amount of radioactive isotopes contributing heat to Earth is less now than when Earth was newly formed because these isotopes have decayed over time, making the statement false.
The statement that the amount of radioactive isotopes contributing heat to Earth is greater now than it was when Earth was newly formed is false. Radioactive isotopes such as 238U, 235U, 40K, and 232Th have been providing heat to Earth's interior through radioactive decay. Initially, there were more of these isotopes when Earth was young, making the radioactive contributions and resulting heat greater. These isotopes decay over time, reducing their quantity and the heat they produce. Presently, the heat produced by radioactive decay is roughly 25% of what it was at Earth's formation.
Additionally, Earth's heat also comes from the initial deposit of heat left over from its formation and accretion, with energy contributions from impacts such as the one from Theia, which led to the creation of the Moon. However, it's the radioactive decay of primordial elements that still significantly contributes to Earth's internal heat, albeit less so than when Earth first formed.

A. Limited resources in an environment forces more genetic changes in individuals, allowing the species to evolve more quickly.
B. Limited resources in an environment means that the individuals of a species cooperate so that all individuals survive.
C. Limited resources in an environment forces some individuals to survive without food.
D. Limited resources in an environment means that not all individuals of a species will survive or reproduce at equal rates.
Answers
Answer:
Option (C).
Explanation:
Malthus had stated that the population growth was exponential. He explained the relationship between population growth and resources.
Malthus study on population growth and limited resources on human population has contributed to the Darwin's idea of evolution. Limited resources in a population allows the survival of some individual species only. Natural selection favors the selected population and species adapt in the environment and transfer beneficial allele to its next generation.

What characteristic of radioactive decay makes it useful for determining the absolute age of samples?
Question 10 options:
occurs at a constant rate
changes based on temperature
speeds up under high pressure
slows down in very dense samples
Answers
Answer:
occurs at a constant rate
Answer:
Option A, occurs at a constant rate
Explanation:
It becomes easy to determine the age of any radioactive substance when the rate of decay is constant and its starting and presents mass is known.
For example - if we know that the mass of a radioactive substance is 100 Kg few years back , but its present mass is 10 Kg. Then if we know the value of rate of decay, we can easily determine the age of substance based on the logarithmic equation as given below
[tex]A_t= A_0*e^{kt}[/tex]
Where [tex]A_t[/tex] is the mass of radioactive substance at time t
[tex]A_0[/tex] is the mass of radioactive substance at time [tex]t=0[/tex]
t is the time in years and
k is the decay constant.
Hence, option A is correct.
Plate divergence is best described a/an _______ process.
O A. orogenic
O B. isostatic
O C. taphrogenic
O D. epeirogenic
Answers
Answer:
C. taphrogenic
Explanation:
The plate divergence can be described as a taphrogenic process. The taphrogenic processes are the processes through which gaps occur in the crust, and the crust is moving away from the gap that has opened up. This is exactly how the divergent boundaries form. The strong convection currents of the mantle manage to crack the crust, and the magma manages to penetrate through it and melt it. As the magma reaches the the surface, it starts to come out, propelling itself upward, and as it cools of it creates new crust. The magma continues to come out, and more and more new crust is pilling up, pushing the old crust away from the divergent plate boundary.

Photosynthesis occurs in both prokaryotes and eukaryotes.How do the location where photosynthesis occurs differ in prokaryotes and eukaryotes?
Answers
Answer:
In eukaryotes, it occurs in the chloroplast. In prokaryotes it does it in the cytoplasm.
Explanation:
Prokaryotes don't have organelles such as the mitochondria and the chloroplast, it just has cell membrane, which its only function is to protect the cell and is unable to generate chemical processes; the DNA, which stores and manages only the genes, which would be affected if exposed to a chemical process like photosynthesis; and the cytoplasm, which stores the materials that the cell needs, where photosynthesis occurs. Eukaryotes have chloroplasts, which absorb the sunlight and combine it with carbon dioxide and water to realize photosynthesis.

Answers
Answer:
D. Priming.
Explanation:
Final answer:
The process where hearing the word 'rabbit' influences the spelling of 'hair' as 'hare' is known as semantic priming, a cognitive process where one stimulus affects the response to another.
Explanation:
The scenario described in the question where hearing the word rabbit may lead people to spell the word hair as hare is an example of a cognitive linguistic process. This process is known as semantic priming, where exposure to one stimulus influences a response to a subsequent stimulus, without conscious guidance or intention. In this case, hearing 'rabbit' activates associated words and their spellings, which can influence how someone spells a similar-sounding word, leading them to choose 'hare' instead of 'hair'. Semantic priming is part of our cognitive processes and how we interpret and produce language.

b. a nonpolar head and tail
c. a polar head and a nonpolar tail
d. a polar head and tail
Answers
Phospholipids contains a polarized head and a nonpolar tail due to their molecular makeup.
The head is hydrophilic and made up of a phosphate and glycerol unit while the tail is hydrophobic and made up of a saturated and unsaturated fatty acid in its structure
A phospholipid is composed of a polar head and a nonpolar tail. These components allow it to form a bilayer in cell membranes.
The correct option is c.
Explanation:A phospholipid is composed of a polar head and a nonpolar tail. The polar head is hydrophilic (water-loving), which means it is attracted to water.
The nonpolar tail, on the other hand, is hydrophobic (water-fearing), and not attracted to water.
This configuration makes phospholipids the perfect building block for cell membranes, and results in the formation of a phospholipid bilayer when in aqueous solutions, allowing them to separate the inside of a cell from its outside environment.

We live in the Cenozoic era, and scientists know more about this era and the epochs it's divided into than any other time period. Why is this?
Answers
Scientists have a better understanding of the Cenozoic Era, the era we live in, because it is the most recent and its geological record is well-preserved, containing clear evidence of past life forms, including mammals' rise to dominance after dinosaurs' extinction.
We live in the Phanerozoic eon, within the Cenozoic era, which is known as the Age of Mammals. This era is divided into different periods and epochs, including the Quarternary period and the Holocene epoch. The Cenozoic era began about 65 million years ago and continues to present day. It's characterized by the emergence and dominance of mammals, including human ancestors, after the extinction of dinosaurs.
Scientists know more about the Cenozoic era than any other time period because it is the most recent and therefore the best preserved in the geological record. During the Cenozoic, most of the organisms that we share Earth with evolved. Additionally, the closer proximity in time allows for better preservation and study of fossils, giving us clearer evidence of past life forms and environments.
Throughout the Cenozoic, Earth experienced significant climatic and geographical changes, such as the ice ages and tectonic shifts. These shifts contributed to the evolution and distribution of species. The ongoing nature of these changes, as well as human interest in understanding our own origins, drives the in-depth study of this era.
A large population of houseflies was sprayed with a newly developed, fast-acting insecticide. the appearance of some houseflies that are resistant to this insecticide supports the concept that
Answers
Final answer:
The presence of insecticide-resistant houseflies illustrates the concept of pesticide resistance and microevolution, where selective pressure from the use of pesticides leads to the survival and reproduction of resistant individuals, causing resistance to increase within the population over time.
Explanation:
The appearance of some houseflies that are resistant to a newly developed insecticide supports the concept of pesticide resistance and is an example of microevolution. This happens when a population of insects is subjected to a selective pressure, such as a chemical pesticide, and the few individuals that by chance carry genes that confer resistance to the insecticide are more likely to survive and reproduce.
Over time, these resistant genes are passed on to the offspring, and the resistance trait becomes more common in the population. Eventually, this could lead to the pesticide becoming ineffective, requiring higher doses or the development of a new pesticide. This cycle of development of insect resistance is a significant challenge in managing pest populations and has been observed since the usage of DDT in the 1940s.
