Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
Explanation:
what are the consequences of overdrawal of water?
Answer:
As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).

1. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on light-colored substrates.
2. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates.
3.Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the light, rocky, granite substrate.
4. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the dark, rocky lava substrate.
5. Which fur color seems to have the greatest overall selective advantage?
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13frequencies of dark-colored mice ≅ 0.873)
q² = 0.74p² = 0.02 2pq = 0.244)
q² = 0.13p² = 0.42pq = 0.465)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

refers to the Linnaeus' method of naming species
using a unique two-word name made up of the genus and species name.
O cell organelle
O level of cladistics
O binomial nomenclature
O method of taxonomy
Answer:
binomial nomenclature
Explanation:
Binomial nomenclature as the name implies (binomial = two, nomenclature = naming) is a system of naming organisms that comprises of two unique Latin word names. The binomial nomenclature is a system of naming that was proposed by the man referred to as the FATHER OF TAXONOMY, CAROLUS LINNAEUS.
According to this system of naming organisms, the two names are the generic and specific epithet of the organism respectively. For example, in dog, which is Canis familiaris, Canis is the generic name while familiaris is the specific name.

Question 4 of 10 What is the difference between science and pseudoscience? O A. Science is done only in a laboratory, while pseudoscience is done in the real world." B. Pseudoscience is based on empirical evidence, while science is based on observation and experimentation. C. Scientific claims are biased, while pseudoscientific claims are unbiased. O D. Scientific claims can be verified through observation and experimentation, while pseudoscientific claims cannot SUBMIT
Explanation:
The difference between science and pseudoscience is that science relies on experimentation and data gathered.
Pseudoscience is based solely on one's opinion rather than fact. in the early 1800's, scientists used to speculate what type of a person you are or intelligence by the shape of your head.
how is the law of mendelian inheritance violated in down's syndrome
Answer:
According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.
In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

Explanation:
Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.
Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.
Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.

1. Tell what type of interaction is being performed by the following pairs of
organisms. (Commensalism, Mutualism, Competition, Parasitism and
Predation)
6. aphid and rose plant
9. butterflies and flowers
10. birds and worms
7. lion and buffalo
8. coral reefs and fishes
Answer:
6. Parasitism
9. mutualism
10. predation
7. predation
8. mutualism
Explanation:
Living organisms, in their natural habitat, forms certain relationships with one another. These relationships are as follows:
- Mutualism is the association of two organisms in which both organisms benefits from one another in the relationship. Example is butterfly and flower in this question, where the butterfly helps pollinate the flower while the plants provide food source for the butterfly. Another example is coral reefs and fishes where the fishes and coral depend on one another.
- Predation is the kind of relationship in which one living organism called PREDATOR kills and feeds on another called PREY. Examples are the relationship between birds and worms, lion and buffalo where the bird and lion are predators while worm and buffalo are preys.
- Parasitism is the relationship between two organisms in which one organism called PARASITE lives on and derive nourishments from another organism called HOST. In the example of aphid and rose plant where the aphid is the parasite and rose plant is the host.
The type of interaction that is being performed by the following pairs of
organisms include the following:
Aphid and rose plant - ParasitismButterflies and flowers - MutualismBirds and worms- PredationLion and buffalo - PredationCoral reefs and fishes - MutualismAphid and rose plant have a parasitic relationship due to the aphids taking
up vital nutrients from the rose plant thereby resulting in distorted growth.
Butterflies and flowers have a mutualistic relationship as the butterfly aids
pollination of the flowers and also derives food and juice in return.
Birds and worms have a predatory relationship as the birds eat worms for
food and survival.
Lion and buffalo have a predatory relationship as the Lions eat buffalos for
food and survival.
Coral reefs and fishes have a mutualistic relationship as the fishes aids
reproductive ability of the coral reefs while the fishes benefit food and habitat in return.

A scientist uses radioactive nitrogen to label the nitrogenous bases of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive DNA? Explain.
I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.
Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.
Sorry if im wrong
Answer:
I would say one..
