Answer:
B is correct
Explanation:
A is incorrect because the type of carbon that comes from food is not carbon dioxide.
C is incorrect because the carbon dioxide that comes from factories is part of that cycle, which mean there is no extra carbon, it's just an extra carbon molecule.
D is incorrect because as everyone knows, factories are not living things.

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells.
Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication
Answers
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand? Explain your reasoning for your response using an example DNA sequence. and this is for biomedical science.
Answers
Answer:
Yes
Explanation:
DNA, which is the genetic material, is a double-stranded molecule i.e. possess two strands. Each strand is made up of a sequence of nucleotide base, which are complementary to one another. The complementary base pairing rule as proposed by Chargaff states that Adenine (A) base will always hydrogen pair with Thymine (T) base while Guanine base (G) will always pair with Cytosine (C) i.e. A-T, G-C.
For example, If the sequence of nucleotides of one strand was CTAGCGGATC, the sequence of nucleotide of the other strand will be GATCGCCTAG. Hence, based on this question, the information of the sequence of base on one strand can be used to determine the sequence of the second strand.

help asap!! "Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates
A) relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation
B) innate variability because plants have evolved molecular differences to an environmental stimuli
C) unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light
D) inclusive fitness because differences in chlorophyll pigments increase the proliferation of beneficial traits in the population
Answers
Answer:
A
Explanation:
This molecular variation in plants illustrates relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation. The correct option is A.
What is relative fitness?Absolute fitness is normalized relative fitness. It is a biological fitness measure that compares the reproductive rate of a genotype or phenotype to the maximum reproductive rate of other genotypes or phenotypes in a given population.
The contribution of an individual to the next generation's gene pool in comparison to the contributions of other individuals.
It is important to remember that natural selection acts both directly on the phenotype and indirectly on the genotype that controls that phenotype.
Because the molecular adaptations in chlorophyll pigments have been passed down to the next generation, this molecular variation in plants demonstrates relative fitness.
Thus, the correct option is A.

The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.
What is brain?
The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath. This arrangement is reversed in the spinal cord, where the gray matter is located within and the white matter is on the outside.
Therefore, The correct option is D. The brain, part of the nervous system, sends a message to the eyes to detect the ball and then the nerves swing the bat.

What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answers
Answer:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
Unlike food chains, food webs show more detailed information about the different animals in an ecosystem and show multiple energy transfers to different animals from the same sources.
By looking at these examples, you will notice a dramatic difference in detail:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
What is food chain?Food chain shows the relationship between organisms by the food they eat.
What is food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Difference between food chain and food webFood webs show interconnection of food chains about the different animals in an ecosystem and different energy transfer processes.
Thus, food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

10. Solve What is the chemical formula of this
organic compound?
Answers
Answer:
Explanation:
The structure represented in the picture attached to the question is a benzoic acid (which is an organic compound).
8. The type of bond present between the carbon-carbon, carbon-hydrogen and carbon-oxygen atoms in the compound (same as other organic compounds) is a covalent bond. This is because oxygen and hydrogen share there valence electrons with carbon; oxygen has two valence electrons and thus it is surrounded with two bonds and hydrogen has one valence electron and thus surrounded with one bond.
9. The elements present in this compound, as can be seen in the picture, are carbon, hydrogen and oxygen which is the reason it is referred to as an organic compound.
10. The chemical formula of this organic compound is C₆H₅COOH. The "cyclic" structure (aromatic structure) there shows that it is a derivative of benzene (because of the presence of the alternating double bonds) while the carboxylic group there has to be written separately in the formula.
