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.
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.

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
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.

Answer: In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.
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.
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.
Use the diagram below to answer the following questions for 1 point each:
1. Identify ONE similarity between mitosis and meiosis.
2. Identify ONE difference in the results of mitosis and meiosis.
3. Identify ONE difference in the processes of mitosis and meiosis.
1. They both involve duplication of a cell's DNA content.
2. Mitosis is for asexual reproduction and meiosis is for sexual reproduction.
3. Mitosis produces 2 cells and meiosis produces 4.
Meiosis and Mitosis both are the cell divisions which involve karyokinesis followed by cytokinesis. Meiosis is different from mitosis in the ploidy of the offspring produced. Meiosis involves 2 divisions whereas mitosis involves only one division. Four daughter cells are produced through meiosis whereas only two are formed from mitosis.
What is Mitosis and Meiosis?Cell division occurs in a cell through two processes which include Mitosis and Meiosis. Generally, all the cells undergo mitotic division whereas meiosis occur in the organisms which reproduce through sexual mode of reproduction.
Mitosis is the process through which a single parent cell divides to make two new daughter cells which contains equal amount of genetic material as that of their parents. Thus, called as equational division. Here, each of the daughter cell receives a complete set of chromosomes from the parent cell.
Meiosis is a special type of cell division also called as reductional division. This division occurs in the germ cells in the organisms which reproduce through sexual mode of reproduction for the production of gametes, such as sperm or egg cells. These gametes are haploid in nature as they receive only half of the set of chromosomes from the parent cell. Meiosis involves two rounds of divisions which ultimately result in the formation of four cells with only one copy of each chromosome.

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
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.
