It is believed mitochondria evolved from
,
while chloroplasts evolved from
Answers
Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

In a diploid plant species, the proportion of progeny expected to be tall and produce round fruit is 32%.
In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. The expected percentages of progeny phenotypes are tall oval = 41%, short round = 41%, tall round = 9%, and short oval = 9%.To determine the proportion of progeny expected to be tall and produce round fruit, we need to consider the alleles for each trait. Allele D produces tall plants (dominant) and allele d produces short plants (recessive). Allele R produces round fruit (dominant) and allele r produces oval fruit (recessive).From the given percentages, we can deduce that tall ovals and short ovals combined make up 9%. Since tall oval is 41% and short oval is 9%, the proportion of progeny expected to be tall and produce round fruit is 41% - 9% = 32%.Therefore, the proportion of progeny expected to be tall and produce round fruit is 32%.For more questions on diploid plant

What is the flexibility of spider silk determined by the structure of its molecules
Answers
The flexibility of spider silk determined by the structure of its molecules is quite strong.
The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.
The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.

state and explain five uses of insects
Answers
Answer:
They help our eco system
Explanation:
PROVIDERS
Insects are in nearly every food chain. Many larger animals—birds, bats, amphibians, and fish—eat insects before they in turn are eaten by predators. The dearth of insects is suspected to be a leading cause of recent declines in bird populations.
DECOMPOSERS
Waste-eating insects unlock nutrients for use by the ecosystem that would otherwise stagnate in dung, dead plants, and carrion. Dung beetles process parasite- breeding and grass-killing cattle dung in 23 months versus the 28 it would otherwise take.
PEST CONTROLLERS
By feeding on crop-threatening pests, predatory insects perform the role of pesticides without chemicals. This cuts pest-control costs and increases yields, saving agricultural industries billions of dollars every year—while reducing toxic pesticide residue on crops.
POLLINATORS
Nearly 90 percent of flowering plant species and 75 percent of crop plant species depend on pollination by animals—mostly insects. Overall, one out of every three bites of food humans eat relies on animal pollination in the production process.
SOIL ENGINEERS
Termites (and ants) can trans- form soil in hot, dry climates. Their tunneling aerates hard ground, helping it retain water and adding nutrients. In some regions, the introduction of termites has turned infertile land into cropland within a year.
Answer:
Pollination, Food, Silk, Dyes, Dermestids for cleaning skeletons.
Explanation:
Pollination. Honeybees are among the most important of pollinators, and their efforts result in about 80% of all pollination in the United States.
Food. Honey is made by insects and can be consumed by humans.
Silk. Most silk is produced from the cocoons of the Silkworm.
Dyes. Many insects provide dyes that are used in cosmetics and for coloring cakes, medicines and beverages.
Dermestids for cleaning skeletons. Carpet beetles feed on almost anything organic and have been used in museums by technicians to clean the skeletons of mammals.

The DUMP molecule acts as a direct precursor for the production of dttp.
Deoxyuridine monophosphate (dUMP), a type of uridine monophosphate (UMP) that has undergone oxygenation, is a precursor to deoxythymidine monophosphate (dTMP), a substance needed for the production of DNA nucleotides. By substituting a hydrogen atom for the hydroxyl group at the 2' carbon of ribose, UMP is deoxygenated to form dUMP.
In its conjugate acid and conjugate base forms, deoxyuridine monophosphate (dUMP), a deoxynucleotide, is also known as deoxyuridylic acid or deoxyuridylate. It belongs to the group of chemical substances known as pyrimidine 2'-deoxyribonucleoside monophosphates.
In the multienzyme complex responsible for deoxynucleotide production, thymidylate synthase interacts with dCMP deaminase to convert dUMP to dTMP. Hexameric human dCMP deaminase has 178 amino acids, a zinc-binding domain, and.

What is the difference between blue green and fungi?
Answers
Blue-green algae are photosynthetic prokaryotes, while fungi are eukaryotes that obtain nutrition through absorption.
Blue-green algae and fungi are both organisms, but they belong to different domains and have distinct characteristics. Blue-green algae, also known as cyanobacteria, are classified under the domain Bacteria, while fungi belong to the domain Eukarya.
Blue-green algae are prokaryotic organisms, lacking a true nucleus and membrane-bound organelles. They obtain energy through photosynthesis and are capable of converting sunlight into chemical energy. They typically inhabit aquatic environments, such as lakes, ponds, and oceans, and some species can fix atmospheric nitrogen.
On the other hand, fungi are eukaryotic organisms with a distinct nucleus and membrane-bound organelles. They obtain nutrition by absorbing organic matter from their surroundings. Fungi play crucial roles in decomposition and nutrient cycling in ecosystems. They can be found in various habitats, including soil, plants, and even as symbiotic partners with other organisms, such as in mycorrhizal associations.
In summary, the primary differences between blue-green algae and fungi lie in their cellular structure, mode of nutrition, and classification. While blue-green algae are photosynthetic prokaryotes, fungi are eukaryotes that obtain nutrition through absorption. Understanding these distinctions helps in appreciating the diversity and ecological significance of these two groups of organisms.
