Molecules that absorb light energy are called pigment.
What is pigment?A chemical that can be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants. any chemical that adds color.Chlorophylls are plant pigments that give plants their characteristic green hue. They are also the molecules in charge of the photosynthesis process, which converts light energy into chemical energy. Chlorophylls aid in blood oxygenation and thus aid in the body's detoxification.Chemical compounds known as pigments display visible light wavelengths, giving them their colorful appearance. A certain form of pigment is present in plants, flowers, algae, some photosynthetic bacteria, and even the skin of animals. This pigment provides color and has the capacity to absorb some wavelengths.

DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.
Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.
Explain why society has been developing different renewable resources in favor of
nonrenewable resources in the past few decades.
Answer: Society has been developing different renewable resources in favor of nonrenewable sources in the past decades because natural gas and oil has been used to much that we are running out of nonrenewable sources. So society has been trying to use solar panels, wind panels, and water.

Scientists determined that an unknown organisms was a eukaryote and not prokaryote. Which characteristic would have allowed them to make this determination?
Grupo de escolhas da pergunta
A) Nuclear envelope
B) Cell wall
C) DNA
D) Flagella
ASAP
Answer:
cell wall would have allowed them to make this determination
Scientists would have determined that an unknown organism was a eukaryote and not a prokaryote based on the presence of a nuclear envelope (Option A).
What is a nuclear envelope?The nuclear envelope is a double-membrane structure that surrounds the nucleus in eukaryotic cells and separates the genetic material (DNA) from the rest of the cytoplasm. Prokaryotes, on the other hand, do not have a distinct nucleus or a nuclear envelope. Instead, their genetic material is dispersed throughout the cytoplasm and is not separated from the rest of the cell
Options B, C, and D (cell wall, DNA, and flagella) could also be used to determine whether an organism is a prokaryote or eukaryote, but the presence of a nuclear envelope is a key characteristic that definitively separates the two types of organisms.

B. They monitor and react to changes in the body and its
environment
C. They release hormones that control the activities of cells and
organs
O D. They identify and destroy things that are foreign or harmful to the
body
Answer:
B
Explanation:
because the nerval system is for sending and capturing signals from the brain to monitor if you had a broken bone so your brain and nerves say you are feeling pain. on rare occasions the nerves will totally skip the pain part and send different information to your brain, like if you broke your finger, it would skip the pain and all you would see is a weird finger.
Describe how proteins form (polypeptide)
Answer: Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
Answer:
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Answer:
Syngamy: Syngamy refers to the fusion of gametes in fertilization.
Triple Fusion: Triple fusion refers to the fusion of a sperm cell with the two polar nuclei during the double fertilization in angiosperms.
Type of Fusion
Syngamy: In syngamy, a male gamete fuses with a female gamete.
Triple Fusion: In triple fusion, a male gamete fuses with the central cell.
Result
Syngamy: Syngamy produces the zygote that develops into the embryo.
Triple fusion: Triple fusion produces the endosperm cell that develops into the endosperm.
Ploidy
PloidySyngamy: The result of the syngamy is diploid.
Triple Fusion: The result of the triple fusion is triploid.
Type of Gametes
Type of GametesSyngamy: Both male and female gametes are involved in the syngamy.
Triple Fusion: Only male gametes are involved in the triple fusion.
Type of Fertilization
Syngamy: Syngamy is a generative fertilization.
Triple Fusion: Triple fusion is a vegetative fertilization.
Occurrence
OccurrenceSyngamy: Syngamy occurs in animals and plants.
Triple Fusion: Triple fusion occurs in angiosperms.
Conclusion
Syngamy and triple fusion are two types of events in the sexual reproduction of plants. Syngamy is the fusion of male and female gamete, producing the zygote. Triple fusion is the fusion of a male gamete with the central cell of the female gametophyte, producing the endosperm. The main difference between syngamy and triple fusion is the type of fusion of cells in each event.

1. What do DNA Replication and Cell Division have in common?
2. Define Cell Differentiation in your own words.
3. Why are stem cells consjdered unique?
Answer:
1: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. This process is called chromosome segregation.
2: Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
3: Stem cells have unique abilities to self-renew and to recreate functional tissues. Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times.

Explanation:
Magma come out of volcanoes that cools down and later on hardens up into rocks.
What is Magma?The existence of magma is essential to comprehending the geology and morphology of the mantle because the majority of the mantle and crust are solid.
Different types of magma form as a result of variations in the mantle's and crust's structural features, pressure, and temperature. Decompression Melting The mainly solid mantle of the Earth moves higher during decompression melting.
Convection causes this hot material to rise to a place with lower pressure.
Therefore, Magma come out of volcanoes that cools down and later on hardens up into rocks.
