What happens during radioactive decay?
answer: Parent isotopes turn into daughter isotopes
Answers
Answer: I hope this helps. Let know if this right or wrong. Have a good day
Explanation:
When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion.During radioactive decay, an unstable nucleus emits subatomic particles to attain stability. It may undergo transmutation to change to some other nucleus or may achieve a stable state by giving off energy in the form of photons. Radioactive decaya radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.

Plants in grasslands would not benefit from adaptations that protect against grazing. please select the best answer from the choices provided t f
Answers
Generally speaking, grasslands are lands where the predominant plant cover is grasses. In general, savannas are grasslands with sporadic trees. Grasslands and savannas make up around 5% of the surface of the Earth.
Adaptations that defend against grazing would not be advantageous for plants in grasslands. FALSE.
Which of the following traits would a savanna plant have?Vegetable Adaptations
Most savanna tree adaptations are to dryness, including long tap roots to reach deep water tables, strong bark to resist annual fires (thus the prevalence of palms in many locations), deciduousness to prevent moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).
But there are also naturally occurring trees in non-forested places like grasslands and savannas. The trees can be found in dense lots or in random places. This implies that many of these places will have more than 10% tree cover and seem to be degraded forests when seen from above.
In grasslands, the predominant plant species are grasses; however, sedge and rush families can also be present, along with varying amounts of various herbs and legumes like clover. Except for Antarctica, all continents have natural grasslands. The majority of Earth's ecoregions contain grasslands.
The grassland ecology benefits from the natural occurrence of fire since it keeps it strong and healthy. It increases the soil's temperature and lessens the annual buildup of leaf litter, allowing sunshine to enter.

tumor suppressor genes make up another group of genes that regulate cell division. genes from this group produce proteins that signal cells when they are getting too crowded, proteins whose function is to repair dna, and still other proteins that regulate apoptosis (pre-programmed cell death). a tumor suppressor gene called p53 causes apoptosis when the cell is worn out or when defects are detected. where in the cell cycle would a tumor suppressor gene repair dna?
Answers
In the cell cycle, tumor suppressor gene will repair DNA in G2 phase.
G2 (Gap 1 phase) is the transition phase between S phase and M phase, in G2 phase cell prepare itself from mitosis.
When DNA is damaged, signaling pathways are initiated that causes cell cycle arrest in G2 phase.
p53, which is frequently disabled in a wide range of human cancers, including brain tumors, leukemias, lymphomas, sarcomas, and carcinomas of numerous tissues, including the breast, colon, and lung. The most common target of genetic alterations in human malignancies is p53, which may be involved in up to 50% of all cancers. It is also intriguing that a rare hereditary cancer syndrome, in which affected individuals develop any one of a number of different kinds of cancer, is transmitted genetically through p53 mutations. Similar to Rb, the oncogene proteins of SV40, adenoviruses, and human papillomaviruses also target the p53 protein.
the product of the p53 gene controls both apoptosis and the progression of the cell cycle. DNA damage prompts the rapid induction of p53, which triggers transcription of the Cdk inhibitor p21.As a general inhibitor of Cdk/cyclin complexes and by binding to PCNA (proliferating cell nuclear antigen), the inhibitor p21 prevents the progression of the cell cycle. The cell cycle is likely stopped as a result, giving damaged DNA time to be fixed before it reproduces. This damage-induced cell cycle arrest is prevented by the loss of p53, which results in an increase in the frequency of mutations and general genome instability. Oncogenes and tumor suppressor genes may also be altered as a result of this genetic instability, which is a characteristic of cancer cells.

All living organisms, including plants, animals, and microorganisms, carry out some form of cellular respiration in order to release energy to perform their daily activities. In which of the following Earth cycles do the products of cellular respiration play a major role?
Answers
Answer:
Carbon Cycle
Explanation:
Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it.
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere.

Forms when ice crystals reach the earth’s surface without passing through a liquid phase
Answers
Snow. Snow forms when ice crystals reach the earth’s surface without passing through a liquid phase.
Snow is a type of precipitation that occurs when water vapor in the atmosphere freezes into ice crystals. The shape and size of the snowflakes depend on the temperature and humidity of the air.
Snow can fall as light flakes, heavy flakes, or pellets. Snow can accumulate on the ground and form snowpacks, drifts, or avalanches. Snow can also melt and refreeze into ice or slush.
Some examples of snow-related topics are:
Snowflakes: the individual ice crystals that form snow. Snowflakes have a hexagonal symmetry and a variety of patterns. No two snowflakes are exactly alike.
Snowstorms: weather events that produce a large amount of snow in a short period of time. Snowstorms can cause low visibility, strong winds, and cold temperatures. Snowstorms can also create hazards such as power outages, traffic accidents, and frostbite. Some types of snowstorms are blizzards, nor'easters, and lake-effect snow.

The purpose of transcription is to create an RNA copy of the DNA sequence.
The act of copying information from a strand of DNA into a fresh messenger RNA molecule is called transcription (mRNA). DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei. The same information as DNA is carried by mRNA, which can readily leave the nucleus and is not employed for long-term storage, making it similar to a copy from a reference book. Because its sequence is complementary to the DNA template, the mRNA is not an exact replica of the DNA segment even though it includes the same information.

Where are phospholipids found in food?
The plasma membrane, the top layer of animal cells, is largely made up of phospholipids.They are made up of fatty acid chains joined to a glycerol backbone, just like fats.Phospholipids have two fatty acids that contribute to the formation of a diacylglycerol, as opposed to triglycerides, which have three fatty acidsPhospholipids are amphiphilic lipids consisting of a glycerol backbone or an amino-alcohol sphingosine backbone, which is esterified to one or two fatty acids, a phosphate group and a hydrophilic residue.Good sources of phospholipids include eggs, organ meats, lean meats, fish, shellfish, cereal grains, and oilseeds, particularly the choline phosphatides phosphatidylcholine, sphingomyelin, and lysophosphatidylcholine. Glycerophospholipids and sphingolipids are two kinds of lipids that make up the significant class of membrane lipids known as phospholipids. The cell membrane is composed of phospholipids, which are created when glycerol interacts with two fatty acids and a phosphate group.One phosphorus atom and four oxygen atoms combine to generate the complex ions known as phosphotes.Another form of lipid that does not contain glycerol is steroids. A phospholipid is a molecule made composed of a glycerol backbone, two fatty acids, and a modified phosphate group.The phosphate can change by having polar or charged chemical groups added to it. These hydrophilic and hydrophobic characteristics of phospholipids lead them to group into two layers when cellular membranes are formed.Because they are hydrophobic, the phosphate tails in between the layers of heads avoid contact with the water while the heads in each layer face the aqueous or watery environment on either side.
