What usually happens to an ecosystem after a sudden catastrophic change?
Please answer quickly
Answer:
Explanation:
What occurs is ecological succession. When an entire ecosystem is suddenly changed due to a catastrophic scenario it gets replaced by another. Other plants or animals replace the ones that got wiped out in an event such as a big forest fire or flood. Only if the place of the catastrophe somehow becomes uninhabitable another ecosystem won't come out of the old one.

1. Name the 4 biomolecules that are found in different foods:
Answer:
Carbohydrates, proteins, lipids and nucleic acids.
Explanation:
Biomolecules are organic and are carbon containing and are of four types which are carbohydrates, proteins, lipids and nucleic acids.
Carbohydrates are part of our major diets and are found in grains, fruits and vegetables and so on.
Carbohydrates are energy producing food through glucose.
Lipids contain both fat and oil and they are hydrocarbon and non polar molecules that don't dissolve in water. They provide energy, insulation in the environment and are major constituent of plasma.
Proteins are organic molecules found in meat, milk, beans, cheese e.t.c.
They are body building food or serve as building blocks.
They are enzymes and hormones which are involved in body mechanisms.
Nucleic acids are composed of deoxyribonucleic acid(DNA) and ribonucleic acids. They are the genetic constituent of living organisms and they carry the genetic information.

Where do chromosomal mutations begin?
Why do chromosomal mutations occur?
Answer:
A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).
Explanation:
Brainliest please?
Answer:
1) Different types of chromosome mutations can originate in the germinal cells.
2) Chromosome mutations are alterations occurring in chromosomes that typically result from errors during nuclear division or from mutagens. ... Abnormal chromosome numbers result from nondisjunction, or the failure of chromosomes to separate correctly during cell division.

if random chromosome alignment already shuffles chromosomes around so the eggs and sperm get a good mix of some “mom” alleles and some “dad” alleles, why do we even need to do crossing over
Answer:
The correct answer is - to produce recombinant that leads to genetic variation.
Explanation:
Random shuffling or random alignment of the chromosome during gamete formation allows the formation of new allele combinations. In the crossing over the parts of the homologous chromosomes are switched between homologous and recombinants are formed that shows are genetic variation.
So, now they have different allele combinations and chromosome combinations as well. Random shuffling does not provide genetic variations as crossing over

Noah is a 3-year-old boy recently diagnosed with epilepsy. He presented to his pediatric advanced practice registered nurse (APRN) in a primary care clinic with 2 weeks of increased seizure activity after a medication change. Symptoms also included a sudden increase in lethargy, ataxia, and drowsiness. Test results showed elevated ammonia, liver function, and an abnormal electroencephalogram reading. Which cell organelle is not working properly?
Answer:
Mitochondria
Explanation:
Mitochondrial diseases are a group of diseases caused by dysfunctional mitochondria, organelles that generate energy for the cell. Mitochondrial diseases are often caused by mutations, acquired, or inherited in the mitochondrial DNA or nuclear genes that code for respiratory chain complexes in the mitochondrion. Mitochondrial diseases involve multiple organs and show heterogeneous and unpredictable progression. The most common clinical presentation of mitochondrial diseases is encephalomyopathy, and epileptic seizures can frequently occur as a presenting sign of mitochondrial encephalopathy.

Question #4
Bacteria called thermophiles have been discovered that can live in natural hot springs unlike most
bacteria that cannot survive extreme heat. Using genetic engineering techniques, the heat resistant gene
in these thermophiles has been isolated and then inserted into wheat and corn cells in an attempt to
develop crops that can withstand global warming.
Which statement suggests a possible reason for inserting the thermophilic gene into the crops?
A
The wheat and corn now have increased tolerance to increased salinity levels, so the enzymes
inside their cells will not be denatured by salt allowing them to survive as the sea level rises.
B
The wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not
be denatured by extreme heat, allowing them to survive the increase in global temperatures.
С
The wheat and corn now have increased tolerance to cold, so the enzymes inside their cells will not
be denatured by extreme cold allowing them to grow in the Antarctic and Arctic regions.
D
The wheat and corn now have increased tolerance to a lower pH, so the enzymes inside their cells
will not be denatured by changing pH due to increased global temperatures allowing them to
survive
Nuaction #5
Answer:
D
Explanation:
A genetically modified organism (GMO) is any organism whose genetic material (DNA) has been modified by genetic engineering. In agriculture, GMO plants with resistance to abiotic and biotic factors have been developed.
The statement "the wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not be denatured by extreme heat, allowing them to survive the increase in global temperatures" suggests a possible reason for inserting the thermophilic gene into the crops (Option B).For example, Bt crops are GMOs capable of synthesizing proteins that are selectively toxic to insect pests but are innocuous to humans and animals. These GMO crops (Bt crops) were developed by inserting certain genes from Bacillus thuringiensis (Bt) bacteria into corn and cotton.Some genetic engineering techniques used for inserting genes and thus develop GMOs include the use of viral vectors, microprojectile bombardment, electroporation. microinjection, etc.In conclusion, the statement "the wheat and corn now have increased tolerance to heat, so the enzymes inside their cells will not be denatured by extreme heat, allowing them to survive the increase in global temperatures" suggests a possible reason for inserting the thermophilic gene into the crops (Option B).

explain how the repiratory and the circulatory system work together. To make gas exchange possible.
Answer:
here's the more, get to the point answer: so the circulatory system is responsible for gas exchange between tissues and blood that we need. All living creatures (including us) have blood and that blood absorbs oxygen and releases carbon dioxide to/in the lungs (respiratory system). Thus the circulatory and respiratory system helps us to obtain oxygen and discharge carbon dioxide
Explanation:
hope this helps
Answer:
The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

which is the smallest unit of measurement? (out of these) centimetre micrometre millimetre nanometre
Answer:
Nanometer
Explanation:
A Nanometer is 1000 time smaller than a Micrometer and a micrometer is 1000 time smaller than a millimetter and so on.
The smallest unit of measurement among the options given is the nanometre (nm).
What is the unit of measurement?A unit of measurement is a defined quantity used to express a physical quantity such as length, mass, time, volume, or temperature. Units of measurement provide a standard reference for comparing and measuring physical quantities.
There are several systems of units used around the world, including the International System of Units (SI), the British Imperial System, and the United States Customary System. The SI system is the most widely used system of measurement, and it is based on the metric system.
SI units are defined using a set of base units, such as the meter for length, the kilogram for mass, and the second for time. Other units, such as the Newton for force or the Watt for power, are derived from these base units.
In addition to the SI units, there are also non-SI units that are widely used in various fields, such as the Angstrom for measuring atomic distances in chemistry and the knot for measuring speed in marine and aviation industries.
