How might retaining too much heat be a disadvantage to an organism?
Answers
Answer:
Too much heat can disrupt subcellular structures such as membrane proteins, and enzymes while damaging the integrity of the plasma membrane.
Explanation:
Proteins are macromolecules made up of amino acids. These fold and bond to form several biologically important molecules. For instance, enzymes, a special type of protein functions by providing alternative reaction pathways. They work best at a specific pH and optimal temperature range, beyond which they become non-functional or denatured entirely.
The denaturing of proteins occur at high temperatures, and alter protein folding, bonding and other types of behavior. Furthermore, membrane proteins are important for regulating cell function. If these are disrupted, the system cannot maintain homeostasis i.e a constant internal environment.

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
Answers
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

explain how the repiratory and the circulatory system work together. To make gas exchange possible.
Answers
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.

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.

How does DNA polymerase move along each strand of DNA?

C. One moves towards from the replication fork and the other moves away from it
D. There is only one DNA polymerase on the DNA at a time
Answers
Answer:
c i think
Explanation:
Answer:
B
Explanation:
This sort of replication, since it involves one nucleotide being placed right after another in a series, is called continuous. Whereas the DNA polymerase on the leading strand can simply follow the replication fork, because DNA polymerase must move in the 5' to 3' direction, on the lagging strand the enzyme must move away from the fork.
Would you expect the entire crop grown from your preferred stalk to show the characteristics of the parent crop? Explain your answer.
Answers
Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.

which is the smallest unit of measurement? (out of these) centimetre micrometre millimetre nanometre
Answers
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.

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
Answers
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).
