Which of the following best describes the result of meiosis? Select 3 that apply.
WILL GIVE BRAINLIEST
The result of the process of meiosis is that it produces increased genetic diversity due to crossing over.
The correct option is C.
What is meiosis?Meiosis is a type of cell division that results in the production of gametes or sex cells. Hence. meiosis is a form of cell division that occurs only during sexual reproduction.
During meiosis, the cells of the parent organism which have a pair of chromosomes or diploid number or 2n of chromosomes divide to produce the gametes which have the haploid number or n number of chromosomes.
Hence, the sex cells or gametes produced can fuse to form a zygote that has a pair of chromosomes or diploid number or 2n of chromosomes.
The process of meiosis results in genetic variation as it allows for the crossing over of genes, such that the genes of the offspring show a variation to that of the parents as well as among the offspring.

Which of these shows an example of an insertion mutation?
The figure 3 shows an example of an insertion mutation.
What do you mean by insertion mutation?
An insertion is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping.
Moreover, an insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly.
An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated.

Remote sensing data helps scientists improve their understanding and predictions about climate change.
a. True
b. False
Remote sensing data helps scientists improve their understanding and predictions about climate change. This is a true statement.
It allows for the monitoring of Earth's surface, oceans, and atmosphere at various spatiotemporal scales, enabling the study of processes or long- and short-term events related to the climate.
Remotele sensing photos, which are captured with specialised cameras, are used by scientists to "feel" the Earth. Examples include: We can see considerably more from the air and space than we can from the ground because of the cameras on satellites and aircraft that snap photographs of large swaths of the Earth's surface.
For example, isotope ratios, elemental analysis, biomarkers, and biogenic silica are examples of chemical proxy records. When combined, these proxies allow us to recreate the climate from hundreds of millions of years ago.

The sympathetic branch of the autonomic nervous system raises heart rate, blood pressure, and breathing to get the body ready for exercise. The sympathetic division also encourages the liver to release glucose for use as fuel.
To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The primary function of the parasympathetic nervous system is to calm down or lessen your body's activity. The rhyming expressions "rest and digest" or "feed and breed" are good methods to remember what your parasympathetic nervous system performs because of the messages they carry. When a person is confronted with a dangerous or terrifying scenario, one component of the autonomic nervous system, known as the sympathetic nervous system, reacts.

Hydrogen bonding is a type of force that occurs inside of molecules.
A. False
B. True
Answer:
[tex]\Huge \boxed{\textbf{B. True}}}[/tex]
Explanation:
Hydrogen bonding plays an important role inside many molecules. It occurs due to an electrostatic attraction between a hydrogen atom bonded to an electronegative element like oxygen or nitrogen, and another nearby electronegative atom that possesses a lone pair of electrons. This second atom acts as an acceptor for the hydrogen.
The hydrogen is pulled slightly toward the acceptor due to their opposing charges. These hydrogen bonds can form both between different molecules as well as within different parts of the same molecule.
They are stronger than the normal attractions between permanently polarised molecules or non-polar atoms. However, hydrogen bonds are not as intensely strong as true covalent bonds, which involve sharing electrons, or ionic bonds that transfer electrons.

The process of how the teepee landform started and how it changed and became what it looks like now is given below.
How were the teepee rocks formed?Teepee (sometimes written tepee or tipi) structures are sedimentary structures considered to suggest formation in peritidal environments. Teepees are mostly the consequence of water evaporation and subsequent mineral precipitation from sediment, which causes expansion and buckling to form a shape like a teepee.
Native Americans of the Plains were nomadic hunters, thus they needed to be able to shift their sites fast and have a portable, strong, water-resistant shelter. The Tipi was often made of tanned buffalo skin and was simple to take apart and erect.
Therefore, tipi, also known as a teepee, is a sort of cone-shaped shelter that was historically constructed using wooden poles and bison hides for the roof and walls. Though it has undergone some modification in terms of beautification, it is still in use up till today.

1. which carbon source will lead to greater atp production via cellular respiration: a 6-carbon saturated fatty acid vs. a 6-carbon carbohydrate? why?
A 6-carbon saturated fatty acid produces more ATP than a 6-carbon carbohydrate.
Due to the greater number of electrons that a 6-carbon fatty acid can access, it will produce more ATP.
Because the carbons in a fatty acid's backbone are more reduced (contain more electrons) than those in a 6 carbon carbohydrate, the fatty acid is 6 carbon saturated. More NADH/FADH2 produces more ATP during cellular respiration, which is a result of more electrons.
This higher production of ATP results from the higher yield of acetyl-CoA molecules created from fatty acids (3 acetyl-CoA molecules per 6 carbon atoms) as compared to glucose, rather than ATP produced as a result of the -oxidative process (2 acetyl-CoA molecules per 6 carbon atoms).

The cochlea sends information about sound stimuli to the cochlear nucleus of the brainstem via auditory nerve fibres.
Depending on whether receptor cell population in the cochlea is contacted, the neurons that give rise to these fibres can be split into two categories.
Basically, vibrations (sound signals) are transmitted to the brain via the auditory nerve. Remember that hearing sounds is made possible by several different parts of the ear, not just the auditory nerve. A number of additional ear components are also involved.
Some sensory systems that provide information that is relevant to motor functions are distinguished by a "spatial code" in addition to a "temporal code" because they display characteristics that are tailored to specific spatial directions.
