Answer:

CF is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, ΔF508, is a deletion (Δ signifying deletion) of three nucleotides that results in a loss of the amino acid phenylalanine (F) at the 508th position on the protein.

Answer: The skeletal system is used to support structure for your body. It's able to give your body shape and also movement to help walk around, and run. It also makes blood cells in your body and form a protection for your organs, storing minerals as well. These are the main functions.

Hope this helps!

Option C: Natural selection favored alleles for light skin in Europe.

The theory of Natural Selection was firstly expounded by Charles Darwin. It is a key mechanism of evaluation, the change in the heritable traits, and characteristic of a population over a generation.

Natural selection favored alleles for light color skin in Europe because of the well-known correlation between skin pigmentation and distance from the equator. Relethford strongly suggests that natural selection in response to environmental factors plays an important role in the geospatial patterning of human skin pigmentation variation. The lighter level of UVR required to synthesize vitamin D, which is higher in individuals with dark color skin means the region near the equator. The European region does not receive much UVR that's why in Europe alleles of light skin are favored.

The temporal lobe neurons show Plasticity.

According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.

Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

Production of recombinant gametes is a likely result of crossing over during meiosis I.

What is recombination ?

Recombination can be defined as the process where DNA fragments are under go breakage and recombined to generate new allele combinations.

This mechanism will generate genetic diversity at the gene level in which variations in the DNA sequences of various organisms will be reflected.

In the field of heredity, recombination is the process which produce gametes with new allele combinations that were absent in the gametes of previous generations.

one of the type of recombination called Intrachromosomal recombination takes place between independently assorted alleles with loci on distinct chromosomes.

Crossover occur among loci within identical chromosomes in case of intrachromosomal recombination which is essential to keep in mind that recombination takes place during meiosis in both of these situations.

Answer:

1.94 g/mL

Explanation:

Following Archimedes' principle, the displaced volume of an object (meaning the volume of water it displaces if completely submerged in it) is equal to the object's volume.

Thus the volume of this Halite sample is 17 mL.

The density of an object is equal to the mass divided by the volume:

Copy number changes is considered as genetic changes which does not lead to the formation of oncogenes.

Copy number change- The cytogenetic level of resolution, known as copy number variation (CNV), involves both duplications and deletions of sequences that generally have lengths between 1,000 base pairs and 5 megabases.

Genetic Change- Genetic mutations, which occur as our cells divide and generate duplicates of themselves, are modifications to your DNA sequence.

Base Pairs- The DNA molecule is made up of two bases (or nucleotides) that contain nitrogen. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T). These bases come in certain pairings (A with T, and G with C).

Answer:

One of the 10 human body systems that each organ is a part of. These bodily systems are linked and rely on each other in order to work. The brain and neurological system must interact with the heart in order for it to beat.  Furthermore,the nutrients that our digestive system provides to our skeletal system help it create strong and healthy bones. The body's cells receive water, oxygen, salt, plus nutrients from the circulatory system. The epidermis, respiratory, and excretory systems all function to remove wastes from the cells. With the help of sweat glands, the skin functions as just another excretory organ to remove waste from the body. Through sweat, it removes water, salts, plus urea out from body.
