what is the effect of telomere caps on cancer cells?
The telomere caps help to maintain genome integrity. In consequence, these repetitive sequences are fundamental to avoid the generation of cancer cells.
Cancer cells are a type of cells that proliferates in an uncontrolled manner, which is generally associated with mutations in the genome capable of altering normal gene expression patterns.
Telomere caps are repeated nucleotide sequences found at the end of chromosomes, which help to maintain genome integrity.
The elimination of these repetitive sequences (telomere caps) due to successive cell divisions triggers chromosomal (genome) instability and thus contributes to the emergence of genomic rearrangements that may lead to carcinogenesis.

c. kyphosis
d. xrostomia
The term that describes the muscle wasting Brenna's mother is experiencing is sarcopenia. That is option A.
An overweight individual is an individual whose body mass index is between 25 to less than 30.
Body mass index is calculated based on the weight and height of an individual.
An Brenna's mother advances in age, she begins to experience lost of muscle mass.
This is because of the following:
decline in hormones and numbers of neuromuscular junctions, increased inflammation, declines in activity, and inadequate nutrition.This will in turn lead to difficulty with walking and climbing stairs.

in gel electrophoresis, a loading dye is usually added to the sample of dna to be loaded in the wells of the gel. why would this be important?
Answer:
Gel loading dye is typically made at 6X concentration (0.25% bromphenol blue, 0.25% xylene cyanol, 30% glycerol). Loading dye helps to track how far your DNA sample has traveled, and also allows the sample to sink into the gel. ... It is important to use the same running buffer as the one used to prepare the gel.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?
Answer:
Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins

Answer:
A.) Low-pressure systems are usually associated with clouds and precipitation that minimize temperature changes throughout the day
B.) The slightly inward moving air in low pressure causes air to converge and since it can’t move downward because of the surface, the air is forced upward, leading to condensation and precipitation

What differences are there in the growth of the human population compared to the animal/plant population?
Answer:
Explanation:
In both plants and animals, there are parts of the body designed to carry the nutrients needed for growth. In a animal it is blood and in a plant, it is the Xylem and Phloem Tissue Humans are born with a set number of limbs and if one get's cut off it cannot regenerate. Because of this, we are increasingly cutting into resources that other species must use in order to survive. We have hindered, or even ended the lives, of numerous species. Today, 99% of the species still remaining on this planet are at risk because of human activity alone.The similarities in the population growth of humans with respect to plants and animals is that, in the three cases, the growth occurs exponentially with respect to the initial number of specimens

16. Which organelle may have allowed early eukaryotes to make food and produce oxygen? (a) the Golgi apparatus (b) the central vacuole (c) the plastids
Answer:
the plastids
Explanation:
Answer:
The plastids are the organelles that compose the cells of plants and algae. These contain chloroplasts, which allow them to capture energy from sunlight. If they are ever removed, these cells will eventually lose their ability to photosynthesize food without help from another organism - they have lost an essential organelle. Without the presence of this organelle, eukaryotes may not have been able to use sunlight as a mechanism for producing oxygen or making nutrients such as glucose available for consumption.
The organelle that may have allowed early eukaryotes to make food and produce oxygen is the plastid. The correct option is c.
What is plastid?The organelles that make up the cells of plants and algae are called plastids. These have chloroplasts, which enable them to absorb solar energy. These frequently include several kinds of pigments that can alter the color of the cell as well as pigments that are employed in photosynthesis.
These cells will eventually lose their capacity to photosynthesize food without the assistance of another creature if they are ever taken out since they have lost an important organelle.
Eukaryotes might not have been able to exploit sunlight to produce oxygen or make nutrients like glucose available for consumption without the presence of this organelle.
Therefore, the correct option is (c) the plastids.

how will climate change affect the habitat distribution for the baltimore oriole?
Climate change has a great effect on the habitat distribution of Baltimore orioles bird.
Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.
The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.
