4. Genotypes-1/2 ww 1/2 ww = 1:1 ratio l Phenotypes-1/2 white 1/2 yellow-1:1 ratio
Answers
Answer:
2. Genotypes 1/2 Ww 1/2 ww 1:1 ratio | Phenotypes 1/2 white 1/2 yellow 1:1 ratio
Explanation:
This question involves a single gene coding for fruit color in squash. The allele for white color (W) is dominant over the allele for yellow color (w).
If a heterozygous white-fruited plant (Ww) is crossed with a yellow-fruited plant (ww), the following gamete combinations will be produced by each parent:
Ww- W and w
ww- w and w
Using these gametes in a punnet square (see attached image), offsprings with genotypes: Ww and ww will be produced in the ratio 1:1
(1/2) Ww will be phenotypically white-fruited
(1/2) ww will be phenotypically yellow-fruited
Hence, the seed offsprings of this cross will possess:
Genotypes 1/2 Ww, 1/2 ww in 1:1 ratio
Phenotypes 1/2 white, 1/2 yellow in 1:1 ratio

Explanation:
Obsessive-compulsive disorder (OCD) is a psychiatric condition that affects both children and adults. In the last years, it has been shown that genetic and environmental factors contribute to the etiology of this disease. By applying genetic mapping techniques, different genes were observed to be associated with OCD. Moreover, it has also been discovered that OCD is a trait that has a complex pattern of inheritance (i.e., it is a quantitative trait). However, it is important to note that more research is needed to fully understand how genetic factors influence OCD condition.

A mosquito somatic cell contains 6 chromosomes. This means that ____ different combinations of chromosomes are possible in the mosquito’s gametes as a result of the random alignment of chromosomes during meiosis.
Answers
Answer:
8
Explanation:
The law of independent assortment of genes as proposed by Gregor Mendel states that the alleles of a gene will separate into gametes independently of the alleles of another. This means that during the metaphase stage of meiosis I, line up randomly at the metaphase plate of the cell in order to be separated independently.
According to the question, a mosquito has 6 chromosomes in its somatic cells. This means that 2n (diploid) = 6 Chromosomes. Hence, after meiosis, its gametes (n) will contain 3 chromosomes each. To find the number of different combinations of chromosomes possible in the mosquito’s gametes, we use 2^n where n represents the number of haploid chromosomes.
Hence, if 3 chromosomes are possible in a mosquito's gametes, 2^3 = 8 different combinations of chromosomes are possible in the gametes as a result of random orientation during the metaphase of meiosis.

a. This cell function is to produce steroids
b. There would need to be fatty acids and glycerol in the cytoplasm
c. The product made in this cell would be exported from the cell
d. There are moderate energy demands in this cell
e. There would need to be amino acid in the cytoplasm of cell
Answers
Answer: Option D.
There are moderate energy demands in this cell
Explanation:
The rough endoplasmic recticulum is an organelles in the cell that has many RIBOSOMES. These RIBOSOMES are important for the synthesis of proteins. And the Golgi apparathus is responsible for protein modifications into different functions after receiving it from rough endoplasmic recticulum
But without secretory vessicles, Amino acids will not be transported in the cell. Without it been transported, there is moderate demands in the cell because energy is required to transport and modify proteins by the secretory vessicles. Mitochondria is the power House of the cell or it produce energy, moderate number of mitochondria means that moderate or few energy will be supply to the cell organelles for proper functioning and processes because energy is required for cellular activities.

O The electric force decreases because the distance has a direct relationship to the force.
Answers
Answer:
C. The electric force decreases because the distance has an indirect relationship to the force.
Explanation:
The electric force decreases because the distance has an indirect relationship to the force. Therefore, the correct statement is option C.
What happens when the distance between two charged items grows?As the distance between two charged items grows, the electric force between them diminishes. Because of the inverse square law, which states that the force of attraction or repulsion between two charged objects diminishes as the square of the distance between them rises, this is the case.
The force exerted by two charged objects will be decreased to one-fourth of its initial strength if the distance between them doubles. Similar to this, if the distance is quadrupled, the force loses 90 percent of its initial power. As a result, the electric force between charged objects lessens with increasing distance.
The farther the distance between charged objects, the weaker the electric force between them becomes due to the decrease in the strength of the electric field. This relationship follows an inverse square law.
Therefore, electric force decreases because the distance has an indirect relationship to the force.

Explain the process of breathing begin with inhalation and describe the route that the air takes to the lungs and what happens when the air reaches the lungs include in your description the terms mouth nose pharynx larynx trachea bronchi lungs alveoli carbon dioxide oxygen and capillaries..... PLEASE HELP PLEASE
Answers
Answer:
Please find the detailed explanation below
Explanation:
The breathing process is the process of breathing in, also called inhalation and breathing out, also called exhalation. Inhalation and exhalation are important processes for a smooth respiratory experience.
Air (containing oxygen) from our external environment enter our body system via our MOUTH or NOSE. The air then passes from the PHARYNX into the LARYNX or voice box, which connects into the TRACHEA or wind pipe, which conveys the air into the lungs via its branched tubes called BRONCHI. These pipes that air passes through in order to reach the lungs are generally called AIR WAYS.
Inhalation (breathing in) involves the taking in of air into the LUNGS (main organ of respiration). It occurs when the diaphragm (muscle separating the thorax from abdomen) contracts and moves downward towards the abdomen. This allows the lungs to expand, allowing air to enter into the lungs via the NOSE or MOUTH down the TRACHEA or windpipe.
As soon as air reaches the lungs, the air passes through the bronchi (tubular branches of the trachea) into the ALVEOLI or air sacs. The delivery of oxygen in the inhaled air is carried out in the CAPILLARIES (a blood vessel that carries blood) that surrounds the alveoli. This alveoli conveys oxygen from the lungs into the bloodstream and carbon dioxide out of the bloodstream into the lungs (a process called GAS EXCHANGE).
Breathing out or exhalation of the carbon dioxide in the lungs (waste product of respiration) occurs when the diaphragm relaxes and moves upward, causing the lungs to deflate as the carbon dioxide is released through the trachea into the mouth or nose where it leaves the body system.

What makes ribosomal RNA useful as a molecular clock? (2 points) A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations. Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. A slow mutation rate makes it useful for determining evolutionary relationships between ancient species. It is only found in select organisms, making it easier to compare relationships between species that have it.
Answers
Answer:
The correct statement is that a slow mutation rate makes it useful for determining evolutionary relationships between ancient species.
Explanation:
The rRNA or ribosomal RNA has an application as a molecular clock because of many factors. It exhibits a very slow mutation rate, that is, around one million years because of which it stays highly conserved in all the organisms. In the ribosomal RNAs of two organisms, the degree of mutations can be associated directly with the time they were originated in the past.
In supplementation, it possesses essential biological function because of which it can be witnessed in almost all the species.

Answers
Answer:

Explanation:
In this paper, the author stated that environmental factors have been fundamental for the emergence of adaptive traits during human evolution. In consequence, Dr. Potts explained how particular environmental factors and habitats might have shaped human evolution. For example, it has been hypothesized that dry savanna vegetation might have been a key environmental factor associated to the emergence of human traits including, among others, bipedality, making of tools from stones, the development of human brains, etc. In order to prove this hypothesis, the author recorded environmental data from different regions in Africa (Olorgesailie, Olduvai, Turkana, Zhoukoudian, etc), where it is believed that first hominids evolved about 6-8 million years ago.

Why does deleting just one nucleotide cause a dramatic change in the amino acid sequence produced by translation
Answers
Answer:
The deletion changes the genetic code.
Explanation:
The sequence of nucleotides determines the order of amino acids in a protein, the order of amino acids determines the shape and the shape determines the function. A very good example of one misplaced nucleotide having tremendous effects is sickle cell disease, where thymine is replaced with adenine(CAC instead of CTC). It means that glutamic acid is replaced with valine. This alters the shape of the protein(Beta chain of hemoglobin). So the red blood cells are deformed and carry a lot less oxygen leading to a lot of symptoms just because of one misplaced letter.
