Colorblind is a recessive trait (n) so the fraction is 2/4
If a colorblind female (XnXn) and a normal male (XNY) have a son, then the chances he would be colorblind is 50%.
Inheritance linked to the X chromosome is different from the inheritance of autonomic chromosomes because males inherit only one X chromosome.Conversely, females inherit two X chromosomes, thereby resembling mendelian autonomic inheritance.In the Punnet square:Xn Xn

Explanation:
I took the test
The product of photosynthesis are option (C) glucose and (D) oxygen gas.
What is photosynthesis?The energy from light is converted into the form of chemical energy through a process known as photosynthesis, which is utilized by living creatures like plants. Through a process known as cellular respiration, this chemical energy can eventually be converted into usable fuel that can be utilized to power the activities of the organism.
It is standard practice to write the equation that describes the process of photosynthesis as follows: 6CO2 + 6H2O gives C6H12O6 + 6O2.
This suggests that chlorophyll, which takes in light energy and converts it into chemical energy, is responsible for the transformation of the reactants, which are comprised of six molecules of carbon dioxide and six molecules of water, into the products, which are one molecule of sugar and six molecules of oxygen.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
Answers
B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.
What is non-specific immune response?Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.
Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.

What is the significance of a balanced diet for maintaining a healthy level of biomolecules in our cells and body to function disease-free?
Answers
Answer:
A balanced diet makes our body work in the best possible way. Both the lack of food and the excess of them is detrimental to health, therefore the appropriate amounts must be consumed for each individual. It meets our basic physiological needs and reduces the risk of disease.
Explanation:
Food is the set of processes that allows organisms to use and transform nutrients to stay alive. A balanced diet will largely depend on the human being leading a healthy life. The foods that are consumed each day must have adequate amounts of both the macronutrients (carbohydrates, proteins, lipids), as well as the micronutrients (minerals and vitamins) and water, which are bioavailable that the consumed diet must contain, in order to satisfy the requirements physiological of each individual. In addition to covering individual variability, for some nutrients an additional amount is added to establish a margin of safety. Complying with the appropriate amounts avoids and prevents overweight, obesity, as well as chronic degenerative diseases such as diabetes mellitus, dyslipidemias, cardiovascular diseases, cerebrovascular disease, etc. and in turn helps the person to look and feel better, increasing physical and mental performance. Poor nutrition means neglecting some nutrients or overdoing others. This is the main factor that promotes progressive weight gain and obesity according to experts.

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GgKk. What possible gametes can the plant
produce?
O A. GK, GG, KK, kK
OB. GK, Gk
Oc. GK, Gk, gk, gk
OD. GK, gk
Answers
Answer:
The options are incomplete, however, the question can still be answered based on general understanding. The possible gametes are:
GK, Gk, gK and gk
Explanation:
This question involved two different genes coding for leaf color and stem length respectively. In the first gene, the allele for green color is 'G' while the allele for yellow color is 'g'. In the second gene, the allele for long stem is 'K' while the allele for short stem is 'k'.
According to this question, a scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GgKk. Based on Mendel's law of SEGREGATION, this plant with genotype: GgKk will undergo meiosis where the alleles of each gene will separate into possible gametes as follows:
GK, Gk, gK and gk
Note that, only one allele of each gene is present in each gamete.

An athlete throws the javelin 212 m. The average speed of the javelin was 15 m/s. How long was the javelin in the air?
Answers
Answer:
The correct answer is - 14.133 seconds.
Explanation:
The time that the javelin took in the air before landing after the 212 m throw can be calculated by simple distance and velocity formulas which say that the speed of an object is equal to the distance traveled by the object in unit time.
Given:
Speed or s = 15 m/s
Distance or d = 212 m
Then, the time or t =?
Solution:
By the formula, s = d/t
or t = d/s
t = 212/15
t = 14.1333
thus, the correct answer is - javelin was in the air for 14.1333 seconds.

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?
Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.
Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.
The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.
The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.
Answers
Answer:
breeding with and altering the population of wild salmon
the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects
there is a rainforest in BC that's survival relies on the nutrients that salmon bring when they spawn and die

Which is larger, 40 centimeters or 670 millimeters?
Answers
Answer:
670 Millimeters
Explanation:
1 Millimeter = 0.1 Centimeter
670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.
What is a millimetre?It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.
It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.
The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.
Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.
Therefore, 670 mm is 67 cm which is greater than 40 cm.

Answers
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
