P2: How do genes determine an individual's traits? (click here to learn how to correctly check the box) Correctly choose one: Genes directly lead to traits. I Genes are random and don't lead to traits. Genes give organisms the ability to change their traits Genes are instructions for making protein molecules and protein molecules determine traits.
Answer:
genes are the basic sequence of DNA that controls the traits of an organisms.
Explanation:
genes have nucleotide sequences. these sequences are involved in transmission of characters from one generation to other. if their is an error occur in this sequence the new offspring will b dissimilar from parent in this secific character which chnaged.
central dogma is the basic process through which genes are controlling the traits. first step is transcriotion through which DNA or gene is transcribed into mRNA sequence. then the second step is translation in which mRNA is translated into protein. in this way by making proteins genes control the traits or functiong of a body.

Explain how our body systems work together to get oxygen into and around our body
PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
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.

Why is it important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high?
Answer:
These characteristics of water allows excellent working in the steam engines.
Explanation:
It is very important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high because due to large heat of vaporization, steam or vapors of water carries a huge amount of thermal energy. This large amount of heat energy is released when the steam condenses due to loss of kinetic energy. This property of water making it an excellent working fluid for heat engines as compared to any other fluid.

Why is it important that a healthy diet does not have a specific macromolecule composition?
Answer:
The correct answer is - each macromolecule has its own function and role in the body of an organism.
Explanation:
There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.
Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones. On other hand, carbohydrate provides energy for the cells, the transmission of the genetic information will be transferred by a nucleic acid. Fat also helps provide insulation, make lipid membranes.

What is the significance of a balanced diet for maintaining a healthy level of biomolecules in our cells and body to function disease-free?
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.

Answer:
Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

hich statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.
Answer:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.
