A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self- fertilize. The following data were obtained:
F1 generation: All offspring are disease-sensitive and herbicide-resistant
F2 generation: 157 disease-sensitive, herbicide-resistant
57 disease-sensitive, herbicide-sensitive
54 disease-resistant, herbicide-resistant
20 disease-resistant, herbicide-sensitive

A plant growing toward the sun is an example of
Answer:
phototropism
Explanation:
Answer:
Hi Noya here! (◕ᴥ◕)
Explanation:
Phototropism is the term that describes the growth of a plant toward any light source. School-age children often demonstrate this principle by showing how a newly sprouted seed, for example, leans in the direction of a nearby light bulb. Heliotropism is the process that describes how a plant specifically tracks the sun’s movement across the sky.

what are the sections on chromosomes? genes or DNA?
Answer:
genes
Explanation:dna whatttt
Answer:
Each section of a chromosome that contains the code for the production of a particular protein is called a gene . Each chromosome is made from a single molecule of DNA, but when a cell is ready to divide, the DNA copies itself, then coils and condenses to form the chromosomes that we see in micrographs .

A.Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances
against a warm air mass.
B.Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is
trapped between two cold air masses.
C.Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold
air mass moves over a warm air mass.
D.Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when
a warm air mass moves over a cold air mass.
Answer: Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses.

Which of these transport processes is the major means by which Na+ is transported across the membrane of neurons? Why?
A) both II and III because the activity of the neuron varies
B) I because Na+ is so small it can freely diffuse into the cell
C) III because Na+ is actively transported out of a neuron to maintain extracellular concentration
D) II because Na+ is charged and cannot cross the hydrophobic interior space of the cell membrane
Answer:
i think it’s C
Explanation:
I. is diffusion
II. is facilitated diffusion
III. is active transport
the third diagram makes most sense to me
Transport processes is the major means by which Na+ is transported across the membrane of neurons,I because Na+ is so small it can freely diffuse into the cell.

there are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitamins, and minerals. most foods or ingredients include more than one of the six basic nutrients. for example, although most people usually think of corn as containing carbohydrates, it is important to remember that a kernel of corn contains all six basic nutrients.
Match the words to the appropriate blanks in the sentences.
_______nutrients be synthesized by the human body, but are required for optimal functioning. Therefore. they must be Obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to _________ which you consume in small quantities
_________ can develop very quickly when exercising in hot/humid weather conditions.
_________are also called 'body builders" due to their function within the body________ are the building blocks of proteins.
1. glucose and fructose
2. essential
3. incomplete
4. proteins
5. fat soluble
6. plant
7. amino acids
8.saturated fats
9. micronutrients
10. dehydration
Answer:
Essential nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to micronutrients which you consume in small quantities
Dehydration can develop very quickly when exercising in hot/humid weather conditions.
Proteins are also called 'bodybuilders" due to their function within the body. Amino acids are the building blocks of proteins.
Explanation:
Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.
Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.

Looking at the following organisms and their diets, place them into a food chain. Make sure you have arrows that show the correct flow of energy.
Aardvark: omnivore diet
Ant: herbivore diet
Grass: autotroph
Hyena: carnivore diet
Answer:
Grass > Ant > Aardvark > Hyena
Explanation:
The grass is autotrophic, which means it can produce its own food It does so using water, carbon dioxide, and light energy from the sun. The organisms in this food chain rely on other organisms for food.
The ant is a herbivore that consumes the grass for energy. The aardvark consumes both plants and animals (omnivore), so it can consume the ants. The hyena is a carnivore, meaning it only eats animals, such as the aardvark.

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?
The trend in the corn productivity shows an increase from the year 1988 to 2008.
This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

Reliability and probability in forensic tests are important. When you look at matching a paint chip to a specific car, you are working to increase the probability that the right car matching your paint chip evidence will be found. Reliability means you have practiced and applied the correct procedures and processes for all your evidence testing, and you know you can trust the results. Some forensic tests are more reliable than others, and the best type of test or tests to use will usually depend on the kind of evidence that is present. If all types of evidence were present at a crime scene, which type of test would you choose based on its reliability and probability of accuracy? Identify which test you would choose and provide a detailed argument as to why you feel it has a high level of reliability in comparison to other types of evidence. Your answer should be at least two paragraphs in length and should include solid arguments for your choice. There is no wrong choice, just be sure to provide a convincing argument.
