Pulling and digging are the two examples of Mechanical weed control while on the other hand, herbicides such as Metribuzin and 2,4-dichlorophenoxyacetic acid (2,4-D) are the two examples of Chemical Weed Control. Herbicide is the most effective and quick method used for weed control.
What is a dominant allele?
A. In a heterozygous individual, the allele that determines the phenotype
B. An allele that will only have an affect on phenotype in a haploid organism; otherwise its presence will be masked
C. An allele that is very prevalent in a population
D. An allele that totally beats up on a recessive allele
E. An allele that has no noticeable affect on an organism's phenotype
Answer:
A. In a heterozygous individual, the allele that determines the phenotype
Explanation:
The dominant allele completely hides the expression of the recessive allele. This occurs in cases of Autosomal dominant inheritance. Even when both dominant and recessive alleles are present in the genotype, this is the heterozygous state, only the dominant trait will be expressed. Only one dominant allele is enough to express the dominant phenotype.

Which food component is indigestible by the body?
A.
complex carbohydrate
B.
fiber
C.
protein
D.
unsaturated fat
E.
trans fat
Reset Next
Answer:
Fiber
Explanation:
Fiber is one kind of carbohydrate which is indigestible by the body. Fiber is a part of plant foods which is not digestible for our body.
Fiber is the food component that is indigestible by the body. Therefore, option (B) is correct.
Fiber is a type of carbohydrate found in plant-based foods that the human body cannot digest or absorb. It passes through the digestive system relatively intact and provides several health benefits. There are two types of dietary fiber: soluble and insoluble.
Soluble fiber dissolves in water to form a gel-like substance in the digestive system, which can help lower cholesterol levels, regulate blood sugar, and promote feelings of fullness. Examples of foods that are high in soluble fiber include oat bran, beans, apples, and citrus fruits.
Insoluble fiber, on the other hand, does not dissolve in water and helps to add bulk to stool, promoting regular bowel movements and preventing constipation. It also helps to keep the digestive system healthy by feeding beneficial gut bacteria. Examples of foods that are high in insoluble fiber include whole grains, nuts, seeds, and dark leafy greens.
Including a variety of high-fiber foods in the diet can have numerous health benefits, including improved digestion, lowered risk of heart disease, and better weight management.

HELP!!!! FAST!!!! 20 POINTS!!!! You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal
mass (3,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know:
• Truck 1 started from rest at the top of a 22-meter hill and coasted toward the intersection.
.
Truck 2 was on a flat stretch of road at the bottom of the hill directly in front of Truck 1.
At the bottom of the hill, Truck 1 was going 20 m/s; Truck 2 was going 35 m/s.
.
There were no skid marks left by Truck 2. The collision occurred at the stop sign where Truck 2 had
stopped
• After the collision, both trucks moved together in the same direction at 10 m/s before slowly rolling
to a stop.
You must now push Truck 2, using 1,000 N of force, 8 meters off to the side of the road so no one
else gets hurt.
1. How much work was done to bring truck 2 to a stop? 2. If tuck 2 came to a stop In 15 seconds, how much power (in watts) did it take to stop truck 2 at the sign by applying force to the brakes? 3. What is the final combined momentum of the trucks right after the accident? 4. Assuming that there are no other no conservation forces involved, what impulse was given to each truck during the collision? A. Truck 1: B. Truck 2:
Answer:
1) Kinetic energy of the truck 1 is 600,000 joules.
Kinetic energy of the truck 2 is 1,837,500 joules.
2 a)Potential energy of truck 1 is 646,800 Joules.
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.
Step-by-step explanation:
Mass of the truck 1 and truck 2,m = 3000 kg
Velocity of the truck 1, = = 20 m./s
Velocity of the truck 2, = 35 m./s
1. Kinetic energy of the truck 1:
Kinetic energy of the truck 2:
2.a) Energy loose by the truck 1:
Initial height of the truck on the hill = 22 m
At that height potential energy will be maximum:
Potential energy of truck 1 at that height =
b) Energy lost by the truck 1 just got converted into heat and sound energy during the collision.

How can one use a community in teaching the concept "Safe use of agro-chemicals" to grade six level?
Answer:
A community can be divided into groups, where each group can present the correct ways to use agro-chemicals safely in different types of activity.
Explanation:
Using a community can be very helpful in teaching the safe use of agrochemicals. This is because, as a community usually has a large number of people, these people can be divided into small groups that will serve as small workshop rooms. Within these groups, the different ways to use agro-chemicals in a safe way, both for the applicator and for the environment, will be shown. Information on the composition of agrochemicals, first aid in case of accidents with the use of these products, among other things, can also be presented.

If both maize and teosinte are grown in the wild, which species is more likely to proliferate? Why?
Answer:
he maize is more likely to proliferate because of the human effect.
Explanation:
If both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.
What are maize and teosinte?Maize and teosinte are both members of the grass family, but they differ in several important ways. Maize, also known as corn, is a domesticated crop that has been selectively bred over thousands of years to produce larger, more desirable ears for human consumption. Maize has a much larger ear size than teosinte, and its kernels are also larger and more closely packed together.
Hence, if both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.

Un fluido es todo cuerpo que tiene la propiedad de fluir, y carece de rigidez y elasticidad, y en consecuencia cede inmediatamente a cualquier fuerza tendente a alterar su forma y adoptando así la forma del recipiente que lo contiene. Los fluidos pueden ser líquidos o gases según la diferente intensidad de las fuerzas de cohesión existentes entre sus moléculas. Seleccione una: Verdadero Falso
Answer:
True.
Explanation:
Yes, fluids can be liquids or gases depending on the different intensity of the cohesion forces that exists between their molecules because these cohesive forces allows the molecules to attach to one another that leads to their state of matter. Cohesion forces such as hydrogen bonding and van der Waals forces are responsible for the bulk property of liquids that resisting separation from one another so due to these bonding, the molecules attach to one another on the basis of strong bonding between molecules.
A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material. Function of Tertiary Consumers
Answer:
The function of tertiary consumers is to keep the population of primary and secondary consumers under control, in addition to serving as food for quarternary consumers.
Explanation:
As stated in the question above, tertiary consumers are those who feed on secondary and primary consumers within the food chain. They represent a very important trophic level, in addition to allowing the transfer of energy between living beings to flow normally, they manage to control the populations of primary and secondary consumers, which keep nature in balance. In addition, they serve as food for other consumers, the quarternarios consumers.
