Under the appropriate circumstances, sunlight entering the sea can penetrate around 1,000 meters into the ocean, although there is rarely much light beyond 200 meters.
The euphotic zone can stretch down to a depth of 80 meters (m) in crystal-clear tropical waters. The euphotic zone may be less than 10 m deep in places close to the poles since sunlight does not penetrate there as deeply. The euphotic zone may only be a few centimeters deep in murky, turbid water.
Light can only go so far below the ocean's surface due to the ocean's extreme depth. The water molecules scatter and absorb the light energy as it passes through them. Light is so dispersed at great depths that nothing is left to be detected.

15. the image below shows chromosomes in a human cell
i need answer a, b and c please!
This representation called as karyotype, the gender of the individual is male and this individual have the correct number of chromosomes.
What are chromosomes?Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.
Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
An individual's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order.
Present-day female humans have a single set of identical X chromosomes. Instead of a matched pair, male humans have one larger X and one smaller Y chromosome.
Thus, this image, known as a karyotype, shows that the person is male and has the appropriate amount of chromosomes.

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.
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.

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.

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.

D.
unsaturated fat
E.

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.
