Answer:
The correct answer is - to make food for the seedling’s continued growth.
Explanation:
The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.
Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.

What is the positive aspect of GMO
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

Explanation:
There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)
Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.
Un objeto posee una energía cinética de 300J, este mismo se ubica a 4m de altura y su masa corresponde a 10Kg. ¿Cuál es su energía mecánica?
Answer: 692 J
Explanation:
La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.
La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos. Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.
La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.
La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):
Energía mecánica = Energía cinética + Energía potencial
Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)
Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)
Energía mecánica = 300 J + 392 J = 692 J
How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

Which of the following best describes a form of genetic drift in which the animal population is depleted, thereby reducing the population's genetic diversity?
A. bottleneck effect
B. disruptive selection
C. founder effect
D. gene flow
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population. So, the correct option is A.
What is the Bottleneck effect?The bottleneck effect occurs when population numbers are dramatically reduced as a result of natural disasters such as earthquakes, floods, and other natural disasters. The new population is composed of organisms that were able to survive the catastrophe whose allele frequency will be radically different from the original allele frequency.
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population.
Therefore, the correct option is A.

Answer:
Protect coastlines from storms, erosion and provide habitat.
Explanation:
Coral reefs protect coastlines from storms and erosion as well as provide a habitat for thousands of aquatic animals. These points rashid must include in his seminar. Coral reefs are very important for the marine ecosystem because it can save the soil from erosion and decreases the intensity of storms by acting just like barrier. It provides food as well as living place for many organisms so these point are very important to be included in the seminar.
