Answer:
[tex]\boxed {\boxed {\sf 12 \ m/s^2}}[/tex]
Explanation:
Force is the product of mass and acceleration.
[tex]F=ma[/tex]
The mass is 25 kilograms and the force is 300 Newtons, but we should convert the units to make the problem easier later.
1 Newton is equal to 1 kilogram meter per square second. The force of 300 N is equal to 300 kg*m/s²Substitute the known values in for the variables ( F and m).
[tex]300 \ kg*m/s^2= (25 \ kg) a[/tex]
Since we are solving for a, we must isolate the variable. a is being multiplied by 25 kilograms and the inverse of multiplication is division. Divide both sides by 25 kg.
[tex]\frac{ 300 \ kg*m/s^2}{25 \ kg}= \frac{(25 \ kg) a}{25 \ kg}[/tex]
[tex]\frac{ 300 \ kg*m/s^2}{25 \ kg}= a[/tex]
The kilograms will cancel out (hence our earlier unit conversion).
[tex]12 \ m/s^2=a[/tex]
The acceleration is 12 meters per square second.

The honeybee has 32 chromosomes in their somatic cells. They undergo meiosis but can
produce offspring drones without fertilization. How many chromosomes does the drone have?
What does this mean for the drone?
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.

Answer:
C. a single strand and contains uracil.
Explanation:
DNA has 4 bases: adenine, cytosine, guanine, and thymine and is double stranded while RNA is one stranded and instead of thymine, it uses uracil.

What is Cordyceps?
A fungus called cordyceps is found in China's high mountain regions and feeds on specific caterpillars. It is occasionally employed as medication.
The majority of supplements use lab-made cordyceps. Despite the fact that cordyceps is occasionally referred to as a mushroom, the form of cordyceps created in a lab does not grow a mushroom.
By stimulating immune system cells and certain molecules, cordyceps may enhance immunity. In especially with lung or skin malignancies, it may also aid in the fight against cancer cells and reduce tumor size. Natural cordyceps can be pricey and difficult to get.
Therefore, They help regulate the population of the arthropods in the jungle.

Explain how the genetic disease called Sickle Cell Anemia is more prevalent in African- Americans compared to other races because of the Malaria Disease.
Answer:
Explanation:
This is because sickle cell disease is common in malaria dorminated area because their traits confers resistance to malaria. The red blood cells, which contain abnormal hemoglobin become sickle in shape after it has been affected by malaria parasite. Therefore, most American that have African ancestry are at high risk of
the disease because the African ancestry are carriers if this gene and are inherited by the Americans.
What are the 2 laws Mendel came up with?

#CARRY ON LEARNINGOkazaki fragments are formed on which strand?
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.

a)energy
b)support
c)information
d)matter
Answer:
C
Explanation:
information
The one that is the most significant contribution DNA makes to the formation of an organism is information. The correct option is C.
What is genetic information?Information about an individual's genetic tests and the genetic tests of an individual's family members.
Also information about the manifestation of a disease or disorder in an individual's family members, is included in genetic information (i.e. family medical history).
Genetic information includes your genetic tests as well as the genetic tests of your family members. Genetic information also includes any disease, disorder, or condition that your family members have.
All of the proteins that an organism will ever synthesize are encoded in the genetic information stored in its DNA. DNA is found in the cell nucleus of eucaryotes.
A DNA molecule is made up of two complementary nucleotide chains. The Structure of DNA Provides a Heredity Mechanism.
Thus, the correct option is C.

Which of the following explains the role of plants in the carbon cycle?*
(1 Point)
Plants transfer oxygen and carbohydrates in the biosphere to carbon dioxide in the atmosphere.
Plants transport carbon dioxide in the atmosphere to groundwater.
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Plants transfer oxygen in the atmosphere to fossil fuels.
Answer:
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Explanation:
Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.
However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).
