A student attaches a rope to the handle of a chest loaded with few books , books while the other end of the rope is tied to a scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.
Answer:
B. As the mass of the chest increases, more force is required to pull it.
Explanation:
Option B is the correct that can be concluded from the data.
From the data, we can see that the mass of the chest is on the increase; it increases from 50, 75, 100, 150 and to 175. Also, in the force column, we can see an increment in the force also; from 0.25, 0.50, 1.15, 1.50 and to 1.70. So, from this data, we discover that as the mass increases, the force needed to pull it increases also.
Moreover, this is true even logically. If you want to pull an object with a heavy, more force will be required to pull it. Therefore, Option B is the correct answer.
30. How many DNA codes are used by life on Earth?
Answer:
That's how much information is stored in the DNA inside every human cell: the entire human genome. If you sort through the three billion letters that make up the human genome, you find some surprising things. Only about 1% of the three billion letters directly codes for proteins.
Explanation:
The DNA code contains 64 combinations that are named as codons. These codons are coding for the 20 amino acids, which the cell then puts together to form long amino acid chains, known as proteins.
What is DNA?DNA stands for deoxyribonucleic acid. It may be defined as a molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
There are 3.2 billion DNA codes that are used by life on Earth. Of the three billion genetic building blocks that make us living things, only a handful are uniquely ours. In fact, despite our differences on the outside, humans are 99.9% genetically similar to one another.
Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest 98.5 percent of DNA sequences is so-called “junk DNA” that scientists long thought useless.

In the Krebs Cycle of cellular respiration, pyruvate is used to make
A.oxygen
b. carbon dioxide
C water
D. More glucose
Answer:
b. carbon dioxide
Explanation:
This metabolic pathway is called the Krebs cycle after the scientist who first discovered it in 1937. The Krebs cycle is further broken down by pyruvic acid, obtained in the glycolysis process. The process proceeds in two stages. The first is the degree of decomposition of the bicarbonate residue.
The Krebs cycle is the main metabolic pathway for the breakdown of organic matter and the production of energy in the form of reduced coenzymes, which will then be incorporated into ATP.

What effect does the Earth spinning on its axis have on winds and currents?
The density of the water is increased causing the water to sink, forming deep ocean currents.
B) Global winds will move along a curved path and therefore cause ocean currents to curve.
Global winds will move along a straight path and will have no effect on ocean currents.
The moon's gravitational pull on the Earth is increased, causing water to move up the coast.
Answer:
B) Global winds will move along a curved path and therefore cause ocean currents to curve.
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
Basically, the effect of the Earth spinning on its axis have on winds and currents is that Global winds will move along a curved path and therefore cause ocean currents to curve. As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises. Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.
Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.
gynoceium with United carples is called as
Answer: Gynoceium with united Carples is know as SYNCARPOUS.
Explanation:
The vegetative organs of plants includes the stem, root and leaves. The stem which is the basic organ gives rise to other plant organs which includes the floral organs.
Floral organs are made up of:
--> sepals
--> petals
--> stamens
--> carpels
The carpel is the individual unit of the GYNOECIUM and has a stigma, style, and ovary. GYNOECIUM which is the female reproductive part of flowering plant can be monocarpous (when the carpels occurs in a single form), or apocarpous ( when there are multiple unfused carpels), or SYNCARPOUS (when there are multiple fused carpels).
Answer:
It is considered monocarpous if a gynoecium has a single carpet. If there are several distinct (free, unfused) carpets in a gynoecium, then it is apocarpal. If a gynoecium is "fused" into a single structure with several carpets, it is syncarpic.

as the hare population increases there is in increase in the lynx population explain why this occurs
Answer: The lynx population increases as the hare population increases because there are more prey for the lynx to eat. The Lynx population also increases because there is more food for them to eat. What does the increase in the lynx population lead to? It leads to a decrease in the hare population because the lynxes were eating the hares. What happens to the lynx population when the hare population goes up? Continued predation due to high populations of lynx and other predators increases the hare population decline. ... As hare numbers start to decline, lynx continue to eat well because they can easily catch the starving hares. When hares become scarce, lynx numbers also decline.
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
The changes in the population of one species can have a significant impact on the population of another species within the same ecosystem. Therefore, when hare population increases, there is in increase in the lynx population as well.
What is predator-prey cycle?A predator-prey cycle is a cycle where if the prey population increases in size, it leads to an increase in predator population size due to availability of more food.
The relationship between the hare and lynx populations is a predator-prey dynamics. When the hare population increases in size, the lynx population also increases due to availability of more food.
When there are more number of hares, the lynx hunts them more easily which causes an increase in lynx population. However, the increase in lynx population leads to more consumption of hares, that leads to decrease in the hare population. With fewer hares available, the lynx population then starts to decline leading to a cyclical pattern of population growth and decline.
Therefore, this type of relationship is a predator-prey cycle which describes changes in the population of one species can have a significant impact on the population of another species within the same ecosystem.

B. Homologous chromosomes line up along the equator of the cell.
C. Cytoplasm divides as cell prepares to become two new cells.
D. Daughter chromosomes move toward opposite poles of the cell.
Answer:
Daughter chromosomes move toward opposite poles of the cell.
Explanation:
Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.
CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.
When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.
