you run 100m in 25s. If you later run the same distance in less time, explain if your speed increases or decreases
Answers
Answer : If we later run the same distance in less time, the speed will be increases.
Explanation :
First we have to calculate the speed.
Formula used :
Given:
Distance = 100 m
Time = 25 s
Now put all the given values in the above formula, we get:
From the formula we conclude that, the there is an inverse relationship between speed and time at constant distance.
As, the time increases, the speed will be decreases and vice-verse.
As per question, if we later run the same distance in less time, the speed will be increases.
Hence, if we later run the same distance in less time, the speed will be increases.

Mitosis occurs in the somatic cell, it is an equational division, mitosis is required for the repair and growth of the cell and organism consequently.
While meiosis occurs in gametes or germ cell, it is a reductional division, meiosis is responsible for the formation of sex cells as sperm and eggs in the organism.
Both mitosis and meiosis are responsible for splitting the nucleus and DNA and these are passed on to the two daughter cells formed.
Explanation:
Mitosis is the process of cell division in which the cell divides and each cell is identical to the parent cell in the context of DNA and its nature There are four phases of DNA as Prophase, metaphase, anaphase and telophase. The daughter cells formed, have diploid (2n) number of chromosomes.
While meiosis is the process of cell division in germ cells which start with one cell and ends in 4 haploid cells. Meiosis is completed in two steps as meiosis 1 and meiosis 2.

A typical carbon atom can form four covalent bonds. It attains stability by sharing its four outer shell electrons with other atoms via covalent bonds, a process exemplified by methane.
Explanation:
A typical carbon atom can form four covalent bonds. This is because carbon has four electrons in its outer shell and needs to gain four more electrons to attain stability, which it does by forming covalent bonds with other atoms. A covalent bond is formed when two atoms share electrons. A classic example can be seen in methane (CH4), where one carbon atom forms four covalent bonds with four hydrogen atoms.

Chemical breakdown processes in cells directly involve enzymes, which facilitate chemical reactions by lowering activation energy. Examples include cellular respiration and digestion.
Explanation:
All chemical breakdown processes in cells directly involve enzymes, which are specialized proteins that facilitate chemical reactions. Enzymes work by lowering the activation energy required for a reaction to occur, allowing chemical breakdown to happen more efficiently. Some common examples of chemical breakdown processes in cells include cellular respiration, where glucose is broken down to release energy, and digestion, where food molecules are broken down into smaller units for absorption.

Chemical breakdown processes in cells directly involve catabolic reactions, which form part of the cell's metabolism. Complex molecules are broken down into simpler ones, releasing energy. An understanding of this process is vital for understanding how cells, and biological systems more generally, function.
Explanation:
All chemical breakdown processes in cells directly involve a type of biochemical reaction known as catabolism. This is part of the cell's metabolism, which includes all chemical reactions that occur within the cell. Catabolism is the process through which complex molecules are broken down into simpler ones, with an accompanying release of energy.
For example, complex carbohydrates from food are broken down into simpler glucose units through catabolism. Furthermore, catabolic reactions also involve the breakdown of Adenosine triphosphate (ATP), the primary energy currency of cells. The energy released from catabolic processes drives different cellular activities and reactions.
The balance between catabolic and anabolic (building up) processes allows cells to harvest and efficiently use the energy necessary for their functioning. Therefore, energy is central to these cellular chemical processes. To understand any biological system, including cells and their biochemistry, it is crucial to understand how energy flows and is utilized within these systems.
