As you walk to physics class, you start out at a speed of 2 m/s, for a time of 120 seconds (you’re really excited to get to class). Then you see your friend and slow down to a speed of 0.5m/s for 30 seconds. You stop at your locker for 40 seconds (a speed of 0 m/s). You realize that you are about to be late so you hurry to class at a speed of 1 m/s and get to class just as the bell rings (4 minutes after your trip started). How far did you travel total?
Answer:
The total travelled distance is [tex]51065 \mathrm{~m}[/tex]
Explanation:
• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.
• Calculate total speed;
[tex]\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}[/tex]
• Calculate total time taken;
[tex]\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}[/tex]
• To find total travelled distance, use the formula
[tex]\text { Distance }=\text { Speed } \times \text { Time }[/tex]
[tex]\mathrm{d} &=3.5 \times 14590 \\[/tex]
[tex]&=51065 \mathrm{~m}[/tex]

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do you think it is important to conserve the environment.
WILL NAME BRAINLIST!
Answer:
Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.
-These are some examples of how we can conserve the environment:
Recycle your rubbish and participate in or help organize recycling campaigns.
Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).
Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).
Swap toys, movies, and books instead of buying new ones.
Donate, recycle, and repair electronic devices (see how here).
Use less water when brushing teeth, taking a shower, or washing the dishes.
Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.
Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.
Use less paper by not printing unnecessary things and reading e-books.
Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.
Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.
Do not waste food and try to buy food that is grown locally and in season.

During the process of photosynthesis, energy from the Sun is converted into A) chemical energy in the bonds of inorganic molecules B) chemical energy in the bonds of organic molecules like glucose C) enzymes used to produce inorganic molecules D) enzymes used to produce organic molecules
Answer:
b
Explanation:
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The correct option is:
Option B. chemical energy in the bonds of organic molecules like glucose
The process of photosynthesis involves:
Photosynthesis is carried out by plants. The leaves are the primary site for photosynthesis. The chloroplasts present in the plant cells are primarily involved in photosynthesis. Photosynthesis involves the capturing of light energy and storing it in the form of bonds of organic molecules like glucose and starch. The process involves carbon dioxide, water, sunlight, and green pigment chlorophyll to carry out photosynthesis. The products of the process are oxygen and sugar molecules holding the energy.
Thus, the correct answer is option B.

A scientist warms a chemical to 385 K, and the chemical begins to boil. How much higher is this boiling point of the chemical
than the boiling point of water?
12K is the boiling point of the chemical .
The boiling point of any liquid changes to the applied pressure the normal boiling point is the temperature at which the vapor pressure is equal to the standard sea-level atmospheric pressure .At sea level, water boils at 100° C (212° F).The boiling point of a liquid is the temperature at which its vapor pressure is equivalent to the pressure of the gas above it.
Boiling point is used to identify and classify a given compound. A liquid boils when its vapour pressure is equal to the atmospheric pressure. Vapour pressure is also defined by the kinetic energy of a molecule. Kinetic energy is dependent on the temperature, mass and velocity of a molecule.

Winter wheat is planted in the early autumn, grows over the winter when the weather
is colder, and is harvested in the spring. As the temperature drops, the composition of
the cell membrane of winter wheat changes. Unsaturated fatty acids replace saturated
fatty acids in the phospholipids of the membrane. Why is this a suitable adaptation?
Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.
Explanation:
Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.
What are unsaturated fatty acids?Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.
Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

spines provide protection from predators. Which of the following statements best explains why cactus plants
evolved to have these traits?
Answer:
C
Explanation:

Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
