Explanation:
The catalyst decreases the activation energy needed.
Catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.
What is catalyst?Catalyst is defined as a material that allows a chemical process to happen under new circumstances or at a typically faster rate.
It can also be defined as an additive ingredient that can speed up a reaction without being consumed during the process.
There are basically four types of catalyst.
Homogenous catalystHeterogenous catalystHeterogenized homogenous catalystBiocatalystNickel, When making margarine out of palm oil, Ni is employed. In the Haber process, iron (Fe) is employed etc. are some of the example of catalyst.

(PLS HELP DUE IN 5 MINS!) The pteropoda, or “sea butterfly”, is a tiny sea creature about the size of a small pea. Pteropoda are eaten by organisms ranging in size from tiny krill to whales. They are a major food source for the North Pacific juvenile. Their shells are made up of calcium carbonate. The photo provided is the shell of a pteropoda. The shell can dissolve within a 45 day period. What can one infer about what is causing the shell of the pteropoda to disappear while in a marine environment?
a) Carbon monoxide (CO) is being released by natural systems. Oceans are absorbing this excess of CO and the pH within the oceans is increasing.
b) Methane (CH4 is being released too quickly from burning of fossil fuels. Oceans are lowering their pH and ocean acidification occurs.
c) Natural sources are releasing an excess of CO2 to the oceans. The marine photosynthetic organisms are emitting too much oxygen. This is return is causing ocean acidification.
d) The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.
Answer:
The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.

Specialized structures that work together inside a cell are called __________. Choose the correct answer.
nuclei
organelles
eukaryotes
prokaryotes
An organelle is a specialized subnet that is found inside the cells has been programmed to perform a specialized type of specific cell functions.
These are identified under microscopy and include the structures that make up the inner endomembrane system.
The organelles may be in the form of the cell wall, membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, flagellum, and nucleus. Most of them are found in eukaryotes. They are organs like the heart, liver, stomach, and kidneys. All are essential functions to keep the organisms alive.Hence the specialized structures that work together inside a cell are called organelles.

Cellular membranes enclose a cell and its contents from its environment. Establish which of the
following comprises cellular membranes.
A. Lipids
B. RNA
C. DNA
D. Microsphere
Answer:
The function of segregating the interior of the cell enclosure to the outside is known to occur by the function of the plasma membrane. These molecules comprising the plasma membrane is none other than lipids. Highly enriched hydrophobic tails of lipids interact with other lipids in a typical bilayer arrangement to regulate and control gene expressive Molecular and other crucial ions from moving in.
A small prokaryotic cell is approximately a rectangular prism with a width of 2uM, length of 4uM, and depth of 3 uM. What is the volume of the cell.
Answer:
24μm³
Explanation:
According to this question, a cell, which is said to have the shape of a rectangular prism have the following dimensions:
Length = 4μm
Width = 2μm
Depth = 3μm
Since the cell has the shape of a rectangular prism, the formula for volume of rectangular prism, which is V = l × b × d
Volume of the cell = 4μm × 4
3μm × 2μm
= 24μm³

Answer:
First square = [-]
Second square = [+]
Third square = H
Forth square = O
Fifth square = H
Explanation:
Labeling the diagram to show how hydrogen bonds form between water molecules:
1st box = ( - )2nd box = ( + )3rd box = ( H )4th box = ( O )5th box = ( H )Water ( [tex]H_{2}O[/tex] ) is an odorless , tasteless...... chemical compound formed by the bonding of two ( 2 )hydrogen atoms and an oxygen atom. the bonding between the hydrogen and oxygen atoms is carried through covalent bonding ( sharing of electrons between atoms ). indicating how hydrogen bonds.

Imagine that you are a scientist who has discovered a new object. You want to find out if the object is biotic or abiotic. You observe several characteristics about the new object. Which of these characteristics would tell you that the object is abiotic, or not alive?(1 point)
The object cannot create energy.
The object has a crystalline structure.
The object can mutate.
The object responds to stimuli.
Answer:
the answer is the object cannot create energy
Explanation:
i just got it right on my quick check
The characteristic that would tell if an object is abiotic or nonliving is if the object cannot create energy.
The capacity to create energy for the normal functioning of the body is one of the key characteristics of living organisms. This energy is usually gotten from the breakdown of food materials through a process known as respiration.
Respiration could be in the presence (aerobic) or absence (anaerobic) of oxygen but the ultimate end is to generate energy, usually in the form of ATP, for metabolism.
Thus, any object that lacks the capacity to carry out respiration cannot be considered to be living or biotic.
