Answer:
C) mitochondria.
Explanation:
All prokaryotic cells do not have membrane-bound organelles. In the case of mitochondria, however, it has a double membrane. It itself was originally a prokaryotic cell, but it evolved into an organelle.
A: Prokaryotic cells do glycolysis in which a net of 2 ATP's are produced, 2 NADHs are yielded, as well as 2 pyruvate.
B: Ribosomes are not membrane-bound and thus found in prokaryotse.
C: N/A.
D: Cytosol is most definitely found in prokaryotes; it's the jelly-like fluid that surrounds the organelles inside the cells.
E: Yes, prokaryotic cells have plasma membranes.

How would you describe the movement of the sun over 30 minutes?
Answers
Answer:
The Earth rotates from the west to east. The Sun does not rotate around the Earth, in Thirty minutes. the sun would appear to be in a different part of the sky, and that is because of the Earth's rotation.
Explanation:
Answer:
The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates. The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.

Answers
Answer: 1. independent , 2 . dependent
The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.
What is immune system?
The immune system protects our body from foreign invaders like bacteria, viruses, and fungi, and other toxins.
In general 2 types of the immune system observed in human body.
The innate immune system rapid inheritable response system consist major organs like skin, the eye's cornea, and the mucous membrane that lines the respiratory, gastrointestinal, and genitourinary tracts.
Secondly, the acquired immune system work with the innate system to make a special proteins named antibodies to protect our body from a specific invader.
Human immune system show variation in their production of immune components like cytokines play critical roles and it vary from person to person.
Hence, The immunity rate is an independent variable. The number of people affected by the disease is the dependent variable.

Answers
Answer: different number of neutrons and different mass numbers
Explanation:
The statements that describe isotopes of an element are:
Different numbers of neutrons.Different mass numbers.What is an isotope?An isotope is defined as varieties of atoms that have the same atomic number and therefore constitute the same element even though they have different mass numbers.
Characteristics of an isotope of an elementAtoms that are isotopes of each other have the same number of protons in the nucleus.They are found in the same place within the periodic table.Therefore, we can conclude that the isotopes of an element are atoms with the same atomic number but different mass numbers.

Insulin is a hormone that travels through the blood and helps regulate blood sugar levels. Which best describes how insulin travels in the blood?
in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells
Answers
Answer:
A:in the plasma
Explanation:
Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.
What is insulin?Insulin is a hormone that is released by β-cells of the pancreas. It controls the amount of glucose in our bodies. It converts glucose into glycogen and then this glycogen is stored in the liver, and whenever the glucose level reduces in the blood, then this stored glycogen is converted into glucose. It also helps in breaking fat and protein for energy.
Insulin is a very important hormone for the regulation of glucose in the blood. A deficiency of insulin occurs when the immune system attacks islets and it causes diabetes, in this disease blood sugar level increases
.
Insulin flows in the blood through plasma. Therefore, option A is correct.

Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient across the inner mitochondrial membrane generated by electron flow is used to synthesize ATP. B) Uncouplers dissipate the electrochemical gradient but electron transport continues without ATP production. C) Inhibitors disrupt electron flow as well as ATP synthesis. D) A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP. E) ATP synthesis occurs via simultaneous conformational changes in protein subunits containing catalytic sites.
Answers
Answer
D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP
Explanation:
Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.
Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.
The equation AU = Q - W describes which one of the following?
O A. Second law of thermodynamics
O B. Efficiency of a heat engine
O C. Work done by a gas
O D. First law of thermodynamics
SUBMI
Answers
Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
U is the internl energy of the system. ΔU is the change in U. Q refers to the total heat supplied into the system (include both addition and release of energy in the system). W is the net work done by the system.Hence, the correct option is D.
Answer:
Option D, First law of thermodynamics
Explanation:
The first law of thermodynamics states the following -
[tex]dU = Q-W[/tex]
where dU represents the Heat added to the System
Q represents the Change in Internal Energy OR net heat transfer OR sum of all heat transferred into and out of the system
W represents the Work done on the system
The first law of thermodynamics is based on the application of the conservation of energy principle to heat and thermodynamic.
hence, option D is correct
