Which of the following is/are TRUE about a cell’s plasma membrane? (CHOOSE ALL THAT APPLY.)
Question 3 options:
Plant cells have a cell wall instead of a plasma membrane.
Proteins are embedded in the plasma membrane and contribute to its function.
The exterior of a phospholipid bilayer is hydrophilic, and the interior is hydrophobic (see figure above).
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Answer:
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Explanation:
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The true statement about a cell’s plasma membrane is that the plasma membrane regulates the movement of molecules and ions into and out of the cell. The correct option is D.
What is a plasma membrane?The plasma membrane or cell membrane is the outer covering of the cell. It is made up of lipids and proteins. Cell membranes serve to separate and group cells. Every cell has an exterior plasma membrane that controls both what and how much of any given material enters the cell.
Eukaryotic cells, unlike prokaryotes, have internal membranes that enclose their organelles and regulate the exchange of vital cell components. Both kinds of membranes have a unique structure that makes it easier for them to perform the gatekeeping job.
Thus, the correct option is D. The plasma membrane regulates the movement of molecules and ions into and out of the cell.

Hydrogen has an atomic number of one but has no neutrons if a hydrogen atom has a mass of three it would be
Answer:
tritium
Explanation:
a hydrogen atom with:
1 proton 0 neutrons = hydrogen
1 proton 1 neutron = deuterium
1 proton 2 neutrons = tritium
If the hydrogen has a mass of three, then it would be tritium
What it would be?An atom of hydrogen with an atomic number of one and a mass of three would be a hydrogen isotope called tritium.
Regular hydrogen (also known as protium) has one proton and no neutrons, giving it a mass of approximately 1 atomic mass unit (amu). Tritium, on the other hand, has one proton and two neutrons, giving it a total mass of about 3 atomic mass units (amu). This makes tritium a heavier and less common isotope of hydrogen.

Estimate the number of cells that belong to each phase of the cell cycle the. Explain how you made your decision and describe what occurs at each phase of mitosis
Answer:
There are two ways to do this. You could actually learn the phases and count each one. Since you're posting here, it's a safe bet you have no intention of actually learning the material. The second is to estimate based on the total number of cells. At any given time, you will have approximately the following percentages for each phase of the cell cycle:
Interphase - 96%
Prophase - 2.5%
Metaphase - .5%
Anaphase - .5%
Telophase - .5%
In the picture, there are about 120 cells. Now you have to do a little 5th grade math to calculate the approximate mumbers of each phase. So, for Interphase, we multiply 120 x .96 = 115. For Prophase we multiply 120 x .025 = 3. For Metaphase, Anaphase, and Telophase, we multiply 120 x .005 = .6, which rounds up to 1 each. Now, as I specified, these numbers are approximate. Looking at the picture, I count three that are in Metaphase, two that are in Anaphase, and at least three in Telophase. And there are more than three in Prophase. The best way to figure this out is to print the picture and, using a guide from the internet, count the cells in each phase, marking them off as you count them so that you don't recount them. Good Luck!

Explain briefly George Wofan's hypothesis about the origin of the earth.
Answer:
In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.
Explanation:
In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.
According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.
Any two geological Era are as follows:
Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.
Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.

False
Answer:
False
Explanation:
Adenosine triphosphate (ATP) is an organic compound or to be more specific an organic phosphate
ATP are under the category of nucleic acid biomolecule which are composed of organic compounds. Thus the statement is false.
What is ATP ?ATP or Adenosine triphosphate is the energy currency of the cell, organic compound composed of the phosphate groups, adenine, and the ribose sugar, synthesized in Mitochondria, therefore it is called powerhouse of the cell.
The ATP molecule was discovered by German chemist Karl Lohmann, these organic molecules involves the conversion of chemical energy from the digested food and used later for different cellular processes
In ATP molecule there are three phosphate groups present with high energy bonds involved in the liberation of energy after the break down which provides energy for various life processes.
The energy from ATP can be used in cellular processes like biosynthetic reactions, cell divisions, etc., it is mainly produced during cellular respiration where digested product of food can be utilized.
The ATP supply energy for transportation of different molecules, muscle contraction, blood circulation, locomotion and various body movements, switch to control chemical reactions and to send messages

The backbone vertebrae, skull, and rib cage make up the _______ skeleton. Among other types of cells, bone marrow produces _______ blood cells, which carry oxygen in the blood. _______ can eventually become osteocytes. If bones rapidly deconstruct faster than new bone tissue grows, this can lead to less dense and more fragile bones. When severe, this condition is called _______. _______ such as the MCL and ACL connect bone to other bone at joints.
Answers :
axial
red
Osteoblasts
osteoporosis
Ligaments
Osteoblasts are cells that build bone tissue, and are called osteocytes when they become surrounded by the bone that they have built. Osteoclasts are cells that break down bone tissue. The building and breaking down of bone tissue continues throughout a person’s lifetime and makes bones strong. If osteoclasts break down more bone than osteoblasts build, this can lead to osteopenia and osteoporosis, causing bones to be fragile and break more easily.
Answer:
1. axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
Explanation:
The axial skeleton consists of the bones of the head and trunk of a vertebrate including skull, and rib cage.
Bone marrow produces red blood cells, which carry oxygen in the blood.
Osteoblasts can become osteocytes, which are the third type of bone cells.
Osteoporosis is a bone resorption disease in which bones rapidly deconstruct faster than new bone tissue grows, and decreases the mechanical strength of bones.
Ligaments connects one bone to other at joint such as medial collateral ligament (MCL) and anterior cruciate ligament (ACL) that joins knee.
