Label the parts of the cell membrane
The cell membrane is the outer covering of a cell, and it's responsible for controlling entry and exit of material from the cell. Cell membranes, regardless of whether they exist in plants, animals, fungi or bacteria, are all made of the same basic components.
Phospholipids, proteins, carbohydrates, and cholesterol or sterols make up these elements.
Phospholipids
The phospholipid is the cell membrane's primary structural element. Amphipathic fats called phospholipids make up the bulk of the membrane. The red particles with the two yellow tails in the cell membrane below are phospholipids.
Proteins
Another crucial component of the cell membrane is made up of proteins. Large molecules known as proteins are created from lengthy sequences of amino acids.
Carbohydrates
Carbohydrates are the third essential component of cell membranes. Other substantial compounds derived from simple sugars are known as carbohydrates. In general, these molecules facilitate cell communication by serving as sites for chemical signaling molecules to bind to cells, such as hormones.

The image to the right illustrates a portion of a white blood cell. what process is occurring?
The process of phagocytosis is seen in the image above and the image to the right illustrates a portion of white blood cells.
Cells use this method to take in and transport particles into the cytoplasm.
Neutrophils, macrophages, and monocytes are the three types of cells that engage in phagocytosis.
In contrast to endocytosis, which involves liquids, phagocytosis internalizes solid particles like germs. Phagocytosis involves the following steps:
a. It is triggered by the presence of foreign particles nearby. The phagocyte develops surface glycoprotein receptors that improve its capacity to attach to the surface of the foreign particle as soon as it identifies it.
b. The phagocyte's membrane enlarges after attaching to the surface of the foreign particle and develops a layer to enclose it.
c. After being enveloped, it produces a vacuole known as a food vacuole. After that, the phagosome is inserted into the cell for digestion.
d. When lysosomes enter the cell through the cell membrane, the process of digesting the particles takes place. The food vacuoles are disassembled into their constituent parts. Waste materials are discarded while the necessary nutrients are absorbed.

The phylum Porifera comprises the sponges. Sponges are simple invertebrate animals that live in aquatic habitats.
The phylum name Porifera means pore-bearing. Sponges take their name from small holes that cover their bodies.
Epithelial cells form a skin-like layer on the outer surface of a sponge (Fig. 3.20 D). These cells protect and enclose the sponge; they can contract and shorten, moving the sponge body slightly. All sponges are filled with the pores that give the phylum its name.
These pores are sometimes also referred to as ostia, and they provide openings for water, which carries planktonic food and oxygen, to enter the sponge body.
which of the following statements describe mutations? point mutations can occur in any dna sequence. frameshift mutations can occur in any dna sequence. neutral mutations depend on the degeneracy of the genetic code. deleterious mutations occur only in protein-coding sequences of dna.
The degeneracy of the genetic code is necessary for neutral mutations.
Neutral mutation is defined as change in nucleotide which is neither detrimental nor beneficial. Because there is change in nucleotide but amino acid sequence remain same because of degeneracy of genetic code.
When a nucleotide is changed to another nucleotide which leads to change in codon but the changed codon codes for the same amino acid which was coded earlier. Because many codon may codes for the same amino acid and this phenomenon is called degeneracy of genetic code.
Changes in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome are referred to as mutations. RNA or DNA make up viral genomes. Mutations result from mistakes made during DNA replication, viral replication, mitosis, meiosis, or any other type of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation), which may then undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other types of repair,, or result in a mistake during replication (translation synthesis).

How might a mole rat's ability to undergo cellular respiration without oxygen be applied to human medicine?
Mole rats' capacity to undergo cellular respiration without oxygen might be put into human medicine by producing energy without using oxygen.
Can humans do cellular respiration without oxygen?Most of our cells can also respire anaerobically (without oxygen), but the reaction is much less efficient. Every molecule of glucose will yield 30 molecules of ATP under aerobic respiration, but just two with anaerobic respiration.
Organisms can also carry out respiration without oxygen in a process called anaerobic respiration. In human cells, anaerobic respiration come through a process known as fermentation. If a cell does not have adequate oxygen to undergo cellular respiration then fermentation permit glycolysis to continue to run.

Explain what would happen at the age of puberty to a girl’s body if it were unable to produce estrogen or progesterone and a boy’s body if it were unable to produce testosterone.
During puberty, hormones play essencial roles in the body and processes of growing up. If during that age a girl`s body is unable to produce estrogen or progesterone, it means that a few events won`t happen. One of them is the menstrual cycle. Both estrogen and progesteron work together for the maturation of oocytes, and in the lack of estrogen and progesteron, the girl wouldn`t be fertile, and besides that, the changes that the endometrium has to go through during the period wouldn`t occur. Also, changes in the body such as breast growth and hip enlargement will also be hampered, because they are associated to those hormones as well. In the case of a boy`s body being unable to produce testosterone, the sperm production would be affected, and the boy would be infertile. Other processes like hair and genital growth, muscle gain and voice deepening would be negatively affected.
The partial ionic character of a bond is related to the difference in the electronegativities of the bonded elements. The greater the δen, the the percent ionic character of the bond. Although there are many bonds that have 0% ionic character, no bond has 100% ionic character, which indicates that electron occurs to some extent in every bond.
The partial ionic character of a bond is related to the difference in the electronegativities of the bonded elements. The greater the EN, the greater the percent ionic character of the bond. Although there are many bonds that have 0% ionic character, no bond has 100% ionic character, which indicates that electron sharing occurs to some extent in every bond.
The term "ionic bonding" refers to a bond in which the ionic character is greater than the covalent character - that is, a bond in which the two atoms have a large electronegativity difference, causing the bonding to be more polar (ionic) than in covalent bonding, where electrons are shared more equally.
They crystallize. They have both high melting and boiling points. They are brittle and hard. They have higher fusion and vapourisation enthalpies than molecular compounds. When dissolved in water, they conduct electricity. Because ionic solids do not conduct electricity, they are also excellent insulators.
Any bond formed by two atoms is not purely ionic. Because the electron density remains shared between the atoms, all bonding interactions have some covalent character.

Cell respiration begins with one molecule of glucose and produces2 ATP and Lactic Acid36 ATP2 pyruvate2 ATP
The cellular respiration is the process in which the cell frees the energy stored within glucose and stores it in ATP molecules. This process is aerobic, which means that this process needs oxygen to occur.
There are three stages in this metabolic path:
First stage: Glycolysis, during this process, glucose is broken down to from 2 pyruvate molecules and 2 ATP molecules.
Second stage: Krebs cycle, during this process the pyruvate molecules obtained at the end of the glycolysis undergo a series of changes and the resulting molecule is acetyl-CoA, the energy released during this process is stored into 10NADH, 2 FADH₂, and 2 ATP molecules.
Third stage: Electron transport, this last stage occurs in the membrane of the mitochondrion, at the end of this process, 32 to 34 ATP molecules are created.
The net harvest of the complete process is 36 to 38 ATP molecules.
So, the correct option is 36 ATP

(b) To genetically engineer the original cell so that it would glow, the scientists had to obtain a suitable
gene.
(i) Describe the stages that a scientist would complete to obtain this gene.
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.

Hormone excretion involves the movement of molecules outside the cytoplasm. This is known as exocytosis.
What is exocytosis ?Exocytosis is a type of active transport and bulk transport in which molecules are transported out of the cell. Exocytosis, as an active transport mechanism, necessitates the use of energy to transport material.Exocytosis is a type of bulk transport because it involves the release of a large number of molecules. Exocytosis occurs via secretory portals called porosomes at the cell plasma membrane. Porosomes are permanent cup-shaped lipoprotein structures at the plasma membrane of cells, where secretory vesicles dock and fuse to release intracellular contents.Exocytosis involves the transport of membrane-bound secretory vesicles to the cell membrane, where they dock and fuse at porosomes, and their contents are secreted into the extracellular environment. Because the vesicle transiently fuses with the plasma membrane, this secretion is possible.To learn more about exocytosis refer :
