Describe the basic structure of the cell membrane with regard to specific molecules. What is it made out of?
Answer: The cell membrane is made up of phospholipids and the overall name is the Phospholipid bi-layer
Explanation:
The cell membrane has two rows of phospholipids. A phospholipid is broken into two parts, the heads and tails. The heads are hydrophilic (water-loving) and point to the outside and inside regions making the inner and outer wall, while the tails are hydrophobic (water-hating) and face each other to make the inside of the membrane. There are also molecules of cholesterol and proteins throughout the membrane.
Phospholipids are the building blocks of a cell membrane. A single phospholipid molecule consists of two ends: the head and the tail.
What are phospholipids?Phospholipids are amphiphilic molecules with both hydrophobic and hydrophilic fatty acid chains.
They are found in all living organisms as the primary components of cell membranes. Nature contains a variety of phospholipid classes with varying polar moieties.
Phospholipids are glycerol esters, fatty acid esters, phosphoric acid esters, and other alcohol esters.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine are the most common phospholipids.
The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure.
These compartments are the inside and outside of the cell in the case of the plasma membrane.
Thus, this is the basic structure of the cell membrane with regard to specific molecules.

Brady took a cutting from a sweet potato vine in his family garden and placed the vine in a small vase filled with water. After about a week, tiny roots had begun to grow. What is this an example of
Answer:This is an example of asexual reproduction.
Explanation:
Reproduction is defined as the ability of living organisms to produce offspring, that is, new individuals of their type. Living organisms have developed many methods of reproducing. These can be either ASEXUAL or SEXUAL.
Asexual reproduction: In asexual reproduction, an individual produces an offspring by itself, that is, only one parent is present. This type of reproduction is common among flowering plants. Examples of asexual reproduction includes:
--> Fission
--> Budding
--> Spore formation
--> Fragmentation and
--> Vegetative propagation.
The sweet potato vine is reproduced by an asexual means known as vegetative propagation. Here, a new plant grows from any portion of an old one other than the seeds. When stem cutting are taken from the vine, new storage roots are formed within few days.
Brady took a cutting from a sweet potato vine in his family garden and placed the vine in a small vase filled with water. After about a week, tiny roots had begun to grow which is an example of - Asexual reproduction.

Explain how each type of infectious agent (bacteria, virus, fungi, and parasite) affects the body.
Answer:
bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.
Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.
fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.
Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.
An example of a nucleotide is?
A. cytosine, ribose, and deoxyribose
B. guanine, deoxyribose, and phosphate
C. uracil, deoxyribose, and phosphate
D. thymine, ribose, and phosphate
Answer:
B
Explanation:
A nucleotide always consists of 3 things:
1. A sugar group (either ribose or deoxyribose, ribose if the nucleotide is from RNA, deoxyribose if it is from DNA.
2. A phosphate group
3. A nitrogenous base (A/T/U/C/G) This base depends on whether you have RNA or DNA, U is only for RNA. DNA has either A/T or C/G but never U.
what happened to the
beak depth of finches born in 1978 compared to those born in 1976? Explain why you
think this occurred.
Answer:
Why do you think the average beak depth of the birds increased?
Explanation:
Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

Which of these non-renewable resources is used nowadays in vehicles to reduce pollution?Immersive Reader (1 Point) Compressed Natural Gas All of these Diesel Petrol
Answer:
Compressed Natural Gas
Explanation:
Nowadays there are a lot of car manufacturers designing cars for specific countries that run on Compressed Natural Gas. This is because burning natural gas has been proven to be much cleaner and environmentally friendly than burning petroleum or Diesel. Natural Gas produces the same energy as the other non-renewable resources used to power cars while at the same time drastically reducing all of the pollutants created by burning these resources.

how does cell division help in growth and development of somatic cells and in gamete formation?
════════ ∘◦❁◦∘ ════════
[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]
════════════════════
Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.
#see pic of how cells in our body divide during mitosis
#sorry i borrow this ans for my latex experiment :v
════════════════════
Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

What is the difference between flu viruses and the measles virus?
Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.
Explanation:
Explanation:
Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.
By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

Anatomy
Label each of the following structures or processes.
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
