Answer:
Explanation:
The Biological Building Blocks are :
Carbohydrates.
One of the primary functions of carbohydrates is to provide your body with energy. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream.
Proteins.
They also play a central role in biological processes. For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.
Lipids.
Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.
Nucleic Acids.
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).Feb 26, 2020
Combinations.
In most living species, glucose is an important source of energy. During cellular.For example, hemoglobin is a combination of four polypeptide subunits.

Answer:
Protein, carbohydrates, ATP (Adenosine triphosphate), lipids and nucleic acids
Explanation:
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance
The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose
ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes
lipids store energy, insulation, cellular communication and protection
nucleic acids have to do with the storage and expression of genetic information

Explanation:
When does the process shown occur in the
cell cycle?
Answer:
S- phase replication.
Explanation:
Genetic material present within DNA molecules regulates cell growth, proliferation, and cell repair. The long-chain helical macromolecules of these deoxyribonucleic acids are formed from complex sequences called nucleotides; these four monomers are joined by strong covalent bonds (adenine, cytosine, guanine, thymine).
DNA coding regions are called genes-they hold the cell's basic instructions. Multiple nucleotides and even several chromosomes may contain genes. Typically, gene expression entails transcription into RNA, and translation into amino acids/ proteins. In the S phase of the cell cycle, DNA is copied by polymerases. Here, the chromosomes are unwound and DNA is copied during replication to produce identical strands.
Explain why you know thatFrom what you learned in the diffusion handbook, what is causing the patient's low arterial oxygen? diuron caused the coral to bleach.
Answer:
Anemia , ARDS (Acute respiratory distress syndrome) and Asthma.
Explanation:
Anemia , ARDS (Acute respiratory distress syndrome) and Asthma are the causes of low arterial oxygen in patient. this low arterial oxygen is also known as Hypoxemia. in this disease, the level of oxygen decreases in the blood which is causes many problems and disorder in the body of the patient because oxygen is very important for the normal functioning of the body. Diuron causes the coral to bleach by the removal of algae attached to the coral. due to this removal of algae, the whole colour of coral become whitish.

David is playing football when he suffers from a ruptured calcaneal tendon. The rupture is accompanied by abrupt pain and the calf muscle bulges due to the release of two muscles from their insertion. Name these two muscles.
Answer:
The correct answer is - The gastrocnemius and soleus muscles.
Explanation:
Achilles tendon or calcaneal tendon is a tendon that is inserted the gastrocnemius and soleus muscles in to heels and connects it to the calf muscles. This is a strong tendon present at lower end of calf. The insertion is takes place into the calcaneus.
The gastrocnemius and soleus muscles togeter makes a strong band of tissue, back of the leg. Achilles tendinitis is characterized as the ruptured calf muscles from the insertion due to intense exercise or running fast.
The two muscles which bulged in the calf are referred to as gastrocnemius
and the soleus.
These muscles are found in the heel and are attached to the achilles
tendon in the calf of the leg. The muscles assist in movement such as
running, walking and flexion of the legs.
In this scenario, we were told that the rupture occurred in the calf and
accompanied pain was as a result of two muscles in the calf bulging which
will most likely be the gastrocnemius and the soleus muscles.

1. The living conditions is dependent on the structure, function and interrelatedness of cell parts. A living cell is
composed of a small number of elements - - mainly carbon, hydrogen, nitrogen, oxygen, phosphorous and sulfur.
a. because of its small size and four available bonding electrons, carbon can join to other carbon atoms in chains and rings to form large and complex molecules (macromolecules; organic building blocks / amino
acids)
b. the essential functions of cells involve chemical reactions that involve water and carbohydrates, proteins,
lipids and nucleic acids
c. cell functions are regulated; complex interactions among the different kinds of molecules in the cell cause
distinct cycles of activities - - such as growth and division
d. most cells function within a narrow range of temperature and pH; at very low temperatures, reactions are

If the starting population of the prey is higher than the predators, the carrying capacity of the seals will be _________ than the carrying capacity of the whales.
Answer:
Explanation:
Lower
If the starting population of the prey is higher than the predator's, then the carrying capacity of the seal will be lower than the carrying capacity of the whale in future.
What is carrying capacity?Carrying capacity means the capacity of the ecosystem to provide the resources necessary for the survival of a particular species. It is different for different animals. Large animals have less carrying capacity than small animals.
In the given statement, it is given that initially the prey population was higher than the predator population. The whale is the predator of the seals. So the number of seals was higher initially. It would be advantageous for the whale.
Whales feed on the prey, and after a certain time, the prey population will decline and the whale population will increase. Initially, the carrying capacity of seals was high, but as the whale population increases, after some time the seal population will decline. In the future, the population of whales will increase more than that of seals. The carrying capacity of the seal will fall in the future.
Hence, the carrying capacity of the seal will fall in the future, but initially it was high.

how much time does a cell spend in cytokinesis
Answer:
Not very long, this process lasts about two seconds because the body needs cells to survive.
Explanation:
Answer:
Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell. Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.(There is no specific time,just until the proccess is complete)
Explanation:
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
