The myosin and actin could not connect, and the sarcomere would
be unable to contract.
What is a sarcomere muscle?Sarcomeres are rather stereotyped and are repeated in the course of muscle cells, and the proteins inside them can trade-in periods, which reasons the overall length of a muscle to trade. A character sarcomere consists of many parallel actins (thin) and myosin (thick) filaments.
What is the difference between sarcomere and myofibrils?Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide beyond each other when a muscle contract or relaxes.

Lipids serve as structural components of membranes;
Nucleic acids store and transmit genetic information
5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.
Explanation:
1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.
2. Carbon has the ability to form different large and complex structures because:
(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.
(ii) carbon can form single, double and triple with itself and other life elements.
(iii) the relative stability of the covalent bonds formed by carbon.
3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.
4. Carbohydrate provide energy; Proteins serve as structural elements;
Lipids serve as structural components of membranes;
Nucleic acids store and transmit genetic information
5. Polymers are large molecular weight compounds built up from subunits called monomers.
Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.
Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.

have been heated by the sun?
A) cool and moist
B) hot and very dry
C) warm and moist
D) cold and dry
I need this today please help
Answer:
I'm pretty sure its c
Explanation:
Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.
What are topical waters?Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.
A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).
Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.

Answer: carbohydrates, lipids, proteins, and nucleic acids
Explanation:
Please give me an answer and don’t confuse me because everybody is giving me different answers :(
Answer:
In plants and some protists, such as algae
Explanation:
Chloroplasts are organelles found in cells of plants and some protists, such as algae. They contain a pigment called chlorophyll, which makes them green. Thanks to this protein, they conduct photosynthesis - a process in which energy from sunlight is converted into sugars, i.e. food. In this process, oxygen is being released.

Which equation best represents conservation of matter?
A 6H2O + 6CO2 → C6H12O6 + 6O2
B 6H2O + 6CO2 → C3H6O3 + 3O2
C 3H2O + 3CO2 → C6H12O6 + 6O2
D 6H2O + 10CO2 → C6H12O6 + 4O2
Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.

Candice is examining a cell under a microscope. She has identified a cell wall, a nucleus, and chloroplast. What type of organism does this cell most likely belong to.
1.plant
2.fungus
3.animal
4.bacterium
Answer:
1. Plant
Explanation:
Only a plant has a cell wall, chloroplast, and nucleus. Since eukaryotes are the only ones with a nucleus, that cancels out bacteria and fungi. Since there is a chloroplast, you can tell that the cell has to be one of an autotroph which gives you plant.
Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.
The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.
The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.
Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

Answer:
results could be biased and therefore they are not reliable
Explanation:
A conflict of interest is generated when the authors of a given study have any type of interest that could influence their judgments, results and/or conclusions. These conflicts of interest include any relevant financial relationships, personal, religious, political or intellectual interests. To solve this situation, peer-reviewed, well-reputed journals generally include a conflict of interest statement where authors declare all interests that might be perceived as conflicting.
Root systems are classified as fibrous root systems and taproot systems.
Which property distinguishes the two types of root systems from each other?
A)
the method of water absorption
B)
the branching pattern of the roots
C)
the presence of xylem and phloem
D)
the growth rate of the roots
Answer:
B) the branching pattern of the roots
Explanation:
Plant roots function as anchors, food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.
Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems. While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.
Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.
Examples of these roots systems include...

Answer:
1. Archaea
2. Binomial nomenclature
3. Eubacteria
4. Eukaryote
5. Morphology
6. Prokaryote
7. Reproductive isolation
Explanation:
Archaea are microorganisms without a cell nucleus (i.e., prokaryotes), which were originally classified as Archaebacteria. Nowadays, procaryotic organisms are classified into two domains: Archea (Archaebacteria) and Bacteria (Eubacteria). These organisms are characterized by the lack of membrane-bound organelles. On the other hand, the domain Eukaryota consists of organisms that have their nuclei enclosed by a membrane. This domain is divided into four kingdoms: Protista, Plantae, Fungi and Animalia. Binomial nomenclature is a classification system to name species, where the first word of the name indicates the genus of the species and the second part of the name indicates the species within the genus. Finally, reproductive isolation is a term used to indicate physiological, mechanical, behavioral and geographical barriers that prevent interbreeding between two different species.
