Answer:
Decomposers.
Explanation:
Decomposers are the organisms that obtain energy from dead organic matter and help in nutrient cycling. The example of such type of organisms are bacteria and fungi. These organisms feed on the dead bodies of plant and animals. It perform two function i.e. clean the environment by removing the dead body through feeding on it and add nutrients in the soil which helps the plants to grow more efficiently.

have a good day!
Organic compounds contain carbon atoms bonded to other atoms. The correct option is A.
What are organic compounds?Any of a wide area of chemical compounds in which one or many carbon atoms are covalently connected to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
The main distinction between organic and inorganic compounds is that organic compounds always contain carbon, whereas most inorganic compounds do not.
Furthermore, almost all organic compounds contain carbon-hydrogen or C-H bonds.
Organic foods are grown without the use of synthetic pesticides, fertilizers, or herbicides.
Organic meat, eggs, and dairy products are derived from animals that have been fed natural feed and have not been given hormones or antibiotics.
Thus, the correct option is A.

How is The processes of photosynthesis and respiration are interrelated
[tex]\color{Black}\huge{Answer} [/tex]
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.Answer:
Carbon dioxide and water are converted to oxygen and glucose through photosynthesis.
Oxygen and glucose are converted into water and carbon dioxide through cellular respiration.
By-products include water and carbon dioxide, while ATP is the energy generated by the process.
Explanation:
Plants use light water and carbon dioxide to make energy (glucose) and oxygen through photosynthesis. The oxygen is released into the atmosphere while the glucose powers the plant's operations. The process through which animals mix glucose and oxygen to make carbon dioxide and water is known as cellular respiration.
Photosynthesis end product is glucose utilised for the production of ATP in the cellular breathing. Glucose is then returned to carbon dioxide, needed for photosynthesis. During photosynthesis, the water is broken down into oxygen, but oxygen is mixed with hydrogen into water in cell respiration.

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood
the child has the blood type of Ab its obvious
Explanation:
only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele
Thus man's genotype: BO or
[tex] { | }^{b} i[/tex]
Woman's genotype : AO or
[tex] { | }^{a} i[/tex]

Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer:
See the attachment.
Hope u understand
In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.
A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.
Let the fixed charge for the first three days be x and the charge for each extra day be y.
From the given information, we can set up two equations:
For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]
For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]
We can solve for x and y by using elimination or substitution:
Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:
[tex]\rm 3x + 4y = 27[/tex]
[tex]\rm - (6x + 4y = 42)[/tex]
Solving above equations, we get:
[tex]\rm -3x = -15[/tex]
[tex]\rm x = 5[/tex]
Substituting x = 5 into one of the equations, we can solve for y:
[tex]\rm 3(5) + 4y = 27[/tex]
[tex]\rm 15 + 4y = 27[/tex]
[tex]\rm 4y = 12[/tex]
[tex]\rm y = 3[/tex]
Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

Which statement best describes the step in muscle contraction when the sarcomere is the shortest?
A The sarcomere is contracted, and the actin and myosin filaments are partially overlapped.
B The sarcomere is relaxed, and the actin and myosin filaments are partially overlapped.
C The sarcomere is contracted, and the actin and myosin filaments are completely overlapped.
D The sarcomere is relaxed, and the actin and myosin filaments are completely overlapped.
Answer:
C The sarcomere is contracted, and the actin and myosin filaments are completely overlapped.
Explanation:
In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.
In the sarcomere, which is the contractile unit of skeletal muscles, there are
Thick myosin myofilaments in the central region belonging to the A band. Thin filaments united to the Z lines, extending in the interior of the A band until they reach the border of the H band. Thin actin filaments composing the I band, which belong to two sarcomeres adjacent to a Z line.When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in the length of the sarcomere. The H line and the I band get shorter. The Z lines get closer to the A band, meaning that they get closer to each other. A band keeps constant in length. This change is produced by movement mechanisms that involve a change in the relative position of actin and myosin filaments.
