False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.
What are structural component of cell wall?Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.
Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

Lamarck's ideas on evolution were adopted by some Russian scientists, includingLysenko. Russian textbooks printed Lysenko's assertionthat workmen who develop strong muscles from working in the mines would produce children who would be born stronger. Which of the major elements of evolution by natural selection is violated by this assertion
Answer:
The acquired characteristics are inherited.
Explanation:
Lamarck was a French naturalist and biologist. Lamarck was considered to be the early proponent who occurred the biological evolution. He was will known all over the world as early evolutionists.
Lamarck believed that the living things grow directly in the upward direction from a simple to a more complex form.
In the context, the ideas on the evolution were adopted by the Russian scientist which includes Lysenko. The Russian textbooks printed the assertion of Lysenko assertion that workmen develops a strong muscles those who are working in the mines that would produce strong children.
Bu this assertion, it violated the acquired characteristics that are inherited.
a increase in breathing rate can be triggered by an increase in the carbon dioxide containing in the blood. the increase in breathing rate is caused by a mechanism called
when there is high concentration of co2 in our body then respiratory centre ( medulla and pons) get activated and it increase rate of respiration which decreases co2 concentration
The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing.
What is medulla?Medulla is defined as the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.

Explanation:
the reason this mouse shows natural selection is that the black mouses are more adapted to their environment compared to the tan mouses as the tan mouses are more easily spotted and eaten by the bird. since the black mouse is more adapted to it's environment it is more likely to live on and pass it's trait of the black fur color to it's offspring while the tan mouses are not.
this part too #stresscrying
Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.
Investiga un uso beneficioso (medicina o industrial) para las bacterias, virus y Hongos microscópicos. Explica brevemente su utilización.
Answer:
- Hongos: antibiótico penicilina
- Bacterias: producción de insulina para uso humano
- Virus: vectores basados en adenovirus para el desarrollo de vacunas
Explanation:
Los microorganismos son fundamentales para el desarrollo de diferentes tipos de aplicaciones industriales y medicinales. Por ejemplo, la penicilina es una sustancia sintetizada por el hongo Penicillium notatum, la cual es ampliamente utilizada como antibiótico debido a sus propiedades antibacterianas. Las penicilinas son antibióticos del grupo de los betalactámicos que tienen como núcleo un anillo central de beta-lactama, las cuales son capaces de destruir una amplia variedad de bacterias. Por otra parte, las bacterias pueden ser usadas para la generación de moléculas orgánicas con fines médicos. Por ejemplo, cepas de Escherichia coli han sido modificadas mediante técnicas de ingeniería genética con el objetivo de producir insulina humana, una hormona central en el metabolismo de la glucosa. Mediante técnicas de recombinación genética, el gen responsable por sintetizar insulina humana ha sido introducido en bacterias. Las cepas de E. coli son relativamente fáciles de cultivar en el laboratorio y por lo tanto permiten obtener grandes cantidades de esta hormona (insulina). Finalmente, existen ciertas tipos de virus inocuos para nuestro organismo los cuales han sido recientemente utilizados como vectores para el desarrollo vacunas. Mediante esta técnica de ingeniería genética, un determinado vector viral (por ejemplo, un virus de la familia de los adenovirus) es modificado genéticamente con el objetivo de insertar un fragmento de un agente infeccioso o 'antígeno' el cual individualmente es incapaz de producir daño. Las vacunas diseñadas a partir de vectores virales son inofensivas para el organismo pero son capaces de desencadenar una respuesta inmune contra el antígeno recombinante, generando de este modo una memoria inmunitaria en contra el agente infeccioso.
All of the following affect the temperature at which magma forms except what?
Except viscosity, all the other factors affect the temperature at which magma forms. Therefore, the correct option is D.
What is viscosity?Viscosity can be defined as a measure of the fluid's resistance to flow. Magma can be defined as a very hot molten or semi-molten substance that is formed due to volcanic eruptions. They are responsible for the formation of the igneous rocks.
There are many factors that affect the temperature at which magma forms:
Pressure-increasing pressure can raise the melting temperature of rocks, while decreasing pressure can lower it.Composition of source material: The composition of the rocks in the mantle can vary depending on the location and geological history of the region. Presence of water: Water can lower the melting point of rocks, which can lead to the formation of magma.But viscosity does not play any role in impacting the temperature at which magma forms. Therefore, the correct option is D.

Compare photosynthesis and cellular respiration. In what types of cells do these processes occur?
Answer:
Cellular respiration occurs in both plants and animals.
But photosynthesis occurs only in plants. But photosynthesis can happen to 4 animals. It is only an exception, however. Sea slug and pea aphid may perform photosynthesis, oriental hornet, spotted salamander.
Explanation:
ATP is the main energy source of the cell. The most important final product of cellular respiration.The two main final photosynthesis products are glucose and oxygen.
Some of the cellular respiration enzyme reactions occur in the cytoplasm but the bulk is in the mitochondria. Inside the chloroplast, photosynthesis occurs.NADH is the high-energy cellular respiration electron carrier, while NADPH is photosynthesized as a powerful electron carrier.In the cell chloroplasts, photosynthesis is carried out. This process gives energy directly or indirectly to all living organisms. Life on Earth would be no longer there without it.
Although photosynthesis needs energy and produces food, cellular breathing breaks food down and releases energy. Photosynthesis and respiration are carried out by plants while animals can only breathe.
