The false statement about photosynthesis is Light energy from the sun is absorbed by pigments in the leaf and used to form glucose to be used by organisms in cellular respiration. The correct option is d.
What is photosynthesis?Photosynthesis is a chemical process by which plants make their food. The process includes sunlight which is trapped by chlorophyll, water, and carbon dioxide which is converted into glucose.
The glucose produced by plants is used by them to carry out their process of theirs, not the organisms in cellular respiration.
Thus, the correct option is d. Light energy from the sun is absorbed by pigments in the leaf and used to create glucose to be used by organisms in cellular respiration.

1.active transport. The movement of ions or molecules across a cell membrane in the direction opposite that of diffusion, that is, from an area of lower concentration to one of higher concentration. Active transport requires the assistance of a type of protein called a carrier protein, using energy supplied by ATP. SAP Activate is a content-rich and agile methodology for implementation and/or upgrade of SAP solutions across industries and customer environments. It sets out an innovative adoption framework that expedites SAP S/4HANA implementations.

A que tipo de comunicacion celular se refiere, los factores de crecimiento son señales que secretan las celulas para estimular su propio crecimiento y proliferacion
Answer: Comunicación intracrina
Explanation:
La comunicación celular consta de un proceso en el que las células se comunican entre ellas y con el medio externo mediante señales físicas o químicas. Entonces, dichas células reciben, procesan y transmiten señales no solo con su entorno sino también consigo mismas. Las señales que se originan en el exterior de una célula que son agentes físicos pueden ser, por ejemplo, la presión mecánica, la luz, la temperatura, el voltaje, etc. Las señales químicas pueden ser moléculas como péptidos, gases, etc. Dichas moléculas de señalización pueden sintetizarse a partir de diversas vías biosintéticas y liberarse a través de transportes pasivos o activos. Estas señales van a ser detectadas por receptores, los cuales son proteínas en la superficie celular o en el interior de la célula que detectan las señales y producen una respuesta. Los receptores de la superficie celular suelen unirse a señales o ligandos extracelulares, lo que provoca un cambio conformacional en el receptor que le lleva a iniciar una actividad enzimática o a abrir o cerrar la actividad de un canal iónico para permitir o bloquear el transporte. Por otro lado, los receptores intracelulares, como los receptores nucleares, tienen un mecanismo diferente, como el cambio de sus propiedades de unión al ADN y la localización celular en el núcleo, regulando directamente la transcripción de genes y por lo tanto la regulando la expresión génica.
La señalización celular puede producirse a corta o larga distancia, por lo que puede clasificarse como autocrina, yuxtacrina, intracrina, paracrina o endocrina. La señalización autocrina implica que una célula secrete una hormona o un mensajero químico que se une a los receptores autocrinos de esa misma célula, lo que provoca cambios en la propia célula. En la señalización paracrina, una célula produce una señal para inducir cambios en las células cercanas, alterando el comportamiento de éstas. Las moléculas de señalización conocidas como factores paracrinos se difunden a una distancia relativamente corta (acción local), a diferencia de la señalización celular por factores endocrinos, donde las hormonas recorren distancias más largas a lo largo del cuerpo y a través del sistema circulatorio. La señalización yuxtácrina es un tipo de señalización entre células o entre una célula y la matriz extracelular que requiere un contacto estrecho, entonces se diferencia de la comunicación autócrina y endócrina en que estas últimas no requieren contacto. Y por último, la señalización intrácrina es un mecanismo de control del crecimiento que implica la acción directa de factores de crecimiento dentro de la célula. Algunos factores de crecimiento producen complejos factor/receptor en la superficie celular y son rápidamente internalizados por la célula en cuestión y translocados al núcleo sin degradación.
Un factor de crecimiento es una sustancia natural capaz de estimular la proliferación celular, la curación de heridas y, en ocasiones, la diferenciación celular. Por lo tanto, actúan como moléculas de señalización entre las células y pueden actuar sobre las mismas células que las producen y liberan. Entonces, si estos factores de crecimiento actúan sobre las mismas células que los secretan, se habla de un comunicación intrácrina.

Which of the following statements is false? Question 1 options: Bcl2 blocks aggregation of BH123 on the outer mitochondrial membrane thus inhibiting apoptosis. BH123 proteins, like Bax and Bak, are death-promoting members of the Bcl2 family that induce the release of cytochrome c from mitochondria into the cytosol. Bcl2 proteins are part of the extrinsic apoptosis pathway. Some Bcl2 family members promote apoptosis, whereas others inhibit apoptosis.
Answer:
The correct answer is - Bcl2 proteins are part of the extrinsic apoptosis pathway.
Explanation:
The Bcl-2 family group of proteins that are known to either promote or inhibit the process of apoptosis by regulating the mitochondrial membrane potential. Bax and Bak are Bcl-2 proteins, act as pro-apoptotic proteins which oligomerize to result in forming pores in the membrane of the mitochondria.
These pores lead to the release of cytochrome c to the cytoplasm. Bcl-2 protein is an anti-apoptotic protein that inhibits the oligomerization of Bak and Bax.
Describe what happens by the end of anaphase.
a. The chromosomes in the cell become less tightly coiled.
b. The nuclear envelope disappears in the cell.
c. The mitotic spindle of the cell begins to form outside the nucleus.
d. The cell begins to elongate and the two poles have an equivalent collection of chromsomes.
e. The vesicles derived from the Golgi apparatus produce a cell plate at the middle of the cell that eventually forms the new cell wall.
Answer:
d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.
Explanation:
The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.

Answer:
Our digestive system has the ability to convert macromolecules into micromolecules.
Explanation:
Our digestive system has the ability to convert macromolecules into micromolecules with the help of certain enzymes. Carbohydrate is a macromolecule which is converted into glucose molecule with the help of saliva which is an enzyme present in the mouth, protein is also a macromolecule that is converted into amino acid so that our body cells can absorb it and fats are also macromolecules which can be converted into fatty acids with the help of digestive system. The cells produced waste materials such as carbondioxide gas and nitrogenous material which can be excreted through excretory system such as lungs and urinary bladder.

The diagram below shows the ways cells can release energy from food depending on whether oxygen is present.
Respond to the following:
What is the name for the top process (Hint: what is the term for a process that does need oxygen present to occur) ?
What is the name for the bottom process (Hint: what is the term for a process that does not need oxygen present to occur)?
How many ATP are produced at the end of the top process shown?
How many ATP are produced at the end of the bottom process shown?
Answer:
1. Aerobic respiration
2. Anaerobic respiration
3. 36 ATPs
4. 2 ATPs
Explanation:
According to the diagram attached to this question, the process of cellular respiration is described. Based on whether OXYGEN is present or not, cellular respiration can be divided into two:
- Aerobic respiration is the respiration that occurs in the presence of oxygen. As shown in the top process, aerobic respiration starts with glycolysis → krebs cycle → Electron transport chain (ETC). At the end of these three steps, 36 ATP molecules results.
- Anaerobic respiration is the respiration that occurs in the absence of oxygen. As described in the bottom process of the diagram, anaerobic respiration starts with glycolysis and enters alcoholic or lactic acid fermentation depending on which product is formed (alcohol or lactic acid). At the end of the process, only 2 ATP molecules is synthesized.
The DNA molecule could be compared
Answer:
The correct answer is -To a ladder.
Explanation:
Most commonly DNA molecule is considered and compared to a twisted ladder as the structure of DNA can be compared to a ladder. It makes the side of the ladder by an arrangement of alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder.
Nitrogenous bases that are purine and pyrimidine make up the 'rungs' or steps of the ladder and also bind with hydrogen bonds with one other in the rug as two bases make a single rug, and are attached to the backbone where the deoxyribose (sugar) molecules are located.
