what is the functions of genotypes???
Answer:
The genotype of an organism is its complete set of genetic material, two alleles are inherited for a particular gene by your parents sex gametes (sperm + egg). the genotype determines the persons phenotype eg. polydactyly, your eye colour etc, with a recessive or dominant allele. this can be determined through punnet squares too.
(1) what is active transpot and activesap (2)what happens if transportation does not occur answer me i will mark u as brainlist
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.
2.If the process of transpiration stops in plants, then the excess water inside the plants will not be able to come out. Hence, the plants will burst due to the presence of excess of water inside them.
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.

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.
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.

As you know, coronaviruses, influenza viruses, measles viruses, and rhinoviruses all encode RNA-
dependent RNA polymerases. All four of them introduce this gene into host cells. Two of them
ALSO introduce the RdRp enzyme. Which two? Why MUST they carry the polymerase protein in the
virus particle?
Answer:
In order to form more DNA molecules.
Explanation:
These viruses carry the polymerase protein in the virus particle because this protein synthesizes DNA molecules from deoxyribonucleotides. This formation of DNA molecule enables the virus cell to increase in their population. Each and every new cell of virus requires DNA molecules so we can say that this polymerase protein is very important and necessary for virus.

How are all fungi and all protists alike?
Explanation:
Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. As eukaryotes, both fungi and plants have membrane-bound nuclei, which contain DNA condensed with the help of histone proteins.

Which component would Chang use as the source of energy?
the battery
the switch
the wire
the light bulb
The battery component would Chang use as the source of energy.
What is Battery?Batteries consist of one or more cells, each of which undergoes chemical processes to produce an electron flow in a circuit.
Each battery has three primary components: an anode (the "-" side), a cathode (the "+" side), and an electrolyte of some sort.
When the cathode and anode of a battery are connected to a circuit, a chemical reaction takes place between the anode and the electrolyte. Following this reaction, electrons return to the cathode and experience a second chemical change.
Therefore, The battery component would Chang use as the source of energy.
