If the DNA molecule is only composed of four possible nitrogen bases, how can thousands of different proteins be formed from such a limited set of fixed shapes?

Answers

Answer:

nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations

Explanation:

A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid.  There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.

In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?

Answers

Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.

PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.

The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.

How do you think new proteins affect the fitness of children?

Answers

Answer:

it affects ALOT!

Explanation:

Although health initiatives promote increased physical activity in children, the physiologic outcomes have not been well characterized. This investigation examined the effects of programmed aerobic exercise on protein metabolism in children (n = 7; mean ± SEM: 9.14 ± 0.46 y old; weight, 32.1 ± 1.6 kg; height, 138 ± 2.5 cm; and body mass index, 16.21 ± 0.36 kg/m2 ) using 15N-glycine methodology. Boys (n = 5) and girls (n = 2) walked (5 d/wk, 3.2–6.4 km/d) for 6 wk. Criterion measures taken at baseline (Pre) and after the exercise program (Post) included anthropometric data, dietary assessment, nitrogen balance, nitrogen flux (Q), protein synthesis (PS), protein breakdown (PB) and net protein balance [(Net) = PS − PB]. After the walking program, there were no significant changes in body weight, fat-free mass or percentage of body fat, whereas height increased (P < 0.01). Energy and protein intakes were constant throughout the study. Nitrogen balance was significantly more positive Post than Pre (P < 0.05). There was a significant decrease in Q (P < 0.0001) with corresponding decreases in PS (P < 0.001) and PB (P < 0.01). These data provide the first evidence that programmed aerobic exercise alters whole-body protein utilization in healthy, nonobese children. Longitudinal studies are required to further examine changes in protein metabolism associated with increased physical activity in this population. In addition, findings suggest a need to evaluate nutrient requirements for healthy, physically active boys and girls.

Do mutations in body cells contribute to genetic variation?(1 point)

A) No, the causes of body cell mutations are outside the body and cannot alter DNA.

B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.

C) Yes, these body cell mutations lead to mutations in the gametes.

D) No, the mutations cannot be passed to offspring and only affect the individual.

Answers

A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.

The correct answer is:

Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.

Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.

The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.

The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.

Therefore Option B is correct.

FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. ... Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. 8.arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas a La glucosa b) El oxígeno. C) El dióxido de carbono d ) Oxígeno y dióxido de carbono

Answers

Answer:

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.

Explanation:

La fotosíntesis es un proceso metabólico que llevan a cabo determinadas células de organismos autótrofos, es decir, aquellas que tienen la capacidad de producir su propio alimento, como las plantas. Con este proceso, las plantas captan la energía de la luz solar y la transforman en energía química, para producir materia orgánica a través de materia inorgánica.

Los procesos que llevan a cabo las plantas en la fotosíntesis se llevan a cabo en 2 etapas: en la primera etapa las plantas absorben el agua del suelo a través de las raíces. A través de sus tallos lo transportan hasta sus hojas. En estos se encuentra el pigmento llamado clorofila, que además de darle a la hoja el color verde, capta la luz solar y rompe la molécula de agua (H₂O), separando el hidrógeno (H) del oxígeno (O₂). En esta etapa se almacena energía y se libera oxígeno al medio ambiente.

La otra etapa es capturar dióxido de carbono. Esto proporciona los átomos de carbono y oxígeno que, junto con el hidrógeno y la energía almacenada, formarán la molécula de glucosa.

Entonces, los estomas son poros en la superficie de las plantas, encontrándose mayoritariamente en las hojas y en menor medida en los tallos y otros órganos. En ellas transcurre el intercambio gaseoso mecánico, es decir que en este lugar sale el oxígeno y entra dióxido de carbono en la fotosíntesis.

Por lo que, como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.
