Answer:
hydrogen bonds
Explanation:
The nucleotides in a strand of DNA are held together by phosphodiester bonds (a specific type of covalent bond). The two strands of DNA are held together by hydrogen bonds that form between the nitrogenous bases in one strand and the nitrogenous bases in the other strand.
Those are the two types of bonds you will probably be required to know for a basic biology class.

¿De qué maneras son los espermatozoides diferentes a todas las otras células del cuerpo masculino?
Answer:
Los gametocitos masculinos, o espermatozoides, difieren de las células del cuerpo porque pueden entrar en meiosis y crear espermatozoides. En el ciclo de meiosis I, un espermatocito primario diploide ubicado en los túbulos seminiferosos de los testículos se divide en dos espermatocitos secundarios haploides. Las dos células se convierten en cuatro espermatozoides a través de la meiosis II.

There are many more but here are just a few.
Answer:
Protein is a nutrient your body needs to grow, as well as to support and maintain your life. ... For example, proteins help cells develop and communicate, act as enzymes and hormones, conduct the transport of nutrients throughout your bloodstream and repair damaged tissue. In other words, you can't live without protein.

Discuss 3 different types of mutations that can happen
Answer:
Explanation:
Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

Earth would break apart.
B.
Earth would be pulled into the sun.
C.
Earth would leave the solar system.
D.

iii. pioneer species
iv. climax community
a.This stable community results from the process of succession.
b. These simple and hardy plants first colonize barren ground or rock.
c. This organic component of soil is produced from decomposed organisms.
d. This is the process of changing an environment from bare rock and a few species to a complex community with many species.
Answer:
1. B (ferns)
2. A (glaciation)
3. B (the appearance of a particular organism)
4
i. C
ii. D
iii. B
iv. A
Explanation:
1. Pioneer species in succession refers to species that first colonize a barren land or rock. They include species that can adapt to the condition of the land and subsequently break it down for other organisms to grow. Pioneer species in primary succession include ferns, lichens etc.
2. Primary succession occurs as a result of effects or negative impacts on an area. Specifically, primary succession in an area of Alberta today occurs because of the effects of GLACIATION, which is the covering of land surface with ice.
3. The appearance of a particular organism such as pioneer species in an aquatic succession can be an indicator of primary succession.
4. * Humus is an organic component of soil that is produced from decomposed organisms.
* Primary succession is the process of changing an environment from bare rock and a few species to a complex community with many species.
* Pioneer species are simple and hardy plants that first colonize a barren ground or rock.
* Climax community is a stable community that results from the process of succession.
Put the following layers of the digestive tract wall in order from the lumen to the deepest layer: 1. lamina propria 4. digestive (mucous) epithelium 2. muscularis externa 5. serosa 3. submucosa 6. muscularis mucosae
Answer:
4. digestive (mucous) epithelium
1. lamina propria
6. muscularis mucosae
3. submucosa
2. muscularis externa
5. serosa
Explanation:
The first layer of the digestive tract, starting from the lumen, is the epithelium. This has different characteristics depending on the digestive tract section. Then there is a loose connective tissue called lamina propria. Next, there is a layer of muscle called muscularis mucosae. It is only present in the digestive mucosae. The next layer is the submucosa, which has dense connective tissue and the submucosal plexus. Then it follows the muscular externa, which has muscle, and it is in all the digestive tract except for the esophagus and stomach. Lastly, we have the serosa layer.

3. What is the definition of recessive and dominant?
4. What is the difference between genotype and phenotype? Write a 5 sentence
paragraph describing the difference between the two.
Answer:
Recessive: relating to or denoting heritable characteristics controlled by genes which are expressed in offspring only when inherited from both parents.
Dominant: Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Explanation:
Genotype and phenotype differences
Genotype Phenotype
The hereditary information of the organism in the form of gene in the DNA and remains the same throughout the life. The characters of an organism which are visible are known as phenotypes.
Same genotype produces same phenotype. Same phenotype may or may not belong to same genotype.
Present inside the body as genetic material. Expression of genes as the external appearence.
The genotype is inherited from the parent to the offspring. The phenotype is not inherited from the parent.
It can be determined by scientific methods such as the polymerase chain reaction. It can be determined by observing the organism.
It is affected by genes. It is affected by genotype and environmental conditions.
For eg., Blood group, eye colour, height, genetic diseases. For eg., Weight, physique, beak of birds

Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells. With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
