Answer:

Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring

Explanation:

Reproduction in dogs is a <u>sexual process</u>. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce <u>diploid offspring.</u>

The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves <u>meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. </u>The random fusion of gametes further ensures that offspring from the same parents are different from one another.

Alexandra [31]

Answer:

The given blank can be filled with acquisition.

Explanation:

An unconditioned stimulus provokes the unlearned response and an unconditioned response is the naturally taking place reaction. A neutral stimulus is illustrated as the stimulus that prior to conditioning do not generate any kind of response.  

A type of learning wherein a subject begins to react towards neutral stimulus as it would perform with another stimulus by acquiring the path of associating the two stimuli is termed as classical conditioning.  

An acquisition can be illustrated as the time of learning in classical conditioning where an individual begins to associate a neutral stimulus with an unconditioned stimulus that further permits the neutral stimulus to begin possessing the conditioned response.

If ammonia is used as an energy and electron source by a bacterium, that bacterium would be considered a ___.
zhuklara [117]

If a bacterium uses ammonia as an energy as well as electron source, it is classified as lithotrophic chemotrophic.

<h3>Descriptive terms for lithotrophic chemotrophic:</h3>

Humans, fungi, and also many prokaryotes are chemotrophs that get their energy from organic chemicals. Lithotrophs are chemotrophs that obtain energy from inorganic substances such as hydrogen sulfide (H2S) as well as reduced iron. Lithography is a microbiological phenomenon that is unique in the globe.

<h3>What is the difference between chemoautotrophs and chemolithotrophs?</h3>

Chemotrophs are creatures that get energy from their surroundings by oxidizing electron sources. These compounds might well be organic (chemoorganotrophs) or inorganic (chemoorganotrophs) (chemolithotrophs). The term chemotroph is used in contrast to phototroph, which uses solar energy.
