<h2>A scientist examine a bacterium </h2>

The offspring created by bacteria with this gene will be resistant to the medication. The reason is that the bacteria reproduce by binary fission. If anyone carries a gene which makes it resistant to antibacterial medication.

Then its offspring will be resistant because in binary fission, DNA replicates and seperate. DNA replicates which possess the gene which makes it resistant to antibacterial medication then offspring will have that DNA which possesses such gene. Binary fission is a type of asexual reproduction.

-BARSIC- [3]

Answer:

Internal region of the brain and the hypothalamus are related to the sensation of thirst.

Thalamus is involved with the perception that the soda is not colder.

Explanation:

The central nervous system is the body system responsible for making your body receive information and respond appropriately, promoting full bodily functioning. It is formed by the brain, spinal cord and the components that form them.

Regarding the activities shown in the question above, we can say that some components of the brain are related. For example: The innermost part of the brain and the hypothalamus are related to feeling thirsty. This is because the inner part of the brain is responsible for making the brain understand how the organism is functioning, if something is missing or if there is any discomfort that needs to be resolved. The hypothalamus, in turn, is responsible for the release of hormones that signal that your body's homeostasis is unbalanced. With the interaction of these two structures you realize that you are thirsty.

In addition, the thalamus is responsible for allowing your body to receive sensory messages. It is this structure that allows you to realize that your soda is not cold when you touch the glass, or take a sip of it.

Choose a plant or animal that you think is interesting. describe some of the threats or challenges
Natasha_Volkova [10]

Answer:

If I were to choose a plant or animal which is interesting, I'd choose the "cactus."

Explanation:

A "cactus" is truly a splendid plant owing to its <em>ability to survive in the desert </em>or<em> periods of drought.</em> Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.

  • One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
  • Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
  • People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.

Based on the photoperiod there are two types of plants -  

a) Short day plant  

b) Long day plant

Here the term short and long day do not mean that the provided length of day are the critical length of day required for reproduction. But opposite to that it means that the length of the day required for reproduction must be  

a) Shorter than the defined length of day for short day plant  

b) And longer than the defined length of day for long day plant  

Chrysanthemums  is a short day plant and thus option 1 with 13L:11D will produce fully developed flower buds

Option A is correct 13L:11D

iren [92.7K]

Answer:

The most appropriate answer would be the first option.

Adaptive immunity is a part of the immune system which protects our body against infectious agents with the help of  B lymphocytes and T lymphocytes.  

It is characterized by its memory that is, it creates the memory of a lifetime for particular antigen or pathogen once it has come across.

As Adrian caught the virus a few years ago his immune system had developed a memory for the virus.  

So, as soon as his body contracted the same virus his body recognizes it easily and produce quicker and higher amplitude immune response against it.
