Answer:

B and C.

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.

Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

The correct options is B and C.

The correct answer is B combustion.

Lavoisier’s oxygen theory of combustion was one of his most notable contribution to science and earned him the title of the “father of modern chemistry”. He recognized the combustible property of oxygen and that phosphorus and other metallic elements increased in terms of weight when burned.

Relative to the transcription start site, where would the promoter and terminator be located?

Paladinen [302]

Answer:

Promoter is located upstream and terminator is located downstream relative to the transcription start site.

Explanation:

Transcription start site is the site from where the transcription starts which is denoted by +1. The sequence of nucleotides which is present backword to them called upstream sequence and nucleotide sequence which is present in the forward direction of transcription start site are called downstream sequence.

Promoter sequences are present upstream to the transcription start site and are denoted with a minus sign and terminator sequence is present downstream to the transcription start site.

fiasKO [112]

Mucus would most likely accumulate in the respiratory tract as a result of ciliary destruction.

Pertussis (whooping cough) is a highly contagious respiratory tract infection. A severe hacking cough is followed by the a high-pitched breath intake that sounds like "whoop" in many people. Before the vaccine, whooping cough was thought to be a childhood disease. Whooping cough now primarily affects children who have not received the full course of vaccinations, as well as teenagers and adults whose immunity has waned.

Deaths from whooping cough are uncommon, but most commonly occur in infants. That is why it is critical for pregnant women and others who will have close contact with an infant to be immunized against whooping cough. The best way to avoid pertussis is to get vaccinated. Check that you and your loved ones have received their pertussis vaccines.

The hypothalamus __________. The hypothalamus __________. influences the function of only one lobe of the pituitary gland synthe

Morgarella [4.7K]

Correct question:

The hypothalamus __________.

a) influences the function of only one lobe of the pituitary gland.

b) synthesizes all of the hormones produced by the pituitary gland.

c) regulates both reproduction and body temperature.

d) produces only inhibitory hormones.

Answer:

C) Regulates both reproduction and body temperature.

Explanation:

The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.

The hypothalamus’ main role is to keep the body in homeostasis as much as possible.

Homeostasis means a healthful, balanced bodily state.

The hypothalamus acts as the link between the endocrine and nervous systems to achieve this. It plays a part in many essential functions of the body such as: body temperature, thirst, appetite and weight control, emotions, sex drive, blood pressure and heart rate, production of digestive juices and balancing bodily fluids.
