Answer:D
Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body
Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.
What is thermoregulation?Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.
During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.
Therefore, vasoconstriction and shivering signal the body to increase the temperature.

Differentiate between sub-cellular and acellular particles with examples
Answer:
Explanation:
Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.
While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).
Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.
Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.
Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.
Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

Explanation:
In order to determine whether you have hypoxia, your doctor will need to check the amount of oxygen in your blood. Therefore, option (C) is correct.
What do you mean by hypoxia?Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin.
Moreover, hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).
Hence, heart and lung function issues can lead to five categories of conditions that cause hypoxemia: ventilation-perfusion (V/Q) mismatch, diffusion impairment, hypoventilation, low environmental oxygen and right-to-left shunting.

Answer:
A Detritivore
Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

Help? You are studying an outcrop where the lower layer is limestone and the layer directly on top of the limestone is sandstone. Near the bottom of the sandstone layer are small, weathered pieces of limestone entirely contained within the sandstone. Explain how these pieces of limestone came to be contained within the sandstone.
Answer:
Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.
Explanation:
The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.

Answer:
The correct answer is E. intoxication caused by a focal C. tetani infection.
Explanation:
Clostridium tetani bacteria are found in the soil, in the feces and in the mouths of animals. The disease is acquired when wounds become infected by the bacteria. The spores become active and spread throughout the body producing a poison called tetanus toxin. This toxin blocks the nerve signals from the spinal cord to the muscles and can cause generalized severe muscle spasms (lockjaw) exacerbated by external stimuli or muscle spasms in areas adjacent to the wound.
Fomites are Group of answer choices insects that transmit pathogens from an infected host to a non infected host. animal sources for human pathogens. inanimate objects involved in the indirect contact transmission of pathogens. fecal material from infected hosts. silent carriers of infectious diseases.
Answer:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens.
Explanation:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens. These objects include a whole range of items mostly found in indoor environments. When pathogens such as viruses and bacteria come in contact with these objects through various human and animal activities such as sneezing or coughing, use of toilets etc; these pathogens remain active on these objects and can then cause disease when others come in contact with these objects.
Common fomites in the home include toilet seats and handles, doorknobs, kitchentops, bed coverings , mobile phones, light switches as well as as toys. In offices, door handles, stairway railings as well as wring materials are common fomites. Especially concerning is the issue of disease transmission by fomites in healthcare facilities since there is constant exposure of surfaces and equipments to various pathogens.
To help prevent the spread of diseases by fomites, regular handwashing and disinfection of commonly touched surfaces is required.
what are sex hormones?why are they named so? state their function.
Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...
