Answer:

Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which
diamong [38]

Answer:

Approximately 12,500 SARS-CoV-2 viruses

Explanation:

According to this question, the period described is 1mm in diameter. Since 1millimetre(mm) is 1000metre(m), this means that the period is 0.001m in diameter.

Also, the SARS-CoV-2 virus has a diameter of 80 nm (1nm = 10^9m).

Since 10^6nanometres (nm) or 1,000,000nm makes 1millimeter (mm), 80nm of the virus will be:

= 80/1,000,000

= 0.000080mm or 8 × 10^-5mm

To calculate how many of the SARS-CoV-2 virus will fit into the period, we divide the diameter of the period (in mm) by the diameter of the virus (in mm).

That is; 1 ÷ 8 × 10^-5

= 1/8 × 10^5

= 0.125 × 100,000

= 12,500

Therefore, approximately 12500 SARS-CoV-2 viruses will fit in the period.

UkoKoshka [18]

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it n
Paladinen [302]

Answer:

The correct answer is increasing the rate of cellular respiration in mitochondria.

Explanation:

In mammals like humans, the infection causes a rise or hike in the body temperature of an individual up to 2 - 3 degrees Celsius. Infection results in thermoregulation strategies control by the hypothalamus, of the host by immune system transmitted integration signals, hormonal and neuron lead and increase in metabolic reactions by the increase the rate of the cellular respiration takes place in the mitochondria and that elevate body temperature. Mitochondria releases energy in the form of ATP that helps in body temperature as it is an exothermic reaction.

The correct answer is increasing the rate of cellular respiration in mitochondria.

The thalamus ______. the thalamus ______. is a "bridge" that relays nerve impulses between the cerebrum and cerebellum via the m
nekit [7.7K]
I think the thalamus is the gateway to the cerebral cortex. Thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the mid brain and has extensive nerve connections to both. Its main function is to relay motor and sensory signals to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation, which is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.

How can a property of water contribute to its ability to change stream corridors and affect erosion and deposition patterns?
Svetllana [295]

Answer:

Water Shapes the Watershed Changes in runoff can increase erosion and sedimentation of the land surface. Excessive runoff can cause downstream flooding and accelerated erosion of the land.
