A double helix. It best describes the structure of a DNA molecule. Moreover, the DNA is not a single stranded and it does not comprise amino acids

The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.

Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.

In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.

Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.

Answer:

The primary differences between animal and plant cells concern the types of organelles present within them. Although these cell types are similar in that they’re both eukaryotes, plant cells have several structures not present in animal cells: chloroplasts, amyloplasts, and cell walls.

The options given by Francis Collins to reconcile evolution and faith was in his argument that advances in science present “an opportunity for worship,” rather than a catalyst for doubt.

Francis Collins is known as an American physician-geneticist who discovered the genes associated with a number of diseases and led the Human Genome Project.

Francis Collins believed in seeing God as the creator of the universe – in all of its amazing complexity, diversity and awesome beauty – then science, which is, of course, a means of exploring nature, also becomes a means of exploring God’s creative abilities.

Francis Collins wanted to reconcile faith and evolution, and has been lauded for showing how a religious believer can rise to the highest levels of the scientific establishment while keeping his faith intact and while integrating his faith with his science.

Answer:

Half of the solar radiation is absorbed and converted to infrared (heat).

Explanation:

Solar radiation is the energy emitted by the Sun in all directions through space as electromagnetic waves.

The Earth’s surface has a significant impact on solar radiation.

When solar radiation reaches the Earth’s surface, it warms it up. However, the Earth’s average temperature does not change because the Earth radiates energy to the atmosphere and space. The outgoing radiation is at the Earth’s temperature and has its maximum in the infrared region of the spectrum.

Almost all solar radiation is absorbed by the ground, but only half of it is converted to infrared (heat). The other half is reflected back into space by the ground.

Blood pressure decreases below normal levels. blood flow to the heart decreases. heart is unable to pump as much blood. blood pressure decreases even more. this is an example of positive feedback.

Less than 120/80 mm Hg is regarded to be within the normal range for blood pressure. Keep up heart-healthy routines like maintaining a balanced diet and engaging in regular exercise if your findings fall into this category.

When readings are consistently between 120 and 129 systolic and fewer than 80 mm Hg diastolic, the blood pressure is considered to be elevated. Unless action is taken to control the condition, those with raised blood pressure are prone to develop high blood pressure.

If your blood pressure continuously falls between 80 and 89 mm Hg diastolic or 130 to 139 systolic, you have hypertension stage 1. Depending on your risk of developing atherosclerotic cardiovascular disease (ASCVD), which includes heart attack or stroke, doctors will likely advise lifestyle changes at this stage of high blood pressure.

Blood pressure that continuously ranges at 140/90 mm Hg or higher is considered to be in Stage 2 hypertension. Doctors would probably advise a mix of blood pressure drugs and lifestyle modifications at this stage of high blood pressure.

Getting medical help is necessary at this point in high blood pressure. You should wait five minutes before taking another reading if your blood pressure readings suddenly rise above 180/120 mm Hg. Don't wait to call your doctor if your levels are still unusually high. It's possible that you're going through a hypertensive crisis.

The 6 adaptations of camel are : long legs, drinks large amount of water, excrete less urine,hump stores fat,padded feet and long eyelashes.

1. Camel have lengthy legs to keep your body out of the hot sand.

2. Camel consumes a lot of water when it is available and then stores it in its body.

3. Camel have much less urine in their excretions, and their dung is dry. None of them perspire. A camel can go for several days without drinking water since it loses very little water.

4. A camel's hump is where fat is stored. The hump functions as a fat or energy reserve in times of need.

5. The camel has padded feet, which are big and flat and make it easier for it to move around on the sand. The padded feet prevent it from sinking into the sand in opposition to the weight of its own body and the load it is carrying.

6. Camel have long eyelashes and hairs to shield their eyes and ears from flying dust particles.

The type of telescope commonly used for see through dust and gas clouds with the intention of studying new stars is a radio telescope, because raido telescopes can be used to take pictures of newborn stars that are inside a giant gas cloud (when stars are born they are in clouds of gas) and the event of fusion of gases that initiate the stars formation.

The radio telescopes are made of a radio receiver and an antenna system that is used for detect radio-frequency radiation (30MHz to 300GHz) from stars, galaxies, and other extraterrestrial sources. The use of frequency analyze can determine structures that are far away from our planet, and the fact that those telescopes read radio-frequency turn easy to differentiate material sources, like the gases that are linked to the formation of stars, and others space structures.

Signaling molecules or hydrophobic ligands

Explanation: It sends messages through a chain of chemicals messengers inside the cell.

Hopefully this works :)

The molecules that are secreted by the nervous system are ligands (neurotransmitters), and they fit on the receptors present on the cell surface with which they are associated.

The neuron that is connected to the next neuron secretes some neurotransmitters at the axon end, and those fit the next neuron's receptors that are present on the cell surface. After the ligand-receptor interaction, the rest of the signaling starts in the neuron. Some of the neurotransmitters are excitatory in nature and activate the function, while others are inhibitory in nature and inhibit the function after attaching to the receptors.

Neurons are associated with muscles and glands, and they secrete the ligands that are neurotransmitters, and the receptors present on them work accordingly. In this way, the neurons regulate the body's functions.

Hence, the nervous system releases ligands (neurotransmitters) that fit into the receptors on the cell surface.

Answer: then it’s d there is less oxygen in cool water

Explanation:

There are many explanations for Michael's observation that fish breathe less frequently in cold water. However, his hypothesis that the fish returns to the cold water and requires less oxygen seems possible.

Fish are cold-blooded animals, which means their environment controls their body temperature. Their metabolic rate, activity level, and oxygen requirements decrease as water temperatures drop.

As a result, fish can slow down in cold water, reducing their oxygen demand and reducing their breathing rate.  Oxygen solubility may also play a role in whether fish breathe less in cold water. As the water temperature decreases, the ability of oxygen to dissolve in the water also decreases. Because of this, cold water can have less oxygen available, which can cause fish to breathe more slowly to compensate for the lack of oxygen.

Because fish need oxygen to digest food, they are likely to eat and breathe less. It's basically a joke that the fish are resting because fish don't have an obvious resting cycle and will move and swim when they are resting.

Finally, Michael's hypothesis that fish breathe less in cold water is plausible as it suggests that fish slow down and don't need as much oxygen.
