The walking catfish is a species of fish that walks on land using its pectoral fins. During drought conditions, when there is li

ttle water in its habitat, the walking catfish can use its pectoral fins to get across land to areas with water. Which of these will MOST LIKELY happen to a population of walking catfish over time if all nearest aquatic environments dry up permanently?
A. Walking catfish with small pectoral fins are more likely to survive a trip to distant areas of water. The population is likely to evolve to have smaller pectoral fins.

B. Walking catfish with large pectoral fins are more likely to survive a trip to distant areas of water. The population is likely to evolve to have larger pectoral fins.

C. Walking catfish with large pectoral fins and those with small pectoral fins are equally likely to survive a trip to distant areas of water. Both types survive, so evolution is unlikely to occur.

D. Walking catfish with large pectoral fins and those with small pectoral fins are equally likely to not survive the trip to distant areas of water. Both types of catfish will then become extinct. ​

What are the factors that affect the force of gravity between two objects?
Alecsey [184]

Answer:

Explanation:

Interesting question. Consider the formula that governs the gravitational formula

F = G * m1 * m2 / r^2

G is the gravitational constant. It does not change no matter where you are in the inverse, nor is it found to be different under normal circumstances. Since you have asked this in biology, you can assume that the circumstances are always normal./

m1 and m2 are masses in kg. The mass is invariant as well anywhere in the universe, except perhaps near or in a black hole.

r^2 is a distance in meters.

So the Force of gravity (in Newtons) varies directly as the masses involved and inversely as the distance squared.

List at least three medical or health uses of plants that are unrelated to photosynthesis
Ghella [55]

Dandelion

It is an overly proven diuretic and your livers best friend; it helps detox your entire body. It also contains potassium, and some have used it to treat eczema, intestinal problems and arthritis. Its leaves also help to regulate blood sugar.

Rosemary

This is one of the oldest plants in our diet. According to recent studies, rosemary can help slow the progression of Alzheimer’s decease. Also, its oils naturally fight bacteria and fungi in your body and home. Ofelia’s famous words in Hamlet “There’s rosemary, that’s for remembrance,” refer to the plant’s ability to strengthen memory by improving blood circulation in the brain.

Lavender

Since classical antiquity, people have used lavender for its anti-inflammatory and antiseptic properties. But its very fragrance can help with anxiety, migraine, insomnia and depression.

Aloe Vera

For years, people have used the secretions of this plant to treat burns, cuts or superficial infections. It’s great for digestion, also, if you take it with juice.

Thyme

The citric variation of this herb (Thymus citriodorus) is known for its positive effects on children’s digestion and its antibiotic and antifungal properties, particularly used for healing superficial wounds.

Celery

Better known for its sweet zest, celery is also a great diuretic. The seed extract of this vegetable reduces blood pressure in animals and yields sedative and anti-convulsive effects for humans. However, excessive consumption may cause photodermatitis.

Sunflowers

According to the Medical Horticultural Society of Massachusetts, “a tea made from the leaves of sunflowers is an astringent, a diuretic and an expectorant, and it also works to reduce fevers.” Consuming sunflowers helps alleviate cold symptoms, and its ability to remove toxic substances lead the Russian Government to use it for cleaning the floors at the Chernobyl Power Plant after the nuclear disaster.

Mint

Headaches, skin irritations, nausea, pain, diarrhea and bloating are some of the many symptoms that mint alleviates. It also helps with digestion and chest congestion. Some studies suggest that it has antibacterial and antiviral properties.

Nepeta cataria

This plant, whose common name changes depending on where you are (cat mint, catnip, cat’s basil) is famous for inducing hallucinatory states of mind in cats. But people can chew its leaves to alleviate toothaches, fevers (because it causes sweating) and as a sedative. It is also known to repel mosquitoes much more effectively than store bought repellent.

Basil

This is another medicinal tradition inherited from the Mediterranean; basil was first used in the Greco-Roman world to repel insects and as an antidote to scorpion’s poison. People in India commonly use it to treat stress, diabetes, and asthma. New studies also suggest that basil has antiviral and antioxidant properties.
