Explanation:

What is the advantage to a tomato plant of having green unripe fruit and red ripe fruit? a. The fruit is more attractive to decomposing fungi and bacteria. b. The color change also causes the fruit to ripen faster since it absorbs more sunlight. c. This lessens the chance that immature seeds will be dispersed and increases the dispersal potential of mature seeds. d. The fruit is more noticeable to pollinators.

Answers

Answer: The correct answer is C.

This lessens the chance that immature seeds will be dispersed and increases the dispersal potential of mature seeds

Explanation:

This is because squirrels, birds, deers eat tomatoes fruits often. They eat the ripe tomatoes fruits which is more attractive to them. They take a bite and disperse the seeds but when there is both ripe and unripe tomatoes fruits, they will become confuse and think it's not okay to eat it. Therefore they won't feed more on it but they will rather prefer the red tomatoes. Therefore since both green and red are on it, consumption will be less as they prefer ripe ones

A tomato plant is also considered as a vegetable.

An advantage the tomato plant has in having both green unripe and yellow ripe fruit lessens the chance that immature seeds will be dispersed and increases the dispersal potential of mature seeds

As pollinators including birds and the likes love the ripe red fruit and also as a result of its attractiveness, they love to feed more on the red fruit than the green one. If a mix of the two is present they would be more focused on the red fruit than the green. This way the green immature seeds do not get dispersed before they gets matured.

Case-study.

A 25 years old male with past medical history of alcohol abuse was admitted to the ED with complains of severe lower back and bilateral legs pain. He had been running twelve miles every day for two weeks using 3 lbs weights attached to each leg and 2 lbs weights attached to each arm preparing for the marathon. The other complaint was a dark color urine for two days.
What is the cause of his symptoms. Explain the mechanism.


Answers

Answer:

The lower back pain and bilateral leg pain is due to over and intense physical activity which causes stretching of ligaments and muscles resulting in back and leg pain. Such pain can be managed by limited or by reducing physical activity.  The dark color of urine is due to the presence of bile (bilirubin) in the urine. Here the patient has a past medical history of alcohol abuse. Excessive alcohol intake enhances gut permeability resulting in enhanced absorption of bacterial endotoxins. Excessive endotoxins in the liver cause damage of the kupffer cells in the liver, resulting in the release of bilirubin in the blood which ultimately passes through kidneys into the urine.

Which letter indicates where the moon would be located during a lunar eclipse?
A. Position M
B. Position P
C. Position N
D. Position O

Answers

Answer:

B. Position P

Explanation:

If it is at "Position P", the Earth blocks the moon from the light from the sun, creating an eclipse.

Position P indicates the location of moon during a lunar eclipse. Hence, the correct statement is option B.

What is lunar eclipse?

A lunar eclipse is a celestial event that occurs during a full moon phase when the Earth passes between the Sun and the Moon, thereby, casting its shadow on the Moon which makes the moon a reddish-brown or coppery color, hence the moon is called "blood moon" during lunar eclipse.

A lunar eclipse only occurs when the Moon is in full phase and aligned with the Earth and Sun and can be visible from anywhere on the Earth. The lunar eclipse can last for several hours.

During a lunar eclipse, when Earth passes between the sun and the moon, it casts its shadow on the moon. The point at the moon's orbit where it is passing through the Earth's shadow is represented by position P which results in lunar eclipse.

Therefore, Position P indicates where the moon would be located during a lunar eclipse.

A woman goes to the doctor and is diagnosed with rheumatoid arthritis. What factors led to her developing this disease? Select all that apply. Some of her T cells were not negatively selected. Some of her T cells are not recognizing and associating with her major histocompatibility complex (MHC) proteins. Some of her T cells were not positively selected. Some of her T cells are recognizing and responding to her self antigens.

Answers

Answer:

Some of her T cells are recognizing and responding to her self antigens.

Explanation:

Rheumatoid arthritis is characterized as an inflammation in the joints. This inflammation is created by some T cells and their associations with antigens.

Right at the initial stage of the disease, T cells are activated by their own antigens, which makes them respond to this activation by recruiting monocytes and creating antibody-producing cells from the B lymphocyte. T cells also cause the release of free radicals and lysosomal enzymes, in addition to promoting an activation of the high imne complex. All of this, attacks the joints causing an inflammatory process at the site, which justifies the autoimmune character of this disease.

Autoimmune diseases are those in which the elements of an organism's immune system attack the healthy cells of the organism itself, as we can see in the paragraph above.

HELP PLEASE!! Field test is done on the milkweed in the wild and the clothianidin content per plant was about 1 ppb. larvae spend days in the wild eating the milkweed. how is this different from the experimental conditions? how would you design an experiment to test these conditions?

Answers

Answer:

In the question it is given that the milkweed with clothianidin above the 1ppb concentration will result in less successful hatching of monarch butterfly eggs. Along with the data from the experiments, the exposure of clothianidin on the monarch habitats will lead to a decrease in the population of the monarch butterfly initially. Then in later generations if any mutation occurs and a resistant butterfly is developed then the population of the monarch butterfly will recover. But without this mutation the population size will be reduced and the size and weight of the butterfly will also get reduced.

What are solar flares?A powerful concentrated outburst of electromagnetic radiation in the Sun's atmosphere is known as a solar flare. In areas where the sun is active, flares frequently coexist with solar particle events, coronal mass ejections, and other solar phenomena, albeit not always. The 11-year solar cycle affects how frequently solar flares occur.The acceleration of charged particles in the surrounding plasma caused by magnetic energy stored in the Sun's atmosphere is assumed to be the cause of solar flares. This causes electromagnetic radiation spanning the electromagnetic spectrum to be emitted.The daytime side of Earth's upper atmosphere, specifically the ionosphere, absorbs high-energy electromagnetic radiation from solar flares, preventing it from reaching the earth.
