Fist thing is that question that help u on ur H.W

chickens can fly, although even wild chickens are not very good flyers. They don't need to be: they are ground living birds and will only fly short distances to escape predators or get up into trees to roost.

Chickens are capable of flight, however their domestication doesn't require it of them. After hundreds of years of being cultivated by humans, chickens have evolved to be less competent at flying than other birds. Chickens are ground feeders, which means they eat grubs and small plants. Since they do not need to hunt down prey like a hawk, they also do not need the wing strength to fly like one. Chickens are able to fly enough to access trees when they need to escape from predators.

What helps exploding pods disperse

Mariana [72]

Pods of certain plants such as gorse and pansies have a way of flinging their seeds when ripe in every direction with considerable force. The thing that helps these seeds disperse is first and foremost the mechanical force itself used to catapult the seeds.

As they ripen, the seed pods gradually lose moisture, building up tension in their cells and subsequently in the pod as a whole. The structure inevitably fails gradually and during a hot day it gives way altogether due to heat stress and triggers an explosion firing the seeds with appreciable force away from the parent plant almost like a projectile for up to 100m (300 ft) away.

It is important to note that plants which use this explosive method or ballistic dispersal as it is also called tend to have seeds that are generally large and too heavy to be carried by the wind unlike those of plants such as dandelions which are light enough for wind dispersal. Therefore gorse and suchlike plants employ ballistic methods to ensure their seeds travel as far away from the parent plant as possible.

Based on the results of the feeding experiment, what conclusions can you draw? select all that apply. (for help interpreting the

enyata [817]

The question posted above is incomplete, here is the complete version:

To find out which ingredient the cockroaches are refusing, you carry out a controlled experiment. Hydramethylnon is dissolved in oleic acid before being mixed with corn syrup to prepare the poisoned bait, so you should test all three ingredients. Suppose you conducted a feeding trial to test each ingredient. In the trial, a set of four agar dishes, three containing all except one ingredient and one with all three ingredients (the control), were weighed and placed 3 cm apart on the kitchen floor in an infested apartment. After two days, the dishes were weighed again to measure food consumption. You then repeated the trial 4 times and averaged the results. Here are the results from your experiment.

Tested (absent) diet component Average food consumed (mg/day)

Hydramethylnon 16

Oleic acid 12

Corn syrup 71

Control (all three ingredients present) 15

Based on the results of the feeding experiment, what conclusions can you draw? Select all that apply. (For help interpreting the results see the hints.)

1. Roaches ate about the same amount from the dish with no hydramethylnon as they did from the control dish.

2. Roaches ate about the same amount from the dish with no oleic acid as they did from the control dish.

3. Roaches ate about the same amount from the dish with no corn syrup as they did from the control dish.

4. Roaches are refusing hydramethylnon.

5. Roaches are refusing oleic acid.

6. Roaches are refusing corn syrup.

ANSWER:

The conclusions that apply include the following:

1. The roaches ate about the same amount from the dish without hydramethlynon as they did from the control dish.

6. Roaches are refusing corn syrup.

As we can see from the results obtained above, the amount of food consumed by the roaches when hydramethylnon is absent (16 mg/day)in the feed and that consumed from the control dish (15 mg/day)is almost the same quantity. From the results also, it can be seen that the highest quantity of food (71 mg/day) was consumed when corn syrup was absent in the feed, which implies that the roaches are refusing corn syrup.

What is the relationship between organisms that have blood?

True [87]

Answer:

There are three general types of symbiosis: mutualism, commensalism, and parasitism. Based on the nature of the interaction between organisms, symbiotic relationships are loosely grouped into one of these types. Mutualism is a mutually beneficial relationship in which both organisms benefit.

How many characteristics of life do you need to be considered living?

Alona [7]

There are 7 life processes: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition. You would need at least four or five characteristics to consider if an organism is living, mainly movement, respiration, growth, reproduction, and nutrition. (I might be wrong)
