: Was the increase in the average beak depth caused by an increase in large-beaked finches or a decline in small-beaked finches?

Answers

Answer 1

Answer:

The increase in the average beak depth caused by both an increase in large-beaked finches and by a decline in small-beaked finches

Explanation:

The increase in the average beak depth is caused by both an increase in large-beaked finches and by a decline in small-beaked finches. All the small-beaked finches got disappeared. As a result, only large-beaked finches were left. The drought decreased the number of seeds such that large-beaked finches could eat the larger seeds to survive.

what some limitations found in photosynthesis experiment with the use of dicotyledous leaf ?​

Answers

Answer:

The history of net photosynthesis and transpiration per unit leaf area was determined for intact soybean leaves from their unfolding to senescence during flowering and pod filling on untreated (podded) and partially depodded plants growing in a glasshouse. Leaf diffusive resistances to CO2 were calculated and a water use efficiency parameter was derived (net mass of carbon dioxide fixed per unit mass of water transpired per millibar vapour pressure deficit). Net photosynthesis and transpiration behaved similarly through all stages of leaf development. A number of peaks were evident in these parameters. The first was associated with leaf expansion and occurred when the leaf reached its maximum area. The second peak coincided with flowering of the plant and later peaks occurred during pod filling. Stomatal and mesophyll resistances also exhibited similar behaviour during the life of the leaf; the possible causes of this linkage are discussed. Water use efficiency increased rapidly up to the time of full lamina expansion. Thereafter, it rose slowly or remained stable until leaf senescence approached, when the efficiency declined. Net photosynthesis and transpiration of leaves were very similar in both podded and partially depodded plants. It appears that to prevent a shortage of assimilate during flowering and pod filling, photosynthesis may be maintained or increased in some leaves and the response is not related to the number of pods available for filling. The increases in photosynthesis were correlated with both higher stomatal and mesophyll conductances. Mechanisms by which the plant may control leaf photosynthesis are discussed.

In May 2018, the Kilauea volcano on Hawaii's Big Island began to erupt, spewing lava over part of the island.

Which event are Hawaiians most likely to observe first in the areas covered by lava?

A. Mosses will grow in thin, rocky soil.
B. Lichens will grow on the cooled lava.
C. Trees will grow in thick, rich soil.
D. Grasses will grow in soil with organic matter.

Answers

Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.

What is succession?

The succession term refers to colonization and subsequent changes.

Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.

Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.

What is Primary succession?

In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.

It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.

In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.

Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.

After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.

First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.

Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.

Grasses and pioneers keep modifying the ground and making it better with time.

Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.

Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.

This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.

In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.

The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

If a flower is wilted, but not totally dead and withered yet, is the flower dead and it's dead flower body is in the process of decomposing, or is the flower like in the flower stage of being an old person, it lived and now it's old, but not dead yet?

Here's an example of the flower stage I mean. ^-^

Answers

I think it wouldn’t be dead until it looses all of its color and is able to crumple in your fingertips. So basically, it isn’t dead yet when it is wilted. But Its getting to the stage of being dead (like how old people are at that stage of their life where they will pass away soon).

To put it simply, the flower is not dead yet, it’s just “old” :D

the impact of extinction to the environment

Answers

Answer:

Changing systems are inevitable but likewise bring harsh and even uncontrollable effectsExtinction is especially harmful because of the concept of mutual or coexistence theorems in which certain animals depend on others We will examine the food chain: Say that grasshoppers go extinct and the lizards that eat them exclusively now have no food source. That effect transcends into a higher order as it climbs up the food ladder. Effectively these said lizards could have been controlling the bug population and effectively the grasshoppers controlled smaller micro organisms which now are left to their own devices given the extinction of the grasshoppers.effectively those microorganism can damage ecosystems and dramatically change the composition or animals and vegetation that exist in said area.

Answer:

1) it'll affect the chain reactions in the whole ecosystem and therefore, have a big effect on the environment.

2) if this happens then humans may lose the source of medicines as well, thus humans will be hit by a disease and there would probably be no cure, hence again affecting the biodiversity.

Explanation:

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.

Alternative names for thyroxine

T4; tetraiodothyronine; thyroxin

What is thyroxine?

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys. Thyroid hormones play vital roles in regulating the body’s metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones.

How is thyroxine controlled?

The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.

This hormone production system is regulated by a feedback loop so that when the levels of the thyroid hormones (thyroxine and triiodothyronine) increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone. This system allows the body to maintain a constant level of thyroid hormones in the body.

What happens if I have too much thyroxine?

The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This may be caused by overactivity of the thyroid gland (hyperthyroidism), as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre, which is a swelling of the neck due to enlargement of the thyroid gland. Other symptoms of thyrotoxicosis include intolerance to heat, weight loss, increased appetite, increased bowel movements, irregular menstrual cycle, rapid or irregular heartbeat, palpitations, tiredness, irritability, tremor, hair
