Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses

Answers

Answer 1

Answer:

Stresses such as lack of nutrients, space, competition and water availability.

Explanation:

Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.

Which factors affect the gravitational force between two objects?

Answers

Answer: The size of each object and the space between them.

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

3. Growth Zone is affected

Explanation:

1. Climate change affect the geography within which economy of the world operate: economic of the world are affected by change in climatic condition in the since that there is shift in the usual period of seasons. For example, taken Nigeria as a region in West Africa, rainfall is expected to start around March in almost all part of the country, however, due to climate change, some part don't still have rain till May. This causes a shift in farmers plan and affect the supply of farm produce to the local market and to the global market, in turn affecting the gross domestic product of the country.

2. It changes the comfortability of human within the global industry. Take for example, fossil fuel, it is part of human being to address some unfavourable conditions among which is climate change which causes global warming, during this period, the way industries and people uses fossil fuel are been changed and it have direct effect to global economy.

3. Growth Zone is affected: change in climatic condition changes world economy growth zones. Thus could be seen in transportation sector, when the water level is affected, international movement of cargoes by ship are affect and hence, some trades agreements are altered thereby changing the growth zone.

Which of the following actions would decrease global warming?
Select one:
Decreasing the amount of methane in the air.

Increasing the amount of oxygen in the air.

Increasing the amount of water vapor in the air.

Decreasing the amount of nitrogen in the air.

Answers

Answer:

Decreasing the amount of methane in the air

Explanation:

Methane is a powerful greenhouse gas, which absorbs the sun's heat and doesn't allow it to escape therefore contributing to global warming

Decreasing the amount of methane in the air would decrease global warming. Therefore, option (A) is correct.

What is global warming?

Global warming is the gradual increase in the Earth's average surface temperature, primarily due to the buildup of greenhouse gases in the atmosphere, such as carbon dioxide and methane. These gases trap heat and prevent it from escaping into space, leading to a warming effect on the planet.

The consequences of global warming are far-reaching and potentially catastrophic, including rising sea levels, more frequent and severe weather events, loss of biodiversity, and impacts on human health and well-being.

To address global warming, it is essential to reduce greenhouse gas emissions by transitioning to cleaner and more sustainable sources of energy, improving energy efficiency, and adopting more sustainable land use practices. Addressing global warming requires a collective effort from individuals, communities, businesses, and governments around the world.

In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.

1) what is the genotype of the spotted (recessive) parent?

Answers

Answer:

the spotted parent has the genotype ss

Explanation:

we will use s as the letter when describing the spotted trait.

since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss.  the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

A The new species can create excess nutrients in the soil that can damage native species

The series can harminative anime and damage the ecosystem

Answers

Answer:

Due to lack of biological gent.

Explanation:

Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.
