How can a seedless vascular plant reproduce?
They reproduce by using xylem vessels.
They reproduce by producing flowers.
They reproduce by using spores.
They reproduce by carrying nutrients through phloem vessels.

Answers

Answer:

They reproduce using spores.

Explanation:

Seedless vascular plants (like ferns) do not have seeds. That means they do not have flowers because flowers produce fruit with seeds. To reproduce, they drop microscopic spores. These spores fly away in the wind and land wherever. Then they grow into new plants.

Write an explanation of why a scientist may want to perform an experiment about the effect of the concentration of salt on the amount of electricity produced. (2-3 Sentences)

Answers

Because Electrical energy needs in Pakistan are expected to continue to rise. The use of petroleum as a source of energy still dominates, although oil reserves in Pakistan are increasingly being depleted. Therefore, there is a need to develop alternative source of sustainable energy, such as Microbial Fuel Cell (MFC). MFC shows another type of renewable energy by changing natural matter into power with the help of microbes. In the present study, varied salt concentrations of a salt bridge in novel MFC design were analyzed. Sewage sludge was utilized, which contains a lot of organic materials and is additionally one of the major sources of ecological contamination, as substrate MFC. Saccharomyces cerverciae sp. (44 g) was used as a biocatalyst. Methylene blue (10 ml) was used as a mediator and potassium ferricyanide (100 ml) was used as an oxidizing agent for the conversion of sewage sludge into voltage generation using lab-scale double chamber MFC. Varied salt concentrations (1M, 3M and 5M of KCl and NaCl) of salt concentrations of salt bridge in a novel MFC design were analyzed. The maximum generated voltage, current, power, power density and current density with 1M KCl were 0.451 V, 0.0451, 0.0175561 mW, 0.000226001 mW/m2, 10.5166661 μA/m2 respectively. The MFC was run for a period of 1 day and readings were noted at regular intervals. The results obtained were helpful in designing an optimized MFC.

A scientist may want to perform such an experiment probably because they want to find out if there's another type of food or drink or spice that could create energy.

How can the difference in temperatures influence the wind patterns in the Atlanta area?


The unequal heating of Earth's surface can cause local winds to form. The less dense warmer air rushes in to replace the denser cooler air forcing the cooler air upwards creating the local winds in a given area.

Help me please giving brainliest

Answers

Answer:

1.

air (atmosphere)

water (hydrosphere)

land (geosphere)

organisms (biosphere).

2.

The Earth's climate is created by the interaction of the atmosphere and the hydrosphere. Heat and moisture are stored in the atmosphere, whereas water vapor is stored in the hydrosphere. The interactions between the two aid in the distribution of heat and moisture around the globe, resulting in temperatures that are conducive to life.

3.

The biosphere and hydrosphere interact in the sense that the hydrosphere provides water for the biosphere to function, grow, and exist. Animals (biosphere) consume water (hydrosphere), and fish (biosphere) require water (hydrosphere) in order to survive and swim. The flood is another interaction between the biosphere and the hydrosphere.

List 5 types of as3xual reproduction and give an example of an organism that uses each type.

Answers

The different types of as3xual reproduction are binary fission, budding, vegetative propagation, spore formation (sporogenesis), The following are examples of as3xual reproduction in unicellular organisms:Binary Fission - In binary fission, the parent cell divides into two equal halves called daughter cells, either transversely or longitudinally. Amoeba, for example, divides transversely, but Leishmania divides longitudinally.Several Fission - A parent cell divides into multiple daughter cells at the same time in multiple fission. Sporozoans, for example.Budding occurs when organisms create a bud on the surface of their body, which eventually develops into a distinct person. For instance, Budding Yeast.

How does the cell cycle start off?

Answers

Entry to the cycle is made in Gap 1 (G1) phase and this is followed in sequence by a DNA synthesis (S) phase, Gap 2 (G2) phase, and Mitosis (M). After mitosis (M) some cells enter the G1 phase of a new cell cycle whilst others may diverge at the start of G1 into a phase called Gap 0 (zero)

A new cell arises when one cell divides or when two cells, like a sperm and an egg cell, fuse. Either event sets off a cell-replication program that is encoded in the DNA and executed by proteins.

What is biodiversity, and why is it important?

See first comment too, please

Answers

Answer/Explanation:

Biodiversity is the shortened form of two words "biological" and "diversity". Biodiversity is required for the processes that support all life on Earth, which including us (Humans). Why is it important? It because without biodiversity we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing and several other resources.

Important reason include;

Biodiversity Protects Us. Biodiversity makes the earth habitable.Biodiverse ecosystems provide nature-based solutions that buffer us from natural disasters such as floods and storms, filter our water and regenerate our soils.Increase ecosystem productivity; each species in an ecosystem has a specific niche a role to playSupport a larger number of plant species and, therefore, a greater variety of crops.Protect freshwater resources.Promote soils formation and protection.

Tides
OVERDUE
Have another assignment like this that I’ll be uploading to a different question

Answers

Answer:

A-

Tides are caused mainly by             in how much the moon's gravity pulls on different parts of Earth.

The force of gravity pulls the moon and Earth toward each other.

The moon's gravity causes high tide on the side closest to the moon.

The moon's gravity pulls Earth, leaving water behind causing an additional high tide.

Low tides occur between the two high tides.

There are 2 low tides and 2 high tides a day.

B-

Their combined forces produce a tide with the greatest difference between consecutive high and low tides, called a spring tide.

Spring tides occur once a month, at new moon and at full moon.

During the moon's first-quarter and third- quarter phases, the line between the moon and the sun is at right angles to the line between Earth and the moon.

This produces a spring tide, a tide with the greatest difference between consecutive low and high These occur twice a month.
