Answers

Answer:

sun-->algae--> tadpole--> minnow-->Blue Heron--> alligator

Explanation:

The food chain for the following is: sun ---> algae ---> tadpole ---> minnow ---> Blue Heron ---> alligator.

What is food chain?"Food chain is the sequence of transfers of matter and energy in the form of food from organism to organism."

The food chain of the given organisms is as follows:

The sun is the ultimate source of energy. In its presence the green plants and algae make their own food.Tadpole is the larva of frog which gets its nutrition from the algae.Minnow are small fishes which eats larva. These are being eaten by blue heron (bird).At last the blue heron gets eaten by alligator.

The interconnection of more than one food chains are called food web.

Hence, the correct sequence is: sun ---> algae ---> tadpole ---> minnow ---> Blue Heron ---> alligator.

A. NE

B. NW

D. SW

Answers

Answer: SW

Explanation:I got it wrong and it gives you the right answer so thats that

The direction of wind is SW direction. Hence option D is correct.

What is wind?

Wind is defined as the air movement brought on by the Earth's rotation and the sun's uneven heating of the surface. The uneven heating of the Earth by the sun and the rotation of the Earth result in wind, which is the movement of air. Light breezes to natural disasters like hurricanes and tornadoes are all types of winds. In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or polluting the environment.

An anemometer can measure wind speed, and a weather vane or wind vane can detect wind direction. When put with anemometers, many wind vanes can be installed in numerous locations to calculate the overall wind profile of a specific area.

Thus, the direction of wind is SW direction. Hence option D is correct.

What causes the difference in humidity between Florida and Las Vegas

Answers

Answer:

yep

Explanation:

Little or no humidity is not so true anymore, with the building up and more greenery. Las Vegas the humidly is not at all that low as it once once

The difference in humidity between Florida and Las Vegas is primarily due to their geographic locations and climate patterns.

What causes the difference in humidity between Florida and Las Vegas?

Florida is located in the southeastern United States and is surrounded by water on three sides, with the Atlantic Ocean to the east, the Gulf of Mexico to the west, and the Straits of Florida to the south.

This proximity to water and the warm ocean currents that flow nearby create a humid subtropical climate, characterized by hot summers and mild winters with high levels of humidity throughout the year.

The low humidity in Las Vegas is due to the fact that the dry air has little moisture in it, leading to a lower amount of moisture in the atmosphere. Thus, there is a difference in humidity between Florida and Las Vegas.

Answers

Answer:

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live.  For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H ) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis. Two types of processes that contribute to the formation of the proton gradient are: processes that release H from compounds that contain hydrogen, and processes that transport H across the thylakoid membrane.

Answers

Complete question:

ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H+) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis.

Two types of processes that contribute to the formation of the proton gradient are:

processes that release H+ from compounds that contain hydrogen, and

processes that transport H+ across the thylakoid membrane.

Drag the labels to the appropriate locations on the diagram of the thylakoid membrane. Use only the blue labels for the blue targets, and only the pink labels for the pink targets.

Note: One blue target and one pink target should be left empty.

You will find the image and the labels in the attached files

Answer:

You will find the image and the answer in the attached files

Explanation:

Fosforilation of ADP to ATP occurs while electrons descend through the electron chain, from photosystem II to photosystem I.

Placed in the thylakoid membrane, there are molecules and complexes that participate in light-dependent reactions. The places that occupy these molecules in the membrane make possible ATP synthesis. Protons are released into the thylakoid space when the water molecules split in photosystem II. Membranes are impermeable to protons, so they can not leave the thylakoid space, nor enter without a protein transporter. Through the membrane, there is an electrochemical gradient as additional protons are pumped from the stroma to the thylakoid space, using the released energy as electrons move along the chain. ADP phosphorylates to ATP while protons move from the thylakoid space to the stroma in favor of the electrochemical gradient, through ATP synthase. ATP synthesis occurs in the stroma.

What is the flow of energy in a food web?

The flow of energy in a food web is the transfer of energy from one organism to another as they consume and are consumed by other organisms.

The energy flow in a food web typically starts with primary producers, such as plants, algae, and some bacteria, which convert sunlight or chemical energy into organic matter through photosynthesis or chemosynthesis.

For every higher level, only 10% of the energy of the lower level is transferred.

The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.

What are dihybrid crosses?

They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.

In this case, the two traits follow the Mendelian pattern and thus, assort independently.

Hence, the traits and their respective ratios would be:

Brown body, Red eyes - 9/16

Brown body, brown eyes - 3/16

Black body, red eyes - 3/16

Brown body, brown eyes - 1/16
