Answer:

Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.

Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

Answer:

I need an imago or a graph

Explanation:

Explanation:

As the ratio gets smaller, it takes longer for items to diffuse.

Explanation:

When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.

When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.

this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

Answer:

☁︎both positive and negative. for making ponds for other animals to live in but clearing large amounts of vegetation☁︎

Based on their activities, it can be concluded that Elephants have both positive and negative effects on their environment.

A habitat is refers to a place where a living organism is found.

The activities of an organism affects the habitat of that organism.

Elephants shape their environment in many ways, both positive and negative.

They can negatively impact their environment by changing a forest to a grassy field.

They can positively impact their habitats by creating new habitats from existing habitat such as by digging a hole that might become a pond.

Therefore, it can be concluded that  Elephants have both positive and negative effects on their environment.

Answer:

Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.

Explanation:

Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

Answer:

Due to presence at early days of the planet.

Explanation:

We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.

Explanation:

Answer:

Urbanization has many effects on surface albedo. It reduces it through the introduction of dark surfaces, through changing the surface geometry to better capture solar radiation, and through reducing snow cover in winter. It can also increase it by increasing the cloud cover and by emitting air pollutants and aerosols.

1. Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

2. Germination:When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light. Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits.

Answer:

They have homologous structures because they have a common ancestor.

homologous structures because they have a common ancestor is the most likely reason that horses and mountain goats have hooves.

Homologous structures shoe the same structure, but may have a distinct  function, it indicate a common ancestor.

A homologous structure is an organ or bone seen  common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor.

on the other hand analogous structures where two unrelated species have structures with similar forms or functions due to convergent evolution.

for example of a homologous structure is the wing of a bird and an insect.

Some of the antibiotics doctors prescribe to treat an ear infection such as  amoxicillin, cortisporin (neomycin/hydrocortisone) solution or suspension.

The infection is invasion and growth of germs in the body. The germs can be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it.

Antibiotics can have side effects as when children take antibiotics at the first sign of an ear infection, they are more likely to have vomiting, diarrhea, and allergic reactions because of the medicine. Also, antibiotics can kill “friendly” germs in the body and cause other problems like diarrhea.
