1. how would dr.budai refer to the new fern that contractors plan on introducing into the environment?

2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?

3. how might the building of the hotel affect the population of the new species?

Answers

Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.

Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.

The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Who are Primary consumers?

Primary consumers are herbivores, feeding on plants.Caterpillars, insects are examples of primary consumers because they only eat autotrophs (plants). Primary consumers are organisms that feed on producers.

When a forest is lost to fire, most of the plants (the producers) are lost. A major energy pathway is eradicated, reducing system productivity and shifting importance to energy supplied by primary producers.

Thus, primary consumers will compete heavily for the few plants that are left among themselves.

When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)

mitochondrion

cell membrane

cytoplasm

cell wall

Answers

Answer:

- cell wall -

Explanation:

The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.

So tell yourself does, an animal that already has a skeleton, need the cell wall?!

NO! It dan't! That's why animals don't have the cell walls and plants do.

!!! Hoped that helped !!!

When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.

What is cell wall?

A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.

It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.

The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.

It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.

The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.

Thus, the correct option is D.

what type of ions carry the impulse across the synapse from one neuron to the next ?

Answers

It's the sodium ion.

When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.

How do lenses correct vision?

A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.

Answers

Answer:  D

Explanation:

Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.

Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.

What is the function of lenses?

Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.

Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.

Answers

Answer:

Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.

Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.
