What are the reasons for ultra-thin and transparent nature of epidermal cells?​

Biology
1 answer:
Basile [38]3 years ago
8 0

Answer:

Epidermal cells secrete the waxy hydrophobic substance cutin that polymerizes on the surface, forming a barrier to water evaporation. Epidermal cells are transparent because their plastids remain small and undifferentiated; hence light readily penetrates through to the photosynthetic tissues beneath the epidermis.

1. a wide variety of factors. heat, climate, weather, natural disasters that lower the population of prey animals, etc

2. well and example is this: it is getting hotter in Antarctica, causing the ice caps to melt. this change would make it harder for prey animals like penguins to find somewhere to live, thus making them easier food for predators. such as killer whales and polar bears.

3. the more trees we cut down to make room for buildings, for instance, causes many animals habitats to dissapear, the animals shortly after

Speech about Environmental pollution
Ymorist [56]

Good morning /afternoon to one and all present here

I am here to talk about environmental pollution.

Pollution - It is defined as the addition of any substance or energy to the environment that is in some harmful form is know as a pollution

It can also be called as environmental pollution.

The environmental pollution include  air pollution, water pollution, land pollution, noise pollution, light pollution, and plastic pollution

Air pollution:

It is caused mainly due to the smoke from automobiles and by the unwanted smoke sent out from factories.

They produce carbon monoxide and nitrogen oxides, ozone, lead, that leads to smog formation also causes damage to foliage It causes health issues like, heart disease, inflammation and irritation of breathing passages, breathing difficulties, particularly for people with asthma, reduced lung function,

Water pollution:

The release of substances into subsurface groundwater or into lakes, streams, rivers, estuaries, and oceans. It is caused due to the industrial waste that are disposed directly into the water.

People use the same water for drinking, washing clothes, washing animals and they take bath in the same water.

Land pollution:

This is caused by the artificial pesticides used. They pollute the soil and damage the crops and will infect the vegetables that  grow underground.

Noise pollution:

This is caused by the automobiles and the sound produced by the speakers.

Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase
Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.

When you are on the roller coaster at Carowinds, your adrenal cells near the kidneys
kicyunya [14]

Answer:

D. Cell signalling which is released by one type of cell and acts upon a different cell

Explanation:

According to this question, adrenal cells near the kidney releases an hormone called ADRENALINE, which causes the cells of the heart to beat faster. This is an example of CELL SIGNALLING because chemical signals released by adrenal glands causes/triggers a response in the heart cells.

The chemical signal released by the adrenal cells is the ADRENALINE HORMONE, which induces a response in cells that are different from the cells of release (adrenal cells).
