What would the climate be like without the greenhouse effect? Back to normal with no threat of global warming
Too cold for many living organisms
Mostly temperate near the equator and extremely cold at the poles
Extremely dry with no moisture in the air

Answers

Answer 1

Answer:

The correct answer is option B

The temperature could have been too cold for some of the organisms without greenhouse effect.

The average temperature of the earth could have been much lower than what is today.

It is the green house effect that the temperature is optimum for the survival of all the organism otherwise only that organism could have survived who can live at lower temperatures.

Answer 2

Answer:

it would be to cold cuz

Explanation:

Which best describes the lytic and lysogenic cycles?Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answers

Answer: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host

Lysogenic cycle is a method by which virus can replicate its DNA using the host cell mechanism. During this phase bacteria integrate its DNA in to host cell to make viral copy to infect the organism.

The lytic cycle is another way of the viral replicaton, it results in the destruction of infected cell and its membrane. In this cycle bacteria make viral DNA and viral protein and break and allow the newly produced virus to leave and now integrated to new cells to spread infection to other cell.

The answer is: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

In the lysogenic cycle a virus does not kill the host. Regarding the other statements, in the lytic cycle symptoms of infection appear, and, also, it is the main way of replicating virulent viruses.

Hair and nails are derived from cells of theA. skin.
B. bone.
C. blood.
D. fat tissue.

Answers

Answer:

The correct answer is option A. "skin".

Explanation:

Hair and nails are derived from cells of the skin. The cells of the skin have keratin, a protein that creates a protective barrier against the environmental factors that could affect them. The hair and nails are modifications of skin cells, that have keratin but with additional features. The hair is made of 95% keratin and is formed of three components: medulla, cuticle and cortex. The nail cells are made from keratin as well, forming a horn-like structure that is replaced by skin cells constantly.

The answer is A. Hair and nails are derived from cells of the skin.

What bonds are found inside a water molecule, and are between hydrogen and oxygen?

Answers

The bonds that are found inside a water molecule and are between hydrogen and oxygen are covalent bond, specifically polar covalent bond. The oxygen and hydrogen share electrons forming a covalent bond and due to the difference in electronegativity a temporary dipole is made. Hope this answers the question.

Final answer:

Inside a water molecule, hydrogen and oxygen are connected by polar covalent bonds. This results from oxygen's higher electronegativity, causing the shared electrons to spend more time near the oxygen atom, creating a polarity. Hydrogen bonds, although not found within single water molecules, exist between different water molecules and contribute to water's overall properties.

Explanation:

The bonds found inside a water molecule between hydrogen and oxygen are polar covalent bonds. A covalent bond is established when electrons are shared between atoms. In a water molecule (H2O), electrons are shared between hydrogen and oxygen. However, oxygen has a greater electronegativity than hydrogen, causing the shared electrons to spend more time closer to the oxygen atom, hence creating a polarity.

Sometimes, a weaker bond known as a hydrogen bond, which is a type of dipole-dipole interaction, can be found between water molecules. Although these are not found inside a single water molecule, they are crucial for the properties of water as a whole.
