What is Earth’s current axial tilt?
what is the effect of Sunlight, carbon dioxide,
water vapor, methane
Answer:
Greenhouse effect
Explanation:
Carbon-dioxide, methane and water vapor are green house gases, these gases absorb a large proportion of sunlight been reflected by the surface of the Earth. These absorption of sunlight leads to gradual increase in the annual temperature of the Earth. This phenomenon is known as greenhouse effect.
Greenhouse gases include carbon dioxide, methane, and water vapor. These gases absorb a significant amount of the sunlight that is reflected off the Earth's surface.
What is Greenhouse gases?The progressive rise in the Earth's yearly temperature is caused by this absorption of sunlight. The term “greenhouse effect” refers to these phenomena.
Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gases are examples of greenhouse gases.
The warming effect of other greenhouse gases is amplified by an increase in atmospheric water vapor.
Earth's temperature rises in reaction to an increase in greenhouse gases like carbon dioxide and methane. This causes more evaporation from land and water surfaces.
Therefore, Greenhouse gases effect of Sunlight, carbon dioxide,
water vapor, methane.

Explanation:
What's the new peptide chain when the new DNA segment is translated?
Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine

What will happen if homogenisation and pasteurization steps are omitted during the production of yoghurt is:
There will be presence of harmful bacteriaThere will be a non uniform textureHomogenisation is the process of making two liquids become the same and that they do not separate. For example, during the production of milk, fat droplets are combined so that the cream does not break apart.The main aim of homogenisation is to make two soluble liquids uniform and combine and have similar texture.Pasteurization is the process of heating products, which can either be liquid or solid so that the harmful microorganisms and bacteria are removed. This is done to prevent spoilage and for preservation.The main aim of pasteurization is to eliminate pathogens and for preservation.Read more here:

Explanation:
A piece of metal has a mass of 10 g in a volume of 2 cm to the exponent of three what is the
Answer:
5g/cm³
Explanation:
Given parameters:
Mass of the metal = 10g
Volume of the metal = 2cm³
Unknown:
Density of the metal = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Insert the parameters and solve;
Density = [tex]\frac{10}{2}[/tex] = 5g/cm³
If the sequence of the template strands reads GCCATTAC, what is the base sequence of the mRNA strand?
Answer:
The base squence of the mRNA strand is CGGUAAUG.
Explanation:
The base sequence of the mRNA strand will be CGGUAAUG
The template strand refers to the sequence of DNA that is copied during the synthesis of mRNA.
RNA consist of four nitrogenous bases which are Adenine (A), Guanine(G), Cytosine(C) and Uracil(U)
During elongation,
Adenine pairs with Uracil
Guanine pairs with Cytosine
Thymine pairs with Adenine
Cytosine pairs with Guanine
From the question,
The given sequence is GCCATTAC
Therefore, the sequence of the mRNA strand will be CGGUAAUG
Hence, the base sequence of the mRNA strand will be CGGUAAUG

Explanation:
Which diagram best represents the cycling of respiratory and photosynthetic gases in green
algae?
Answer:
The correct answer is - option D.
Explanation:
In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.
In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.
So, the correct answer is - option D.
What process is the opposite of condensation ?
Answer:
Vaporization
Explanation:
Condensation is the transition from gas to liquid as in the condensation of steam to liquid water. Vaporization is the opposite from the liquid to the gas state. Melting is from the solid to the liquid state and freezing from liquid to solid.

The process that is the opposite of condensation is called evaporation.
What process is the opposite of condensation?Condensation and evaporation are two opposing processes that involve the transformation of matter between different states. Condensation occurs when a gas or vapor cools down and transforms into a liquid state. This process involves the release of heat energy.
The other one, evaporation, is the process in which a liquid changes into a gas or vapor state. It occurs when the liquid is heated, and its particles gain enough energy to escape from the liquid phase and enter the gaseous phase.
Concluding, evaporation is the opposite process of condensation, where a liquid transforms into a gas, while condensation is the process of a gas transforming into a liquid.
